Accounting Policies [Abstract]
Organization	Note 1. Organization Strategic Storage Trust II, Inc., a Maryland corporation (the “Company”), was formed on January 8, 2013 under the Maryland General Corporation Law for the purpose of engaging in the business of investing in self storage facilities. The Company’s year-end is December 31. As used in this report, “we,” “us,” “our,” and “Company” refer to Strategic Storage Trust II, Inc. Strategic Storage Holdings, LLC, a Delaware limited liability company (our “Prior Sponsor”), was the sponsor of our Offering (as defined below) through August 31, 2014. Effective August 31, 2014, SmartStop Self Storage, Inc. (“SmartStop”) entered into a series of transactions, agreements and amendments to its existing agreements and arrangements (such agreements and amendments hereinafter referred to collectively as the “Self Administration and Investment Management Transaction”) with our Prior Sponsor and its affiliates, pursuant to which, effective August 31, 2014, SmartStop became our sponsor and acquired the self storage advisory, asset management, property management and investment management businesses of our Prior Sponsor including our Prior Sponsor’s sole membership interest in SmartStop Asset Management, LLC, a Delaware limited liability company (“SmartStop Asset Management”), formerly known as Strategic Storage Realty Group, LLC, which owns 97.5% of the economic interests (and 100% of the voting membership interests) of Strategic Storage Trust Advisor II, LLC (our “Advisor”) and owns 100% of Strategic Storage Property Management II, LLC (our “Property Manager”). SmartStop was formed on August 14, 2007 for the purpose of engaging in the business of investing in self storage facilities. As of September 30, 2015, SmartStop owned 127 self storage facilities located in 17 states and the Greater Toronto Area. On October 1, 2015, SmartStop and Extra Space Storage Inc. (“Extra Space”), along with subsidiaries of each of SmartStop and Extra Space, closed on a merger transaction (the “Merger”) in which SmartStop was acquired by Extra Space for $13.75 per share in cash, representing an enterprise value of approximately $1.4 billion. At the closing of the Merger, SmartStop Asset Management, the owner of our Property Manager and majority and sole voting member of our Advisor, was sold to an entity controlled by H. Michael Schwartz, our Chairman of the Board of Directors, Chief Executive Officer and President, and became our sponsor (our “New Sponsor”). The former executive management team of SmartStop continues to serve as the executive management team for our New Sponsor. In addition, our management team remains the same, as well as the management team of our Advisor and Property Manager. At the closing of the Merger, we entered into new property management agreements with our Property Manager and our Property Manager entered into sub-property management agreements with Extra Space for the management of our properties. Furthermore, Extra Space acquired the rights to the “SmartStop ® ® Our Advisor, a Delaware limited liability company, was formed on January 8, 2013. Our Advisor is responsible for managing our affairs on a day-to-day basis and identifying and making acquisitions and investments on our behalf under the terms of the advisory agreement we have with our Advisor (our “Advisory Agreement”). The officers of our Advisor are also officers of us and our New Sponsor. On August 2, 2013, our Advisor purchased 100 shares of our common stock for $1,000 and became our initial stockholder. Our Articles of Amendment and Restatement authorizes 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. We are offering a maximum of $1,000,000,000 of common shares for sale to the public (the “Primary Offering”) and $95,000,000 of common shares pursuant to our distribution reinvestment plan (collectively the “Offering”). On January 10, 2014, the Securities and Exchange Commission (“SEC”) declared our registration statement effective. On May 23, 2014, we satisfied the $1.5 million minimum offering requirements of our Offering and commenced formal operations. On September 28, 2015, the Company revised its Offering of up to $1.095 billion in shares of common stock, including $95 million of shares offered under the Company’s distribution reinvestment plan. The Company is now offering two classes of shares of common stock: Class A common stock, $0.001 par value per share (the “Class A Shares”) and Class T common stock, $0.001 par value per share (the “Class T Shares”). As of September 30, 2015, we had issued approximately 5.7 million Class A Shares and no Class T Shares for gross proceeds of approximately $57.0 million and none, respectively. We intend to invest the net proceeds from the Offering primarily in self storage facilities and related self storage real estate investments. As of September 30, 2015, we owned 32 self storage properties located in ten states. Our operating partnership, Strategic Storage Operating Partnership II, L.P., a Delaware limited partnership (our “Operating Partnership”), was formed on January 9, 2013. During 2013, our Advisor purchased limited partnership interests in our Operating Partnership for $200,000 and on August 2, 2013, we contributed the initial $1,000 capital contribution we received to our Operating Partnership in exchange for the general partner interest. Our Operating Partnership owns, directly or indirectly through one or more special purpose entities, all of the self storage properties that we have acquired and the self storage properties we will acquire in the future. As of September 30, 2015, we owned approximately 99.6% of the common units of limited partnership interests of our Operating Partnership. The remaining approximately 0.4% of the common units are owned by our Advisor. As the sole general partner of our Operating Partnership, we have the exclusive power to manage and conduct the business of our Operating Partnership. We conduct certain activities through our taxable REIT subsidiary, Strategic Storage TRS II, Inc., a Delaware corporation (the “TRS”) which is a wholly-owned subsidiary of our Operating Partnership. Our Property Manager was formed on January 8, 2013 to manage our properties. Our Property Manager derives substantially all of its income from the property management services it performs for us. Our Property Manager may enter into sub-property management agreements with third party management companies and pay part of its management fee to such sub-property manager. Our dealer manager is Select Capital Corporation, a California corporation (our “Dealer Manager”). Our Dealer Manager is responsible for marketing our shares being offered pursuant to our Primary Offering. Our President and CEO owned, through a wholly-owned limited liability company, a 15% non-voting equity interest in our Dealer Manager through August 31, 2014. Effective August 31, 2014, pursuant to the Self Administration and Investment Management Transaction, SmartStop indirectly owned the 15% non-voting equity interest in our Dealer Manager. Effective October 1, 2015, in connection with the Merger, the 15% non-voting equity interest in our Dealer Manager is now owned by SmartStop Asset Management, our New Sponsor. An affiliate of our Dealer Manager continues to own a 2.5% non-voting membership interest in our Advisor. As we accept subscriptions for shares of our common stock, we transfer substantially all of the net offering proceeds to our Operating Partnership as capital contributions in exchange for additional units of interest in our Operating Partnership. However, we are deemed to have made capital contributions in the amount of gross proceeds received from investors, and our Operating Partnership is deemed to have simultaneously paid the sales commissions and other costs associated with the Offering. In addition, our Operating Partnership is structured to make distributions with respect to limited partnership units that are equivalent to the distributions made to holders of common stock. Finally, a limited partner in our Operating Partnership may later exchange his or her limited partnership units in our Operating Partnership for shares of our common stock at any time after one year following the date of issuance of their limited partnership units, subject to certain restrictions outlined in our Operating Partnership’s limited partnership agreement (the “Operating Partnership Agreement”). Our Advisor is prohibited from exchanging or otherwise transferring its limited partnership units so long as it is acting as our Advisor pursuant to our Advisory Agreement.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) as contained within the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and the rules and regulations of the Securities and Exchange Commission (“SEC”). Principles of Consolidation Our financial statements, and the financial statements of our Operating Partnership, including its wholly-owned subsidiaries, are consolidated in the accompanying consolidated financial statements. The portion of these entities not wholly-owned by us is presented as noncontrolling interests. All significant intercompany accounts and transactions have been eliminated in consolidation. Consolidation Considerations Current accounting guidance provides a framework for identifying a variable interest entity (“VIE”) and determining when a company should include the assets, liabilities, noncontrolling interests, and results of activities of a VIE in its consolidated financial statements. In general, a VIE is an entity or other legal structure used to conduct activities or hold assets that either (1) has an insufficient amount of equity to carry out its principal activities without additional subordinated financial support, (2) has a group of equity owners that are unable to make significant decisions about its activities, or (3) has a group of equity owners that do not have the obligation to absorb losses or the right to receive returns generated by its operations. Generally, a VIE should be consolidated if a party with an ownership, contractual, or other financial interest in the VIE (a variable interest holder) has the power to direct the VIE’s most significant activities and the obligation to absorb losses or right to receive benefits of the VIE that could be significant to the VIE. A variable interest holder that consolidates the VIE is called the primary beneficiary. Upon consolidation, the primary beneficiary generally must initially record all of the VIE’s assets, liabilities, and noncontrolling interest at fair value and subsequently account for the VIE as if it were consolidated based on majority voting interest. As of September 30, 2015 and December 31, 2014, we had not entered into contracts/interests that would be deemed to be variable interests in VIEs. 