Accounting Policies [Abstract]
Description of Business	1	DESCRIPTION OF BUSINESS
	Extra Space Storage Inc. (the “Company”) is a fully integrated, self-administered and self-managed real estate investment trust (“REIT”), formed as a Maryland Corporation on April 30, 2004, to own, operate, manage, acquire, develop and redevelop professionally managed self-storage properties located throughout the United States. The Company continues the business of Extra Space Storage LLC and its subsidiaries, which had engaged in the self-storage business since 1977. The Company’s interest in its stores is held through its operating partnership, Extra Space Storage LP (the “Operating Partnership”), which was formed on May 5, 2004. The Company’s primary assets are general partner and limited partner interests in the Operating Partnership. This structure is commonly referred to as an umbrella partnership REIT, or UPREIT. The Company has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). To the extent the Company continues to qualify as a REIT, it will not be subject to tax, with certain limited exceptions, on the taxable income that is distributed to its stockholders.
	The Company invests in stores by acquiring wholly-owned stores or by acquiring an equity interest in real estate entities. At December 31, 2014, the Company had direct and indirect equity interests in 828 storage facilities. In addition, the Company managed 260 stores for third parties bringing the total number of stores which it owns and/or manages to 1,088. These stores are located in 35 states, Washington, D.C. and Puerto Rico.
	The Company operates in three distinct segments: (1) rental operations; (2) tenant reinsurance; and (3) property management, acquisition and development. The rental operations activities include rental operations of stores in which we have an ownership interest. No single tenant accounts for more than 5.0% of rental income. Tenant reinsurance activities include the reinsurance of risks relating to the loss of goods stored by tenants in the Company’s stores. The Company’s property management, acquisition and development activities include managing, acquiring, developing and selling stores.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	The consolidated financial statements are presented on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of the Company and its wholly- or majority-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
	Variable Interest Entities
	The Company accounts for arrangements that are not controlled through voting or similar rights as variable interest entities (“VIEs”). An enterprise is required to consolidate a VIE if it is the primary beneficiary of the VIE. A VIE is created when (i) the equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support from other parties, or (ii) the entity’s equity holders as a group either: (a) lack the power, through voting or similar rights, to direct the activities of the entity that most significantly impact the entity’s economic performance, (b) are not obligated to absorb expected losses of the entity if they occur, or (c) do not have the right to receive expected residual returns of the entity if they occur. If an entity is deemed to be a VIE, the enterprise that is deemed to have a variable interest, or combination of variable interests, that provides the enterprise with a controlling financial interest in the VIE, is considered the primary beneficiary and must consolidate the VIE.
	The Company has concluded that under certain circumstances when the Company (1) enters into option agreements for the purchase of land or facilities from an entity and pays anon-refundable deposit, or (2) enters into arrangements for the formation of joint ventures, a VIE may be created under condition (i), (ii) (b) or (c) of the previous paragraph. For each VIE created, the Company has performed a qualitative analysis, including considering which party, if any, has the power to direct the activities most significant to the economic performance of each VIE and whether that party has the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE. If the Company is determined to be the primary beneficiary of the VIE, the assets, liabilities and operations of the VIE are consolidated with the Company’s financial statements. Additionally, the Operating Partnership has notes payable to three trusts that are VIEs under condition (ii)(a) above. Since the Operating Partnership is not the primary beneficiary of the trusts, these VIEs are not consolidated.
	The Company’s investments in real estate joint ventures, where the Company has significant influence, but not control, and joint ventures which are VIEs in which the Company is not the primary beneficiary, are recorded under the equity method of accounting on the accompanying consolidated financial statements.
	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.
	Reclassifications
	Certain amounts in the financial statements and supporting note disclosures have been reclassified to conform to the current year presentation. Such reclassifications did not impact previously reported net income or accumulated deficit.
	Fair Value Disclosures
	Derivative financial instruments
	Currently, the Company uses interest rate swaps to manage its interest rate risk. The valuation of these instruments 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 the derivatives, including the period to maturity, and uses observablemarket-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 incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. In conjunction with the Financial Accounting Standard Board’s fair value measurement guidance, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.
	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 its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of December 31, 2014, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.
	The table below presents the Company’s assets and liabilities measured at fair value on a recurring basis as of December 31, 2014, aggregated by the level in the fair value hierarchy within which those measurements fall.
			Fair Value Measurements at Reporting Date Using
	Description		December 31, 2014			Quoted Prices in Active			Significant Other			Significant
						Markets for Identical			Observable Inputs			Unobservable Inputs

