Accounting Policies [Abstract]
Organization	Note 1. Organization SmartStop Self Storage REIT, Inc., a Maryland corporation (the “Company”), is a self-managed and fully-integrated self storage real estate investment trust (“REIT”), formed on January 8, 2013 under the Maryland General Corporation Law. Our year-end is December 31. As used in this report, “we,” “us,” “our,” and “Company” refer to SmartStop Self Storage REIT, Inc. and each of our subsidiaries. We acquire, own and operate self storage facilities—including facilities owned by us as well as those owned by the entities sponsored by us. As of December 31, 2021, we owned 139 self storage facilities located in 18 states (Alabama, Arizona, California, Colorado, Florida, Illinois, Indiana, Maryland, Massachusetts, Michigan, New Jersey, Nevada, North Carolina, Ohio, South Carolina, Texas, Virginia, and Washington) and the Greater Toronto Area of Ontario, Canada, as well as 50 % equity interests in six unconsolidated real estate ventures located in the Greater Toronto Area. As of December 31, 2021, our unconsolidated real estate ventures consisted of five operating self storage properties and one parcel of land being development into a self storage facility, with subsidiaries of SmartCentres owning the other 50 % of such entities. As discussed herein, we, through our subsidiaries, also served as the sponsor of Strategic Storage Trust IV, Inc., a public non-traded REIT (“SST IV”) through March 17, 2021, and currently serve as the sponsor of Strategic Storage Growth Trust II, Inc., a private REIT (“SSGT II”) and Strategic Storage Trust VI, Inc., a publicly-registered non-traded REIT (“SST VI”) (SSGT II, SST VI, and prior to March 17, 2021, SST IV, the “Managed REITs”), and operate the properties owned by the Managed REITs, consisting of, as of December 31, 2021, 17 properties and approximately 12,000 units and 1.3 million rentable square feet. Potential and Completed Transactions Potential SSGT II Merger On February 24, 2022, the Company, SSGT II, and SSGT II Merger Sub, LLC, a Maryland limited liability company and a wholly-owned subsidiary of the Company (“SSGT II Merger Sub”), entered into a definitive Agreement and Plan of Merger (the “SSGT II Merger Agreement”). Pursuant to the SSGT II Merger Agreement, the Company will acquire SSGT II by way of a merger of SSGT II with and into SSGT II Merger Sub, with SSGT II Merger Sub being the surviving entity (the “SSGT II Merger”). The SSGT II Merger is expected to close during the second quarter of 2022. Assuming all of the conditions of the SSGT II Merger are satisfied and the SSGT II Merger is consummated in accordance with the terms in the SSGT II Merger Agreement, the Company will acquire all of the real estate owned by SSGT II, which as of February 24, 2022 consisted of (i) 10 self storage facilities located in seven states comprising approximately 7,740 self storage units and approximately 853,900 net rentable square feet, and (ii) SSGT II’s 50 % equity interests in three unconsolidated real estate ventures located in the Greater Toronto Area of Ontario, Canada. See Note 14 – Subsequent Events, for additional information related to the potential SSGT II Merger. SST IV Merger On March 17, 2021, we closed on our merger with SST IV (the “SST IV Merger”). As a result, we acquired all of the real estate owned by SST IV, consisting of (i) 24 self storage facilities located in 9 states comprising approximately 18,000 self storage units and approximately 2.0 million net rentable square feet, and (ii) SST IV’s 50 % equity interest in six unconsolidated real estate ventures located in the Greater Toronto Area of Ontario, Canada (the “JV Properties”). As of the merger date, t he JV Properties consisted of three operating self storage properties and three parcels of land in various stages of development into self storage facilities, jointly owned with subsidiaries of SmartCentres Real Estate Investment Trust, an unaffiliated third party (“SmartCentres”) . As a result of the SST IV Merger, approximately 23.1 million shares of SmartStop class A common stock ("Class A Shares") were issued in exchange for approximately 10.6 million shares of SST IV common stock. New Credit Facility On March 17, 2021, we, through SmartStop OP, L.P. (our “Operating Partnership”), entered into a credit facility with KeyBank, National Association as administrative agent, with an initial aggregate commitment of $ 500 million (the “Credit Facility”), which consisted of a $ 250 million revolving credit facility and a $ 250 million term loan. We used the initial draw proceeds of approximately $ 451 million primarily to pay off certain existing indebtedness as well as indebtedness of SST IV in connection with the SST IV Merger. On October 7, 2021, we amended the Credit Facility to increase the commitments on the revolving credit facility by $ 200 million, to $ 450 million. As a result of this amendment, the aggregate commitment under the Credit Facility is now $ 700 million. See Note 6 – Debt, for additional information. Equity The Company was formed on January 8, 2013 , under the Maryland General Corporation Law. We commenced our initial public offering in January 2014 , in which we offered a maximum of $ 1.0 billion in common shares for sale to the public (the “Primary Offering”) and $ 95.0 million in common shares for sale pursuant to our distribution reinvestment plan (collectively, the “Offering”) , marketed and sold primarily through retail investor channels, including the independent broker dealer channel . At the termination of our Offering in January 2017, we had sold approximately 48 million Class A Shares and approximately 7 million shares of Class T common stock (“Class T Shares”) for approximately $ 493 million and $ 73 million respectively. In November 2016, we filed with the SEC a Registration Statement on Form S-3, which registered up to an additional $ 100.9 million in shares under our distribution reinvestment plan (our “DRP Offering”). The DRP Offering may be terminated at any time upon 10 days’ prior written notice to stockholders. As of December 31, 2021, we had sold approximately 6.9 million Class A Shares and approximately 1.0 million Class T Shares for approximately $ 73.0 million and $ 10.6 million, respectively, in our DRP Offering. On October 29, 2019 (the “Commitment Date”), we entered into a preferred stock purchase agreement (the “Purchase Agreement”) with Extra Space Storage LP (the “Investor”), a subsidiary of Extra Space Storage Inc. (NYSE: EXR), pursuant to which the Investor committed to purchase up to $ 200 million in shares (the aggregate shares to be purchased, the “Preferred Shares”) of our new Series A Convertible Preferred Stock (the “Series A Convertible Preferred Stock”), in one or more closings (each, a “Closing,” and collectively, the “Closings”). The initial closing (the “Initial Closing”) in the amount of $ 150 million occurred on the Commitment Date, and the second and final closing in the amount of $ 50 million occurred on October 26, 2020. On October 19, 2021, our board of directors, upon recommendation of our Nominating and Corporate Governance Committee, approved an estimated value per share of our common stock of $ 15.08 for our Class A Shares and Class T Shares based on the estimated value of our assets less the estimated value of our liabilities, or net asset value, divided by the number of shares outstanding on a fully diluted basis, calculated as of June 30, 2021. As a result of the calculation of our estimated value per share, beginning in October 2021, shares sold pursuant to our DRP Offering are being sold at the estimated value per share of $ 15.08 for both Class A Shares and Class T Shares. On March 7, 2022, the board of directors approved the suspension of the Company's distribution reinvestment plan and share redemption program. See Note 12 – Commitments and Contingencies of the Notes to the Consolidated Financial Statements contained in this report for additional information. Prior to the termination of our Primary Offering, Select Capital Corporation, a California corporation (our “Former Dealer Manager”), was responsible for marketing our shares offered pursuant to our Primary Offering. SAM indirectly owns a 15 % non-voting equity interest in our Former Dealer Manager. Now that our Primary Offering has terminated, our Former Dealer Manager no longer provides such services for us. However, we pay our Former Dealer Manager an ongoing stockholder servicing fee with respect to the Class T Shares sold. See Note 10 – Related Party Transactions – Former Dealer Manager Agreement. Other Corporate History Our Operating Partnership was formed on January 9, 2013 . During 2013, Strategic Storage Advisor II, LLC, our former external advisor (“Former External Advisor”) purchased limited partnership interests in our Operating Partnership for $ 200,000 and on August 2, 2013, we contributed the initial $ 1,000 capital contribution we received to our Operating Partnership in exchange for the general partner interest. See Note 5 – Self Administration Transaction, for additional information. As we accepted subscriptions for shares of our common stock, we transferred all of the net Offering proceeds to our Operating Partnership as capital contributions in exchange for additional units of interest in our Operating Partnership. However, we were deemed to have made capital contributions in the amount of gross proceeds received from investors, and our Operating Partnership was deemed to have simultaneously paid the sales commissions and other costs associated with the Offering. In addition, our Operating Partnership is structured to make distributions with respect to limited partnership units that are equivalent to the distributions made to holders of common stock. Finally, a limited partner in our Operating Partnership may later exchange his or her limited partnership units in our Operating Partnership for shares of our common stock at any time after one year following the date of issuance of their limited partnership units, subject to certain restrictions outlined in our Operating Partnership’s limited partnership agreement. Our Operating Partnership owns, directly or indirectly through one or more special purpose entities, all of the self storage properties that we own. As of December 31, 2021, we owned approximately 89.2 % of the common units of limited partnership interests of our Operating Partnership. The remaining approximately 10.8 % of the common units are owned by current and former members of our executive management team or indirectly by SAM, its affiliates, and affiliates of our Former Dealer Manager. As the sole general partner of our Operating Partnership, we have the exclusive power to manage and conduct the business of our Operating Partnership. We conduct certain activities through SmartStop TRS, Inc. (our “TRS”), or other taxable REIT subsidiaries which are directly or indirectly wholly-owned subsidiaries of our Operating Partnership. COVID-19 Our rental revenue and operating results depend significantly on the demand for self storage space. Since the beginning of the COVID-19 pandemic in late March 2020, our operations have been affected by COVID-19 in various ways, including but not limited to, national and local jurisdictions issuing orders causing temporary restrictions on our business in certain markets, temporary shutdowns of certain of our facilities, customer behavior and their comfort levels visiting our facilities, as well as the broader economic impacts of COVID-19. The negative financial and operational impact associated with these items was most significant in the second quarter of 2020, with customer demand for self storage resuming at or above normalized levels during the second half of 2020, and through 2021. Future governmental orders or broad economic weakness could adversely impact our business, financial condition, liquidity and results of operations, however, the extent and duration to which our operations will be impacted is highly uncertain and cannot be predicted.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) as contained within the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and the rules and regulations of the SEC. Unaudited Information The square footage, unit count, and occupancy percentage data and disclosures included in these notes to the consolidated financial statements are unaudited. Principles of Consolidation Our financial statements, and the financial statements of our Operating Partnership, including its wholly-owned subsidiaries, are consolidated in the accompanying consolidated financial statements. The portion of these entities not wholly-owned by us is presented as noncontrolling interests. All intercompany accounts and transactions have been eliminated in consolidation. Strategic Storage Operating Partnership VI, L.P. (“SST VI OP”), the operating partnership of SST VI, and its wholly-owned subsidiaries, were consolidated by us until May 1, 2021. From March 10, 2021 (the date of our initial investment in SST VI OP) until May 1, 2021, the portion not wholly-owned by us was presented as noncontrolling interests, and all intercompany accounts and transactions were eliminated in consolidation during that period. Consolidation Considerations Current accounting guidance provides a framework for identifying a variable interest entity (“VIE”) and determining when a company should include the assets, liabilities, noncontrolling interests, and results of activities of a VIE in its consolidated financial statements. In general, a VIE is an entity or other legal structure used to conduct activities or hold assets that either (1) has an insufficient amount of equity to carry out its principal activities without additional subordinated financial support, (2) has a group of equity owners that are unable to make significant decisions about its activities, or (3) has a group of equity owners that do not have the obligation to absorb losses or the right to receive returns generated by its operations. Generally, a VIE should be consolidated if a party with an ownership, contractual, or other financial interest in the VIE (a variable interest holder) has the power to direct the VIE’s most significant activities and the obligation to absorb losses or right to receive benefits of the VIE that could be significant to the VIE. A variable interest holder that consolidates the VIE is called the primary beneficiary. Upon consolidation, the primary beneficiary generally must initially record all of the VIE’s assets, liabilities, and noncontrolling interest at fair value and subsequently account for the VIE as if it were consolidated based on majority voting interest. Our Operating Partnership is deemed to be a VIE and is consolidated by the Company as we are currently the primary beneficiary. Our sole significant asset is our investment in our Operating Partnership; as a result, substantially all of our assets and liabilities represent those assets and liabilities of our Operating Partnership and its wholly-owned subsidiaries. Additionally, from March 10, 2021 until May 1, 2021, we were deemed to be the primary beneficiary of SST VI OP, and their operations were therefore consolidated by us. Subsequent to May 1, 2021, we are no longer the primary beneficiary, and their operations are no longer consolidated by us. As of December 31, 2021, we were not a party to any other contracts/interests that would be deemed to be variable interests in VIEs other than our joint ventures with SmartCentres acquired in the SST IV Merger, which are all accounted for under the equity method of accounting (see Note 4 – Investments in Unconsolidated Real Estate Ventures for additional information), and our Tenant Protection Programs joint venture with SSGT II and SST VI, which are consolidated. As of December 31, 2020, we were also a party to and consolidated our Tenant Protection Programs joint venture with SST IV, which became a wholly-owned entity as a result of the SST IV Merger. Equity Investments Under the equity method, our investments will be stated at cost and adjusted for our share of net earnings or losses and reduced by distributions and impairments, as applicable. Equity in earnings will generally be recognized based on our ownership interest in the earnings of each of the unconsolidated investments. Investments in and Advances to Managed REITs As of December 31, 2021, and 2020, we owned equity and debt investments with a carrying value of approximately $ 11.0 million, and $ 15.1 million, respectively, in the Managed REITs; such amounts are included in Investments in and advances to Managed REITs within our consolidated balance sheets. We account for our equity investments using the equity method of accounting as we have the ability to exercise significant influence, but not control, over the Managed REITs’ operating and financial policies through our advisory and property management agreements with the respective Managed REITs. The equity method of accounting requires the investment to be initially recorded at cost and subsequently adjusted for our share of equity in the respective Managed REIT’s earnings and reduced by distributions. We record the interest on the debt investments on the accrual basis and such income is included in other in our consolidated statements of operations. Also included in Investments in and advances to Managed REITs as of December 31, 2021 are receivables from the Managed REITs of approximately $ 1.4 million. As of December 31, 2020, receivables from the Managed REITs approximated $ 0.5 million. For additional discussion, see Note 10 – Related Party Transactions. Noncontrolling Interests in Consolidated Entities We account for the noncontrolling interests in our Operating Partnership and the noncontrolling interests in our Tenant Protection Programs joint ventures with SSGT II and SST VI in accordance with the related accounting guidance. Due to our control through our general partnership interest in our Operating Partnership and the limited rights of the limited partners, our Operating Partnership, including its wholly-owned subsidiaries, are consolidated with the Company and the limited partner interests are reflected as noncontrolling interests in the accompanying consolidated balance sheets. We also consolidate our interests in the SSGT II and SST VI Tenant Protection Programs and present the minority interests as noncontrolling interests in the accompanying consolidated balance sheets. The noncontrolling interests shall be attributed their share of income and losses, even if that attribution results in a deficit noncontrolling interest balance . Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The current economic environment has increased the degree of uncertainty inherent in these estimates and assumptions. Management will adjust such estimates when facts and circumstances dictate. Actual results could materially differ from those estimates. The most significant estimates made include the allocation of property purchase price to tangible and intangible assets acquired and liabilities assumed at relative fair value, the ongoing fair value determination of contingent liabilities, the determination if certain entities should be consolidated, the evaluation of potential impairment of indefinite and long-lived assets and goodwill, and the estimated useful lives of real estate assets and intangibles. Cash and Cash Equivalents We consider all short-term, highly liquid investments that are readily convertible to cash with a maturity of three months or less at the time of purchase to be cash equivalents. We may maintain cash and cash equivalents in financial institutions in excess of insured limits, but believe this risk will be mitigated by only investing in or through major financial institutions. Restricted Cash Restricted cash consists primarily of impound reserve accounts for property taxes, insurance and capital improvements in connection with the requirements of certain of our loan agreements. Real Estate Purchase Price Allocation We account for acquisitions in accordance with GAAP which requires that we allocate the purchase price of a property to the tangible and intangible assets acquired and the liabilities assumed based on their relative fair values as of the date of acquisition. This guidance requires us to make significant estimates and assumptions, including fair value estimates, which requires the use of significant unobservable inputs as of the acquisition date. We engage third-party valuation specialists to assist in the determination of significant estimates and market-based assumptions used in the valuation models. The value of the tangible assets, consisting of land and buildings, is determined as if vacant. Substantially all of the leases in place at acquired properties are at market rates, as the majority of the leases are month-to-month contracts. We also consider whether in-place, market leases represent an intangible asset. We recorded approximately $ 21.5 million, none , and $ 13.6 million in intangible assets to recognize the value of in-place leases related to our acquisitions during the years ended December 31, 2021, 2020 and 2019, respectively. We do not expect, nor to date have we recorded, intangible assets for the value of customer relationships because we expect we will not have concentrations of significant customers and the average customer turnover will be fairly frequent. Allocation of purchase price to acquisitions of portfolios of facilities are allocated to the individual facilities based upon an income approach or a cash flow analysis using appropriate risk adjusted capitalization rates which take into account the relative size, age, and location of the individual facility along with current and projected occupancy and rental rate levels or appraised values, if available. Other factors considered as part of the purchase price allocation include historical operating data related to the properties, land sales comparisons, growth rates and discount rates. Acquisitions that do not meet the definition of a business, as defined under current GAAP, are accounted for as asset acquisitions. During the years ended December 31, 2021 and 2020, our property acquisitions did not meet the definition of a business because substantially all of the fair value was concentrated in a single identifiable asset or group of similar identifiable assets (i.e. land, buildings, and related intangible assets) or because the acquisitions did not include a substantive process in the form of an acquired workforce or an acquired contract that cannot be replaced without significant cost, effort or delay. As a result, once an acquisition is deemed probable, transaction costs are capitalized rather than expensed. During the years ended December 31, 2021, 2020, and 2019 we expensed approximately $ 0.9 million, $ 1.4 million, and $ 0.2 million, respectively, of acquisition-related transaction costs that did not meet our capitalization policy during the respective periods. Purchase Price Allocation for the Acquisition of a Business Should the initial accounting for an acquisition that meets the definition of a business be incomplete by the end of a reporting period that falls within the measurement period, we report provisional amounts in our financial statements. During the measurement period, we may adjust the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date and we record those adjustments to our financial statements. We apply any measurement period adjustments in the period in which the provisional amounts are finalized. As discussed in Note 5 – Self Administration Transaction, the Self Administration Transaction was an acquisition of a business. Evaluation of Possible Impairment of Real Property Assets Management monitors events and changes in circumstances that could indicate that the carrying amounts of our real property assets may not be recoverable. When indicators of potential impairment are present that indicate that the carrying amounts of the assets may not be recoverable, we will assess the recoverability of the assets by determining whether the carrying value of the real property assets will be recovered through the undiscounted future operating cash flows expected from the use of the asset and its eventual disposition. In the event that such expected undiscounted future cash flows do not exceed the carrying value, we will adjust the value of the real property assets to the fair value and recognize an impairment loss. For the years ended December 31, 2021, 2020, and 2019, no impairment losses were recognized. Goodwill Valuation We initially recorded goodwill as a result of the Self Administration Transaction. Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible assets and other intangible assets acquired. Goodwill is allocated to various reporting units, as applicable, and is not amortized. We perform an annual impairment test for goodwill, and between annual tests, we evaluate the recoverability of goodwill whenever events or changes in circumstances indicate that the carrying amount of goodwill may not be fully recoverable. In our impairment test of goodwill, we perform a quantitative analysis to compare the fair value of each reporting unit to its respective carrying amount. If the carrying amount of goodwill exceeds its fair value, an impairment charge will be recognized. See Note 5 – Self Administration Transaction for additional information. Trademarks In connection with the Self Administration Transaction, we recorded the fair value associated with the two primary trademarks acquired therein. Trademarks are based on the value of our brands. Trademarks are valued using the relief from royalty method, which presumes that without ownership of such trademarks, we would have to make a stream of payments to a brand or franchise owner in return for the right to use their name. By virtue of this asset, we avoid any such payments and record the related intangible fair value of our ownership of the brand name. As of December 31, 2021 and December 31, 2020, $ 15.7 million was recorded related to the SmartStop® Self Storage trademark, which is an indefinite lived trademark. As of December 31, 2021 and December 31, 2020, approximately $ 0.4 million and $ 0.5 million, respectively, was recorded to the “Strategic Storage ®” trademark, which is a definite lived trademark. The total estimated future amortization expense of the “Strategic Storage®” trademark asset for the years ending December 31, 2022, 2023, 2024, and thereafter is approximately $ 140,000 , $ 140,000 , $ 70,000 , and none thereafter, respectively. We qualitatively evaluate whether any triggering events or changes in circumstances have occurred subsequent to our annual impairment test that would indicate an impairment condition may exist. If any change in circumstance or triggering event occurs, and results in a significant impact to our revenue and profitability projections, or any significant assumption in our valuation methods is adversely impacted, the impact could result in a material impairment charge in the future. See Note 5 – Self Administration Transaction for additional information. Revenue Recognition Self Storage Operations Management believes that all of our leases are operating leases. Rental income is recognized in accordance with the terms of the leases, which generally are month-to-month. Revenues from any long-term operating leases are recognized on a straight-line basis over the term of the lease. The excess of rents received over amounts contractually due pursuant to the underlying leases is included in accounts payable and accrued liabilities in our consolidated balance sheets, and contractually due but unpaid rent is included in other assets. Managed REIT Platform We earn property management and asset management revenue, pursuant to the respective property management and advisory agreement contracts, in connection with providing services to the Managed REITs. We have determined under ASC 606 – Revenue from Contracts with Customers (“ASC 606”), that the performance obligation for the property management services and asset management services are satisfied as the services are rendered. While we are compensated for our services on a monthly basis, these services represent a series of distinct daily services in accordance with ASC 606. Such revenue is recorded in the Managed REIT Platform revenue line within our consolidated statements of operations. The Managed REITs’ advisory agreements also provide for reimbursement to us of our direct and indirect costs of providing administrative and management services to the Managed REITs. These reimbursements include costs incurred in relation to organization and offering services provided to the Managed REITs and the reimbursement of salaries, bonuses, and other expenses related to benefits paid to our employees while performing services for the Managed REITs. T he Managed REITs’ property management agreements also provide r eimbursement to us for the property manager’s costs of managing the properties. Reimbursable costs include wages and salaries and other expenses that arise in operating, managing and maintaining the Managed REITs’ properties. Under ASC 606, direct reimbursement of such costs does not represent a separate performance obligation from our obligation to perform property management and asset management services. The reimbursement income is considered variable consideration, and is recognized as the costs are incurred, subject to limitations on the Managed REIT Platform’s ability to incur offering costs or limitations imposed by the advisory agreements. We have elected to separately record such revenue in the Reimbursable costs from Managed REITs line within our consolidated statements of operations. Additionally, we earn revenue in connection with our Tenant Protection Programs joint ventures with our Managed REITs. We also earn development and construction management revenue from services we provide in connection with the project design, coordination and oversite of development and certain capital improvement projects undertaken by the Managed REITs. We recognize such revenue in the Managed REIT Platform revenue line within our consolidated statements of operations as the services are performed or delivered. See Note 10 – Related Party Transactions, for additional information regarding revenue generated from our Managed REIT Platform. Allowance for Doubtful Accounts Tenant accounts receivable is reported net of an allowance for doubtful accounts. Management records this general reserve estimate based upon a review of the current status of accounts receivable. It is reasonably possible that management’s estimate of the allowance will change in the future . As of December 31, 2021 and 2020, approximately $ 0.5 million and $ 0.3 million were recorded to allowance for doubtful accounts, respectively. Advertising Costs Advertising costs are expensed in the period in which the cost is incurred and are included in property operating expenses and general and administrative lines within our consolidated statements of operations, depending on the nature of the expense. The Company incurred advertising costs of approximately $ 3.7 million, $ 2.9 million, and $ 2.9 million for the years ended December 31, 2021, 2020, and 2019, respectively, within property operating expenses, and approximately $ 0.8 million, $ 0.6 million, and $ 0.7 million for the years ended December 31, 2021, 2020, and 2019, respectively, within general and administrative. Real Estate Facilities We capitalize costs incurred to develop, construct, renovate and improve properties, including interest and property taxes incurred during the construction period. The construction period begins when expenditures for the real estate assets have been made and activities that are necessary to prepare the asset for its intended use are in progress. The construction period ends when the asset is substantially complete and ready for its intended use. Depreciation of Real Property Assets Our management is required to make subjective assessments as to the useful lives of our depreciable assets. We consider the period of future benefit of the asset to determine the appropriate useful lives. Depreciation of our real property assets is charged to expense on a straight-line basis over the estimated useful lives Description Standard Land Not Depreciated Buildings 30 - 40 years Site Improvements 7 - 10 years Depreciation of Personal Property Assets Personal property assets consist primarily of furniture, fixtures and equipment and are depreciated on a straight-line basis over the estimated useful lives, generally ranging from 3 to 5 years , and are included in other assets on our consolidated balance sheets. Intangible Assets We have allocated a portion of our real estate purchase price to in-place lease intangibles. We amortize in-place lease intangibles on a straight-line basis over the estimated future benefit period, which is generally 18 months . As of December 31, 2021, the gross amount allocated to in-place lease intangibles was approximately $ 68.6 million and accumulated amortization of in-place lease intangibles totaled approximately $ 56.8 million. As of December 31, 2020, the gross amounts allocated to in-place lease intangibles were approximately $ 47.3 million and accumulated amortization of in-place lease intangibles totaled approximately $ 45.7 million. The total estimated future amortization expense of intangible assets related to our self storage properties for the years ending December 31, 2022, 2023, 2024, 2025, and thereafter is approximately $ 10.5 million, $ 0.2 million, $ 0.1 million, $ 0.1 million, and $ 1.0 million respectively. In connection with the Self Administration Transaction, we allocated a portion of the consideration to the contracts that we acquired related to the Managed REITs and the customer relationships related to the Tenant Protection Programs joint ventures. For these intangibles, we are amortizing such amounts on a straight-line basis over the estimated benefit period of the contracts and customer relationships. As of December 31, 2021, the gross amount of the intangible assets related to the Managed REITs contracts and the customer relationships related to the Tenant Protection Programs joint ventures was approximately $ 6.8 million and the accumulated amortization was approximately $ 4.3 million. As of December 31, 2020, the gross amount of the intangibles related to the Managed REITs contracts and the customer relationships related to the Tenant Protection Programs joint ventures was approximately $ 18.1 million and accumulated amortization of those intangibles totaled approximately $ 7.3 million. The total estimated future amortization expense for such intangible assets for the years ending December 31, 2022, 2023, 2024, 2025 and thereafter is approximately $ 0.7 million, $ 0.7 million, $ 0.7 million, $ 0.3 million and none thereafter, respectively. We evaluate whether any triggering events or changes in circumstances have occurred subsequent to our annual impairment test that would indicate an impairment condition may exist. If any change in circumstance or triggering event occurs, and results in a significant impact to our revenue and profitability projections, or any significant assumption in our valuations methods is adversely impacted, the impact could result in a material impairment charge in the future. See Note 5 – Self Administration Transaction for additional information. Debt Issuance Costs The net carrying value of costs incurred in connection with obtaining non revolving debt are presented on the balance sheet as a deduction from debt; amounts incurred related to obtaining revolving debt are included in the debt issuance costs line on our consolidated balance sheet (see Note 6 – Debt). Debt issuance costs are amortized using the effective interest method. As of December 31, 2021, the gross amount of debt issuance costs related to our revolving credit facility totaled approximately $ 4.1 million and accumulated amortization of debt issuance costs related to our revolving credit facility totaled approximately $ 0.8 million. As of December 31, 2020, the gross amount of debt issuance costs related to our revolving credit facility totaled none , and accumulated amortization of debt issuance costs related to our revolving credit facility totaled none . As of December 31, 2021, the gross amount allocated to debt issuance costs related to non-revolving debt totaled approximately $ 5.8 million and accumulated amortization of debt issuance costs related to non-revolving debt totaled approximately $ 1.9 million. As of December 31, 2020, the gross amount allocated to debt issuance costs related to non-revolving debt totaled approximately $ 12.0 million and accumulated amortization of debt issuance costs related to non-revolving debt totaled approximately $ 7.9 million. Organizational and Offering Costs We pay our Former Dealer Manager an ongoing stockholder servicing fee that is payable monthly and accrues daily in an amount equal to 1/365th of 1% of the purchase price per share of the Class T Shares sold in the Primary Offering. In accordance with the selling agreements we entered into with respect to the sale of Class T Shares, we will cease paying the stockholder servicing fee with respect to the Class T Shares sold in the Primary Offering at the earlier of (i) the date we list our shares on a national securities exchange, merge or consolidate with or into another entity, or sell or dispose of all or substantially all of our assets; (ii) the date at which the aggregate underwriting compensation from all sources equals 10 % of the gross proceeds from the sale of both Class A Shares and Class T Shares in our Primary Offering, which calculation shall be made by us with the assistance of our Former Dealer Manager commencing after the termination of the Primary Offering; (iii) the fifth anniversary of the last day of the fiscal quarter in which our Primary Offering (i.e., excluding our distribution reinvestment plan offering) terminated (or March 31, 2022); and (iv) the date that such Class T Share is redeemed or is no longer outstanding. Our Former Dealer Manager entered into participating dealer agreements with certain other broker-dealers which authorized them to sell our shares. Upon sale of our shares by such broker-dealers, our Former Dealer Manager re-allowed all of the sales commissions and, subject to certain limitations, the stockholder servicing fees paid in connection with sales made by these broker-dealers. Our Former Dealer Manager was also permitted to re-allow to these broker-dealers a portion of their dealer manager fee as marketing fees, reimbursement of certain costs and expenses of attending training and education meetings sponsored by our Former Dealer Manager, payment of attendance fees required for employees of our Former Dealer Manager or other affiliates to attend retail seminars and public seminars sponsored by these broker-dealers, or to defray other distribution-related expenses. We recorded a liability within due to affiliates for the future estimated stockholder servicing fees at the time of sale of Class T Shares as an offering cost. Foreign Currency Translation For non-U.S. functional currency operations, assets and liabilities are translated to U.S. dollars at current exchange rates. Revenues and expenses are translated at the average rates for the period. All adjustments related to amounts classified as long term net investments are recorded in accumulated other comprehensive income (loss) as a separate component of equity. Transactions denominated in a currency other than the functional currency of the related operation are recorded at rates of exchange in effect at the date of the transaction. Changes in investments not classified as long term are recorded in other income (expense) and represented a loss of approximately $ 3.8 million and a gain of approximately $ 0.6 million for the years ended December 31, 2021 and 2020, respectively. Redeemable Common Stock We adopted a share redemption program (“SRP”) that enables stockholders to sell their shares to us in limited circumstances. We record amounts that are redeemable under the SRP as redeemable common stock in the accompanying consolidated balance sheets since the shares are redeemable at the option of the holder and therefore their redemption is outside our control. The maximum amount redeemable under our SRP is limited to the number of shares we can repurchase with the amount of the net proceeds from the sale of shares under the distribution reinvestment plan. However, accounting guidance states that determinable amounts that can become redeemable should be presented as redeemable when such amount is known. Therefore, the net proceeds from the distribution reinvestment plan are considered to be temporary equity and are presented as redeemable common stock in the accompanying consolidated balance sheets. In addition, current accounting guidance requires, among other things, that financial instruments that represent a mandatory obligation of us to repurchase shares be classified as liabilities and reported at settlement value. When we determine we have a mandatory obligation to repurchase shares under the SRP, we reclassify such obligations from temporary equity to a liability based upon their respective settlement values. On August 26, 2019, our board of directors approved a partial suspension of our SRP, effective as of September 27, 2019, so that common shares were redeemable at the option of the holder only in connection with (i) death or disability of a stockholder, (ii) confinement to a long-term care facility, or (iii) other exigent circumstances . In order to preserve cash in light of the uncertainty relating to COVID-19 and its potential impact on our overall financial results, on March 30, 2020, our board of directors approved the complete suspension of our SRP, effective on April 29, 2020. Due to the complete suspension, we were unable to honor redemption requests made during the quarter ended March 31, 2020 or the quarter ended June 30, 2020. On August 20, 2020, our board of directors determined that it would be in our best interests to partially reinstate the SRP, effective as of September 23, 2020. As of December 31, 2021, our redemption program remained suspended other than for redemptions sought in connection with a stockholder’s death, qualifying disability, confinement to a long-term care facility or other exigent circumstances. On March 7, 2022, the board of directors approved the complete suspension of the Company's SRP. See Note 12 – Commitments and Contingencies of the Notes to the Consolidated Financial Statements contained in this report for additional information. For the year ended December 31, 2021, we received redemption requests totaling approximately $ 5.6 million (approximately 0.4 million shares), approximately $ 3.9 million of which were fulfilled during the year ended December 31, 2021, with the remaining approximately $ 1.7 million included in accounts payable and accrued liabilities as of December 31, 2021 and fulfilled in January 2022. For the year ended December 31, 2020, we received redemption requests totaling approximately $ 2.0 million (approximately 0.2 million shares), approximately $ 1.3 million of which were fulfilled during the year ended December 31, 2020, with the remaining approximately $ 0.7 million included in accounts payable and accrued liabilities as of December 31, 2020 and fulfilled in January 2021. For the year ended December 31, 2019, we received redemption requests totaling approximately $ 4.9 million (approximately 0.5 million shares), approximately $ 4.5 million of which were fulfilled during the year ended December 31, 2019, with the remaining approximately $ 0.4 million included in accounts pay

