ORGANIZATION AND NATURE OF OPER

ORGANIZATION AND NATURE OF OPERATIONS	12 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND NATURE OF OPERATIONS	ORGANIZATION AND NATURE OF OPERATIONS National Storage Affiliates Trust was organized in the state of Maryland on May 16, 2013 and is a fully integrated, self-administered and self-managed real estate investment trust focused on the self storage sector. As used herein, "NSA," the "Company," "we," "our," and "us" refers to National Storage Affiliates Trust and its consolidated subsidiaries, except where the context indicates otherwise. The Company intends to elect and qualify as a real estate investment trust for U.S. federal income tax purposes ("REIT") commencing with its taxable year ended December 31, 2015. Through our controlling interest as the sole general partner of NSA OP, LP (our "operating partnership"), a Delaware limited partnership formed on February 13, 2013, we are focused on the ownership, operation, and acquisition of self storage properties located within the top 100 metropolitan statistical areas ("MSAs") throughout the United States. Pursuant to the Agreement of Limited Partnership (as amended, the "LP Agreement") of our operating partnership, our operating partnership is authorized to issue Class A Units ("OP units"), different series of Class B Units ("subordinated performance units"), and Long-Term Incentive Plan Units ("LTIP units"). We also own certain of our self storage properties through other consolidated limited partnership subsidiaries of our operating partnership, which we refer to as "DownREIT partnerships." The DownREIT partnerships issue equity ownership interests that are intended to be economically equivalent to our OP units ("DownREIT OP units") and subordinated performance units ("DownREIT subordinated performance units"). The Company completed its initial public offering on April 28, 2015, pursuant to which it sold 20,000,000 shares of the Company's common shares of beneficial interest, $0.01 par value per share ("common shares"), at a price of $13.00 per share. As part of the offering, the Company granted the underwriters an option to purchase up to 3,000,000 additional common shares within thirty days after the offering. The underwriters exercised their option in full and, on May 18, 2015, purchased an additional 3,000,000 common shares. These transactions resulted in net proceeds to the Company of approximately $278.1 million , after deducting the underwriting discount and before additional expenses associated with the offering. The Company contributed the net proceeds from its initial public offering to our operating partnership in exchange for 23,000,000 OP units. OP Units are the economic equivalent of the Company's common shares and for each common share issued by the Company, our operating partnership issues a corresponding OP Unit to NSA in exchange for the contribution of the proceeds from the share issuances. Prior to the completion of our initial public offering, the Company was 100% owned by National Storage Affiliates Holdings, LLC ("Holdings"), an entity formed on February 13, 2013. Holdings' only assets consisted of 126,400 OP units in our operating partnership which were acquired for cash of $0.6 million , and 1,000 common shares which were issued for nominal consideration on June 7, 2013. While our operating partnership was also formed on February 13, 2013, it did not commence operations until April 1, 2013. Holdings served as the general partner of our operating partnership until June 7, 2013 when the Company was appointed as the sole general partner. Due to the existence of common control by Holdings, the Company is deemed to have commenced its operations concurrently with the April 1, 2013 date when our operating partnership began its operations. Immediately prior to the completion of our initial public offering on April 28, 2015, we redeemed the 1,000 common shares held by Holdings for no consideration. The Company's predecessor for accounting purposes consists of SecurCare Portfolio Holdings, LLC and SecurCare Value Properties, Ltd. (collectively, "NSA Predecessor"), entities whose principal owner is the Company's chief executive officer. NSA Predecessor does not represent a single legal entity, but a combination of these two legal entities under common control prior to formation of the Company. NSA Predecessor owned and operated a total of 110 self storage properties, which are included in the accompanying NSA Predecessor financial statements, in California, Colorado, Georgia, Mississippi, North Carolina, Oklahoma, and Texas. As discussed in Note 5, NSA Predecessor contributed to the Company a total of 88 of NSA Predecessor's self storage properties, consisting of 23 self storage properties on June 10, 2013, and an additional 65 self storage properties that were contributed on April 1, 2014. For financial reporting purposes the contribution of all 88 self storage properties by NSA Predecessor was accounted for as a reorganization of entities under common control, whereby all 88 self storage properties were treated as if they were acquired on April 1, 2013 (the date our operating partnership's operations commenced). Of the 110 self storage properties owned by NSA Predecessor, 22 self storage properties did not meet the criteria for contribution to the Company and are excluded from the accompanying NSA financial statements. The historical carrying value of the net assets of NSA Predecessor as of April 1, 2013 is reflected in Note 5, along with a reconciliation to the net assets contributed and liabilities assumed for the 88 self storage properties contributed by NSA Predecessor. In addition, the 110 self storage properties owned by NSA Predecessor are reflected in the accompanying NSA Predecessor financial statements. Where the "Company" is referenced in comparisons of financial results for any date prior to April 1, 2013, the financial information for such period relates solely to NSA Predecessor, notwithstanding "Company" or "NSA" being the reference. The Company owned 277 self storage properties in 16 states with approximately 15.8 million rentable square feet in approximately 123,000 storage units as of December 31, 2015 . These properties are managed with local operational focus and expertise by our participating regional operators ("PROs"). These PROs are SecurCare Self Storage, Inc. and its controlled affiliates ("SecurCare"), Kevin Howard Real Estate Inc., d/b/a Northwest Self Storage and its controlled affiliates ("Northwest"), Optivest Properties LLC and its controlled affiliates ("Optivest"), Guardian Storage Centers LLC and its controlled affiliates ("Guardian"), Move It Self Storage and its controlled affiliates ("Move It"), and Arizona Mini Storage Management Company d/b/a Storage Solutions and its controlled affiliates ("Storage Solutions").