	Other liabilities—Cash Flow Hedge Swap Agreements		$	(3,533	)	$	—		$	(3,533	)	$	—
	There were no transfers of assets and liabilities between Level 1 and Level 2 during the year ended December 31, 2014. The Company did not have any significant assets or liabilities that are re-measured on a recurring basis using significant unobservable inputs as of December 31, 2014 or 2013.
	Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
	Long-lived assets held for use are evaluated by the Company for impairment when events or circumstances indicate that there may be impairment. The Company reviews each store at least annually to determine if any such events or circumstances have occurred or exist. The Company focuses on stores where occupancy and/or rental income have decreased by a significant amount. For these stores, the Company determines whether the decrease is temporary or permanent and whether the store will likely recover the lost occupancy and/or revenue in the short term. In addition, the Company reviews stores in the lease-up stage and compares actual operating results to original projections.
	When the Company determines that an event that may indicate impairment has occurred, the Company compares the carrying value of the related long-lived assets to the undiscounted future net operating cash flows attributable to the assets. An impairment loss is recorded if the net carrying value of the assets exceeds the undiscounted future net operating cash flows attributable to the assets. The impairment loss recognized equals the excess of net carrying value over the related fair value of the assets.
	When real estate assets are identified by management as held for sale, the Company discontinues depreciating the assets and estimates the fair value of the assets, net of selling costs. If the estimated fair value, net of selling costs, of the assets that have been identified for sale is less than the net carrying value of the assets, then a valuation allowance is established. The operations of assets held for sale or sold during the period are generally presented as discontinued operations for all periods presented.
	The Company assesses whether there are any indicators that the value of the Company’s investments in unconsolidated real estate ventures may be impaired annually and when events or circumstances indicate that there may be impairment. An investment is impaired if management’s estimate of the fair value of the investment is less than its carrying value. To the extent impairment has occurred, and is considered to be other than temporary, the loss is measured as the excess of the carrying amount of the investment over the fair value of the investment.
	As of December 31, 2014 and 2013, the Company did not have any assets or liabilities measured at fair value on a nonrecurring basis.
	Fair Value of Financial Instruments
	The carrying values of cash and cash equivalents, restricted cash, receivables, other financial instruments included in other assets, accounts payable and accrued expenses, variable-ratenotes payable, lines of credit and other liabilities reflected in the consolidated balance sheets at December 31, 2014 and 2013, approximate fair value.
	The fair values of the Company’s notes receivable from Preferred Operating Partnership unit holders was based on the discounted estimated future cash flow of the notes (categorized within Level 3 of the fair value hierarchy); the discount rate used approximated the current market rate for loans with similar maturities and credit quality. The fair values of the Company’s fixed rate notes payable and notes payable to trusts were estimated using the discounted estimated future cash payments to be made on such debt (categorized within Level 3 of the fair value hierarchy); the discount rates used approximated current market rates for loans, or groups of loans, with similar maturities and credit quality. The fair value of the Company’s exchangeable senior notes was estimated using an average market price for similar securities obtained from a third party.
	The fair values of the Company’s fixed-rate assets and liabilities were as follows for the periods indicated:
			December 31, 2014						December 31, 2013
			Fair			Carrying			Fair			Carrying
			Value			Value			Value			Value
	Notes receivable from Preferred Operating Partnership unit holders		$	126,380		$	120,230		$	103,491		$	100,000
	Fixed rate notes payable and notes payable to trusts		$	1,320,370		$	1,283,893		$	1,365,290		$	1,368,885
	Exchangeable senior notes		$	276,095		$	250,000		$	251,103		$	250,000
	Real Estate Assets
	Real estate assets are stated at cost, less accumulated depreciation. Direct and allowable internal costs associated with the development, construction, renovation, and improvement of real estate assets are capitalized. Interest, property taxes, and other costs associated with development incurred during the construction period are capitalized. The construction period begins when expenditures for the real estate assets have been made and activities that are necessary to prepare the asset for its intended use are in progress. The construction period ends when the asset is substantially complete and ready for its intended use.
	Expenditures for maintenance and repairs are charged to expense as incurred. Major replacements and betterments that improve or extend the life of the asset are capitalized and depreciated over their estimated useful lives. Depreciation is computed using the straight-line method over the estimated useful lives of the buildings and improvements, which are generally between five and 39 years.
	In connection with the Company’s acquisition of stores, the purchase price is allocated to the tangible and intangible assets and liabilities acquired based on their fair values, which are estimated using significant unobservable inputs. The value of the tangible assets, consisting of land and buildings, are determined as if vacant. Intangible assets, which represent the value of existing tenant relationships, are recorded at their fair values based on the avoided cost to replace the current leases. The Company measures the value of tenant relationships based on the rent lost due to the amount of time required to replace existing customers which is based on the Company’s historical experience with turnover in its facilities. Debt assumed as part of an acquisition is recorded at fair value based on current interest rates compared to contractual rates. Acquisition-related transaction costs are expensed as incurred.
	Intangible lease rights represent: (1) purchase price amounts allocated to leases on three stores that cannot be classified as ground or building leases; these rights are amortized to expense over the life of the leases and (2) intangibles related to ground leases on five stores where the leases were assumed by the Company at rates that were lower than the current market rates for similar leases. The values associated with these assumed leases were recorded as intangibles, which will be amortized over the lease terms.
	Investments in Real Estate Ventures
	The Company’s investments in real estate joint ventures, where the Company has significant influence, but not control and joint ventures which are VIEs in which the Company is not the primary beneficiary, are recorded under the equity method of accounting in the accompanying consolidated financial statements.
	Under the equity method, the Company’s investment in real estate ventures is stated at cost and adjusted for the Company’s share of net earnings or losses and reduced by distributions. Equity in earnings of real estate ventures is generally recognized based on the Company’s ownership interest in the earnings of each of the unconsolidated real estate ventures. For the purposes of presentation in the statement of cash flows, the Company follows the “look through” approach for classification of distributions from joint ventures. Under this approach, distributions are reported under operating cash flow unless the facts and circumstances of a specific distribution clearly indicate that it is a return of capital (e.g., a liquidating dividend or distribution of the proceeds from the joint venture’s sale of assets), in which case it is reported as an investing activity.
	Cash and Cash Equivalents
	The Company’s cash is deposited with financial institutions located throughout the United States and at times may exceed federally insured limits. The Company considers all highly liquid debt instruments with a maturity date of three months or less to be cash equivalents.
	Restricted Cash
	Restricted cash is comprised of letters of credit and escrowed funds deposited with financial institutions located throughout the United States relating to earnest money deposits on potential acquisitions, real estate taxes, insurance and capital expenditures.
	Other Assets
	Other assets consist primarily of equipment and fixtures, deferred financing costs, customer accounts receivable, investments in trusts, notes receivable, other intangible assets, income taxes receivable, deferred tax assets, prepaid expenses and the fair value of interest rate swaps. Depreciation of equipment and fixtures is computed on a straight-line basis over three to five years. Deferred financing costs are amortized to interest expense using the effective interest method over the terms of the respective debt agreements.
	Derivative Instruments and Hedging Activities
	The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. 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.
	The Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.
	Risk Management and Use of Financial Instruments
	In the normal course of its ongoing business operations, the Company encounters economic risk. There are three main components of economic risk: interest rate risk, credit risk and market risk. The Company is subject to interest rate risk on its interest-bearing liabilities. Credit risk is the risk of inability or unwillingness of tenants to make contractually required payments. Market risk is the risk of declines in the value of stores due to changes in rental rates, interest rates or other market factors affecting the value of stores held by the Company. The Company has entered into interest rate swap agreements to manage a portion of its interest rate risk.
	Exchange of Common Operating Partnership Units
	Redemption of common Operating Partnership units for shares of common stock, when redeemed under the original provisions of the Operating Partnership agreement, are accounted for by reclassifying the underlying net book value of the units from noncontrolling interest to the Company’s equity. The difference between the fair value of the consideration paid and the adjustment to the carrying amount of the noncontrolling interest is recognized as additional paid in capital for the Company.
	Revenue and Expense Recognition
	Rental revenues are recognized as earned based upon amounts that are currently due from tenants. Leases are generally on month-to-month terms. Prepaid rents are recognized on astraight-line basis over the term of the leases. Promotional discounts are recognized as a reduction to rental income over the promotional period. Late charges, administrative fees, merchandise sales and truck rentals are recognized as income when earned. Management fee revenues are recognized monthly as services are performed and in accordance with the terms of the related management agreements. Equity in earnings of unconsolidated real estate entities is recognized based on our ownership interest in the earnings of each of the unconsolidated real estate entities. Interest income is recognized as earned.
	Property expenses, including utilities, property taxes, repairs and maintenance and other costs to manage the facilities are recognized as incurred. The Company accrues for property tax expense based upon invoice amounts, estimates and historical trends. If these estimates are incorrect, the timing of expense recognition could be affected.
Tenant reinsurance premiums are recognized as revenue over the period of insurance coverage. The Company records an unpaid claims liability at the end of each period based on existing unpaid claims and historical claims payment history. The unpaid claims liability represents an estimate of the ultimate cost to settle all unpaid claims as of each period end, including both reported but unpaid claims and claims that may have been incurred but have not been reported. The Company uses a third party claims administrator to adjust all tenant reinsurance claims received. The administrator evaluates each claim to determine the ultimate claim loss and includes an estimate for claims that may have been incurred but not reported. Annually, a third party actuary evaluates the adequacy of the unpaid claims liability. Prior year claim reserves are adjusted as experience develops or new information becomes known. The impact of such adjustments is included in the current period operations. The unpaid claims liability is not discounted to its present value. Each tenant chooses the amount of insurance coverage they want through the tenant reinsurance program. Tenants can purchase policies in amounts of two thousand dollars to ten thousand dollars of insurance coverage in exchange for a monthly fee. As of December 31, 2014, the average insurance coverage for tenants was approximately $2,540. The Company’s exposure per claim is limited by the maximum amount of coverage chosen by each tenant. The Company purchases reinsurance for losses exceeding a set amount for any one event. The Company does not currently have any amounts recoverable under the reinsurance arrangements.
Real Estate Sales
In general, sales of real estate and related profits/losses are recognized when all consideration has changed hands and risks and rewards of ownership have been transferred. Certain types of continuing involvement preclude sale treatment and related profit recognition; other forms of continuing involvement allow for sale recognition but require deferral of profit recognition.
Advertising Costs
The Company incurs advertising costs primarily attributable to internet, directory and other advertising. These costs are expensed as incurred. The Company recognized $8,370, $6,482, and $6,026 in advertising expense for the years ended December 31, 2014, 2013 and 2012, respectively.
Income Taxes
The Company has elected to be treated as a REIT under Sections 856 through 860 of the Internal Revenue Code. In order to maintain its qualification as a REIT, among other things, the Company is required to distribute at least 90% of its REIT taxable income to its stockholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to federal income tax with respect to that portion of its income which meets certain criteria and is distributed annually to stockholders. The Company plans to continue to operate so that it meets the requirements for taxation as a REIT. Many of these requirements, however, are highly technical and complex. If the Company were to fail to meet these requirements, it would be subject to federal income tax. The Company is subject to certain state and local taxes. Provision for such taxes has been included in income tax expense on the Company’s consolidated statements of operations. For the year ended December 31, 2014, 0.0% (unaudited) of all distributions to stockholders qualified as a return of capital.
The Company has elected to treat its corporate subsidiary, Extra Space Management, Inc. (“ESMI”), as a taxable REIT subsidiary (“TRS”). In general, the Company’s TRS may perform additional services for tenants and may engage in any real estate or non-real estate related business. A TRS is subject to corporate federal income tax. ESM Reinsurance Limited, a wholly-ownedsubsidiary of ESMI, generates income from insurance premiums that are subject to corporate federal income tax and state insurance premiums tax.
Deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities. At December 31, 2014 and 2013, there were no material unrecognized tax benefits. Interest and penalties relating to uncertain tax positions will be recognized in income tax expense when incurred. As of December 31, 2014 and 2013, the Company had no interest or penalties related to uncertain tax provisions.
Stock-Based Compensation
The measurement and recognition of compensation expense for all share-based payment awards to employees and directors are based on estimated fair values. Awards granted are valued at fair value and any compensation element is recognized on a straight line basis over the service periods of each award.
Earnings Per Common Share
Basic earnings per common share is computed using the two-class method by dividing net income attributable to common stockholders by the weighted average number of common shares outstanding during the period. All outstanding unvested restricted stock awards contain rights to non-forfeitable dividends and participate in undistributed earnings with common stockholders; accordingly, they are considered participating securities that are included in the two-class method. Diluted earnings per common share measures the performance of the Company over the reporting period while giving effect to all potential common shares that were dilutive and outstanding during the period. The denominator includes the weighted average number of basic shares and the number of additional common shares that would have been outstanding if the potential common shares that were dilutive had been issued, and is calculated using either the two-class, treasury stock or as if-converted method, whichever is most dilutive. Potential common shares are securities (such as options, convertible debt, Series A Participating Redeemable Preferred Units (“Series A Units”), Series B Redeemable Preferred Units (“Series B Units”), Series C Convertible Redeemable Preferred Units (“Series C Units”), Series D Redeemable Preferred Units (“Series D Units”) and common Operating Partnership units (“OP Units”)) that do not have a current right to participate in earnings of the Company but could do so in the future by virtue of their option, redemption or conversion right.
In computing the dilutive effect of convertible securities, net income is adjusted to add back any changes in earnings in the period associated with the convertible security. The numerator also is adjusted for the effects of any other non-discretionary changes in income or loss that would result from the assumed conversion of those potential common shares. In computing diluted earnings per common share, only potential common shares that are dilutive (those that reduce earnings per common share) are included. For the years ended December 31, 2014, 2013 and 2012, options to purchase approximately 27,374 shares, 44,958 shares and 57,335 shares of common stock, respectively, were excluded from the computation of earnings per share as their effect would have been anti-dilutive. As of December 31, 2014, 764,385 Series B Units, 489,366 Series C Units and 6,492 Series D Units were excluded from the computation of earnings per share as their effect would have been anti-dilutive. As of December 31, 2013, 3,334,956 OP Units, 257,266 Series B Units and 33,302 Series C Units were excluded from the computation of earnings per share as their effect would have been anti-dilutive. As of December 31, 2012, 2,755,650 OP Units were excluded from the computation of earnings per share as their effect would have beenanti-dilutive.
The Company’s Operating Partnership had $250,000 of its 2.375% Exchangeable Senior Notes due 2033 (the “Notes due 2033”) issued and outstanding as of December 31, 2014. The Notes due 2033 could potentially have a dilutive impact on the Company’s earnings per share calculations. The Notes due 2033 are exchangeable by holders into shares of the Company’s common stock under certain circumstances per the terms of the indenture governing the Notes due 2033. The exchange price of the Notes due 2033 was $55.62 per share as of December 31, 2014, and could change over time as described in the indenture. The Company has irrevocably agreed to pay only cash for the accreted principal amount of the Notes due 2033 relative to its exchange obligations, but retained the right to satisfy the exchange obligation in excess of the accreted principal amount in cash and/or common stock. Though the Company has retained that right, Accounting Standards Codification (“ASC”) 260, “Earnings per Share,” requires an assumption that shares would be used to pay the exchange obligation in excess of the accreted principal amount, and requires that those shares be included in the Company’s calculation of weighted average common shares outstanding for the diluted earnings per share computation. For the year ended December 31, 2014, 130,883 shares related to the Notes due 2033 were included in the computation for diluted earnings per share. For the year ended December 31, 2013, no shares related to the Notes due 2033 were included in the computation for diluted earnings per share as the exchange price exceeded the per share price of the Company’s common stock during this period.
For the purposes of computing the diluted impact on earnings per share of the potential exchange of Series A Units for common shares upon redemption, where the Company has the option to redeem in cash or shares and where the Company has stated the positive intent and ability to settle at least $115,000 of the instrument in cash (or net settle a portion of the Series A Units against the related outstanding note receivable), only the amount of the instrument in excess of $115,000 is considered in the calculation of shares contingently issuable for the purposes of computing diluted earnings per share as allowed by ASC 260-10-45-46.
For the purposes of computing the diluted impact on earnings per share of the potential exchange of Series B Units for common shares upon redemption, where the Company has the option to redeem in cash or shares and where the Company has stated the intent and ability to settle the redemption in shares, the Company divided the total value of the Series B Units outstanding as of December 31, 2014 of $41,902 by the closing price of the Company’s common stock as of December 31, 2014 of $58.64 per share. Assuming full exchange for common shares as of December 31, 2014, 714,566 shares would have been issued to the holders of the Series B Units.
For the purposes of computing the diluted impact on earnings per share of the potential exchange of Series C Units into common shares upon redemption, where the Company has the option to redeem in cash or shares and where the Company has stated the intent and ability to settle the redemption in shares, the Company divided the total value of the Series C Units outstanding as of December 31, 2014 of $29,639 by the closing price of the Company’s common stock as of December 31, 2014 of $58.64 per share. Assuming full exchange for common shares as of December 31, 2014, 505,441 shares would have been issued to the holders of the Series C Units.
For the purposes of computing the diluted impact on earnings per share of the potential exchange of Series D Units into common shares upon redemption, where the Company has the option to redeem in cash or shares and where the Company has stated the intent and ability to settle the redemption in shares, the Company divided the total value of the Series D Units outstanding as of December 31, 2014 of $13,710 by the closing price of the Company’s common stock as of December 31, 2014 of $58.64 per share. Assuming full exchange for common shares as of December 31, 2014, 233,795 shares would have been issued to the holders of Series D Units.