(2) Included herein is an addition to our Riverview, Florida property of approximately $ 2.3 million, which added 25,400 net rentable square feet and approximately 150 additional units, and opened in June of 2021. The (3) Such activity represents the acquisition of a property completed by SST VI OP, which as of the acquisition date was Merger with Strategic Storage Trust IV, Inc. On November 10, 2020, we, SST IV Merger Sub, LLC, a Maryland limited liability company and a wholly-owned subsidiary of ours (“SST IV Merger Sub”), and SST IV entered into an agreement and plan of merger (the “SST IV Merger Agreement”). Pursuant to the terms and conditions set forth in the SST IV Merger Agreement, on March 17, 2021 (the “SST IV Merger Date”), we acquired SST IV by way of a merger of SST IV with and into SST IV Merger Sub, with SST IV Merger Sub being the surviving entity. On the SST IV Merger Date, each share of SST IV common stock outstanding immediately prior to the SST IV Merger Date (other than shares owned by SST IV and its subsidiaries or us and our subsidiaries) was automatically converted into the right to receive 2.1875 Class A Shares (the “SST IV Merger Consideration”). Immediately prior to the SST IV Merger Effective Time, all shares of SST IV common stock that were subject to vesting and other restrictions also became fully vested and converted into the right to receive the SST IV Merger Consideration. As a result of the SST IV Merger, we acquired all of the real estate owned by SST IV, consisting of 24 wholly-owned self storage facilities located across nine states and six self storage real estate joint ventures located in the Greater Toronto Area of Ontario, Canada. As of the SST IV Merger Date, the real estate joint ventures consisted of three operating properties and three properties in various stages of development. The following table reconciles the total consideration transferred in the SST IV Merger: Fair Value of Consideration Common stock issued $ 231,412,470 Cash (1) 54,250,000 Other 365,703 Total Consideration Transferred $ 286,028,173 (1) The approximately $ 54.3 million in cash was primarily used to pay off approximately $ 54.0 million of SST IV debt that we did not assume in the Merger, as well as approximately $ 0.3 million in transaction costs. We issued approximately 23.1 million Class A Shares to the former SST IV shareholders in connection with the SST IV Merger. The estimated fair value of our common stock issued was determined by third party valuation specialists primarily based on an income approach to value the properties as well as our Managed REIT Platform, adjusted for market related adjustments and illiquidity discounts, less the estimated fair value of our debt and other liabilities. These fair value measurements are based on significant inputs not observable in the market and thus represent a Level 3 measurement as discussed in Note 2 – Summary of Significant Accounting Policies. The key assumptions used in estimating the fair value of our common stock included a marketability discount of 6 %, and projected annual net operating income, land sales comparisons, growth rates, discount rates, and capitalization rates. The following table summarizes the relative fair values of the assets acquired and liabilities assumed in the SST IV Merger: Assets Acquired: Land $ 54,385,560 Buildings 257,618,228 Site improvements 12,340,848 Construction in progress 1,467,090 Intangible assets 20,052,449 Investments in real estate joint ventures 17,495,254 Cash and cash equivalents, and restricted cash 7,763,490 Other assets 4,145,394 Total assets acquired $ 375,268,313 Liabilities assumed: Debt (1) $ 81,165,978 Accounts payable and other liabilities 8,074,162 Total liabilities assumed $ 89,240,140 Total net assets acquired $ 286,028,173 (1) Debt assumed includes approximately $ 40.5 million of debt on the KeyBank SST IV CMBS Loan, a $ 0.1 million fair market value discount on such debt, and the approximately $ 40.8 million SST IV TCF Loan. See Note 6 – Debt for additional information. Self Storage Facility Acquisitions On April 16, 2021, we purchased a self storage facility (the “Oakville III Property”) located in the Greater Toronto Area of Ontario, Canada. We acquired the Oakville III Property from an unaffiliated third party for a purchase price of approximately $ 25.0 million Canadian Dollars ("CAD"), plus closing costs. Upon acquisition, the property was approximately 42 % occupied. On May 27, 2021, we purchased a self storage facility located in Riverside, California (the “Riverside III Property”). The purchase price for the Riverside III Property was approximately $ 10.7 million, plus closing costs. Upon acquisition, the property was approximately 95 % occupied. On October 19, 2021 we purchased a self storage facility (the "Lakewood Property") located in the greater Denver, Colorado area. The purchase price for the Lakewood Property was approximately $ 17.5 million, plus closing costs. Upon acquisition, the property was approximately 91.3 % occupied.

If we fail to acquire the Chandler Property, in addition to the incurred acquisition costs, we may also forfeit earnest money as a result. We may assign certain of the above purchase and sale agreements in part or in full to one of our Managed REITs. Acquisition Completed by SST VI OP and Other SST VI OP Events On March 10, 2021, SmartStop OP made an investment of $ 5.0 million in SST VI OP, in exchange for common units of limited partnership interest in SST VI OP. On March 11, 2021, SST VI OP, through a wholly-owned subsidiary, used these funds, in part, to acquire its first self storage facility in Phoenix, Arizona for approximately $ 16 million. In connection with SST VI OP’s acquisition of the Phoenix property, we provided a $ 3.5 million mezzanine loan to a wholly-owned subsidiary of SST VI OP with an initial interest rate of 8.5 % and term of six months ; as well as a 180 day extension option which was exercised and increased the interest rate to 9.25 % for the remainder of the term. In addition to the mezzanine loan, SST VI financed the acquisition, in part, by obtaining a third party mortgage loan on the property of approximately $ 9 million. SST VI commenced its private offering in the first quarter of 2021. Given our level of ownership as of March 31, 2021, SST VI OP and its subsidiaries were consolidated in our financial statements, and all related intercompany transactions were eliminated. On April 16, 2021, in connection with SST VI OP’s investment in a real estate joint venture property located in North York, Ontario Canada, we provided an additional $ 2.1 million mezzanine loan with similar terms as the mezzanine loan discussed above. SST VI raised sufficient equity through its private offering such that, since May 1, 2021, we were no longer the primary beneficiary, and their operations are no longer consolidated by us. See Note 10 – Related Party Transactions for more information regarding our investments in SST VI and SST VI OP.

