Organization	Note 1. Organization
	SmartStop Self Storage, Inc. (formerly known as Strategic Storage Trust, Inc.), a Maryland corporation (the “Company”), was formed on August 14, 2007 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” and “our” refer to SmartStop Self Storage, Inc.
	On September 4, 2014, we and our operating partnership, SmartStop Self Storage Operating Partnership, L.P. (formerly known as Strategic Storage Operating Partnership, L.P.) (the “Operating Partnership”), entered into a series of transactions, agreements, and amendments to our existing agreements and arrangements (such agreements and amendments hereinafter referred to collectively as the “Self Administration and Investment Management Transaction”), with Strategic Storage Holdings, LLC (“SSH”) and our former advisor, Strategic Storage Advisor, LLC (the “Former Advisor”), pursuant to which, effective as of August 31, 2014, we acquired the self storage advisory, asset management, property management and investment management businesses of SSH. SSH was the sole member of the Former Advisor and Strategic Storage Property Management, LLC (the “Property Manager”). The Former Advisor had been responsible for, among other things, managing our affairs on a day-to-day basis and identifying and making acquisitions and investments on our behalf. As a result of the Self Administration and Investment Management Transaction, we are now self-managed, succeed to the advisory, asset management and property management arrangements with two additional REITs, Strategic Storage Trust II, Inc. (“SST II”) and Strategic Storage Growth Trust, Inc. (“SSGT”) (collectively “the Managed REITs”), and now have the internal capability to originate, structure and manage additional investment products. See Note 3, Self Administration and Investment Management Transaction, for additional information.
	Strategic Capital Holdings, LLC, a Virginia limited liability company (our “Former Sponsor”), was our sponsor through August 31, 2014. Our Former Sponsor was formed on July 21, 2004 to engage in private structured offerings of limited partnerships and other entities with respect to the acquisition, management and disposition of commercial real estate assets. Our Former Sponsor owns a majority of SSH, which was the sole member of both our Former Advisor and our Property Manager. Our Former Advisor was 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 our former advisory agreement we had with our Former Advisor (our “Former Advisory Agreement”). Some of the officers of our Former Advisor were also officers of our Former Sponsor and of us.
	On August 24, 2007, our Former Advisor purchased 100 shares of our common stock for $1,000 and became our initial stockholder. Our Second Articles of Amendment and Restatement authorize 700,000,000 shares of common stock with a par value of $0.001 and 200,000,000 shares of preferred stock with a par value of $0.001.
	Our Operating Partnership, a Delaware limited partnership, was formed on August 14, 2007. On August 24, 2007, our Former Advisor purchased a limited partnership interest in our Operating Partnership for $200,000 and on August 24, 2007, we contributed the initial $1,000 capital contribution we received to our Operating Partnership in exchange for the general partner interest. Our Operating Partnership owns, directly or indirectly through one or more special purpose entities, all of the self storage properties that we have acquired. Inclusive of the Class B limited partnership interests, as of December 31, 2014, we owned 94.61% of the limited partnership interests of our Operating Partnership. The remaining limited partnership interests (inclusive of the Class B limited partnership interests) are owned by unaffiliated third parties (1.02%) and our Former Advisor and its affiliates (4.37%) and totaled 3,316,992 limited partnership units. As the sole general partner of our Operating Partnership, we have the exclusive power to manage and conduct business of our Operating Partnership. We will conduct certain activities (such as selling packing supplies and locks; advisory and property management services; and earn tenant insurance related revenue) through our taxable REIT subsidiaries (the “TRSs”), which are our wholly-owned subsidiaries.
	Through August 31, 2014, our Property Manager was Strategic Storage Property Management, LLC, a Delaware limited liability company, which was formed in August 2007 to manage our properties. SSH owned 100% of the Property Manager’s membership interests until we acquired such interests through the Self Administration and Investment Management Transaction.
	On March 17, 2008, we began our initial public offering of common stock (our “Initial Offering”). On May 22, 2008, we satisfied the minimum offering requirements of the Initial Offering and commenced formal operations. On September 16, 2011, we terminated the Initial Offering, having sold approximately 29 million shares for gross proceeds of approximately $289 million. On September 22, 2011, we commenced our follow-on public offering of stock for a maximum of 110,000,000 shares of common stock, consisting of 100,000,000 shares for sale to the public (our “Primary Offering”) and 10,000,000 shares for sale pursuant to our distribution reinvestment plan (collectively, our “Offering”). Our Offering terminated on September 22, 2013, having sold approximately 25 million shares of common stock for gross proceeds of approximately $256 million. On September 18, 2013, our board of directors amended and restated our distribution reinvestment plan, effective September 28, 2013, to make certain minor revisions related to the closing of our Offering. Following the termination of our Offering, on September 23, 2013, we filed with the SEC a Registration Statement on Form S-3, which incorporated the amended and restated distribution reinvestment plan and registered up to an additional $51.25 million in shares under our amended and restated 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, 2014, we had sold approximately 56 million shares of common stock for gross proceeds of approximately $568 million under all of our offerings.
	In connection with the close-down of our Offering and in light of current market conditions, our board of directors has been and is continuing to explore certain strategic alternatives designed to provide stockholder liquidity at some point in the future, including, but not limited to, a potential listing of our shares on a national securities exchange. Our board of directors recognized that certain potential liquidity events may be enhanced if we first became self-administered. For example, we believed that our shares may be valued higher by the market if we became self-administered and those individuals responsible for managing our affairs were our own employees rather than those of an external advisor. Also, we may be able to sell our Company for a higher price or attract institutional equity as a self-administered company if the purchaser desires our management team and employees, along with our assets. Therefore, effective August 31, 2014, we became self-administered by acquiring substantially all of the operating assets of SSH. See Note 3, Self Administration and Investment Management Transaction, for additional information. There can be no assurance that the exploration of any strategic alternatives will result in any particular outcome. In anticipation of potential strategic alternatives, on November 1, 2013, our board of directors approved the termination of our share redemption program, effective December 1, 2013.
	Our dealer manager was Select Capital Corporation, a California corporation (our “Dealer Manager”). Our Dealer Manager was responsible for marketing our shares that were offered pursuant to the Offering. Prior to the Self Administration and Investment Management Transaction, our Chief Executive Officer, through a wholly-owned limited liability company, owned a 15% non-voting equity interest in our Dealer Manager. We acquired that equity interest through the Self Administration and Investment Management Transaction.
	As we accepted subscriptions for shares of our common stock, we transferred substantially all of the net offering proceeds to our Operating Partnership as capital contributions in exchange for additional limited partnership units in our Operating Partnership. However, we were deemed to have made capital contributions in the amount of the gross offering 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 (except for Class D units) that will be equivalent to the distributions made to holders of our common stock. In March 2011, we adopted Amendment No. 1 to our Operating Partnership’s First Amended and Restated Limited Partnership Agreement, which established Class D Units, and our Operating Partnership issued approximately 120,000 Class D Units in connection with our acquisition of the Las Vegas VII and Las Vegas VIII properties. The Class D Units have all of the rights, powers, duties and preferences of our Operating Partnership’s other limited partnership units, except that they are subject to a distribution limit and the holders of the Class D Units have agreed to modified exchange rights that prevent them from exercising their exchange rights until the occurrence of a specified event (see Note 10). The distribution for the Class D units was initially zero, but was set to an annualized rate of $0.70 per unit as of April 1, 2014. 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 as outlined in the limited partnership agreement. Our Former Advisor was prohibited from exchanging or otherwise transferring its limited partnership units so long as it was acting as our Advisor pursuant to our Former Advisory Agreement.
	On September 4, 2014, we adopted the Third Amended and Restated Agreement of Limited Partnership of our Operating Partnership and issued Class B Limited Partnership Units (“Class B Units”) in connection with the Self Administration and Investment Management Transaction. See Note 3, Self Administration and Investment Management Transaction, for additional information.
	As of December 31, 2014, we owned 126 self storage facilities (125 were wholly owned and one was 99% owned by us) located in 17 states (Alabama, Arizona, California, Florida, Georgia, Illinois, Kentucky, Mississippi, Nevada, New Jersey, New York, North Carolina, Pennsylvania, South Carolina, Tennessee, Texas and Virginia) and Canada (the Greater Toronto Area). As of December 31, 2014, we also had noncontrolling interests in two additional self storage facilities.