Recently Issued Accounting Standards
In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-09, “Revenues from Contracts with Customers” (“ASU 2014-09”). ASU 2014-09 amends the guidance for revenue recognition to replace numerous, industry-specific requirements and converges areas under this topic with those of the International Financial Reporting Standards. ASU 2014-09 outlines a five-step process for customer contract revenue recognition that focuses on transfer of control, as opposed to transfer of risk and rewards. The amendment also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenues and cash flows from contracts with customers. ASU 2014-09 is effective for reporting periods beginning after December 15, 2016, and early adoption is prohibited. Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. Management is currently assessing the impact of the adoption of ASU 2014-09 on the Company’s consolidated financial statements.

Losses on Earnouts from Prior Acquisitions
During 2012, the Company acquired a portfolio of ten stores located in New Jersey and New York. As part of this acquisition, the Company agreed to make an additional cash payment to the sellers if the acquired stores exceeded a specified amount of net rental income two years after the acquisition date. At the acquisition date, the Company believed that it was unlikely that any significant payment would be made as a result of this earnout provision. The rental growth of the stores was significantly higher than expected, resulting in a payment to the sellers of $7,785. This amount is included in gain (loss) on sale of real estate and earnout from prior acquisitions on the Company’s consolidated statements of operations for the year ended December 31, 2014.
During 2011, the Company acquired a store located in Florida. As part of this acquisition, the Company agreed to make an additional cash payment to the sellers if the acquired store exceeded a specified amount of net rental income for any twelve-month period prior to June 30, 2015. At the acquisition date, $133 was recorded as the estimated amount that would be due, and the Company believed that it was unlikely that any significant additional payment would be made as a result of this earnout provision. Because the rental growth of the stores is trending significantly higher than expected, the Company estimated that an additional earnout payment of $2,500 will be due to the seller. This amount is included in gain (loss) on sale of real estate and earnout from prior acquisitions on the Company’s consolidated statements of operations for the year ended December 31, 2014.

	In these joint ventures, the Company and the joint venture partner generally receive a preferred return on their invested capital. To the extent that cash/profits in excess of these preferred returns are generated through operations or capital transactions, the Company would receive a higher percentage of the excess cash/profits than its equity interest.
	In accordance with ASC 810, the Company reviews all of its joint venture relationships quarterly to ensure that there are no entities that require consolidation. As of December 31, 2014, there were no previously unconsolidated entities that were required to be consolidated as a result of this review.
	Between December 2013 and May 2014, the Company acquired twelve stores located in California from entities associated with Grupe Properties Co. Inc. (“Grupe.”) As part of the Grupe acquisition, the Company acquired its joint venture partners’ 60% to 65% equity interests in six stores. The Company previously held the remaining 35% to 40% interests in these stores through six separate joint ventures with Grupe. Prior to the acquisition, the Company accounted for its interests in these joint ventures as equity-method investments. The Company recognized a non-cash gain of $3,438 during the year ended December 31, 2014 as a result of re-measuring the fair value of its equity interest in one of these joint ventures held before the acquisition. During the year ended December 31, 2014, the Company recorded a gain of $584 as a result of the final cash distributions received from the other five joint ventures associated with the acquisitions that were completed during 2013. The Company recognized non-cash gains of $9,339 during the year ended December 31, 2013 as a result of re-measuring its prior equity interests in five joint ventures held before the acquisition.
	On November 1, 2013, the Company acquired its joint venture partner’s 49% interest in HSRE-ESP IA, LLC (“HSRE”), an existing joint venture, for $43,475 in cash and the assumption of a $96,516 loan. The result of this acquisition is that the Company owns a 99% interest in HSRE. The joint venture partner retained a 1% interest, valued at $870, which was recorded at fair value based on the fair value of the assets in the joint venture and is included in other noncontrolling interests on the Company’s consolidated balance sheets. HSRE owns 19 stores in various states. The stores are now consolidated as the Company owns the majority interest in the joint venture. Prior to the acquisition date, the Company accounted for its 50% interest in the joint venture as an equity-method investment. The acquisition date fair value of the previous equity interest was approximately $43,500, and is included as consideration transferred. The Company recognized a non-cash gain of $34,137 as a result of re-measuring its prior equity interest in HSRE held before the acquisition.
	On February 13, 2013, the Company acquired its joint venture partner’s 48% equity interest in Extra Space of Eastern Avenue LLC (“Eastern Avenue”), which owned one store located in Maryland, for approximately $5,979. Prior to the acquisition, the remaining 52% interest was owned by the Company, which accounted for its investment in Eastern Avenue using the equity method. The Company recorded a non-cash gain of $2,215 related to this transaction, which represents the increase in fair value of the Company’s interest in Eastern Avenue from its formation to the acquisition date.
	On February 13, 2013, the Company acquired its joint venture partner’s 61% equity interest in Extra Space of Montrose Avenue LLC (“Montrose”), which owned one store located in Illinois, for approximately $6,878.

The Company recorded a non-cash gain of $341 related to this transaction, which represents the increase in fair value of the Company’s interest in the joint venture from its formation to the acquisition date.
	On December 20, 2012 two joint ventures in which the Company held 20% interests each sold their only self-storage stores. Both stores were located in Illinois. As a result of the sale, the joint ventures were dissolved, and the Company received cash proceeds which resulted in a gain of $1,409.
	On November 30, 2012, the Company completed the acquisition of its joint venture partner’s 80% interest in SPB II, which owned 21 stores located in eleven states. Prior to the acquisition, the remaining 20% interest was owned by the Company, which accounted for its investment in SPB II using the equity method. Subsequent to the acquisition, the Company had full ownership. GAAP requires an entity that completes a business combination in stages to re-measure its previously held equity interest in the acquiree at its acquisition date fair value and recognize the resulting gain or loss, if any, in earnings. The Company recorded a gain of $10,171 related to this transaction, which represents the increase in fair value of the Company’s 20% interest in SPB II from the time the Company purchased its interest in the joint venture to the acquisition date.
	On July 2, 2012, the Company completed the acquisition of PREI®’s 94.9% interest in PRISA III, which was formed in 2005 and owned 36 stores located in 18 states. Prior to the acquisition, the remaining 5.1% interest was owned by the Company, which accounted for its investment in PRISA III using the equity method. Subsequent to the acquisition, the Company had full ownership. GAAP requires an entity that completes a business combination in stages to re-measure its previously held equity interest in the acquiree at its acquisition date fair value and recognize the resulting gain or loss, if any, in earnings. The Company recorded a gain of $13,499 related to this transaction, which represents the increase in fair value of the Company’s 5.1% interest in PRISA III from the formation of the joint venture to the acquisition date.
	On February 17, 2012, a joint venture in which the Company held a 40% equity interest sold its only store. The store was located in New York. As a result of the sale, the joint venture was dissolved, and the Company received cash proceeds which resulted in a gain of $5,550.
	On January 15, 2012, the Company sold its 40% equity interest in U-Storage de Mexico S.A. and related entities to its joint venture partners for $4,841.

Variable Interests in Unconsolidated Real Estate Joint Ventures:
The Company has an interest in one unconsolidated joint venture with an unrelated third party which is a variable interest entity (“VIE”). The Company holds an 18% equity interest and a 50% profit interest in the VIE joint venture (“VIE JV”), and has 50% of the voting rights in the VIE JV. Qualification as a VIE was based on the determination that the equity investment at risk for the joint venture was not sufficient based on a qualitative and quantitative analysis performed by the Company. The Company performed a qualitative analysis for the joint venture to determine which party was the primary beneficiary of each VIE. The Company determined that since the powers to direct the activities most significant to the economic performance of the entity is shared equally by the Company and its joint venture partner, there is no primary beneficiary. Accordingly, the interest is recorded using the equity method.
The VIE JV owns a single store. This joint venture is financed through a combination of (1) equity contributions from the Company and its joint venture partner and (2) amounts payable to the Company. The amounts payable to the Company consist of amounts owed for expenses paid on behalf of the joint venture by the Company as manager and mortgage notes payable to the Company. The Company performs management services for the VIE JV in exchange for a management fee of approximately 6.0% of cash collected by the store. The Company completed the purchase of the VIE JV’s mortgage loan on April 3, 2014. The mortgage notes payable were in default as of December 31, 2014. Except as disclosed, the Company has not provided financial or other support during the periods presented to the VIE JV that it was not previously contractually obligated to provide.
The Company’s maximum exposure to loss for this joint venture as of December 31, 2014, is the total of the amounts payable to the Company and the Company’s investment balances in the joint venture. The Company believes that the risk of incurring a material loss as a result of having to perform on the loan guarantee is unlikely and, therefore, no liability has been recorded related to this guarantee. Also, repossessing and/or selling the store and land that collateralize the amounts payable to the Company could provide funds sufficient to reimburse the Company.
The following table compares the liability balance and the maximum exposure to loss related to the Company’s VIE JV as of December 31, 2014:
		Liability			Investment			Amounts			Maximum		Difference
		Balance			Balance			Payable to the			Exposure
								Company			to Loss
Extra Space of Sacramento One LLC		$	—		$	(1,264	)	$	10,590		$	9,326	$	(9,326	)
The Company had no consolidated VIEs for the year ended December 31, 2014.