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying financial statements are presented on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles ("GAAP"). Principles of Consolidation and Combination The Company's financial statements include the accounts of our operating partnership and its controlled subsidiaries. The combined financial statements of NSA Predecessor include the accounts of NSA Predecessor and all entities which were under common control. All significant intercompany balances and transactions have been eliminated in the consolidation and combination of entities. When the Company obtains an economic interest in an entity, the Company evaluates the entity to determine if the entity is deemed a variable interest entity ("VIE"), and if the Company is deemed to be the primary beneficiary, in accordance with authoritative guidance issued on the consolidation of VIEs. When an entity is not deemed to be a VIE, the Company considers the provisions of additional guidance to determine whether the general partner controls a limited partnership or similar entity when the limited partners have certain rights. The Company consolidates (i) entities that are VIEs and of which the Company is deemed to be the primary beneficiary, and (ii) entities that are non-VIEs which the Company controls and for which limited partners lack both substantive participating rights and the ability to dissolve or remove the Company without cause. Noncontrolling Interests All of the limited partner equity interests in our operating partnership not held by the Company are reflected as noncontrolling interests. Noncontrolling interests also include ownership interests in DownREIT partnerships held by entities other than our operating partnership. In the consolidated statements of operations, we allocate net income (loss) attributable to noncontrolling interests to arrive at net income (loss) attributable to National Storage Affiliates Trust. For transactions that result in changes to the Company's ownership interest in our operating partnership, the carrying amount of noncontrolling interests is adjusted to reflect such changes. The difference between the fair value of the consideration received or paid and the amount by which the noncontrolling interests is adjusted is reflected as an adjustment to additional paid-in capital on the consolidated balance sheets. Self Storage Properties Self storage properties are carried at historical cost less accumulated depreciation and any impairment losses. Major replacements and betterments, which improve or extend the life of an asset, are capitalized. Expenditures for ordinary repairs and maintenance are expensed as incurred and are included in property operating expenses. Estimated depreciable lives of self storage properties are determined by considering the age and other indicators about the condition of the assets at the respective dates of acquisition, resulting in a range of estimated useful lives for assets within each category. All self storage property assets are depreciated using the straight-line method. Buildings and improvements are depreciated over estimated useful lives primarily between seven and 40 years ; furniture and equipment are depreciated over estimated useful lives primarily between three and 10 years . When a self storage property is acquired in a business combination, the purchase price of the acquired self storage property is allocated to land, buildings and improvements, furniture and equipment, customer in-place leases, assumed real estate leasehold interests, other assets acquired and liabilities assumed, based on the estimated fair value of each component. When a portfolio of self storage properties is acquired, the purchase price is allocated to the individual self storage properties based on the fair value determined using an income approach with appropriate risk-adjusted capitalization rates, which take into account the relative size, age and location of the individual self storage properties. Cash and Cash Equivalents The Company considers all highly-liquid investments purchased with original maturities of three months or less to be cash equivalents. From time to time, the Company maintains cash balances in financial institutions in excess of federally insured limits. The Company has never experienced a loss that resulted from exceeding federally insured limits. Restricted Cash The Company's restricted cash consists of escrowed funds deposited with financial institutions for real estate taxes, insurance and other reserves for capital improvements in accordance with our loan agreements. Customer In-place Leases In allocating the purchase price for an acquisition accounted for as a business combination, the Company determines whether the acquisition includes intangible assets. The Company allocates a portion of the purchase price to an intangible asset attributed to the value of customer in-place leases. This intangible asset is amortized to expense using the straight-line method over 12 months , the estimated average rental period for our customers. Amortization expense for customer in-place leases amounted to $12.0 million and $8.3 million for the years ended December 31, 2015 and 2014, respectively, and $2.6 million for the nine months ended December 31, 2013. Substantially all of the leases in place at acquired properties are at market rates, as the leases are month-to-month contracts. Impairment of Long-Lived Assets The Company evaluates long-lived assets for impairment when events and circumstances indicate that there may be impairment. When events or changes in circumstances indicate that the Company's long-lived assets may not be recoverable, the carrying value of these long-lived assets is compared to the undiscounted future net operating cash flows, plus a terminal value attributable to the assets. If an asset's carrying value is not considered recoverable, an impairment loss is recorded to the extent the net carrying value of the asset exceeds the fair value. For the periods presented, no assets were determined to be impaired under this policy. Debt Issuance Costs Debt issuance costs are amortized over the estimated life of the related debt using the straight-line method, which approximates the effective interest rate method. Amortization of debt issuance costs is included in interest expense in the accompanying statements of operations. Revenue Recognition Management has determined that all of our leases are operating leases. Substantially all leases may be terminated on a month-to-month basis and rental income is recognized ratably over the lease term using the straight-line method. Rents received in advance are deferred and recognized on a straight-line basis over the related lease term associated with the prepayment. Promotional discounts and other incentives are recognized as a reduction to rental income over the applicable lease term. Other property-related revenue consists of ancillary revenues such as tenant insurance-related access fees and commissions and sales of storage supplies which are recognized in the period earned. The Company recognizes gains from disposition of facilities only upon closing in accordance with the guidance on sales of real estate. Payments received from purchasers prior to closing are recorded as deposits. Profit on real estate sold is recognized using the full accrual method upon closing when the collectability of the sales price is reasonably assured and the Company is not obligated to perform significant activities after the sale. Profit may be deferred in whole or part until the sale meets the requirements of profit recognition on sales under this guidance. Advertising Costs The Company incurs advertising costs primarily attributable to internet, directory and other advertising. Advertising costs are included in property operating expenses in the accompanying statements of operations. These costs are expensed in the period in which the cost is incurred. The Company incurred advertising costs of $2.4 million and $1.7 million for the years ended December 31, 2015 and 2014 , and $0.8 million for the nine months ended December 31, 2013. NSA Predecessor recognized $0.2 million in advertising expense for the three months ended March 31, 2013. Acquisition Costs, Organizational and Offering Expenses The Company incurs title, legal and consulting fees, and other costs associated with the completion of self storage property acquisitions. Such costs are included in acquisition costs in the accompanying statements of operations in the period in which they are incurred. The Company also incurs legal fees and filing fees in connection with the organization of the Company and its subsidiaries, which are charged to expense in the period incurred. Commissions, legal fees and other costs that are directly associated with equity offerings are capitalized as deferred offering costs, pending a determination of the success of the offering. Deferred offering costs related to successful offerings are charged to equity in the period it is determined that the offering was successful. Deferred offering costs related to unsuccessful offerings are recorded as expense in the period when it is determined that the offering is unsuccessful. Other costs related to equity offerings, such as audit fees associated with the operations of our self storage properties for periods preceding the related contribution and formation transactions, are charged to expense in the period incurred. Income Taxes NSA Predecessor was comprised of a limited partnership and a limited liability company. Under applicable federal and state income tax rules, the allocated share of net income or loss from the limited partnership and the limited liability company was reported in the income tax returns of the respective partners and members. Accordingly, NSA Predecessor did not generate an income tax benefit or expense for the three months ended March 31, 2013. Through December 31, 2014, the Company did not have a profit and loss sharing interest in our operating partnership and did not have any other operations that were subject to taxation. Accordingly, the Company did not generate an income tax benefit or expense for the period from its inception through December 31, 2014. The Company intends to elect to be taxed as a REIT under sections 856 through 860 of the U.S. Internal Revenue Code (the "Code") commencing with the taxable year ended December 31, 2015. To qualify as a REIT, among other things, the Company is required to distribute at least 90% of its REIT taxable income to its shareholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to federal income tax on the earnings distributed currently to its shareholders that it derives from its REIT qualifying activities. If the Company fails to qualify as a REIT in any taxable year, and is unable to avail itself of certain provisions set forth in the Code, all of the Company's taxable income would be subject to federal and state income taxes at regular corporate rates, including any applicable alternative minimum tax. The Company will not be required to make distributions with respect to income derived from the activities conducted through subsidiaries that the Company elects to treat as taxable REIT subsidiaries ("TRS") for federal income tax purposes. Certain activities that the Company undertakes must be conducted by a TRS, such as performing non-customary services for its customers and holding assets that the Company is not permitted to hold directly. A TRS is subject to federal and state income taxes. The Company did not have any unrecognized tax benefits related to uncertain tax positions as of December 31, 2015 and 2014 . Future amounts of accrued interest and penalties, if any, related to uncertain tax positions will be recorded as a component of income tax expense. The Company does not expect that the amount of unrecognized tax benefits will change significantly in the next 12 months. The Company's material taxing jurisdiction is the U.S. federal jurisdiction; due to the Company's recent formation, the 2015 , 2014 and 2013 tax years are the only periods that remain open to examination by these taxing jurisdictions. Tax years prior to 2012 for the limited partnership and limited liability company that comprise NSA Predecessor are no longer subject to examination. On June 25, 2014, the Company formed NSA TRS, LLC ("NSA TRS"), a Delaware limited liability company. The Company has elected to treat NSA TRS as a TRS, and consequently, NSA TRS is subject to U.S. federal and state corporate income taxes. Deferred tax assets and liabilities are recognized to the extent of any differences between the financial reporting and tax bases of assets and liabilities. No material deferred tax assets and liabilities were recorded as of December 31, 2015 or 2014. Earnings per Share Basic earnings per share is calculated based on the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated by further adjusting for the dilutive impact using the treasury stock method for any share options and unvested share equivalents outstanding during the period and the if-converted method for any convertible securities outstanding during the period. Equity-Based Awards The measurement and recognition of compensation cost for all equity-based awards granted to officers, employees and consultants is based on estimated fair values. Compensation cost is recognized on a straight-line basis over the requisite service periods of each award with non-graded vesting. For awards granted which contain a graded vesting schedule and the only condition for vesting is a service condition, compensation cost is recognized as an expense on a straight-line basis over the requisite service period as if the award was, in substance, a single award. For awards granted for which vesting is subject to a performance condition, including awards that vested upon completion of the Company's initial public offering, compensation cost is recognized over the requisite service period if and when the Company concludes it is probable that the performance condition will be achieved. The estimated fair value of all equity-based awards issued to PROs and their affiliates in connection with self storage property acquisitions is included in the cost of the respective acquisitions. The estimated fair value of such awards is measured at the date the self storage properties are acquired, as this date represents satisfaction of the performance condition and coincides with the award vesting. Derivative Financial Instruments The Company carries all derivative financial instruments on the balance sheet at fair value. Fair value of derivatives is determined by reference to observable prices that are based on inputs not quoted on active markets, but corroborated by market data. The accounting for changes in the fair value of a derivative instrument depends on whether the derivative has been designated and qualifies as part of a hedging relationship. The use of derivative instruments has been limited to interest rate swap and cap agreements. The fair values of derivative instruments are included in other assets and accounts payable and accrued liabilities in the accompanying balance sheets. For derivative instruments not designated as cash flow hedges, the unrealized gains and losses are included in interest expense in the accompanying statements of operations. For derivatives designated as cash flow hedges, the effective portion of the changes in the fair value of the derivatives is initially reported in accumulated other comprehensive loss in our balance sheets and subsequently reclassified into earnings when the hedged transaction affects earnings. The valuation of interest rate swap and cap agreements is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates (forward curves) derived from observable market interest rate forward curves. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. Fair Value Measurements When measuring fair value of financial instruments that are required to be recorded or disclosed at fair value, the Company uses a three-tier measurement hierarchy which prioritizes the inputs used to calculate fair value. These tiers include Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Segment Reporting The Company manages its business as one reportable segment consisting of investments in self storage properties located in the United States. Although we operate in several markets, these operations have been aggregated into one reportable segment based on the similar economic characteristics amongst all markets. Reclassifications Certain amounts in the financial statements and related notes have been reclassified to conform to the current year presentation. Such reclassifications do not impact our previously reported financial position or net income (loss). Allocation of Net Income (Loss) The distribution rights and priorities set forth in our operating partnership's LP Agreement differ from what is reflected by the underlying percentage ownership interests of the unitholders. Accordingly, we allocate GAAP income (loss) utilizing the hypothetical liquidation at book value ("HLBV") method, in which we allocate income or loss based on the change in each unitholders' claim on the net assets of our operating partnership at period end after adjusting for any distributions or contributions made during such period. The HLBV method is commonly applied to equity investments where cash distribution percentages vary at different points in time and are not directly linked to an equity holder's ownership percentage. The HLBV method is a balance sheet-focused approach. A calculation is prepared at each balance sheet date to determine the amount that unitholders would receive if our operating partnership were to liquidate all of its assets (at GAAP net book value) and distribute the resulting proceeds to its creditors and unitholders based on the contractually defined liquidation priorities. The difference between the calculated liquidation distribution amounts at the beginning and the end of the reporting period, after adjusting for capital contributions and distributions, is used to derive each unitholder's share of the income (loss) for the period. Due to the stated liquidation priorities and because the HLBV method incorporates non-cash items such as depreciation expense, in any given period, income or loss may be allocated disproportionately to unitholders as compared to their respective ownership percentage in our operating partnership, and net income (loss) attributable to National Storage Affiliates Trust could be more or less net income than actual cash distributions received and more or less income or loss than what may be received in the event of an actual liquidation. Additionally, the HLBV method could result in net income attributable to National Storage Affiliates Trust during a period when the Company reports a consolidated net loss, or net income attributable to National Storage Affiliates Trust in excess of the Company's consolidated net income. Other Comprehensive Income (Loss) The Company has cash flow hedge derivative instruments that are measured at fair value with unrealized gains or losses recognized in other comprehensive income (loss) with a corresponding adjustment to accumulated other comprehensive loss within equity, as discussed further in Note 13. Under the HLBV method of allocating income (loss) discussed above, a calculation is prepared at each balance sheet date by applying the HLBV method including, and excluding, the assets and liabilities resulting from our cash flow hedge derivative instruments to determine comprehensive income (loss) attributable to National Storage Affiliates Trust. As a result of the distribution rights and priorities set forth in our operating partnership's LP Agreement, all amounts of consolidated other comprehensive income (loss) for the year ended December 31, 2015 were allocated to noncontrolling interests, as presented within the accompanying statements of comprehensive income (loss). Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in GAAP when it becomes effective. ASU 2014-09 is effective for the Company on January 1, 2018, with early application permitted for the Company on January 1, 2017. ASU 2014-09 permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis, which modifies the current consolidation guidance. The Company is required to adopt ASU 2015-02 for annual and interim financial statements issued for the year ending December 31, 2016. Upon adoption by the Company, ASU 2015-02 permits the use of either the modified retrospective or cumulative effect transition method. The Company is finalizing its analysis of ASU 2015-02 and does not expect ASU 2015-02 to have a material impact on its consolidated financial statements and related disclosures. In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest, which requires the presentation of debt issuance costs as a direct deduction from the carrying amount of the related debt liabilities. The Company does not expect ASU 2015-03 to have a material impact on the Company's results from operations, however, adoption will result in the reclassification of certain debt issuance costs as an asset and a corresponding reduction in the carrying amount of the Company's debt financings applied retrospectively to all periods. The Company is required to adopt this ASU for annual and interim financial statements issued for the year ending December 31, 2016. In September 2015, the FASB issued ASU 2015-16, Business Combinations—Simplifying the Accounting for Measurement-Period Adjustments, which requires an acquirer of a business to recognize adjustments to provisional amounts that are identified during the business combination's measurement period in the reporting period in which the adjustment amounts are determined rather than retrospectively. ASU 2015-16 is effective for the Company on January 1, 2016, with early application permitted. The Company elected to adopt ASU 2015-16 during the year ended December 31, 2015 and the adoption did not have a material impact on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02, Leases, which amends the existing guidance for accounting for leases, including requiring lessees to recognize most leases on-balance sheet as lease liabilities with corresponding right-of-use assets. ASU 2016-02 is effective for the Company on January 1, 2019, with early application permitted. ASU 2016-02 requires a modified retrospective approach, with entities applying the new guidance at the beginning of the earliest period presented in the financial statements in which they first apply the new standard, with certain elective transition relief. The Company is evaluating the effect that ASU 2016-02 will have on its operating leases, consolidated financial statements and related disclosures.

