Accounting Policies [Abstract]
Organization	Note 1. Organization Strategic Storage Trust II, Inc., a Maryland corporation (the “Company”), was formed on January 8, 2013 under the Maryland General Corporation Law for the purpose of engaging in the business of investing in self storage facilities. The Company’s year-end is December 31. As used in this report, “we,” “us,” “our,” and “Company” refer to Strategic Storage Trust II, Inc. and each of our subsidiaries. SmartStop Asset Management, LLC, a Delaware limited liability company (our “Sponsor”) organized in 2013, was the sponsor of our Offering of shares of common stock, as described below. Our Sponsor is a company focused on providing real estate advisory, asset management, and property management services. Our Sponsor owns 97.5% of the economic interests (and 100% of the voting membership interests) of Strategic Storage Advisor II, LLC (our “Advisor”) and owns 100% of Strategic Storage Property Management II, LLC (our “Property Manager”). On October 1, 2015, SmartStop Self Storage, Inc. (“SmartStop”) and Extra Space Storage Inc. (“Extra Space”), along with subsidiaries of each of SmartStop and Extra Space, closed on a merger transaction (the “Extra Space Merger”) in which SmartStop was acquired by Extra Space for $13.75 per share in cash, representing an enterprise value of approximately $1.4 billion. At the closing of the Extra Space Merger, our Sponsor, which was previously owned by SmartStop, was sold to an entity controlled by H. Michael Schwartz, our Chairman of the Board of Directors and Chief Executive Officer, and became our Sponsor. The former executive management team of SmartStop continued to serve on the executive management team for our Sponsor. In addition, our management team at the time of the Extra Space Merger continues to serve on our management team, as well as the management team of our Advisor and Property Manager. We have no employees. Our Advisor, a Delaware limited liability company, was formed on January 8, 2013. Our Advisor is responsible for managing our affairs on a day-to-day basis and identifying and making acquisitions and investments on our behalf under the terms of the advisory agreement we have with our Advisor (our “Advisory Agreement”). The officers of our Advisor, as well as a majority of the officers of our Sponsor, are also officers of us. Our Articles of Amendment and Restatement, as amended, authorized 350,000,000 shares of Class A common stock, $0.001 par value per share (the “Class A Shares”) and 350,000,000 shares of Class T common stock, $0.001 par value per share (the “Class T Shares”) and 200,000,000 shares of preferred stock with a par value of $0.001. 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”). On January 10, 2014, the Securities and Exchange Commission (“SEC”) declared our registration statement effective. On May 23, 2014, we satisfied the $1.5 million minimum offering requirements of our Offering and commenced formal operations. On January 9, 2017, our Offering terminated. We sold approximately 48 million Class A Shares and approximately 7 million Class T Shares for approximately $493 million and $73 million respectively, in our Offering. On November 30, 2016, prior to the termination of our Offering, 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, 2017, we had sold approximately 1.4 million Class A Shares and approximately 0.2 million Class T Shares for approximately $13.9 million and $2.1 million, respectively, in our DRP Offering. On April 13, 2017, our board of directors, upon recommendation of our Nominating and Corporate Governance Committee, approved an estimated value per share of our common stock of $10.22 (unaudited) 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 December 31, 2016. As a result of the calculation of our estimated value per share, beginning in May 2017, shares sold pursuant to our distribution reinvestment plan are being sold at the estimated value per share of $10.22 (unaudited) for both Class A Shares and Class T Shares. Our operating partnership, Strategic Storage Operating Partnership II, L.P., a Delaware limited partnership (our “Operating Partnership”), was formed on January 9, 2013. During 2013, our 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. In conjunction with the Toronto Merger (as defined in Note 8) we issued an aggregate of approximately 483,197 Class A Units of our Operating Partnership to the common stockholders of Strategic Storage Toronto Properties REIT, Inc. (“SS Toronto”), consisting of Strategic 1031, LLC (“Strategic 1031”), a subsidiary of our Sponsor, and SS Toronto REIT Advisors, Inc., an affiliate of our Sponsor. Our Operating Partnership owns, directly or indirectly through one or more special purpose entities, all of the self storage properties that we have acquired and the self storage properties we will acquire in the future. As of December 31, 2017, we owned approximately 99.1% of the common units of limited partnership interests of our Operating Partnership. The remaining approximately 0.9% of the common units are owned by our Advisor, Strategic 1031, and SS Toronto REIT Advisors, Inc. 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 our taxable REIT subsidiary, Strategic Storage TRS II, Inc., a Delaware corporation (the “TRS”), which is a wholly-owned subsidiary of our Operating Partnership. Our Property Manager was formed on January 8, 2013 to manage our properties. Our Property Manager derives substantially all of its income from the property management services it performs for us. Our Property Manager may enter into sub-property management agreements with third party management companies and pay part of its management fee to such sub-property manager. From October 1, 2015 through September 30, 2017, our Property Manager contracted with Extra Space for Extra Space to serve as the sub-property manager for each of our properties located in the United States pursuant to separate sub-property management agreements for each property. Effective October 1, 2017, our Property Manager terminated its sub-property management agreements with Extra Space and our Property Manager began managing all of our properties in the United States directly. In connection therewith, an affiliate of our Property Manager reacquired the rights to the “SmartStop® Self Storage” brand in the United States. As a result, we began using the “SmartStop® Self Storage” brand at our United States properties effective October 1, 2017. Please see Note 8 – Related Party Transactions – Property Management Agreement. All properties owned or acquired in Canada have been and will continue to be managed by a subsidiary of our Sponsor and branded using the SmartStop® Self Storage brand. Our dealer manager is Select Capital Corporation, a California corporation (our “Dealer Manager”). Our Dealer Manager was responsible for marketing our shares offered pursuant to our Primary Offering. Our Sponsor owns a 15% non-voting equity interest in our Dealer Manager. Affiliates of our Dealer Manager own a 2.5% non-voting membership interest in our Advisor. 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 (the “Operating Partnership Agreement”). Our Advisor is prohibited from exchanging or otherwise transferring its limited partnership units so long as it is acting as our Advisor pursuant to our Advisory Agreement.

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. 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 significant intercompany accounts and transactions have been eliminated in consolidation. 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 the primary beneficiary. As of December 31, 2017 and 2016, we had not entered into any other contracts/interests that would be deemed to be variable interests in VIEs. Noncontrolling Interest in Consolidated Entities We account for the noncontrolling interest in our Operating Partnership 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 partner, our Operating Partnership, including its wholly-owned subsidiaries, are consolidated with the Company and the limited partner interest is reflected as a noncontrolling interest in the accompanying consolidated balance sheets. The noncontrolling interest shall be attributed its 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 fair value, the determination if certain entities should be consolidated, the evaluation of potential impairment of long-lived assets, 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 the property to the tangible and intangible assets acquired and the liabilities assumed based on estimated fair values. This guidance requires us to make significant estimates and assumptions, including fair value estimates, as of the acquisition date. 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. Allocations to the individual assets and liabilities are based upon comparable market sales information for land and estimates of depreciated replacement cost of equipment, building and site improvements. In allocating the purchase price, we determine whether the acquisition includes intangible assets or liabilities. 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 $4.4 million and approximately $19.9 million in intangible assets to recognize the value of in-place leases related to our acquisitions during the years ended December 31, 2017 and 2016, 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. Our acquisition-related transaction costs are required to be expensed as incurred. During the years ended December 31, 2017, 2016, and 2015 we expensed approximately $0.5 Should the initial accounting for an acquisition be incomplete by the end of a reporting period that falls within the measurement period, we will report provisional amounts in our financial statements. During the measurement period, we will 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 will record those adjustments to our consolidated financial statements. We will recognize any measurement period adjustments during the period in which we determine the amount of the adjustment to our consolidated financial statements, potentially including adjustments to interest, depreciation and amortization expense. Evaluation of Possible Impairment of Long-Lived Assets Management monitors events and changes in circumstances that could indicate that the carrying amounts of our long-lived 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 long-lived 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 long-lived assets to the fair value and recognize an impairment loss. For the years ended December 31, 2017, 2016, and 2015, no impairment losses were recognized. Revenue Recognition 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. Allowance for Doubtful Accounts Tenant accounts receivable is reported net of an allowance for doubtful accounts. Management’s estimate of the allowance is based upon a review of the current status of tenant accounts receivable. It is reasonably possible that management’s estimate of the allowance will change in the future. Real Estate Facilities Real estate facilities are recorded based on fair value as of the date of acquisition. 