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.
	Effective September 15, 2009, the ASC was established as the single source of authoritative nongovernmental GAAP. Prior to the issuance of the ASC, all GAAP pronouncements were issued in separate topical pronouncements in the form of statements, staff positions or Emerging Issues Task Force Abstracts, and were referred to as such. While the ASC does not change GAAP, it introduces a new structure and supersedes all previously issued non-SEC accounting and reporting standards. In addition to the ASC, the Company is still required to follow SEC rules and regulations relating to the preparation of financial statements. The Company’s accounting policies are consistent with the guidance set forth by both the ASC and the SEC.
	Reclassifications
	Certain amounts previously reported in our 2013 financial statements have been reclassified to conform to the fiscal 2014 presentation.
	Principles of Consolidation
	Our financial statements, the financial statements of our Operating Partnership, including its wholly-owned subsidiaries, the financial statements of Self Storage REIT, LLC (REIT I) and Self Storage REIT II, LLC (REIT II) are consolidated in the accompanying consolidated financial statements. The portion of these entities not wholly-owned by us is presented as noncontrolling interests both as of and during the periods presented. 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 (a “VIE”) and determining when a company should include the assets, liabilities, noncontrolling interests, and results of activities of the 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. As of December 31, 2014 and 2013, we had entered into contracts/interests that are deemed to be variable interests in VIEs; those variable interests include both lease agreements and equity investments. We have evaluated those variable interests against the criteria for consolidation and determined that we are not the primary beneficiary of certain investments discussed further in the “Equity Investments” section of this note.
	As of December 31, 2013, we had an equity interest in a self storage property located in San Francisco, California (“SF Property”) which was deemed to be a VIE of which we were the primary beneficiary. As such, the SF Property was consolidated in our consolidated financial statements since the date we first acquired our interest in the property through the REIT I merger. In January 2010, we acquired an approximately 2% additional interest in the SF Property, bringing our then total interest to approximately 12%. The SF Property is owned by a Delaware Statutory Trust (“DST”), and by virtue of the trust agreement the investors in the trust did not have the direct or indirect ability through voting rights to make decisions about the DST’s significant activities. The REIT I operating partnership (the “REIT I Operating Partnership”) had also entered into a lease agreement for the SF Property, in which the REIT I Operating Partnership was the tenant, which exposed it to losses of the VIE that could be significant to the VIE and also allowed it to direct activities of the VIE that determined its economic performance by means of its operation of the leased facility. In connection with the REIT I merger, our Former Sponsor entered into an agreement to indemnify us for any losses as a result of potential shortfalls in the lease payments required to be made by the REIT I Operating Partnership. Despite such indemnification, we were deemed to be the primary beneficiary, as our Former Sponsor was not deemed to have a variable interest in the SF Property.
	During January and February 2014, we acquired an additional approximately 86% of interests in the SF Property (through our acquisition of beneficial interests in the DST) from approximately 45 third-party sellers bringing our total interest to approximately 98%. During May 2014, we acquired an additional approximately 1% from one third-party seller, bringing our current ownership to approximately 99%. Given that we had consolidated the SF Property since we acquired the original interest, the acquisition of interests during 2014 were treated as acquisitions of noncontrolling interests and the SF Property has since been consolidated as a majority owned subsidiary whereas we previously consolidated it as a VIE. For additional discussion, see Note 4.
	Use of Estimates
	The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States 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 adjusts such estimates when facts and circumstances dictate. 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 of assets held by equity method investees, and the useful lives of real estate assets and intangibles. Actual results could materially differ from those estimates.
	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 equivalents in financial institutions in excess of insured limits, but believe this risk is 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.
	Purchase Price Allocation
	We account for acquisitions in accordance with accounting guidance 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 and to adjust those estimates as necessary during the measurement period (defined as the period, not to exceed one year, in which we may adjust the provisional amounts recognized for an acquisition). 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. Accordingly, to date we have not allocated any portion of the purchase price to above or below market leases. We also consider whether in-place, market leases represent an intangible asset. We recorded approximately $1.3 million and approximately $7.1 million in intangible assets to recognize the value of in-place leases related to our acquisitions in 2014 and 2013, respectively. We do not expect, nor to date have we recorded, intangible assets for the value of customer relationships because we will not have concentrations of significant customers and the average customer turnover is fairly frequent. Our acquisition-related transaction costs are required to be expensed as incurred. During the years ended December 31, 2014, 2013 and 2012 we expensed approximately $0.8 million, $2.4 million and $3.6 million, respectively, of acquisition related transaction costs.
	Should the initial accounting for an acquisition be incomplete by the end of a reporting period that falls within the measurement period, we report provisional amounts in our financial statements. During the measurement period, we adjust the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date and we record those adjustments to our financial statements. We apply those measurement period adjustments that we determine to be significant retrospectively to comparative information in our financial statements, potentially including adjustments to interest, depreciation and amortization expense.
	Evaluation of Possible Impairment of Long-Lived Assets
	Management will continually monitor events and changes in circumstances that could indicate that the carrying amounts of our long-lived assets, including those held through joint ventures, 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. As of December 31, 2014 and 2013, no impairment losses have been recognized.
	Goodwill Valuation
	We have recorded goodwill of approximately $12.7 million as a result of the Self Administration and Investment Management Transaction. Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible assets and other intangible assets acquired. Goodwill is allocated to various reporting units, as applicable and is not amortized. We will perform an annual impairment test for goodwill and between annual tests, we will evaluate the recoverability of goodwill whenever events or changes in circumstances indicate that the carrying amount of goodwill may not be fully recoverable. In our impairment tests of goodwill, we will first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If based on this assessment, management determines that the fair value of the reporting unit is not less than its carrying amount, then performing the additional two-step impairment test is unnecessary. If the carrying amount of goodwill exceeds its fair value, an impairment charge will be recognized.
	Trademarks
	Trademarks are based on the value of our brands. Trademarks are valued using the relief from royalty method, which presumes that without ownership of such trademarks, we would have to make a stream of payments to a brand or franchise owner in return for the right to use their name. By virtue of this asset, we avoid any such payments and record the related intangible value of our ownership of the brand name. We used the following significant projections and assumptions to determine value under the relief from royalty method: revenues; royalty rate; tax expense; terminal growth rate; and discount rate. For the SmartStop® trademark, the projections underlying this relief from royalty model were forecasted for eight years and then a terminal value calculation was applied. For the Strategic Storage® trademark, the projections underlying the relief from royalty model were forecasted for six years. Applying the selected pretax royalty rates to the applicable revenue base in each period yielded pretax income for each of our trademarks. These pretax totals were tax effected utilizing the applicable tax rate to arrive at net, after-tax cash flows. The net, after-tax flows were then discounted to present value utilizing an appropriate discount rate. The present value of the after-tax cash flows were then added to the present value of the amortization tax benefit (considering the 15-year amortization of intangible assets pursuant to U.S. tax legislation) to arrive at the recommended fair values for the trademarks.
	We will evaluate whether any triggering events or changes in circumstances have occurred subsequent to our annual impairment test that would indicate an impairment condition may exist. If any change in circumstance or triggering event occurs, and results in a significant impact to our revenue and profitability projections, or any significant assumption in our valuations methods is adversely impacted, the impact could result in a material impairment charge in the future.
	In connection with the Self Administration and Investment Management Transaction, we recorded $11.5 million associated with the two primary trademarks acquired. Prior thereto we had no amounts recorded related to trademarks.
	Approximately $10.9 million of the original $11.5 million of trademarks relates to the “SmartStop®” trademark, which is an indefinite-lived intangible. The remaining approximately $0.6 million relates to our “Strategic Storage®” trademark and will be amortized over a five year period. As of December 31, 2014 we had accumulated amortization of $40,000 associated with the “Strategic Storage®” trademark.
	The total estimated amortization expense of the “Strategic Storage®” trademark asset for the years ending December 31, 2015, 2016, 2017, 2018 and 2019 is approximately $120,000, $120,000, $120,000, $120,000, and $80,000, respectively.
	Equity Investments
	Our investments in unconsolidated real estate entities and VIEs in which we are not the primary beneficiary, where we have significant influence, but not control, are recorded under the equity method of accounting in the accompanying consolidated financial statements. Under the equity method, our investments in real estate entities are stated at cost and adjusted for our share of net earnings or losses and reduced by distributions. Equity in earnings of real estate entities are generally recognized based on the allocation of cash distributions upon liquidation of the investment in accordance with the joint venture agreements.
	Investments representing passive preferred equity and/or noncontrolling interests are accounted for under the cost method. Under the cost method, our investments in real estate ventures are carried at cost and adjusted for other-than-temporary declines in fair value, distributions representing a return of capital and additional investments.
	Through mergers with REIT I and REIT II in 2009, we acquired preferred equity and/or noncontrolling interests in unconsolidated real estate entities all of which were deemed to be VIEs. We currently have one such interest and have evaluated such interest against the amended criteria for consolidation and determined that we are not the primary beneficiary, generally due to our inability to direct significant activities that determine the economic performance of the VIE. The investment is a passive interest in two self storage facilities (such properties are owned by a DST, and by virtue of the related trust agreements, the investors have no direct or indirect ability through voting rights to make decisions about its significant activities) and is therefore accounted for under the cost method; our aggregate investment therein is approximately $0.1 million. Our ownership interest in such investment was approximately 1.49% and our risk of loss is limited to our investment therein.
	In May 2012, our equity interest in an unconsolidated joint venture which owned a self storage facility in Baltimore, Maryland was redeemed for approximately $1.4 million. This resulted in a gain of approximately $0.8 million, which is included in equity in earnings – gain related to property sale by unconsolidated entity in our Consolidated Statement of Operations for the year ended December 31, 2012.
	We own a 12% interest in Westport LAX LLC, a joint venture that originally acquired a net leased industrial property (the “Hawthorne Property”) in California. This investment is accounted for under the equity method. In July 2014 the Hawthorne Property was sold, and we received a distribution of approximately $3 million relative to our 12% ownership in Westport LAX LLC, resulting in a gain of approximately $1.9 million. The remaining carrying value of our investment therein is approximately $0.1 million.
	Hawthorne LLC, an affiliate of our Former Sponsor, owns 78% of Westport LAX LLC, and we had a preferred equity interest in Hawthorne LLC which entitled us to distributions equal to 10% per annum on our investment of approximately $6.9 million pursuant to terms of the preferred equity interest in Hawthorne LLC. In August 2014 we received our preferred investment in full along with the accumulated preferred return thereon in connection with the sale of the Hawthorne Property. The remaining 10% interest in Westport LAX LLC is owned by a third party, who was also the co-manager, along with our Former Sponsor, of the Hawthorne Property. Such third party has been and continues to be the acting manager and directed the operating activities of the property that determined its economic performance. We, along with other non-affiliated parties, were guarantors on the approximately $19 million loan that encumbered the Hawthorne Property until the property was sold in July 2014 and the loan was assumed by the buyer. As of December 31, 2014, we had no further exposure to loss as a result of our involvement with this VIE, other than our remaining investment balance of approximately $0.1 million.
	Investments in and Advances to Managed REITs
	As of December 31, 2014, we owned equity investments with a carrying value of approximately $0.4 million in the Managed REITs. We account for these investments using the equity method of accounting as we have the ability to exercise significant influence, but not control, over the Managed REITs’ operating and financial policies through our advisory and property management agreements with the respective Managed REITs. The equity method of accounting requires the investment to be initially recoded at cost and subsequently adjusted for our share of equity in the respective Managed REIT’s earnings and reduced by distributions.
	Also included in investments in and advances to managed REITs are receivables from the Managed REITs of approximately $1.8 million and our investment in the preferred units in the Managed REITs, totaling approximately $16.8 million. For additional discussion, see Note 8.
	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 rents contractually due but unpaid are included in other assets.
	Investment management revenue includes advisory, asset management, property management and other similar fees. Such fees are earned pursuant to the advisory and property management agreements with the Managed REITs. The fees are recognized in the periods during which the related services are performed and the amounts have been contractually earned.
	Allowance for Doubtful Accounts
	Tenant accounts receivable are 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 at cost. 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 as follows:
	Description		Standard Depreciable Life
	Land			Not Depreciated
	Buildings			30 to 35 years
	Site Improvements			7 to 15 years
	Depreciation of Personal Property Assets
	Personal property assets, consisting primarily of furniture, fixtures and equipment 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 allocate a portion of the real estate purchase price of a property to in-place leases. We are amortizing in-place leases on a straight-line basis over the estimated future benefit period. As of December 31, 2014 and 2013, accumulated amortization of in-place lease intangibles totaled approximately $50.5 million and $44.6 million, respectively.
	The total estimated amortization expense of such intangible assets for the years ending December 31, 2015, 2016, 2017, 2018 and 2019 is approximately $3.8 million, $2.0 million, $0.2 million, none and none, respectively.
	In connection with the Self Administration and Investment Management Transaction, we allocated a portion of the consideration to the contracts that we acquired to manage the Managed REITs. We are amortizing certain amounts on a straight-line basis over the estimated benefit period of those contracts. As of December 31, 2014, the gross amount allocated to the contracts was $5.3 million and the accumulated amortization was approximately $0.2 million. The total estimated amortization expense for such intangible assets for the years ending December 31, 2015, 2016, 2017, 2018 and 2019 is approximately $0.5 million, $0.5 million, $0.5 million, $0.5 million, and $0.3 million, respectively. Approximately $2.7 million of value related to the management contracts was derived from cash flows we expect to be collected and subsequently paid to SSH, pursuant to the Acquisition Fee Tail Agreement. Such cash flows, if received, will reduce the carrying value of the management contracts. As of December 31, 2014, approximately $0.4 million of such cash flows were received by us and reduced the carrying value of the contracts, but were not paid to SSH as the payout ratio (as defined) had not been achieved (See Note 3 for additional information).
	Amortization of Deferred Financing Costs
	Costs incurred in connection with obtaining financing are deferred and 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, 2014 and 2013, accumulated amortization of deferred financing costs totaled approximately $7.3 million and $5.9 million, respectively.
Organization and Offering Costs
Pursuant to our Former Advisory Agreement, our Former Advisor funded organization and offering costs on our behalf. We were required to reimburse our Former Advisor for such organization and offering costs; provided, however, our Former 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 and dealer manager fees) in excess of 3.5% of the gross offering proceeds from the Primary Offering. Such costs were recognized as a liability when we had a present responsibility to reimburse our Former Advisor, which was defined in our Former Advisory Agreement as the date we satisfied the minimum offering requirements of the primary offering portion of our Initial Offering (which occurred on May 22, 2008). If we had determined that the total organization and offering costs had exceeded 3.5% of the gross proceeds to be received from the Primary Offering, we would have recognized such excess as a capital contribution from our Former Advisor. Subsequent to the termination of our Offering on September 22, 2013, we have determined that organization and offering costs did not exceed 3.5% of the gross proceeds from the Primary Offering. Offering costs are recorded as an offset to additional paid-in capital, and organization costs are recorded as an expense.
Redeemable Common Stock
We previously had a share redemption program that enabled stockholders to sell their shares to us in limited circumstances.
We recorded amounts that were redeemable under the share redemption program as redeemable common stock in the accompanying consolidated balance sheets since the shares were mandatorily redeemable at the option of the holder and therefore their redemption was outside our control. The maximum amount redeemable under our share redemption program was limited to the number of shares we could 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 but that are contingent on an event that is likely to occur (e.g., the passage of time) should be presented as redeemable when such amount is known. Therefore, the net proceeds from the distribution reinvestment plan were considered to be temporary equity and were presented as redeemable common stock in the accompanying consolidated balance sheets accordingly.
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 were contingently redeemable at the option of the holder. When we determined we had a mandatory obligation to repurchase shares under the share redemption program, we reclassified such obligations from temporary equity to a liability based upon their respective settlement values.
We funded all redemptions using proceeds from the sale of shares pursuant to our distribution reinvestment plan.
In anticipation of a future possible liquidity event, on November 1, 2013, our board of directors approved the termination of our share redemption program, effective December 1, 2013.
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). For the years ended December 31, 2014, 2013 and 2012, we recorded a loss of approximately $1,065,000, a loss of approximately $460,000, and a gain of approximately $60,000, respectively.
Accounting for Equity Awards
The cost of restricted stock is required to be measured based on the grant-date fair value and the cost to be recognized over the relevant service period.
Fair Value Measurements
The accounting standard for fair value measurements and disclosures defines fair value, establishes a framework for measuring fair value, and provides for expanded disclosure about fair value measurements. Fair value is defined by the accounting standard for fair value measurements and disclosures as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. It also establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels. The following summarizes the three levels of inputs and hierarchy of fair value we use when measuring fair value:
	•		Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access;
	•		Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as interest rates and yield curves that are observable at commonly quoted intervals; and
	•		Level 3 inputs are unobservable inputs for the assets or liabilities that are typically based on an entity’s own assumptions as there is little, if any, related market activity.
In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the fair value measurement will fall within the lowest level that is significant to the fair value measurement in its entirety.
The accounting guidance for fair value measurements and disclosures provides a framework for measuring fair value and establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. In determining fair value, we 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 is 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 present herein are 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 assets and investments in unconsolidated joint ventures and related liabilities assumed and equity consideration related to our acquisitions. The fair values of these assets, liabilities and equity consideration 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, liabilities and equity consideration as of the acquisition dates were derived using Level 3 inputs.
The carrying amounts of cash and cash equivalents, customer accounts receivable, other assets, accounts payable and accrued liabilities, distributions payable and amounts due to affiliates approximate fair value because of the relatively short-term nature of these instruments.
The table below summarizes our fixed rate notes payable at December 31, 2014 and 2013. 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, which amounts were derived using Level 3 inputs. Accordingly, the estimates presented below are not necessarily indicative of the amounts we would realize in a current market exchange.
		December 31, 2014				December 31, 2013
		Fair Value		Carrying Value		Fair Value		Carrying Value
Fixed Rate Secured Debt		$	303,295,393	$	287,655,570	$	311,362,132	$	300,894,201
Through December 24, 2014, we had an interest rate swap on one of our loans (See Notes 6 and 7). The valuation of this instrument was 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 derivatives, including the period to maturity, and used observable market-based inputs, including interest rate curves and implied volatilities. The fair values of interest rate swaps were determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts were based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. To comply with GAAP, we incorporated 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 our derivative contracts for the effect of nonperformance risk, we considered 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 24, 2014, we had assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and had determined that the credit valuation adjustments were not significant to the overall valuation of our derivatives. As a result, we had determined that our derivative valuations in their entirety were classified in Level 2 of the fair value hierarchy. As of December 31, 2013, through December 24, 2014, we had Level 2 derivatives (interest rate swap) classified in accounts payable and accrued liabilities on our consolidated balance sheet.
Derivative Instruments and Hedging Activities
The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected future cash flows or other types of forecasted transactions are considered cash flow hedges.
For derivatives designated as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in the consolidated statements of operations. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income, outside of earnings and subsequently reclassified to earnings when the hedged transaction affects earnings.
Noncontrolling Interest in Consolidated Entities
We account for the noncontrolling interest in our Operating Partnership in accordance with amended accounting guidance. Due to our control through our general partnership interest in our Operating Partnership and the limited rights of the limited partners, our Operating Partnership, including its wholly-owned subsidiaries, is consolidated with the Company and the limited partner interest is reflected as a noncontrolling interest in the accompanying consolidated balance sheets. In addition, we account for the noncontrolling interest in the SF Property and the SSGT and SST II advisor entities in accordance with the amended accounting guidance. The noncontrolling interests shall continue to be attributed their share of income and losses, even if that attribution results in a deficit noncontrolling interest balance.
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, 2008. To qualify as a REIT, we must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of the REIT’s ordinary taxable income to stockholders. 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 will be 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. We have concluded that there are no significant uncertain tax positions requiring recognition or disclosure in our consolidated financial statements.
Even if we 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 have filed an election to treat the TRSs as taxable REIT subsidiaries. In general, the TRSs may perform additional services for our customers and generally may engage in any real estate or non-real estate related business. The TRSs are subject to corporate federal and state income tax. The TRSs follow accounting guidance which requires the use of the asset and liability method. Deferred income taxes will 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 SmartStop Self Storage, Inc. for all periods presented are computed by dividing net income (loss) attributable to SmartStop Self Storage, Inc. by the weighted average number of shares outstanding during the period, excluding unvested restricted stock. Diluted earnings per share are computed by dividing net income (loss) attributable to SmartStop Self Storage, Inc. by the weighted average number of shares outstanding, adjusted for the dilutive effect of unvested restricted stock, utilizing the treasury stock method. For both of the years ended December 31, 2013 and 2012, 6,250 shares of unvested restricted stock were not included in the diluted weighted average shares calculation, as such shares were antidilutive.
Recently Issued Accounting Guidance
In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09 “Revenue from Contracts with Customers” (“ASU 2014-09”) as Accounting Standards Codification (“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. This ASU is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2016 and shall be applied using either a full retrospective or modified retrospective approach. Early adoption is not permitted. We are in the process of evaluating the impact of this standard on our consolidated financial statements and the impact is unknown at this time.
In April 2014, the FASB issued ASU No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of an Entity”. Under the new guidance, only disposals representing a strategic shift, such as a major line of business, a major geographical area or a major equity investment, should be presented as discontinued operations. The guidance will be applied prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. The guidance is effective for annual financial statements with fiscal years beginning on or after December 15, 2014 with early adoption permitted for disposals or classifications as held for sale which have not been reported in financial statements previously issued or available for issuance. We will adopt the guidance effective January 1, 2015. We are in the process of evaluating the impact of this standard on our consolidated financial statements and the impact is unknown at this time.
In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” ASU 2014-15 requires management to evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern, and to provide certain disclosures when it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued. ASU 2014-15 is effective for the annual period ended December 31, 2016 and for annual periods and interim periods thereafter with early adoption permitted. We are in the process of evaluating the impact of this standard on our consolidated financial statements and the impact is unknown at this time.
In February 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis.” ASU 2015-02 changes the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. Specifically, ASU 2015-02 modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities, eliminates the presumption that a general partner should consolidate a limited partnership, and affects the evaluation of fee arrangements in the primary beneficiary determination. ASU 2015-02 is effective for periods beginning after December 15, 2015 and early adoption is permitted. We are in the process of evaluating the impact of this standard on our consolidated financial statements and the impact is unknown at this time.