Under the credit facility, the Company has agreed to fund a series of loans to a variety of the partner’s subsidiaries, with a total not exceeding $100,000. The loans will be secured by mortgages of stores that are subject to approval by the Company. The loans are expected to close over the next three years, will bear interest at Libor plus 2.55%, and have terms of five years each. The closing of each loan is intended to be accompanied by a simultaneous put/call option agreement, under which the partner’s subsidiaries can require the Company to buy the store, and whereby the Company can require the partner’s subsidiaries to sell the stores. No amounts have been drawn on this credit facility as of December 31, 2014.

DERIVATIVES

The Company is exposed to certain risk arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources and duration of its debt funding and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s investments and borrowings.

Cash Flow Hedges of Interest Rate Risk

The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive deficit and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. A portion of these changes is excluded from accumulated other comprehensive income as it is allocated to noncontrolling interests. During the years ended December 31, 2014, 2013 and 2012, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt. During 2015, the Company estimates that an additional $7,417 will be reclassified as an increase to interest expense.

The following table summarizes the terms of the Company’s 19 derivative financial instruments, which have a total combined notional amount of $717,353, as of December 31, 2014:

Credit-Risk-Related Contingent Features

The Company has agreements with some of its derivative counterparties that contain provisions pursuant to which, the Company could be declared in default of its derivative obligations if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender.

The Company also has an agreement with some of its derivative counterparties that incorporates the loan covenant provisions of the Company’s indebtedness with a lender affiliate of the derivative counterparty. Failure to comply with the loan covenant provisions would result in the Company being in default on any derivative instrument obligations covered by the agreement.

As of December 31, 2014, the fair value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $3,532. As of December 31, 2014, the Company had not posted any collateral related to these agreements. If the Company had breached any of these provisions as of December 31, 2014, it could have been required to settle its obligations under the agreements at their termination value of $3,757.

Equity [Abstract]
Notes Payable to Trusts	9	NOTES PAYABLE TO TRUSTS
	During July 2005, ESS Statutory Trust III (the “Trust III”), a newly formed Delaware statutory trust and a wholly-owned, unconsolidated subsidiary of the Operating Partnership, issued an aggregate of $40,000 of preferred securities which mature on July 31, 2035. In addition, the Trust III issued 1,238 of Trust common securities to the Operating Partnership for a purchase price of $1,238. On July 27, 2005, the proceeds from the sale of the preferred and common securities of $41,238 were loaned in the form of a note to the Operating Partnership (“Note 3”). Note 3 had a fixed rate of 6.91% through July 31, 2010, and then was payable at a variable rate equal to the three-month LIBOR plus 2.40% per annum. Effective July 11, 2011, the Trust III entered into an interest rate swap that fixes the interest rate to be paid at 4.99% per annum and matures July 11, 2018. The interest on Note 3, payable quarterly, will be used by the Trust III to pay dividends on the trust preferred securities. The trust preferred securities became redeemable by the Trust III with no prepayment premium on July 27, 2010.
	During May 2005, ESS Statutory Trust II (the “Trust II”), a newly formed Delaware statutory trust and a wholly-owned, unconsolidated subsidiary of the Operating Partnership of the Company, issued an aggregate of $41,000 of preferred securities which mature on June 30, 2035. In addition, the Trust II issued 1,269 of Trust common securities to the Operating Partnership for a purchase price of $1,269. On May 24, 2005, the proceeds from the sale of the preferred and common securities of $42,269 were loaned in the form of a note to the Operating Partnership (“Note 2”). Note 2 had a fixed rate of 6.67% through June 30, 2010, and then was payable at a variable rate equal to the three-month LIBOR plus 2.40% per annum. Effective July 11, 2011, the Trust II entered into an interest rate swap that fixes the interest rate to be paid at 4.99% per annum and matures July 11, 2018. The interest on Note 2, payable quarterly, will be used by the Trust II to pay dividends on the trust preferred securities. The trust preferred securities became redeemable by the Trust II with no prepayment premium on June 30, 2010.
	During April 2005, ESS Statutory Trust I (the “Trust”), a newly formed Delaware statutory trust and a wholly-owned, unconsolidated subsidiary of the Operating Partnership of the Company issued an aggregate of $35,000 of trust preferred securities which mature on June 30, 2035. In addition, the Trust issued 1,083 of Trust common securities to the Operating Partnership for a purchase price of $1,083. On April 8, 2005, the proceeds from the sale of the trust preferred and common securities of $36,083 were loaned in the form of a note to the Operating Partnership (the “Note”). The Note has a variable rate equal to the three-month LIBOR plus 2.25% per annum. Effective June 30, 2010, the Trust entered into an interest rate swap that fixes the interest rate to be paid at 5.14% per annum and matures on June 30, 2018. The interest on the Note, payable quarterly, will be used by the Trust to pay dividends on the trust preferred securities. The trust preferred securities are redeemable by the Trust with no prepayment premium.
	Trust, Trust II and Trust III (together, the “Trusts”) are VIEs because the holders of the equity investment at risk (the trust preferred securities) do not have the power to direct the activities of the entities that most significantly affect the entities’ economic performance because of their lack of voting or similar rights. Because the Operating Partnership’s investment in the Trusts’ common securities was financed directly by the Trusts as a result of its loan of the proceeds to the Operating Partnership, that investment is not considered to be an equity investment at risk. The Operating Partnership’s investment in the Trusts is not a variable interest because equity interests are variable interests only to the extent that the investment is considered to be at risk, and therefore the Operating Partnership cannot be the primary beneficiary of the Trusts. Since the Company is not the primary beneficiary of the Trusts, they have not been consolidated. A debt obligation has been recorded in the form of notes as discussed above for the proceeds, which are owed to the Trusts by the Company. The Company has also recorded its investment in the Trusts’ common securities as other assets.
	The Company has not provided financing or other support during the periods presented to the Trusts that it was not previously contractually obligated to provide. The Company’s maximum exposure to loss as a result of its involvement with the Trusts is equal to the total amount of the notes discussed above less the amounts of the Company’s investments in the Trusts’ common securities. The net amount is the notes payable that the Trusts owe to third parties for their investments in the Trusts’ preferred securities.
	Following is a tabular comparison of the liabilities the Company has recorded as a result of its involvements with the Trusts to the maximum exposure to loss the Company is subject to related to the Trusts as of December 31, 2014:

Exchangeable Senior Notes	10	EXCHANGEABLE SENIOR NOTES
	On June 21, 2013, the Operating Partnership issued $250,000 of its 2.375% Exchangeable Senior Notes due 2033 at a 1.5% discount, or $3,750. Costs incurred to issue the Notes due 2033 were approximately $1,672. These costs are being amortized as an adjustment to interest expense over five years, which represents the estimated term based on the first available redemption date, and are included in other assets in the consolidated balance sheet. The Notes due 2033 are general unsecured senior obligations of the Operating Partnership and are fully guaranteed by the Company. Interest is payable on January 1 and July 1 of each year beginning January 1, 2014, until the maturity date of July 1, 2033. The Notes due 2033 bear interest at 2.375% per annum and contain an exchange settlement feature, which provides that the Notes due 2033 may, under certain circumstances, be exchangeable for cash (for the principal amount of the Notes due 2033) and, with respect to any excess exchange value, for cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock at the Company’s option. The initial exchange rate of the Notes due 2033 is approximately 17.98 shares of the Company’s common stock per $1,000 principal amount of the Notes due 2033.
	The Operating Partnership may redeem the Notes due 2033 at any time to preserve the Company’s status as a REIT. In addition, on or after July 5, 2018, the Operating Partnership may redeem the Notes due 2033 for cash, in whole or in part, at 100% of the principal amount plus accrued and unpaid interest, upon at least 30 days but not more than 60 days prior written notice to the holders of the Notes due 2033. The holders of the Notes due 2033 have the right to require the Operating Partnership to repurchase the Notes due 2033 for cash, in whole or in part, on July 1 of the years 2018, 2023, and 2028, and upon the occurrence of certain designated events, in each case for a repurchase price equal to 100% of the principal amount of the Notes due 2033 plus accrued and unpaid interest. Certain events are considered “Events of Default,” as defined in the indenture governing the Notes due 2033, which may result in the accelerated maturity of the Notes due 2033.
	GAAP requires entities with convertible debt instruments that may be settled entirely or partially in cash upon conversion to separately account for the liability and equity components of the instrument in a manner that reflects the issuer’s economic interest cost. The Company therefore accounts for the liability and equity components of the Notes due 2033 separately. The equity component is included in paid-in capital in stockholders’ equity in the consolidated balance sheet, and the value of the equity component is treated as original issue discount for purposes of accounting for the debt component. The discount is being amortized as interest expense over the remaining period of the debt through its first redemption date, July 1, 2018. The effective interest rate on the liability component is 4.0%.
	Information about the carrying amount of the equity component, the principal amount of the liability component, its unamortized discount and its net carrying amount were as follows for the periods indicated:
			December 30, 2014			December 31, 2013
	Carrying amount of equity component		$	14,496		$	14,496

	Net carrying amount of liability component		$	236,946		$	233,513
	On March 27, 2007, the Company’s Operating Partnership issued $250,000 of 3.625% Exchangeable Senior Notes due 2027. The Notes due 2027 bore interest at 3.625% per annum and contained an exchange settlement feature, which provided that under certain circumstances, the Notes due 2027 could have been exchanged for cash (up to the principal amount) and, with respect to any excess exchange value, for cash, shares of the Company’s common stock, or a combination of cash and shares of the Company’s common stock at the option of the Operating Partnership. The Company accounted for the liability and equity components of the Notes due 2027 separately as required under GAAP. The effective interest rate on the liability component of the Notes due 2027 was 5.75%.
	On March 1, 2012, the Company announced that the holders of the Operating Partnership’s then-outstanding $87,663 principal amount of the Notes due 2027 had the right to surrender their notes for repurchase by the Operating Partnership on April 1, 2012 for 100% of the principal amount, pursuant to the holders’ rights under the indenture governing the Notes due 2027.
	As of April 3, 2012, the Company received notice that the holders of the entire $87,663 principal amount of the Notes due 2027 had surrendered their notes for exchange. On April 26, 2012, the Company settled the exchange by paying cash for the principal amount, as required by the indenture, and issuing 684,685 shares of common stock for the value in excess of the principal amount. The issuance of shares was reflected as an increase in paid-in-capital with a corresponding decrease in paid-in-capital attributable to the reacquisition of the equity component of the convertible debt.
	The amount of interest cost recognized relating to the contractual interest rate and the amortization of the discount on the liability component for the Notes due 2033 and the Notes due 2027 was as follows for the periods presented:

Related Party and Affiliated Real Estate Joint Venture Transactions	13	RELATED PARTY AND AFFILIATED REAL ESTATE JOINT VENTURE TRANSACTIONS
	The Company provides management services to certain joint ventures, third parties and other related party stores. Management agreements provide generally for management fees of 6.0% of cash collected from total revenues for the management of operations at the stores. In addition, the Company receives an asset management fee equal to 50 basis points multiplied by the total asset value of the stores owned by the SPI joint venture, provided certain requirements are met.