Equity Method Investments and Joint Ventures [Abstract]
Investments in Unconsolidated Real Estate Ventures	Note 4. Investments in Unconsolidated Real Estate Ventures As a result of the SST IV Merger, we acquired six self storage real estate joint ventures located in the Greater Toronto Area of Ontario, Canada. As of December 31, 2021, the real estate joint ventures consisted of five operating properties and one property under development. These joint venture agreements are with a subsidiary of SmartCentres, an unaffiliated third party, to acquire tracts of land and develop and operate the properties as self storage facilities. We account for these investments using the equity method of accounting and they are stated at cost and adjusted for our share of net earnings or losses and reduced by distributions. Equity in earnings (loss) will generally be recognized based on our ownership interest in the earnings (loss) of each of the unconsolidated investments. For the year ended December 31, 2021, we recorded an aggregate loss of approximately $ 0.5 million from our equity in earnings related to our unconsolidated real estate ventures in Canada. The following table summarizes our 50 % ownership interests in investments in unconsolidated real estate ventures in the Greater Toronto Area, Canada: Location Date Real Estate Venture Became Operational Carrying Value of Investment as of December 31, 2021 Oshawa August 2021 $ 1,801,413 East York June 2020 6,393,576 Brampton November 2020 2,354,346 Vaughan January 2021 2,871,265 Scarborough November 2021 2,862,677 Kingspoint Under Development 2,660,007 $ 18,943,284 Financing Agreement We, through our acquisition of the Oshawa, East York, Brampton, Vaughan, and Scarborough joint venture partnerships, also became party to a master mortgage commitment agreement (the “MMCA”) with SmartCentres Storage Finance LP (the “SmartCentres Lender”) (collectively, the “SmartCentres Financing”). The SmartCentres Lender is an affiliate of SmartCentres. The initial maximum amount available under the MMCA was approximately CAD $ 60 million, however, the SmartCentres Financing includes an accordion feature such that borrowings pursuant thereto may be increased up to approximately CAD $ 120 million subject to certain conditions set forth in the MMCA. On August 18, 2021, the Kingspoint property was added to the MMCA, increasing the available capacity to approximately CAD $ 68.5 million. As of December 31, 2021, approximately CAD $ 67.2 million was outstanding on the SmartCentres Financing. The proceeds of the SmartCentres Financing have been and will be used to finance the development and construction of the JV Properties. The SmartCentres Financing is secured by first mortgages on each of the JV Properties. The interest rate on the SmartCentres Financing is a variable annual rate equal to the aggregate of: (i) the BA Equivalent Rate (as defined in the MMCA), plus: (ii) a margin based on the External Credit Rating, plus (iii) a margin under the Senior Credit Facility, each as defined and described further in the MMCA. As of December 31, 2021, the total interest rate was approximately 2.64 %. The SmartCentres Financing had an original maturity date of May 11, 2021 . On April 30, 2021, the SmartCentres Financing was amended and the maturity date was extended until May 11, 2024 , and contains two one year extension options. Monthly interest payments are initially added to the outstanding principal balance. At such time as the JV Property is generating sufficient Net Cash Flow (as defined in the MMCA), the SmartCentres Financing provides for the commencement of quarterly payments of interest. As of December 31, 2021, no such payments had commenced. The borrowings advanced pursuant to the SmartCentres Financing may be prepaid without penalty, subject to certain conditions set forth in the MMCA. The SmartCentres Financing contains customary affirmative and negative covenants, agreements, representations, warranties and borrowing conditions (including a loan to value ratio of no greater than 70 % with respect to each JV Property) and events of default, all as set forth in the MMCA. We serve as a full recourse guarantor with respect to 50 % of the SmartCentres Financing.

Business Combinations [Abstract]
Self Administration Transaction	Note 5. Self Administration Transaction Overview On June 28, 2019, we, our Operating Partnership and our TRS entered into a series of transactions, agreements, and amendments to our existing agreements and arrangements with our then-sponsor SAM and SmartStop OP Holdings, LLC (“SS OP Holdings”), a subsidiary of SAM, pursuant to which, effective June 28, 2019, we acquired the self storage advisory, asset management and property management businesses and certain joint venture interests of SAM, along with certain other assets of SAM. As a result of the Self Administration Transaction, SAM is no longer our sponsor, and we became self-managed and succeeded to the advisory, asset management and property management businesses and certain joint ventures previously in place for us, SST IV (until the SST IV Merger Date), SSGT II, and we acquired the internal capability to originate, structure and manage additional future investment products which would be sponsored by SmartStop REIT Advisors, LLC (“SRA”), our indirect subsidiary. Agreements Contribution Agreement On June 28, 2019, we along with our Operating Partnership, as contributee, and SAM and SS OP Holdings, as contributor, entered into a Contribution Agreement (the “Contribution Agreement”) whereby the Operating Partnership acquired the Self Storage Platform and certain other assets, including (a) SAM’s, or its subsidiaries’, 100 % membership interests in our Former External Advisor and Former External Property Managers, the advisor and property manager for SST IV, the advisor and property manager for SSGT II, entities related to the Tenant Protection Programs joint ventures, and certain entities related to SAM’s self storage business in Canada; (b) all equipment, furnishings, fixtures and computer equipment as set forth in the Contribution Agreement; (c) certain personal property as set forth in the Contribution Agreement; (d) all intellectual property, goodwill, licenses and sublicenses granted and obtained with respect thereto (including all rights to the “SmartStop®” brand and “Strategic Storage®” related trademarks); (e) SAM’s processes, practices, procedures and workforce related to the self storage business (then consisting of a total of approximately 350 on-site self storage employees, regional and district managers, other personnel and the then current executive management team of the Company), and (f) certain other assets as set forth in the Contribution Agreement, in exchange for $ 769,126 in cash, assumption of existing debt in the amount of $ 15 million, and 8,698,956 Class A-1 limited partnership units of the Operating Partnership (“Class A-1 Units”) and 3,283,302 Class A-2 limited partnership units of the Operating Partnership (“Class A-2 Units”). For a description of the Class A-1 Units and Class A-2 Units, see below under the heading “Third Amended and Restated Limited Partnership Agreement and Redemption of Limited Partner Interest Agreement .” Third Amended and Restated Limited Partnership Agreement and Redemption of Limited Partner Interest Agreement On June 28, 2019, we entered into the Third Amended and Restated Limited Partnership Agreement of the Operating Partnership (as amended, the “Operating Partnership Agreement”), which amended and superseded the Second Amended and Restated Limited Partnership Agreement (the “Former OP Agreement”), and a Redemption of Limited Partner Interest Agreement (the “Redemption of Limited Partner Interest Agreement”) with the Former External Advisor and the Operating Partnership, pursuant to which the Operating Partnership redeemed all of the limited partnership interests held by the Former External Advisor in the Operating Partnership. As a result of the Redemption of Limited Partner Interest Agreement and the Self Administration Transaction, the Former External Advisor’s parent entity, SAM and its affiliates no longer hold either their previously existing 20,000 limited partnership units or their special limited partnership interest in the Operating Partnership; however, SAM received cash of $ 200,000 and Class A-1 Units and Class A-2 Units in the Operating Partnership, as further described below . In addition, the revised Operating Partnership Agreement created two new classes of units issued to SS OP Holdings in connection with the Self Administration Transaction: Class A-1 Units and Class A-2 Units. The Class A-1 Units are subject to the general restrictions on transfer contained in the Operating Partnership Agreement. In addition, through June 28, 2021 (the “Lock-Up Expiration”), the Class A-1 Units could not be sold, pledged, or otherwise transferred or encumbered except in certain limited circumstances set forth in the Contribution Agreement. The Class A-1 Units were and are now otherwise entitled to all rights and duties of the Class A limited partnership units in the Operating Partnership, including cash distributions and the allocation of any profits or losses in the Operating Partnership. The Class A-2 Units may convert into Class A-1 Units as earnout consideration, as described below. The Class A-2 Units are not entitled to cash distributions or the allocation of any profits or losses in the Operating Partnership until the Class A-2 Units are converted into Class A-1 Units . The conversion features of the Class A-2 Units are as follows: (A) the first time the aggregate incremental assets under management, as amended (“AUM”) (as defined in the Operating Partnership Agreement) of the Operating Partnership equals or exceeds $ 300,000,000 , one-third of the Class A-2 Units will automatically convert into Class A-1 Units, (B) the first time the incremental AUM of the Operating Partnership equals or exceeds $ 500,000,000 , an additional one-third of the Class A-2 Units will automatically convert into Class A-1 Units, and (C) the first time the incremental AUM equals or exceeds $ 700,000,000 , the remaining one-third of the Class A-2 Units will automatically convert into Class A-1 Units (each an “Earnout Achievement Date”). On each Earnout Achievement Date, the Class A-2 Units will automatically convert into Class A-1 Units based on an earnout exchange ratio, which is equal to $ 10.66 divided by the then current value of our Class A-1 Units, as provided in the Operating Partnership Agreement. On March 24, 2021, 1,094,434 Class A-2 Units held by SS OP Holdings were converted into 1,121,795 Class A-1 Units pursuant to the achievement of the first tier of earnout consideration . On October 19, 2021, the Nominating and Corporate Governance Committee of our board of directors and our board of directors approved resolutions providing that the denominator in the calculation of the earnout exchange ratio will be $ 10.66 (the value of the Class A common stock at the time of the Self Administration Transaction, pursuant to which the earnout was established) for the next 12 months, until October 19, 2022. Thereafter, the denominator in the calculation of the earnout exchange ratio will be as provided in the Operating Partnership Agreement . The Class A-2 Units conversion rights will expire seven years following the closing date of the Self Administration Transaction. Notwithstanding the foregoing, the earnout consideration will be earned and automatically convert in the event of an “Earnout Acceleration Event” (as defined in the Operating Partnership Agreement), which includes each of the following: certain change of control events (as described in the Operating Partnership Agreement), or H. Michael Schwartz being removed either as a member of our board of directors or as one of our executive officers for any reason other than cause. For additional information, see the Accounting Considerations Subsequent to Acquisition section further below. Fair Value of Consideration Transferred We accounted for the Contribution Agreement and Membership Interest Purchase Agreement discussed above as a business combination under the acquisition method of accounting. The estimated fair value of the consideration transferred totaled approximately $ 111.3 million and consisted of the following: Estimated Fair Value of Consideration Cash (1) $ 3,918,185 Class A-1 Units 63,643,000 Class A-2 Units (contingent earnout) 30,900,000 Total Consideration Transferred 98,461,185 Fair value of our preexisting 50 % equity interests 12,800,000 Total $ 111,261,185 (1) We assumed a net asset of approximately $ 0.5 million, which per the Contribution Agreement we were required to pay to SAM the value thereof and such amount was included above as cash consideration. As a result of this acquisition, we remeasured the book value of our preexisting 50 % equity method investments in our Tenant Protection Programs joint ventures to fair value, which resulted in a gain of approximately $ 8.0 million which was presented in the gain resulting from acquisition of unconsolidated affiliates line-item in our consolidated statements of operations as of the date of the acquisition. The estimated fair value of the contingent earnout, Class A-2 Units, was determined based on a discounted probability weighted forecast of achieving the requisite AUM thresholds. Subsequent to the completion of the Self Administration Transaction, such liability is required to be recorded at fair value. Allocation of Consideration The consideration transferred pursuant to the Self Administration Transaction was allocated to the assets acquired and liabilities assumed, based upon their estimated fair values as of the acquisition date. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed: Identifiable Assets Acquired at Fair Value Cash and cash equivalents $ 36,443 Restricted cash 94,999 Land 975,000 Building 5,389,000 Site Improvements 136,000 Equipment, furniture and fixtures 651,000 Investments in Managed REITs 5,600,000 Other assets 1,084,629 Intangibles - customer relationships 1,600,000 Trademarks 19,800,000 Intangibles - management contracts 24,900,000 Total identifiable assets acquired $ 60,267,071 Identifiable Liabilities Assumed at Fair Value Debt $ 19,219,126 Accounts payable and accrued expenses 722,286 Deferred tax liabilities, net 7,415,654 Total liabilities assumed $ 27,357,066 Net identifiable assets acquired $ 32,910,005 Goodwill 78,372,980 Non-controlling interest related to consolidated ( 21,800 ) Net assets acquired $ 111,261,185 The intangible assets acquired primarily consist of trademarks and the property management and advisory contracts related to the Managed REITs. The value of the property management and advisory contracts were determined based on a discounted cash flow valuation of the projected cash flows of the acquired contracts. The deferred tax liability is the result of differences between the GAAP carrying value of certain amortizing assets and the carrying value for tax purposes related to activities which are conducted through our TRS. Administrative Services Agreement On June 28, 2019, we along with our Operating Partnership, the TRS and SSA (collectively, the “Company Parties”) entered into an Administrative Services Agreement with SAM (the “Administrative Services Agreement”), which, as amended, requires that the Company Parties will be reimbursed for providing certain operational and administrative services to SAM which may include, without limitation, accounting and financial support, IT support, HR support, advisory services and operations support, and administrative support as set forth in the Administrative Services Agreement and SAM will be reimbursed for providing certain operational and administrative services to the Company Parties which may include, without limitation, due diligence support, marketing, fulfillment and offering support, events support, insurance support, and administrative and facilities support. SAM and the Company Parties will reimburse one another based on the actual costs of providing their respective services. Additionally, SAM will pay the Company Parties an allocation of rent and overhead for the portion it occupies in the Ladera Office. Such agreement has a term of three years (and is automatically renewed annually thereafter unless otherwise terminated no later than 90 days prior to the renewal term) and is subject to certain adjustments as defined in the agreement. Accounting Considerations Subsequent to Acquisition The emergence and spread of the COVID-19 pandemic caused significant volatility and disruption in the economy and the capital markets beginning in the first quarter of 2020. The increase in consumer and investor uncertainty had an impact on our Managed REITs, specifically the Managed REITs’ ability to attract investor equity in the face of economic weakness and volatility. The volatility and uncertainty in the economy caused various broker dealers that our Managed REITs had selling agreements with to temporarily halt non-traded REIT sales within their advisory networks. Effective April 30, 2020, the Managed REITs suspended their offerings. Given the disruption that COVID-19 had on the capital markets and our Managed REITs and their ability to raise additional equity, accordingly we evaluated the various intangible assets and liabilities associated with the sponsorship of the Managed REITs for impairment as of March 31, 2020. Based on the above facts, we revised our capital raise projections for the Managed REITs. We then evaluated the revised projected undiscounted future cash flows of our amortizing intangible assets to determine if they exceeded their respective carrying values and we determined that certain trademarks and management contracts acquired in the Self Administration Transaction were impaired. For such assets we recorded impairments to reduce their carrying value to their respective fair values. For our indefinite-lived trademark, we determined that the carrying value was in excess of its fair value and therefore recorded an impairment equal to the difference. As a result, we recorded impairment charges totaling approximately $ 11.7 million to intangible assets, consisting of approximately $ 3.3 million related to our trademarks, approximately $ 2.2 million related to the management contracts of SST IV and approximately $ 6.2 million related to the management contracts of SSGT II during the quarter ended March 31, 2020. We similarly evaluated goodwill for impairment and determined that the carrying value of the goodwill related to our Managed REIT segment was in excess of fair value, and therefore impaired and we recognized an impairment charge of approximately $ 24.7 million during the quarter ended March 31, 2020. Goodwill related to our self storage operations was not impaired. In connection with the Self Administration Transaction, we acquired a special limited partnership interest in SST IV and SSGT II. This interest, in certain situations, may entitle us to various subordinated distributions under SST IV’s and SSGT II’s operating partnership agreements. Given the revised capital projections noted above, the projected future subordinated distributions had revised estimated fair values less than their carrying values. We deemed this difference to be an other than temporary decline in value and therefore recorded an impairment charge of approximately $ 4.4 million during the quarter ended March 31, 2020 . As a result of the Self Administration Transaction, we recorded a deferred tax liability, which is the result of differences between the GAAP carrying value of certain amortizing assets and the carrying value for tax purposes of certain assets related to activities which are conducted through our TRS. As the impairment charge reduced the GAAP carrying value of such assets, primarily the Managed REIT management contracts, we adjusted the value of our deferred tax liabilities by pro-rata amounts, reducing the deferred tax liabilities in aggregate by approximately $ 2.4 million, and recorded such adjustment as other income within the other line-item in our consolidated statement of operations during the quarter ended March 31, 2020 . In connection with the Self Administration Transaction, we issued the Class A-2 Units, as a form of contingent consideration, which is required to be revalued at each reporting period, based on the discounted probability weighted forecast of achieving the requisite AUM thresholds or the occurrence of an Earnout Acceleration Event. The revised capital raise projections discussed above reduced the probability of the Class A-2 Units converting, which had the result of decreasing the estimated fair value of the contingent earnout liability from approximately $ 31.1 million as of December 31, 2019 to approximately $ 23.9 million as of the date of the impairment analysis . On March 24, 2021, we, as the general partner of our Operating Partnership, entered into Amendment No. 3 (the “Amendment”) to the Operating Partnership Agreement, to make certain revisions to the Operating Partnership Agreement. The Amendment (i) revised the definition of “AUM” in connection with the earnout of the Class A-2 Units so that it (A) includes assets acquired by us and our affiliates and (B) includes 100 % of any joint venture assets, rather than a pro rata percentage, and (ii) clarifies that the Class A-2 Units may be transferred after the two-year holding period. On March 24, 2021, 1,094,434 Class A-2 Units held by SS OP Holdings were converted into 1,121,795 Class A-1 Units pursuant to the achievement of the first tier of earnout consideration. The fair value of the contingent earnout liability was reduced as the Class A-2 Units were converted into Class A-1 Units in our Operating Partnership and the fair value of such units was reclassified to the noncontrolling interest in our Operating Partnership line in the equity section of our consolidated balance sheet. On October 19, 2021, the Nominating and Corporate Governance Committee of our board of directors and our board of directors approved resolutions providing that the denominator in the calculation of the earnout exchange ratio will be $ 10.66 (the value of the Class A common stock at the time of the Self Administration Transaction, pursuant to which the earnout was established) for the next 12 months, until October 19, 2022. Thereafter the denominator in the calculation of the earnout exchange ratio will be as provided in the Operating Partnership Agreement As of December 31, 2021, pursuant to the revised definition of “AUM” as described above, we had added incremental assets under management of approximately $ 472 million, and pursuant to the resolutions providing that the denominator in the calculation of the earnout exchange ratio will be $ 10.66 , the estimated fair value of the contingent earnout liability increased to approximately $ 30.0 million.