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 will adjust 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 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 will be mitigated by only investing in or through major financial institutions. Restricted Cash Restricted cash consists primarily of impound reserve accounts for property taxes, insurance and capital improvements in connection with the requirements of one of our loan agreements. Real Estate Purchase Price Allocation We account for acquisitions in accordance with amended 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. We also consider whether in-place, market leases represent an intangible asset. We preliminarily recorded approximately $13.9 million in intangible assets to recognize the value of in-place leases related to our acquisitions during 2015. We do not expect, nor to date have we recorded, intangible assets for the value of customer relationships because we expect we will not have concentrations of significant customers and the average customer turnover will be fairly frequent. Our acquisition-related transaction costs are required to be expensed as incurred. During both the three months ended September 30, 2015 and 2014, we expensed approximately $0.3 million of acquisition-related transaction costs. During the nine months ended September 30, 2015 and 2014, we expensed approximately $3.1 million and $0.7 million of acquisition-related transaction costs, respectively. Should the initial accounting for an acquisition be incomplete by the end of a reporting period that falls within the measurement period, we will report provisional amounts in our financial statements. During the measurement period, we will adjust the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date and we will record those adjustments to our financial statements. 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 may not be recoverable. When indicators of potential impairment are present that indicate that the carrying amounts of the assets may not be recoverable, we will assess the recoverability of the assets by determining whether the carrying value of the long-lived assets will be recovered through the undiscounted future operating cash flows expected from the use of the asset and its eventual disposition. In the event that such expected undiscounted future cash flows do not exceed the carrying value, we will adjust the value of the long-lived assets to the fair value and recognize an impairment loss. For the nine months ended September 30, 2015 and 2014, no impairment losses were recognized. Equity Investments Investments in unconsolidated real estate joint ventures and VIEs in which we are not the primary beneficiary, where we have significant influence, but not control, will be recorded under the equity method of accounting in our consolidated financial statements. Under the equity method, our investments in real estate ventures will be stated at cost and adjusted for our share of net earnings or losses and reduced by distributions. Equity in earnings of real estate ventures will be 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 minority interests will be accounted for under the cost method. Under the cost method, our investments in real estate ventures will be carried at cost and adjusted for other-than-temporary declines in fair value, distributions representing a return of capital and additional investments. Revenue Recognition Management believes that all of our leases are operating leases. Rental income is recognized in accordance with the terms of the leases, which generally are month-to-month. Revenues from any long-term operating leases are recognized on a straight-line basis over the term of the lease. The excess of rents received over amounts contractually due pursuant to the underlying leases is included in accounts payable and accrued liabilities in our consolidated balance sheets and contractually due but unpaid rent is included in other assets. Allowance for Doubtful Accounts Tenant accounts receivable, which is included in other assets in the accompanying consolidated balance sheets, is reported net of an allowance for doubtful accounts. Management’s estimate of the allowance is based upon a review of the current status of tenant accounts receivable. It is reasonably possible that management’s estimate of the allowance will change in the future. Real Estate Facilities Real estate facilities are recorded 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 30-35 years Site Improvements 7-10 years As described in Note 1, after the close of the Merger all of our properties are being re-branded under the Extra Space name. As such, during the three months ended September 30, 2015, the depreciable lives for capitalized SmartStop branded signs were reduced to their estimated remaining useful lives. Depreciation expense for the three months ended September 30, 2015 includes approximately $230,000 of accelerated depreciation related to the SmartStop branded signs. Depreciation of Personal Property Assets Personal property assets consist primarily of furniture, fixtures and equipment and are depreciated on a straight-line basis over the estimated useful lives generally ranging from 3 to 5 years, and are included in other assets on our consolidated balance sheets. Intangible Assets We have allocated a portion of our real estate purchase price to in-place leases. We are amortizing in-place leases on a straight-line basis over the estimated future benefit period. As of September 30, 2015 and December 31, 2014, the gross amounts allocated to in-place lease intangibles was approximately $16.1 million and $2.2 million respectively, and accumulated amortization of in-place lease intangibles totaled approximately $4.4 million and $0.2 million, respectively. 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 September 30, 2015 and December 31, 2014, accumulated amortization of deferred financing costs totaled approximately $0.4 million and $4,000, respectively. Organizational and Offering Costs Our Advisor may fund organization and offering costs on our behalf. We will be required to reimburse our Advisor for such organization and offering costs; provided, however, our Advisor must reimburse us within 60 days after the end of the month in 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. Such costs will be recognized as a liability when we have a present responsibility to reimburse our Advisor, which is defined in our Advisory Agreement as the date we satisfied the minimum offering requirements of our Offering (which occurred on May 23, 2014). If at any point in time we determine that the total organization and offering costs are expected to exceed 3.5% of the gross proceeds anticipated to be received from the Primary Offering, we will recognize such excess as a capital contribution from our Advisor. As of September 30, 2015, we do not believe total organization and offering costs will exceed 3.5% of the gross proceeds anticipated to be received 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 adopted a share redemption program that will enable stockholders to sell their shares to us in limited circumstances. We record amounts that are redeemable under the share redemption program as redeemable common stock in the accompanying consolidated balance sheet since the shares are redeemable at the option of the holder and therefore their redemption is outside our control. The maximum amount redeemable under our share redemption program is limited to the number of shares we can repurchase with the amount of the net proceeds from the sale of shares under the distribution reinvestment plan. However, accounting guidance states that determinable amounts that can become redeemable 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 are considered to be temporary equity and are presented as redeemable common stock in the accompanying consolidated balance sheets. In addition, current accounting guidance requires, among other things, that financial instruments that represent a mandatory obligation for us to repurchase shares be classified as liabilities and reported at settlement value. Our redeemable common shares will be contingently redeemable at the option of the holder. When we determine we have a mandatory obligation to repurchase shares under the share redemption program, we will reclassify such obligations from temporary equity to a liability based upon their respective settlement values. Through September 30, 2015 we received one request for the redemption of 1,750 shares which was fulfilled in July 2015. Accounting for Equity Awards The cost of restricted stock is required to be measured based on the grant date fair value and the cost recognized over the relevant service period. Fair Value Measurements 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 will use when measuring fair value: • Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access; • Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as interest rates and yield curves that are observable at commonly quoted intervals; and • Level 3 inputs are unobservable inputs for the assets or liabilities that are typically based on an entity’s own assumptions as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the fair value measurement will fall within the lowest level that is significant