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 Depreciable Life Land Not Depreciated Buildings 30-35 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 are amortizing in-place lease intangibles on a straight-line basis over the estimated future benefit period. As of December 31, 2017, the gross amounts allocated to in-place lease intangibles was approximately $34.0 million and accumulated amortization of in-place lease intangibles totaled approximately $29.8 million. As of December 31, 2016, the gross amounts allocated to in-place lease intangibles was approximately $29.2 million and accumulated amortization of in-place lease intangibles totaled approximately $16.1 million. The total estimated future amortization expense of intangible assets for the years ending December 31, 2018, 2019, 2020, 2021, 2022, and thereafter is approximately $2.5 million, $0.1 million, $0.1 million, $0.1 million, $0.1 million, and $1.3 million respectively. Debt Issuance Costs The net carrying value of costs incurred in connection with our revolving credit facility are presented as debt issuance costs on our consolidated balance sheets. Debt issuance costs are amortized on a straight-line basis over the term of the related loan, which is not materially different than the effective interest method. As of December 31, 2017 and 2016, accumulated amortization of debt issuance costs related to our revolving credit facility totaled approximately $1.5 million and $0.7 million, respectively. The net carrying value of costs incurred in connection with obtaining non revolving debt are presented on the balance sheet as a deduction from secured debt (see Note 5). Debt issuance costs are amortized on a straight-line basis over the term of the related loan, which is not materially different than the effective interest method. As of December 31, 2017 and 2016, accumulated amortization of debt issuance costs related to non revolving debt totaled approximately $0.6 million and $0.2 million, respectively. Organizational and Offering Costs Our Advisor funded organization and offering costs on our behalf. We were required to reimburse our Advisor for such organization and offering costs; provided, however, our Advisor was required to reimburse us within 60 days after the end of the month in which the Offering terminated to the extent we paid or reimbursed organization and offering costs (excluding sales commissions, dealer manager fees and stockholder servicing fees) in excess of 3.5% of the gross offering proceeds from the Primary Offering. Such costs would have been recognized as a liability when we had a present responsibility to reimburse our Advisor, which is defined in our Advisory Agreement as the date we satisfied the minimum offering requirements of our Offering (which occurred on May 23, 2014). If at any point in time we determined that the total organization and offering costs were expected to exceed 3.5% of the gross proceeds anticipated to be received from the Primary Offering, we would have recognized such excess as a capital contribution from our Advisor. However, subsequent to the termination of our Primary Offering on January 9, 2017, we determined that organization and offering costs did not exceed 3.5% of the gross proceeds from the Primary Offering, and thus there was no reimbursement. Offering costs are recorded as an offset to additional paid-in capital, and organization costs are recorded as an expense. We pay our 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. 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 (i.e., excluding proceeds from sales pursuant to our distribution reinvestment plan), which calculation shall be made by us with the assistance of our 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; and (iv) the date that such Class T Share is redeemed or is no longer outstanding. Our 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 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 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 Dealer Manager, payment of attendance fees required for employees of our Dealer Manager or other affiliates to attend retail seminars and public seminars sponsored by these broker-dealers, or to defray other distribution-related expenses. Our Dealer Manager also received reimbursement of bona fide due diligence expenses; however, to the extent the due diligence expenses could not be justified, any excess over actual due diligence expenses would have been considered underwriting compensation subject to a 10% FINRA limitation and, when aggregated with all other non-accountable expenses in connection with our Public Offering, could not exceed 3% of gross offering proceeds from sales in the Public Offering. 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 related adjustments 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. Gains or losses on foreign currency transactions are recorded in other income (expense). Redeemable Common Stock We adopted a share redemption program that enables stockholders to sell their shares to us in limited circumstances. We record amounts that are redeemable under the share redemption program 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 share redemption program 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. Our redeemable common shares are contingently redeemable at the option of the holder. When we determine we have a mandatory obligation to repurchase shares under the share redemption program, we reclassify such obligations from temporary equity to a liability based upon their respective settlement values. For the year ended December 31, 2017 we received redemption requests totaling approximately $2.2 million (approximately 0.2 million shares), approximately $1.5 million of which were fulfilled during the year ended December 31, 2017, with the remaining approximately $0.7 million included in accounts payable and accrued liabilities as of December 31, 2017 and fulfilled in January 2018. For the year ended December 31, 2016 we received redemption requests totaling approximately $1.3 million, (approximately 138,000 shares), approximately $1.1 million of which were fulfilled during the year ended December 31, 2016, with the remaining approximately $0.2 million included in accounts payable and accrued liabilities as of December 31, 2016 and fulfilled in January 2017. Accounting for Equity Awards The cost of restricted stock is required to be measured based on the grant date fair value and the cost recognized over the relevant service period. 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 will 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. 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. 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, 2017 and 2016. 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, 2017 December 31, 2016 Fair Value Carrying Value Fair Value Carrying Value Fixed Rate Secured Debt $ 213,300,000 $ 218,332,483 $ 158,700,000 $ 166,410,537 As of December 31, 2017, we had interest rate swaps, an interest rate cap, and a net investment hedge (See Notes 5 and 6). 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 analysis reflected the contractual terms of the derivative, 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 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 will 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, 2017, 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 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. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. Amounts are reclassified out of other comprehensive income into earnings when the hedged net investment is either sold or substantially liquidated. 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 necessarily equal net income as calculated in accordance with GAAP). As a REIT, we generally will not be subject to 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 federal income taxes on our taxable income at regular corporate rates and will not be permitted to qualify for treatment as a REIT for 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 federal income tax purposes. Even if we continue to qualify for taxation as a REIT, we may be subject to certain state and local taxes on our income and property, and federal income and excise taxes on our undistributed income. We filed elections to treat our TRS as a taxable REIT subsidiary effective January 1, 2014. In general, the TRS performs additional services for our customers and generally engages in any real estate or non-real estate related business. The TRS is subject to corporate federal and state income tax. The TRS follows accounting guidance which requires the use of the asset and liability method. Deferred income taxes represent the tax effect of future differences between the book and tax bases of assets and liabilities. 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 shares outstanding during the period, excluding unvested restricted stock. Diluted earnings per share is computed by including the dilutive effect of unvested restricted stock, utilizing the treasury stock method. For all periods presented, the dilutive effect of unrestricted stock was not included in the diluted weighted average shares as such shares were antidilutive. Recently Issued Accounting Guidance In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers” as ASC Topic 606. The objective of ASU 2014-09 is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most of the existing revenue recognition guidance, including industry-specific guidance. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying the new standard, companies will perform a five-step analysis of transactions to determine when and how revenue is recognized. ASU 2014-09 applies to all contracts with customers except those that are within the scope of other topics in the FASB ASC. In July 2015, the FASB voted to defer the effective date by one year to annual reporting periods (including interim periods within those periods) beginning after December 15, 2017 with early adoption permitted. This ASU will be applied using the modified retrospective approach. We have determined that our self storage rental revenues will not be subject to the guidance in ASU 2014-09, as they qualify as lease contracts, which are excluded from its scope. We adopted this ASU on January 1, 2018 and its adoption did not have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 amends the guidance on accounting for leases. Under ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short term leases) at the commencement date: (1) a lease liability, which is a lessee’s obligation t

(2) Property operating income (loss) excludes corporate general and administrative expenses, asset management fees, interest expense, depreciation, amortization, and acquisition expenses. (3) Allocation based on CAD/USD exchange rates as of date of acquisition. We incurred acquisition fees to our Advisor related to the above properties of approximately $10.2 million for the year ended December 31, 2016. During 2016 we completed the purchase price allocations for our Foley, AL and Tampa, FL properties acquired in 2015 and recognized the adjustments during the third and fourth quarter of 2016 respectively. These adjustments had the aggregate impact of decreasing our allocation to land by approximately $300,000, with increases to site improvements, buildings, and intangible assets of approximately $100,000, $100,000 and $50,000 respectively. The impact of such reclassifications was that we recognized measurement period adjustments during the third and fourth quarters of 2016 to our consolidated statement of operations. This had the net impact of an increase to amortization expense of approximately $30,000 and an increase to depreciation expense of approximately $5,000 during the third quarter of 2016, and a decrease of approximately $10,000 to amortization expense and an increase to depreciation expense of $10,000 during the fourth quarter of 2016. During 2016, we also completed the purchase price allocation for the properties acquired during the first, second, and third quarters of 2016 and recognized adjustments during the fourth quarter measurement period, which had the aggregate impact of increasing our allocation to building by approximately $2.1 million, and decreasing land, site improvements, and intangible assets by approximately $0.6 million, $1.1 million, and $0.4 million respectively. The impact of such reclassifications was that we recognized measurement period adjustments during the fourth quarter of 2016 to our consolidated statement of operations, which had the net impact of a decrease to depreciation expense of approximately $40,000 and a decrease to intangible amortization expense of approximately $300,000.