The amounts shown above are in USD based on the foreign exchange rate in effect as of December 31, 2020. (10) On March 17, 2021, these loans were paid off in full in conjunction with the SST IV Merger, and an aggregate net loss on extinguishment of debt of approximately $ 2.4 million was recorded. (11) The amounts shown above are in USD based on the foreign exchange rate in effect as of the date presented . (12) For additional information regarding the Credit Facility, see below. The weighted average interest rate on our consolidated debt, excluding the impact of our interest rate hedging activities, as of December 31, 2021 was approximately 3.02 %. We are subject to certain restrictive covenants relating to the outstanding debt. As of December 31, 2021, we were in compliance with all such covenants. Credit Facility On March 17, 2021, we, through our Operating Partnership (the “Borrower”), entered into a credit facility with KeyBank, National Association, as administrative agent, KeyBanc Capital Markets, LLC, Wells Fargo Securities, Citibank, N.A., and BMO Capital Markets, as joint book runners and joint lead arrangers, and certain other lenders party thereto (the “Credit Facility”). The initial aggregate amount of the Credit Facility was $ 500 million, which consisted of a $ 250 million revolving credit facility (the “Credit Facility Revolver”) and a $ 250 million term loan (the “Credit Facility Term Loan”). The Borrower had the right to increase the amount available under the Credit Facility by an additional $ 350 million (the “Accordion Feature”), for an aggregate amount of $ 850 million, subject to certain conditions. The Credit Facility also includes sublimits of (a) up to $ 25 million for letters of credit and (b) up to $ 25 million for swingline loans; each of these sublimits are part of, and not in addition to, the amounts available under the Credit Facility Revolver. Borrowings under the Credit Facility may be in either U.S. dollars (each, a “US Borrowing”) or Canadian dollars (each, a “CAD Borrowing”). Upon the closing of the Credit Facility, the Borrower immediately made the following drawdowns: (i) under the Credit Facility Revolver (A) $ 199 million in USD Borrowings and (B) CAD $ 2.5 million in CAD Borrowings (approximately $ 2 million equivalent in U.S. dollars), and (ii) under the Credit Facility Term Loan (A) $ 150 million in USD Borrowings and (B) CAD $ 124.7 million in CAD Borrowings (approximately $ 100 million equivalent in U.S. dollars), for an aggregate amount of approximately $ 451 million. We used the initial proceeds primarily to pay off certain existing indebtedness as well as indebtedness of SST IV in connection with the SST IV Merger. The maturity date of the Credit Facility Revolver is March 17, 2024 , subject to a one-year extension option. The maturity date of the Credit Facility Term Loan is March 17, 2026 , which can no t be extended. The Credit Facility may be prepaid or terminated at any time without penalty; provided, however, that the lenders shall be indemnified for certain breakage costs. Amounts borrowed under the Credit Facility Revolver and Credit Facility Term Loan bear interest based on both the type of borrowing (either ABR Loans or Eurodollar Loans, each as defined in the Credit Facility), as well as the currency of the borrowing. ABR Loans bear interest at the lesser of (x) the alternate base rate plus the applicable rate, or (y) the maximum rate. Eurodollar Loans bear interest at the lesser of (a) the adjusted LIBO rate or CDOR rate (depending on whether the loan is a US Borrowing or a CAD Borrowing, respectively) for the interest period in effect plus the applicable rate, or (b) the maximum rate. The corresponding applicable rate varies depending on the type of borrowing and our consolidated leverage ratio. As of December 31, 2021, advances under the Credit Facility Term Loan bear interest at 180 basis points over 30-day LIBOR or 30-day CDOR , while advances under the Credit Facility Revolver bear interest at 185 basis points over 30-day LIBOR or 30-day CDOR . The Credit Facility is also subject to an annual unused fee based upon the average amount of the unused portion of the Credit Facility Revolver, which varies from 15 bps to 25 bps, depending on the size of the unused amount, as well as whether a Security Interest Termination Event (defined below) has occurred. The Credit Facility is fully recourse, jointly and severally, to us, our Operating Partnership, and certain of our subsidiaries (the “Subsidiary Guarantors”). In connection with this, we, our Operating Partnership, and our Subsidiary Guarantors executed guarantees in favor of the lenders. The Credit Facility is also cross-defaulted to (i) any recourse debt of ours, our Operating Partnership, or the Subsidiary Guarantors and (ii) any non-recourse debt of ours, our Operating Partnership, or the Subsidiary Guarantors of at least $ 75 million. The Credit Facility is initially secured by a pledge of equity interests in the Subsidiary Guarantors. However, upon the achievement of certain security interest termination conditions, the pledges shall be released and the Credit Facility shall become unsecured (the “Security Interest Termination Event”). The Security Interest Termination Event occurs at the Borrower’s election, once the Borrower satisfies the following security interest termination conditions: (i) a fixed charge coverage ratio of no less than 1.50 :1.00; (ii) an unsecured interest coverage ratio of not less than 2.00 :1.00; (iii) a consolidated capitalization rate leverage ratio of not greater than 60 %; and (iv) a secured debt ratio of no greater than 40 %. Following the occurrence of the Security Interest Termination Event, certain terms and conditions of the Credit Facility are modified, including, but not limited to: (i) in certain circumstances, a reduction in the applicable interest rate under the Credit Facility, (ii) the modification or addition of certain financial covenants, (iii) the addition of a floor of at least $ 25 million for any cross-defaulted recourse debt of ours, our Operating Partnership, or any Subsidiary Guarantor, and (iv) in certain circumstances, a reduction in the annual unused fee for the Credit Facility Revolver. The Credit Facility contains certain customary representations and warranties, affirmative, negative and financial covenants, borrowing conditions, and events of default. In particular, the financial covenants imposed include: a maximum leverage ratio, a minimum fixed charge coverage ratio, a minimum tangible net worth, certain limits on both secured debt and secured recourse debt, certain payout ratios of dividends paid to core funds from operations, limits on unhedged variable rate debt, and minimum liquidity. If an event of default occurs and continues, the Borrower is subject to certain actions by the administrative agent, including, without limitation, the acceleration of repayment of all amounts outstanding under the Credit Facility. On May 3, 2021, we converted all of our CAD Borrowings to USD Borrowings. On October 7, 2021, the Borrower and lenders who were party to the Credit Facility amended the Credit Facility to increase the commitment on the Credit Facility Revolver by $ 200 million for a total commitment of $ 450 million. In connection with the increased commitments, additional lenders were added to the Credit Facility. The commitments on the Credit Facility Term Loan remain unchanged. As a result of this amendment, the aggregate commitment on the Credit Facility is now $ 700 million. In addition, the Accordion Feature was also amended such that Borrower has the right to increase the aggregate amount of the Credit Facility by an additional $ 350 million, for an aggregate amount of up to $ 1.05 billion, subject to certain conditions. As of December 31, 2021, the Borrower has borrowed approximately $ 233 million of the $ 450 million current capacity of the Credit Facility Revolver and all $ 250 million of the $ 250 million current capacity of the Credit Facility Term Loan. SST IV CMBS Loan On March 17, 2021, in connection with the SST IV Merger, we assumed a $ 40.5 million CMBS financing with KeyBank as the initial lender pursuant to a mortgage loan (the “SST IV CMBS Loan”). The SST IV CMBS Loan is secured by a first mortgage or deed of trust on each of seven properties owned by us (Jensen Beach, Texas City, Riverside, Las Vegas IV, Puyallup, Las Vegas V, and Plant City). The separate assets of these encumbered properties are not available to pay our other debt. The loan has a maturity date of February 1, 2030 . Monthly payments due under the loan agreement (the “SST IV CMBS Loan Agreement”) are interest-only, with the full principal amount becoming due and payable on the maturity date. The amounts outstanding under the SST IV CMBS Loan bear interest at an annual fixed rate equal to 3.56 %. Commencing two years after securitization, the CMBS Loan may be defeased in whole, but not in part, subject to certain conditions as set forth in the SST IV CMBS Loan Agreement. The loan documents for the SST IV CMBS Loan contain: customary affirmative and negative covenants; agreements; representations; warranties and borrowing conditions; reserve requirements and events of default all as set forth in such loan documents. In addition, and pursuant to the terms of the limited recourse guaranty in favor of KeyBank, we serve as a non- recourse guarantor with respect to the SST IV CMBS Loan. SST IV TCF Loan On March 17, 2021, in connection with the SST IV Merger, we assumed a term loan with TCF National Bank, a national banking association (“TCF”), as lead arranger and administrative agent for up to $ 40.8 million (the “SST IV TCF Loan”). The SST IV TCF Loan is secured by a first mortgage on each of the Ocoee Property, the Ardrey Kell Property, the Surprise Property, the Escondido Property, and the Punta Gorda Property (the “SST IV TCF Properties”). The interest rate on the SST IV TCF Loan is equal to the greater of (i) 3.75 % per annum or (ii) an adjustable annual rate equal to LIBOR plus 3.00 % . Upon achievement of certain financial conditions, the interest rate will be equal to the greater of (i) 3.50 % per annum or (ii) an adjustable annual rate equal to LIBOR plus 2.50 % . As of December 31, 2021, the interest rate on the SST IV TCF Loan was 3.75 %. In connection with the SST IV Merger, we also assumed an interest rate cap with a notional amount of $ 30.5 million, such that in no event will LIBOR exceed 0.75 % thereon through May 2022. The SST IV TCF Loan matures on March 30, 2023 , with two one-year extension options subject to certain conditions outlined further in the SST IV TCF Loan documents. During the initial term, monthly payments are interest only; during any extension periods, monthly payments are principal and interest. The SST IV TCF Loan may be prepaid in whole or in part, subject to certain conditions as set forth in the SST IV TCF loan agreement. The SST IV TCF loan agreement also contains a debt service coverage ratio covenant applicable to the borrowers whereby, commencing on March 31, 2022, the SST IV TCF Properties must have a debt service coverage ratio of not less than 1.20 to 1.00. The SST IV TCF loan agreement also contains: customary affirmative, negative and financial covenants; agreements; representations; warranties and borrowing conditions; and events of default all as set forth in such loan agreement. We serve as a limited recourse guarantor with respect to the SST IV TCF Loan during the initial term. Our obligations as guarantor may decrease based on the debt service coverage ratio on the SST IV TCF Properties. Oakville III BMO Loan On April 15, 2021, we purchased the Oakville III Property. We partially financed the Oakville III property acquisition with a loan from Bank of Montreal (the “Oakville III BMO Loan”), which is secured by a first lien on the Oakville III property. The loan is denominated in Canadian dollars and the proceeds from the loan were approximately CAD $ 16.3 million. We provided a full recourse guaranty on the loan, which will remain in effect until the property achieves 75% physical occupancy, at which point such guaranty will be reduced to 50% of the loan balance. The interest only loan is prepayable at any time without penalty, and bears interest at a rate of 2.25 % + CDOR. The Oakville III BMO Loan contains customary affirmative and negative covenants, agreements, representations, warranties and borrowing conditions. The following table presents the future principal payment requirements on outstanding debt as of December 31, 2021: 2022 $ 2,914,434 2023 44,166,662 2024 293,039,610 2025 2,869,188 2026 341,916,098 2027 and thereafter 192,605,555 Total payments 877,511,547 Premium on secured debt, net 234,604 Debt issuance costs, net ( 3,879,296 ) Total $ 873,866,855

Equity [Abstract]
Preferred Equity	Note 7. Preferred Equity Series A Convertible Preferred Stock On October 29, 2019 (the “Commitment Date”), we entered into a preferred stock purchase agreement (the “Purchase Agreement”) with Extra Space Storage LP (the “Investor”), a subsidiary of Extra Space Storage Inc. (NYSE: EXR), pursuant to which the Investor committed to purchase up to $ 200 million in preferred shares (the aggregate shares to be purchased, the “Preferred Shares”) of our new Series A Convertible Preferred Stock (the “Series A Convertible Preferred Stock”), in one or more closings (each, a “Closing,” and collectively, the “Closings”). The initial closing (the “Initial Closing”) in the amount of $ 150 million occurred on the Commitment Date, and the second and final closing in the amount of $ 50 million occurred on October 26, 2020. We incurred approximately $ 3.6 million in issuance costs related to the Series A Convertible Preferred Stock, which were recorded as a reduction to Series A Convertible Preferred stock on our consolidated balance sheets. The shares of Series A Convertible Preferred Stock rank senior to all other shares of our capital stock, including our common stock, with respect to rights to receive dividends and to participate in distributions or payments upon any voluntary or involuntary liquidation, dissolution or winding up of the Company. Dividends payable on each share of Series A Convertible Preferred Stock will initially be equal to a rate of 6.25 % per annum. If the Series A Convertible Preferred Stock has not been redeemed on or prior to the fifth anniversary date of the Initial Closing, the dividend rate will increase an additional 0.75% per annum each year thereafter to a maximum of 9.0% per annum until the tenth anniversary of the Initial Closing, at which time the dividend rate shall increase 0.75% per annum each year thereafter until the Series A Convertible Preferred Stock is redeemed or repurchased in full. The dividends are payable in arrears for the prior calendar quarter on or before the 15 th day of March, June, September and December of each year. Upon any voluntary or involuntary liquidation, dissolution or winding up of the Company, the holders of Series A Convertible Preferred Stock will be entitled to receive a payment equal to the greater of (i) aggregate purchase price of all outstanding Preferred Shares, plus any accrued and unpaid dividends (the “Liquidation Amount”) and (ii) the amount that would have been payable had the Preferred Shares been converted into common stock pursuant to the terms of the Purchase Agreement immediately prior to such liquidation. Subject to certain additional redemption rights, as described herein, we have the right to redeem the Series A Convertible Preferred Stock for cash at any time following the fifth anniversary of the Initial Closing. The amount of such redemption will be equal to the Liquidation Amount. Upon the listing of our common stock on a national securities exchange (the “Listing”), we have the right to redeem any or all outstanding Series A Convertible Preferred Stock at an amount equal to the greater of (i) the amount that would have been payable had such Preferred Shares been converted into common stock pursuant to the terms of the Purchase Agreement immediately prior to the Listing, and then all of such Preferred Shares were sold in the Listing, or (ii) the Liquidation Amount, plus a premium amount (the “Premium Amount”) of 10 %, 8 %, 6 %, 4 %, or 2 % if redeemed prior to the first, second, third, fourth, or fifth anniversary dates of issuance, respectively, or 0 % if redeemed thereafter, as set forth in the Articles Supplementary. Upon a change of control event, we have the right to redeem any or all outstanding Series A Convertible Preferred Stock at an amount equal to the greater of (i) the amount that would have been payable had the Preferred Shares been converted into common stock pursuant to the terms of the Purchase Agreement immediately prior to such change of control or (ii) the Liquidation Amount, plus the Premium Amount, as set forth in the Articles Supplementary. In addition, subject to certain cure provisions, if we fail to maintain our status as a real estate investment trust, the holders of Series A Convertible Preferred Stock have the right to require us to repurchase the Series A Convertible Preferred Stock at an amount equal to the Liquidation Amount with no Premium Amount. Subject to our redemption rights in the event of a Listing or change of control described above, upon the earlier to occur of (i) the second anniversary of the Initial Closing or (ii) 180 days after a Listing, the holders of Series A Convertible Preferred Stock have the right to convert any or all of the Series A Convertible Preferred Stock held by such holders into common stock at a rate per share equal to the quotient obtained by dividing the Liquidation Amount by the conversion price. The conversion price is $ 10.66 , as may be adjusted in connection with stock splits, stock dividends and other similar transactions. The holders of Series A Convertible Preferred Stock are not entitled to vote on any matter submitted to a vote of our stockholders, except that in the event that the dividend for the Series A Convertible Preferred Stock has not been paid for at least four quarters (whether or not consecutive), the holders of Series A Convertible Preferred Stock have the right to vote together with our stockholders on any matter submitted to a vote of our stockholders, upon which the holders of the Series A Convertible Preferred Stock and holders of common stock shall vote together as a single class. The number of votes applicable to a share of Series A Convertible Preferred Stock will be equal to the number of shares of common stock a share of Series A Convertible Preferred Stock could have been converted into as of the record date set for purposes of such stockholder vote. This foregoing limited voting right shall cease when all past dividend periods have been paid in full. In addition, the affirmative vote of the holders of a majority of the outstanding shares of Series A Convertible Preferred Stock is required in certain customary circumstances, as well as other circumstances, such as (i) our real estate portfolio exceeding a leverage ratio of 60 % loan-to-value, (ii) entering into certain transactions with our Executive Chairman as of the Commitment Date, or his affiliates, (iii) effecting a merger (or similar) transaction with an entity whose assets are not at least 80 % self storage related and (iv) entering into any line of business other than self storage and ancillary businesses, unless such ancillary business represents revenues of less than 10 % of our revenues for our last fiscal year. In connection with the issuance of the Series A Convertible Preferred Stock, we and the Investor also entered into an investors’ rights agreement (the “Investors’ Rights Agreement”) which provides the Investor with certain customary protections, including demand registration rights and “piggyback” registration rights with respect to our common stock issued to the Investor upon conversion of the Preferred Shares. As of December 31, 2021, there were 200,000 Preferred Shares outstanding with an aggregate liquidation preference of approximately $ 203.2 million, which consists of $ 150 million from the Initial Closing, $ 50 million from a closing on October 26, 2020 and approximately $ 3.2 million of accumulated and unpaid distributions. As of December 31, 2020, there were 200,000 Preferred Shares outstanding with an aggregate liquidation preference of approximately $ 202.9 million, which consisted of $ 150 million from the Initial Closing, $ 50 million from a closing on October 26, 2020 and approximately $ 2.9 million of accumulated and unpaid distributions.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments	Note 8. Derivative Instruments Interest Rate Derivatives Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements. To accomplish this objective, we use interest rate swaps and caps as part of our interest rate risk management strategy. The effective portion of the change in the fair value of the derivative that qualifies as a cash flow hedge is recorded in accumulated other comprehensive income (loss) (“AOCI”) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Amounts reported in AOCI related to derivatives will be reclassified to interest expense as interest payments are made on our variable rate debt. We do not use interest rate derivatives for trading or speculative purposes. Derivatives not designated as hedges are not speculative and are used to manage our exposure to interest rate movements and other identified risks but we have elected not to apply hedge accounting. Changes in the fair value of interest rate derivatives not designated in hedging relationships are recorded in other income (expense) as income within our consolidated statements of operations. Foreign Currency Hedges Our objectives in using foreign currency derivatives are to add stability to potential fluctuations in exchange rates between foreign currencies and the U.S. dollar and to manage our exposure to exchange rate movements. To accomplish this objective, we use foreign currency forwards and foreign currency options as part of our exchange rate risk management strategy. A foreign currency forward contract is a commitment to deliver a certain amount of currency at a certain price on a specific date in the future. By entering into the forward contract and holding it to maturity, we are locked into a future currency exchange rate in an amount equal to and for the term of the forward contract. A foreign currency option contract is a commitment by the seller of the option to deliver, solely at the option of the buyer, a certain amount of currency at a certain price on a specific date. For derivatives designated as net investment hedges, the changes in the fair value of the derivatives are reported in accumulated other comprehensive income. Amounts are reclassified out of accumulated other comprehensive income (loss) into earnings when the hedged net investment is either sold or substantially liquidated. The following table summarizes the terms of our derivative financial instruments as of December 31, 2021: Notional Strike Effective Date or Maturity Date Interest Rate Swap: LIBOR Swap $ 235,000,000 1.79 % June 15, 2019 February 15, 2022 Foreign Currency Forwards: Denominated in CAD $ 125,925,000 (1) 1.2593 April 12, 2021 April 12, 2023 Denominated in CAD 122,020,000 (1) 1.2202 May 6, 2021 April 12, 2022 (1) Notional amounts shown are denominated in CAD. On February 10, 2020, we settled an existing CAD currency forward, receiving a net settlement of approximately $ 0.5 million and simultaneously entered into a one year CAD $ 95 million foreign currency forward. On February 10, 2021, we rolled this currency forward into a two month CAD $ 95 million foreign currency forward, with a settlement date of April 12, 2021. On April 12, 2021, we settled this foreign currency forward, paying a net settlement of approximately $ 4.5 million, and simultaneously entered into a new CAD $ 125.9 million currency forward with a settlement date of April 12, 2023 . On May 6, 2021, we entered into a second currency forward, for approximately CAD $ 122 million, with a settlement date of April 12, 2022 .

Segment Reporting [Abstract]
Segment Disclosures	Note 9. Segment Disclosures Prior to the Self Administration Transaction on June 28, 2019, we internally evaluated all of our properties and interests therein as one industry segment and, accordingly, did not report segment information. Subsequent to the Self Administration Transaction, we now operate in two reportable business segments: (i) self storage operations and (ii) our Managed REIT Platform business. Management evaluates performance based upon property net operating income (“NOI”). For our self storage operations, NOI is defined as leasing and related revenues, less property level operating expenses. NOI for the Company’s Managed REIT Platform business represents Managed REIT Platform revenues less Managed REIT Platform expenses. The following tables summarize information for the reportable segments for the periods presented: Year Ended December 31, 2021 Managed REIT Corporate Self Storage Platform and Other Total Revenues:

The following table summarizes our total assets by segment: Segments December 31, 2021 December 31, 2020 Self Storage (1) $ 1,546,835,094 $ 1,172,178,148 Managed REIT Platform (2) 21,707,326 44,482,625 Corporate and Other 49,750,356 65,560,284 Total assets (3) $ 1,618,292,776 $ 1,282,221,057 (1) Included in the assets of the Self Storage segment as of December 31, 2021 and 2020 are approximately $ 49.8 million and $ 45.3 million of goodwill, respectively. Additionally, as of December 31, 2021 and 2020, t here were no accumulated impairment charges to goodwill within the Self Storage segment. The increase in goodwill in the Self Storage segment during the year ended December 31, 2021 was the result of a reallocation of goodwill due to the SST IV Merger. (2) Included in the assets of the Managed REIT Platform segment as of December 31, 2021 and 2020, are approximately $ 3.9 million and $ 8.4 million of goodwill, respectively. Such goodwill is net of accumulated impairment charges in the Managed REIT Platform segment of approximately $ 24.7 million as of December 31, 2021 and 2020, which relates to the impairment charge recorded during the quarter ended March 31, 2020. See Note 5 – Self Administration Transaction, for further information regarding our goodwill and intangible asset impairment charges within the Managed REIT Platform segment. The decrease in goodwill in the Managed REIT Platform segment during the year ended December 31, 2021 was the result of a reallocation of goodwill due to the SST IV Merger. (3) Other than our investments in and advances to Managed REITs, substantially all of our investments in real estate facilities and intangible assets made during the years ended December 31, 2021 and 2020 were associated with our self storage platform.