NONCONTROLLING INTERESTS

NONCONTROLLING INTERESTS	12 Months Ended

Noncontrolling Interest [Abstract]
NONCONTROLLING INTERESTS	NONCONTROLLING INTERESTS All of the limited partner equity interests in our operating partnership not held by the Company are reflected as noncontrolling interests. Noncontrolling interests also include ownership interests in DownREIT partnerships held by entities other than our operating partnership. NSA is the general partner of our operating partnership and is authorized to cause our operating partnership to issue additional partner interests, including OP units and subordinated performance units, at such prices and on such other terms as it determines in its sole discretion. As of December 31, 2015 and 2014 , units reflecting noncontrolling interests consisted of the following: December 31, 2015 2014 OP units 21,556,006 18,817,088 Subordinated performance units 9,302,989 8,447,679 LTIP units 2,784,761 2,689,780 DownREIT units DownREIT OP units 1,834,786 1,275,979 DownREIT subordinated performance units 4,386,999 3,009,884 Total 39,865,541 34,240,410 While the Company controls our operating partnership and manages the daily operations of our operating partnership's business, the Company did not have an ownership interest or share in our operating partnership's profits and losses prior to the completion of the Company's initial public offering. The increase in OP Units, DownREIT OP units, subordinated performance units, and DownREIT subordinated performance units outstanding from December 31, 2014 to December 31, 2015 was related to the acquisition of self storage properties and a centralized call center. The increase in LTIP units outstanding from December 31, 2014 to December 31, 2015 was due to the issuance of compensatory LTIP units to third party consultants, employees and a PRO. Distributions The Company is entitled to cause our operating partnership to make distributions to OP unit holders and subordinated performance unit holders in our operating partnership from time to time in its sole discretion. To the extent distributions are made, the holders of OP units are entitled to receive distributions with respect to all of the Company's self storage property portfolio and the holders of each series of subordinated performance units are entitled to receive distributions with respect to the portfolio of self storage properties to which the series of subordinated performance units relates. To the extent that there is available operating cash flow or capital transaction proceeds, subject to maintaining the Company's qualification as a REIT, the Company may cause our operating partnership to make distributions. Conversion of LTIP Units LTIP units are a special class of partnership interest in our operating partnership that allow the holder to participate in the ordinary and liquidating distributions received by holders of the OP units (subject to the achievement of specified levels of profitability by our operating partnership or the achievement of certain events). LTIP units were first granted under the 2013 Long-Term Incentive Plan (the "2013 Plan"). Some of the granted LTIP units vested immediately or upon completion of the Company's initial public offering. Others vest upon the contribution of self storage properties or along a schedule at certain times prior to December 31, 2017. LTIP units do not have full parity with OP units with respect to liquidating distributions and do not receive ordinary distributions until such parity is reached pursuant to the terms of the LP Agreement. If such parity is reached under the LP Agreement, upon vesting, vested LTIP units may be converted into an equal number of OP units, and thereafter have all the rights of OP units, including redemption rights. Subordinated Performance Unit Conversion Rights Other than in connection with a retirement event, after a minimum of two years from the later of completion of the Company's initial public offering or the issuance of subordinated performance units in connection with the initial contribution of a PRO's self storage properties to the Company, holders of subordinated performance units can voluntarily convert such units for OP units (inclusive of a specified conversion penalty) upon the achievement of certain performance thresholds with respect to a specific self storage portfolio. OP Unit Redemption Rights The holders of OP units are not entitled to elect redemption until one year after the later of the closing of the Company's initial public offering or the issuance of the OP units. Following such one year period, the Company will have the ability to satisfy the redemption request by issuing common shares on a one -for-one basis or the payment of cash, solely at the option of the Company. Accordingly, the limited partner interests are included in noncontrolling interests within equity in the accompanying balance sheets as of December 31, 2015 and 2014.

Business Combinations [Abstract]
SELF STORAGE PROPERTY ACQUISITIONS AND DISPOSITIONS	SELF STORAGE PROPERTY ACQUISITIONS AND DISPOSITIONS The Company acquired 58 self storage properties with an estimated fair value of $313.0 million during the year ended December 31, 2015 and 83 self storage properties with an estimated fair value of $479.1 million during the year ended December 31, 2014 . During the year ended December 31, 2015 , 25 self storage properties with an estimated fair value of $134.4 million were acquired by us from our PROs, and 13 self storage properties with an estimated fair value of $65.3 million were acquired by us from an entity which is managed by a member of our board of trustees. During the year ended December 31, 2014 , 60 self storage properties with an estimated fair value of $382.1 million were acquired by us from our PROs. These self storage property acquisitions were accounted for as business combinations whereby the Company recognized the estimated fair value of the acquired assets and assumed liabilities on the respective dates of such acquisitions. The Company allocated the total purchase price to the estimated fair value of tangible and intangible assets acquired, and liabilities assumed. The Company allocated a portion of the purchase price to identifiable intangible assets consisting of customer in-place leases which were recorded at estimated fair value of $8.5 million and $13.2 million during the years ended December 31, 2015 and 2014 , respectively, resulting in a total fair value of $304.5 million and $465.9 million allocated to real estate during the years ended December 31, 2015 and 2014 , respectively. The following table summarizes, by calendar quarter, the consideration for the business combinations completed by the Company during the year s ended December 31, 2015 and 2014 (dollars in thousands): Acquisitions Closed During the Three Months Ended: Summary of Consideration Number of Properties Value of OP Equity (2) Settlement of Note Receivable Liabilities Assumed (Assets Acquired) Noncontrolling Interests (4) Total Fair Value Cash (1) Mortgages (3) Other 3/31/2015 6 $ 6,991 $ 8,954 $ 1,778 $ 16,442 $ 70 $ 6,770 $ 41,005 6/30/2015 21 41,277 22,971 — 30,547 288 — 95,083 9/30/2015 15 84,673 10,188 — 2,866 512 8,327 106,566 12/31/2015 16 39,626 1,402 — 23,643 (359 ) 6,040 70,352 Total 58 $ 172,567 $ 43,515 $ 1,778 $ 73,498 $ 511 $ 21,137 $ 313,006 3/31/2014 1 $ 1,900 $ — $ — $ — $ 5 $ — $ 1,905 6/30/2014 36 94,580 72,803 — — 986 — 168,369 9/30/2014 31 77,252 39,547 — 59,546 1,070 35,442 212,857 12/31/2014 15 55,242 28,254 — 6,270 342 5,855 95,963 Total 83 $ 228,974 $ 140,604 $ — $ 65,816 $ 2,403 $ 41,297 $ 479,094 (1) Includes cash advances during 2014 of $11.0 million for notes receivable that subsequently settled as a reduction of cash payable for self storage property acquisitions.