(3) Canadian Dollar denominated loans shown above in USD based on the foreign exchange rate in effect as of December 31, 2017. Variable rate loans are based on Canadian Prime, or the Canadian Dealer Offered Rate (“CDOR”). (4) This loan was assumed during the acquisition of the Oakland and Concord properties, along with an interest rate swap with USAmeriBank that fixes the interest rate at 3.95%. (5) The Amended KeyBank Property Loan was repaid in full on April 11, 2017. (6) This loan encumbers 29 properties (Whittier, La Verne, Santa Ana, Upland, La Habra, Monterey Park, Huntington Beach, Chico, Lancaster I, Riverside, Fairfield, Lompoc, Santa Rosa, Federal Heights, Aurora, Littleton, Bloomingdale, Crestwood, Forestville, Warren I, Sterling Heights, Troy, Warren II, Beverly, Everett, Foley, Tampa, Boynton Beach, and Lancaster II). The separate assets of these encumbered properties are not available to pay our other debts. The equity interests in the entities that own these encumbered properties are pledged as collateral in the $11M KeyBank Subordinate Loan. See footnote 8, below. (7) This loan encumbers five properties (Pompano Beach, Lake Worth, Jupiter, Royal Palm Beach, and Delray). The separate assets of these encumbered properties are not available to pay our other debts. The equity interests in the entities that own these encumbered properties are pledged as collateral in the $11M KeyBank Subordinate Loan. See footnote 8, below. (8) This loan encumbers the equity interest in the entities that own the 34 properties (the 29 properties encumbered by the KeyBank CMBS Loan and the five properties encumbered by the KeyBank Florida CMBS Loan), and is subordinate to the existing KeyBank CMBS Loan and KeyBank Florida CMBS Loan.

(11) Canadian Dollar denominated loans shown above in USD based on the foreign exchange rate in effect as of December 31, 2017. Variable rate loans are based on Canadian Prime. (12) The Amended KeyBank Subordinate Loan (as defined below) was repaid in full on March 8, 2017. (13) We have a $90 million interest rate cap on our variable rate LIBOR based debt that caps LIBOR at 1.25%. See Note 6 below. The weighted average interest rate on our consolidated debt as of December 31, 2017 was approximately 4.3%. As of December 31, 2017 we provided recourse guarantees totaling approximately $43.7 million in connection with certain of our loans. We are subject to certain restrictive covenants relating to the outstanding debt. Amended KeyBank Credit Facility On December 22, 2015, we, through our Operating Partnership, and certain affiliated entities, entered into an amended and restated revolving credit facility (the “Amended KeyBank Credit Facility”) with KeyBank National Association (“KeyBank”), as administrative agent and KeyBanc Capital Markets, LLC, as the sole book runner and sole lead arranger, and Texas Capital Bank, N.A., and Comerica Bank as co-lenders. The Amended KeyBank Credit Facility replaced our term credit facility with KeyBank in which we had a maximum borrowing capacity of approximately $71.3 million. Under the terms of the Amended KeyBank Credit Facility, we initially had a maximum borrowing capacity of $105 million. The Amended KeyBank Credit Facility may be increased to a maximum credit facility size of $500 million, in minimum increments of $10 million, which KeyBank will arrange on a best efforts basis. On February 18, 2016, we entered into a first amendment and joinder to the amended and restated credit agreement (the “First Amendment”) with KeyBank. Under the terms of the First Amendment, we added an additional $40 million to our maximum borrowing capacity for a total of $145 million with the admission of US Bank National Association (the “Subsequent Lender”). The Subsequent Lender also became a party to the Amended KeyBank Credit Facility through a joinder agreement in the First Amendment. On March 8, 2017, we removed five of the properties held as collateral (Plantation, Wellington, Naples, Port St. Lucie II, and Doral) under the Amended KeyBank Property Loan (as defined below) and added them to the Amended KeyBank Credit Facility. In conjunction with adding these five properties to the Amended KeyBank Credit Facility, we borrowed $56 million which was used to repay approximately $46 million of principal on the Amended KeyBank Property Loan and the remaining outstanding principal balance on the Amended KeyBank Subordinate Loan of $10 million. As of December 31, 2017 we had approximately $86.4 million in borrowings outstanding under the Amended KeyBank Credit Facility. The Amended KeyBank Credit Facility is a revolving loan with an initial term of three years, maturing on December 22, 2018, with two one-year extension options subject to certain conditions outlined further in the credit agreement for the Amended KeyBank Credit Facility (the “Amended Credit Agreement”). Payments due pursuant to the Amended KeyBank Credit Facility are interest-only for the first 36 months and a 30-year amortization schedule thereafter. The Amended KeyBank Credit Facility bears interest based on the type of borrowing. The ABR Loans bear interest at the lesser of (x) the Alternate Base Rate (as defined in the Amended Credit Agreement) plus the Applicable Rate, or (y) the Maximum Rate (as defined in the Amended Credit Agreement). The Eurodollar Loans bear interest at the lesser of (a) the Adjusted LIBO Rate (as defined in the Amended Credit Agreement) for the Interest Period in effect plus the Applicable Rate, or (b) the Maximum Rate (as defined in the Amended Credit Agreement). The Applicable Rate corresponds to our total leverage, as specified in the Amended Credit Agreement. For any ABR Loans, the Applicable Rate is 125 basis points if our total leverage is less than 50%, and 150 basis points if our leverage is greater than 50%. For any Eurodollar Loan, the Applicable Rate is 225 basis points if our total leverage is less than 50% and 250 basis points if our total leverage is greater than 50%. The Amended KeyBank Credit Facility is fully recourse and is secured by cross-collateralized first mortgage liens on the mortgaged properties. The Amended KeyBank Credit Facility may be prepaid or terminated at any time without penalty, provided, however, that the Lenders (as defined in the Amended Credit Agreement) shall be indemnified for any breakage costs. Pursuant to that certain guaranty (the “KeyBank Guaranty”), dated December 22, 2015, in favor of the Lenders, we serve as a guarantor of all obligations due under the Amended KeyBank Credit Facility. Under certain conditions, the Borrower may cause the release of one or more of the properties serving as collateral for the Amended KeyBank Credit Facility, provided that no default or event of default is then outstanding or would reasonably occur as a result of such release, and after taking into account any prepayment of outstanding Loans (as defined in the Amended Credit Agreement) necessary to maintain compliance with the financial covenants. The Amended KeyBank Credit Facility contains a number of other customary terms and covenants, including the following (capitalized terms are as defined in the Amended Credit Agreement): the aggregate borrowing base availability under the Amended KeyBank Facility is limited to the lesser of: (1) 60% of the Pool Value of the properties in the collateral pool, or (2) an amount that would provide a minimum Debt Service Coverage Ratio of no less than 1.35 to 1.0; and we must meet the following financial tests, calculated as of the close of each fiscal quarter: (1) a Total Leverage Ratio of no more than 60%; (2) a Tangible Net Worth not at any time to be less than the Base Amount plus 80% of Net Equity Proceeds received after the Effective Date; (3) an Interest Coverage Ratio of no less than 1.85 to 1.0; (4) a Fixed Charge Ratio of no less than 1.6 to 1.0; (5) a ratio of varying rate Indebtedness to total Indebtedness not in excess of 30%; (6) a Loan to Value Ratio of not greater than 60%; and (7) a Debt Service Coverage Ratio of not less than 1.35 to 1.0. As of December 31, 2017 we were in compliance with all such covenants. During 2017, our Operating Partnership purchased an interest rate cap with an effective date of July 1, 2017 and a notional amount of $90 million that caps LIBOR at 1.25% through December 22, 2018. The Amended KeyBank Property Loan On March 25, 2016, one of our subsidiaries executed purchase and sale agreements with unaffiliated third parties for the acquisition of 22 self storage facilities (10 in Florida, 11 in North Carolina, and one in Maryland), two parcels of land adjacent to the North Carolina properties and one redevelopment property in North Carolina, which was subsequently assigned to Strategic Storage Growth Trust, Inc., (the “27 Property Portfolio”). On June 1, 2016 we closed on 11 self storage facilities in Florida and Maryland for approximately $275 million representing the first phase (“First Phase”) of the 27 Property Portfolio. On June 1, 2016, we, through certain affiliated entities (collectively, the “Property Loan Borrower”) entered into a credit agreement (the “Property Loan Agreement”) for a secured loan in the amount of $105 million (the “KeyBank Property Loan”) with KeyBank, as administrative agent, KeyBanc Capital Markets, LLC, as the sole book runner and sole lead arranger, and the lenders party thereto. The Property Loan Borrower borrowed $105 million in connection with the purchase of the properties in the First Phase of the 27 Property Portfolio. The KeyBank Property Loan was a term loan facility with an original maturity date of December 31, 2016. On December 29, 2016, we entered into a First Amendment to the Credit Agreement (the “First Amendment to the KeyBank Property Loan”) in connection with the KeyBank Property Loan. Prior to the First Amendment to the KeyBank Property Loan, one of the properties held as collateral was removed and added to the Amended KeyBank Credit Facility and the KeyBank Property Loan was reduced to approximately $92.8 million. The First Amendment to the KeyBank Property Loan extended the maturity date of the loan (the “Amended KeyBank Property Loan”) from December 31, 2016 to March 31, 2017. On March 8, 2017, we removed five of the properties held as collateral (Plantation, Wellington, Naples, Port St. Lucie II, and Doral) under the Amended KeyBank Property Loan and added them to the Amended KeyBank Credit Facility. On March 30, 2017 we entered into a Second Amendment to the Amended KeyBank Property