Related Party Transactions [Abstract]
Related Party Transactions	Note 10. Related Party Transactions Through the closing of the Self Administration Transaction on June 28, 2019, we incurred expenses under the following advisory and property management agreements; commencing on such closing and continuing thereafter we no longer incur such expenses. The Former Dealer Manager Agreement and the Transfer Agent Agreement described below were not impacted by the Self Administration Transaction. Former Dealer Manager Agreement In connection with our Primary Offering, our Former Dealer Manager received a sales commission of up to 7.0 % of gross proceeds from sales of Class A Shares and up to 2.0 % of gross proceeds from the sales of Class T Shares in the Primary Offering and a dealer manager fee up to 3.0 % of gross proceeds from sales of both Class A Shares and Class T Shares in the Primary Offering under the terms of the Former Dealer Manager Agreement. In addition, our Former Dealer Manager receives an ongoing stockholder servicing fee as discussed in Note 2 – Summary of Significant Accounting Policies – Organization and Offering Costs. Affiliated Former Dealer Manager SAM owns a 15 % non-voting equity interest in our Former Dealer Manager. Affiliates of our Former Dealer Manager own limited partnership interests in our Operating Partnership. Transfer Agent Agreement SAM owns 100 % of the membership interests of Strategic Transfer Agent Services, LLC, our transfer agent (“Transfer Agent”), which is a registered transfer agent with the SEC. Pursuant to our transfer agent agreement, our Transfer Agent provides transfer agent and registrar services to us. These services are substantially similar to what a third party transfer agent would provide in the ordinary course of performing its functions as a transfer agent, including, but not limited to: providing customer service to our stockholders, processing the distributions and any servicing fees with respect to our shares and issuing regular reports to our stockholder. Our Transfer Agent may retain and supervise third party vendors in its efforts to administer certain services. We believe that our Transfer Agent, through its knowledge and understanding of the direct participation program industry which includes non-traded REITs, is particularly suited to provide us with transfer agent and registrar services. Our Transfer Agent also conducts transfer agent and registrar services for other non-traded REITs sponsored by SRA. Fees paid to our Transfer Agent include a fixed quarterly fee, one-time account setup fees, monthly open account fees and fees for investor inquiries. In addition, we will reimburse our Transfer Agent for all reasonable expenses or other changes incurred by it in connection with the provision of its services to us, and we will pay our Transfer Agent fees for any additional services we may request from time to time, in accordance with its rates then in effect. Upon the request of our Transfer Agent, we may also advance payment for substantial reasonable out-of-pocket expenditures to be incurred by it. The initial term of the transfer agent agreement is three years , which term will be automatically renewed for one year successive terms, but either party may terminate the transfer agent agreement upon 90 days’ prior written notice. In the event that we terminate the transfer agent agreement, other than for cause, we will pay our transfer agent all amounts that would have otherwise accrued during the remaining term of the transfer agent agreement; provided, however, that when calculating the remaining months in the term for such purposes, such term is deemed to be a 12 month period starting from the date of the most recent annual anniversary date. Pursuant to the terms of the agreements described above, the following table summarizes related party costs incurred and paid by us for the years ended December 31, 2020 and 2021, as well as any related amounts payable as of December 31, 2020 and 2021.

The amount incurred during the year ended December 31, 2021 represents an adjustment to the estimated stockholder servicing fee recorded at the time of the sale of the Class T Shares, based on the current estimated cessation date (March 31, 2022) of such stockholder servicing fee. (2) Represents the stockholder servicing fee liability assumed in the SST IV Merger. Please see Note 3 – Real Estate Facilities and Note 5 – Self Administration Transaction for additional information. Acquisition of Self Storage Platform from SmartStop Asset Management, LLC and Other Transactions As a result of the Self Administration Transaction, we acquired the self storage sponsorship platform of SAM. Accordingly, the advisor and property manager entities of SST IV and SSGT II became our indirect subsidiaries, and we became entitled to receive various fees and expense reimbursements under the terms of the SST IV and SSGT II advisory and property management agreements as described below. In addition, we also own the advisor and property manager entities of SST VI and are entitled to receive various fees and expense reimbursements under the terms of the SST VI advisory and property management agreements as described below. Advisory Agreement Fees Our indirect subsidiaries, Strategic Storage Advisor IV, LLC, the advisor to SST IV (the “SST IV Advisor”), SS Growth Advisor II, LLC, the advisor to SSGT II (the “SSGT II Advisor”), and Strategic Storage Advisor VI, LLC, the advisor to SST VI (the “SST VI Advisor”) are or were entitled to receive various fees and expense reimbursements under the terms of the SST IV, SSGT II, and SST VI advisory agreements. SST IV Advisory Agreement The SST IV Advisor provided acquisition and advisory services to SST IV pursuant to an advisory agreement (the “SST IV Advisory Agreement”) to SST IV up until the SST IV Merger on March 17, 2021. Effective April 30, 2020, SST IV suspended its offering due to various factors, including the uncertainty relating to the ongoing COVID-19 outbreak and its potential economic impact, the status of fundraising in the non-traded REIT industry due to such uncertainty and the termination of their dealer manager agreement. SST IV’s public offering terminated on September 11, 2020. The SST IV Advisor received a monthly asset management fee equal to 0.0833 %, which is one-twelfth of 1% , of SST IV’s aggregate asset value, as defined. The SST IV Advisor was potentially also entitled to various subordinated distributions under SST IV’s operating partnership agreement pursuant to the special limited partnership interest and its cash flow participation distribution rights if SST IV (1) listed its shares of common stock on a national exchange, (2) terminated the SST IV Advisory Agreement, (3) liquidated its portfolio, or (4) entered into an Extraordinary Transaction, as defined in the SST IV operating partnership agreement. Effective March 17, 2021, in connection with the SST IV Merger, the SST IV Advisory Agreement was terminated and none of the aforementioned subordinated distributions or fees were paid. As a result of us acquiring SST IV and terminating such contracts, we recorded a write-off of approximately $ 5.3 million related to the carrying value of the SST IV Advisory Agreement contract. Similarly, we recorded a write-off of approximately $ 1.2 million related to our special limited partnership interest, which per the terms of the SST IV Merger Agreement, terminated without consideration . As a result of the Self Administration Transaction, we recorded a deferred tax liability, which was the result of the difference between the GAAP carrying value of the SST IV Advisory Agreement and its carrying value for tax purposes. As we reduced the GAAP carrying value of such intangible asset, as noted above, we adjusted the value of our deferred tax liabilities by pro-rata amounts, reducing the deferred tax liabilities in aggregate by approximately $ 1.4 million during the year ended December 31, 2021, and recorded such adjustment as Other income within the other line item in our consolidated statements of operations . SSGT II Advisory Agreement The SSGT II Advisor provides acquisition and advisory services to SSGT II pursuant to an advisory agreement (the “SSGT II Advisory Agreement”). In connection with the SSGT II private placement offering, SSGT II is required to reimburse the SSGT II Advisor for organization and offering costs from the SSGT II private offering pursuant to the SSGT II Advisory Agreement. Effective as of April 30, 2020, SSGT II suspended its offering due to various factors, including the uncertainty relating to the ongoing COVID-19 outbreak and its potential economic impact, the status of fundraising in the non-traded REIT industry due to such uncertainty and the termination of its dealer manager agreement. The SSGT II Advisor receives a monthly asset management fee equal to 0.1042 %, which is one-twelfth of 1.25% , of SSGT II’s aggregate asset value, as defined. The SSGT II Advisor may also be potentially entitled to various subordinated distributions under SSGT II’s operating partnership agreement pursuant to the special limited partnership interest and its cash flow participation distribution rights. So long as the SSGT II Advisory Agreement has not been terminated (including by means of non-renewal), SSGT II is required to pay the SSGT II Advisor a distribution from its operating partnership (other than net sale proceeds), pursuant to a special limited partnership interest, equal to 10.0 % of any amount distributed to stockholders in excess of the amount required to provide stockholders with an annual aggregate distribution equal to 5.0 % (reflective of the weighted average purchase price per share), cumulative within the subject calendar year (as adjusted for partial periods outstanding). Such distribution will be reconciled and paid annually. The cash flow participation distribution may be payable in cash or operating partnership units (or any combination thereof), at the election of the SSGT II Advisor . Pursuant to SSGT II’s operating partnership agreement if SSGT II (1) lists its shares of common stock on a national exchange, (2) terminates the SSGT II Advisory Agreement, (3) liquidates its portfolio, or (4) merges with another entity or enters into an Extraordinary Transaction, as defined in the SSGT II operating partnership agreement, the SSGT II Advisor may potentially be entitled to various subordinated distributions. The SSGT II Advisory Agreement provides for reimbursement of the SSGT II Advisor’s direct and indirect costs of providing administrative and management services to SSGT II. SST VI Advisory Agreement The SST VI Advisor provides acquisition and advisory services to SST VI pursuant to an advisory agreement (the “SST VI Advisory Agreement”). In connection with the SST VI private placement offering, SST VI is required to reimburse the SST VI Advisor for organization and offering costs from the SST VI private offering pursuant to the SST VI Advisory Agreement. Pursuant to the SST VI Advisory Agreement, the SST VI Advisor will receive acquisition fees equal to 1.00 % of the contract purchase price of each property SST VI acquires plus reimbursement of any acquisition expenses that SST VI Advisor incurs. The SST VI Advisor also receives a monthly asset management fee equal to 0.0625 %, which is one-twelfth of 0.75% , of SST VI’s aggregate asset value, as defined. The SST VI Advisor may also be potentially entitled to various subordinated distributions pursuant to the special limited partnership interest under SST VI’s operating partnership agreement if SST VI (1) lists its shares of common stock on a national exchange, (2) terminates the SST VI Advisory Agreement, (3) liquidates its portfolio, or (4) merges with another entity or enters into an Extraordinary Transaction, as defined in the SST VI operating partnership agreement. The SST VI Advisory Agreement provides for reimbursement of the SST VI Advisor’s direct and indirect costs of providing administrative and management services to SST VI. Managed REIT Property Management Agreements Our indirect subsidiaries, Strategic Storage Property Management IV, LLC, SS Growth Property Management II, LLC, and Strategic Storage Property Management VI, LLC (collectively the “Managed REITs Property Managers”), are entitled to receive fees for their services in managing the properties owned by the Managed REITs pursuant to property management agreements entered into between the owner of the property and the applicable Managed REIT’s Property Manager. The Managed REITs’ Property Managers will receive a property management fee equal to 6 % of the gross revenues from the properties, generally subject to a monthly minimum of $ 3,000 per property, plus reimbursement of the costs of managing the properties, and a one-time fee of $ 3,750 for each property acquired that would be managed by the Managed REITs’ Property Managers. Reimbursable costs and expenses include wages and salaries and other expenses of employees engaged in operating, managing and maintaining such properties. Pursuant to the property management agreements, we through our Operating Partnership employ the on-site staff for the Managed REITs’ properties. The SST IV and SST VI property managers are or were entitled to a construction management fee equal to 5 % of the cost of a related construction or capital improvement work project in excess of $ 10,000 . Effective March 17, 2021, in connection with the SST IV Merger, the SST IV property management contracts were terminated. As a result of us acquiring SST IV and terminating such contracts, we recorded a write-off of approximately $ 1.9 million related to the carrying value of the SST IV property management contracts. In connection with the Self Administration Transaction, we previously recorded a deferred tax liability, which is the result of the difference between the GAAP carrying value of the SST IV property management contracts and their carrying value for tax purposes. As we reduced the GAAP carrying value of such intangible assets, we adjusted the value of our deferred tax liabilities by pro-rata amounts, reducing the deferred tax liabilities in aggregate by approximately $ 0.5 million, and recorded such adjustment as other income within the other line-item in our consolidated statement of operations. Summary of Fees and Revenue Related to the Managed REITs Pursuant to the terms of the various agreements described above for the Managed REITs, the following summarizes the related party fees for the years ended December 31, 2021, 2020, and 2019: Managed REIT Platform Revenues Year Ended Year Ended Year Ended Advisory agreement – SST IV (1) $ 716,278 $ 3,211,661 $ 1,153,137 Advisory agreement – SSGT II 1,843,769 1,210,529 310,786 Advisory agreement – SST VI 178,282 - - Property management agreement – SST IV (1) 346,179 1,429,632 602,162 Property management agreement – SSGT II 709,533 371,751 91,594 Property management agreement – SST VI 99,602 - - Tenant Protection Program revenue – SST IV (3) 285,959 893,315 - Tenant Protection Program revenue – SSGT II 636,671 257,602 37,269 Tenant Protection Program revenue – SST VI 158,662 - 254,148 Other Managed REIT revenue (2) 1,348,035 674,140 619,210 Total $ 6,322,970 $ 8,048,630 $ 3,068,306 (1) On March 17, 2021, we acquired SST IV and no longer earn such fees. (2) Such revenues primarily include construction management, development fees, and other miscellaneous revenues. (3) On March 17, 2021, we acquired SST IV and such revenue is now included in ancillary operating revenue in our consolidated statements of operations. Reimbursable costs from Managed REITs includes reimbursement of SST IV (until the SST IV Merger Date), SSGT II, and SST VI Advisors’ direct and indirect costs of providing administrative and management services to the Managed REITs. Additionally, reimbursable costs includes reimbursement pursuant to the property management agreements for reimbursement of the costs of managing the Managed REITs’ properties, including wages and salaries and other expenses of employees engaged in operating, managing and maintaining such properties. As of December 31, 2021 and 2020, we had receivables due from the Managed REITs totaling approximately $ 1.4 million, and $ 0.5 million, respectively. Such amounts are included in investments in and advances to the Managed REITs line-item in our consolidated balance sheets. Such amounts included unpaid amounts relative to the above table, in addition to other direct routine expenditures of the Managed REITs that we directly funded. Investment in SSGT II OP On September 21, 2020, a wholly-owned subsidiary of our Operating Partnership (the “Preferred Investor”), entered into a preferred unit purchase agreement (the “SSGT II Unit Purchase Agreement”) with SS Growth Operating Partnership II, L.P. (the “SSGT II OP”) and SSGT II. Pursuant to the terms of the SSGT II Unit Purchase Agreement, the Preferred Investor agreed to purchase, in one or more tranches, up to 1.6 million units of limited partnership interest in SSGT II OP (the “SSGT II Preferred Units”) for an aggregate of up to $ 40 million (the “SSGT II Investment”). Upon the closing of each tranche of the SSGT II Investment, the Preferred Investor was due an investment fee equal to 1 % of the investment amount of such tranche . The Preferred Investor received distributions, payable monthly in arrears, at a rate of 7.25 % per annum from the date of investment until 180 days after the date of investment, 8.25 % per annum from 181 days after the date of investment until 360 days after the date of investment, and 9.25 % per annum thereafter (collectively, the “Pay Rate”). The proceeds of the SSGT II Investment may be used by SSGT II OP to finance self storage acquisition, development, and improvement activities, and working capital or other general partnership purposes. Each SSGT II Preferred Unit had a liquidation preference of $ 25.00 , plus all accumulated and unpaid distributions. The foregoing distributions are payable monthly, and calculated on an actual/360 day basis, and any unpaid distributions accrue at the applicable Pay Rate. On September 21, 2020, October 29, 2020, and November 4, 2020, the Preferred Investor invested approximately $ 6.5 million, $ 13 million, and $ 13 million, respectively, in the SSGT II Operating Partnership. On November 12, 2020, SSGT II redeemed $ 19 million of our SSGT II Preferred Units, reducing our investment in SSGT II Preferred Units to $ 13.5 million, which was recorded in investments in and advances to Managed REITs in our consolidated balance sheets as of December 31, 2020. On January 21, 2021, SSGT II redeemed the remaining $ 13.5 million of our outstanding SSGT II Preferred Units. As of December 31, 2021 and 2020, we were potentially required to purchase an additional $ 7.5 million in SSGT II Preferred Units. For the years ended December 31, 2021 and 2020, we recorded income related to the SSGT II Preferred Units totaling approximately $ 0.1 million and $ 0.6 million, respectively, which is recorded within the Other line item in our consolidated statements of operations. Investment in SST VI OP On March 10, 2021, SmartStop OP made an investment of $ 5.0 million in SST VI OP, in exchange for common units of limited partnership interest in SST VI OP. On March 11, 2021, SST VI OP, through a wholly-owned subsidiary, used these funds, in part, to acquire its first self storage facility in Phoenix, Arizona for approximately $ 16 million. In connection with SST VI OP’s acquisition of the Phoenix property, we provided a $ 3.5 million mezzanine loan to a wholly-owned subsidiary of SST VI OP with an initial interest rate of 8.5 % and term of six months ; as well as a 180 day extension option which was exercised and increased the interest rate to 9.25 % for the remainder of the term. On April 16, 2021, in connection with SST VI OP’s investment in a real estate joint venture property located in North York, Ontario Canada, we provided a $ 2.1 million term loan with similar terms as the mezzanine loan discussed above. On November 12, 2021, SST VI OP repaid the outstanding balance on the $ 3.5 million mezzanine loan and the $ 2.1 million term loan along with all accrued interest. The loans were terminated in accordance with the mezzanine loan agreement and the term loan agreement without fees or penalties. On December 30, 2021, in connection with SST VI's acquisition of two self storage facilities, SmartStop OP entered into a mezzanine loan agreement with SST VI OP for up to $ 45 million (the “SST VI Mezzanine Loan”). The SST VI Mezzanine Loan required a commitment fee equal to 1.0 % of the amount drawn at closing of the SST VI Mezzanine Loan. The SST VI Mezzanine Loan is secured by a pledge of the equity interest in the indirect, wholly-owned subsidiaries of SST VI that collectively currently own two self storage facilities in Florida. SST VI OP also serves as a non-recourse guarantor. The interest rate on the SST VI Mezzanine Loan is a variable rate equal to LIBOR plus 3% . Payments on the SST VI Mezzanine Loan are interest only until December 30, 2022, which is the initial maturity date of the SST VI Mezzanine Loan. SST VI OP may, in certain circumstances, extend the ultimate maturity date of the SST VI Mezzanine Loan through December 30, 2023 upon written notice to us, in which event the interest rate of the SST VI Mezzanine Loan will increase to LIBOR plus 4% per annum. The SST VI Mezzanine Loan may be prepaid in whole or in part at any time without fees or penalty and, in certain circumstances, equity interests securing the SST VI Mezzanine Loan may be released from the pledge of collateral. As of December 31, 2021, SST VI OP had borrowed $ 6.8 million pursuant to the SST VI Mezzanine Loan and we were potentially required to fund an additional $ 38.2 million. Additionally, SmartStop OP already had a special limited partnership interest (the “SLP”), whereby SmartStop OP would receive a subordinated distribution upon certain returns on equity being met. For the year ended December 31, 2021, we recorded a loss related to our equity interest in SST VI OP of approximately $ 0.6 million, which is recorded within the Other line item in our consolidated statements of operations. Administrative Services Agreement For the years ended December 31, 2021, and 2020, we incurred fees payable to SAM under the Administrative Services Agreement of approximately $ 0.2 million, and $ 1.9 million, respectively, which were recorded in the Managed REIT Platform expenses line item in our consolidated statements of operations. We recorded reimbursements from SAM of approximately $ 0.6 million and $ 0.4 million during the years ended December 31, 2021 and 2020, respectively, related to services provided to SAM as well as reimbursements of rent and overhead for the portion of the Ladera Office occupied by SAM, which were included in Managed REIT Platform revenue in our consolidated statement of operations. As of December 31, 2021, a receivable of approximately $ 60,000 was due from SAM related to the Administrative Services Agreement and included in the other assets line in our consolidated balance sheet. As of December 31, 2020, a receivable of approximately $ 50,000 was due from SAM related to the Administrative Services Agreement and included in the due to affiliates line in our consolidated balance sheet.