We estimate the portion of the fair value of the net assets owned by noncontrolling interests based on the fair value of the real estate and debt assumed. As discussed in Note 12, three of the 58 self storage properties acquired during the year ended December 31, 2015 , and one of the 83 self storage properties acquired during the year ended December 31, 2014, are subject to non-cancelable leasehold interest agreements that are classified as operating leases. The results of operations for these business combinations are included in our statements of operations beginning on the respective closing date for each acquisition. The accompanying statements of operations includes aggregate revenue of $19.3 million and operating income of $2.4 million related to the 58 self storage properties acquired during the year ended December 31, 2015 . For the year ended December 31, 2014 , the accompanying statements of operations includes aggregate revenue of $21.8 million and operating income of $2.1 million related to the 83 self storage properties acquired during such period. Acquisition costs in the accompanying statements of operations include consulting fees, transaction expenses, and other costs related to business combinations, which amounted to $4.8 million and $9.6 million for the years ended December 31, 2015 and 2014 , respectively. Self Storage Properties Under Contract As of March 9, 2016, the Company was under contract to acquire an additional 22 self storage properties, and during January and February 2016, the Company acquired 16 self storage properties for approximately $85.0 million , as discussed further in Note 15. Unaudited Pro Forma Financial Information The unaudited pro forma financial information set forth below reflects adjustments to the historical data of the Company and NSA Predecessor to give effect to the acquisitions and related financing activities for (i) nine of the 16 self storage properties discussed in Note 15 that were acquired subsequent to December 31, 2015 , as if each acquisition had occurred on January 1, 2015 (unaudited pro forma financial information is not presented for seven of the self storage properties acquired subsequent to December 31, 2015 because the information required is not available to the Company), (ii) 42 of the 58 self storage properties acquired during the year ended December 31, 2015 , as if the acquisitions had occurred on January 1, 2014 (unaudited pro forma financial information is not presented for 16 of the self storage properties acquired during the year ended December 31, 2015 since the information required is not available to the Company), (iii) each of the 83 self storage properties that were acquired during the year ended December 31, 2014 , as if each acquisition had occurred on January 1, 2013, and (iv) 43 self-storage property acquisitions that occurred during 2013, as if each had occurred on January 1, 2012. As described in greater detail above, given that certain information with respect to the self storage properties we acquired during the year ended December 31, 2015 and subsequent to December 31, 2015 is not available to the Company, readers of this Annual Report on Form 10-K and investors are cautioned not to place undue reliance on our unaudited pro forma financial information.

Debt Disclosure [Abstract]
DEBT FINANCING	DEBT FINANCING The Company's outstanding debt as of December 31, 2015 and 2014 is summarized as follows (dollars in thousands): Interest December 31, Rate (1) 2015 2014 Credit Facility: Revolving line of credit 2.03% $ 187,975 $ 166,217 Term loan 2.75% 200,000 144,558 Unsecured term loan — — 50,000 Fixed rate mortgages payable 3.93% 182,637 153,416 Variable rate mortgages payable — — 83,500 Total $ 570,612 $ 597,691 (1) Represents the effective interest rate as of December 31, 2015 . Effective interest rate incorporates the stated rate plus the impact of interest rate cash flow hedges and discount and premium amortization, if applicable. For the revolving line of credit, the effective interest rate excludes fees for unused borrowings. Credit Facility On August 13, 2015, the Company entered into an amendment with a syndicated group of lenders consisting of 11 financial institutions to increase the total borrowing capacity under its unsecured credit facility (the "credit facility"), which was originally entered into on April 1, 2014, by $125.0 million for a total credit facility of $550.0 million . The Company has an additional expansion option under the credit facility, which if exercised, would provide for a total borrowing capacity of $700.0 million . The credit facility consists of two components: • A senior revolving credit facility (the "revolving line of credit"), which provides for a total borrowing commitment up to $350.0 million , whereby the Company may borrow, repay and re-borrow amounts under the revolving line of credit. The borrowing commitment is subject to a borrowing base calculation, which only includes self storage properties with an occupancy rate of at least 75% on a combined basis. As of December 31, 2015 , we had the capacity to borrow an additional $162.0 million , subject to the borrowing base calculation. The Company is required to pay a fee which ranges from 0.20% to 0.25% of unused borrowings under the revolving line of credit. As of December 31, 2015 , the pricing grid under the revolving line of credit provides for an interest rate equal to one-month London Interbank Offered Rate ("LIBOR") plus 1.60% . The revolving line of credit matures in March 2017 and the Company may elect an extension of the maturity date until March 2018 by paying an extension fee equal to 0.20% of the total borrowing commitment at the time of the extension. • A $200.0 million senior term loan (the "term loan") which provides that amounts borrowed may be repaid at any time but not re-borrowed. As of December 31, 2015 , the pricing grid under the term loan provides for an interest rate equal to one-month LIBOR plus 1.50% . No principal payments are required under the term loan until the maturity date in March 2018. The terms of the credit facility limit the Company's ability to make distributions, incur additional debt, and acquire or sell significant assets. The credit facility requires compliance with certain financial and non-financial covenants, including a maximum total leverage ratio, a minimum fixed charge coverage ratio, and minimum net worth, which were not impacted by the increase amendment discussed above. At December 31, 2015 , the Company was in compliance with all such covenants. Unsecured Term Loan On April 1, 2014, the Company entered into a senior unsecured term loan (the "unsecured term loan") with a syndicated group of lenders consisting of three financial institutions. The unsecured term loan provided for maximum borrowings of $50.0 million . The loan originally matured on April 1, 2015 but was extended until October 1, 2015 in exchange for a prescribed fee of $250,000 . There was a mandatory repayment of this loan upon the occurrence of a capital event (such as completion of the Company's initial public offering) as defined in the loan agreement, and following the completion of our initial public offering during the year ended December 31, 2015, we used a portion of the net proceeds from our initial public offering to repay the $50.0 million unsecured term loan. The repayment resulted in a $0.2 million write-off of unamortized debt issuance costs. Prior to the repayment, payments were limited to interest only, to be paid on a monthly basis, and the outstanding principal balance bore interest at one-month LIBOR plus 5.00% . Fixed Rate Mortgages Payable Fixed rate mortgages have scheduled maturities at various dates through November 2024, and have effective interest rates that range from 2.20% to 5.00% . Principal and interest are generally payable monthly or in monthly interest-only payments with balloon payments due at maturity. As discussed in Note 6, we assumed fixed rate mortgages of $73.5 million in connection with 31 of the properties acquired during the year ended December 31, 2015 and $65.8 million in connection with 16 of the properties acquired during the year ended December 31, 2014 . We repaid $34.7 million of these assumed mortgages during the year ended December 31, 2015 . Variable Rate Mortgages Payable Variable rate mortgages had contractual maturities at various dates through October 2015, and had effective interest rates that ranged from 2.43% to 9.65% . Following the completion of our initial public offering during the year ended December 31, 2015, we used a portion of the net proceeds from our initial public offering to repay all $83.5 million of the outstanding variable rate mortgages. In connection with the repayments, the Company incurred a $0.5 million prepayment penalty and recorded a $0.2 million write-off of unamortized debt issuance costs. Prior to the repayment, principal and interest on this debt was generally payable in monthly interest-only payments with balloon payments due at maturity. Future Debt Maturities Based on existing debt agreements in effect as of December 31, 2015 , the future maturities of outstanding borrowings under the Company's credit facility and fixed rate mortgages are presented in the table below (in thousands): Year Ending December 31, Contractual Principal Premium Amortization Total 2016 $ 14,130 $ 1,697 $ 15,827 2017 204,129 1,100 205,229 2018 209,192 985 210,177 2019 3,468 917 4,385 2020 37,635 564 38,199 After 2021 96,332 463 96,795 $ 564,886 $ 5,726 $ 570,612