Loan to extend the maturity date from March 31, 2017 to May 1, 2017. On April 11, 2017, we removed the remaining five properties that served as collateral under the Amended KeyBank Property Loan and entered into the KeyBank Florida CMBS Loan (as defined below) in which we borrowed $52 million, the proceeds of which were primarily used to pay off the outstanding balance on the A The Amended KeyBank Subordinate Loan On June 1, 2016, in conjunction with the acquisition of the First Phase of the 27 Property Portfolio, we entered into a credit agreement (the “Subordinate Loan Agreement”) in which we borrowed $30 million (the “KeyBank Subordinate Loan”) with KeyBank, as administrative agent, KeyBanc Capital Markets, LLC, as the sole book runner and sole lead arranger, and the lenders party thereto. The KeyBank Subordinate Loan was a term loan facility with an original maturity date of December 31, 2016. During the third and fourth quarters of 2016, we made payments totaling $20 million on the KeyBank Subordinate Loan, reducing the loan amount to $10 million as of December 29, 2016. On December 29, 2016, we entered into a First Amendment to the Subordinate Loan Agreement (the “First Amendment to the Subordinate Loan”), which extended the maturity date of the Subordinate Loan Agreement (subsequently, the “Amended KeyBank Subordinate Loan”) from December 31, 2016 to March 31, 2017. On March 8, 2017, we paid off the outstanding balance of $10 million on the Amended KeyBank Subordinate Loan through a draw on the Amended KeyBank Credit Facility. KeyBank CMBS Loan On July 28, 2016, we, through 29 special purpose entities wholly owned by our Operating Partnership, entered into a loan agreement with KeyBank in which we borrowed $95 million from KeyBank (the “KeyBank CMBS Loan”). Pursuant to the loan agreement, the collateral under the loan consists of our respective fee interests in 29 self storage properties (the “29 Mortgaged Properties”). The proceeds of the KeyBank CMBS Loan were primarily used to pay down our Amended KeyBank Credit Facility, after which the 29 Mortgaged Properties were released as collateral under the Amended KeyBank Credit Facility. The KeyBank CMBS Loan has an initial term of ten years, maturing on August 1, 2026. In connection with the KeyBank CMBS Loan, we entered into two promissory notes, dated July 28, 2016, in the amounts of $70 million and $25 million (the “Promissory Notes”). Monthly payments due under the Promissory Notes are interest-only for the first five years and payments reflecting a 30-year amortization schedule begin thereafter. The Promissory Notes bear interest at 3.89%. KeyBank Florida CMBS Loan On April 11, 2017, we removed the remaining five properties that served as collateral under the Amended KeyBank Property Loan and, through five special purpose entities wholly owned by our Operating Partnership, entered into a new loan agreement with KeyBank in which we borrowed $52 million (the “KeyBank Florida CMBS Loan”). Pursuant to the loan agreement, the five properties released from the Amended KeyBank Property Loan now serve as collateral under the KeyBank Florida CMBS Loan. The proceeds of the KeyBank Florida CMBS Loan were primarily used to pay off the outstanding balance on the A The KeyBank Florida CMBS Loan has an initial term of ten years, maturing on May 1, 2027. Monthly payments due are interest-only for the first five years and payments reflecting a 30-year amortization schedule begin thereafter. The loan bears interest at 4.65%. $11M KeyBank Subordinate Loan On June 1, 2017, we entered into a credit agreement (the “$11M Subordinate Loan Agreement”) in which we borrowed $11 million (the “$11M KeyBank Subordinate Loan”) with KeyBank, as administrative agent, KeyBanc Capital Markets, LLC, as the sole book runner and sole lead arranger, and the lenders party thereto. This loan is subordinate to the existing KeyBank CMBS Loan and the KeyBank Florida CMBS Loan, and encumbers the same 34 properties already encumbered by these two loans. The $11M KeyBank Subordinate Loan has an initial term of three years, maturing on June 1, 2020, with a one-year extension option subject to certain conditions in the credit agreement. The $11M KeyBank Subordinate Loan bears interest based on the type of borrowing elected by us. An ABR Borrowing bears interest at the lesser of (x) the Alternate Base Rate (as defined in the $11M Subordinate Loan Agreement) plus the Applicable Rate, or (y) the Maximum Rate (as defined in the $11M Subordinate Loan Agreement). A Eurodollar Borrowing bears interest at the lesser of (a) the Adjusted LIBO Rate (as defined in the $11M Subordinate Loan Agreement) for the Interest Period in effect plus the Applicable Rate, or (b) the Maximum Rate (as defined in the $11M Subordinate Loan Agreement). The Applicable Rate means 375 basis points for any Eurodollar Borrowing and 275 basis points for any ABR Borrowing. The proceeds from the $11M KeyBank Subordinate Loan were primarily used to pay down the Amended KeyBank Credit Facility.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments	Note 6. Derivative Instruments Interest 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 (“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 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 derivatives not designated in hedging relationships are recorded in other income (expense) as income within our consolidated statements of operations and were approximately $290,000 for the year ended December 31, 2017. Foreign Currency Forward 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 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. 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 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, 2017: Notional Amount Strike Effective Date or Date Assumed Maturity Date Interest Rate Swaps: Oakland and Concord loan $ 19,960,190 3.95 % May 18, 2016 April 10, 2023 Dufferin loan 14,025,000 (1) 3.21 % February 1, 2017 May 31, 2019 Mavis loan 11,821,000 (1) 3.21 % February 1, 2017 May 31, 2019 Brewster loan 7,726,000 (1) 3.21 % February 1, 2017 May 31, 2019 Interest Rate Cap: LIBOR $ 90,000,000 1.25 % July 1, 2017 December 22, 2018 Foreign Currency Forward: Denominated in CAD $ 101,000,000 (1) 1.2526 August 31, 2017 March 29, 2018 (1) Notional amounts shown are denominated in CAD. On February 1, 2017, to hedge our net investment related to the Toronto Merger, we entered into a foreign currency forward contract with a notional amount of $58.5 million CAD, and a forward rate of approximately 1.3058. During the quarter ended March 31, 2017, we settled our two foreign currency forward contracts which resulted in us receiving a net settlement of approximately $1.4 million, and simultaneously entered into a third foreign currency forward contract with a notional amount of $101 million CAD, and a forward rate of approximately 1.3439. During the quarter ended September 30, 2017, we settled our third foreign currency forward contract, which resulted in us paying a net settlement of approximately $5.5 million, and simultaneously entered into a fourth foreign currency forward contract as noted in the table above. A portion of our gain (loss) from our settled hedges is recorded net in foreign currency forward contract gain (loss) in our consolidated statements of comprehensive loss, and a loss of approximately $125,000 related to the ineffective portion is recorded in other income (expense) within our consolidated statements of operations for the year ended December 31, 2017.

Equity [Abstract]
Preferred Equity	Note 7. Preferred Equity Issuance of Preferred Units by our Operating Partnership On November 3, 2014, we and our Operating Partnership entered into a Series A Cumulative Redeemable Preferred Unit Purchase Agreement (the “Unit Purchase Agreement”) with the Preferred Investor, a wholly-owned subsidiary of SmartStop Self Storage Operating Partnership, L.P. Pursuant to the Unit Purchase Agreement, the Preferred Investor agreed to provide up to $65 million through a preferred equity investment in our Operating Partnership (the “Preferred Equity Investment”), to be used solely for investments in self storage properties, as described in the underlying documents, in exchange for up to 2.6 million preferred units of limited partnership interest of our Operating Partnership (the “Preferred Units”), each having a liquidation preference of $25.00 per Preferred Unit (the “Liquidation Amount”), plus all accumulated and unpaid distributions. In addition to the Unit Purchase Agreement, we and our Operating Partnership entered into a Second Amended and Restated Limited Partnership Agreement of the Operating Partnership (the “Second Amended and Restated Limited Partnership Agreement”) and Amendment No. 1 to the Second Amended and Restated Limited Partnership Agreement (the “Amendment”). The Second Amended and Restated Limited Partnership Agreement authorizes the issuance of additional classes of units of limited partnership interest in the Operating Partnership, establishes a new series of preferred units of limited partnership interest in the Operating Partnership and sets forth other necessary corresponding changes. All other terms of the Second Amended and Restated Limited Partnership Agreement remained substantially the same. The Amendment sets forth key terms of the Preferred Units, some of which are discussed below. In a number of transactions, the Preferred Investor invested a total of $59.5 million in our Operating Partnership and was issued approximately 2.4 million preferred units. As of December 31, 2015, we had redeemed all of the Preferred Units. The holders of the Preferred Units received current distributions (the “Current Distributions”) at a rate of a one-month LIBOR plus 6.5% per annum on the Liquidation Amount, payable monthly and calculated on an actual/360 basis. In addition to the Current Distributions, our Operating Partnership had the obligation to elect either (A) to pay the holder of the Preferred Units additional distributions monthly in an amount equal to: (i) 4.35% per annum of the Liquidation Amount through March 31, 2017; and (ii) beginning April 1, 2017, 6.35% per annum of the Liquidation Amount or (B) defer the additional distributions ( the “Deferred Distributions”) in an amount that accumulated monthly in an amount equal to (i) LIBOR plus 10.85% of the Deferred Distributions through March 31, 2017; and (ii) beginning April 1, 2017, LIBOR plus 12.85% of the Deferred Distributions.