to the fair value measurement in its entirety. The accounting guidance for fair value measurements and disclosures provides a framework for measuring fair value and establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. In determining fair value, we will utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as consider counterparty credit risk in our assessment of fair value. Considerable judgment will be necessary to interpret Level 2 and 3 inputs in determining fair value of our financial and non-financial assets and liabilities. Accordingly, there can be no assurance that the fair values we will present will be indicative of amounts that may ultimately be realized upon sale or other disposition of these assets. Financial and non-financial assets and liabilities measured at fair value on a non-recurring basis in our consolidated financial statements consist of real estate and related liabilities assumed related to our acquisitions. The fair values of these assets and liabilities were determined as of the acquisition dates using widely accepted valuation techniques, including (i) discounted cash flow analysis, which considers, among other things, leasing assumptions, growth rates, discount rates and terminal capitalization rates, (ii) income capitalization approach, which considers prevailing market capitalization rates, and (iii) comparable sales activity. In general, we consider multiple valuation techniques when measuring fair values. However, in certain circumstances, a single valuation technique may be appropriate. All of the fair values of the assets and liabilities as of the acquisition dates were derived using Level 3 inputs. The carrying amounts of cash and cash equivalents, other assets, accounts payable and accrued liabilities, distributions payable and amounts due to affiliates will approximate fair value because of the relatively short-term nature of these instruments. The table below summarizes our fixed rate notes payable at September 30, 2015 and December 31, 2014. The estimated fair value of financial instruments is subjective in nature and is dependent on a number of important assumptions, including discount rates and relevant comparable market information associated with each financial instrument. The fair value of the fixed rate notes payable was estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. The use of different market assumptions and estimation methodologies may have a material effect on the reported estimated fair value amounts. Accordingly, the estimates presented below are not necessarily indicative of the amounts we would realize in a current market exchange. September 30, 2015 December 31, 2014 Fair Value Carrying Value Fair Value Carrying Value Fixed Rate Secured Debt $ 13,560,000 $ 13,305,056 $ 13,500,000 $ 13,494,871 To comply with GAAP, we incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of derivative contracts for the effect of non-performance risk, we will consider the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. Noncontrolling Interest in Consolidated Entities We account for the noncontrolling interest in our Operating Partnership in accordance with the related accounting guidance. Due to our control through our general partnership interest in our Operating Partnership and the limited rights of the limited partner, our Operating Partnership, including its wholly-owned subsidiaries, are consolidated with the Company and the limited partner interest is reflected as a noncontrolling interest in the accompanying consolidated balance sheet. The noncontrolling interest shall be attributed its 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, 2014. To qualify as a REIT, we must continue to meet certain organizational and operational requirements, including a requirement to distribute at least 90% of the REIT’s ordinary taxable income to stockholders. 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. 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 filed elections to treat our TRS as a taxable REIT subsidiary effective January 1, 2014. In general, the TRS performs additional services for our customers and generally engages in any real estate or non-real estate related business. The TRS is subject to corporate federal and state income tax. The TRS follows accounting guidance which requires the use of the asset and liability method. Deferred income taxes represent the tax effect of future differences between the book and tax bases of assets and liabilities. Per Share Data Basic earnings per share attributable for all periods presented are computed by dividing net income (loss) by the weighted average number of shares outstanding during the period. Diluted earnings per share are computed by dividing net income (loss) by the weighted average number of shares outstanding, including all restricted stock grants as though fully vested. For the three and nine months ended September 30, 2015, and 2014, 7,500 Class A Shares, and none, respectively, of unvested restricted stock were not included in diluted weighted average shares as such common 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. In July 2015, the FASB voted to defer the effective date by one year to annual reporting periods (including interim periods within those periods) beginning after December 15, 2017 and early adoption is permitted. This ASU shall still be applied using either a full retrospective or modified retrospective approach. 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. In April 2015, the FASB issued ASU 2015-03, “Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. ASU 2015-03 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. In September 2015, the FASB issued ASU 2015-16, “Business Combinations: Simplifying the Accounting for Measurement-Period Adjustments”. ASU 2015-16 requires an acquirer in a business combination to recognize adjustments to estimated amounts identified during the measurement period in the reporting period in which the adjustment amounts are determined. The acquirer must record the effect of the adjustments on earnings as if the accounting had been completed at the acquisition date and the acquirer must disclose in its financial statements the portion of the amounts recorded in each line item of current-period earnings that would have been recorded in previous periods if the adjustments to estimated amounts had been recognized as of the acquisition date. The update is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years, with early adoption permitted for financial statements that have not been issued. 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.

Real Estate Facilities	Note 3. Real Estate Facilities The following summarizes the activity in real estate facilities during the nine months ended September 30, 2015: Real estate facilities Balance at December 31, 2014 $ 20,857,880 Facility acquisitions 123,493,750 Improvements and additions 1,858,244 Balance at September 30, 2015 $ 146,209,874 Accumulated depreciation Balance at December 31, 2014 $ (93,433 ) Depreciation expense (2,691,124 ) Balance at September 30, 2015 $ (2,784,557 ) On August 14, 2014, the Company, through 26 wholly-owned subsidiaries of our Operating Partnership, executed 26 partial assignments of the purchase and sale agreement originally executed by a subsidiary of our Prior Sponsor on July 9, 2014, with unaffiliated third parties for the acquisition of 14 self storage facilities located in California; four self storage facilities located in Michigan; three self storage facilities located in Colorado; two self storage facilities located in Illinois and one self storage facility located in each of New Jersey, Washington and Maryland (the “26 Property Portfolio”). On January 23, 2015, we closed on seven self storage facilities located in California, Colorado, Illinois and Maryland representing the first phase of the acquisition of the 26 Property Portfolio for a purchase price of $26.3 million, plus closing costs and acquisition fees. On January 29, 2015, we closed on five self storage facilities located in California and Colorado representing the second phase of the acquisition of the 26 Property Portfolio for a purchase price of approximately $28.6 million, plus closing costs and acquisition fees. On February 5, 2015, we closed on seven self storage facilities located in California, Colorado and Washington representing the third phase of the acquisition of the 26 Property Portfolio for a purchase price of approximately $45.8 million, plus closing costs and acquisition fees. On February 19, 2015, we closed on two self storage facilities located in California and Illinois representing the fourth phase of the acquisition of the 26 Property Portfolio for a purchase price of approximately $10.9 million, plus closing costs and acquisition fees. On May 8, 2015, we closed on three self storage facilities located in Michigan representing the fifth phase of the acquisition of the 26 Property Portfolio for a purchase price of approximately $11.9 million, plus closing costs and acquisition fees. On May 21, 2015, we closed on the purchase of the sixth phase of the 26 Property Portfolio which consisted of one self storage facility located in Michigan for a purchase price of approximately $3.9 million, plus closing costs and acquisition fees. On May 28, 2015, we closed on one self storage facility located in New Jersey, representing the seventh and final phase of the acquisition of the 26 Property Portfolio for a purchase price of approximately $2.2 million, plus closing costs and acquisition fees. The Company funded the acquisitions of the 26 Property Portfolio with a combination of proceeds from draws under the KeyBank Facility (Note 5), issuance of preferred units in the Operating Partnership (Note 6), and proceeds from our Primary Offering. On September 11, 2015 we closed on a self storage facility located in Foley, Alabama for a purchase price of approximately $8.0 million, plus closing costs and acquisition fees. The Company funded the acquisition of the Foley property with proceeds from our Primary Offering.