Self Administration and Investment Management Transaction	12 Months Ended
	Dec. 31, 2014
Text Block [Abstract]
Self Administration and Investment Management Transaction	Note 3. Self Administration and Investment Management Transaction
	Overview
	On September 4, 2014, we and our Operating Partnership entered into a series of transactions, agreements, and amendments to our existing agreements and arrangements (such agreements and amendments hereinafter referred to collectively as the “Self Administration and Investment Management Transaction”), with SSH and our Former Advisor, pursuant to which, effective as of August 31, 2014, we acquired the self storage advisory, asset management, property management and investment management businesses of SSH. SSH was the sole member of the Former Advisor and Property Manager. The Former Advisor had been responsible for, among other things, managing our affairs on a day-to-day basis and identifying and making acquisitions and investments on our behalf. As a result of the Self Administration and Investment Management Transaction, we are now self-managed, succeed to the advisory, asset management and property management arrangements with two additional REITs, SST II and SSGT, and we now have the internal capability to originate, structure and manage additional investment products. The Self Administration and Investment Management Transaction and the other transactions discussed herein were approved by our board of directors at the recommendation of a special committee of the board of directors comprised solely of independent directors.
	SSH Contribution Agreement
	On September 4, 2014, we along with the Operating Partnership, as Contributee, and SSH, as Contributor, entered into a Contribution Agreement (the “SSH Contribution Agreement”) whereby, effective August 31, 2014, the Operating Partnership acquired substantially all of SSH’s operating assets, including (a) SSH’s 100% membership interests in (i) the Property Manager, (ii) Strategic Storage Opportunities, LLC, (iii) Strategic Storage Realty Group, LLC, the parent company of the advisors and property managers for SST II and SSGT, respectively, and (iv) Strategic Capital Markets Group, LLC, which owns a 15% non-voting equity interest in Select Capital Corporation, our former dealer manager and the current dealer manager for SST II and SSGT, (b) all equipment, furnishings, fixtures, computer equipment and certain other personal property as set forth in the SSH Contribution Agreement, (c) all intellectual property, goodwill, licenses and sublicenses granted and obtained with respect thereto (including all rights to the “SmartStop®” brand and “Strategic Storage®” related trademarks), (d) all of SSH’s Software as defined in the SSH Contribution Agreement, (e) all of SSH’s processes, practices, procedures and workforce (including a fully integrated operations team of approximately 300 self storage and other professionals), and (f) certain other assets as set forth in the SSH Contribution Agreement, in exchange for $18 million in cash and 773,395 units of limited partnership in the Operating Partnership (“OP Units”).
	The SSH Contribution Agreement contains customary representations, warranties, covenants and agreements of us, the Operating Partnership and SSH.
	Termination of Advisor Agreements and Contribution of Special Limited Partnership Interests
	On September 4, 2014, we along with the Operating Partnership entered into a Termination of Advisory Agreement (the “Advisory Agreement Termination”) with the Former Advisor. Pursuant to the Advisory Agreement Termination, the advisory agreement between us, the Operating Partnership, and our Former Advisor was terminated, effective August 31, 2014, and is of no further force and effect.
	In addition, Self Storage REIT, LLC, a wholly-owned subsidiary of the Operating Partnership (“REIT I”), entered into a Termination of Advisory Agreement (the “REIT I Advisory Agreement Termination”) with USA Self Storage Advisor LLC, the advisor to REIT I (“REIT I Advisor”), and Self Storage REIT II, LLC, a wholly-owned subsidiary of the Operating Partnership (“REIT II”), entered into a Termination of Advisory Agreement (the “REIT II Advisory Agreement Termination”) with SS REIT II Advisor, LLC, the advisor to REIT II (“REIT II Advisor”), resulting in the termination of the respective advisory agreements of REIT I and REIT II.
	On September 4, 2014, pursuant to a limited partner interest contribution agreement (the “Limited Partner Interest Contribution Agreement”), by and among the Operating Partnership, USA Self Storage Operating Partnership, LP (“REIT I Operating Partnership”), USA SS REIT II Operating Partnership, L.P. (“REIT II Operating Partnership”), the Former Advisor, REIT I Advisor and REIT II Advisor, (1) the Former Advisor contributed its special limited partner interest in the Operating Partnership to the Operating Partnership in exchange for 659,696 OP Units and 691,876 Class B Limited Partnership Units of the Operating Partnership (“Class B Units”), (2) REIT I Advisor contributed both its special limited partner interest in the Operating Partnership and its Class B limited partnership units in REIT I Operating Partnership to the Operating Partnership in exchange for 102,846 OP Units and 107,863 Class B Units, and (3) REIT II Advisor contributed both its special limited partner interest in the Operating Partnership and its Class B limited partnership units in REIT II Operating Partnership to the Operating Partnership in exchange for 30,188 OP Units and 31,660 Class B Units.
	As a result of the Limited Partner Interest Contribution Agreement, the Former Advisor, REIT I Advisor, and REIT II Advisor no longer have a special limited partner interest in the Operating Partnership, REIT I Operating Partnership or REIT II Operating Partnership; however, the Former Advisor, REIT I Advisor and REIT II Advisor will now hold OP Units and Class B Units in the Operating Partnership. See “Amendments to Operating Partnership Agreements” below. The Class B Units shall have the following rights, preferences and limitations:
		•		The Class B Units shall be converted on a per unit basis into OP Units at the later of (i) two years from the date of issuance, or (ii) the date on which the OP Units have a fully diluted estimated net asset value per unit (after giving effect to the conversion of the Class B Units) exceeding $10.81, calculated in accordance with the provisions of Practice Guideline 2013-01, Valuations of Publicly Registered Non-Listed REITs, issued by the Investment Program Association (IPA) in April 2013 (the “IPA Guidelines”); provided, however, that the estimated net asset value per unit shall take into account the value of the assets acquired by the Operating Partnership, pursuant to the SSH Contribution Agreement and the Churchill Contribution Agreement (as defined below);
		•		The Class B Units shall be automatically converted into OP Units in the event of a change in control or listing event (with market value in a listing measured by the average closing price during a 30-day period commencing at any time between 180 days and 540 days following listing) at a price in excess of $10.81 per share;
		•		The Class B Units shall only be converted to the extent that, after giving effect to such conversion, the value of a share in the event of a change in control or listing event is greater than $10.81;
		•		The Class B Units shall have no distribution rights and, hence, will receive no distributions prior to their conversion to OP Units; and
		•		The Class B Units shall have no voting rights, except for approval rights for any amendments to the rights and obligations of the Class B Units.
	The Limited Partner Interest Contribution Agreement contained various customary representations and warranties.
	Amendments to Operating Partnership Agreements
	On September 4, 2014, we entered into a Third Amended and Restated Agreement of Limited Partnership of the Operating Partnership (the “Operating Partnership Agreement”), which amends and supersedes the Second Amended and Restated Limited Partnership Agreement (the “Former OP Agreement”). In addition, REIT I entered into Amendment No. 2 to the Agreement of Limited Partnership of REIT I Operating Partnership (the “REIT I OP Agreement Amendment”), and REIT II entered into Amendment No. 2 to the Agreement of Limited Partnership of REIT II Operating Partnership (the “REIT II OP Agreement Amendment”).
	As a result of the entry into the above-described Limited Partner Interest Contribution Agreement and the Operating Partnership Agreement, the REIT I OP Agreement Amendment, and the REIT II OP Agreement Amendment, (1) references to the special limited partner interests previously held by the Former Advisor, REIT I Advisor, and REIT II Advisor in each of the respective operating partnerships have been removed from the respective agreements, in connection with the exchange of such interests pursuant to the Limited Partner Interest Contribution Agreement, and (2) provisions related to the subordinated incentive distributions payable to the special limited partners pursuant to the special limited partnership interests have been removed from the respective agreements. Accordingly, we and the Operating Partnership will no longer have any obligation to make the distributions of Net Sale Proceeds, Subordinated Incentive Listing Distribution, Subordinated Distribution Due Upon Extraordinary Transaction or Subordinated Distribution Due Upon Termination (each as defined in the Former OP Agreement).
	Agreement Regarding Acquisition Fees
	We, the Operating Partnership and SSH agreed that for a period of six months following the closing of the Self Administration and Investment Management Transaction, subject to certain extensions, SSH, as the parent company of the Former Advisor and former ultimate parent company of Strategic Storage Advisor II, LLC, the advisor to SST II, and SS Growth Advisor, LLC, the advisor to SSGT, will retain any and all acquisition fees that would have been due under their respective advisory agreements (“Acquisition Fee Tail Agreement”) with respect to any properties whose acquisition was pending, under contract, or was otherwise in process as of the closing of the Self Administration and Investment Management Transaction. The parties agreed that the first $2.0 million in such acquisition fees otherwise payable will be deferred until the payout ratio (as defined in the agreement and calculated to include the payment of any portion of the deferred fees that SSH is entitled to be paid) is 100% or less for any quarterly period.
	Fair Value of Consideration Transferred
	We accounted for the SSH Contribution Agreement discussed above as a business combination under the acquisition method of accounting. During the years ended December 31, 2014 and 2013, we incurred approximately $2.1 million and $0.5 million, respectively, for legal fees and fees and expenses of our other professional and financial advisors related to the Self Administration and Investment Management Transaction, which are included in the self administration and investment management transaction expenses line-item in the accompanying consolidated statements of operations.
	We are in the process of gathering certain additional information in order to finalize our assessment of the fair value of the consideration transferred; thus, the fair values are subject to change. The estimated fair value of the consideration transferred totaled $29.1 million and consisted of the following:
	Estimated Fair Value of		September 4, 2014
	Consideration Transferred:
	Cash(1)		$	17,797,486
	OP Units			8,632,000
	Contingent consideration - acquisition fee tail			2,690,000
	Total consideration transferred		$	29,119,486
	(1)	The SSH Contribution Agreement called for a true-up related to the assumption of certain operating assets and liabilities. We assumed a net liability of approximately $0.2 million and such amount was netted against the cash payment otherwise due to SSH.
	The estimated fair value of the Company’s OP Units issued was determined using an income approach to value the property and advisory businesses and management’s estimates of the Company’s net asset value, adjusted for market related adjustments and illiquidity discounts.
	These fair value measurements are based on significant inputs not observable in the market and thus represent a Level 3 measurement as discussed in Note 2. The key assumptions used in estimating the fair value of the OP Unit consideration included (i) an aggregate combined minority and marketability discount of 10%, (ii) a capitalization rate of 5.5% and (iii) annual net operating income of approximately $61 million.
	Allocation of Consideration
	The consideration transferred pursuant to the SSH Contribution Agreement was allocated to the assets acquired and liabilities assumed, based upon their preliminary estimated fair values as of the acquisition date. The Company is in the process of gathering certain additional information in order to finalize its assessment of the fair value of certain intangible assets; thus, the provisional measurements of trademarks, management contracts and goodwill are subject to change. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed:
			September 4, 2014
	Identifiable Assets Acquired at Fair Value
	Cash and cash equivalents		$	90,351
	Property and equipment			157,000
	Investments in and advances to managed REITs			403,000
	Other assets			87,835
	Trademarks			11,500,000
	Management contracts			5,290,000
	Total identifiable assets acquired		$	17,528,186
	Identifiable Liabilities Assumed at Fair Value
	Accounts payable and accrued expenses		$	783,700
	Deferred tax liabilities, net			330,000
	Total liabilities assumed			1,113,700
	Net identifiable assets acquired			16,414,486
	Goodwill			12,705,000
	Net assets acquired		$	29,119,486
	The intangible assets acquired primarily consist of trademarks and the management and advisory contracts that we have with the Managed REITs.
	The value of the management and advisory contracts were determined based on a discounted cash flow valuation of the projected revenues of the acquired contracts.
	The deferred tax liability is the result of differences between the GAAP carrying value of certain assets and the carrying value for tax purposes related to activities which are conducted through our TRS.
	The goodwill recognized is supported by several factors of the Company as a combined entity, including that the Company is one of the largest self storage REITs and the investment management business brings an established management platform with numerous strategic benefits including growth from new income streams and the ability to offer new products. We have not yet completed our allocation of goodwill to the respective reporting units.
	The results of the acquisition have been included in our consolidated statements of operations since the effective date of the transaction. For the period from the effective date of the acquisition to December 31, 2014, we recorded investment management revenues of approximately $0.2 million, avoided approximately $4.1 million of asset and property management fees and recorded additional expenses including - additional property operating expenses of approximately $0.5 million, approximately $0.7 million in investment management expenses, approximately $1.7 million of incremental general and administrative expenses and approximately $0.2 million of intangible amortization expense.
	Fair Value of Equity Exchanged Related to the Contribution of Special Limited Partnership Interests
	In connection with the Limited Partner Interest Contribution Agreement, the Former Advisor, REIT I Advisor, and REIT II Advisor contributed their special limited partnership interests and 20,000 OP Units in exchange for OP Units and Class B Units. The exchange was accounted for as a transaction among equity holders with no gain or loss recognized. The fair value of the special limited partnership interests contributed was approximately $16.9 million, while the book value of the OP Units and Class B Units issued that were recorded in noncontrolling interest was approximately $7.9 million. The difference between the fair value of the special limited partnership interest received and the book value of the OP Units and Class B Units issued was recorded to additional paid in capital.
	The estimated fair values of the Company’s OP Units and Class B Units issued were determined using an income approach to value the property and advisory businesses and management’s estimates of the Company’s net asset value, adjusted for market related adjustments and illiquidity discounts.
	These fair value measurements are based on significant inputs not observable in the market and thus represent a Level 3 measurement as discussed in Note 2. The key assumptions used in estimating the fair value of the OP Unit consideration and Class B Unit consideration, as applicable, included (i) a discount rate of 14%, (ii) an aggregate combined minority and marketability discount of 10%, (iii) capitalization rates ranging from 5.5% to 6.0% and (iv) annual net operating income ranging from approximately $61 million to $68 million.
	Acquisition of Interest in Reinsurance Company
	On September 4, 2014, we along with the Operating Partnership, as Contributee, and Churchill TRI, LLC (“Churchill”), an affiliate of our Chief Executive Officer and President, as Contributor, entered into a Contribution Agreement (the “Churchill Contribution Agreement”) whereby the Operating Partnership acquired Churchill’s ownership interest (approximately 5%) in SBOA TI Reinsurance Ltd. (the “Reinsurance Company”), a Cayman Islands exempted company, which reinsures a portion of the insurance required by the program insurer of the tenant insurance program, whereby tenants of our self storage facilities and tenants of other operators participating in the program can purchase insurance to cover damage or destruction to their personal property while stored at such facilities. In addition to the tenant insurance revenues we already receive directly from the program insurer, we will now be entitled to receive our share of distributions of any profits generated by the Reinsurance Company depending on actual losses incurred by the program. Churchill contributed its interest in the Reinsurance Company in exchange for approximately $4.1 million in cash and 290,023 OP Units.
	The Churchill Contribution Agreement contains customary representations, warranties, covenants and agreements of us, the Operating Partnership and Churchill.
The fair value of the total consideration of the interest in the Reinsurance Company has been preliminarily determined to be approximately $7.3 million, which consisted of approximately $4.1 million in cash and approximately $3.2 million in OP Units.