Related Party Transactions [Abstract]
Related Party Transactions	Note 8. Related Party Transactions Fees to Affiliates Our Advisory Agreement with our Advisor and dealer manager agreement, as amended (“Dealer Manager Agreement”) with our Dealer Manager entitle our Advisor and our Dealer Manager to specified fees upon the provision of certain services with regard to the Offering and investment of funds in real estate properties, among other services, as well as reimbursement for organization and offering costs incurred by our Advisor on our behalf and reimbursement of certain costs and expenses incurred by our Advisor in providing services to us. Organization and Offering Costs Organization and offering costs of the Offering could be paid by our Advisor on our behalf and were reimbursed to our Advisor from the proceeds of our Offering. Organization and offering costs consist of all expenses (other than sales commissions, the dealer manager fees and stockholder servicing fees) paid by us in connection with the Offering, including our legal, accounting, printing, mailing and filing fees, charges of our escrow holder and other accountable organization and offering expenses, including, but not limited to, (i) amounts to reimburse our Advisor for all marketing related costs and expenses such as salaries and direct expenses of employees of our Advisor and its affiliates in connection with registering and marketing our shares; (ii) technology costs associated with the Offering; (iii) our costs of conducting our training and education meetings; (iv) our costs of attending retail seminars conducted by participating broker-dealers; and (v) payment or reimbursement of bona fide due diligence expenses. Our Advisor was obligated to reimburse us within 60 days after the end of the month which the Offering terminated to the extent we paid or reimbursed organization and offering costs (excluding sales commissions, dealer manager fees, and stockholder servicing fees) in excess of 3.5% of the gross offering proceeds from the Primary Offering. However, subsequent to the termination of our Primary Offering on January 9, 2017, we determined that organization and offering costs did not exceed 3.5% of the gross proceeds from the Primary Offering, and thus there was no reimbursement. Advisory Agreement We do not have any employees. Our Advisor is primarily responsible for managing our business affairs and carrying out the directives of our board of directors. Our Advisor receives various fees and expenses under the terms of our Advisory Agreement. As noted above, we were required under our Advisory Agreement to reimburse our Advisor for organization and offering costs. Our Advisory Agreement also required our Advisor to reimburse us to the extent that offering expenses, including sales commissions, dealer manager fees, stockholder servicing fees and organization and offering expenses, were in excess of 15% of gross proceeds from the Offering. However, subsequent to the termination of our Primary Offering on January 9, 2017, we determined offering expenses were not in excess of 15% of gross proceeds from the Offering, and thus there was no reimbursement. Our Advisor receives acquisition fees equal to 1.75% of the contract purchase price of each property we acquire plus reimbursement of any acquisition expenses incurred by our Advisor. Our Advisor also receives a monthly asset management fee equal to 0.05208%, which is one-twelfth of 0.625%, of our aggregate asset value, as defined in the Advisory Agreement. Under our Advisory Agreement, our Advisor receives disposition fees in an amount equal to the lesser of (i) one-half of the competitive real estate commission or (ii) 1% of the contract sale price for each property we sell, as long as our Advisor provides substantial assistance in connection with the sale. The total real estate commissions paid (including the disposition fee paid to our Advisor) may not exceed the lesser of a competitive real estate commission or an amount equal to 6% of the contract sale price of the property. Our Advisor is also entitled to various subordinated distributions pursuant to our Operating Partnership Agreement if we (1) list our shares of common stock on a national exchange, (2) terminate our Advisory Agreement (other than a voluntary termination), (3) liquidate our portfolio, or (4) enter into an Extraordinary Transaction, as defined in the Operating Partnership Agreement. Our Advisory Agreement provides for reimbursement of our Advisor’s direct and indirect costs of providing administrative and management services to us. Pursuant to the Advisory Agreement, our Advisor is obligated to pay or reimburse us the amount by which our aggregate annual operating expenses, as defined, exceed the greater of 2% of our average invested assets or 25% of our net income, as defined, unless a majority of our independent directors determine that such excess expenses were justified based on unusual and non-recurring factors. For any fiscal quarter for which total operating expenses for the 12 months then ended exceed the limitation, we will disclose this fact in our next quarterly report or within 60 days of the end of that quarter and send a written disclosure of this fact to our stockholders. In each case the disclosure will include an explanation of the factors that the independent directors considered in arriving at the conclusion that the excess expenses were justified. For the years ended December 31, 2015, 2016, and 2017, our aggregate annual operating expenses, as defined, did not exceed the thresholds described above. Dealer Manager Agreement Our 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 Dealer Manager Agreement. In addition, our Dealer Manager receives 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. 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 (i.e., excluding proceeds from sales pursuant to our distribution reinvestment plan), which calculation shall be made by us with the assistance of our 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; and (iv) the date that such Class T Share is redeemed or is no longer outstanding. Our 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 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 Dealer Manager could also 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 Dealer Manager, payment of attendance fees required for employees of our Dealer Manager or other affiliates to attend retail seminars and public seminars sponsored by these broker-dealers, or to defray other distribution-related expenses. Our Dealer Manager also received reimbursement of bona fide due diligence expenses; however, to the extent these due diligence expenses could not be justified, any excess over actual due diligence expenses would have been considered underwriting compensation subject to a 10% FINRA limitation and, when aggregated with all other non-accountable expenses in connection with our Offering, could not exceed 3% of gross offering proceeds from sales in the Offering. Affiliated Dealer Manager Our Sponsor owns a 15% non-voting equity interest in our Dealer Manager. Affiliates of our Dealer Manager own a 2.5% non-voting membership interest in our Advisor. Property Management Agreement Since inception, our Property Manager has served as the property manager for each of our properties pursuant to separate property management agreements. From October 1, 2015 through September 30, 2017, our Property Manager contracted with Extra Space for Extra Space to serve as the sub-property manager for each of our properties located in the United States pursuant to separate sub-property management agreements for each property. Effective October 1, 2017, our Property Manager terminated its sub-property management agreements with Extra Space. Our Property Manager now manages all our properties directly. In addition, an affiliate of our Property Manager reacquired the rights to the “SmartStop ® ® Prior Arrangement Under the property management agreements in effect from October 1, 2015 through September 30, 2017 for our properties located in the United States, our Property Manager received a monthly management fee for each property equal to the greater of $2,500 or 6% of the gross revenues, plus reimbursement of our Property Manager’s costs of managing the properties. In addition, Extra Space agreed to pay up to $25,000 per property toward the signage and set-up costs associated with converting such property to the Extra Space brand (the “Set-Up Amount”). The property management agreements had a three year term and automatically renewed for successive one year periods thereafter, unless we or our Property Manager provided prior written notice at least 90 days prior to the expiration of the term. In general, if we terminated a property management agreement without cause during the initial three year term, we would have been required to pay our Property Manager a termination fee equal to the Set-Up Amount, reduced by 1/36th of the Set-Up Amount for every full month of the term that had elapsed. After the end of the initial three year term, we could have terminated a property management agreement on 30 days prior written notice without payment of a termination fee. Our Property Manager could have terminated a property management agreement on 60 days prior written notice to us. The sub-property management agreements between our Property Manager and Extra Space were substantially the same as the foregoing property management agreements. Under the sub-property management agreements, our Property Manager paid Extra Space a monthly management fee for each property equal to the greater of $2,500 or 6% of the gross revenues, plus reimbursement of Extra Space’s costs of managing the properties; provided, however that no management fee was due and payable to Extra Space for the months of January and July each year during the term. Extra Space had the exclusive right to offer tenant insurance to the tenants and was entitled to all of the benefits of such tenant insurance. The sub-property management agreements also had a three year term and automatically renewed for successive one year periods thereafter, unless our Property Manager or Extra Space provided prior written notice at least 90 days prior to the expiration of the term. In general, if our Property Manager terminated a sub-property management agreement without cause during the initial three year term, it would have been required to pay Extra Space a termination fee equal to the Set-Up Amount, reduced by 1/36th of the Set-Up Amount for every full month of the term that had elapsed. After the end of the initial three year term, our Property Manager could have terminated a sub-property management agreement on 30 days prior written notice without payment of a termination fee. Extra Space could have terminated a sub-property management agreement on 60 days prior written notice to our Property Manager. Termination of Sub-property Manager As of October 1, 2017, our Property Manager terminated each sub-property management agreement with Extra Space, and we amended each of our corresponding property management agreements as described below. To the extent a termination fee would have been owed by any of our property-owning subsidiaries had its corresponding property management agreement with our Property Manager been terminated, each such property-owning subsidiary agreed to pay the termination fee owed by our Property Manager in accordance with its termination of the sub-property management agreements. The aggregate costs incurred in connection with the property management changes were approximately $0.8 million. This amount was included in property operating expenses – affiliates in the accompanying consolidated statements of operations for the year ended December 31, 2017. Property Management Subsequent to September 30, 2017 In connection with the termination of each sub-property management agreement, each corresponding property management agreement was amended effective as of October 1, 2017. Pursuant to the amended property management agreements, our Property Manager receives: (i) a monthly management fee for each property equal to the greater of $3,000 or 6% of the gross revenues from the properties plus reimbursement of the Property Manager’s costs of managing the properties and (ii) a construction management fee equal to 5% of the cost of construction or capital improvement work in excess of $10,000. In addition, we have agreed with our Property Manager or an affiliate to share equally in the net revenue attributable to the sale of tenant insurance at our properties. The property management agreements have a three year term and automatically renew for successive three year periods thereafter, unless we or our Property Manager provide prior written notice at least 90 days prior to the expiration of the term. After the end of the initial three year term, either party may terminate a property management agreement generally upon 60 days prior written notice. With respect to each new property we acquire for which we enter into a property management agreement with our Property Manager we will also pay our Property Manager a one-time start-up fee in the amount of $3,750. In connection with the change in our property management operations, each of our stores in the United States were rebranded under the “SmartStop® Self Storage” brand. Our self storage properties located in Canada are subject to separate property management agreements with our Property Manager on terms substantially the same as the amended property management agreements described above. 