Debt Disclosure [Abstract]
Secured Debt	Note 5. Secured Debt Raleigh/Myrtle Beach Promissory Note In connection with the acquisition of the five properties in November 2014 (collectively, the “Raleigh/Myrtle Beach Portfolio”), we, through five special purpose entities formed to acquire and hold the properties comprising the Raleigh/Myrtle Beach Portfolio (collectively, the “Raleigh/Myrtle Beach Borrowing Entities”), assumed a secured promissory note with C-III Commercial Mortgage LLC (“C-III”) dated August 30, 2013, in the amount of approximately $12,600,000 (the “Raleigh/Myrtle Beach Promissory Note”). The Raleigh/Myrtle Beach Promissory Note matures in September 2023 and carries a fixed interest rate of 5.73%. The Raleigh/Myrtle Beach Promissory Note has a prepayment lockout for the first two years of the note. After September 2015, we may defease the Raleigh/Myrtle Beach Promissory Note upon the occurrence of certain conditions. The Raleigh/Myrtle Beach Promissory Note is secured by deeds of trust on our interest in three of the properties in the Raleigh/Myrtle Beach Portfolio, a mortgage on our interest in the other two properties comprising the Raleigh/Myrtle Beach Portfolio and certain of the assets of the Raleigh/Myrtle Beach Borrowing Entities. In addition, we and SmartStop executed a guaranty in favor of C-III guaranteeing the payment of the Raleigh/Myrtle Beach Promissory Note (the “Raleigh/Myrtle Beach Guaranty”). Extra Space acquired SmartStop through the Merger on October 1, 2015, and as a result, an affiliate of Extra Space assumed SmartStop’s obligations under the guaranty. The Raleigh/Myrtle Beach Guaranty requires that we and the Extra Space affiliate, collectively, maintain a net worth of at least $6.0 million and an aggregate liquidity of at least $2.0 million, exclusive of the interest in the Raleigh/Myrtle Beach Portfolio. The Extra Space affiliate may be released from its obligations under the Raleigh/Myrtle Beach Guaranty if certain conditions are met, including that we alone satisfy the aforementioned net worth and liquidity requirements and that the preferred equity investment in our Operating Partnership is repaid in full. KeyBank Facility On January 20, 2015, we, through our Operating Partnership and certain affiliated entities, entered into a credit facility (the “KeyBank Facility”) with KeyBank, National Association (“KeyBank”), as administrative agent, KeyBanc Capital Markets, LLC, as sole book runner and sole lead arranger and Texas Capital Bank, N.A. (“Texas Capital”), as documentation agent. Under the terms of the KeyBank Facility, we may borrow up to approximately $71.3 million, of which KeyBank has committed up to approximately $46.3 million and Texas Capital has committed up to $25 million (KeyBank and Texas Capital are collectively, the “Lenders”). Each borrowing under the KeyBank Facility will be comprised of either Alternate Base Rate (“ABR”) Loans or Eurodollar Loans, as defined in the KeyBank Credit Agreement (as defined below), as we may request. We may elect to convert a borrowing to a different type or to continue a borrowing under the same type and, in the case of a Eurodollar Loan, may elect the applicable Interest Periods (as defined in the KeyBank Credit Agreement). The KeyBank Facility has an initial term of three years, maturing on January 20, 2018, with two one-year extension options subject to certain conditions outlined further in the credit agreement for the KeyBank Facility (the “KeyBank Credit Agreement”). Payments due pursuant to the KeyBank Facility are interest-only for the first 36 months and a 30-year amortization schedule thereafter. The KeyBank Facility bears interest based on the type of borrowing. The ABR Loans bear interest at the lesser of (i) the Alternate Base Rate (as defined in the KeyBank Credit Agreement) plus the Applicable Rate, or (ii) the Maximum Rate (as defined in the KeyBank Credit Agreement). The Eurodollar Loans bear interest at the lesser of (a) the Adjusted LIBO Rate (as defined in the KeyBank Credit Agreement) for the Interest Period in effect plus the Applicable Rate, or (b) the Maximum Rate (as defined in the KeyBank Credit Agreement). The Applicable Rate means for any Eurodollar Loan, 325 basis points, and for any ABR Loan, 225 basis points. The KeyBank Facility is fully recourse and is secured by cross-collateralized first mortgage liens on the Mortgaged Properties (as defined in the KeyBank Credit Agreement). The KeyBank Facility contains a cross-default provision in which an event of default will occur under the KeyBank Facility if we default under any other recourse debt until we have a tangible net worth equal to or greater than $100 million and then to any other recourse debt of $25 million or greater in the aggregate or non-recourse debt of $75 million or greater in the aggregate. The KeyBank Facility may be prepaid or terminated at any time without penalty, provided, however, that the Lenders shall be indemnified for any breakage costs. Pursuant to that certain guaranty, dated January 20, 2015, in favor of the Lenders, we serve as a guarantor of all obligations due under the KeyBank Facility. Under certain conditions, we may cause the release of one or more of the properties serving as collateral for the KeyBank Credit Facility, subject to no default or event of default is then outstanding or would reasonably occur as a result of such release, including compliance with the Loan to Value Ratio and the Debt-Service Coverage Ratio (each as defined in the KeyBank Credit Agreement), and we pay the applicable Release Price (as defined in the KeyBank Credit Agreement). Additionally, on May 21, 2015, our Operating Partnership purchased an interest rate cap with a notional amount of $50 million, such that in no event will our interest rate exceed 5.25% thereon through June 1, 2016. We borrowed approximately $71.3 million under the KeyBank Facility to fund a portion of the 26 Property Portfolio. The amounts drawn were in the form of a Eurodollar Loan under the KeyBank Credit Agreement which bear interest at approximately 3.45% as of September 30, 2015. We may change this election from time to time, as provided by the KeyBank Credit Agreement. Pursuant to joinder agreements by the special purpose entities wholly-owned by our Operating Partnership (the “Property SPEs”) in favor of KeyBank as administrative agent, the 26 properties acquired in the 26 Property Portfolio now serve as additional collateral under the KeyBank Credit Agreement and the Property SPEs now serve as additional borrowers.

Equity [Abstract]
Preferred Equity	Note 6. Preferred Equity Issuance of Preferred Units by our Operating Partnership On November 3, 2014, we and our Operating Partnership entered into a Series A Cumulative Redeemable Preferred Unit Purchase Agreement (the “Unit Purchase Agreement”) with SSTI Preferred Investor, LLC (the “Preferred Investor”), a wholly-owned subsidiary of SmartStop Self Storage Operating Partnership, L.P. through September 30, 2015, and a subsidiary of Extra Space effective October 1, 2015 as a result of the Merger. Pursuant to the Unit Purchase Agreement, the Preferred Investor agreed to provide up to $65 million through a preferred equity investment in our Operating Partnership (the “Preferred Equity Investment”), which amount may be invested in one or more tranches, to be used solely for investments in self storage properties, as described in the underlying documents, in exchange for up to 2.6 million preferred units of limited partnership interest of our Operating Partnership (the “Preferred Units”), each having a liquidation preference of $25.00 per Preferred Unit (the “Liquidation Amount”), plus all accumulated and unpaid distributions. In addition to the Unit Purchase Agreement, we and our Operating Partnership entered into a Second Amended and Restated Limited Partnership Agreement of the Operating Partnership (the “Second Amended and Restated Limited Partnership Agreement”) Amendment No. 1 to the Second Amended and Restated Limited Partnership Agreement (the “First Amendment”). The Second Amended and Restated Limited Partnership Agreement authorized the issuance of additional classes of units of limited partnership interest in the Operating Partnership, established a new series of preferred units of limited partnership interest in the Operating Partnership and sets forth other necessary corresponding changes. All other terms of the Second Amended and Restated Limited Partnership Agreement remained substantially the same as the original Limited Partnership Agreement. The First Amendment sets forth key terms of the Preferred Units, some of which are discussed below. On November 3, 2014, the Preferred Investor invested approximately $6.5 million in the first tranche of its Preferred Equity Investment in our Operating Partnership, of which (i) approximately $5.0 million was used to fund a portion of the Raleigh/Myrtle Beach Portfolio acquisition, and (ii) approximately $1.5 million was used to pay expenses incurred by the Preferred Investor in accordance with the Amendment. The Preferred Investor received approximately 260,000 Preferred Units in our Operating Partnership. On December 31, 2014, we issued approximately 1,020 Preferred Units in our Operating Partnership to the Preferred Investor to cover the approximately $25,000 in costs incurred by the Preferred Investor in making its investment. As of May 28, 2015 we had closed on all properties in the 26 Property Portfolio through seven phases of closings. The acquisitions were funded in part by the issuance of an aggregate of approximately 2.1 million Preferred Units in our Operating Partnership for approximately $53.0 million. On July 22, 2015 and September 23, 2015 we redeemed $6.0 million and $8.5 million in the Preferred Equity Investment, respectively. As of September 30, 2015, the Preferred Investor had an aggregate of approximately $45.0 million invested in our Operating Partnership, representing approximately 1.8 million Preferred Units in our Operating Partnership. The holders of the Preferred Units will receive current distributions (the “Current Distributions”) at a rate of a one-month LIBOR plus 6.5% per annum on the Liquidation Amount, payable monthly and calculated on an