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
EQUITY-BASED AWARDS	EQUITY-BASED AWARDS The Company grants awards in the form of LTIP units and restricted common shares to provide equity based incentive compensation to members of our senior management team, our independent trustees, advisers, consultants, other personnel, and as consideration for self storage property acquisitions. LTIP Units LTIP units are a special class of partnership interest in our operating partnership that allow the holder to participate in the ordinary and liquidating distributions received by holders of the OP units (subject to the achievement of specified levels of profitability by our operating partnership or the achievement of certain events). LTIP units do not have full parity with OP units with respect to liquidating distributions and do not receive ordinary distributions until such parity is reached pursuant to the terms of the LP Agreement. If such parity is reached under the LP Agreement, upon vesting, vested LTIP units may be converted into an equal number of OP units, and thereafter have all the rights of OP units, including redemption rights. The grant date fair value for all LTIP units was based on the fair value of comparable equity instruments of the Company such as its OP units, discounted for certain rights available to the similar equity instrument holders and not available to the LTIP unit holders. LTIP units were first granted under the 2013 Long-Term Incentive Plan (the "2013 Plan"), which authorized up to 2.5 million LTIP units for issuance. In connection with our initial public offering, we terminated the 2013 Plan but the awards granted thereunder remained outstanding after its termination. Additional LTIP units are issued pursuant to the LP Agreement discussed in Note 1. Through December 31, 2015 , an aggregate of 2,474,710 LTIP units have been issued under the 2013 Plan and 310,051 LTIP units have been issued under the LP Agreement. Some of the granted LTIP units vested immediately or upon completion of the Company's initial public offering. Others vest upon the contribution of self storage properties or along a schedule at certain times prior to December 31, 2017. Compensatory Grants The following table summarizes activity for compensatory LTIP units for the years ended December 31, 2015 and 2014 and the nine months ended December 31, 2013: Year Ended December 31, Nine Months Ended December 31, 2015 2014 2013 Number of LTIP units Weighted Average Grant-Date Fair Value Number of LTIP units Weighted Average Grant-Date Fair Value Number of LTIP units Weighted Average Grant-Date Fair Value Outstanding unvested at beginning of year 509,166 $ 10.07 287,600 $ 9.28 — $ — Granted 6,000 13.00 378,550 10.37 406,600 9.28 Vested (278,901 ) 9.84 (156,984 ) 9.35 (119,000 ) 9.28 Unvested at end of year 236,265 $ 10.41 509,166 $ 10.07 287,600 $ 9.28 The aggregate fair value of compensatory LTIP units that vested during the years ended December 31, 2015 and 2014 and the nine months ended December 31, 2013 was $2.7 million , $1.5 million and $1.1 million , respectively. Total compensation cost recognized for compensatory LTIP units was $3.0 million , $1.5 million and $1.1 million for the years ended December 31, 2015 and 2014 and the nine months ended December 31, 2013, respectively. At December 31, 2015 , total unvested compensation cost not yet recognized was $2.3 million . The Company expects to recognize this compensation cost over a period of approximately 2.0 years . If the grantee has a termination of service for any reason during the vesting period, the unvested LTIP units will be forfeited. Compensation expense related to LTIP units granted to members of our senior management team, our independent trustees, advisers, consultants and other personnel is included in general and administrative expense in the accompanying statements of operations. Acquisition Consideration Grants On December 31, 2013, the Company granted 1,683,560 LTIP units under the 2013 Plan to PROs, including NSA Predecessor, as part of the consideration for their respective self storage property acquisitions and contributions. The following table presents the number of units issued and units vested for acquisition grants for the years ended December 31, 2015 and 2014 and the nine months ended December 31, 2013: Total LTIP units Units issued on December 31, 2013 1,683,560 Units vested upon issuance in 2013 related to: Properties contributed or sourced by PROs (314,410 ) Contributions by NSA Predecessor (1) (107,080 ) Total unvested units, December 31, 2013 1,262,070 Units vested in 2014 related to: Properties contributed or sourced by PROs (2) (379,970 ) Contributions by NSA Predecessor (1) (359,200 ) Total unvested units, December 31, 2014 522,900 Units vested in 2015 related to: Properties contributed or sourced by PROs (2) (99,100 ) Total unvested units, December 31, 2015 423,800 (3) (1) The contribution of self storage properties by NSA Predecessor was accounted for as a reorganization of entities under common control and, accordingly, no value was recognized in the Company's financial statements for these LTIP units. (2) The aggregate fair value of vested LTIP units associated with self storage properties contributed or sourced by PROs represents consideration for the self storage property acquisitions set forth in Note 6. (3) As of December 31, 2015 , the remaining unvested LTIP units will vest as additional self storage properties are contributed or sourced by the PROs. The fair value of such LTIP units will be recorded as additional acquisition consideration based on the fair value in the period such acquisitions are completed. The aggregate fair value of purchase consideration recognized during the years ended December 31, 2015 and 2014 and the nine months ended December 31, 2013 was $1.4 million , $3.7 million and $2.9 million , respectively. LP Agreement Grants to Consultants Pursuant to the LP Agreement, during the years ended December 31, 2015 and 2014 , the Company issued 88,981 and 221,070 LTIP units, respectively, that were immediately vested to consultants that provided acquisition services that are included in acquisition costs in the accompanying statements of operations. The aggregate fair value of LTIP units was $1.0 million for the year ended December 31, 2015 and $2.1 million for the year ended December 31, 2014. Restricted Common Shares Restricted common shares were first granted under the 2015 National Storage Affiliates Trust Equity Incentive Plan (the "2015 Plan"), which authorizes our compensation, nominating, and corporate governance committee to grant share options, restricted common shares, phantom shares, dividend equivalent rights, LTIP units and other restricted limited partnership units issued by our operating partnership and other equity-based awards up to an aggregate of 5% of the common shares issued and outstanding from time to time on a fully diluted basis (assuming, if applicable, the exercise of all outstanding options and the conversion of all warrants and convertible securities, including OP units and LTIP units, into common shares). As of December 31, 2015, we did not have outstanding under our equity compensation plan, any options, warrants or rights to purchase our common shares. Through December 31, 2015 , an aggregate of 17,210 restricted common shares have been issued under the 2015 Plan. These restricted common shares vest over a period of 2.5 years . The following table summarizes activity for restricted common shares for the year ended December 31, 2015 : Year Ended December 31, 2015 Number of Restricted Common Shares Weighted Average Grant-Date Fair Value Outstanding at beginning of year — $ — Granted 17,210 12.40 Vested (6,000 ) 12.40 Forfeited (210 ) 12.40 Unvested at end of year 11,000 $ 12.40 The aggregate fair value and total compensation cost of restricted common shares that vested during the year ended December 31, 2015 was $0.1 million . At December 31, 2015 , total unvested compensation cost not yet recognized was $0.1 million . The Company expects to recognize this compensation cost over a period of approximately 2.0 years .

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE The following table sets forth the computation of basic and diluted earnings (loss) per common share for the years ended December 31, 2015 and 2014 , and the nine months ended December 31, 2013 (in thousands, except per share amounts): Year Ended December 31, Nine Months Ended December 31, 2015 2014 2013 Earnings (loss) per common share - basic and diluted Numerator Net income (loss) $ 4,796 $ (16,357 ) $ (10,481 ) Net loss attributable to noncontrolling interests 7,644 16,357 10,481 Net income (loss) attributable to National Storage Affiliates Trust 12,440 — — Distributed and undistributed earnings allocated to participating securities (9 ) — — Net income (loss) attributable to common shareholders - basic 12,431 — — Effect of assumed conversion of dilutive securities (4,919 ) — — Net income (loss) attributable to common shareholders - diluted $ 7,512 $ — $ — Denominator Weighted average shares outstanding - basic 15,463 1 1 Effect of dilutive securities: Weighted average OP units outstanding 15,697 — — Weighted average DownREIT OP unit equivalents outstanding 1,171 — — Weighted average LTIP units outstanding 1,272 — — Subordinated performance units and DownREIT subordinated performance unit equivalents 11,806 — — Weighted average shares outstanding - diluted 45,409 1 1 Earnings (loss) per share - basic $ 0.80 $ — $ — Earnings (loss) per share - diluted $ 0.17 $ — $ — Dividends declared per common share $ 0.54 $ — $ — As discussed in Note 3, the Company did not have an ownership interest or share in our operating partnership's profits and losses prior to the completion of the Company's initial public offering. As a result, all of our operating partnership's profits and losses for the period from January 1, 2015 to April 28, 2015 and the years ended December 31, 2014 and 2013 were allocated to noncontrolling interests. Outstanding equity interests of our operating partnership and DownREIT partnerships are considered potential common shares for purposes of calculating diluted earnings (loss) per share as the unitholders may, through the exercise of redemption rights, obtain common shares, subject to various restrictions. Basic earnings per share is calculated based on the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated by further adjusting for the dilutive impact using the treasury stock method for unvested LTIP units subject to a service condition outstanding during the period and the if-converted method for any convertible securities outstanding during the period. Generally, following certain lock-out periods, OP units in our operating partnership are redeemable for cash or, at our option, exchangeable for common shares on a one -for-one basis, subject to certain adjustments and DownREIT OP units are redeemable for cash or, at our option, exchangeable for OP units in our operating partnership on a one -for-one basis, subject to certain adjustments in each case. LTIP units may also, under certain circumstances, be convertible into OP units, which are exchangeable for common shares as described above. Certain LTIP units vested at the date of grant or upon the completion of the Company's initial public offering and certain LTIP units will vest upon the satisfaction of a future service condition. Vested LTIP units and unvested LTIP units that vest based on a service condition are allocated income or loss in a similar manner as OP units. Unvested LTIP units subject to a service condition are evaluated for dilution using the treasury stock method. For the year ended December 31, 2015 , 236,265 unvested LTIP units that vest based on a service condition are excluded from the calculation of diluted earnings (loss) per share as they are not dilutive to earnings (loss) per share. In addition, certain LTIP units vest upon the future acquisition of properties sourced by PROs. For the year ended December 31, 2015 , 423,800 unvested LTIP units that vest upon the future acquisition of properties are excluded from the calculation of diluted earnings (loss) per share because the contingency for the units to vest has not been attained as of the end of the reported periods. Subordinated performance units may also, under certain circumstances, be convertible into OP units which are exchangeable for common shares as described above, and DownREIT subordinated performance units may, under certain circumstances, be exchangeable for subordinated performance units on a one -for-one basis. Subordinated performance units are only convertible into OP units, after a two year lock-out period and then generally (i) at the holder's election only upon the achievement of certain performance thresholds relating to the properties to which such subordinated performance units relate or (ii) at our election upon a retirement event of a PRO that holds such subordinated performance units or upon certain qualifying terminations. Although subordinated performance units and DownREIT subordinated performance units may only be convertible after a two year lock-out period, we assume a hypothetical conversion of each subordinated performance unit (including each DownREIT subordinated performance unit) into OP units (with subsequently assumed redemption into common shares) for the purposes of calculating diluted weighted average common shares. This hypothetical conversion is calculated using historical financial information prior to and since the completion of the Company's initial public offering on April 28, 2015, and as a result, is not necessarily indicative of the subsequent results of operations, cash flows or financial position of the Company following the initial public offering or upon expiration of the two-year lock-out period on conversions. Participating securities, which consist of unvested restricted common shares, receive dividends equal to those received by common shares. The effect of participating securities for the periods presented above is calculated using the two-class method of allocating distributed and undistributed earnings.