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, 2016 and 2017, and any related amounts payable as of December 31, 2016 and 2017: Year Ended December 31, 2016 Year Ended December 31, 2017 Incurred Paid Payable Incurred Paid Payable Expensed Operating expenses (including organizational costs) $ 735,891 $ 777,354 $ 6,508 $ 1,090,366 $ 751,010 $ 345,864 Asset management fees 2,970,846 2,970,846 — 5,346,280 5,346,280 — Property management fees (1) 2,752,862 2,752,862 — 5,285,082 5,285,082 — Acquisition expenses 10,729,535 10,729,535 — 212,577 212,577 — Additional Paid-in Capital — — — Selling commissions 21,141,748 21,141,748 — 966,516 966,516 — Dealer Manager fee 6,573,962 6,573,760 160,714 353,167 513,881 — Stockholder servicing fee (2) 3,297,305 286,292 3,011,013 299,299 690,272 2,620,040 Offering costs 444,719 444,719 — 33,466 33,466 — Total $ 48,646,868 $ 45,677,116 $ 3,178,235 $ 13,586,753 $ 13,799,084 $ 2,965,904 (1) During the years ended December 31, 2017 and 2016, property management fees included approximately $3.2 million and $2.2 million, respectively, of fees paid to the sub-property manager of our properties. This includes the costs incurred related to the change in property management of approximately $0.8 million during 2017. (2) We pay our Dealer Manager an ongoing stockholder servicing fee that is payable monthly and accrues daily in an amount equal to 1/365 th Extra Space Self Storage In connection with the Extra Space Merger of SmartStop Self Storage, Inc. into Extra Space, certain of our executive officers, including H. Michael Schwartz, Paula Mathews, Michael McClure and James Berg, received units of limited partnership interest in Extra Space Storage LP, the operating partnership for Extra Space, in exchange for units of limited partnership of SmartStop Self Storage Operating Partnership, L.P., the operating partnership for SmartStop, owned by such executives. Tenant Insurance We offer a tenant insurance plan to customers at our properties pursuant to which we receive 50% of the net revenues generated from such tenant insurance and our Property Manager or an affiliate receives the other 50% of such net revenues. Storage Auction Program In March 2017, our Sponsor acquired a minority interest in a company (the “Auction Company”) that serves as a web portal for self storage companies to post their auctions for the contents of abandoned storage units online instead of using live auctions conducted at the self storage facilities. The Auction Company is expected to receive a service fee for such services. Through December 31, 2017, neither our Property Manager nor our sub-property manager utilized the Auction Company at our properties. Our Property Manager may in the future utilize the Auction Company, and we would be responsible for paying any fees related to our properties. Our properties would receive the proceeds from such online auctions. Toronto Merger On February 1, 2017, we entered into a definitive Agreement and Plan of Merger (the “Toronto Merger Agreement”) pursuant to which SST II Toronto Acquisition, LLC, a wholly owned and newly formed subsidiary of our Operating Partnership, merged (the “Toronto Merger”) with and into SS Toronto, a subsidiary of our Sponsor, with SS Toronto surviving the Toronto Merger and becoming a wholly owned subsidiary of our Operating Partnership. In connection with the Toronto Merger, we acquired five self storage properties located in the Greater Toronto Areas of North York, Mississauga, Brampton, Pickering and Scarborough (the “SS Toronto Properties”). Each property is operated under the “SmartStop” brand. At the effective time of the Toronto Merger, each share of common stock, $0.001 par value per share, of SS Toronto issued and outstanding was automatically converted into the right to receive $11.0651 USD in cash and 0.7311 Class A Units of our Operating Partnership. We paid an aggregate of approximately $7.3 million USD in cash consideration and issued an aggregate of approximately 483,197 Class A Units of our Operating Partnership to the common stockholders of SS Toronto, consisting of Strategic 1031 and SS Toronto REIT Advisors, Inc., affiliates of our Sponsor. We acquired the SS Toronto Properties subject to approximately $50.1 million CAD (approximately $38.4 million USD) in outstanding debt (as described further below), approximately $0.8 million in other net liabilities, and paid approximately $33.1 million USD to an affiliate of Extra Space as repayment of outstanding debt and accrued interest owed by SS Toronto. No acquisition fee was paid to our Advisor for the Toronto Merger. The terms of the Toronto Merger and the execution of the Toronto Merger Agreement were recommended by a special committee (the “Special Committee”) of our board of directors consisting of the Nominating and Corporate Governance Committee, the members of which were all of our independent directors. The Special Committee, with the assistance of its independent financial advisor and independent legal counsel, approved the transaction and determined that the Toronto Merger and the other transactions contemplated by the Toronto Merger Agreement were advisable and in the best interests of us, were fair and reasonable to us and were on terms and conditions not less favorable to us than those available from unaffiliated third parties. In connection with the Toronto Merger, we entered into guarantees, dated as of February 1, 2017 (the “Guarantees”), under which we agreed to guarantee certain obligations of SS Toronto. The SS Toronto loans consist of (i) term loans totaling approximately $34.8 million CAD pursuant to promissory notes executed by SS Toronto in favor of Bank of Montreal on June 3, 2016, and (ii) mortgage financings in the aggregate amount of up to $17.7 million CAD pursuant to two promissory notes executed by subsidiaries of SS Toronto in favor of DUCA Financial Services Credit Union Ltd. on June 3, 2016.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 9. 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 April 13, 2017, beginning in May 2017, shares sold pursuant to our distribution reinvestment plan are sold at the new estimated value per share of $10.22 per Class A Share and Class T Share. 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, 2017, we had sold approximately 1.4 million Class A Shares and approximately 0.2 million Class T Shares through our DRP Offering. Share Redemption Program We adopted a share redemption program that enables stockholders to sell their shares to us in limited circumstances. As long as our common stock is not listed on a national securities exchange or over-the-counter market, our stockholders who have held their stock for at least one year may be able to have all or any portion of their shares of stock redeemed by us. We may redeem the shares of stock presented for redemption for cash to the extent that we have sufficient funds available to fund such redemption. Our board of directors may amend, suspend or terminate the share redemption program 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. The complete terms of our share redemption program are described in our prospectus. The amount that we may pay to redeem stock for redemptions is the redemption price set forth in the following table which is based upon the number of years the stock is held: Number Years Held Redemption Price Less than 1 No Redemption Allowed 1 or more but less than 3 90.0% of Redemption Amount 3 or more but less than 4 95.0% of Redemption Amount 4 or more 100.0% of Redemption Amount At any time we are engaged in an offering of shares, the Redemption Amount for shares purchased under our share redemption program will always be equal to or lower than the applicable per share offering price. As long as we are engaged in an offering, the Redemption Amount shall be the lesser of the amount the stockholder paid for their shares or the price per share in the current offering. If we are no longer engaged in an offering, our board of directors will announce any redemption price adjustment and the time period of its effectiveness as a part of its regular communications with our stockholders. At any time the redemption price during an offering is determined by any method other than the offering price, if we have sold property and have made one or more special distributions to our stockholders of all or a portion of the net proceeds from such sales, the per share redemption price will be reduced by the net sale proceeds per share distributed to investors prior to the redemption date as a result of the sale of such property in the special distribution. Our board of directors will, in its sole discretion, determine which distributions, if any, constitute a special distribution. While our board of directors does not have specific criteria for determining a special distribution, we expect that a special distribution will only occur upon the sale of a property and the subsequent distribution of the net sale proceeds. There are several limitations on our ability to redeem shares under the share redemption program including, but not limited to: • Unless the shares are being redeemed in connection with a stockholder’s death, “qualifying disability” (as defined under the share redemption program) or bankruptcy, we may not redeem shares until the stockholder has held his or her shares for one year. • 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, 2017, we received redemption requests totaling approximately $2.2 million (approximately 0.2 million shares), approximately $1.5 million of which were fulfilled during year ended December 31, 2017, with the remaining approximately $0.7 million included in accounts payable and accrued liabilities as of December 31, 2017 and fulfilled in January 2018. For the year ended December 31, 2016 we received redemption requests totaling approximately $1.3 million (approximately 138,000 shares), approximately $1.1 million of which were fulfilled during year ended December 31, 2016, with the remaining approximately $0.2 million included in accounts payable and accrued liabilities as of December 31, 2016 and fulfilled in January 2017. Operating Partnership Redemption Rights The limited partners of our Operating Partnership 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. Our Advisor is prohibited from exchanging or otherwise transferring its limited partnership units so long as our Advisor is acting as our advisor under the Advisory Agreement. Other Contingencies From time to time, we are party to legal proceedings that arise in the ordinary course of our business. We are not aware of any legal proceedings of which the outcome is reasonably likely to have a material adverse effect on our results of operations or financial condition, nor are we aware of any such legal proceedings contemplated by governmental authorities.