actual/360 basis. In addition to the Current Distributions, our Operating Partnership has the obligation to elect either (A) to pay the holder of the Preferred Units additional distributions monthly in an amount equal to: (i) 4.35% per annum of the Liquidation Amount through March 31, 2017; and (ii) beginning April 1, 2017, 6.35% per annum of the Liquidation Amount or (B) defer the additional distributions ( the “Deferred Distributions”) in an amount that will accumulate monthly in an amount equal to (i) LIBOR plus 10.85% of the Deferred Distributions through March 31, 2017; and (ii) beginning April 1, 2017, LIBOR plus 12.85% of the Deferred Distributions. The Preferred Units may be redeemed by our Operating Partnership, in whole or in part, at the option of our Operating Partnership at any time. The redemption price (the “Redemption Price”) for the Preferred Units will be equal to: (i) in the event of a partial redemption, the sum of the Liquidation Amount plus all accumulated and unpaid Current Distributions thereon to the date of redemption; and (ii) in the event of the redemption of all outstanding Preferred Units, the sum of the Liquidation Amount plus all accumulated and unpaid Current Distributions and any accumulated Deferred Distributions thereon to the date of redemption. If fewer than all of the outstanding Preferred Units are to be redeemed at the option of our Operating Partnership, the Preferred Units to be redeemed will be determined pro rata or by lot or in such other manner as determined by us, as the general partner of our Operating Partnership to be fair and equitable to all holders of the Preferred Units. The holder of the Preferred Units may require our Operating Partnership to repurchase the Preferred Units upon the occurrence of any of the following (each an “Optional Repurchase Event”) and as defined within the Amendment: (A) a breach of any of the Protective Provisions; (B) an Event of Default; (C) a Change of Control that has not been consented to in accordance with the terms of the Amendment; (D) our failure to qualify as a REIT under the Internal Revenue Code; or (E) the occurrence and continuance of a monetary or a material default beyond any applicable cure period under any of the loan documents for each of the properties in our portfolio. The repurchase price for the Preferred Units will be the Redemption Price.

Organization and Offering Costs Organization and offering costs of the Offering may be paid by our Advisor on our behalf and will be reimbursed to our Advisor from the proceeds of our Offering. Organization and offering costs consist 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 organization and offering expenses, including, but not limited to, (i) amounts to reimburse our Advisor for all marketing related costs and expenses such as salaries and direct expenses of employees of our Advisor and its affiliates in connection with registering and marketing our shares; (ii) technology costs associated with the Offering; (iii) our costs of conducting our training and education meetings; (iv) our costs of attending retail seminars conducted by participating broker-dealers; and (v) payment or reimbursement of bona fide due diligence expenses. Our Advisor must 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. Advisory Agreement We do not have any employees. Our Advisor is primarily responsible for managing our business affairs and carrying out the directives of our board of directors. Our Advisor receives various fees and expenses under the terms of our Advisory Agreement. We are required under our Advisory Agreement to reimburse our Advisor for organization and offering costs; provided, however, our Advisor is required to reimburse us within 60 days after the end of the month in 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. Our Advisory Agreement also requires our Advisor to reimburse us 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 Offering. Our Advisor receives acquisition fees equal to 1.75% of the contract purchase price of each property we acquire plus reimbursement of any acquisition expenses our Advisor incurs. Our Advisor also receives a monthly asset management fee equal to 0.05208%, which is one-twelfth of 0.625%, of our average invested assets, as defined. Under our Advisory Agreement, our Advisor receives disposition fees in an amount equal to the lesser of (i) one-half of the competitive real estate commission or (ii) 1% of the contract sale price for each property we sell, as long as our Advisor provides substantial assistance in connection with the sale. The total real estate commissions paid (including the disposition fee paid to our Advisor) may not exceed the lesser of a competitive real estate commission or an amount equal to 6% of the contract sale price of the property. Our Advisor is also entitled to various subordinated distributions pursuant to our Operating Partnership Agreement if we (1) list our shares of common stock on a national exchange, (2) terminate our Advisory Agreement (other than a voluntary termination), (3) liquidate our portfolio, or (4) enter into an Extraordinary Transaction, as defined in the Operating Partnership Agreement. Our Advisory Agreement provides for reimbursement of our Advisor’s direct and indirect costs of providing administrative and management services to us. Beginning four fiscal quarters after we acquire our first real estate asset, our Advisor is required to pay or reimburse us the amount by which our aggregate annual operating expenses, as defined, exceed the greater of 2% of our average invested assets or 25% of our net income, as defined, unless a majority of our independent directors determine that such excess expenses were justified based on unusual and non-recurring factors. For any fiscal quarter for which total operating expenses for the 12 months then ended exceed the limitation, we will disclose this fact in our next quarterly report or within 60 days of the end of that quarter and send a written disclosure of this fact to our stockholders. In each case the disclosure will include an explanation of the factors that the independent directors considered in arriving at the conclusion that the excess expenses were justified. Dealer Manager Agreement Our Dealer Manager receives a sales commission of up to 7.0% of gross proceeds from sales of Class A Shares and up to 2.0% of gross proceeds from the sales of Class T Shares in the Primary Offering and a dealer manager fee up to 3.0% of gross proceeds from sales of both Class A Shares and Class T Shares in the Primary Offering under the terms of our Dealer Manager Agreement. In addition, our Dealer Manager will receive an ongoing stockholder servicing fee that will be payable monthly and will accrue daily in an amount equal to 1/365 th Affiliated Dealer Manager Our Chief Executive Officer and President owned, through a wholly-owned limited liability company, a 15% non-voting equity interest in our Dealer Manager through August 31, 2014. Effective, August 31, 2014, pursuant to the Self Administration and Investment Management Transaction, SmartStop indirectly owned the 15% non-voting equity interest in our Dealer Manager. Effective October 1, 2015, in connection with the Merger, the 15% non-voting equity interest in our Dealer Manager is now owned by our New Sponsor. An affiliate of our Dealer Manager continues to own a 2.5% non-voting membership interest in our Advisor. Property Management Agreement Through September 30, 2015, each of our self storage properties was managed by our Property Manager under separate property management agreements. Under each agreement, our Property Manager received a fee for its services in managing our properties, generally equal to the greater of $3,000 or 6% of the gross revenues from the properties plus reimbursement of the Property Manager’s costs of managing the properties. Reimbursable costs and expenses include wages and salaries and other expenses of employees engaged in operating, managing and maintaining our properties. Our Property Manager also received a one-time fee for each property acquired by us that was managed by our Property Manager in the amount of $3,750. In the event that our Property Manager assisted with the development or redevelopment of a property, we paid a separate market-based fee for such services. In addition, our Property Manager was entitled to a construction management fee equal to 5% of the cost of construction or capital improvement work in excess of $10,000 and an administration fee equal to $0.50 a month for each insurance policy purchased by a tenant at one of our properties in connection with the tenant insurance program. Additionally, each agreement included a non-solicitation provision and a provision regarding the Property Manager’s use of trademarks and other intellectual property owned by SmartStop. As of October 1, 2015, each of our self storage properties are subject to separate property management agreements with our Property Manager, which in turn has entered into sub-property management agreements with Extra Space, which will provide on-site management of our properties. Under the property management agreements, our Property Manager receives a monthly management fee of $2,500 or 6% of the gross revenues, whichever is greater, plus reimbursement of the Property Manager’s costs of managing the properties. Extra Space has agreed to pay up to $25,000 for each property managed toward the signage and set-up costs associated with converting each property to the Extra Space brand (the “Set-Up Amount”). The property management agreements have a three year term and automatically renew for successive one year periods thereafter, unless we or our Property Manager provides prior written notice at least 90 days prior to the expiration of the term. We may terminate a property management agreement without cause at any time during the initial three year term if we pay the Property Manager a termination fee equal to the Set-Up Amount, reduced by 1/36 th The sub-property management agreements between our Property Manager and Extra Space are substantially the same as the property management agreements between us and our Property Manager. Under the sub-property management agreements, our Property Manager