Under the Registration Rights Agreement, we agreed to file, no later than six months following the date upon which our common stock becomes available for trading pursuant to the initial listing of such common stock on a national securities exchange, as such term is defined under the Exchange Act, and use commercially reasonable efforts to cause to become effective as soon as practicable thereafter, a registration statement for the offering on a continuous or delayed basis in the future covering resales of shares of our common stock that may be acquired by SSH, Churchill, the Former Advisor, REIT I Advisor or REIT II Advisor in connection with the exercise by them of the exchange rights associated with the OP Units or Class B Units.
Pursuant to the terms of the SSH Contribution Agreement, Churchill Contribution Agreement and Limited Partner Interest Contribution Agreement, none of SSH, Churchill, the Former Advisor, the REIT I Advisor or the REIT II Advisor may transfer for a period of two years any of (a) the OP Units or Class B Units it receives pursuant to the SSH Contribution Agreement, Churchill Contribution Agreement or the Limited Partner Interest Contribution Agreement, as applicable, or (b) any shares of our common stock held by any of them upon exchange of the OP Units or Class B Units pursuant to the provisions of the Operating Partnership Agreement, except for certain permitted transfers, and, upon a change in control, such restrictions on transfer shall terminate.

The Contributors are not required to provide indemnification under the contribution agreements until aggregate losses incurred by us exceed $140,000, and then only to the extent of such losses over $140,000, but the maximum amount the Contributors are required to pay us for losses pursuant to such indemnification obligations is $2.1 million. We agreed to indemnify the Contributors for losses incurred by the Contributors arising from or relating to (i) a breach of any representation, warranty, covenant or agreement made by us in any of the contribution agreements or other Self Administration and Investment Management Transaction documents; (ii) the ownership or operation of the contributed assets after the closing of the Self Administration and Investment Management Transaction; and (iii) the assumed liabilities.

The level of severance pay depends upon the circumstances of the executive officer’s termination of employment. If the executive officer violates any of the restrictive covenants set forth in the Executive Officer Severance Agreements, that executive officer’s right to receive severance payments pursuant to the Executive Officer Severance Agreements will end immediately.

Business Combinations [Abstract]
Southwest Colonial, DST and USA SF Self Storage, DST Acquisitions	Note 4. Southwest Colonial, DST and USA SF Self Storage, DST Acquisitions
	Southwest Colonial, DST
	During the fourth quarter of 2013, we purchased beneficial interests (the “Colonial Interests”) in Southwest Colonial, DST (“Colonial DST”), a Delaware statutory trust sponsored by our Former Sponsor, from approximately 50 third-party sellers pursuant to separate purchase agreements with each seller. None of the purchases were contingent upon any of the others. Such purchases were fully completed on November 1, 2013. Following the purchase of these interests, we owned 100% of the interests in Colonial DST. The agreed upon purchase price of the Colonial Interests acquired, based on the aggregate appraised value of the five properties owned by Colonial DST was approximately $27.9 million. Consideration provided consisted of approximately $9.0 million in cash along with the issuance of approximately 151,300 limited partnership units in our Operating Partnership and the assumption of an approximately $16.7 million bank loan held by Colonial DST (the “John Hancock Loan”). Colonial DST leased its properties to a master tenant (the “Colonial Tenant”) on a triple-net basis pursuant to a master lease (the “Colonial Lease”). The Colonial Tenant is owned by affiliates of our Former Sponsor. We and our Former Sponsor, along with its affiliates, have agreed to assign 100% of the economic benefits and obligations from these properties to us in exchange for indemnification by us for any potential liability incurred subsequent to the assignment by the Former Sponsor in connection with the Colonial Lease.
	We incurred acquisition fees due to our Former Advisor of approximately $340,000 in connection with these acquisitions.
	Colonial DST owns five self storage facilities located in Texas with an aggregate of approximately 2,805 units and 392,000 rentable square feet. The properties owned by Colonial DST are subject to the John Hancock Loan, which had an aggregate principal balance of approximately $16.7 million as of the acquisition date. The loan bears a fixed interest rate of 6.36% and had an original term of ten years, maturing in June 2018. The loan is secured only by the five properties owned by Colonial DST that obtained such loan.
	USA SF Self Storage, DST
	During January and February 2014, through an indirect wholly-owned subsidiary, we closed on the purchase of an additional approximately 86% in beneficial interests (the “SF Interests”) in USA SF Self Storage, DST (the “SF DST”), a Delaware Statutory Trust sponsored by our Former Sponsor, from approximately 45 third-party sellers pursuant to separate purchase agreements with each seller. None of the purchases were contingent upon any of the others. The agreed upon purchase price of the property relating to the SF Interests acquired was approximately $20 million.
	The acquisition brought our ownership of the SF DST to approximately 98%, including approximately 12% that we acquired previously in unrelated transactions (See Note 2). The consideration provided was primarily in the form of approximately $5.7 million in cash, an assumption of the pro rata debt of approximately $10.2 million and the issuance of approximately 245,000 limited partnership units in our Operating Partnership. We paid our Former Advisor approximately $0.2 million in acquisition fees in connection with these acquisitions.
	During May 2014, we acquired an additional approximately 1% in beneficial interests from one third-party seller, bringing our current ownership to approximately 99%. Given that we had consolidated the SF Property since we acquired the original interest, the acquisition of interests during 2014 were treated as acquisitions of noncontrolling interests and the SF Property is now consolidated as a majority owned subsidiary whereas we previously consolidated it as a VIE.
	SF DST leases its property to a master tenant (the “REIT I Tenant”) on a triple-net basis pursuant to a master lease (the “San Francisco Lease”) that had an original term of ten years and will expire on December 19, 2016. The REIT I Tenant is a wholly-owned subsidiary of us. Under the San Francisco Lease, the REIT I Tenant is required to pay a stated monthly rent equivalent to the monthly debt service payment under the loan, which is paid directly to the lender on behalf of the SF DST, a monthly stated rent, and certain annual bonus rent per the terms of the San Francisco Lease. As a SF DST interest holder, we are entitled to our pro rata share of the total rent less the debt service under the loan.
	As of December 31, 2014, the SF DST had net real estate assets of approximately $16.3 million, approximately $10 million of secured debt and there was approximately $0.1 million of noncontrolling interest related to this entity. Such assets are only available to satisfy the obligations of the SF DST. The lenders of the secured debt have no recourse to other Company assets.

KeyBank Revolver
On October 28, 2013, through our Operating Partnership and certain property-owning special purpose entities wholly-owned by our Operating Partnership (collectively with the Operating Partnership, the “Borrower”), we obtained a revolving loan from KeyBank, National Association (“KeyBank”) for borrowings up to $75 million (as amended, the “KeyBank Revolver”). The initial amount funded at closing was $71 million (the “Initial Draw”), $45 million of which was used to pay off the outstanding principal amount under the Second Restated KeyBank Loan (discussed below), and thereby release the 12 properties comprising the Homeland Portfolio that were serving as collateral for the Second Restated KeyBank Loan , and approximately $26 million of which was used to partially fund the acquisition of three properties in Knoxville, Tennessee and one in Montgomery, Alabama (the “Knoxville Portfolio”). During the first quarter of 2014 the aggregate commitment under the KeyBank Revolver was increased from $75 million to $100 million. In addition, there are now four participating lenders, including KeyBank.
On April 28, 2014, we borrowed an additional $18 million on the KeyBank Revolver, bringing the total outstanding amount to $89 million. In addition to those properties encumbered as of December 31, 2013, we added as encumbered properties Riverdale, Hampton II, Chandler and SF Bay Area -Vallejo. The proceeds of the borrowings were used to repay the previously outstanding mortgage of approximately $4.8 million on the Riverdale property, the previously outstanding mortgage of approximately $4.3 million on the SF Bay Area -Vallejo property and for general corporate purposes.
In July 2014, we borrowed an additional $10 million on the KeyBank Revolver, bringing the total outstanding amount to $99 million.
The KeyBank Revolver has an initial term of three years, maturing on October 25, 2016, with two one-year extension options subject to certain conditions outlined further in the credit agreement for the KeyBank Revolver (the “Credit Agreement”). Payments under the KeyBank Revolver are interest-only for the life of the loan. The KeyBank Revolver bears interest at the Borrower’s option of either the Alternate Base Rate plus the Applicable Rate or the Adjusted LIBO Rate plus the Applicable Rate (each as defined in the Credit Agreement). The Applicable Rate will vary based on our total leverage ratio. We have elected the Adjusted LIBO Rate plus the Applicable Rate to apply to our balance outstanding. The $45 million interest rate swap originally purchased in connection with the Second Restated KeyBank Loan remained in place through December 24, 2014, thus fixing the rate on $45 million at approximately 2.4% during that period. Commensurate with the expiration of our interest rate swap, we entered into an interest rate cap, with a notional amount of $75 million, which limits the underlying index rate on our LIBO based loan to a maximum of 1% through June 30, 2015.
During the first 18 months of the KeyBank Revolver, we may request increases in the aggregate commitment up to a maximum of $200 million in minimum increments of $10 million. We may also reduce the aggregate commitment in minimum increments of $10 million during the life of the loan, provided, however, that at no time will the aggregate commitment be reduced to less than $25 million unless the KeyBank Revolver is paid in full.
The KeyBank Revolver is secured by cross-collateralized first mortgage liens or first lien deeds of trust on the properties in the Homeland Portfolio, the properties in the Knoxville Portfolio, and nine of our other self storage properties, and is cross-defaulted to any recourse debt of $25 million or greater in the aggregate or non-recourse debt of $75 million or greater in the aggregate. The KeyBank Revolver may be prepaid or terminated at any time without penalty, provided, however, that KeyBank and any other lender shall be indemnified for any breakage costs associated with any LIBOR borrowings. Pursuant to that certain guaranty dated October 28, 2013 in favor of KeyBank, we serve as a guarantor of all obligations due under the KeyBank Revolver.
Under certain conditions, the Borrower may cause the release of one or more of the properties serving as collateral for the KeyBank Revolver in connection with a full or partial pay down of the KeyBank Revolver, provided that there shall at all times be at least four properties serving as collateral.
The KeyBank Revolver contains a number of other customary terms and covenants, including the following (capitalized terms are as defined in the Credit Agreement):
	•		the aggregate borrowing base availability under the KeyBank Revolver 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 of at least $250 million; (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 sixty percent (60%); and (7) a Debt Service Coverage Ratio of not less than 1.35 to 1.0.
Second Restated KeyBank Loan
On December 27, 2011, in connection with the acquisition of the Homeland Portfolio (an $80 million portfolio of 10 properties in Atlanta, Georgia and two properties in Jacksonville, Florida), our Operating Partnership and various property owning SPEs entered into a second amended and restated secured credit facility with KeyBank with total commitments of $82 million (such facility replaced our then existing $30 million Restated KeyBank Credit Facility, which had approximately $20 million outstanding before the purchase of the Homeland Portfolio) and we drew down an additional approximately $56.6 million thereunder. On January 12, 2012, we drew down an additional approximately $5.4 million in connection with the repayment of the previously outstanding debt on our Crescent Springs, Florence and Walton properties, bringing the total amount outstanding to $82 million. Such credit facility, as amended (the “Second Restated KeyBank Loan”) was converted from a revolving credit facility to a term loan on August 15, 2012 and the principal balance was reduced on October 10, 2012, from $82 million to $55 million, through the use of the majority of the proceeds from the KeyBank CMBS Loan.
Beginning on November 30, 2012, we were required to make monthly payments in the amount of $1,666,667 until the outstanding principal balance of the Second Restated KeyBank Loan was reduced to $45 million, which occurred on April 5, 2013. The remaining $45 million was due to mature on December 24, 2014, subject to two, one-year extension options (subject to the fulfillment of certain conditions), and required monthly interest-only payments.
We were required to purchase an interest rate swap with a notional amount of $45 million, which required us to pay an effective fixed interest rate of approximately 5.41% on the hedged portion of the debt. For the remaining amount outstanding, under the terms of the Second Restated KeyBank Loan, our Operating Partnership had the option of selecting one of three variable interest rates which had applicable spreads.
The Second Restated KeyBank Loan was paid in full on October 28, 2013 with proceeds from the KeyBank Revolver.
KeyBank Bridge Loan
On October 31, 2014, SSTI Preferred Investor, LLC (the “SSTI Preferred Investor”), a wholly-owned subsidiary of our Operating Partnership, entered into a bridge term loan, as amended, (the “KeyBank Bridge Loan”) obtained from KeyBank as lender and Administrative Agent and Fifth Third Bank as co-lender. The SSTI Preferred Investor entered into the KeyBank Bridge Loan to fund its preferred equity investments (the “Preferred Equity Investments”) in the operating partnerships of SSGT and SST II.
Under the terms of the KeyBank Bridge Loan, the SSTI Preferred Investor may borrow up to $80 million. As of December 31, 2014 approximately $17 million was outstanding, of which $12 million was funded at closing and $5 million was funded on November 5, 2014. The KeyBank Bridge Loan may be fully funded through a maximum of seven draws no later than April 30, 2015. Amounts repaid under the KeyBank Bridge Loan may not be redrawn. Subsequent to December 31, 2014, additional borrowings under the KeyBank Bridge Loan were made. See Note 14 Subsequent Events.
The KeyBank Bridge Loan has an initial term of 364 days, maturing on October 30, 2015 (the “Maturity Date”). The SSTI Preferred Investor may extend the Maturity Date to April 30, 2016, subject to certain conditions outlined further in the credit agreement for the KeyBank Bridge Loan (the “Credit Agreement”). Payments due pursuant to the KeyBank Bridge Loan are interest-only for the life of the loan and are due monthly. The KeyBank Bridge Loan bears interest at the SSTI Preferred Investor’s option of either (i) LIBOR plus 650 basis points (“LIBOR”); or (ii) Alternate Base Rate plus 550 basis points (each as defined in the Credit Agreement). The SSTI Preferred Investor elected to have the LIBOR apply to its draws, which equated to an initial interest rate of approximately 6.66%.
The SSTI Preferred Investor must reduce the principal amount of the KeyBank Bridge Loan to no greater than the amounts and on the corresponding dates provided below, commencing on the date that is the earlier of (a) the last day of the second month following the acquisition of the last Portfolio Property (as defined in the Credit Agreement) by SSGT Operating Partnership, or SST II Operating Partnership; or (b) May 31, 2015 (such date, (a) or (b), is the “Curtailment Date”). As not all of the Portfolio Properties had closed as of February 28, 2015, the Curtailment Date will be May 31, 2015. Such reductions may be satisfied through (i) principal paydowns or (ii) a termination by the SSTI Preferred Investor of a portion of the undrawn commitment amount by notice to KeyBank or any combination of (i) and (ii).
Curtailment Date:		$	77 million
Curtailment Date plus two months:		$	71 million
Curtailment Date plus four months:		$	61 million
Curtailment Date plus six months:		$	49 million
Curtailment Date plus eight months:		$	37 million
Curtailment Date plus ten months:		$	25 million
Curtailment Date plus twelve months, until the Maturity Date (as it may be extended):		$	11 million
The KeyBank Bridge Loan is secured by a perfected lien on the Preferred Equity Investments (see Note 8 for additional information). The KeyBank Bridge Loan may be prepaid or terminated at any time without penalty; provided, however, that KeyBank shall be indemnified for any breakage costs associated with any LIBOR borrowings. Pursuant to that certain guaranty dated October 31, 2014 in favor of KeyBank, we serve as a guarantor of all obligations due under the KeyBank Bridge Loan.
The KeyBank Bridge Loan contains a number of other customary terms and covenants, including the following (capitalized terms are as defined in the Credit Agreement):
The SSTI Preferred Investor and the Company must meet the following financial tests, on a consolidated basis and calculated as of the close of each fiscal quarter: (1) a Total Leverage Ratio of no more than 60%; (2) a Tangible Net Worth of at least $250 million; (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; and (5) a ratio of varying rate Indebtedness to total Indebtedness not in excess of 30%.
The following table presents the future principal payment requirements on outstanding debt as of December 31, 2014:

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Note 7. Derivative Instruments
	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 or interest rate caps as part of our interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for us making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of the change in the fair value of the derivative designated and 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. During 2014 and 2013, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings, of which there was none during the years ended December 31, 2014 and 2013.
	Commensurate with the expiration of our interest rate swap, we entered into an interest rate cap, with a notional amount of $75 million, which limits the underlying index rate on our LIBOR based loan to a maximum of 1% through June 30, 2015.
	As of December 31, 2014, we had one derivative outstanding, which was an interest rate cap derivative:

	Certain of our prior agreements with our derivative counterparties contained provisions where if we either defaulted or were capable of being declared in default, including default where repayment of the indebtedness had not been accelerated, on any of our indebtedness, then we could have been declared in default on our derivative obligations.
	Certain of our prior agreements with our derivative counterparties contained provisions where if a specified event or condition (Credit Event Upon Merger) occurred that materially changed our creditworthiness in an adverse manner, we could have been required to fully collateralize our obligations under the derivative instrument.

Related Party Transactions [Abstract]
Related Party Transactions	Note 8. Related Party Transactions
	Through the closing of the Self Administration and Investment Management Transaction, effective August 31, 2014, we were a party to and incurred expenses under the following agreements for the years ended December 31, 2014, 2013 and 2012.
	Fees to Affiliates
	Our Former Advisory Agreement with our Former Advisor and dealer manager agreement (“Dealer Manager Agreement”) with our Dealer Manager entitled our Former Advisor and our Dealer Manager to specified fees upon the provision of certain services with regard to the Offering, as well as reimbursement for organizational and offering costs incurred by our Former Advisor on our behalf and entitled our Former Advisor to specified fees upon the investment of funds in real estate properties, among other services and reimbursement of certain costs and expenses incurred by our Former Advisor in providing services to us.
	Advisory Agreement
	Prior to the Self Administration and Investment Management Transaction, we did not have any employees. Our Former Advisor was primarily responsible for managing our business affairs and carrying out the directives of our board of directors. Our Former Advisor received various fees and expenses under the terms of our Former Advisory Agreement. Our Former Advisory Agreement also required our Former Advisor to reimburse us to the extent that offering expenses, including sales commissions, dealer manager fees and organization and offering expenses, were in excess of 15% of gross proceeds from the Offering. Subsequent to the termination of our Offering on September 22, 2013, we have determined that these expenses did not exceed 15% of gross proceeds from the Offering. In addition, certain organization and offering costs of the Offering were paid by our Former Advisor on our behalf and reimbursed to our Former Advisor from the proceeds of the Offering. Organization and offering costs consisted of all expenses (other than sales commissions and the dealer manager fee) 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 offering expenses, including, but not limited to, (i) amounts to reimburse our Former Advisor for all marketing related costs and expenses such as salaries and direct expenses of employees of our Former 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 Former Advisor was required to reimburse us within 60 days after the end of the month which the Offering terminates to the extent we paid or reimbursed organization and offering costs (excluding sales commissions and dealer manager fees) in excess of 3.5% of the gross offering proceeds from the Primary Offering. Subsequent to the termination of our Offering on September 22, 2013, we have determined that organization and offering costs did not exceed 3.5% of the gross proceeds from the Primary Offering.
	Our Former Advisor received acquisition fees equal to 2.5% of the contract purchase price of each property we acquired plus reimbursement of any acquisition expenses the Former Advisor incurred. Our Former Advisor also received a monthly asset management fee equal to one-twelfth of 1.0% of the average of the aggregate asset value, as defined in the Former Advisory Agreement, of our assets, excluding those properties acquired through our mergers with REIT I and REIT II and the SS I, DST, Madison DST, Colonial DST and SF DST acquisitions; provided, however, that if the average of the aggregate asset value, as defined, of our assets exceeded $500 million, the monthly asset management fee would be reduced to one-twelfth of 0.75% of the average of the aggregate asset value, as defined, of those assets exceeding $500 million unless our modified funds from operations (as defined in the Former Advisory Agreement), including payment of the fee, was greater than 100% of our distributions in any month (see footnote (2) in the following table for a discussion of the Former Advisor’s permanent waiver of certain asset management fees). The monthly asset management fees for our properties acquired through our mergers with REIT I and REIT II and the SS I, DST, Madison DST, Colonial DST and SF DST acquisitions was equal to 2.0% of the gross revenues from the properties and was paid to affiliates of our Former Sponsor. Under our Former Advisory Agreement, and our articles of incorporation, as amended, our Former Advisor may have received disposition fees in an amount equal to the lesser of (i) 3.0% of the contract sale price for each property we sell, or (ii) one-half of the competitive real estate commission, as long as our Former Advisor provided substantial assistance in connection with the sale. The disposition fees paid to our Former Advisor were subordinated to the receipt of our stockholders of a 6% cumulative, non-compounded, annual return on such stockholders’ invested capital. The total real estate commissions paid (including disposition fees paid to our Former Advisor) may not have exceeded the lesser of a competitive real estate commission or an amount equal to 6.0% of the contract sale price of the property.
	Our Former Advisory Agreement provided for reimbursement of our Former Advisor’s direct and indirect costs of providing administrative and management services to us (see footnote (1) in the following table for a discussion of the Former Advisor’s permanent waiver of certain reimbursements). Beginning October 1, 2009 (four fiscal quarters after the acquisition of our first real estate asset), our Former Advisor was required to reimburse us the amount by which our aggregate annual operating expenses, as defined, exceeded the greater of 2% of our average invested assets or 25% of our net income, as defined, unless a majority of our independent directors determined 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 exceeded the limitation, we were required to 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 was required to include an explanation of the factors that the independent directors considered in arriving at the conclusion that the excess expenses were justified. Our aggregate annual operating expenses, as defined, did not exceed the thresholds described above.
	On September 27, 2012, we entered into a Second Amended and Restated Advisory Agreement (the “Amended Advisory Agreement”) with our Former Advisor. The material terms of the Former Advisory Agreement were not changed. However, certain provisions were added, the most significant of which was a provision restricting us, during the term of the Amended Advisory Agreement and for a period of two years after the termination of the Amended Advisory Agreement, from soliciting or hiring any employee of, or person performing services on behalf of, our Former Advisor.
	On March 28, 2014, in a series of related transactions, we entered into an amended and restated advisory agreement (the “Third Amended and Restated Advisory Agreement”) and an amended and restated limited partnership agreement (the “Second Amended and Restated Limited Partnership Agreement”), and REIT I and REIT II entered into amendments to their respective operating partnership agreements, (the “First REIT I OP Agreement Amendment” and the “First REIT II OP Agreement Amendment,” respectively). REIT I and REIT II are each wholly-owned by our Operating Partnership.
	The Third Amended and Restated Advisory Agreement with our Former Advisor and our Operating Partnership amended and superseded the Second Amended and Restated Advisory Agreement. Pursuant to the Third Amended and Restated Advisory Agreement, provisions related to various subordinated fees that would be due to our Former Advisor upon the occurrence of certain events were removed from such agreement and were included in the Second Amended and Restated Limited Partnership Agreement of our Operating Partnership. Additionally, our Operating Partnership became a party to the Third Amended and Restated Advisory Agreement and provided customary representations and warranties, and certain provisions of the Second Amended and Restated Limited Partnership Agreement were incorporated into the Third Amended and Restated Advisory Agreement.
	The Second Amended and Restated Limited Partnership Agreement with our Operating Partnership and our Former Advisor amended and superseded the First Amended and Restated Limited Partnership Agreement. Pursuant to the Second Amended and Restated Limited Partnership Agreement, our Former Advisor and the advisors to REIT I and REIT II were each granted a special limited partnership interest in our Operating Partnership and each became a party to the Second Amended and Restated Limited Partnership Agreement. In addition, provisions related to various subordinated fees that would be due to our Former Advisor upon the occurrence of certain events were included in such agreement and were payable as distributions pursuant to our Former Advisor’s special limited partnership interest. After giving effect to the Second Amended and Restated Limited Partnership Agreement, the First REIT I OP Agreement Amendment, and the First REIT II OP Agreement Amendment, our Former Advisor and the advisors to REIT I and REIT II became entitled to receive various potential subordinated distributions, each of which were outlined further in the Second Amended and Restated Limited Partnership Agreement, the First REIT I OP Agreement Amendment, and the First REIT II OP Agreement Amendment, if (1) our shares of common stock were listed on a national exchange, (2) we terminated our Former Advisory Agreement (other than a voluntary termination by mutual assent), (3) we liquidated our portfolio, or (4) we entered into an Extraordinary Transaction, as defined in such agreements. In the case of each of the foregoing distributions, our Former Advisor’s receipt of the distribution is subordinate to return of capital to our stockholders plus at least a 6% cumulative, non-compounded return, and our Former Advisor’s share of the distribution was 5%, 10%, or 15%, depending on the return level to our stockholders. The receipt of the distribution by the former advisors to REIT I and REIT II is subordinate to return of capital to the original REIT I and REIT II stockholders plus at least a 7% cumulative, non-compounded return, and such advisors’ share of the distribution was 15%. In addition, our Former Advisor was potentially entitled to a one-time cash distribution in the event that we (1) listed our shares of common stock on a national exchange, (2) liquidated our portfolio, or (3) entered into an Extraordinary Transaction resulting in a return to our stockholders in excess of an amount per share that will be determined by our independent directors. Such one-time cash distribution would be paid as part of the complete redemption of our Former Advisor’s special limited partnership interest in our Operating Partnership and would be up to the aggregate amount of all unreturned and unreimbursed capital invested by our Former Advisor and its affiliates in us, our Operating Partnership, our Former Advisor and affiliates, relating in any way to our business or our Operating Partnership’s business or any offering.
	Dealer Manager Agreement
	During the term of our Offering, our Dealer Manager received a sales commission of up to 7.0% of gross proceeds from sales in the Primary Offering and a dealer manager fee equal to up to 3.0% of gross proceeds from sales in the Primary Offering under the terms of our Dealer Manager Agreement. 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 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 the 3.0% 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 cannot be justified, any excess over actual due diligence expenses will be considered underwriting compensation subject to a 10% FINRA limitation and, when aggregated with all other non-accountable expenses, may not exceed 3% of gross offering proceeds from sales in the Primary Offering. The Dealer Manager Agreement terminated upon the termination of our Offering.
	Prior to the Self Administration and Investment Management Transaction, our Chief Executive Officer, through a wholly-owned limited liability company, owned a 15% non-voting equity interest in our Dealer Manager. We acquired that equity interest through the Self Administration and Investment Management Transaction
	Property Management Agreement
	Our Property Manager received and was entitled to certain fees up to the date of our acquisition of our Property Manager through the Self Administration and Investment Management Transaction. Our Property Manager received a fee for its services in managing our properties, generally equal to 6% of the gross revenues from the properties plus reimbursement of the direct costs of managing the properties under our property management agreement. In the event that our Property Manager assisted with the development or redevelopment of a property, we may have been required to pay a separate market-based fee for such services. As a condition of the REIT II merger transaction, our Property Manager agreed to waive the monthly property management fees for the REIT II properties until the FFO, as defined in the merger agreement, of those properties reached $0.70 per share (which threshold was met in the three months ended March 31, 2013).
	On September 27, 2012, our board of directors approved revisions to our property management agreements entered into with respect to properties acquired after that date. These revisions included increasing the term to three years, with automatic three-year extensions; revising the property owner’s obligation to reimburse the Property Manager for certain expenses; the addition of a construction management fee (as defined); the addition of a tenant insurance administrative fee; adding a nonsolicitation provision; and adding a provision regarding the Property Manager’s use of trademarks and other intellectual property owned by SSH.
	Pursuant to the terms of the agreements described above, the following summarizes the related party costs incurred for the years ended December 31, 2014, 2013 and 2012:
			Year Ended		Year Ended		Year Ended

	(1)	During the years ended December 31, 2013 and 2012, our Former Advisor permanently waived certain reimbursable indirect costs, primarily payroll and related overhead costs, related to administrative and management services, totaling approximately $975,000 and $960,000, respectively. Such amounts were waived permanently and accordingly, will not be paid to our Former Advisor. During the eight months ended August 31, 2014 and three months ended December 31, 2013 our Former Advisor did not waive reimbursable indirect costs, and such reimbursable indirect costs totaled approximately $745,000 and $340,000, respectively, for such periods.