During 2016 we completed the purchase price allocations for our Foley, AL and Tampa, FL properties acquired in 2015 and 33 properties acquired in 2016 and recognized the measurement period adjustments in our consolidated statement of operations during the fourth quarter of 2016. If such measurement period adjustments were retroactively recorded they would have had the net impact of increasing depreciation expense by approximately $400, and $3,000 for the third and fourth quarters of 2015, respectively, and decreasing depreciation expense by approximately $9,000, $9,000, and $10,000 for the first, second, and third quarters of 2016, respectively. Intangible amortization expense would have had the net impact of increasing by approximately $2,000 and $8,000 for the third and fourth quarters of 2015, respectively, and decreasing amortization expense by approximately $40,000, $120,000, and $130,000 for the first, second, and third quarters of 2016, respectively. However, with the adoption of amended accounting guidance, the cumulative measurement period adjustments were recorded in the fourth quarter of 2016.

Subsequent Events	Note 12. Subsequent Events Distribution Declaration On March 20, 2018, our board of directors declared a distribution rate for the second quarter of 2018 of $0.001644 per day per share on the outstanding shares of common stock payable to both Class A and Class T stockholders of record of such shares as shown on our books at the close of business on each day during the period, commencing on April 1, 2018 and continuing on each day thereafter through and including June 30, 2018. Such distributions payable to each stockholder of record during a month will be paid the following month. Joint Venture with SmartCentres In January 2018, a subsidiary of our Sponsor entered into a contribution agreement (“Contribution Agreement”) with a subsidiary of SmartCentres Real Estate Investment Trust, an unaffiliated third party (“SmartCentres”), for a tract of land owned by SmartCentres and located in East York, Ontario (the “East York Lot”) in Canada. In March, 2018, the interest in the Contribution Agreement was assigned to one of our subsidiaries. Upon closing, the East York Lot will be owned by a limited partnership (the “Limited Partnership”), in which we (through our subsidiaries) and SmartCentres (through its subsidiaries) will each be a 50% limited partner and each have an equal ranking general partner in the Limited Partnership. It is intended that the Limited Partnership develops a self storage facility on the East York Lot. The value of the land to be contributed by SmartCentres to the Limited Partnership has an agreed upon fair market value of approximately $7.6 million CAD. At closing, we will subscribe for 50% of the units in the Limited Partnership at an agreed upon subscription price of approximately $3.8 million CAD, representing a contribution equivalent to 50% of the agreed upon fair market value of the land. We expect the acquisition of the East York Lot to close in the third quarter of 2018 after the land has been zoned so as to permit the self storage facility. In some circumstances, if we fail to complete the acquisition, we may forfeit up to approximately $0.3 million CAD in earnest money. Tenant Insurance Joint Venture In connection with the amended property management agreements effective as of October 1, 2017, we agreed with our Property Manager to share equally in the net revenue attributable to the sale of tenant insurance at our properties. On March 19, 2018, to facilitate such revenue sharing, we and our Property Manager agreed to transfer our respective rights in such tenant insurance revenue to a newly created joint venture (the “TI Joint Venture”), Strategic Storage TI Services II JV, LLC (the “TI Joint Venture Entity”), a Delaware limited liability company, which is owned 50% by our TRS subsidiary and 50% by our Property Manager’s affiliate, SmartStop TI II, LLC (“SS TI II”). Under the terms of the TI Joint Venture agreement, our TRS receives 50% of the net economics generated from such tenant insurance and SS TI II receives the other 50%. The TI Joint Venture agreement further provides, among other things, that if a member or its affiliate terminates all or substantially all of the property management agreements or defaults in its material obligations under the TI Joint Venture agreement or undergoes a change of control (the “Triggering Member”), the other member generally shall have the right (but not the obligation) to either (i) sell its 50% interest in the TI Joint Venture Entity to the Triggering Member at fair market value (as agreed upon or as determined under an appraisal process) or (ii) purchase the Triggering Member’s 50% interest in the TI Joint Venture Entity at 95% of fair market value. Foreign Currency Hedging Activity On March 28, 2018 we settled our foreign currency forward which resulted in us receiving a settlement of approximately $2.2 million. In conjunction with the settlement, we entered into a new forward contract to continue hedging our net Canadian investment. The new forward contract has a notional amount of $90 million CAD, a maturity date of January 28, 2019, and a forward rate of approximately 1.2846. Distribution Reinvestment Plan Offering Status As of March 23, 2018, in connection with our DRP Offering, we had issued approximately 1.7 million Class A shares of our common stock and approximately 0.3 million Class T Shares of our common stock for gross proceeds of approximately $17.3 million and approximately $2.6 million, respectively.

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.
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 significant intercompany accounts and transactions have been eliminated in consolidation.
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 the primary beneficiary. As of December 31, 2017 and 2016, we had not entered into any other contracts/interests that would be deemed to be variable interests in VIEs.
Noncontrolling Interest in Consolidated Entities	Noncontrolling Interest in Consolidated Entities We account for the noncontrolling interest in our Operating Partnership 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 partner, our Operating Partnership, including its wholly-owned subsidiaries, are consolidated with the Company and the limited partner interest is reflected as a noncontrolling interest in the accompanying consolidated balance sheets. The noncontrolling interest shall be attributed its 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 fair value, the determination if certain entities should be consolidated, the evaluation of potential impairment of long-lived assets, 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 the property to the tangible and intangible assets acquired and the liabilities assumed based on estimated fair values. This guidance requires us to make significant estimates and assumptions, including fair value estimates, as of the acquisition date. 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. Allocations to the individual assets and liabilities are based upon comparable market sales information for land and estimates of depreciated replacement cost of equipment, building and site improvements. In allocating the purchase price, we determine whether the acquisition includes intangible assets or liabilities. 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 $4.4 million and approximately $19.9 million in intangible assets to recognize the value of in-place leases related to our acquisitions during the years ended December 31, 2017 and 2016, 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. Our acquisition-related transaction costs are required to be expensed as incurred. During the years ended December 31, 2017, 2016, and 2015 we expensed approximately $0.5 Should the initial accounting for an acquisition be incomplete by the end of a reporting period that falls within the measurement period, we will report provisional amounts in our financial statements. During the measurement period, we will 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 will record those adjustments to our consolidated financial statements. We will recognize any measurement period adjustments during the period in which we determine the amount of the adjustment to our consolidated financial statements, potentially including adjustments to interest, depreciation and amortization expense.
Evaluation of Possible Impairment of Long-Lived Assets	Evaluation of Possible Impairment of Long-Lived Assets Management monitors events and changes in circumstances that could indicate that the carrying amounts of our long-lived 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 long-lived 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 long-lived assets to the fair value and recognize an impairment loss. For the years ended December 31, 2017, 2016, and 2015, no impairment losses were recognized.
Revenue Recognition	Revenue Recognition 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.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts Tenant accounts receivable is reported net of an allowance for doubtful accounts. Management’s estimate of the allowance is based upon a review of the current status of tenant accounts receivable. It is reasonably possible that management’s estimate of the allowance will change in the future.
Real Estate Facilities	Real Estate Facilities Real estate facilities are recorded based on fair value as of the date of acquisition. 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 Depreciable Life Land Not Depreciated Buildings 30-35 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 are amortizing in-place lease intangibles on a straight-line basis over the estimated future benefit period. As of December 31, 2017, the gross amounts allocated to in-place lease intangibles was approximately $34.0 million and accumulated amortization of in-place lease intangibles totaled approximately $29.8 million. As of December 31, 2016, the gross amounts allocated to in-place lease intangibles was approximately $29.2 million and accumulated amortization of in-place lease intangibles totaled approximately $16.1 million. The total estimated future amortization expense of intangible assets for the years ending December 31, 2018, 2019, 2020, 2021, 2022, and thereafter is approximately $2.5 million, $0.1 million, $0.1 million, $0.1 million, $0.1 million, and $1.3 million respectively.