will pay Extra Space a monthly management fee of $2,500 or 6% of the gross revenues, whichever is greater, plus reimbursement of Extra Space’s costs of managing the properties; provided, however that no management fee is due and payable to Extra Space for the months of January and July each year during the term. Extra Space has the exclusive right to offer tenant insurance to the tenants and is entitled to all of the benefits of such tenant insurance. The sub-property management agreements also have a three year term and automatically renew for successive one year periods thereafter, unless our Property Manager or Extra Space provides prior written notice at least 90 days prior to the expiration of the term. Our Property Manager may terminate the sub-property management agreement without cause at any time during the initial three year term if it pays Extra Space a termination fee equal to the Set-Up Amount, reduced by 1/36 th In addition, we entered into an agreement with Extra Space and our Property Manager in which we agreed that, subject to certain limitations, our Property Manager will retain Extra Space as sub-property manager for all self storage properties we acquire in the United States that will be managed by our Property Manager. Pursuant to the terms of the agreements described above, the following table summarizes related party costs incurred and paid by us for the year ended December 31, 2014, and the nine months ended September 30, 2015, and any related amounts payable as of December 31, 2014 and September 30, 2015: Year Ended December 31, 2014 Nine Months Ended September 30, 2015 Incurred Paid Payable Incurred Paid Payable Expensed Operating expenses (including organizational costs) $ 862,827 $ 26,326 $ 836,501 $ 1,060,736 $ 1,848,986 $ 48,251 Asset management fees 22,254 — 22,254 616,858 639,112 — Property management fees 47,287 — 47,287 927,764 975,051 — Acquisition expenses 1,089,783 386,750 703,033 2,625,303 3,247,701 80,635 Capitalized Deferred financing costs 441,873 — 441,873 214,006 505,879 150,000 Other assets 461,492 — 461,492 77,556 539,048 — Additional Paid-in Capital Selling commissions 1,201,157 1,201,157 — 3,012,145 3,012,145 — Dealer Manager fee 514,781 508,902 5,879 753,037 729,339 29,577 Offering costs 1,805,916 — 1,805,916 319,882 2,069,699 56,099 Total $ 6,447,370 $ 2,123,135 $ 4,324,235 $ 9,607,287 $ 13,566,960 $ 364,562 Tenant Insurance Program Prior to the closing of the Merger on October 1, 2015, SmartStop participated in a tenant reinsurance program whereby customers of our self storage facilities were able to purchase insurance to cover damage or destruction to their property while stored at our facilities. SmartStop invested in a Cayman Islands company (the “Reinsurance Company”) that insures 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 provided fees (approximately 50% of the tenant premium paid) to us as owner of the facilities. The Reinsurance Company was required to fund additional capital or entitled to receive distributions of profits depending on actual losses incurred under the program. Commensurate with the effective date of the Self Administration and Investment Management Transaction of August 31, 2014, SmartStop acquired its interest in the Reinsurance Company from our Chief Executive Officer and President. For the three months ended September 30, 2015 and 2014, we recorded revenue of approximately $100,000 and none, respectively, from the program insurer. For the nine months ended September 30, 2015 and 2014, we recorded revenue of approximately $260,000 and none, respectively, from the program insurer. Effective October 1, 2015, Extra Space will be entitled to all tenant insurance revenues and we will no longer receive any such tenant insurance revenues. Storage Auction Program Our President and Chief Executive Officer, and our Senior Vice President — Property Management and the President of our Property Manager, own minority 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 will pay the Auction Company a service fee based upon the sale price of the unit. Collectively, these officers own 9% of the voting interests in the Auction Company. For the three months ended September 30, 2015 and 2014, we had incurred fees of approximately $2,000 and none, respectively, in connection with the Auction Company. For the nine months ended September 30, 2015 and 2014, we had incurred fees of approximately $5,000 and none, respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 8. Commitments and Contingencies Distribution Reinvestment Plan We have adopted an amended and restated distribution reinvestment plan that allows both our Class A and Class T stockholders to have distributions otherwise distributable to them invested in additional shares of our Class A and Class T Shares, respectively. The purchase price per share is 95% of the current offering price of our shares in the Primary Offering. We may amend or terminate the amended and restated distribution reinvestment plan for any reason at any time upon 10 days’ prior written notice to stockholders. As of September 30, 2015 we have sold approximately $0.6 million in shares through our distribution reinvestment plan offering. Share Redemption Program We adopted a share redemption program that enables stockholders to sell their shares to us in limited circumstances. As long as our common stock is not listed on a national securities exchange or over-the-counter market, our stockholders who have held their stock for at least one year may be able to have all or any portion of their shares of stock redeemed by us. We may redeem the shares of stock presented for redemption for cash to the extent that we have sufficient funds available to fund such redemption. Our board of directors may amend, suspend or terminate the share redemption program with 30 days’ notice to our stockholders. We may provide this notice by including such information in a Current Report on Form 8-K or in our annual or quarterly reports, all publicly filed with the SEC, or by a separate mailing to our stockholders. The complete terms of our share redemption program are described in our prospectus. The amount that we may pay to redeem stock for redemptions is the redemption price set forth in the following table which is based upon the number of years the stock is held: Number Years Held Redemption Price Less than 1 No Redemption Allowed 1 or more but less than 3 90.0% of Redemption Amount 3 or more but less than 4 95.0% of Redemption Amount 4 or more 100.0% of Redemption Amount At any time we are engaged in an offering of shares, the Redemption Amount for shares purchased under our share redemption program will always be equal to or lower than the applicable per share offering price. As long as we are engaged in an offering, the Redemption Amount shall be the lesser of the amount the stockholder paid for their shares or the price per share in the current offering. If we are no longer engaged in an offering, the per share Redemption Amount will be determined by our board of directors. Our board of directors will announce any redemption price adjustment and the time period of its effectiveness as a part of its regular communications with our stockholders. At any time the redemption price during an offering is determined by any method other than the offering price, if we have sold property and have made one or more special distributions to our stockholders of all or a portion of the net proceeds from such sales, the per share redemption price will be reduced by the net sale proceeds per share distributed to investors prior to the redemption date as a result of the sale of such property in the special distribution. Our board of directors will, in its sole discretion, determine which distributions, if any, constitute a special distribution. While our board of directors does not have specific criteria for determining a special distribution, we expect that a special distribution will only occur upon the sale of a property and the subsequent distribution of the net sale proceeds. There are several limitations on our ability to redeem shares under the share redemption program including, but not limited to: • Unless the shares are being redeemed in connection with a stockholder’s death, “qualifying disability” (as defined under the share redemption program) or bankruptcy, we may not redeem shares until the stockholder has held his or her shares for one year. • During any calendar year, we will not redeem in excess of 5% of the weighted-average number of shares outstanding during the prior calendar year. • The cash available for redemption is limited to the proceeds from the sale of shares pursuant to our distribution reinvestment plan. • We have no obligation to redeem shares if the redemption would violate the restrictions on distributions under Maryland law, which prohibits distributions that would cause a corporation to fail to meet statutory tests of solvency. Through September 30, 2015 we received one request for the redemption of 1,750 shares which was fulfilled in July 2015. Operating Partnership Redemption Rights The limited partners of our Operating Partnership have the right to cause our Operating Partnership to redeem their limited partnership units for cash equal to the value of an equivalent number of our shares, or, at our option, we may purchase their limited partnership units by issuing one share of our common stock for each limited partnership unit redeemed. These rights may not be exercised under certain circumstances that could cause us to lose our REIT election. Furthermore, limited partners may exercise their redemption rights only after their limited partnership units have been outstanding for one year. Our Advisor is prohibited from exchanging or otherwise transferring its limited partnership units so long as our Advisor is acting as our advisor under the Advisory Agreement. Other Contingencies From time to time, we are party to legal proceedings that arise in the ordinary course of our business. We are not aware of any legal proceedings of which the outcome is reasonably likely to have a material adverse effect on our results of operations or financial condition, nor are we aware of any such legal proceedings contemplated by governmental authorities.