Equity Based Compensation

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Equity Based Compensation	Note 11. Equity Based Compensation We issue equity based compensation pursuant to the employee and director long-term incentive plan of SmartStop Self Storage REIT, Inc. (the “Plan”). Pursuant to the Plan, we are able to issue various forms of equity based compensation. Through December 31, 2021, we have issued equity based awards in two forms: (1) restricted stock awards consisting of shares of our common stock and (2) long-term incentive plan units of our Operating Partnership (“LTIP Units”). Through March 2020, we had only issued restricted stock, which shares are subject to a time based vesting period. In April 2020 the Compensation Committee of the Board of Directors approved the 2020 executive compensation program for our executive officers, which included (1) performance based awards, and (2) time based awards. For both such awards the recipient could choose either LTIP Units or restricted stock consisting of shares of our common stock. The fair value of the restricted stock and the LTIP Units was determined based on an estimated value per share, adjusted for an illiquidity discount due to the illiquid nature of the underlying equity. The fair value of the LTIP Units was further adjusted by applying an additional discount as the LTIP Units are not initially economically equivalent to our restricted stock. For the performance based awards, a fair value was determined for each performance ranking scenario, with stock compensation expense recorded using the fair value of the scenario determined to be probable of achievement. Time Based Awards We have granted various time based awards, which generally vest ratably over either one , three , or four years commencing in the year of grant, subject to the recipient’s continued employment or service through the applicable vesting date. All grants of time based restricted stock have limitations on transferability during the vesting period, and the grantee does not have the ability to vote any unvested shares. Transferability during the vesting period depends upon when the grant was made, as follows (i) with respect to grants of time based restricted stock made prior to April 2020, the restriction on transfers applies to the entirety of the grant, regardless of vesting, and (ii) with respect to grants of time based restricted stock made in or subsequent to April 2020, the restriction on transfer applies only to the unvested portion of the restricted stock. With respect to grants of time based LTIPs made to our executive officers in 2020 and 2021, distributions began to accrue effective January 1, 2020 and January 1, 2021 respectively, and are payable as distributions are paid on our Class A Shares without regard to whether the underlying restricted shares have vested. With respect to time based restricted stock, distributions accrue on non-vested shares granted and are paid when the underlying restricted shares vest. Holders of time based LTIP Units receive allocations of profits and losses with respect to the LTIP Units as of the effective date, distributions from the effective date in an amount equivalent to the distributions declared and paid on our Class A Shares, and the same voting rights as holders of common units, voting as a class with each LTIP Unit holder having one vote per LTIP Unit held. Prior to vesting, time based LTIP Units generally may not be transferred, other than by laws of descent and distribution. The following table summarizes the activity related to our time based awards: Restricted Stock LTIPs Time Based Award Grants Shares Weighted-Average Units Weighted-Average Unvested at December 31, 2019 265,806 $ 9.53 — $ — Granted 72,383 9.78 214,521 9.09 Vested ( 82,351 ) 9.55 ( 53,630 ) 9.09 Forfeited ( 6,567 ) 9.78 — — Unvested at December 31, 2020 249,271 $ 9.58 160,891 $ 9.09 Granted 78,192 9.85 222,581 9.30 Vested ( 105,328 ) 9.64 ( 109,276 ) 9.20 Forfeited ( 2,189 ) 9.78 — — Unvested at December 31, 2021 219,946 $ 9.64 274,196 $ 9.22 Performance Based Awards With respect to performance based awards, the number of shares of restricted stock granted as of the grant date equaled 100 % of the targeted award, whereas the number of LTIP Units granted as of the grant date equaled 200 % of the targeted award. The targeted award for each executive was determined and approved by the Compensation Committee of our Board of Directors. The actual number of shares of restricted stock or LTIP Units, as applicable, to be issued upon vesting may range from 0 % to 200 % of the targeted award, such determination being based upon the results of the performance measure. Performance based awards vest based upon our performance as ranked amongst a peer group of publicly traded self storage REITs in terms of the average same-store revenue growth, analyzed over a three year period. This comparison will be conducted using a performance measure of average annual same-store revenue growth, analyzed over a three-year period. Earned awards for the 2020 and 2021 grants will vest, as applicable, no later than March 31, 2023 and March 31, 2024 , respectively. Recipients of performance based restricted stock accrue distributions during the performance period, and such distributions will only be payable on the date that any such shares of restricted stock vest, based upon the performance level attained. Recipients of performance based LTIP Units are issued LTIP Units at 200 % of the targeted award and are entitled to receive distributions and allocations of profits and losses with respect to the performance based LTIP Units as of the effective date of each award in an amount equal to 10% of the distributions and allocations available to such LTIP Units, until the Distribution Participation Date (as defined in the Operating Partnership Agreement). The remaining 90% of distributions will accrue and will be payable on the Distribution Participation Date based upon the performance level attained and number of performance based LTIP Units that vest. Following the Distribution Participation Date, recipients will be entitled to receive the full amount of distributions and allocations of profits and losses with respect to the vested performance-based LTIP Units, such amount being equivalent to distributions declared and paid on our Class A Shares . The following table summarizes our activity related to our performance based awards: Restricted Stock LTIPs Performance Based Award Grants Shares Weighted-Average Units Weighted-Average Unvested at December 31, 2019 — $ — — $ — Granted 5,752 9.78 130,638 9.09 Vested — — — — Forfeited — — — — Unvested at December 31, 2020 5,752 $ 9.78 130,638 $ 9.09 Granted — — 148,387 9.30 Vested — — — — Forfeited — — ( 11,918 ) 9.09 Unvested at December 31, 2021 5,752 $ 9.78 267,107 $ 9.21 Holders of performance based restricted stock do not have any rights as a stockholder with respect to the unvested portion of such restricted stock awards. Prior to vesting, shares of performance based restricted stock generally may not be transferred, other than by laws of descent and distribution. Holders of performance based LTIP Units have the same voting rights as holders of common units, voting as a class with each LTIP Unit holder having one vote per LTIP Unit held. Prior to vesting, performance based LTIP Units generally may not be transferred, other than by laws of descent and distribution. LTIP Units are designed to qualify as “profits interests” in the Operating Partnership for federal income tax purposes. The profits interests’ characteristics of the LTIP Units mean that initially they will not be treated as economically equivalent in value to a common unit and the issuance of LTIP Units will not be a taxable event to the Operating Partnership or the recipient. If and when certain events occur pursuant to applicable tax regulations and in accordance with the Partnership Agreement, LTIP Units may become economically equivalent to common units of limited partnership interest of our Operating Partnership on a one-for-one basis. As of December 31, 2021, 7,366,044 shares of stock were available for issuance under the Plan. We recorded approximately $ 2.8 million, $ 1.6 million, and $ 0.4 million of equity based compensation expense in general and administrative expense during the years ended December 31, 2021, 2020, and 2019, respectively. We recorded approximately $ 80,000 , $ 40,000 , and no ne of equity based compensation expense in property operating expenses, within our consolidated statements of operations for the years ended December 31, 2021, 2020, and 2019, respectively. As of December 31, 2021, and 2020, there was approximately $ 4.5 million and $ 4.0 million of total unrecognized compensation expense related to non-vested equity awards, respectively. As of December 31, 2021 and 2020, such cost was expected to be recognized over a weighted-average period of approximately 2.1 years and 2.5 years, respectively. On February 26, 2021, we announced the retirement of Michael S. McClure, then our Chief Executive Officer, effective as of April 15, 2021 (the “Transition Date”). In connection with Mr. McClure’s retirement, and in order to provide an orderly transition, we entered into an Executive Transition Services Agreement with Mr. McClure (the “Agreement”) on February 26, 2021, pursuant to which Mr. McClure will provide consulting services to the Company for a twelve-month period (the “Transition Period”) commencing on the Transition Date. Pursuant to the Agreement, during the Transition Period and subject to the early termination provisions contained in the Agreement, we will pay Mr. McClure a monthly fee as well as provide reimbursement for costs of continuing group health insurance coverage. Mr. McClure’s existing time-based equity awards will continue to vest during the Transition Period and, upon successful completion of the Transition Period, any remaining outstanding unvested time-based equity awards will immediately vest in full. Mr. McClure’s existing performance-based equity awards will remain outstanding and vest on a pro rata basis at the rate of two-thirds of the amount that would have otherwise vested based on the terms of the awards and actual performance of the Company during the performance period. In April 2021, the compensation committee of our board of directors approved the 2021 executive compensation terms for our executives, which included (1) performance-based equity grants in the form of either, at the election of the executive, restricted stock awards, or LTIP Units, and (2) time-based equity grants in the form of either, at the election of the executive, restricted stock awards or LTIP Units. In April 2021, an aggregate of 148,387 LTIP Units were issued to our executive officers in connection with performance-based equity grants. Similarly, in April 2021 an aggregate of 222,581 LTIP Units were issued to our executive officers in connection with time-based equity grants. These are non-vested grants which shall vest ratably over four years , with the first tranche vesting on December 31, 2021, subject to the recipient’s continued employment through the applicable vesting date.

Commitments and Contingencies	Note 12. Commitments and Contingencies Distribution Reinvestment Plan We have adopted an amended and restated distribution reinvestment plan that allows both our Class A and Class T stockholders to have distributions otherwise distributable to them invested in additional shares of our Class A and Class T Shares, respectively. The purchase price per share pursuant to our distribution reinvestment plan is equivalent to the estimated value per share approved by our board of directors and in effect on the date of purchase of shares under the plan. In conjunction with the board of directors’ declaration of a new estimated value per share of our common stock on October 19, 2021, beginning in October 2021, shares sold pursuant to our distribution reinvestment plan were and will continue to be sold at our new estimated value per share of $ 15.08 per Class A Share and Class T Share . On November 30, 2016, we filed with the SEC a Registration Statement on Form S-3, which registered up to an additional $ 100.9 million in shares under our distribution reinvestment plan (our “DRP Offering”). We may amend or terminate the amended and restated distribution reinvestment plan for any reason at any time upon 10 days ’ prior written notice to stockholders. No sales commissions, dealer manager fee, or stockholder servicing fee will be paid on shares sold through the amended and restated distribution reinvestment plan. Through the termination of our Offering on January 9, 2017, we had sold approximately 1.1 million Class A shares and 0.1 million Class T Shares through our original distribution reinvestment plan. As of December 31, 2021, we had sold approximately 6.9 million Class A Shares and approximately 1.0 million Class T Shares through our DRP Offering. As described below, on March 7, 2022, our board of directors approved the suspension of our DRP, effective on April 15, 2022. Share Redemption Program As described in Note 2 – Summary of Significant Accounting Policies, we have an SRP, which is suspended. Pursuant to the SRP, we may redeem the shares of stock presented for redemption for cash to the extent that such requests comply with the below terms of our SRP and we have sufficient funds available to fund such redemption. Our board of directors may amend, suspend or terminate the SRP with 30 days’ notice to our stockholders. We may provide this notice by including such information in a Current Report on Form 8-K or in our annual or quarterly reports, all publicly filed with the SEC, or by a separate mailing to our stockholders. On August 20, 2020, our board of directors determined that it would be in the best interests of the Company to amend the terms of the SRP to revise the redemption price per share for all redemptions under the SRP to be equal to the most recently published estimated net asset value per share of the applicable share class (the “SRP Amendment”). Prior to the SRP Amendment, the redemption amount was the lesser of the amount the stockholders paid for their shares or the price per share in the current offering. On October 19, 2021, we declared a new estimated net asset value per share and the redemption price under our SRP immediately changed to $ 15.08 (our current estimated net asset value per share) . There are several limitations in addition to those noted above on our ability to redeem shares under the SRP including, but not limited to: • During any calendar year, we will not redeem in excess of 5 % of the weighted-average number of shares outstanding during the prior calendar year. • The cash available for redemption is limited to the proceeds from the sale of shares pursuant to our distribution reinvestment plan, less any prior redemptions. • We have no obligation to redeem shares if the redemption would violate the restrictions on distributions under Maryland law, which prohibits distributions that would cause a corporation to fail to meet statutory tests of solvency. For the year ended December 31, 2021, we received redemption requests totaling approximately $ 5.6 million (approximately 0.4 million shares), approximately $ 3.9 million of which were fulfilled during the year ended December 31, 2021, with the remaining approximately $ 1.7 million included in accounts payable and accrued liabilities as of December 31, 2021 and fulfilled in January 2022. For the year ended December 31, 2020, we received redemption requests totaling approximately $ 2.0 million (approximately 0.2 million shares), approximately $ 1.3 million of which were fulfilled during the year ended December 31, 2020, with the remaining approximately $ 0.7 million included in accounts payable and accrued liabilities as of December 31, 2020 and fulfilled in January 2021. For the year ended December 31, 2019, we received redemption requests totaling approximately $ 4.9 million (approximately 0.5 million shares), approximately $ 4.5 million of which were fulfilled during year ended December 31, 2019, with the remaining approximately $ 0.4 million included in accounts payable and accrued liabilities as of December 31, 2019 and fulfilled in January 2020. As described below, on March 7, 2022, our board of directors approved the complete suspension of our SRP, effective immediately. Suspension of DRP and SRP In connection with a review of liquidity alternatives by our Board, on March 7, 2022, the Board approved the full suspension of our DRP and SRP. Under our DRP, the Board may amend, modify, suspend or terminate our plan for any reason upon 10 days’ written notice to the participants. Consistent with the terms of our DRP, distributions declared by the Board for the month of February 2022, which were paid on or about March 15, 2022, were not affected by this suspension. However, beginning with the distributions declared by the Board for the month of March 2022, which will be paid in April 2022, and continuing until such time as the Board may approve the resumption of the DRP, if ever, all distributions declared by the Board will be paid to our stockholders in cash. Prior to the suspension of our share redemption program, consistent with its terms, all redemption requests received, and not withdrawn, on or prior to the last day of the applicable quarter were processed on the last business day of the month following the end of the quarter in which the redemption requests were received. Accordingly, redemption requests received during the fourth quarter of 2021 were processed on January 31, 2022, and redemption requests received during the first quarter of 2022 ordinarily would have needed to be received on or prior to March 31, 2022 and would have been processed on April 30, 2022. However, the effective date of the aforementioned suspension of our share redemption program occurred prior to March 31, 2022. Accordingly, any redemption requests received during the first quarter of 2022, or any future quarter, will not be processed until such time as the Board may approve the resumption of our share redemption program, if ever. Operating Partnership Redemption Rights Generally, the limited partners of our Operating Partnership, excluding any limited partners with respect to their A-2 Units, have the right to cause our Operating Partnership to redeem their limited partnership units for cash equal to the value of an equivalent number of our shares, or, at our option, we may purchase their limited partnership units by issuing one share of our common stock for each limited partnership unit redeemed. These rights may not be exercised under certain circumstances that could cause us to lose our REIT election. Furthermore, limited partners may exercise their redemption rights only after their limited partnership units have been outstanding for one year . Additionally, the Class A-1 Units issued in connection with the Self Administration Transaction are subject to the general restrictions on transfer contained in the Operating Partnership Agreement. The Class A-1 Units are otherwise entitled to all rights and duties of the Class A limited partnership units in the Operating Partnership, including cash distributions and the allocation of any profits or losses in the Operating Partnership. Other Contingencies We have a severance plan which covers certain officers; this plan provides for severance payments upon certain events, including after a change of control. From time to time, we are party to legal, regulatory and other proceedings that arise in the ordinary course of our business. In accordance with applicable accounting guidance, management accrues an estimated liability when those matters present loss contingencies that are both probable and reasonably estimable. In such cases, there may be an exposure to loss in excess of any amounts accrued. We are not aware of any such proceedings of which the outcome is reasonably likely to have a material adverse effect on our results of operations or financial condition.