Debt Issuance Costs	Debt Issuance Costs The net carrying value of costs incurred in connection with our revolving credit facility are presented as debt issuance costs on our consolidated balance sheets. Debt issuance costs are amortized on a straight-line basis over the term of the related loan, which is not materially different than the effective interest method. As of December 31, 2017 and 2016, accumulated amortization of debt issuance costs related to our revolving credit facility totaled approximately $1.5 million and $0.7 million, respectively. The net carrying value of costs incurred in connection with obtaining non revolving debt are presented on the balance sheet as a deduction from secured debt (see Note 5). Debt issuance costs are amortized on a straight-line basis over the term of the related loan, which is not materially different than the effective interest method. As of December 31, 2017 and 2016, accumulated amortization of debt issuance costs related to non revolving debt totaled approximately $0.6 million and $0.2 million, respectively.
Organizational and Offering Costs	Organizational and Offering Costs Our Advisor funded organization and offering costs on our behalf. We were required to reimburse our Advisor for such organization and offering costs; provided, however, our Advisor was required to reimburse us within 60 days after the end of the month in which the Offering terminated to the extent we paid or reimbursed organization and offering costs (excluding sales commissions, dealer manager fees and stockholder servicing fees) in excess of 3.5% of the gross offering proceeds from the Primary Offering. Such costs would have been recognized as a liability when we had a present responsibility to reimburse our Advisor, which is defined in our Advisory Agreement as the date we satisfied the minimum offering requirements of our Offering (which occurred on May 23, 2014). If at any point in time we determined that the total organization and offering costs were expected to exceed 3.5% of the gross proceeds anticipated to be received from the Primary Offering, we would have recognized such excess as a capital contribution from our Advisor. However, subsequent to the termination of our Primary Offering on January 9, 2017, we determined that organization and offering costs did not exceed 3.5% of the gross proceeds from the Primary Offering, and thus there was no reimbursement. Offering costs are recorded as an offset to additional paid-in capital, and organization costs are recorded as an expense. We pay our 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. 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 (i.e., excluding proceeds from sales pursuant to our distribution reinvestment plan), which calculation shall be made by us with the assistance of our 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; and (iv) the date that such Class T Share is redeemed or is no longer outstanding. Our 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 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 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 Dealer Manager, payment of attendance fees required for employees of our Dealer Manager or other affiliates to attend retail seminars and public seminars sponsored by these broker-dealers, or to defray other distribution-related expenses. Our Dealer Manager also received reimbursement of bona fide due diligence expenses; however, to the extent the due diligence expenses could not be justified, any excess over actual due diligence expenses would have been considered underwriting compensation subject to a 10% FINRA limitation and, when aggregated with all other non-accountable expenses in connection with our Public Offering, could not exceed 3% of gross offering proceeds from sales in the Public Offering. 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 related adjustments 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. Gains or losses on foreign currency transactions are recorded in other income (expense).
Redeemable Common Stock	Redeemable Common Stock We adopted a share redemption program that enables stockholders to sell their shares to us in limited circumstances. We record amounts that are redeemable under the share redemption program 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 share redemption program 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. Our redeemable common shares are contingently redeemable at the option of the holder. When we determine we have a mandatory obligation to repurchase shares under the share redemption program, we reclassify such obligations from temporary equity to a liability based upon their respective settlement values. For the year ended December 31, 2017 we received redemption requests totaling approximately $2.2 million (approximately 0.2 million shares), approximately $1.5 million of which were fulfilled during the year ended December 31, 2017, with the remaining approximately $0.7 million included in accounts payable and accrued liabilities as of December 31, 2017 and fulfilled in January 2018. For the year ended December 31, 2016 we received redemption requests totaling approximately $1.3 million, (approximately 138,000 shares), approximately $1.1 million of which were fulfilled during the year ended December 31, 2016, with the remaining approximately $0.2 million included in accounts payable and accrued liabilities as of December 31, 2016 and fulfilled in January 2017.
Accounting for Equity Awards	Accounting for Equity Awards The cost of restricted stock is required to be measured based on the grant date fair value and the cost recognized over the relevant service period.
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 will 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. 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. 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, 2017 and 2016. 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, 2017 December 31, 2016 Fair Value Carrying Value Fair Value Carrying Value Fixed Rate Secured Debt $ 213,300,000 $ 218,332,483 $ 158,700,000 $ 166,410,537 As of December 31, 2017, we had interest rate swaps, an interest rate cap, and a net investment hedge (See Notes 5 and 6). 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 analysis reflected the contractual terms of the derivative, 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 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 will 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, 2017, 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. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. Amounts are reclassified out of other comprehensive income into earnings 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 necessarily equal net income as calculated in accordance with GAAP). As a REIT, we generally will not be subject to 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 federal income taxes on our taxable income at regular corporate rates and will not be permitted to qualify for treatment as a REIT for 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 federal income tax purposes. Even if we continue to qualify for taxation as a REIT, we may be subject to certain state and local taxes on our income and property, and federal income and excise taxes on our undistributed income. We filed elections to treat our TRS as a taxable REIT subsidiary effective January 1, 2014. In general, the TRS performs additional services for our customers and generally engages in any real estate or non-real estate related business. The TRS is subject to corporate federal and state income tax. The TRS follows accounting guidance which requires the use of the asset and liability method. Deferred income taxes represent the tax effect of future differences between the book and tax bases of assets and liabilities.
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 shares outstanding during the period, excluding unvested restricted stock. Diluted earnings per share is computed by including the dilutive effect of unvested restricted stock, utilizing the treasury stock method. For all periods presented, the dilutive effect of unrestricted stock was not included in the diluted weighted average shares as such shares were antidilutive.
Recently Issued Accounting Guidance	Recently Issued Accounting Guidance In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers” as ASC Topic 606. The objective of ASU 2014-09 is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most of the existing revenue recognition guidance, including industry-specific guidance. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying the new standard, companies will perform a five-step analysis of transactions to determine when and how revenue is recognized. ASU 2014-09 applies to all contracts with customers except those that are within the scope of other topics in the FASB ASC. In July 2015, the FASB voted to defer the effective date by one year to annual reporting periods (including interim periods within those periods) beginning after December 15, 2017 with early adoption permitted. This ASU will be applied using the modified retrospective approach. We have determined that our self storage rental revenues will not be subject to the guidance in ASU 2014-09, as they qualify as lease contracts, which are excluded from its scope. We adopted this ASU on January 1, 2018 and its adoption did not have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 amends the guidance on accounting for leases. Under ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short term leases) at the commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under ASU 2016-02, lessor accounting is largely unchanged. It also includes extensive amendments to the disclosure requirements. ASU 2016-02 is effective for fiscal years and interim periods beginning after December 15, 2018. Early adoption is permitted for financial statements that have not yet been made available for issuance. ASU 2016-02 requires a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. While we continue to evaluate the standard, based upon our assessment to date, we do not anticipate the adoption of this standard will have a material impact on our consolidated financial statements, because substantially all of our lease revenues are derived from month-to-month leases. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments.” ASU 2016-15 addresses eight classification issues related to the statement of cash flows. The guidance will become effective for periods beginning after December 15, 2017, with early adoption permitted. We adopted this ASU on January 1, 2018 and its adoption did not have a material impact on our consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash.” ASU 2016-18 will require companies to include restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 will require a disclosure of a reconciliation between the statement of financial position and the statement of cash flows when the statement of financial position includes more than one line item for cash, cash equivalents, restricted cash, and restricted cash equivalents. Entities with material restricted cash and restricted cash equivalent balances will be required to disclose the nature of the restrictions. ASU 2016-18 is effective for reporting periods beginning after December 15, 2017, with early adoption permitted, and will be applied retrospectively to all periods presented. We adopted this guidance on January 1, 2018 and will begin presenting restricted cash along with cash and cash equivalents in our consolidated statements of cash flows. In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business.” ASU 2017-01 clarifies the framework for determining whether an integrated set of assets and activities meets the definition of a business. The revised framework provides guidance for determining whether an integrated set of assets and activities is a business and narrows the definition of a business, which is expected to result in fewer transactions being accounted for as business combinations. Acquisitions of integrated sets of assets and activities that do not meet the definition of a business are accounted for as asset acquisitions. This update is effective for fiscal years and for interim periods within those fiscal years, beginning after December 15, 2017 and shall be applied on a prospective basis. We adopted this ASU on January 1, 2018. We expect that acquisitions of real estate or in-substance real estate will not meet the revised definition of a business because substantially all of the fair value is concentrated in a single identifiable asset or group of similar identifiable assets (i.e. land, buildings, and related intangible assets) or because the acquisition does 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, certain transaction costs will be capitalized rather than expensed.