The purchase price for the Boynton Beach Property is approximately $18 million, plus closing costs and acquisition fees. We expect the acquisition of the Boynton Beach Property to close in the fourth quarter of 2015 and to fund such acquisition with a combination of net proceeds from our Primary Offering and a credit facility or other debt financing. There can be no assurance that we will complete the acquisition. If we fail to acquire this property, in addition to incurred acquisition costs, we may also forfeit earnest money as a result. Potential Acquisition – Lancaster, California On November 12, 2015, one of our subsidiaries executed a purchase and sale agreement with an unaffiliated third party (the “Lancaster Purchase Agreement”) for the acquisition of a self storage facility (the “Lancaster Property”). The Lancaster Property is a single story property located in Lancaster, California. The purchase price for the Lancaster Property is approximately $4.7 million, plus closing costs and acquisition fees. We expect the acquisition of the Lancaster Property to close in the first quarter of 2016 and to fund such acquisition with a combination of net proceeds from our Primary Offering and a credit facility or other debt financing. There can be no assurance that we will complete the acquisition. If we fail to acquire this property, in addition to incurred acquisition costs, we may also forfeit earnest money as a result. Class T Distribution Declaration On October 21, 2015, our board of directors declared a daily distribution with respect to our Class T Shares in the amount of $0.00164383561 per share (equivalent to an annualized distribution rate of 6.34% assuming the Class T Share was purchased for $9.47) on the outstanding Class T Shares, payable to stockholders of record of such shares as shown on our books as of the close of business on each day of the period commencing on October 21, 2015 and ending December 31, 2015. Such distributions payable to each stockholder of record during a month will be paid on such date of the following month as our Chief Executive Officer may determine. Preferred Equity In October 2015, we redeemed $25.0 million in the Preferred Equity Investment. In November 2015, we redeemed all remaining Preferred Units and paid all Current Distributions and Deferred Distributions, all of which totaled approximately $22.0 million. Offering Status As of November 9, 2015, in connection with our Offering we have issued approximately 13.3 million Class A Shares and approximately 0.2 million Class T Shares for gross proceeds of approximately $132.2 million and $1.8 million, respectively.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) as contained within the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and the rules and regulations of the Securities and Exchange Commission (“SEC”).
Principles of Consolidation	Principles of Consolidation Our financial statements, and the financial statements of our Operating Partnership, including its wholly-owned subsidiaries, are consolidated in the accompanying consolidated financial statements. The portion of these entities not wholly-owned by us is presented as noncontrolling interests. All significant intercompany accounts and transactions have been eliminated in consolidation.
Consolidation Considerations	Consolidation Considerations Current accounting guidance provides a framework for identifying a variable interest entity (“VIE”) and determining when a company should include the assets, liabilities, noncontrolling interests, and results of activities of a VIE in its consolidated financial statements. In general, a VIE is an entity or other legal structure used to conduct activities or hold assets that either (1) has an insufficient amount of equity to carry out its principal activities without additional subordinated financial support, (2) has a group of equity owners that are unable to make significant decisions about its activities, or (3) has a group of equity owners that do not have the obligation to absorb losses or the right to receive returns generated by its operations. Generally, a VIE should be consolidated if a party with an ownership, contractual, or other financial interest in the VIE (a variable interest holder) has the power to direct the VIE’s most significant activities and the obligation to absorb losses or right to receive benefits of the VIE that could be significant to the VIE. A variable interest holder that consolidates the VIE is called the primary beneficiary. Upon consolidation, the primary beneficiary generally must initially record all of the VIE’s assets, liabilities, and noncontrolling interest at fair value and subsequently account for the VIE as if it were consolidated based on majority voting interest. As of September 30, 2015 and December 31, 2014, we had not entered into contracts/interests that would be deemed to be variable interests in VIEs.
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 will adjust 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 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 will be mitigated by only investing in or through major financial institutions.
Restricted Cash	Restricted Cash Restricted cash consists primarily of impound reserve accounts for property taxes, insurance and capital improvements in connection with the requirements of one of our loan agreements.
Real Estate Purchase Price Allocation	Real Estate Purchase Price Allocation We account for acquisitions in accordance with amended 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. We also consider whether in-place, market leases represent an intangible asset. We preliminarily recorded approximately $13.9 million in intangible assets to recognize the value of in-place leases related to our acquisitions during 2015. We do not expect, nor to date have we recorded, intangible assets for the value of customer relationships because we expect we will not have concentrations of significant customers and the average customer turnover will be fairly frequent. Our acquisition-related transaction costs are required to be expensed as incurred. During both the three months ended September 30, 2015 and 2014, we expensed approximately $0.3 million of acquisition-related transaction costs. During the nine months ended September 30, 2015 and 2014, we expensed approximately $3.1 million and $0.7 million of acquisition-related transaction costs, respectively. Should the initial accounting for an acquisition be incomplete by the end of a reporting period that falls within the measurement period, we will report provisional amounts in our financial statements. During the measurement period, we will adjust the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date and we will record those adjustments to our financial statements.
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 may not be recoverable. When indicators of potential impairment are present that indicate that the carrying amounts of the assets may not be recoverable, we will assess the recoverability of the assets by determining whether the carrying value of the long-lived assets will be recovered through the undiscounted future operating cash flows expected from the use of the asset and its eventual disposition. In the event that such expected undiscounted future cash flows do not exceed the carrying value, we will adjust the value of the long-lived assets to the fair value and recognize an impairment loss. For the nine months ended September 30, 2015 and 2014, no impairment losses were recognized.
Equity Investments	Equity Investments Investments in unconsolidated real estate joint ventures and VIEs in which we are not the primary beneficiary, where we have significant influence, but not control, will be recorded under the equity method of accounting in our consolidated financial statements. Under the equity method, our investments in real estate ventures will be stated at cost and adjusted for our share of net earnings or losses and reduced by distributions. Equity in earnings of real estate ventures will be 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 minority interests will be accounted for under the cost method. Under the cost method, our investments in real estate ventures will be carried at cost and adjusted for other-than-temporary declines in fair value, distributions representing a return of capital and additional investments.
Revenue Recognition	Revenue Recognition Management believes that all of our leases are operating leases. Rental income is recognized in accordance with the terms of the leases, which generally are month-to-month. Revenues from any long-term operating leases are recognized on a straight-line basis over the term of the lease. The excess of rents received over amounts contractually due pursuant to the underlying leases is included in accounts payable and accrued liabilities in our consolidated balance sheets and contractually due but unpaid rent is included in other assets.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts Tenant accounts receivable, which is included in other assets in the accompanying consolidated balance sheets, is reported net of an allowance for doubtful accounts. Management’s estimate of the allowance is based upon a review of the current status of tenant accounts receivable. It is reasonably possible that management’s estimate of the allowance will change in the future.
Real Estate Facilities	Real Estate Facilities Real estate facilities are recorded 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 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 30-35 years Site Improvements 7-10 years As described in Note 1, after the close of the Merger all of our properties are being re-branded under the Extra Space name. As such, during the three months ended September 30, 2015, the depreciable lives for capitalized SmartStop branded signs were reduced to their estimated remaining useful lives. Depreciation expense for the three months ended September 30, 2015 includes approximately $230,000 of accelerated depreciation related to the SmartStop branded signs.