Affiliate Call Center Services On April 1, 2015, the Company acquired a centralized call center for 50,000 OP units from SecurCare, an affiliate of NSA Predecessor. Because the Company and SecurCare are under common control, the assets acquired and liabilities assumed were recorded at SecurCare's historical carrying value, which was a nominal amount as of the acquisition date. SecurCare continues to manage call center services to support self storage property operations and the fees paid to SecurCare for these services for the nine months ended December 31, 2015 are included in the supervisory and administrative fees discussed above. The call center utilizes approximately 1,500 square feet in one of the Company's self storage properties acquired from NSA Predecessor for annual rent of approximately $25,000 . Prior to the acquisition, for the year s ended December 31, 2015 and 2014 , the Company incurred call center charges of $0.2 million and $0.5 million , respectively. For the nine months ended December 31, 2013, the Company incurred call center charges of $0.3 million . Such call center costs are included in property operating expenses in the accompanying statements of operations. For the three months ended March 31, 2013, NSA Predecessor incurred call center charges of $0.1 million .

Brokerage Fees During the year s ended December 31, 2015 and 2014 , the Company incurred fees of $0.2 million and $0.3 million , respectively, in connection with its acquisition of certain self storage properties which were sourced by the PROs. During the nine months ended December 31, 2013, the Company incurred fees of $0.5 million in connection with its acquisition of certain self storage properties which were sourced by the PROs. These expenses are included in acquisition costs in the accompanying statements of operations. In connection with self storage properties contributed by NSA Predecessor, during the year ended December 31, 2014 the Company recognized a $2.7 million contractually obligated transaction expense payable to SecurCare, an affiliate of NSA Predecessor. In April 2014, the Company issued subordinated performance units in full payment of this amount. Due Diligence Costs During the year ended December 31, 2015 , the Company reimbursed certain PROs for $0.6 million of due diligence costs related to certain self storage property acquisitions sourced by the PROs. These expenses are included in acquisition costs in the accompanying statements of operations. During the year ended December 31, 2014 , in connection with the acquisition of certain self storage properties sourced by an affiliate of NSA Predecessor, the Company agreed to reimburse the related party for $0.2 million of due diligence costs related to the acquisitions. Notes Receivable In connection with the acquisition of two self storage properties, the Company made a bridge loan of $4.8 million to a PRO on February 28, 2014. This loan provided for interest at 5.16% and was collateralized by self storage properties that were subsequently acquired by the Company on May 30, 2014, at which time the note was repaid. In connection with the planned acquisition of certain self storage properties, the Company made a bridge loan of approximately $8.0 million to a PRO on July 1, 2014. This loan did not bear interest and was repaid as the related self storage properties were acquired. Through December 31, 2014 , 13 of the self storage properties had been acquired and bridge loan advances totaling $6.2 million were applied to offset the acquisition consideration otherwise payable by the Company. As of December 31, 2014 , the bridge loan balance of $1.8 million is included in other assets in the accompanying balance sheet. In January 2015, the remaining balance of the bridge loan was applied to offset the acquisition consideration otherwise payable by the Company related to two self storage property acquisitions. In connection with the acquisition of 16 self storage properties from PROs during the year ended December 31, 2014, the Company assumed certain mortgages that provided for interest at above-market rates. The sellers of the self storage properties agreed to reimburse the Company for the difference between the fair value and the contractual value of the assumed mortgages which amounted to $5.2 million . Due to the structure of the transaction, the amount owed to the Company was considered a receivable for the issuance of equity and was recorded as an offset against equity. During the year ended December 31, 2015 , the Company received above-market interest reimbursements from the sellers totaling $1.6 million . In addition, in exchange for $1.4 million of principal payment reimbursements received related to these assumed mortgages, the Company issued 85,130 OP units to the sellers during the year ended December 31, 2015. Notes Payable During the year ended December 31, 2015 , in connection with the acquisition of self storage properties owned in DownREIT partnerships, the Company entered into bridge loan agreements for $5.3 million payable to principals of the PRO that contributed the properties.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Operating Leases In January 2015 the Company acquired three self storage properties that are subject to non-cancelable leasehold interest agreements that are classified as operating leases. These lease agreements expire between 2034 and 2051, inclusive of extension options that we anticipate exercising. The lease agreements provide for fixed rental increases throughout the term of the lease, and, accordingly, the Company recognizes lease expense on a straight-line basis over the expected lease terms. Rent expense under these ground lease agreements is included in property operating expenses in the accompanying statements of operations and amounted to $0.9 million for the year ended December 31, 2015. In September 2014 the Company acquired a self storage property that is subject to a non-cancelable ground lease agreement that is classified as an operating lease. This agreement provides for a minimum lease term that expires in June 2045 and provides for extension options that if exercised would extend the lease expiration until June 2075. The estimated useful life of the related self storage property extends through 2054; therefore, the Company intends to exercise extension options whereby the lease term would expire in 2055. The ground lease agreement provides for fixed increases throughout the term of the lease and, accordingly, the Company recognizes lease expense on a straight-line basis over the expected lease term. Rent expense under this ground lease agreement is included in property operating expenses in the accompanying statements of operations and amounted to $0.1 million and less than $0.1 million for the years ended December 31, 2015 and 2014 , respectively. In March 2014, the Company entered into a non-cancelable operating lease that expires in July 2020 for its corporate headquarters in Greenwood Village, Colorado. Under the terms of the office lease, the Company obtained an option to extend the lease for an additional term of five years at then current market rates. The office lease provides for an abated rent period and the value of this inducement is being accounted for as a reduction to rent expense over the term of the lease. Rent expense related to this office lease is included in general and administrative expenses in the accompanying statements of operations and amounted to $0.1 million for the years ended December 31, 2015 and 2014 . As of December 31, 2015 , future minimum cash payments under the Company's operating leases are as follows (in thousands): Year Ending December 31, Ground Leases Office Lease Total 2016 $ 833 $ 116 $ 949 2017 847 119 966 2018 852 122 974 2019 857 125 982 2020 902 74 976 2021 through 2055 26,405 — 26,405 $ 30,696 $ 556 $ 31,252 Legal Proceedings The Company is subject to litigation, claims, and assessments that may arise in the ordinary course of its business activities. Such matters include contractual matters, employment related issues, and regulatory proceedings. Although occasional adverse decisions or settlements may occur, the Company believes that the final disposition of such matters will not have a material adverse effect on the Company's financial position, results of operations, or liquidity.

FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Recurring Fair Value Measurements The Company sometimes limits its exposure to interest rate fluctuations by entering into interest rate swap or cap agreements. The interest rate swap agreements moderate the Company's exposure to interest rate risk by effectively converting the interest on variable rate debt to a fixed rate. The interest rate cap agreements effectively limit our exposure to interest rate risk by providing a ceiling on the underlying variable interest rate. Our interest rate cap agreements are not material to our financial position and results of operations and there were no interest rate cap agreements outstanding as of December 31, 2015. We measure our interest rate swap derivatives at fair value on a recurring basis. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive loss and are subsequently reclassified into earnings in the period that the hedged transaction affects earnings. The ineffective portion of the change in fair value of the derivatives is recognized directly into earnings. Information regarding our interest rate swaps measured at fair value, which are classified within Level 2 of the GAAP fair value hierarchy, is presented below (dollars in thousands): Interest Rate Swaps Designated as Cash Flow Hedges Non-hedge accounting Interest Rate Swaps Total Fair value at December 31, 2013 $ — $ 70 $ 70 Unrealized losses included in interest expense — (277 ) (277 ) Losses on interest rate swaps reclassified into interest expense from accumulated other comprehensive loss 1,077 — 1,077 Unrealized losses included in accumulated other comprehensive loss (1,942 ) — (1,942 ) Fair value at December 31, 2014 $ (865 ) $ (207 ) $ (1,072 ) Unrealized losses included in interest expense — (63 ) (63 ) Designation of interest rate swap as a cash flow hedge (270 ) 270 — Cash flow hedge ineffectiveness 15 — 15 Losses on interest rate swaps reclassified into interest expense from accumulated other comprehensive loss 1,699 — 1,699 Unrealized losses included in accumulated other comprehensive loss (1,551 ) — (1,551 ) Fair value at December 31, 2015 $ (972 ) $ — $ (972 ) As of December 31, 2014 , the Company had outstanding interest rate swaps with aggregate notional amounts of $125.0 million designated as cash flow hedges and one interest rate swap with a notional amount of $7.6 million that was not designated as a cash flow hedge. During the year ended December 31, 2015 , the Company designated this interest rate swap as a cash flow hedge following the expansion of its credit facility. As of December 31, 2015 , the Company had outstanding interest rate swaps with aggregate notional amounts of $199.4 million designated as cash flow hedges. As of December 31, 2015 , the Company's swaps had a weighted average remaining term of 2.4 years . The fair value of these swaps are presented within other assets and accounts payable and accrued liabilities in the accompanying balance sheets, and the Company recognizes any changes in the fair value as an adjustment of accumulated other comprehensive loss within equity to the extent of their effectiveness. If the forward rates at December 31, 2015 remain constant, the Company estimates that during the next 12 months , the Company would reclassify into earnings approximately $1.1 million of the unrealized losses included in accumulated other comprehensive loss. If market interest rates increase above the 1.25% weighted average fixed rate under these interest rate swaps the Company will benefit from net cash payments due to us from our counterparty to the interest rate swaps. There were no transfers between levels during the year s ended December 31, 2015 and 2014 . For financial assets and liabilities that utilize Level 2 inputs, the Company utilizes both direct and indirect observable price quotes, including LIBOR yield curves. The Company uses valuation techniques for Level 2 financial assets and liabilities which include LIBOR yield curves at the reporting date as well as assessing counterparty credit risk. Counterparties to these contracts are highly rated financial institutions. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with the Company's derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by the Company and the counterparties. As of December 31, 2015 and 2014 , the Company determined that the effect of credit valuation adjustments on the overall valuation of its derivative positions are not significant to the overall valuation of its derivatives. Therefore, the Company has determined that its derivative valuations are appropriately classified in Level 2 of the fair value hierarchy. Fair Value Disclosures The carrying values of cash and cash equivalents, restricted cash, trade receivables, and accounts payable and accrued liabilities reflected in the balance sheets at December 31, 2015 and 2014 , approximate fair value due to the short term nature of these financial assets and liabilities. The carrying value of variable rate debt financing reflected in the balance sheets at December 31, 2015 and 2014 approximates fair value as the changes in their associated interest rates reflect the current market and credit risk is similar to when the loans were originally obtained. The fair values of fixed rate mortgages were estimated using the discounted estimated future cash payments to be made on such debt; the discount rates used approximated current market rates for loans, or groups of loans, with similar maturities and credit quality (categorized within Level 2 of the fair value hierarchy). The combined carrying value of our fixed rate mortgages payable was approximately $182.6 million as of December 31, 2015 with a fair value of approximately $189.3 million . In determining the fair value, the Company estimated a weighted average market interest rate of approximately 3.41% , compared to the weighted average contractual interest rate of 5.10% . The combined carrying value of our fixed rate mortgages was approximately $153.4 million as of December 31, 2014 with a fair value of approximately $158.3 million . In determining the fair value as of December 31, 2014 , the Company estimated a weighted average market interest rate of approximately 3.59% , compared to the weighted average contractual interest rate of 5.11% .