	Centershift, a related party service provider, was partially owned by one of the Company’s board members, whose interest was sold in February 2014. Effective January 1, 2004, the Company entered into a license agreement with Centershift which secured a perpetual right for continued use of STORE (the site management software used at all sites operated by the Company) in all aspects of the Company’s property acquisition, development, redevelopment and operational activities. On October 1, 2013, the Company bought out the remainder of its three year contract with Centershift for $1,500, which was included in general and administrative expense for the year ended December 31, 2013. In addition, during the year ended December 31, 2013, the Company purchased a copy of the STORE source code and some equipment from Centershift for $2,600. Subsequent to these purchases, the Company no longer has any contractual liability to Centershift. During the years ended December 31, 2014, 2013 and 2012, the Company paid Centershift $0, $1,095 and $1,235, respectively, relating to the purchase of software and license agreements.

Noncontrolling_Interests

Noncontrolling Interests	12 Months Ended
	Dec. 31, 2014
Noncontrolling Interests	17	OTHER NONCONTROLLING INTERESTS
	Other noncontrolling interests represent the ownership interests of various third parties in two consolidated joint ventures as of December 31, 2014. One of these consolidated joint ventures owns one store which was under construction at December 31, 2014. The second consolidated joint venture owns 19 stores. The ownership interests of the third party owners range from 1.0% to 3.3%. Other noncontrolling interests are included in the stockholders’ equity section of the Company’s consolidated balance sheet. The income or losses attributable to these third party owners based on their ownership percentages are reflected in net income allocated to the Operating Partnership and other noncontrolling interests in the consolidated statement of operations.
	In November 2013, the Company purchased its joint venture partner’s 10% membership interest in an existing joint venture for $1,292. The joint venture owned a single store located in California, and as a result of the acquisition, the store became wholly-owned by the Company. Since the Company retained its controlling financial interest in the subsidiary, this transaction was accounted for as an equity transaction. The carrying amount of the noncontrolling interest was reduced to zero to reflect the purchase, and the difference between the price paid by the Company and the adjustment to the carrying value of the noncontrolling interest was recorded as an adjustment to equity attributable to the parent.
	In May 2013, the Company purchased one of its joint venture partner’s 27.6% capital interest and 35% profit interest in a previously unconsolidated joint venture for $950. The partner’s interest was reported in other noncontrolling interests prior to the purchase. As a result of the acquisition, the store became wholly-owned by the Company. Since the Company retained its controlling financial interest in the subsidiary, this transaction was accounted for as an equity transaction. The carrying amount of the noncontrolling interest was reduced to zero to reflect the purchase and the difference between the price paid by the Company and the carrying value of the noncontrolling interest was recorded as an adjustment to equity attributable to the parent.
	In February 2013, the Company purchased one of its joint venture partner’s 1.7% capital interest and 17% profit interest in a consolidated store for $200. As a result, the Company’s capital interest percentage in this joint venture increased from 95% to 96.7%. Since the Company retained its controlling financial interest in the subsidiary, this transaction was accounted for as an equity transaction. The carrying amount of the noncontrolling interest was reduced to reflect the purchase and the difference between the price paid by the Company and the adjustment to the carrying value of the noncontrolling interest was recorded as an adjustment to equity attributable to the parent.
Preferred Operating Partnership Units [Member]
Noncontrolling Interests	15	NONCONTROLLING INTEREST REPRESENTED BY PREFERRED OPERATING PARTNERSHIP UNITS
	Classification of Noncontrolling Interests
	GAAP requires a company to present ownership interests in subsidiaries held by parties other than the company in the consolidated financial statements within the equity section, but separate from the company’s equity. It also requires the amount of consolidated net income attributable to the parent and to the noncontrolling interest to be clearly identified and presented on the face of the consolidated statement of operations and requires changes in ownership interest to be accounted for similarly as equity transactions. If noncontrolling interests are determined to be redeemable, they are to be carried at their redemption value as of the balance sheet date and reported as temporary equity.
	The Company has evaluated the terms of the Operating Partnership’s preferred units and classifies the noncontrolling interest represented by such preferred units as stockholders’ equity in the accompanying consolidated balance sheets. The Company will periodically evaluate individual noncontrolling interests for the ability to continue to recognize the noncontrolling amount as permanent equity in the consolidated balance sheets. Any noncontrolling interests that fail to qualify as permanent equity will be reclassified as temporary equity and adjusted to the greater of (1) the carrying amount, or (2) its redemption value as of the end of the period in which the determination is made.
	Series A Participating Redeemable Preferred Units
	On June 15, 2007, the Operating Partnership entered into a Contribution Agreement with various limited partnerships affiliated with AAAAA Rent-A-Space to acquire ten stores in exchange for 989,980 Series A Units. The stores are located in California and Hawaii.
	On June 25, 2007, the Operating Partnership loaned the holders of the Series A Units $100,000. The note receivable bears interest at 4.85%. During 2013, a loan amendment was signed extending the maturity date to September 1, 2020. The loan is secured by the borrower’s Series A Units. The holders of the Series A Units could redeem up to 114,500 Series A Units prior to the maturity date of the loan. If any redemption in excess of 114,500 Series A Units occurs prior to the maturity date, the holder of the Series A Units is required to repay the loan as of the date of that redemption. On October 3, 2014, the holders of the Series A Units redeemed 114,500 Series A Units for $4,794 in cash and 280,331 shares of common stock. No additional redemption of Series A Units can be made without repayment of the loan. The Series A Units are shown on the balance sheet net of the $100,000 loan because the borrower under the loan receivable is also the holder of the Series A Units.
	The partnership agreement of the Operating Partnership (as amended, the “Partnership Agreement”) provides for the designation and issuance of the Series A Units. The Series A Units have priority over all other partnership interests of the Operating Partnership with respect to distributions and liquidation.
	Under the Partnership Agreement, Series A Units in the amount of $115,000 bear a fixed priority return of 5.0% and have a fixed liquidation value of $115,000. The remaining balance participates in distributions with, and has a liquidation value equal to, that of the common OP Units. The Series A Units became redeemable at the option of the holder on September 1, 2008, which redemption obligation may be satisfied, at the Company’s option, in cash or shares of its common stock.
	Series B Redeemable Preferred Units
	On April 3, 2014, the Operating Partnership completed the purchase of a store located in Georgia. This store was acquired in exchange for $15,158 of cash and 333,360 Series B Units valued at $8,334.
	On August 29, 2013, the Operating Partnership completed the purchase of 19 out of 20 stores affiliated with All Aboard Mini Storage, all of which are located in California. On September 26, 2013, the Operating Partnership completed the purchase of the remaining facility. These stores were acquired in exchange for $100,876 in cash (including $98,960 of debt assumed and immediately defeased at closing), 1,342,727 Series B Units valued at $33,568, and 1,448,108 common OP Units valued at $62,341.
	The Partnership Agreement provides for the designation and issuance of the Series B Units. The Series B Units rank junior to the Series A Units, on parity with the Series C Units and Series D Units, and senior to all other partnership interests of the Operating Partnership with respect to distributions and liquidation.
	The Series B Units have a liquidation value of $25.00 per unit for a fixed liquidation value of $41,902. Holders of the Series B Units receive distributions at an annual rate of 6.0%. These distributions are cumulative. The Series B Units are redeemable at the option of the holder on the first anniversary of the date of issuance, which redemption obligations may be satisfied at the Company’s option in cash or shares of its common stock.
	Series C Convertible Redeemable Preferred Units
	On November 19, 2013, the Operating Partnership entered into Contribution Agreements with various entities affiliated with Grupe, under which the Company agreed to acquire twelve stores, all of which are located in California. The Company completed the purchase of these self-storage stores between December 2013 and May 2014. The Company previously held a 35% interest in five of these stores and a 40% interest in one store through six separate joint ventures with Grupe. These stores were acquired in exchange for a total of approximately $45,722 of cash, the assumption of $37,532 in existing debt, and the issuance of 704,016 Series C Units valued at $30,960.
	The Partnership Agreement provides for the designation and issuance of the Series C Units. The Series C Units rank junior to the Series A Units, on parity with the Series B Units and Series D Units, and senior to all other partnership interests of the Operating Partnership with respect to distributions and liquidation.
	The Series C Units have a liquidation value of $42.10 per unit. From issuance to the fifth anniversary of issuance, each Series C Unit holder will receive quarterly distributions equal to the quarterly distribution for common OP Unit plus $0.18. Beginning on the fifth anniversary of issuance, each Series C Unit holder will receive a fixed quarterly distribution equal to the aggregate quarterly distribution payable in respect of such Series C Unit during the four quarters immediately preceding the fifth anniversary of issuance divided by four. These distributions are cumulative. The Series C Units will become redeemable at the option of the holder one year from the date of issuance, which redemption obligation may be satisfied at the Company’s option in cash or shares of its common stock. The Series C Units will also become convertible into common OP Units at the option of the holder one year from the date of issuance, at a rate of 0.9145 common OP Units per Series C Unit converted. This conversion option expires upon the fifth anniversary of the date of issuance.
	In December 2014, the Operating Partnership loaned holders of the Series C Units $20,230. The notes receivable, which are collateralized by the Series C Units, bear interest at 5.0% and mature on December 15, 2024. The Series C Units are shown on the balance sheet net of the $20,230 loan because the borrower under the loan receivable is also the holder of the Series C units.
	Series D Redeemable Preferred Units
	In December 2014, the Operating Partnership completed the acquisition of a store located in Florida. This store was acquired in exchange for $5,621 in cash and 548,390 Series D Units valued at $13,710.
	The Partnership Agreement provides for the designation and issuance of the Series D Units. The Series D Units rank junior to the Series A Units, on parity with the Series B Units and Series C Units, and senior to all other partnership interest of the Operating Partnership with respect to distributions and liquidation.
	The Series D Units have a liquidation value of $25.00 per unit, for a fixed liquidation value of $13,710. Holders of the Series D Units receive distributions at an annual rate of 5.0%. These distributions are cumulative. The Series D Units will become redeemable at the option of the holder on the first anniversary of the date of issuance, which redemption obligation may be satisfied at the Company’s option in cash or shares of its common stock.
Common Operating Partnership [Member]
Noncontrolling Interests	16	NONCONTROLLING INTEREST IN OPERATING PARTNERSHIP
	The Company’s interest in its stores is held through the Operating Partnership. ESS Holding Business Trust I, a wholly-owned subsidiary of the Company, is the sole general partner of the Operating Partnership. ESS Business Trust II, also a wholly-owned subsidiary of the Company, is a limited partner of the Operating Partnership. Between its general partner and limited partner interests, the Company held a 93.4% majority ownership interest therein as of December 31, 2014. The remaining ownership interests in the Operating Partnership (including Preferred Operating Partnership units) of 6.6% are held by certain former owners of assets acquired by the Operating Partnership. As of December 31, 2014, the Operating Partnership had 4,365,879 OP Units outstanding.
	The noncontrolling interest in the Operating Partnership represents OP Units that are not owned by the Company. In conjunction with the formation of the Company and as a result of subsequent acquisitions, certain persons and entities contributing interests in stores to the Operating Partnership received limited partnership units in the form of OP units. Limited partners who received OP Units in the formation transactions or in exchange for contributions for interests in stores have the right to require the Operating Partnership to redeem part or all of their OP Units for cash based upon the fair market value of an equivalent number of shares of the Company’s common stock (10 day average) at the time of the redemption. Alternatively, the Company may, at its sole discretion, elect to acquire those OP Units in exchange for shares of its common stock on a one-for-one basis, subject to anti-dilution adjustments provided in the Operating Partnership agreement. The ten day average closing stock price at December 31, 2014, was $59.26 and there were 4,365,879 OP Units outstanding. Assuming that all of the unit holders exercised their right to redeem all of their OP Units on December 31, 2014 and the Company elected to pay the non-controlling members cash, the Company would have paid $258,722 in cash consideration to redeem the units.
	In December 2014, the Company purchased a single store in California. As part of the consideration, 50,620 OP Units were issued for a value of $2,983.
	In October 2014, 6,859 OP units were redeemed in exchange for the Company’s common stock. In December 2014, 12,000 OP units were redeemed in exchange for the Company’s common stock.
	In October 2013, 12,500 OP Units were redeemed in exchange for the Company’s common stock. In March and April 2013, 1,000 OP Units were redeemed in exchange for $41 in cash.
	On August 29, 2013 and September 26, 2013, the Company purchased 20 stores in California. As part of the consideration, 1,448,108 OP Units were issued for a value of $62,341.
	In December 2012, 304,817 OP Units were redeemed in exchange for the Company’s common stock. In April 2012, 5,475 OP Units were redeemed for $155 in cash.
	GAAP requires a company to present ownership interests in subsidiaries held by parties other than the company in the consolidated financial statements within the equity section but separate from the company’s equity. It also requires the amount of consolidated net income attributable to the parent and to the noncontrolling interest to be clearly identified and presented on the face of the consolidated statement of operations and requires changes in ownership interest to be accounted for similarly as equity transactions. If noncontrolling interests are determined to be redeemable, they are to be carried at their redemption value as of the balance sheet date and reported as temporary equity.
	The Company has evaluated the terms of the common OP Units and classifies the noncontrolling interest represented by the common OP Units as stockholders’ equity in the accompanying consolidated balance sheets. The Company will periodically evaluate individual noncontrolling interests for the ability to continue to recognize the noncontrolling amount as permanent equity in the consolidated balance sheets. Any noncontrolling interests that fail to qualify as permanent equity will be reclassified as temporary equity and adjusted to the greater of (1) the carrying amount, or (2) its redemption value as of the end of the period in which the determination is made.