Depreciation of Personal Property Assets	Depreciation of Personal Property Assets Personal property assets consist primarily of furniture, fixtures and equipment and are depreciated on a straight-line basis over the estimated useful lives generally ranging from 3 to 5 years, and are included in other assets on our consolidated balance sheets.
Intangible Assets	Intangible Assets We have allocated a portion of our real estate purchase price to in-place leases. We are amortizing in-place leases on a straight-line basis over the estimated future benefit period. As of September 30, 2015 and December 31, 2014, the gross amounts allocated to in-place lease intangibles was approximately $16.1 million and $2.2 million respectively, and accumulated amortization of in-place lease intangibles totaled approximately $4.4 million and $0.2 million, respectively.
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 September 30, 2015 and December 31, 2014, accumulated amortization of deferred financing costs totaled approximately $0.4 million and $4,000, respectively.
Organizational and Offering Costs	Organizational and Offering Costs Our Advisor may fund organization and offering costs on our behalf. We will be required to reimburse our Advisor for such organization and offering costs; provided, however, our Advisor must reimburse us within 60 days after the end of the month in 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. Such costs will be recognized as a liability when we have a present responsibility to reimburse our Advisor, which is defined in our Advisory Agreement as the date we satisfied the minimum offering requirements of our Offering (which occurred on May 23, 2014). If at any point in time we determine that the total organization and offering costs are expected to exceed 3.5% of the gross proceeds anticipated to be received from the Primary Offering, we will recognize such excess as a capital contribution from our Advisor. As of September 30, 2015, we do not believe total organization and offering costs will exceed 3.5% of the gross proceeds anticipated to be received 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 adopted a share redemption program that will enable stockholders to sell their shares to us in limited circumstances. We record amounts that are redeemable under the share redemption program as redeemable common stock in the accompanying consolidated balance sheet since the shares are redeemable at the option of the holder and therefore their redemption is outside our control. The maximum amount redeemable under our share redemption program is limited to the number of shares we can repurchase with the amount of the net proceeds from the sale of shares under the distribution reinvestment plan. However, accounting guidance states that determinable amounts that can become redeemable 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 are considered to be temporary equity and are presented as redeemable common stock in the accompanying consolidated balance sheets. In addition, current accounting guidance requires, among other things, that financial instruments that represent a mandatory obligation for us to repurchase shares be classified as liabilities and reported at settlement value. Our redeemable common shares will be contingently redeemable at the option of the holder. When we determine we have a mandatory obligation to repurchase shares under the share redemption program, we will reclassify such obligations from temporary equity to a liability based upon their respective settlement values. Through September 30, 2015 we received one request for the redemption of 1,750 shares which was fulfilled in July 2015.
Accounting for Equity Awards	Accounting for Equity Awards The cost of restricted stock is required to be measured based on the grant date fair value and the cost recognized over the relevant service period.
Fair Value Measurements	Fair Value Measurements 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 will use when measuring fair value: • Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access; • Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as interest rates and yield curves that are observable at commonly quoted intervals; and • Level 3 inputs are unobservable inputs for the assets or liabilities that are typically based on an entity’s own assumptions as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the fair value measurement will fall within the lowest level that is significant to the fair value measurement in its entirety. The accounting guidance for fair value measurements and disclosures provides a framework for measuring fair value and establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. In determining fair value, we will utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as consider counterparty credit risk in our assessment of fair value. Considerable judgment will be necessary to interpret Level 2 and 3 inputs in determining fair value of our financial and non-financial assets and liabilities. Accordingly, there can be no assurance that the fair values we will present will be indicative of amounts that may ultimately be realized upon sale or other disposition of these assets. Financial and non-financial assets and liabilities measured at fair value on a non-recurring basis in our consolidated financial statements consist of real estate and related liabilities assumed related to our acquisitions. The fair values of these assets and liabilities were determined as of the acquisition dates using widely accepted valuation techniques, including (i) discounted cash flow analysis, which considers, among other things, leasing assumptions, growth rates, discount rates and terminal capitalization rates, (ii) income capitalization approach, which considers prevailing market capitalization rates, and (iii) comparable sales activity. In general, we consider multiple valuation techniques when measuring fair values. However, in certain circumstances, a single valuation technique may be appropriate. All of the fair values of the assets and liabilities as of the acquisition dates were derived using Level 3 inputs. The carrying amounts of cash and cash equivalents, other assets, accounts payable and accrued liabilities, distributions payable and amounts due to affiliates will approximate fair value because of the relatively short-term nature of these instruments. The table below summarizes our fixed rate notes payable at September 30, 2015 and December 31, 2014. The estimated fair value of financial instruments is subjective in nature and is dependent on a number of important assumptions, including discount rates and relevant comparable market information associated with each financial instrument. The fair value of the fixed rate notes payable was estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. The use of different market assumptions and estimation methodologies may have a material effect on the reported estimated fair value amounts. Accordingly, the estimates presented below are not necessarily indicative of the amounts we would realize in a current market exchange. September 30, 2015 December 31, 2014 Fair Value Carrying Value Fair Value Carrying Value Fixed Rate Secured Debt $ 13,560,000 $ 13,305,056 $ 13,500,000 $ 13,494,871 To comply with GAAP, we incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of derivative contracts for the effect of non-performance risk, we will consider the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.
Noncontrolling Interest in Consolidated Entities	Noncontrolling Interest in Consolidated Entities We account for the noncontrolling interest in our Operating Partnership in accordance with the related accounting guidance. Due to our control through our general partnership interest in our Operating Partnership and the limited rights of the limited partner, our Operating Partnership, including its wholly-owned subsidiaries, are consolidated with the Company and the limited partner interest is reflected as a noncontrolling interest in the accompanying consolidated balance sheet. The noncontrolling interest shall be attributed its 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, 2014. To qualify as a REIT, we must continue to meet certain organizational and operational requirements, including a requirement to distribute at least 90% of the REIT’s ordinary taxable income to stockholders. 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. 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 filed elections to treat our TRS as a taxable REIT subsidiary effective January 1, 2014. In general, the TRS performs additional services for our customers and generally engages in any real estate or non-real estate related business. The TRS is subject to corporate federal and state income tax. The TRS follows accounting guidance which requires the use of the asset and liability method. Deferred income taxes represent the tax effect of future differences between the book and tax bases of assets and liabilities.
Per Share Data	Per Share Data Basic earnings per share attributable for all periods presented are computed by dividing net income (loss) by the weighted average number of shares outstanding during the period. Diluted earnings per share are computed by dividing net income (loss) by the weighted average number of shares outstanding, including all restricted stock grants as though fully vested. For the three and nine months ended September 30, 2015, and 2014, 7,500 Class A Shares, and none, respectively, of unvested restricted stock were not included in diluted weighted average shares as such common 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. In July 2015, the FASB voted to defer the effective date by one year to annual reporting periods (including interim periods within those periods) beginning after December 15, 2017 and early adoption is permitted. This ASU shall still be applied using either a full retrospective or modified retrospective approach. 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. In April 2015, the FASB issued ASU 2015-03, “Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. ASU 2015-03 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. In September 2015, the FASB issued ASU 2015-16, “Business Combinations: Simplifying the Accounting for Measurement-Period Adjustments”. ASU 2015-16 requires an acquirer in a business combination to recognize adjustments to estimated amounts identified during the measurement period in the reporting period in which the adjustment amounts are determined. The acquirer must record the effect of the adjustments on earnings as if the accounting had been completed at the acquisition date and the acquirer must disclose in its financial statements the portion of the amounts recorded in each line item of current-period earnings that would have been recorded in previous periods if the adjustments to estimated amounts had been recognized as of the acquisition date. The update is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years, with early adoption permitted for financial statements that have not been issued. 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.