Subsequent Events [Abstract]
Subsequent Events	Note 14. Subsequent Events Issuance of Equity Awards In February 2022, the compensation committee of our board of directors approved the 2022 executive compensation terms for our executives, which included (1) performance-based equity grants in the form of either, at the election of the executive, restricted stock awards or LTIP Units, and (2) time-based equity grants in the form of either, at the election of the executive, restricted stock awards or LTIP Units. In February 2022 an aggregate of approximately 113,400 LTIP Units were issued to our executive officers in connection with performance-based equity grants. With respect to performance-based equity grants, the number of LTIP Units granted as of the grant date was equal 200 % of the targeted award. These are non-vested grants which shall vest based on ranges from a threshold of 0 % to a maximum of 200 % of the targeted equity award set for each executive by the compensation committee, with such percentage being determined based upon our ranking as compared to a peer group of publicly traded self storage REITs in terms of the average same-store revenue growth, analyzed over a three-year period. Similarly, in February 2022 an aggregate of approximately 170,100 LTIP Units were issued to our executive officers in connection with time-based equity grants. These are non-vested grants which shall vest ratably over four years , with the first tranche vesting on December 31, 2022, subject to the recipient’s continued employment through the applicable vesting date. Subsequent Acquisitions and Draws on Key Bank Credit Facility On February 8, 2022, we purchased the Algonquin Property for approximately $ 19 million, plus closing costs . Upon acquisition, the property was approximately 72.4 % o ccupied. The acquisition was funded with proceeds from a draw on the KeyBank Credit Facility Revolver of $ 19 million. Potential SSGT II Merger On February 24, 2022, the Company, SSGT II, and SSGT II Merger Sub, entered into the SSGT II Merger Agreement. The SSGT II Merger Agreement provides that we will acquire SSGT II by way of a merger of SSGT II with and into SSGT II Merger Sub, with SSGT II Merger Sub being the surviving entity. At the effective time of the SSGT II Merger (the “Merger Effective Time”), SSGT II shall cease to exist as a separate entity in accordance with the applicable provisions of the Maryland General Corporation Law. The special committee our board of directors (the “SmartStop Special Committee”), our board of directors, and the board of directors of SSGT II (the “SSGT II Board”) have unanimously approved the SSGT II Merger, the SSGT II Merger Agreement, and the transactions contemplated by the SSGT II Merger Agreement. The SmartStop Special Committee is comprised entirely of independent directors of the Company. Pursuant to the terms and subject to the conditions set forth in the SSGT II Merger Agreement, at the SSGT II Merger Effective Time, each share of SSGT II’s common stock, $ 0.001 par value per share (“SSGT II Common Stock”), issued and outstanding immediately prior to the SSGT II Merger Effective Time (other than shares owned by us, any subsidiary of ours, or any subsidiary of SSGT II) will be converted into the right to receive 0.9118 shares of our Class A Shares , subject to the treatment of fractional shares in accordance with the SSGT II Merger Agreement (the “SSGT II Merger Consideration”). Assuming all of the conditions of the SSGT II Merger are satisfied and the SSGT II Merger is consummated in accordance with the terms in the SSGT II Merger Agreement, we will acquire all of the real estate owned by SSGT II, which as of February 24, 2022 consisted of (i) 10 wholly-owned self storage facilities located in seven states comprising approximately 7,740 self storage units and approximately 853,900 net rentable square feet, and (ii) SSGT II’s 50 % equity interest in three unconsolidated real estate ventures located in the Greater Toronto Area of Ontario, Canada. The unconsolidated real estate ventures consist of one operating self storage property and two parcels of land being developed into self storage facilities, with subsidiaries of SmartCentres owning the other 50 % of such entities. The SSGT II Merger Agreement contains customary representations, warranties, and covenants, including covenants relating to the conduct of our business and the business of SSGT II during the period between the execution of the SSGT II Merger Agreement and the earlier of the completion of the SSGT II Merger or the termination of the SSGT II Merger Agreement in accordance with its terms. The closing of the SSGT II Merger (the “Closing”) is subject to and conditioned on the approval of the SSGT II Merger by the affirmative vote of the holders of not less than a majority of all outstanding shares of SSGT II Common Stock (the “Stockholder Approval”). Pursuant to the terms of the SSGT II Merger Agreement, the Closing is also subject to other customary conditions, including the delivery of certain documents and legal opinions, the accuracy of the representations and warranties of the parties (subject to the materiality standards contained in the SSGT II Merger Agreement), the effectiveness of the registration statement on Form S-4 to be filed by us to register the shares to be issued as SSGT II Merger Consideration, and the absence of a “SmartStop Material Adverse Effect” or “SSGT II Material Adverse Effect” (as each term is defined in the Merger Agreement). Our obligation to consummate the SSGT II Merger is not subject to a financing condition. The Closing is not subject to the approval of our stockholders. During the period beginning on the date of the SSGT II Merger Agreement and continuing until 11:59 p.m. (California local time) on March 26, 2022 (the “Go Shop Period End Time”), SSGT II (through the SSGT II Board and its representatives) may initiate, solicit, provide information and enter into discussions concerning proposals relating to alternative Acquisition Proposals (as defined in the Merger Agreement) (the “Go Shop”). The closing of the SSGT II Merger is subject to and conditioned on the approval of the SSGT II Merger by the affirmative vote of the holders of not less than a majority of all outstanding shares of SSGT II Common Stock. The closing of the SSGT II Merger is neither subject to a financing condition nor to the approval of our stockholders. In connection with the termination of the SSGT II Merger Agreement and SSGT II’s entry into an alternative transaction with respect to a Superior Proposal (as defined in the SSGT II Merger Agreement), as well as under other specified circumstances, SSGT II will be required to pay to us a termination payment of $ 2,600,000 in the event of termination arising out of the Go Shop, or $ 5,200,000 in the event of termination under certain other circumstances. In addition, the SSGT II Merger Agreement provides for customary expense reimbursement (not to exceed $ 1,000,000 ) under specified circumstances set forth in the SSGT II Merger Agreement. Suspension of DRP and SRP In connection with a review of liquidity alternatives by our Board, on March 7, 2022, the Board approved the full suspension of our DRP and SRP. Under our DRP, the Board may amend, modify, suspend or terminate our plan for any reason upon 10 days’ written notice to the participants.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) as contained within the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and the rules and regulations of the SEC.
Unaudited Information	Unaudited Information The square footage, unit count, and occupancy percentage data and disclosures included in these notes to the consolidated financial statements are unaudited.
Principles of Consolidation	Principles of Consolidation Our financial statements, and the financial statements of our Operating Partnership, including its wholly-owned subsidiaries, are consolidated in the accompanying consolidated financial statements. The portion of these entities not wholly-owned by us is presented as noncontrolling interests. All intercompany accounts and transactions have been eliminated in consolidation. Strategic Storage Operating Partnership VI, L.P. (“SST VI OP”), the operating partnership of SST VI, and its wholly-owned subsidiaries, were consolidated by us until May 1, 2021. From March 10, 2021 (the date of our initial investment in SST VI OP) until May 1, 2021, the portion not wholly-owned by us was presented as noncontrolling interests, and all intercompany accounts and transactions were eliminated in consolidation during that period.
Consolidation Considerations	Consolidation Considerations Current accounting guidance provides a framework for identifying a variable interest entity (“VIE”) and determining when a company should include the assets, liabilities, noncontrolling interests, and results of activities of a VIE in its consolidated financial statements. In general, a VIE is an entity or other legal structure used to conduct activities or hold assets that either (1) has an insufficient amount of equity to carry out its principal activities without additional subordinated financial support, (2) has a group of equity owners that are unable to make significant decisions about its activities, or (3) has a group of equity owners that do not have the obligation to absorb losses or the right to receive returns generated by its operations. Generally, a VIE should be consolidated if a party with an ownership, contractual, or other financial interest in the VIE (a variable interest holder) has the power to direct the VIE’s most significant activities and the obligation to absorb losses or right to receive benefits of the VIE that could be significant to the VIE. A variable interest holder that consolidates the VIE is called the primary beneficiary. Upon consolidation, the primary beneficiary generally must initially record all of the VIE’s assets, liabilities, and noncontrolling interest at fair value and subsequently account for the VIE as if it were consolidated based on majority voting interest. Our Operating Partnership is deemed to be a VIE and is consolidated by the Company as we are currently the primary beneficiary. Our sole significant asset is our investment in our Operating Partnership; as a result, substantially all of our assets and liabilities represent those assets and liabilities of our Operating Partnership and its wholly-owned subsidiaries. Additionally, from March 10, 2021 until May 1, 2021, we were deemed to be the primary beneficiary of SST VI OP, and their operations were therefore consolidated by us. Subsequent to May 1, 2021, we are no longer the primary beneficiary, and their operations are no longer consolidated by us. As of December 31, 2021, we were not a party to any other contracts/interests that would be deemed to be variable interests in VIEs other than our joint ventures with SmartCentres acquired in the SST IV Merger, which are all accounted for under the equity method of accounting (see Note 4 – Investments in Unconsolidated Real Estate Ventures for additional information), and our Tenant Protection Programs joint venture with SSGT II and SST VI, which are consolidated. As of December 31, 2020, we were also a party to and consolidated our Tenant Protection Programs joint venture with SST IV, which became a wholly-owned entity as a result of the SST IV Merger.
Equity Investments	Equity Investments Under the equity method, our investments will be stated at cost and adjusted for our share of net earnings or losses and reduced by distributions and impairments, as applicable. Equity in earnings will generally be recognized based on our ownership interest in the earnings of each of the unconsolidated investments.
Investments in and Advances to Managed REITs	Investments in and Advances to Managed REITs As of December 31, 2021, and 2020, we owned equity and debt investments with a carrying value of approximately $ 11.0 million, and $ 15.1 million, respectively, in the Managed REITs; such amounts are included in Investments in and advances to Managed REITs within our consolidated balance sheets. We account for our equity investments using the equity method of accounting as we have the ability to exercise significant influence, but not control, over the Managed REITs’ operating and financial policies through our advisory and property management agreements with the respective Managed REITs. The equity method of accounting requires the investment to be initially recorded at cost and subsequently adjusted for our share of equity in the respective Managed REIT’s earnings and reduced by distributions. We record the interest on the debt investments on the accrual basis and such income is included in other in our consolidated statements of operations. Also included in Investments in and advances to Managed REITs as of December 31, 2021 are receivables from the Managed REITs of approximately $ 1.4 million. As of December 31, 2020, receivables from the Managed REITs approximated $ 0.5 million. For additional discussion, see Note 10 – Related Party Transactions.
Noncontrolling Interests in Consolidated Entities	Noncontrolling Interests in Consolidated Entities We account for the noncontrolling interests in our Operating Partnership and the noncontrolling interests in our Tenant Protection Programs joint ventures with SSGT II and SST VI in accordance with the related accounting guidance. Due to our control through our general partnership interest in our Operating Partnership and the limited rights of the limited partners, our Operating Partnership, including its wholly-owned subsidiaries, are consolidated with the Company and the limited partner interests are reflected as noncontrolling interests in the accompanying consolidated balance sheets. We also consolidate our interests in the SSGT II and SST VI Tenant Protection Programs and present the minority interests as noncontrolling interests in the accompanying consolidated balance sheets. The noncontrolling interests shall be attributed their share of income and losses, even if that attribution results in a deficit noncontrolling interest balance .
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The current economic environment has increased the degree of uncertainty inherent in these estimates and assumptions. Management will adjust such estimates when facts and circumstances dictate. Actual results could materially differ from those estimates. The most significant estimates made include the allocation of property purchase price to tangible and intangible assets acquired and liabilities assumed at relative fair value, the ongoing fair value determination of contingent liabilities, the determination if certain entities should be consolidated, the evaluation of potential impairment of indefinite and long-lived assets and goodwill, and the estimated useful lives of real estate assets and intangibles.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all short-term, highly liquid investments that are readily convertible to cash with a maturity of three months or less at the time of purchase to be cash equivalents. We may maintain cash and cash equivalents in financial institutions in excess of insured limits, but believe this risk will be mitigated by only investing in or through major financial institutions.
Restricted Cash	Restricted Cash Restricted cash consists primarily of impound reserve accounts for property taxes, insurance and capital improvements in connection with the requirements of certain of our loan agreements.
Real Estate Purchase Price Allocation	Real Estate Purchase Price Allocation We account for acquisitions in accordance with GAAP which requires that we allocate the purchase price of a property to the tangible and intangible assets acquired and the liabilities assumed based on their relative fair values as of the date of acquisition. This guidance requires us to make significant estimates and assumptions, including fair value estimates, which requires the use of significant unobservable inputs as of the acquisition date. We engage third-party valuation specialists to assist in the determination of significant estimates and market-based assumptions used in the valuation models. The value of the tangible assets, consisting of land and buildings, is determined as if vacant. Substantially all of the leases in place at acquired properties are at market rates, as the majority of the leases are month-to-month contracts. We also consider whether in-place, market leases represent an intangible asset. We recorded approximately $ 21.5 million, none , and $ 13.6 million in intangible assets to recognize the value of in-place leases related to our acquisitions during the years ended December 31, 2021, 2020 and 2019, respectively. We do not expect, nor to date have we recorded, intangible assets for the value of customer relationships because we expect we will not have concentrations of significant customers and the average customer turnover will be fairly frequent. Allocation of purchase price to acquisitions of portfolios of facilities are allocated to the individual facilities based upon an income approach or a cash flow analysis using appropriate risk adjusted capitalization rates which take into account the relative size, age, and location of the individual facility along with current and projected occupancy and rental rate levels or appraised values, if available. Other factors considered as part of the purchase price allocation include historical operating data related to the properties, land sales comparisons, growth rates and discount rates. Acquisitions that do not meet the definition of a business, as defined under current GAAP, are accounted for as asset acquisitions. During the years ended December 31, 2021 and 2020, our property acquisitions did not meet the definition of a business because substantially all of the fair value was concentrated in a single identifiable asset or group of similar identifiable assets (i.e. land, buildings, and related intangible assets) or because the acquisitions did not include a substantive process in the form of an acquired workforce or an acquired contract that cannot be replaced without significant cost, effort or delay. As a result, once an acquisition is deemed probable, transaction costs are capitalized rather than expensed. During the years ended December 31, 2021, 2020, and 2019 we expensed approximately $ 0.9 million, $ 1.4 million, and $ 0.2 million, respectively, of acquisition-related transaction costs that did not meet our capitalization policy during the respective periods.
Purchase Price Allocation for the Acquisition of a Business	Purchase Price Allocation for the Acquisition of a Business Should the initial accounting for an acquisition that meets the definition of a business be incomplete by the end of a reporting period that falls within the measurement period, we report provisional amounts in our financial statements. During the measurement period, we may adjust the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date and we record those adjustments to our financial statements. We apply any measurement period adjustments in the period in which the provisional amounts are finalized. As discussed in Note 5 – Self Administration Transaction, the Self Administration Transaction was an acquisition of a business.
Evaluation of Possible Impairment of Real Property Assets	Evaluation of Possible Impairment of Real Property Assets Management monitors events and changes in circumstances that could indicate that the carrying amounts of our real property assets may not be recoverable. When indicators of potential impairment are present that indicate that the carrying amounts of the assets may not be recoverable, we will assess the recoverability of the assets by determining whether the carrying value of the real property assets will be recovered through the undiscounted future operating cash flows expected from the use of the asset and its eventual disposition. In the event that such expected undiscounted future cash flows do not exceed the carrying value, we will adjust the value of the real property assets to the fair value and recognize an impairment loss. For the years ended December 31, 2021, 2020, and 2019, no impairment losses were recognized.
Goodwill Valuation	Goodwill Valuation We initially recorded goodwill as a result of the Self Administration Transaction. Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible assets and other intangible assets acquired. Goodwill is allocated to various reporting units, as applicable, and is not amortized. We perform an annual impairment test for goodwill, and between annual tests, we evaluate the recoverability of goodwill whenever events or changes in circumstances indicate that the carrying amount of goodwill may not be fully recoverable. In our impairment test of goodwill, we perform a quantitative analysis to compare the fair value of each reporting unit to its respective carrying amount. If the carrying amount of goodwill exceeds its fair value, an impairment charge will be recognized. See Note 5 – Self Administration Transaction for additional information.
Trademarks	Trademarks In connection with the Self Administration Transaction, we recorded the fair value associated with the two primary trademarks acquired therein. Trademarks are based on the value of our brands. Trademarks are valued using the relief from royalty method, which presumes that without ownership of such trademarks, we would have to make a stream of payments to a brand or franchise owner in return for the right to use their name. By virtue of this asset, we avoid any such payments and record the related intangible fair value of our ownership of the brand name. As of December 31, 2021 and December 31, 2020, $ 15.7 million was recorded related to the SmartStop® Self Storage trademark, which is an indefinite lived trademark. As of December 31, 2021 and December 31, 2020, approximately $ 0.4 million and $ 0.5 million, respectively, was recorded to the “Strategic Storage ®” trademark, which is a definite lived trademark. The total estimated future amortization expense of the “Strategic Storage®” trademark asset for the years ending December 31, 2022, 2023, 2024, and thereafter is approximately $ 140,000 , $ 140,000 , $ 70,000 , and none thereafter, respectively. We qualitatively evaluate whether any triggering events or changes in circumstances have occurred subsequent to our annual impairment test that would indicate an impairment condition may exist. If any change in circumstance or triggering event occurs, and results in a significant impact to our revenue and profitability projections, or any significant assumption in our valuation methods is adversely impacted, the impact could result in a material impairment charge in the future. See Note 5 – Self Administration Transaction for additional information.
Revenue Recognition	Revenue Recognition Self Storage Operations Management believes that all of our leases are operating leases. Rental income is recognized in accordance with the terms of the leases, which generally are month-to-month. Revenues from any long-term operating leases are recognized on a straight-line basis over the term of the lease. The excess of rents received over amounts contractually due pursuant to the underlying leases is included in accounts payable and accrued liabilities in our consolidated balance sheets, and contractually due but unpaid rent is included in other assets. Managed REIT Platform We earn property management and asset management revenue, pursuant to the respective property management and advisory agreement contracts, in connection with providing services to the Managed REITs. We have determined under ASC 606 – Revenue from Contracts with Customers (“ASC 606”), that the performance obligation for the property management services and asset management services are satisfied as the services are rendered. While we are compensated for our services on a monthly basis, these services represent a series of distinct daily services in accordance with ASC 606. Such revenue is recorded in the Managed REIT Platform revenue line within our consolidated statements of operations. The Managed REITs’ advisory agreements also provide for reimbursement to us of our direct and indirect costs of providing administrative and management services to the Managed REITs. These reimbursements include costs incurred in relation to organization and offering services provided to the Managed REITs and the reimbursement of salaries, bonuses, and other expenses related to benefits paid to our employees while performing services for the Managed REITs. T he Managed REITs’ property management agreements also provide r eimbursement to us for the property manager’s costs of managing the properties. Reimbursable costs include wages and salaries and other expenses that arise in operating, managing and maintaining the Managed REITs’ properties. Under ASC 606, direct reimbursement of such costs does not represent a separate performance obligation from our obligation to perform property management and asset management services. The reimbursement income is considered variable consideration, and is recognized as the costs are incurred, subject to limitations on the Managed REIT Platform’s ability to incur offering costs or limitations imposed by the advisory agreements. We have elected to separately record such revenue in the Reimbursable costs from Managed REITs line within our consolidated statements of operations. Additionally, we earn revenue in connection with our Tenant Protection Programs joint ventures with our Managed REITs. We also earn development and construction management revenue from services we provide in connection with the project design, coordination and oversite of development and certain capital improvement projects undertaken by the Managed REITs. We recognize such revenue in the Managed REIT Platform revenue line within our consolidated statements of operations as the services are performed or delivered. See Note 10 – Related Party Transactions, for additional information regarding revenue generated from our Managed REIT Platform.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts Tenant accounts receivable is reported net of an allowance for doubtful accounts. Management records this general reserve estimate based upon a review of the current status of accounts receivable. It is reasonably possible that management’s estimate of the allowance will change in the future . As of December 31, 2021 and 2020, approximately $ 0.5 million and $ 0.3 million were recorded to allowance for doubtful accounts, respectively.
Advertising Costs	Advertising Costs Advertising costs are expensed in the period in which the cost is incurred and are included in property operating expenses and general and administrative lines within our consolidated statements of operations, depending on the nature of the expense. The Company incurred advertising costs of approximately $ 3.7 million, $ 2.9 million, and $ 2.9 million for the years ended December 31, 2021, 2020, and 2019, respectively, within property operating expenses, and approximately $ 0.8 million, $ 0.6 million, and $ 0.7 million for the years ended December 31, 2021, 2020, and 2019, respectively, within general and administrative.
Real Estate Facilities	Real Estate Facilities We capitalize costs incurred to develop, construct, renovate and improve properties, including interest and property taxes incurred during the construction period. The construction period begins when expenditures for the real estate assets have been made and activities that are necessary to prepare the asset for its intended use are in progress. The construction period ends when the asset is substantially complete and ready for its intended use.
Depreciation of Real Property Assets	Depreciation of Real Property Assets Our management is required to make subjective assessments as to the useful lives of our depreciable assets. We consider the period of future benefit of the asset to determine the appropriate useful lives. Depreciation of our real property assets is charged to expense on a straight-line basis over the estimated useful lives Description Standard Land Not Depreciated Buildings 30 - 40 years Site Improvements 7 - 10 years
Depreciation of Personal Property Assets	Depreciation of Personal Property Assets Personal property assets consist primarily of furniture, fixtures and equipment and are depreciated on a straight-line basis over the estimated useful lives, generally ranging from 3 to 5 years , and are included in other assets on our consolidated balance sheets.