During the eight months ended August 31, 2014 and three month period ended December 31, 2013 such amounts were not waived and approximately $470,000 and $175,000, respectively, of such costs were recorded. During the year ended December 31, 2012, our Former Advisor permanently waived asset management fees related to the Stockade Portfolio and our Dufferin property totaling approximately $186,000 and $37,000, respectively. Such amounts were waived permanently and accordingly, will not be paid to our Former Advisor.
	(3)	During the years ended December 31, 2013 and 2012, property management fees include approximately $27,000 and $100,000, respectively, of fees paid to the sub-property manager of our Canadian properties. Such sub-property management agreement was terminated effective March 31, 2013 at a cost of approximately $28,000.
	(4)	During the eight months ended August 31, 2014 and the year ended December 31, 2013, our Property Manager permanently waived certain costs, reimbursements and fees, including construction management fees, tenant insurance administration fees and expense reimbursements related to certain off-site property management employees. Such amounts totaled approximately $560,000 and $759,000, respectively. These amounts were waived permanently and accordingly, will not be paid to our Property Manager.
	As of December 31, 2013, we had amounts due to affiliates totaling approximately $1,742,000. As of December 31, 2014 we had amounts due from affiliates totaling approximately $56,000 which is included in the other assets line item of our consolidated balance sheet.
	Investment Management Transactions
	Effective August 31, 2014, our Operating Partnership acquired Strategic Storage Realty Group, LLC, the parent company of the advisors and property managers for SST II and SSGT, as part of the Self Administration and Investment Management Transaction. As a result, we are now their sponsor and will be entitled to receive various fees and expense reimbursements discussed below from the Managed REITs.
	As of December 31, 2014, SSGT owned three self storage properties and SST II owned five self storage properties.
	Advisory Agreement Fees
	Our indirect subsidiaries, Strategic Storage Advisor II, LLC, the advisor to SST II, and SS Growth Advisor, LLC, the advisor to SSGT, are entitled to receive various fees and expense reimbursements under the terms of the SST II and SSGT advisory agreements. However, in connection with the Self Administration and Investment Management Transaction, we, the Operating Partnership and SSH agreed, under the Acquisition Fee Tail Agreement, that for a period of six months following the closing of the Self Administration and Investment Management Transaction, subject to certain extensions, SSH, as the former ultimate parent company of Strategic Storage Advisor II, LLC and SS Growth Advisor, LLC, will retain any and all acquisition fees that would have been due under their respective advisory agreements with respect to any properties whose acquisition was pending, under contract, or was otherwise in process as of the closing of the Self Administration and Investment Management Transaction (See Note 3).
	SST II Advisory Agreement
	Strategic Storage Advisor II, LLC (the “SST II Advisor”) provides acquisition and advisory services to SST II pursuant to an advisory agreement (the “SST II Advisory Agreement”). SST II is required to reimburse SST II Advisor for organization and offering costs under the SST II Advisory Agreement; provided, however, the SST II Advisor will be required to reimburse SST II within 60 days after the end of the month in which the SST II public offering terminates to the extent SST II paid or reimbursed organization and offering costs (excluding sales commissions and dealer manager fees) in excess of 3.5% of the gross offering proceeds from the SST II offering. The SST II Advisory Agreement also requires the SST II Advisor to reimburse SST II to the extent that offering expenses, including sales commissions, dealer manager fees and organization and offering expenses, are in excess of 15% of gross proceeds from the SST II offering.
	Subject to the Acquisition Fee Tail Agreement, the SST II Advisor will receive acquisition fees equal to 1.75% of the contract purchase price of each property SST II acquires plus reimbursement of any acquisition expenses that SST II Advisor incurs. The SST II Advisor will also receive a monthly asset management fee equal to 0.05208%, which is one-twelfth of 0.625%, of SST II’s aggregate asset value, as defined.
	Under the SST II Advisory Agreement, the SST II Advisor will receive 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 SST II sells, as long as the SST II Advisor provides substantial assistance in connection with the sale. The total real estate commissions paid (including the disposition fee paid to the SST II 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 and are subordinated to receipt of the SST II stockholders of a 6% cumulative, non-compounded, annual return on such stockholders’ invested capital. The SST II Advisor may potentially also be entitled to various subordinated distributions under the SST II operating partnership agreement if SST II (1) lists its shares of common stock on a national exchange, (2) terminates the SST II Advisory Agreement, (3) liquidates its portfolio, or (4) enters into an Extraordinary Transaction, as defined in the SST II operating partnership agreement.
	The SST II Advisory Agreement provides for reimbursement of the SST II Advisor’s direct and indirect costs of providing administrative and management services to SST II. Beginning four fiscal quarters after SST II acquires its first real estate asset (which occurred on November 4, 2014) the SST II Advisor will be required to pay or reimburse SST II the amount by which SST II’s aggregate annual operating expenses, as defined, exceed the greater of 2% of SST II’s average invested assets or 25% of SST II’s net income, as defined, unless a majority of SST II’s independent directors determine that such excess expenses were justified based on unusual and non-recurring factors.
	SSGT Advisory Agreement
	SS Growth Advisor, LLC (the “SSGT Advisor”) provided acquisition and advisory services to SSGT pursuant to an advisory agreement in connection with the private placement offering (the “SSGT Private Offering Advisory Agreement”). On January 20, 2015 the SSGT Advisor entered into a substantially similar advisory agreement in connection with the public offering (the “SSGT Public Offering Advisory Agreement” and, together with the Private Offering Advisory Agreement, the “SSGT Advisory Agreements”). SSGT is required to reimburse the SSGT Advisor for organization and offering costs from the SSGT private offering and the SSGT public offering pursuant to the SSGT Advisory Agreements; provided, however, pursuant to the SSGT Public Offering Advisory Agreement, the SSGT Advisor will be required to reimburse SSGT within 60 days after the end of the month in which the SSGT public offering terminates to the extent SSGT paid or reimbursed organization and offering costs (excluding sales commissions and dealer manager fees) in excess of 3.5% of the gross offering proceeds from the SSGT primary offering.
	The SSGT Public Offering Advisory Agreement also requires the SSGT Advisor to reimburse SSGT to the extent that offering expenses, including sales commissions, dealer manager fees and organization and offering expenses, are in excess of 15% of gross proceeds from the SSGT public offering. The SSGT Advisor will receive acquisition fees equal to 1% and 1.75% (subject to the Acquisition Fee Tail Agreement), respectively, of the contract purchase price of each property SSGT acquires plus reimbursement of any acquisition expenses the SSGT Advisor incurs pursuant to the SSGT Private Offering Advisory Agreement and the SSGT Public Offering Advisory Agreement. The SSGT Advisor will also receive a monthly asset management fee equal to 0.04167%, which is one-twelfth of 0.5%, of SSGT’s aggregate asset value, as defined. SSGT may also pay the SSGT Advisor a financing fee of up to 0.5% of the borrowed amount of a loan for arranging for financing in connection with the acquisition, development or repositioning of SSGT’s properties.
	Under the Public Offering Advisory Agreement, the SSGT Advisor will receive 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 SSGT sells, as long as the SSGT Advisor provides substantial assistance in connection with the sale. As provided under the SSGT Public Offering Advisory Agreement, the total real estate commissions paid (including the disposition fee paid to the SSGT 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. SSGT will also pay the SSGT Advisor or its affiliate a market-based development fee some or all of which may be reallowed to a third party developer. The development fee will be paid in connection with properties that SSGT anticipates developing or expanding within 12 months of the acquisition of such properties. A development fee to a third party developer may take the form of an up-front fee and participation in a back-end performance fee. The SSGT Advisor may also be potentially entitled to various subordinated distributions under SSGT’s operating partnership agreement if SSGT (1) lists its shares of common stock on a national exchange, (2) terminates the SSGT Public Offering Advisory Agreement, (3) liquidates its portfolio, or (4) merges with another entity or enters into an Extraordinary Transaction, as defined in the SSGT operating partnership agreement.
	The SSGT Advisory Agreements provide for reimbursement of the SSGT Advisor’s direct and indirect costs of providing administrative and management services to SSGT. Beginning four fiscal quarters after SSGT acquires its first real estate asset (which occurred on July 31, 2014), pursuant to the SSGT Public Offering Advisory Agreement, the SSGT Advisor will be required to pay or reimburse SSGT the amount by which SSGT’s aggregate annual operating expenses, as defined, exceed the greater of 2% of SSGT’s average invested assets or 25% of its net income, as defined, unless a majority of SSGT’s independent directors determine that such excess expenses were justified based on unusual and non-recurring factors.
	Property Management Agreements
	Commencing September 1, 2014, our indirect subsidiaries, Strategic Storage Property Management II, LLC and SS Growth Property Management, LLC (collectively the “Managed REITs Property Managers”), are entitled to receive fees for their services in managing the properties owned by the Managed REITs pursuant to property management agreements entered into between the owner of the property and the applicable Managed REIT’s Property Manager. The Managed REITs Property Managers will receive a property management fee equal to 6% of the gross revenues from the properties, generally subject to a monthly minimum of $3,000 per property, plus reimbursement of the costs of managing the properties. Reimbursable costs and expenses include wages and salaries and other expenses of employees engaged in operating, managing and maintaining such properties. Pursuant to the property management agreements, we through our Operating Partnership employ the on-site staff for the Managed REITs’ properties. For the year ended December 31, 2014 such payroll related costs totaled approximately $0.1 million.
	In the event that a Managed REITs Property Manager assists with the development or redevelopment of a property owned by a Managed REIT, a Managed REITs Property Manager may be entitled to receive a separate market-based fee for such services. In addition, a Managed REITs Property Manager will be entitled to a construction management fee equal to 5% of the cost of a related construction or capital improvement work project in excess of $10,000 and an administration fee equal to $0.50 a month for each insurance policy purchased by a customer at one of the Managed REITs’ properties in connection with the tenant insurance program.
	Summary of Fees and Reimbursable Costs

Other Related Party Transactions
Tenant Reinsurance Program
Beginning in 2011, our Chief Executive Officer and President, through certain entities, began participating in a tenant reinsurance program whereby tenants of our self storage facilities are able to purchase insurance to cover damage or destruction to their property while stored at our facilities. Such entities invested in a Cayman Islands company (the “Reinsurance Company”) that reinsures a portion of the insurance required by the program insurer to cover the risks of loss at participating facilities in the program. The program insurer provides fees (approximately 50% of the tenant premium paid) to us as owner of the facilities. The Reinsurance Company may be required to fund additional capital or may be entitled to receive distributions of profits depending on actual losses incurred under the program. Effective August 31, 2014, we acquired such interest from our Chief Executive Officer and President (See Note 3). For the years ended December 31, 2014, 2013 and 2012, we recorded revenue of approximately $1.3 million, $1.6 million and $1.3 million respectively, in connection with this tenant reinsurance program while it was owned by such affiliates. For the year ended December 31, 2014, we recorded approximately $0.7 million in revenue from the program insurer, while we owned the tenant reinsurance interest.
Storage Auction Program
During the second quarter of 2013, our Chief Executive Officer and President, and our Senior Vice President – Property Management and the President of our Property Manager, purchased noncontrolling interests in a company (the “Auction Company”) that serves as a web portal for self storage companies to post their auctions online instead of using live auctions conducted at the self storage facilities. Once the contents of a storage unit are sold at auction, we pay the Auction Company a service fee based upon the sale price of the unit. On January 1, 2014, the Auction Company merged with another similar company. Such officers’ collective ownership in the new combined company is now approximately nine percent. For the years ended December 31, 2014 and 2013, we incurred approximately $125,000 and $50,000, respectively, in auction fees with the Auction Company.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Based Compensation	Note 9. Stock Based Compensation
	We issue stock based compensation pursuant to the “Employee and Director Long-Term Incentive Plan of Strategic Storage Trust, Inc.” (the “Plan”), which was effective as of February 25, 2008. To date we have only issued restricted stock grants, which are subject to a vesting period over which the restrictions are released and the stock is issued in book entry form to the grantee. During the vesting period, the grantee is not permitted to sell, transfer, pledge, encumber or assign shares of non-vested restricted stock granted under the Plan and the grantee does not have the ability to vote the shares. Any dividends paid on non-vested shares will be paid, if and when the underlying restricted shares vest. Generally the shares vest over an approximate four-year period which begins on the date of grant. Beginning with the 2014 grants to our independent, non-employee board of directors, such grants vest over an approximate one-year period.
	As of December 31, 2014, 5,727,586 shares were available for issuance under the Plan.
	We recorded approximately $32,000, $26,000 and $25,000 of expense in general and administrative expense in our statement of operations related to restricted stock granted to employees and directors for the years ended December 31, 2014, 2013 and 2012, respectively. As of December 31, 2014 there was approximately $0.6 million of total unrecognized compensation expense related to non-vested restricted stock awards.