SUMMARY OF SIGNIFICANT ACCOUN25

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying financial statements are presented on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles ("GAAP")
Principles of Consolidation and Noncontrolling Interest	Principles of Consolidation and Combination The Company's financial statements include the accounts of our operating partnership and its controlled subsidiaries. The combined financial statements of NSA Predecessor include the accounts of NSA Predecessor and all entities which were under common control. All significant intercompany balances and transactions have been eliminated in the consolidation and combination of entities. When the Company obtains an economic interest in an entity, the Company evaluates the entity to determine if the entity is deemed a variable interest entity ("VIE"), and if the Company is deemed to be the primary beneficiary, in accordance with authoritative guidance issued on the consolidation of VIEs. When an entity is not deemed to be a VIE, the Company considers the provisions of additional guidance to determine whether the general partner controls a limited partnership or similar entity when the limited partners have certain rights. The Company consolidates (i) entities that are VIEs and of which the Company is deemed to be the primary beneficiary, and (ii) entities that are non-VIEs which the Company controls and for which limited partners lack both substantive participating rights and the ability to dissolve or remove the Company without cause. Noncontrolling Interests All of the limited partner equity interests in our operating partnership not held by the Company are reflected as noncontrolling interests. Noncontrolling interests also include ownership interests in DownREIT partnerships held by entities other than our operating partnership. In the consolidated statements of operations, we allocate net income (loss) attributable to noncontrolling interests to arrive at net income (loss) attributable to National Storage Affiliates Trust. For transactions that result in changes to the Company's ownership interest in our operating partnership, the carrying amount of noncontrolling interests is adjusted to reflect such changes. The difference between the fair value of the consideration received or paid and the amount by which the noncontrolling interests is adjusted is reflected as an adjustment to additional paid-in capital on the consolidated balance sheets.
Self Storage Properties	Self Storage Properties Self storage properties are carried at historical cost less accumulated depreciation and any impairment losses. Major replacements and betterments, which improve or extend the life of an asset, are capitalized. Expenditures for ordinary repairs and maintenance are expensed as incurred and are included in property operating expenses. Estimated depreciable lives of self storage properties are determined by considering the age and other indicators about the condition of the assets at the respective dates of acquisition, resulting in a range of estimated useful lives for assets within each category. All self storage property assets are depreciated using the straight-line method. Buildings and improvements are depreciated over estimated useful lives primarily between seven and 40 years ; furniture and equipment are depreciated over estimated useful lives primarily between three and 10 years . When a self storage property is acquired in a business combination, the purchase price of the acquired self storage property is allocated to land, buildings and improvements, furniture and equipment, customer in-place leases, assumed real estate leasehold interests, other assets acquired and liabilities assumed, based on the estimated fair value of each component. When a portfolio of self storage properties is acquired, the purchase price is allocated to the individual self storage properties based on the fair value determined using an income approach with appropriate risk-adjusted capitalization rates, which take into account the relative size, age and location of the individual self storage properties.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly-liquid investments purchased with original maturities of three months or less to be cash equivalents. From time to time, the Company maintains cash balances in financial institutions in excess of federally insured limits.
Restricted Cash	Restricted Cash The Company's restricted cash consists of escrowed funds deposited with financial institutions for real estate taxes, insurance and other reserves for capital improvements in accordance with our loan agreements.
Customer In-place Leases	Customer In-place Leases In allocating the purchase price for an acquisition accounted for as a business combination, the Company determines whether the acquisition includes intangible assets. The Company allocates a portion of the purchase price to an intangible asset attributed to the value of customer in-place leases. This intangible asset is amortized to expense using the straight-line method over 12 months , the estimated average rental period for our customers. Amortization expense for customer in-place leases amounted to $12.0 million and $8.3 million for the years ended December 31, 2015 and 2014, respectively, and $2.6 million for the nine months ended December 31, 2013. Substantially all of the leases in place at acquired properties are at market rates, as the leases are month-to-month contracts.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company evaluates long-lived assets for impairment when events and circumstances indicate that there may be impairment. When events or changes in circumstances indicate that the Company's long-lived assets may not be recoverable, the carrying value of these long-lived assets is compared to the undiscounted future net operating cash flows, plus a terminal value attributable to the assets. If an asset's carrying value is not considered recoverable, an impairment loss is recorded to the extent the net carrying value of the asset exceeds the fair value.
Debt Issuance Costs	Debt Issuance Costs Debt issuance costs are amortized over the estimated life of the related debt using the straight-line method, which approximates the effective interest rate method. Amortization of debt issuance costs is included in interest expense in the accompanying statements of operations.
Revenue Recognition	Revenue Recognition Management has determined that all of our leases are operating leases. Substantially all leases may be terminated on a month-to-month basis and rental income is recognized ratably over the lease term using the straight-line method. Rents received in advance are deferred and recognized on a straight-line basis over the related lease term associated with the prepayment. Promotional discounts and other incentives are recognized as a reduction to rental income over the applicable lease term. Other property-related revenue consists of ancillary revenues such as tenant insurance-related access fees and commissions and sales of storage supplies which are recognized in the period earned. The Company recognizes gains from disposition of facilities only upon closing in accordance with the guidance on sales of real estate. Payments received from purchasers prior to closing are recorded as deposits. Profit on real estate sold is recognized using the full accrual method upon closing when the collectability of the sales price is reasonably assured and the Company is not obligated to perform significant activities after the sale. Profit may be deferred in whole or part until the sale meets the requirements of profit recognition on sales under this guidance.
Advertising Costs	Advertising Costs The Company incurs advertising costs primarily attributable to internet, directory and other advertising. Advertising costs are included in property operating expenses in the accompanying statements of operations. These costs are expensed in the period in which the cost is incurred.
Acquisition, Organizational And Offering Costs	Acquisition Costs, Organizational and Offering Expenses The Company incurs title, legal and consulting fees, and other costs associated with the completion of self storage property acquisitions. Such costs are included in acquisition costs in the accompanying statements of operations in the period in which they are incurred. The Company also incurs legal fees and filing fees in connection with the organization of the Company and its subsidiaries, which are charged to expense in the period incurred. Commissions, legal fees and other costs that are directly associated with equity offerings are capitalized as deferred offering costs, pending a determination of the success of the offering. Deferred offering costs related to successful offerings are charged to equity in the period it is determined that the offering was successful. Deferred offering costs related to unsuccessful offerings are recorded as expense in the period when it is determined that the offering is unsuccessful. Other costs related to equity offerings, such as audit fees associated with the operations of our self storage properties for periods preceding the related contribution and formation transactions, are charged to expense in the period incurred.
Income Taxes	Income Taxes NSA Predecessor was comprised of a limited partnership and a limited liability company. Under applicable federal and state income tax rules, the allocated share of net income or loss from the limited partnership and the limited liability company was reported in the income tax returns of the respective partners and members. Accordingly, NSA Predecessor did not generate an income tax benefit or expense for the three months ended March 31, 2013. Through December 31, 2014, the Company did not have a profit and loss sharing interest in our operating partnership and did not have any other operations that were subject to taxation. Accordingly, the Company did not generate an income tax benefit or expense for the period from its inception through December 31, 2014. The Company intends to elect to be taxed as a REIT under sections 856 through 860 of the U.S. Internal Revenue Code (the "Code") commencing with the taxable year ended December 31, 2015. To qualify as a REIT, among other things, the Company is required to distribute at least 90% of its REIT taxable income to its shareholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to federal income tax on the earnings distributed currently to its shareholders that it derives from its REIT qualifying activities. If the Company fails to qualify as a REIT in any taxable year, and is unable to avail itself of certain provisions set forth in the Code, all of the Company's taxable income would be subject to federal and state income taxes at regular corporate rates, including any applicable alternative minimum tax. The Company will not be required to make distributions with respect to income derived from the activities conducted through subsidiaries that the Company elects to treat as taxable REIT subsidiaries ("TRS") for federal income tax purposes. Certain activities that the Company undertakes must be conducted by a TRS, such as performing non-customary services for its customers and holding assets that the Company is not permitted to hold directly. A TRS is subject to federal and state income taxes. The Company did not have any unrecognized tax benefits related to uncertain tax positions as of December 31, 2015 and 2014 . Future amounts of accrued interest and penalties, if any, related to uncertain tax positions will be recorded as a component of income tax expense. The Company does not expect that the amount of unrecognized tax benefits will change significantly in the next 12 months. The Company's material taxing jurisdiction is the U.S. federal jurisdiction; due to the Company's recent formation, the 2015 , 2014 and 2013 tax years are the only periods that remain open to examination by these taxing jurisdictions. Tax years prior to 2012 for the limited partnership and limited liability company that comprise NSA Predecessor are no longer subject to examination. On June 25, 2014, the Company formed NSA TRS, LLC ("NSA TRS"), a Delaware limited liability company. The Company has elected to treat NSA TRS as a TRS, and consequently, NSA TRS is subject to U.S. federal and state corporate income taxes. Deferred tax assets and liabilities are recognized to the extent of any differences between the financial reporting and tax bases of assets and liabilities.
Earnings Per Share and Allocation of Net Income (Loss)	Earnings per Share Basic earnings per share is calculated based on the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated by further adjusting for the dilutive impact using the treasury stock method for any share options and unvested share equivalents outstanding during the period and the if-converted method for any convertible securities outstanding during the period.
Equity-Based Awards	Equity-Based Awards The measurement and recognition of compensation cost for all equity-based awards granted to officers, employees and consultants is based on estimated fair values. Compensation cost is recognized on a straight-line basis over the requisite service periods of each award with non-graded vesting. For awards granted which contain a graded vesting schedule and the only condition for vesting is a service condition, compensation cost is recognized as an expense on a straight-line basis over the requisite service period as if the award was, in substance, a single award. For awards granted for which vesting is subject to a performance condition, including awards that vested upon completion of the Company's initial public offering, compensation cost is recognized over the requisite service period if and when the Company concludes it is probable that the performance condition will be achieved. The estimated fair value of all equity-based awards issued to PROs and their affiliates in connection with self storage property acquisitions is included in the cost of the respective acquisitions. The estimated fair value of such awards is measured at the date the self storage properties are acquired, as this date represents satisfaction of the performance condition and coincides with the award vesting.
Derivatives, Financial Instruments	Derivative Financial Instruments The Company carries all derivative financial instruments on the balance sheet at fair value. Fair value of derivatives is determined by reference to observable prices that are based on inputs not quoted on active markets, but corroborated by market data. The accounting for changes in the fair value of a derivative instrument depends on whether the derivative has been designated and qualifies as part of a hedging relationship. The use of derivative instruments has been limited to interest rate swap and cap agreements. The fair values of derivative instruments are included in other assets and accounts payable and accrued liabilities in the accompanying balance sheets. For derivative instruments not designated as cash flow hedges, the unrealized gains and losses are included in interest expense in the accompanying statements of operations. For derivatives designated as cash flow hedges, the effective portion of the changes in the fair value of the derivatives is initially reported in accumulated other comprehensive loss in our balance sheets and subsequently reclassified into earnings when the hedged transaction affects earnings. The valuation of interest rate swap and cap agreements is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates (forward curves) derived from observable market interest rate forward curves. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.
Fair Value Measurements	Fair Value Measurements When measuring fair value of financial instruments that are required to be recorded or disclosed at fair value, the Company uses a three-tier measurement hierarchy which prioritizes the inputs used to calculate fair value. These tiers include Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.
Segment Reporting	Segment Reporting The Company manages its business as one reportable segment consisting of investments in self storage properties located in the United States. Although we operate in several markets, these operations have been aggregated into one reportable segment based on the similar economic characteristics amongst all markets.
Reclassifications	Reclassifications Certain amounts in the financial statements and related notes have been reclassified to conform to the current year presentation. Such reclassifications do not impact our previously reported financial position or net income (loss).
Allocation of Net Income (Loss)	Allocation of Net Income (Loss) The distribution rights and priorities set forth in our operating partnership's LP Agreement differ from what is reflected by the underlying percentage ownership interests of the unitholders. Accordingly, we allocate GAAP income (loss) utilizing the hypothetical liquidation at book value ("HLBV") method, in which we allocate income or loss based on the change in each unitholders' claim on the net assets of our operating partnership at period end after adjusting for any distributions or contributions made during such period. The HLBV method is commonly applied to equity investments where cash distribution percentages vary at different points in time and are not directly linked to an equity holder's ownership percentage. The HLBV method is a balance sheet-focused approach. A calculation is prepared at each balance sheet date to determine the amount that unitholders would receive if our operating partnership were to liquidate all of its assets (at GAAP net book value) and distribute the resulting proceeds to its creditors and unitholders based on the contractually defined liquidation priorities. The difference between the calculated liquidation distribution amounts at the beginning and the end of the reporting period, after adjusting for capital contributions and distributions, is used to derive each unitholder's share of the income (loss) for the period. Due to the stated liquidation priorities and because the HLBV method incorporates non-cash items such as depreciation expense, in any given period, income or loss may be allocated disproportionately to unitholders as compared to their respective ownership percentage in our operating partnership, and net income (loss) attributable to National Storage Affiliates Trust could be more or less net income than actual cash distributions received and more or less income or loss than what may be received in the event of an actual liquidation. Additionally, the HLBV method could result in net income attributable to National Storage Affiliates Trust during a period when the Company reports a consolidated net loss, or net income attributable to National Storage Affiliates Trust in excess of the Company's consolidated net income.
Other Comprehensive Income (Loss)	Other Comprehensive Income (Loss) The Company has cash flow hedge derivative instruments that are measured at fair value with unrealized gains or losses recognized in other comprehensive income (loss) with a corresponding adjustment to accumulated other comprehensive loss within equity, as discussed further in Note 13. Under the HLBV method of allocating income (loss) discussed above, a calculation is prepared at each balance sheet date by applying the HLBV method including, and excluding, the assets and liabilities resulting from our cash flow hedge derivative instruments to determine comprehensive income (loss) attributable to National Storage Affiliates Trust. As a result of the distribution rights and priorities set forth in our operating partnership's LP Agreement, all amounts of consolidated other comprehensive income (loss) for the year ended December 31, 2015 were allocated to noncontrolling interests, as presented within the accompanying statements of comprehensive income (loss).
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in GAAP when it becomes effective. ASU 2014-09 is effective for the Company on January 1, 2018, with early application permitted for the Company on January 1, 2017. ASU 2014-09 permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis, which modifies the current consolidation guidance. The Company is required to adopt ASU 2015-02 for annual and interim financial statements issued for the year ending December 31, 2016. Upon adoption by the Company, ASU 2015-02 permits the use of either the modified retrospective or cumulative effect transition method. The Company is finalizing its analysis of ASU 2015-02 and does not expect ASU 2015-02 to have a material impact on its consolidated financial statements and related disclosures. In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest, which requires the presentation of debt issuance costs as a direct deduction from the carrying amount of the related debt liabilities. The Company does not expect ASU 2015-03 to have a material impact on the Company's results from operations, however, adoption will result in the reclassification of certain debt issuance costs as an asset and a corresponding reduction in the carrying amount of the Company's debt financings applied retrospectively to all periods. The Company is required to adopt this ASU for annual and interim financial statements issued for the year ending December 31, 2016. In September 2015, the FASB issued ASU 2015-16, Business Combinations—Simplifying the Accounting for Measurement-Period Adjustments, which requires an acquirer of a business to recognize adjustments to provisional amounts that are identified during the business combination's measurement period in the reporting period in which the adjustment amounts are determined rather than retrospectively. ASU 2015-16 is effective for the Company on January 1, 2016, with early application permitted. The Company elected to adopt ASU 2015-16 during the year ended December 31, 2015 and the adoption did not have a material impact on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02, Leases, which amends the existing guidance for accounting for leases, including requiring lessees to recognize most leases on-balance sheet as lease liabilities with corresponding right-of-use assets. ASU 2016-02 is effective for the Company on January 1, 2019, with early application permitted. ASU 2016-02 requires a modified retrospective approach, with entities applying the new guidance at the beginning of the earliest period presented in the financial statements in which they first apply the new standard, with certain elective transition relief. The Company is evaluating the effect that ASU 2016-02 will have on its operating leases, consolidated financial statements and related disclosures.