Intangible Assets	Intangible Assets We have allocated a portion of our real estate purchase price to in-place lease intangibles. We amortize in-place lease intangibles on a straight-line basis over the estimated future benefit period, which is generally 18 months . As of December 31, 2021, the gross amount allocated to in-place lease intangibles was approximately $ 68.6 million and accumulated amortization of in-place lease intangibles totaled approximately $ 56.8 million. As of December 31, 2020, the gross amounts allocated to in-place lease intangibles were approximately $ 47.3 million and accumulated amortization of in-place lease intangibles totaled approximately $ 45.7 million. The total estimated future amortization expense of intangible assets related to our self storage properties for the years ending December 31, 2022, 2023, 2024, 2025, and thereafter is approximately $ 10.5 million, $ 0.2 million, $ 0.1 million, $ 0.1 million, and $ 1.0 million respectively. In connection with the Self Administration Transaction, we allocated a portion of the consideration to the contracts that we acquired related to the Managed REITs and the customer relationships related to the Tenant Protection Programs joint ventures. For these intangibles, we are amortizing such amounts on a straight-line basis over the estimated benefit period of the contracts and customer relationships. As of December 31, 2021, the gross amount of the intangible assets related to the Managed REITs contracts and the customer relationships related to the Tenant Protection Programs joint ventures was approximately $ 6.8 million and the accumulated amortization was approximately $ 4.3 million. As of December 31, 2020, the gross amount of the intangibles related to the Managed REITs contracts and the customer relationships related to the Tenant Protection Programs joint ventures was approximately $ 18.1 million and accumulated amortization of those intangibles totaled approximately $ 7.3 million. The total estimated future amortization expense for such intangible assets for the years ending December 31, 2022, 2023, 2024, 2025 and thereafter is approximately $ 0.7 million, $ 0.7 million, $ 0.7 million, $ 0.3 million and none thereafter, respectively. We evaluate whether any triggering events or changes in circumstances have occurred subsequent to our annual impairment test that would indicate an impairment condition may exist. If any change in circumstance or triggering event occurs, and results in a significant impact to our revenue and profitability projections, or any significant assumption in our valuations methods is adversely impacted, the impact could result in a material impairment charge in the future. See Note 5 – Self Administration Transaction for additional information.
Debt Issuance Costs	Debt Issuance Costs The net carrying value of costs incurred in connection with obtaining non revolving debt are presented on the balance sheet as a deduction from debt; amounts incurred related to obtaining revolving debt are included in the debt issuance costs line on our consolidated balance sheet (see Note 6 – Debt). Debt issuance costs are amortized using the effective interest method. As of December 31, 2021, the gross amount of debt issuance costs related to our revolving credit facility totaled approximately $ 4.1 million and accumulated amortization of debt issuance costs related to our revolving credit facility totaled approximately $ 0.8 million. As of December 31, 2020, the gross amount of debt issuance costs related to our revolving credit facility totaled none , and accumulated amortization of debt issuance costs related to our revolving credit facility totaled none . As of December 31, 2021, the gross amount allocated to debt issuance costs related to non-revolving debt totaled approximately $ 5.8 million and accumulated amortization of debt issuance costs related to non-revolving debt totaled approximately $ 1.9 million. As of December 31, 2020, the gross amount allocated to debt issuance costs related to non-revolving debt totaled approximately $ 12.0 million and accumulated amortization of debt issuance costs related to non-revolving debt totaled approximately $ 7.9 million.
Organizational and Offering Costs	Organizational and Offering Costs We pay our Former Dealer Manager an ongoing stockholder servicing fee that is payable monthly and accrues daily in an amount equal to 1/365th of 1% of the purchase price per share of the Class T Shares sold in the Primary Offering. In accordance with the selling agreements we entered into with respect to the sale of Class T Shares, we will cease paying the stockholder servicing fee with respect to the Class T Shares sold in the Primary Offering at the earlier of (i) the date we list our shares on a national securities exchange, merge or consolidate with or into another entity, or sell or dispose of all or substantially all of our assets; (ii) the date at which the aggregate underwriting compensation from all sources equals 10 % of the gross proceeds from the sale of both Class A Shares and Class T Shares in our Primary Offering, which calculation shall be made by us with the assistance of our Former Dealer Manager commencing after the termination of the Primary Offering; (iii) the fifth anniversary of the last day of the fiscal quarter in which our Primary Offering (i.e., excluding our distribution reinvestment plan offering) terminated (or March 31, 2022); and (iv) the date that such Class T Share is redeemed or is no longer outstanding. Our Former Dealer Manager entered into participating dealer agreements with certain other broker-dealers which authorized them to sell our shares. Upon sale of our shares by such broker-dealers, our Former Dealer Manager re-allowed all of the sales commissions and, subject to certain limitations, the stockholder servicing fees paid in connection with sales made by these broker-dealers. Our Former Dealer Manager was also permitted to re-allow to these broker-dealers a portion of their dealer manager fee as marketing fees, reimbursement of certain costs and expenses of attending training and education meetings sponsored by our Former Dealer Manager, payment of attendance fees required for employees of our Former Dealer Manager or other affiliates to attend retail seminars and public seminars sponsored by these broker-dealers, or to defray other distribution-related expenses. We recorded a liability within due to affiliates for the future estimated stockholder servicing fees at the time of sale of Class T Shares as an offering cost.
Foreign Currency Translation	Foreign Currency Translation For non-U.S. functional currency operations, assets and liabilities are translated to U.S. dollars at current exchange rates. Revenues and expenses are translated at the average rates for the period. All adjustments related to amounts classified as long term net investments are recorded in accumulated other comprehensive income (loss) as a separate component of equity. Transactions denominated in a currency other than the functional currency of the related operation are recorded at rates of exchange in effect at the date of the transaction. Changes in investments not classified as long term are recorded in other income (expense) and represented a loss of approximately $ 3.8 million and a gain of approximately $ 0.6 million for the years ended December 31, 2021 and 2020, respectively.
Redeemable Common Stock	Redeemable Common Stock We adopted a share redemption program (“SRP”) that enables stockholders to sell their shares to us in limited circumstances. We record amounts that are redeemable under the SRP as redeemable common stock in the accompanying consolidated balance sheets since the shares are redeemable at the option of the holder and therefore their redemption is outside our control. The maximum amount redeemable under our SRP is limited to the number of shares we can repurchase with the amount of the net proceeds from the sale of shares under the distribution reinvestment plan. However, accounting guidance states that determinable amounts that can become redeemable should be presented as redeemable when such amount is known. Therefore, the net proceeds from the distribution reinvestment plan are considered to be temporary equity and are presented as redeemable common stock in the accompanying consolidated balance sheets. In addition, current accounting guidance requires, among other things, that financial instruments that represent a mandatory obligation of us to repurchase shares be classified as liabilities and reported at settlement value. When we determine we have a mandatory obligation to repurchase shares under the SRP, we reclassify such obligations from temporary equity to a liability based upon their respective settlement values. On August 26, 2019, our board of directors approved a partial suspension of our SRP, effective as of September 27, 2019, so that common shares were redeemable at the option of the holder only in connection with (i) death or disability of a stockholder, (ii) confinement to a long-term care facility, or (iii) other exigent circumstances . In order to preserve cash in light of the uncertainty relating to COVID-19 and its potential impact on our overall financial results, on March 30, 2020, our board of directors approved the complete suspension of our SRP, effective on April 29, 2020. Due to the complete suspension, we were unable to honor redemption requests made during the quarter ended March 31, 2020 or the quarter ended June 30, 2020. On August 20, 2020, our board of directors determined that it would be in our best interests to partially reinstate the SRP, effective as of September 23, 2020. As of December 31, 2021, our redemption program remained suspended other than for redemptions sought in connection with a stockholder’s death, qualifying disability, confinement to a long-term care facility or other exigent circumstances. On March 7, 2022, the board of directors approved the complete suspension of the Company's SRP. See Note 12 – Commitments and Contingencies of the Notes to the Consolidated Financial Statements contained in this report for additional information. For the year ended December 31, 2021, we received redemption requests totaling approximately $ 5.6 million (approximately 0.4 million shares), approximately $ 3.9 million of which were fulfilled during the year ended December 31, 2021, with the remaining approximately $ 1.7 million included in accounts payable and accrued liabilities as of December 31, 2021 and fulfilled in January 2022. For the year ended December 31, 2020, we received redemption requests totaling approximately $ 2.0 million (approximately 0.2 million shares), approximately $ 1.3 million of which were fulfilled during the year ended December 31, 2020, with the remaining approximately $ 0.7 million included in accounts payable and accrued liabilities as of December 31, 2020 and fulfilled in January 2021. For the year ended December 31, 2019, we received redemption requests totaling approximately $ 4.9 million (approximately 0.5 million shares), approximately $ 4.5 million of which were fulfilled during the year ended December 31, 2019, with the remaining approximately $ 0.4 million included in accounts payable and accrued liabilities as of December 31, 2019 and fulfilled in January 2020.
Accounting for Equity Awards	Accounting for Equity Awards We issue equity based awards in two forms: (1) restricted stock awards consisting of shares of our common stock and (2) long-term incentive plan units of our Operating Partnership (“LTIP Units”), both of which may be issued subject to either time based vesting criteria or performance based vesting criteria restrictions. For time based awards granted which contain a graded vesting schedule, compensation cost is recognized as an expense on a straight-line basis over the requisite service period as if the award was, in substance, a single award. For performance based awards, compensation cost is recognized over the requisite service period if and when we determine the performance condition is probable of being achieved. We record the cost of such equity based awards based on the grant date fair value, and have elected to record forfeitures as they occur.
Employee Benefit Plan	Employee Benefit Plan The Company terminated its relationship with a professional employer organization and began maintaining its own retirement savings plan during the year ended 2021 under Section 401(k) of the Internal Revenue Code under which eligible employees can contribute up to 100 % of their annual salary, subject to a statutory prescribed annual limit. For the year ended December 31, 2021, the Company made matching contributions to such plan of approximately $ 0.2 million, based on a company match of 100 % on the first 4 % of an employee’s compensation.
Fair Value Measurements	Fair Value Measurements Under GAAP, we are required to measure certain financial instruments at fair value on a recurring basis. In addition, we are required to measure other financial instruments and balances at fair value on a non-recurring basis. Fair value is defined by the accounting standard for fair value measurements and disclosures as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. It also establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels. The following summarizes the three levels of inputs and hierarchy of fair value we use when measuring fair value: • Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access; • Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as interest rates and yield curves that are observable at commonly quoted intervals; and • Level 3 inputs are unobservable inputs for the assets or liabilities that are typically based on an entity’s own assumptions as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the fair value measurement will fall within the lowest level that is significant to the fair value measurement in its entirety. The accounting guidance for fair value measurements and disclosures provides a framework for measuring fair value and establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. In determining fair value, we will utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as consider counterparty credit risk in our assessment of fair value. Considerable judgment will be necessary to interpret Level 2 and 3 inputs in determining fair value of our financial and non-financial assets and liabilities. Accordingly, there can be no assurance that the fair values we will present will be indicative of amounts that may ultimately be realized upon sale or other disposition of these assets. Financial and non-financial assets and liabilities measured at fair value on a non-recurring basis in our consolidated financial statements consist of real estate and related liabilities assumed related to our acquisitions along with the assets and liabilities described in Note 3 – Real Estate Facilities and Note 5 – Self Administration Transaction. The fair values of these assets and liabilities were determined as of the acquisition dates using widely accepted valuation techniques, including (i) discounted cash flow analysis, which considers, among other things, leasing assumptions, growth rates, discount rates and terminal capitalization rates, (ii) income capitalization approach, which considers prevailing market capitalization rates, and (iii) comparable sales activity. Additionally, certain such assets and liabilities are required to be fair valued periodically or valued pursuant to ongoing fair value requirements and impairment analyses and have been valued subsequently utilizing the same techniques noted above. In general, we consider multiple valuation techniques when measuring fair values. However, in certain circumstances, a single valuation technique may be appropriate. All of the fair values of the assets and liabilities as of the acquisition dates were derived using Level 3 inputs. The carrying amounts of cash and cash equivalents, restricted cash, other assets, variable-rate debt, accounts payable and accrued liabilities, distributions payable and amounts due to affiliates approximate fair value. The table below summarizes our fixed rate notes payable at December 31, 2021 and 2020. The estimated fair value of financial instruments is subjective in nature and is dependent on a number of important assumptions, including discount rates and relevant comparable market information associated with each financial instrument. The fair value of the fixed rate notes payable was estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. The use of different market assumptions and estimation methodologies may have a material effect on the reported estimated fair value amounts. Accordingly, the estimates presented below are not necessarily indicative of the amounts we would realize in a current market exchange. December 31, 2021 December 31, 2020 Fair Value Carrying Value Fair Value Carrying Value Fixed Rate Secured Debt $ 353,600,000 $ 340,967,113 $ 316,000,000 $ 301,988,969 As of December 31, 2021 and 2020, we had interest rate swaps, interest rate caps, and a net investment hedge (See Notes 6 and 8). The valuations of these instruments were determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of the derivative. The analyses reflect the contractual terms of the derivatives, including the period to maturity, and used observable market-based inputs, including interest rate curves, foreign exchange rates, and implied volatilities. The fair value of the interest rate swaps were determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash payments. Our fair values of our net investment hedges are based primarily on the change in the spot rate at the end of the period as compared with the strike price at inception. To comply with GAAP, we incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of derivative contracts for the effect of non-performance risk, we consider the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. Although we had determined that the majority of the inputs used to value our derivatives were within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilized Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by us and our counterparties. However, through December 31, 2021, we had assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and determined that the credit valuation adjustments were not significant to the overall valuation of our derivatives. As a result, we determined that our derivative valuations in their entirety were classified in Level 2 of the fair value hierarchy.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities We record all derivatives on our balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. We may enter into derivative contracts that are intended to economically hedge certain of our risks, even though hedge accounting does not apply or we elect not to apply hedge accounting. For derivatives designated as net investment hedges, the effective portion of changes in the fair value of the derivatives are reported in accumulated other comprehensive income (loss). The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. Amounts are reclassified out of other comprehensive (loss) income into earnings (loss) when the hedged net investment is either sold or substantially liquidated.
Income Taxes	Income Taxes We made an election to be taxed as a Real Estate Investment Trust (“REIT”), under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”), commencing with our taxable year ended December 31, 2014. To qualify as a REIT, we must continue to meet certain organizational and operational requirements, including a requirement to distribute at least 90 % of the REIT’s ordinary taxable income to stockholders (which is computed without regard to the dividends paid deduction or net capital gains and which does not equal net income as calculated in accordance with GAAP) . For income tax purposes, distributions to common stockholders are characterized as ordinary dividends, capital gain dividends, or as nontaxable distributions. To the extent that we make a distribution in excess of our current or accumulated earnings and profits, the distribution will be a non-taxable return of capital, reducing the tax basis in each U.S. stockholder’s shares, and the amount of each distribution in excess of a U.S. stockholder’s tax basis in its shares will be taxable as gain realized from the sale of its shares. As a REIT, we generally will not be subject to U.S. federal income tax on taxable income that we distribute to our stockholders. If we fail to qualify as a REIT in any taxable year, we will then be subject to U.S. federal income taxes on our taxable income at regular corporate rates and will not be permitted to qualify for treatment as a REIT for U.S. federal income tax purposes for four years following the year during which qualification is lost unless the IRS grants us relief under certain statutory provisions. Such an event could materially adversely affect our net income and net cash available for distribution to stockholders. However, we believe that we are organized and operate in such a manner as to qualify for treatment as a REIT and intend to operate in the foreseeable future in such a manner that we will remain qualified as a REIT for U.S. federal income tax purposes. Even if we continue to qualify for taxation as a REIT, we may be subject to certain state, local, and foreign taxes on our income and property, and federal income and excise taxes on our undistributed income. We filed an election to treat our TRS as a taxable REIT subsidiary effective January 1, 2014. In general, our TRS performs additional services for our customers and provides the advisory and property management services to the Managed REITs and otherwise generally engages in any real estate or non-real estate related business. The TRS is subject to corporate federal and state income tax. Deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities. As of December 31, 2021, the net deferred tax liability of approximately $ 7.7 million was comprised of a deferred tax liability of approximately $ 0.6 million related to our intangible assets acquired in the Self Administration Transaction, and a net deferred tax liability of approximately $ 7.1 million recorded at certain of our Canadian entities’ properties. The $ 7.1 million net deferred tax liability is comprised of a gross deferred tax liability of approximately $ 10.2 million, net of a gross deferred tax asset of approximately $ 3.1 million As of December 31, 2020, the net deferred tax liability of approximately $ 8.4 million was comprised of a deferred tax liability of approximately $ 2.6 million related to our intangible assets acquired in the Self Administration Transaction, and a net deferred tax liability of approximately $ 5.8 million recorded at certain of our Canadian entities’ properties. The $ 5.8 million net deferred tax liability is comprised of a gross deferred tax liability of approximately $ 9.6 million, net of a gross deferred tax asset of approximately $ 3.8 million. The income tax benefit for the years ended December 31, 2021 and 2020 includes a deferred tax benefit of approximately $ 2.0 million and $ 5.9 million, respectively . F or the years ended December 31, 2021 and 2020, the income tax benefit was reduced by a current tax expense of approximately $ 0.2 million and $ 0.1 million, respectively. There was no material change between our expected tax rates and our actual tax rates. The Company recorded a net combined foreign, federal, and state income tax benefit of $ 1.8 million and $ 5.8 million for the year s ended December 31, 2021 and 2020, respectively, which are included in Other in our consolidated statements of operations. As of December 31, 2021 and 2020, there were unrecognized tax benefits of approximately $ 3.7 million and $ 4.1 million. These unrecognized tax benefits represent the tax benefit from the carry forward of non-capital losses at certain of our Canadian properties for Canadian income tax purposes which we have recorded a full valuation allowance against. Interest and penalties relating to uncertain tax positions will be recognized in income tax expense when incurred. As of December 31, 2021 and 2020, the Company had no interest or penalties related to uncertain tax positions. Income taxes payable are classified within accounts payable and accrued liabilities in the consolidated balance sheets. The tax years 2017-2020 remain open to examination by the major taxing jurisdictions to which we are subject.
Concentration	Concentration No single self storage customer represents a significant concentration of our revenues. For the month of December 2021, approximately 22 %, 21 %, and 11 % of our rental income was concentrated in Florida, California, and the Greater Toronto Area of Canada, respectively. Our properties within the aforementioned geographic areas are dispersed therein, operating in multiple different regions and sub-markets.
Segment Reporting	Segment Reporting Our business is comprised of two reportable segments: (i) self storage operations and (ii) the Managed REIT Platform business. Please see Note 9 – Segment Disclosures for additional detail.
Convertible Preferred Stock	Convertible Preferred Stock We classify our Series A Convertible Preferred Stock on our consolidated balance sheets using the guidance in ASC 480‑10‑S99. Our Series A Convertible Preferred Stock can be redeemed by us on or after the fifth anniversary of its issuance, or if certain events occur, such as the listing of our common stock on a national securities exchange, a change in control, or if a redemption would be required to maintain our REIT status. Additionally, if we do not maintain our REIT status the holder can require redemption. As the shares are contingently redeemable, and under certain circumstances not solely within our control, we have classified our Series A Convertible Preferred Stock as temporary equity. We have analyzed whether the conversion features in our Series A Convertible Preferred Stock should be bifurcated under the guidance in ASC 815‑10 and have determined that bifurcation is not necessary.
Per Share Data	Per Share Data Basic earnings per share attributable to our common stockholders for all periods presented are computed by dividing net income (loss) attributable to our common stockholders by the weighted average number of common shares outstanding during the period, excluding unvested restricted stock. Diluted earnings per share is computed by including the dilutive effect of the conversion of all potential common stock equivalents (which includes unvested restricted stock, convertible preferred stock, Class A and Class A-1 OP Units, and LTIP Units) and accordingly, adjusting net income to add back any changes in earnings that reduce earnings per common share in the period associated with the convertible security. For all periods presented, the dilutive effect of convertible preferred stock and unvested restricted stock was not included in the diluted weighted average shares as such impact was antidilutive. The following table presents the weighted average Class A and Class A-1 OP Units, Preferred Stock, LTIP Units, and Restricted Stock Awards, that were excluded from the computation of earnings per share as their effect would have been antidilutive: For the Year Ended December 31, 2021 2020 2019 Equivalent Shares Equivalent Shares Equivalent Shares Class A and Class A-1 OP Units 10,097,549 9,095,029 9,095,029 Series A Convertible Preferred Stock 18,761,726 14,917,110 2,428,744 LTIP Units 179,344 46,449 - Restricted Stock Awards 105,476 81,290 49,555 29,144,095 24,139,878 11,573,328
Recently Adopted/Issued Accounting Guidance	Recently Adopted Accounting Guidance In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." The new guidance changes how entities measure credit losses for most financial assets. This standard requires an entity to estimate its lifetime expected credit loss and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. In November 2018, the FASB issued ASU 2018-19, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses," which clarified that receivables arising from operating leases are within the scope of the leasing standard (ASU 2016-02), and not within the scope of ASU 2016-13. This new standard became effective on January 1, 2020. Our adoption of this standard did not have a material impact on the consolidated financial statements. Recently Issued Accounting Guidance In August 2020, the FASB issued ASU 2020-06, "Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40)." The new guidance simplifies the accounting for convertible instruments and amends the guidance for the derivatives scope exception for contracts in an entity’s own equity. Additionally, this standard amends the related earnings per share guidance. The guidance in ASU 2020-06 becomes effective for fiscal years beginning after December 15, 2021. The Company has evaluated and determined that there will be no material impact upon adoption of the new standard on its consolidated financial statements and related disclosures . In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848)." ASU 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. We continue to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur .

Summary of Fixed Rate Notes Payable	The table below summarizes our fixed rate notes payable at December 31, 2021 and 2020. The estimated fair value of financial instruments is subjective in nature and is dependent on a number of important assumptions, including discount rates and relevant comparable market information associated with each financial instrument. The fair value of the fixed rate notes payable was estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities.