Commitments and Contingencies	Note 10. Commitments and Contingencies
	Distribution Reinvestment Plan
	We adopted a distribution reinvestment plan that allowed our stockholders to have distributions otherwise distributable to them invested in additional shares of our common stock. The plan became effective on the effective date of our Initial Offering. The purchase price per share was the higher of $9.50 per share or 95% of the fair market value of a share of our common stock. On March 28, 2012, the purchase price per share under the distribution reinvestment plan was changed to 95% of the offering price of our shares. On September 18, 2013, our board of directors amended and restated our distribution reinvestment plan to change the purchase price per share from 95% of the offering price to approximately $10.25 (which resulted in the same price as prior to this amendment and restatement) and make other certain minor revisions related to the closing of our Offering, including granting to our board of directors the authority to set or change the purchase price at any time in its sole and absolute discretion based upon such factors as it deems appropriate. On September 4, 2014, our board of directors approved an estimated value per share of our common stock of $10.81, based on our net asset value divided by the number of shares outstanding on an adjusted fully diluted basis, calculated as of June 30, 2014. In connection with the new estimated value per share, and pursuant to its authority to change the share purchase price, our board of directors approved a share price of approximately $10.27 per share (95% of the $10.81 estimated value per share) for shares offered pursuant to our distribution reinvestment plan, effective as of September 4, 2014.
	Following the termination of our Offering, on September 22, 2013, we filed with the SEC a Registration Statement on Form S-3, which incorporated the amended and restated distribution reinvestment plan and registered up to an additional $51.25 million in shares. The Form S-3 allows us to continue to offer shares pursuant to our amended and restated distribution reinvestment plan beyond September 22, 2013; however we may amend or terminate the plan at any time upon 10 days’ prior written notice to stockholders. The plan was effective as of September 28, 2013.
	No sales commission or dealer manager fee will be paid on shares sold through the distribution reinvestment plan. As of December 31, 2014, we have sold approximately 2.2 million shares through our DRP Offering.
	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. The holders of the Class D Units have agreed to modified exchange rights that prevent them from exercising their exchange rights: (1) until the earlier of (a) a listing of our shares or (b) our merger into another entity whereby our stockholders receive securities listed on a national securities exchange; or (2) until FFO of the properties contributed by the holders of the Class D Units reaches $0.70 per share, based on our fully-loaded cost of equity. 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. The Class B Units shall be converted on a per unit basis into OP Units at the later of (i) two years from the date of issuance, or (ii) the date on which the OP Units have a fully diluted estimated net asset value per unit (after giving effect to the conversion of the Class B Units) exceeding $10.81, calculated in accordance with the provisions of Practice Guideline 2013-01, Valuations of Publicly Registered Non-Listed REITs, issued by the Investment Program Association (IPA) in April 2013 (the “IPA Guidelines”); provided, however, that the estimated net asset value per unit shall take into account the value of the assets acquired by the Operating Partnership, pursuant to the SSH Contribution Agreement and the Churchill Contribution Agreement. The Class B Units shall be automatically converted into OP Units in the event of a change in control or listing event (with market value in a listing measured by the average closing price during a 30-day period commencing at any time between 180 days and 540 days following listing) at a price in excess of $10.81 per share. The Class B Units shall only be converted to the extent that, after giving effect to such conversion, the value of a share in the event of a change in control or listing event is greater than $10.81.
	In connection with the Self Administration and Investment Management Transaction, pursuant to the terms of the SSH Contribution Agreement, Churchill Contribution Agreement and Limited Partner Interest Contribution Agreement, none of SSH, Churchill, the Former Advisor, the REIT I Advisor or the REIT II Advisor may transfer for a period of two years any of (a) the OP Units or Class B Units it receives pursuant to the SSH Contribution Agreement, Churchill Contribution Agreement or the Limited Partner Interest Contribution Agreement, as applicable, or (b) any shares of our common stock held by any of them upon exchange of the OP Units or Class B Units pursuant to the provisions of the Operating Partnership Agreement, except for certain permitted transfers, and, upon a change in control, such restrictions on transfer shall terminate.
	Ground Lease Commitment – SF Bay Area – San Lorenzo
	In connection with the acquisition of our SF Bay Area – San Lorenzo property, we assumed a land lease, with a remaining term of approximately 21 years as of December 31, 2014, subject to one 35 year extension option, and recorded rent expense of approximately $147,000 for the year ended December 31, 2014. The lease has minimum lease payments of approximately $139,000, $139,000, $139,000, $139,000, $139,000 and $2,415,000 for the years ending 2015, 2016, 2017, 2018, 2019 and thereafter respectively.
	Corporate Office Lease
	In connection with the Self Administration and Investment Transaction we assumed a lease for our corporate office in Ladera Ranch, California for approximately 10,000 square feet. The lease extends through December 2017. The lease has minimum lease payments of approximately $221,000, $227,000 and $234,000 for the years ending 2015, 2016 and 2017, respectively.
	Greater Toronto Area Development
	In connection with our development properties (Mississauga, Brampton, Centennial and Pickering) in the Greater Toronto Area we entered into development services agreements with a third party to assist us with the development process. In addition to development fees the firm was paid, they will be entitled to a defined percentage of the net cash flow related to the property, if the property generates in excess of a certain current return on our invested capital. Additionally, if the property is sold and our compounded internal rate of return on our invested capital exceeds a defined return they will be entitled to additional amounts.
	Other Contingencies
	We are involved in routine litigation and threatened litigation arising in the ordinary course of business. While the outcome of any litigation is inherently unpredictable, we believe the likelihood of these pending legal matters having a material adverse effect on our financial condition or results of operations is remote.

	KeyBank Bridge Loan
	Subsequent to December 31, 2014, we borrowed an additional approximately $57 million on the KeyBank Bridge Loan, bringing the total outstanding amount borrowed to approximately $74 million. The proceeds of the borrowings were used to fund our investments in additional Preferred Units in SST II and SSGT, pursuant to their respective Unit Purchase Agreements (see Note 8 for additional information on the Unit Purchase Agreements).
	Investments in Managed REITs
	Subsequent to December 31, 2014, the SSTI Preferred Investor invested an additional approximately $49.9 million in Preferred Units in the SST II Operating Partnership and an additional approximately $7.2 million in Preferred Units in the SSGT Operating Partnership.
	SST II utilized the funds to purchase through its operating partnership, 21 self storage facilities in California, Colorado, Illinois, Maryland and Washington for an aggregate purchase price of approximately $110.5 million.
	SSGT utilized the funds to purchase through its operating partnership, six self storage facilities in California, Colorado and Illinois for an aggregate purchase price of approximately $15.9 million.