Stock-Based Compensation	12 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	18	STOCK-BASED COMPENSATION
	The Company has the following plans under which shares were available for grant at December 31, 2014:
		•		The 2004 Long-Term Incentive Compensation Plan as amended and restated, and
		•		The 2004 Non-Employee Directors’ Share Plan (together, the “Plans”).
	Option grants are issued with an exercise price equal to the closing price of stock on the date of grant. Unless otherwise determined by the Compensation, Nominating and Governance Committee (“CNG Committee”) at the time of grant, options shall vest ratably over a four-year period beginning on the date of grant. Each option will be exercisable once it has vested. Options are exercisable at such times and subject to such terms as determined by the CNG Committee, but under no circumstances may be exercised if such exercise would cause a violation of the ownership limit in the Company’s charter. Options expire 10 years from the date of grant.
	Also as defined under the terms of the Plans, restricted stock grants may be awarded. The stock grants are subject to a vesting period over which the restrictions are released and the stock certificates are given to the grantee. During the performance or vesting period, the grantee is not permitted to sell, transfer, pledge, encumber or assign shares of restricted stock granted under the Plans; however, the grantee has the ability to vote the shares and receive nonforfeitable dividends paid on shares. Unless otherwise determined by the CNG Committee at the time of grant, the forfeiture and transfer restrictions on the shares lapse over a four-year period beginning on the date of grant.
	As of December 31, 2014, 2,270,790 shares were available for issuance under the Plans.
	Option Grants
	A summary of stock option activity is as follows:
	Options		Number of Shares			Weighted Average			Weighted Average			Aggregate Intrinsic

	Vested and Expected to Vest			563,432		$	16.4			4.73		$	23,798
	Ending Exercisable			457,131		$	12.26			4.03		$	21,204
	The aggregate intrinsic value in the table above represents the total value (the difference between the Company’s closing stock price on the last trading day of 2014 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on December 31, 2014. The amount of aggregate intrinsic value will change based on the fair market value of the Company’s stock.
	The weighted average fair value of stock options granted in 2014, 2013 and 2012, was $12.03, $9.74 and $6.64, respectively. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions:
			For the Year Ended December 31,
			2014			2013			2012
	Expected volatility			40	%		42	%		44	%
	Dividend yield			4	%		4	%		5	%
	Risk-free interest rate			1.5	%		0.9	%		0.9	%
	Average expected term (years)			5			5			5
	The Black-Scholes model incorporates assumptions to value stock-based awards. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of the grant for the estimated life of the option. The Company uses actual historical data to calculate the expected price volatility, dividend yield and average expected term. The forfeiture rate, which is estimated at a weighted-average of 5.0% of unvested options outstanding as of December 31, 2014, is adjusted periodically based on the extent to which actual forfeitures differ, or are expected to differ, from the previous estimates.
	A summary of stock options outstanding and exercisable as of December 31, 2014, is as follows:
			Options Outstanding									Options Exercisable
	Exercise Price		Shares			Weighted Average			Weighted Average			Shares		Weighted Average
						Remaining			Exercise Price					Exercise Price
						Contractual Life
	$6.22—$6.22			174,765			4.13		$	6.22			174,765	$	6.22
	$11.59—$12.85			113,910			4.96			12.07			113,910		12.07
	$13.04—$16.83			118,750			2.22			15.24			118,750		15.24
	$19.60—$38.40			132,552			6.83			28.78			48,956		26.47
	$47.50—$47.50			28,750			8.9			47.5			750		47.5
	$6.22—$47.50			568,727			4.77		$	16.62			457,131	$	12.26
	The Company recorded compensation expense relating to outstanding options of $456, $536 and $585 in general and administrative expense for the years ended December 31, 2014, 2013 and 2012, respectively. Total cash received for the years ended December 31, 2014, 2013 and 2012, related to option exercises was $3,095, $5,896 and $10,267, respectively. At December 31, 2014, there was $585 of total unrecognized compensation expense related to non-vested stock options under the Company’s 2004 Long-Term Incentive Compensation Plan. That cost is expected to be recognized over a weighted-average period of 1.79 years. The valuation model applied in this calculation utilizes subjective assumptions that could potentially change over time, including the expected forfeiture rate. Therefore, the amount of unrecognized compensation expense at December 31, 2014, noted above does not necessarily represent the expense that will ultimately be realized by the Company in the statement of operations.
	Common Stock Granted to Employees and Directors
	The Company recorded $4,528, $4,283 and $3,771 of expense in general and administrative expense in its statement of operations related to outstanding shares of common stock granted to employees and directors for the years ended December 31, 2014, 2013 and 2012, respectively. The forfeiture rate, which is estimated at a weighted-average of 10.21% of unvested awards outstanding as of December 31, 2014, is adjusted periodically based on the extent to which actual forfeitures differ, or are expected to differ, from the previous estimates. At December 31, 2014 there was $7,010 of total unrecognized compensation expense related to non-vested restricted stock awards under the Company’s 2004 Long-Term Incentive Compensation Plan. That cost is expected to be recognized over a weighted-average period of 2.09 years.
	The fair value of common stock awards is determined based on the closing trading price of the Company’s common stock on the grant date.
	A summary of the Company’s employee and director share grant activity is as follows:

Income Taxes	20	INCOME TAXES
	As a REIT, the Company is generally not subject to federal income tax with respect to that portion of its income which is distributed annually to its stockholders. However, the Company has elected to treat one of its corporate subsidiaries, Extra Space Management, Inc., as a taxable REIT subsidiary. In general, the Company’s TRS may perform additional services for tenants and generally may engage in any real estate or non-real estate related business. A TRS is subject to corporate federal income tax. The Company accounts for income taxes in accordance with the provisions of ASC 740, “Income Taxes.” Deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities. The Company has elected to use the Tax-Law-Ordering approach to determine when excess tax benefits will be realized.
	The income tax provision for the years ended December 31, 2014, 2013 and 2012, is comprised of the following components:

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation
	The consolidated financial statements are presented on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of the Company and its wholly- or majority-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Variable Interest Entities	Variable Interest Entities
	The Company accounts for arrangements that are not controlled through voting or similar rights as variable interest entities (“VIEs”). An enterprise is required to consolidate a VIE if it is the primary beneficiary of the VIE. A VIE is created when (i) the equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support from other parties, or (ii) the entity’s equity holders as a group either: (a) lack the power, through voting or similar rights, to direct the activities of the entity that most significantly impact the entity’s economic performance, (b) are not obligated to absorb expected losses of the entity if they occur, or (c) do not have the right to receive expected residual returns of the entity if they occur. If an entity is deemed to be a VIE, the enterprise that is deemed to have a variable interest, or combination of variable interests, that provides the enterprise with a controlling financial interest in the VIE, is considered the primary beneficiary and must consolidate the VIE.
	The Company has concluded that under certain circumstances when the Company (1) enters into option agreements for the purchase of land or facilities from an entity and pays anon-refundable deposit, or (2) enters into arrangements for the formation of joint ventures, a VIE may be created under condition (i), (ii) (b) or (c) of the previous paragraph. For each VIE created, the Company has performed a qualitative analysis, including considering which party, if any, has the power to direct the activities most significant to the economic performance of each VIE and whether that party has the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE. If the Company is determined to be the primary beneficiary of the VIE, the assets, liabilities and operations of the VIE are consolidated with the Company’s financial statements. Additionally, the Operating Partnership has notes payable to three trusts that are VIEs under condition (ii)(a) above. Since the Operating Partnership is not the primary beneficiary of the trusts, these VIEs are not consolidated.
	The Company’s investments in real estate joint ventures, where the Company has significant influence, but not control, and joint ventures which are VIEs in which the Company is not the primary beneficiary, are recorded under the equity method of accounting on the accompanying consolidated financial statements.
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.
Reclassifications	Reclassifications
	Certain amounts in the financial statements and supporting note disclosures have been reclassified to conform to the current year presentation. Such reclassifications did not impact previously reported net income or accumulated deficit.
Fair Value Disclosures	Fair Value Disclosures
	Derivative financial instruments
	Currently, the Company uses interest rate swaps to manage its interest rate risk. The valuation of these instruments 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 the derivatives, including the period to maturity, and uses observablemarket-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 incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. In conjunction with the Financial Accounting Standard Board’s fair value measurement guidance, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.
	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 its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of December 31, 2014, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.
	The table below presents the Company’s assets and liabilities measured at fair value on a recurring basis as of December 31, 2014, aggregated by the level in the fair value hierarchy within which those measurements fall.
		Fair Value Measurements at Reporting Date Using
	Description	December 31, 2014			Quoted Prices in Active			Significant Other			Significant
					Markets for Identical			Observable Inputs			Unobservable Inputs
					Assets (Level 1)			(Level 2)			(Level 3)
	Other assets—Cash Flow Hedge Swap Agreements	$	3,583		$	—		$	3,583		$	—
	Other liabilities—Cash Flow Hedge Swap Agreements	$	(3,533	)	$	—		$	(3,533	)	$	—
	There were no transfers of assets and liabilities between Level 1 and Level 2 during the year ended December 31, 2014. The Company did not have any significant assets or liabilities that are re-measured on a recurring basis using significant unobservable inputs as of December 31, 2014 or 2013.
	Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
	Long-lived assets held for use are evaluated by the Company for impairment when events or circumstances indicate that there may be impairment. The Company reviews each store at least annually to determine if any such events or circumstances have occurred or exist. The Company focuses on stores where occupancy and/or rental income have decreased by a significant amount. For these stores, the Company determines whether the decrease is temporary or permanent and whether the store will likely recover the lost occupancy and/or revenue in the short term. In addition, the Company reviews stores in the lease-up stage and compares actual operating results to original projections.
	When the Company determines that an event that may indicate impairment has occurred, the Company compares the carrying value of the related long-lived assets to the undiscounted future net operating cash flows attributable to the assets. An impairment loss is recorded if the net carrying value of the assets exceeds the undiscounted future net operating cash flows attributable to the assets. The impairment loss recognized equals the excess of net carrying value over the related fair value of the assets.
	When real estate assets are identified by management as held for sale, the Company discontinues depreciating the assets and estimates the fair value of the assets, net of selling costs. If the estimated fair value, net of selling costs, of the assets that have been identified for sale is less than the net carrying value of the assets, then a valuation allowance is established. The operations of assets held for sale or sold during the period are generally presented as discontinued operations for all periods presented.
	The Company assesses whether there are any indicators that the value of the Company’s investments in unconsolidated real estate ventures may be impaired annually and when events or circumstances indicate that there may be impairment. An investment is impaired if management’s estimate of the fair value of the investment is less than its carrying value. To the extent impairment has occurred, and is considered to be other than temporary, the loss is measured as the excess of the carrying amount of the investment over the fair value of the investment.
	As of December 31, 2014 and 2013, the Company did not have any assets or liabilities measured at fair value on a nonrecurring basis.
	Fair Value of Financial Instruments
	The carrying values of cash and cash equivalents, restricted cash, receivables, other financial instruments included in other assets, accounts payable and accrued expenses, variable-ratenotes payable, lines of credit and other liabilities reflected in the consolidated balance sheets at December 31, 2014 and 2013, approximate fair value.
	The fair values of the Company’s notes receivable from Preferred Operating Partnership unit holders was based on the discounted estimated future cash flow of the notes (categorized within Level 3 of the fair value hierarchy); the discount rate used approximated the current market rate for loans with similar maturities and credit quality. The fair values of the Company’s fixed rate notes payable and notes payable to trusts were estimated using the discounted estimated future cash payments to be made on such debt (categorized within Level 3 of the fair value hierarchy); the discount rates used approximated current market rates for loans, or groups of loans, with similar maturities and credit quality. The fair value of the Company’s exchangeable senior notes was estimated using an average market price for similar securities obtained from a third party.
	The fair values of the Company’s fixed-rate assets and liabilities were as follows for the periods indicated:
		December 31, 2014						December 31, 2013
		Fair			Carrying			Fair			Carrying
		Value			Value			Value			Value
	Notes receivable from Preferred Operating Partnership unit holders	$	126,380		$	120,230		$	103,491		$	100,000
	Fixed rate notes payable and notes payable to trusts	$	1,320,370		$	1,283,893		$	1,365,290		$	1,368,885
	Exchangeable senior notes	$	276,095		$	250,000		$	251,103		$	250,000
Real Estate Assets	Real Estate Assets
	Real estate assets are stated at cost, less accumulated depreciation. Direct and allowable internal costs associated with the development, construction, renovation, and improvement of real estate assets are capitalized. Interest, property taxes, and other costs associated with development incurred during the construction period are capitalized. The construction period begins when expenditures for the real estate assets have been made and activities that are necessary to prepare the asset for its intended use are in progress. The construction period ends when the asset is substantially complete and ready for its intended use.
	Expenditures for maintenance and repairs are charged to expense as incurred. Major replacements and betterments that improve or extend the life of the asset are capitalized and depreciated over their estimated useful lives. Depreciation is computed using the straight-line method over the estimated useful lives of the buildings and improvements, which are generally between five and 39 years.
	In connection with the Company’s acquisition of stores, the purchase price is allocated to the tangible and intangible assets and liabilities acquired based on their fair values, which are estimated using significant unobservable inputs. The value of the tangible assets, consisting of land and buildings, are determined as if vacant. Intangible assets, which represent the value of existing tenant relationships, are recorded at their fair values based on the avoided cost to replace the current leases. The Company measures the value of tenant relationships based on the rent lost due to the amount of time required to replace existing customers which is based on the Company’s historical experience with turnover in its facilities. Debt assumed as part of an acquisition is recorded at fair value based on current interest rates compared to contractual rates. Acquisition-related transaction costs are expensed as incurred.
	Intangible lease rights represent: (1) purchase price amounts allocated to leases on three stores that cannot be classified as ground or building leases; these rights are amortized to expense over the life of the leases and (2) intangibles related to ground leases on five stores where the leases were assumed by the Company at rates that were lower than the current market rates for similar leases. The values associated with these assumed leases were recorded as intangibles, which will be amortized over the lease terms.
Investments in Real Estate Ventures	Investments in Real Estate Ventures
	The Company’s investments in real estate joint ventures, where the Company has significant influence, but not control and joint ventures which are VIEs in which the Company is not the primary beneficiary, are recorded under the equity method of accounting in the accompanying consolidated financial statements.
	Under the equity method, the Company’s investment in real estate ventures is stated at cost and adjusted for the Company’s share of net earnings or losses and reduced by distributions. Equity in earnings of real estate ventures is generally recognized based on the Company’s ownership interest in the earnings of each of the unconsolidated real estate ventures. For the purposes of presentation in the statement of cash flows, the Company follows the “look through” approach for classification of distributions from joint ventures. Under this approach, distributions are reported under operating cash flow unless the facts and circumstances of a specific distribution clearly indicate that it is a return of capital (e.g., a liquidating dividend or distribution of the proceeds from the joint venture’s sale of assets), in which case it is reported as an investing activity.