	Subsequent to December 31, 2014, we through an indirect wholly-owned subsidiary, entered into a purchase and sale agreement for a self storage facility located in Tempe, Arizona. The purchase price for the acquisition is approximately $4.4 million. We expect to close this acquisition by the end of the first quarter of 2015. There can be no assurance that we will complete such acquisition. In some circumstances, if we fail to complete such acquisition, we may forfeit some earnest money as a result.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
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.
	Effective September 15, 2009, the ASC was established as the single source of authoritative nongovernmental GAAP. Prior to the issuance of the ASC, all GAAP pronouncements were issued in separate topical pronouncements in the form of statements, staff positions or Emerging Issues Task Force Abstracts, and were referred to as such. While the ASC does not change GAAP, it introduces a new structure and supersedes all previously issued non-SEC accounting and reporting standards. In addition to the ASC, the Company is still required to follow SEC rules and regulations relating to the preparation of financial statements. The Company’s accounting policies are consistent with the guidance set forth by both the ASC and the SEC.
Reclassifications	Reclassifications
	Certain amounts previously reported in our 2013 financial statements have been reclassified to conform to the fiscal 2014 presentation.
Principles of Consolidation	Principles of Consolidation
	Our financial statements, the financial statements of our Operating Partnership, including its wholly-owned subsidiaries, the financial statements of Self Storage REIT, LLC (REIT I) and Self Storage REIT II, LLC (REIT II) are consolidated in the accompanying consolidated financial statements. The portion of these entities not wholly-owned by us is presented as noncontrolling interests both as of and during the periods presented. 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 (a “VIE”) and determining when a company should include the assets, liabilities, noncontrolling interests, and results of activities of the 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. As of December 31, 2014 and 2013, we had entered into contracts/interests that are deemed to be variable interests in VIEs; those variable interests include both lease agreements and equity investments. We have evaluated those variable interests against the criteria for consolidation and determined that we are not the primary beneficiary of certain investments discussed further in the “Equity Investments” section of this note.
	As of December 31, 2013, we had an equity interest in a self storage property located in San Francisco, California (“SF Property”) which was deemed to be a VIE of which we were the primary beneficiary. As such, the SF Property was consolidated in our consolidated financial statements since the date we first acquired our interest in the property through the REIT I merger. In January 2010, we acquired an approximately 2% additional interest in the SF Property, bringing our then total interest to approximately 12%. The SF Property is owned by a Delaware Statutory Trust (“DST”), and by virtue of the trust agreement the investors in the trust did not have the direct or indirect ability through voting rights to make decisions about the DST’s significant activities. The REIT I operating partnership (the “REIT I Operating Partnership”) had also entered into a lease agreement for the SF Property, in which the REIT I Operating Partnership was the tenant, which exposed it to losses of the VIE that could be significant to the VIE and also allowed it to direct activities of the VIE that determined its economic performance by means of its operation of the leased facility. In connection with the REIT I merger, our Former Sponsor entered into an agreement to indemnify us for any losses as a result of potential shortfalls in the lease payments required to be made by the REIT I Operating Partnership. Despite such indemnification, we were deemed to be the primary beneficiary, as our Former Sponsor was not deemed to have a variable interest in the SF Property.
	During January and February 2014, we acquired an additional approximately 86% of interests in the SF Property (through our acquisition of beneficial interests in the DST) from approximately 45 third-party sellers bringing our total interest to approximately 98%. During May 2014, we acquired an additional approximately 1% from one third-party seller, bringing our current ownership to approximately 99%. Given that we had consolidated the SF Property since we acquired the original interest, the acquisition of interests during 2014 were treated as acquisitions of noncontrolling interests and the SF Property has since been consolidated as a majority owned subsidiary whereas we previously consolidated it as a VIE. For additional discussion, see Note 4.
Use of Estimates	Use of Estimates
	The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States 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 adjusts such estimates when facts and circumstances dictate. 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 of assets held by equity method investees, and the useful lives of real estate assets and intangibles. Actual results could materially differ from those estimates.
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 equivalents in financial institutions in excess of insured limits, but believe this risk is 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.
Purchase Price Allocation	Purchase Price Allocation
	We account for acquisitions in accordance with accounting guidance 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 and to adjust those estimates as necessary during the measurement period (defined as the period, not to exceed one year, in which we may adjust the provisional amounts recognized for an acquisition). 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. Accordingly, to date we have not allocated any portion of the purchase price to above or below market leases. We also consider whether in-place, market leases represent an intangible asset. We recorded approximately $1.3 million and approximately $7.1 million in intangible assets to recognize the value of in-place leases related to our acquisitions in 2014 and 2013, respectively. We do not expect, nor to date have we recorded, intangible assets for the value of customer relationships because we will not have concentrations of significant customers and the average customer turnover is fairly frequent. Our acquisition-related transaction costs are required to be expensed as incurred. During the years ended December 31, 2014, 2013 and 2012 we expensed approximately $0.8 million, $2.4 million and $3.6 million, respectively, of acquisition related transaction costs.
	Should the initial accounting for an acquisition be incomplete by the end of a reporting period that falls within the measurement period, we report provisional amounts in our financial statements. During the measurement period, we adjust the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date and we record those adjustments to our financial statements. We apply those measurement period adjustments that we determine to be significant retrospectively to comparative information in our 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 will continually monitor events and changes in circumstances that could indicate that the carrying amounts of our long-lived assets, including those held through joint ventures, 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. As of December 31, 2014 and 2013, no impairment losses have been recognized.
Equity Investments	Equity Investments
	Our investments in unconsolidated real estate entities and VIEs in which we are not the primary beneficiary, where we have significant influence, but not control, are recorded under the equity method of accounting in the accompanying consolidated financial statements. Under the equity method, our investments in real estate entities are stated at cost and adjusted for our share of net earnings or losses and reduced by distributions. Equity in earnings of real estate entities are generally recognized based on the allocation of cash distributions upon liquidation of the investment in accordance with the joint venture agreements.
	Investments representing passive preferred equity and/or noncontrolling interests are accounted for under the cost method. Under the cost method, our investments in real estate ventures are carried at cost and adjusted for other-than-temporary declines in fair value, distributions representing a return of capital and additional investments.
	Through mergers with REIT I and REIT II in 2009, we acquired preferred equity and/or noncontrolling interests in unconsolidated real estate entities all of which were deemed to be VIEs. We currently have one such interest and have evaluated such interest against the amended criteria for consolidation and determined that we are not the primary beneficiary, generally due to our inability to direct significant activities that determine the economic performance of the VIE. The investment is a passive interest in two self storage facilities (such properties are owned by a DST, and by virtue of the related trust agreements, the investors have no direct or indirect ability through voting rights to make decisions about its significant activities) and is therefore accounted for under the cost method; our aggregate investment therein is approximately $0.1 million. Our ownership interest in such investment was approximately 1.49% and our risk of loss is limited to our investment therein.
	In May 2012, our equity interest in an unconsolidated joint venture which owned a self storage facility in Baltimore, Maryland was redeemed for approximately $1.4 million. This resulted in a gain of approximately $0.8 million, which is included in equity in earnings – gain related to property sale by unconsolidated entity in our Consolidated Statement of Operations for the year ended December 31, 2012.
	We own a 12% interest in Westport LAX LLC, a joint venture that originally acquired a net leased industrial property (the “Hawthorne Property”) in California. This investment is accounted for under the equity method. In July 2014 the Hawthorne Property was sold, and we received a distribution of approximately $3 million relative to our 12% ownership in Westport LAX LLC, resulting in a gain of approximately $1.9 million. The remaining carrying value of our investment therein is approximately $0.1 million.
	Hawthorne LLC, an affiliate of our Former Sponsor, owns 78% of Westport LAX LLC, and we had a preferred equity interest in Hawthorne LLC which entitled us to distributions equal to 10% per annum on our investment of approximately $6.9 million pursuant to terms of the preferred equity interest in Hawthorne LLC. In August 2014 we received our preferred investment in full along with the accumulated preferred return thereon in connection with the sale of the Hawthorne Property. The remaining 10% interest in Westport LAX LLC is owned by a third party, who was also the co-manager, along with our Former Sponsor, of the Hawthorne Property. Such third party has been and continues to be the acting manager and directed the operating activities of the property that determined its economic performance. We, along with other non-affiliated parties, were guarantors on the approximately $19 million loan that encumbered the Hawthorne Property until the property was sold in July 2014 and the loan was assumed by the buyer. As of December 31, 2014, we had no further exposure to loss as a result of our involvement with this VIE, other than our remaining investment balance of approximately $0.1 million.
Investments in and Advances to Managed REITs	Investments in and Advances to Managed REITs
	As of December 31, 2014, we owned equity investments with a carrying value of approximately $0.4 million in the Managed REITs. We account for these investments using the equity method of accounting as we have the ability to exercise significant influence, but not control, over the Managed REITs’ operating and financial policies through our advisory and property management agreements with the respective Managed REITs. The equity method of accounting requires the investment to be initially recoded at cost and subsequently adjusted for our share of equity in the respective Managed REIT’s earnings and reduced by distributions.
	Also included in investments in and advances to managed REITs are receivables from the Managed REITs of approximately $1.8 million and our investment in the preferred units in the Managed REITs, totaling approximately $16.8 million. For additional discussion, see Note 8.
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 rents contractually due but unpaid are included in other assets.
	Investment management revenue includes advisory, asset management, property management and other similar fees. Such fees are earned pursuant to the advisory and property management agreements with the Managed REITs. The fees are recognized in the periods during which the related services are performed and the amounts have been contractually earned.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts
	Tenant accounts receivable are 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 at cost. 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 Personal Property Assets	Depreciation of Personal Property Assets
	Personal property assets, consisting primarily of furniture, fixtures and equipment 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 allocate a portion of the real estate purchase price of a property to in-place leases. We are amortizing in-place leases on a straight-line basis over the estimated future benefit period. As of December 31, 2014 and 2013, accumulated amortization of in-place lease intangibles totaled approximately $50.5 million and $44.6 million, respectively.
	The total estimated amortization expense of such intangible assets for the years ending December 31, 2015, 2016, 2017, 2018 and 2019 is approximately $3.8 million, $2.0 million, $0.2 million, none and none, respectively.
	In connection with the Self Administration and Investment Management Transaction, we allocated a portion of the consideration to the contracts that we acquired to manage the Managed REITs. We are amortizing certain amounts on a straight-line basis over the estimated benefit period of those contracts. As of December 31, 2014, the gross amount allocated to the contracts was $5.3 million and the accumulated amortization was approximately $0.2 million. The total estimated amortization expense for such intangible assets for the years ending December 31, 2015, 2016, 2017, 2018 and 2019 is approximately $0.5 million, $0.5 million, $0.5 million, $0.5 million, and $0.3 million, respectively. Approximately $2.7 million of value related to the management contracts was derived from cash flows we expect to be collected and subsequently paid to SSH, pursuant to the Acquisition Fee Tail Agreement. Such cash flows, if received, will reduce the carrying value of the management contracts. As of December 31, 2014, approximately $0.4 million of such cash flows were received by us and reduced the carrying value of the contracts, but were not paid to SSH as the payout ratio (as defined) had not been achieved (See Note 3 for additional information).
Amortization of Deferred Financing Costs	Amortization of Deferred Financing Costs
	Costs incurred in connection with obtaining financing are deferred and 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, 2014 and 2013, accumulated amortization of deferred financing costs totaled approximately $7.3 million and $5.9 million, respectively.
Organization and Offering Costs	Organization and Offering Costs
	Pursuant to our Former Advisory Agreement, our Former Advisor funded organization and offering costs on our behalf. We were required to reimburse our Former Advisor for such organization and offering costs; provided, however, our Former 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 and dealer manager fees) in excess of 3.5% of the gross offering proceeds from the Primary Offering. Such costs were recognized as a liability when we had a present responsibility to reimburse our Former Advisor, which was defined in our Former Advisory Agreement as the date we satisfied the minimum offering requirements of the primary offering portion of our Initial Offering (which occurred on May 22, 2008). If we had determined that the total organization and offering costs had exceeded 3.5% of the gross proceeds to be received from the Primary Offering, we would have recognized such excess as a capital contribution from our Former Advisor. Subsequent to the termination of our Offering on September 22, 2013, we have determined that organization and offering costs did not exceed 3.5% of the gross proceeds from the Primary Offering. Offering costs are recorded as an offset to additional paid-in capital, and organization costs are recorded as an expense.
Redeemable Common Stock	Redeemable Common Stock
	We previously had a share redemption program that enabled stockholders to sell their shares to us in limited circumstances.
	We recorded amounts that were redeemable under the share redemption program as redeemable common stock in the accompanying consolidated balance sheets since the shares were mandatorily redeemable at the option of the holder and therefore their redemption was outside our control. The maximum amount redeemable under our share redemption program was limited to the number of shares we could 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 but that are contingent on an event that is likely to occur (e.g., the passage of time) should be presented as redeemable when such amount is known. Therefore, the net proceeds from the distribution reinvestment plan were considered to be temporary equity and were presented as redeemable common stock in the accompanying consolidated balance sheets accordingly.
	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 were contingently redeemable at the option of the holder. When we determined we had a mandatory obligation to repurchase shares under the share redemption program, we reclassified such obligations from temporary equity to a liability based upon their respective settlement values.
	We funded all redemptions using proceeds from the sale of shares pursuant to our distribution reinvestment plan.
	In anticipation of a future possible liquidity event, on November 1, 2013, our board of directors approved the termination of our share redemption program, effective December 1, 2013.
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). For the years ended December 31, 2014, 2013 and 2012, we recorded a loss of approximately $1,065,000, a loss of approximately $460,000, and a gain of approximately $60,000, respectively.
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 to be recognized over the relevant service period.
Fair Value Measurements	Fair Value Measurements
	The accounting standard for fair value measurements and disclosures defines fair value, establishes a framework for measuring fair value, and provides for expanded disclosure about fair value measurements. Fair value is defined by the accounting standard for fair value measurements and disclosures as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. It also establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels. The following summarizes the three levels of inputs and hierarchy of fair value we use when measuring fair value:
		•		Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access;
		•		Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as interest rates and yield curves that are observable at commonly quoted intervals; and
		•		Level 3 inputs are unobservable inputs for the assets or liabilities that are typically based on an entity’s own assumptions as there is little, if any, related market activity.
	In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the fair value measurement will fall within the lowest level that is significant to the fair value measurement in its entirety.
	The accounting guidance for fair value measurements and disclosures provides a framework for measuring fair value and establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. In determining fair value, we 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 is 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 present herein are 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 assets and investments in unconsolidated joint ventures and related liabilities assumed and equity consideration related to our acquisitions. The fair values of these assets, liabilities and equity consideration 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, liabilities and equity consideration as of the acquisition dates were derived using Level 3 inputs.
	The carrying amounts of cash and cash equivalents, customer accounts receivable, other assets, accounts payable and accrued liabilities, distributions payable and amounts due to affiliates approximate fair value because of the relatively short-term nature of these instruments.
	The table below summarizes our fixed rate notes payable at December 31, 2014 and 2013. 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, which amounts were derived using Level 3 inputs. Accordingly, the estimates presented below are not necessarily indicative of the amounts we would realize in a current market exchange.
			December 31, 2014				December 31, 2013
			Fair Value		Carrying Value		Fair Value		Carrying Value
	Fixed Rate Secured Debt		$	303,295,393	$	287,655,570	$	311,362,132	$	300,894,201
	Through December 24, 2014, we had an interest rate swap on one of our loans (See Notes 6 and 7). The valuation of this instrument was 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 derivatives, including the period to maturity, and used observable market-based inputs, including interest rate curves and implied volatilities. The fair values of interest rate swaps were determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts were based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. To comply with GAAP, we incorporated 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 our derivative contracts for the effect of nonperformance risk, we considered 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 24, 2014, we had assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and had determined that the credit valuation adjustments were not significant to the overall valuation of our derivatives. As a result, we had determined that our derivative valuations in their entirety were classified in Level 2 of the fair value hierarchy. As of December 31, 2013, through December 24, 2014, we had Level 2 derivatives (interest rate swap) classified in accounts payable and accrued liabilities on our consolidated balance sheet.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities
	The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected future cash flows or other types of forecasted transactions are considered cash flow hedges.
	For derivatives designated as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in the consolidated statements of operations. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income, outside of earnings and subsequently reclassified to earnings when the hedged transaction affects earnings.
Noncontrolling Interest in Consolidated Entities	Noncontrolling Interest in Consolidated Entities
	We account for the noncontrolling interest in our Operating Partnership in accordance with amended accounting guidance. Due to our control through our general partnership interest in our Operating Partnership and the limited rights of the limited partners, our Operating Partnership, including its wholly-owned subsidiaries, is consolidated with the Company and the limited partner interest is reflected as a noncontrolling interest in the accompanying consolidated balance sheets. In addition, we account for the noncontrolling interest in the SF Property and the SSGT and SST II advisor entities in accordance with the amended accounting guidance. The noncontrolling interests shall continue to be attributed their share of income and losses, even if that attribution results in a deficit noncontrolling interest balance.
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, 2008. To qualify as a REIT, we must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of the REIT’s ordinary taxable income to stockholders. 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 will be 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. We have concluded that there are no significant uncertain tax positions requiring recognition or disclosure in our consolidated financial statements.
	Even if we 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 have filed an election to treat the TRSs as taxable REIT subsidiaries. In general, the TRSs may perform additional services for our customers and generally may engage in any real estate or non-real estate related business. The TRSs are subject to corporate federal and state income tax. The TRSs follow accounting guidance which requires the use of the asset and liability method. Deferred income taxes will 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 SmartStop Self Storage, Inc. for all periods presented are computed by dividing net income (loss) attributable to SmartStop Self Storage, Inc. by the weighted average number of shares outstanding during the period, excluding unvested restricted stock. Diluted earnings per share are computed by dividing net income (loss) attributable to SmartStop Self Storage, Inc. by the weighted average number of shares outstanding, adjusted for the dilutive effect of unvested restricted stock, utilizing the treasury stock method. For both of the years ended December 31, 2013 and 2012, 6,250 shares of unvested restricted stock were not included in the diluted weighted average shares calculation, as such shares were antidilutive.
Recently Issued Accounting Guidance	Recently Issued Accounting Guidance
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09 “Revenue from Contracts with Customers” (“ASU 2014-09”) as Accounting Standards Codification (“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. This ASU is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2016 and shall be applied using either a full retrospective or modified retrospective approach. Early adoption is not permitted. We are in the process of evaluating the impact of this standard on our consolidated financial statements and the impact is unknown at this time.
	In April 2014, the FASB issued ASU No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of an Entity”. Under the new guidance, only disposals representing a strategic shift, such as a major line of business, a major geographical area or a major equity investment, should be presented as discontinued operations. The guidance will be applied prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. The guidance is effective for annual financial statements with fiscal years beginning on or after December 15, 2014 with early adoption permitted for disposals or classifications as held for sale which have not been reported in financial statements previously issued or available for issuance. We will adopt the guidance effective January 1, 2015. We are in the process of evaluating the impact of this standard on our consolidated financial statements and the impact is unknown at this time.
	In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” ASU 2014-15 requires management to evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern, and to provide certain disclosures when it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued. ASU 2014-15 is effective for the annual period ended December 31, 2016 and for annual periods and interim periods thereafter with early adoption permitted. We are in the process of evaluating the impact of this standard on our consolidated financial statements and the impact is unknown at this time.
	In February 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis.” ASU 2015-02 changes the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. Specifically, ASU 2015-02 modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities, eliminates the presumption that a general partner should consolidate a limited partnership, and affects the evaluation of fee arrangements in the primary beneficiary determination. ASU 2015-02 is effective for periods beginning after December 15, 2015 and early adoption is permitted. We are in the process of evaluating the impact of this standard on our consolidated financial statements and the impact is unknown at this time.
Trademark
Goodwill and Trademark Valuation	Trademarks
	Trademarks are based on the value of our brands. Trademarks are valued using the relief from royalty method, which presumes that without ownership of such trademarks, we would have to make a stream of payments to a brand or franchise owner in return for the right to use their name. By virtue of this asset, we avoid any such payments and record the related intangible value of our ownership of the brand name. We used the following significant projections and assumptions to determine value under the relief from royalty method: revenues; royalty rate; tax expense; terminal growth rate; and discount rate. For the SmartStop® trademark, the projections underlying this relief from royalty model were forecasted for eight years and then a terminal value calculation was applied. For the Strategic Storage® trademark, the projections underlying the relief from royalty model were forecasted for six years. Applying the selected pretax royalty rates to the applicable revenue base in each period yielded pretax income for each of our trademarks. These pretax totals were tax effected utilizing the applicable tax rate to arrive at net, after-tax cash flows. The net, after-tax flows were then discounted to present value utilizing an appropriate discount rate. The present value of the after-tax cash flows were then added to the present value of the amortization tax benefit (considering the 15-year amortization of intangible assets pursuant to U.S. tax legislation) to arrive at the recommended fair values for the trademarks.
	We will evaluate whether any triggering events or changes in circumstances have occurred subsequent to our annual impairment test that would indicate an impairment condition may exist. If any change in circumstance or triggering event occurs, and results in a significant impact to our revenue and profitability projections, or any significant assumption in our valuations methods is adversely impacted, the impact could result in a material impairment charge in the future.
	In connection with the Self Administration and Investment Management Transaction, we recorded $11.5 million associated with the two primary trademarks acquired. Prior thereto we had no amounts recorded related to trademarks.
	Approximately $10.9 million of the original $11.5 million of trademarks relates to the “SmartStop®” trademark, which is an indefinite-lived intangible. The remaining approximately $0.6 million relates to our “Strategic Storage®” trademark and will be amortized over a five year period. As of December 31, 2014 we had accumulated amortization of $40,000 associated with the “Strategic Storage®” trademark.
	The total estimated amortization expense of the “Strategic Storage®” trademark asset for the years ending December 31, 2015, 2016, 2017, 2018 and 2019 is approximately $120,000, $120,000, $120,000, $120,000, and $80,000, respectively.
Goodwill
Goodwill and Trademark Valuation	Goodwill Valuation
	We have recorded goodwill of approximately $12.7 million as a result of the Self Administration and Investment Management Transaction. Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible assets and other intangible assets acquired. Goodwill is allocated to various reporting units, as applicable and is not amortized. We will perform an annual impairment test for goodwill and between annual tests, we will evaluate the recoverability of goodwill whenever events or changes in circumstances indicate that the carrying amount of goodwill may not be fully recoverable. In our impairment tests of goodwill, we will first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If based on this assessment, management determines that the fair value of the reporting unit is not less than its carrying amount, then performing the additional two-step impairment test is unnecessary. If the carrying amount of goodwill exceeds its fair value, an impairment charge will be recognized.