	The Company’s cash is deposited with financial institutions located throughout the United States and at times may exceed federally insured limits. The Company considers all highly liquid debt instruments with a maturity date of three months or less to be cash equivalents.
Restricted Cash	Restricted Cash
	Restricted cash is comprised of letters of credit and escrowed funds deposited with financial institutions located throughout the United States relating to earnest money deposits on potential acquisitions, real estate taxes, insurance and capital expenditures.
Other Assets	Other Assets
	Other assets consist primarily of equipment and fixtures, deferred financing costs, customer accounts receivable, investments in trusts, notes receivable, other intangible assets, income taxes receivable, deferred tax assets, prepaid expenses and the fair value of interest rate swaps. Depreciation of equipment and fixtures is computed on a straight-line basis over three to five years. Deferred financing costs are amortized to interest expense using the effective interest method over the terms of the respective debt agreements.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities
	The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. 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.
	The Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.
Risk Management and Use of Financial Instruments	Risk Management and Use of Financial Instruments
	In the normal course of its ongoing business operations, the Company encounters economic risk. There are three main components of economic risk: interest rate risk, credit risk and market risk. The Company is subject to interest rate risk on its interest-bearing liabilities. Credit risk is the risk of inability or unwillingness of tenants to make contractually required payments. Market risk is the risk of declines in the value of stores due to changes in rental rates, interest rates or other market factors affecting the value of stores held by the Company. The Company has entered into interest rate swap agreements to manage a portion of its interest rate risk.
Exchange of Common Operating Partnership Units and Classification of Noncontrolling Interests	Exchange of Common Operating Partnership Units
	Redemption of common Operating Partnership units for shares of common stock, when redeemed under the original provisions of the Operating Partnership agreement, are accounted for by reclassifying the underlying net book value of the units from noncontrolling interest to the Company’s equity. The difference between the fair value of the consideration paid and the adjustment to the carrying amount of the noncontrolling interest is recognized as additional paid in capital for the Company.
Revenue and Expense Recognition	Revenue and Expense Recognition
	Rental revenues are recognized as earned based upon amounts that are currently due from tenants. Leases are generally on month-to-month terms. Prepaid rents are recognized on astraight-line basis over the term of the leases. Promotional discounts are recognized as a reduction to rental income over the promotional period. Late charges, administrative fees, merchandise sales and truck rentals are recognized as income when earned. Management fee revenues are recognized monthly as services are performed and in accordance with the terms of the related management agreements. Equity in earnings of unconsolidated real estate entities is recognized based on our ownership interest in the earnings of each of the unconsolidated real estate entities. Interest income is recognized as earned.
	Property expenses, including utilities, property taxes, repairs and maintenance and other costs to manage the facilities are recognized as incurred. The Company accrues for property tax expense based upon invoice amounts, estimates and historical trends. If these estimates are incorrect, the timing of expense recognition could be affected.
	Tenant reinsurance premiums are recognized as revenue over the period of insurance coverage. The Company records an unpaid claims liability at the end of each period based on existing unpaid claims and historical claims payment history. The unpaid claims liability represents an estimate of the ultimate cost to settle all unpaid claims as of each period end, including both reported but unpaid claims and claims that may have been incurred but have not been reported. The Company uses a third party claims administrator to adjust all tenant reinsurance claims received. The administrator evaluates each claim to determine the ultimate claim loss and includes an estimate for claims that may have been incurred but not reported. Annually, a third party actuary evaluates the adequacy of the unpaid claims liability. Prior year claim reserves are adjusted as experience develops or new information becomes known. The impact of such adjustments is included in the current period operations. The unpaid claims liability is not discounted to its present value. Each tenant chooses the amount of insurance coverage they want through the tenant reinsurance program. Tenants can purchase policies in amounts of two thousand dollars to ten thousand dollars of insurance coverage in exchange for a monthly fee. As of December 31, 2014, the average insurance coverage for tenants was approximately $2,540. The Company’s exposure per claim is limited by the maximum amount of coverage chosen by each tenant. The Company purchases reinsurance for losses exceeding a set amount for any one event. The Company does not currently have any amounts recoverable under the reinsurance arrangements.
Real Estate Sales	Real Estate Sales
	In general, sales of real estate and related profits/losses are recognized when all consideration has changed hands and risks and rewards of ownership have been transferred. Certain types of continuing involvement preclude sale treatment and related profit recognition; other forms of continuing involvement allow for sale recognition but require deferral of profit recognition.
Advertising Costs	Advertising Costs
	The Company incurs advertising costs primarily attributable to internet, directory and other advertising. These costs are expensed as incurred. The Company recognized $8,370, $6,482, and $6,026 in advertising expense for the years ended December 31, 2014, 2013 and 2012, respectively.
Income Taxes	Income Taxes
	The Company has elected to be treated as a REIT under Sections 856 through 860 of the Internal Revenue Code. In order to maintain its qualification as a REIT, among other things, the Company is required to distribute at least 90% of its REIT taxable income to its stockholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to federal income tax with respect to that portion of its income which meets certain criteria and is distributed annually to stockholders. The Company plans to continue to operate so that it meets the requirements for taxation as a REIT. Many of these requirements, however, are highly technical and complex. If the Company were to fail to meet these requirements, it would be subject to federal income tax. The Company is subject to certain state and local taxes. Provision for such taxes has been included in income tax expense on the Company’s consolidated statements of operations. For the year ended December 31, 2014, 0.0% (unaudited) of all distributions to stockholders qualified as a return of capital.
	The Company has elected to treat its corporate subsidiary, Extra Space Management, Inc. (“ESMI”), as a taxable REIT subsidiary (“TRS”). In general, the Company’s TRS may perform additional services for tenants and may engage in any real estate or non-real estate related business. A TRS is subject to corporate federal income tax. ESM Reinsurance Limited, a wholly-ownedsubsidiary of ESMI, generates income from insurance premiums that are subject to corporate federal income tax and state insurance premiums tax.
	Deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities. At December 31, 2014 and 2013, there were no material unrecognized tax benefits. Interest and penalties relating to uncertain tax positions will be recognized in income tax expense when incurred. As of December 31, 2014 and 2013, the Company had no interest or penalties related to uncertain tax provisions.
Stock-Based Compensation	Stock-Based Compensation
	The measurement and recognition of compensation expense for all share-based payment awards to employees and directors are based on estimated fair values. Awards granted are valued at fair value and any compensation element is recognized on a straight line basis over the service periods of each award.
Earnings Per Common Share	Earnings Per Common Share
	Basic earnings per common share is computed using the two-class method by dividing net income attributable to common stockholders by the weighted average number of common shares outstanding during the period. All outstanding unvested restricted stock awards contain rights to non-forfeitable dividends and participate in undistributed earnings with common stockholders; accordingly, they are considered participating securities that are included in the two-class method. Diluted earnings per common share measures the performance of the Company over the reporting period while giving effect to all potential common shares that were dilutive and outstanding during the period. The denominator includes the weighted average number of basic shares and the number of additional common shares that would have been outstanding if the potential common shares that were dilutive had been issued, and is calculated using either the two-class, treasury stock or as if-converted method, whichever is most dilutive. Potential common shares are securities (such as options, convertible debt, Series A Participating Redeemable Preferred Units (“Series A Units”), Series B Redeemable Preferred Units (“Series B Units”), Series C Convertible Redeemable Preferred Units (“Series C Units”), Series D Redeemable Preferred Units (“Series D Units”) and common Operating Partnership units (“OP Units”)) that do not have a current right to participate in earnings of the Company but could do so in the future by virtue of their option, redemption or conversion right.
	In computing the dilutive effect of convertible securities, net income is adjusted to add back any changes in earnings in the period associated with the convertible security. The numerator also is adjusted for the effects of any other non-discretionary changes in income or loss that would result from the assumed conversion of those potential common shares. In computing diluted earnings per common share, only potential common shares that are dilutive (those that reduce earnings per common share) are included. For the years ended December 31, 2014, 2013 and 2012, options to purchase approximately 27,374 shares, 44,958 shares and 57,335 shares of common stock, respectively, were excluded from the computation of earnings per share as their effect would have been anti-dilutive. As of December 31, 2014, 764,385 Series B Units, 489,366 Series C Units and 6,492 Series D Units were excluded from the computation of earnings per share as their effect would have been anti-dilutive. As of December 31, 2013, 3,334,956 OP Units, 257,266 Series B Units and 33,302 Series C Units were excluded from the computation of earnings per share as their effect would have been anti-dilutive. As of December 31, 2012, 2,755,650 OP Units were excluded from the computation of earnings per share as their effect would have beenanti-dilutive.
	The Company’s Operating Partnership had $250,000 of its 2.375% Exchangeable Senior Notes due 2033 (the “Notes due 2033”) issued and outstanding as of December 31, 2014. The Notes due 2033 could potentially have a dilutive impact on the Company’s earnings per share calculations. The Notes due 2033 are exchangeable by holders into shares of the Company’s common stock under certain circumstances per the terms of the indenture governing the Notes due 2033. The exchange price of the Notes due 2033 was $55.62 per share as of December 31, 2014, and could change over time as described in the indenture. The Company has irrevocably agreed to pay only cash for the accreted principal amount of the Notes due 2033 relative to its exchange obligations, but retained the right to satisfy the exchange obligation in excess of the accreted principal amount in cash and/or common stock. Though the Company has retained that right, Accounting Standards Codification (“ASC”) 260, “Earnings per Share,” requires an assumption that shares would be used to pay the exchange obligation in excess of the accreted principal amount, and requires that those shares be included in the Company’s calculation of weighted average common shares outstanding for the diluted earnings per share computation. For the year ended December 31, 2014, 130,883 shares related to the Notes due 2033 were included in the computation for diluted earnings per share. For the year ended December 31, 2013, no shares related to the Notes due 2033 were included in the computation for diluted earnings per share as the exchange price exceeded the per share price of the Company’s common stock during this period.
	For the purposes of computing the diluted impact on earnings per share of the potential exchange of Series A Units for common shares upon redemption, where the Company has the option to redeem in cash or shares and where the Company has stated the positive intent and ability to settle at least $115,000 of the instrument in cash (or net settle a portion of the Series A Units against the related outstanding note receivable), only the amount of the instrument in excess of $115,000 is considered in the calculation of shares contingently issuable for the purposes of computing diluted earnings per share as allowed by ASC 260-10-45-46.
	For the purposes of computing the diluted impact on earnings per share of the potential exchange of Series B Units for common shares upon redemption, where the Company has the option to redeem in cash or shares and where the Company has stated the intent and ability to settle the redemption in shares, the Company divided the total value of the Series B Units outstanding as of December 31, 2014 of $41,902 by the closing price of the Company’s common stock as of December 31, 2014 of $58.64 per share. Assuming full exchange for common shares as of December 31, 2014, 714,566 shares would have been issued to the holders of the Series B Units.
	For the purposes of computing the diluted impact on earnings per share of the potential exchange of Series C Units into common shares upon redemption, where the Company has the option to redeem in cash or shares and where the Company has stated the intent and ability to settle the redemption in shares, the Company divided the total value of the Series C Units outstanding as of December 31, 2014 of $29,639 by the closing price of the Company’s common stock as of December 31, 2014 of $58.64 per share. Assuming full exchange for common shares as of December 31, 2014, 505,441 shares would have been issued to the holders of the Series C Units.
	For the purposes of computing the diluted impact on earnings per share of the potential exchange of Series D Units into common shares upon redemption, where the Company has the option to redeem in cash or shares and where the Company has stated the intent and ability to settle the redemption in shares, the Company divided the total value of the Series D Units outstanding as of December 31, 2014 of $13,710 by the closing price of the Company’s common stock as of December 31, 2014 of $58.64 per share. Assuming full exchange for common shares as of December 31, 2014, 233,795 shares would have been issued to the holders of Series D Units.

Recently Issued Accounting Standards	Recently Issued Accounting Standards
	In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-09, “Revenues from Contracts with Customers” (“ASU 2014-09”). ASU 2014-09 amends the guidance for revenue recognition to replace numerous, industry-specific requirements and converges areas under this topic with those of the International Financial Reporting Standards. ASU 2014-09 outlines a five-step process for customer contract revenue recognition that focuses on transfer of control, as opposed to transfer of risk and rewards. The amendment also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenues and cash flows from contracts with customers. ASU 2014-09 is effective for reporting periods beginning after December 15, 2016, and early adoption is prohibited. Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. Management is currently assessing the impact of the adoption of ASU 2014-09 on the Company’s consolidated financial statements.
Convertible Debt	GAAP requires entities with convertible debt instruments that may be settled entirely or partially in cash upon conversion to separately account for the liability and equity components of the instrument in a manner that reflects the issuer’s economic interest cost. The Company therefore accounts for the liability and equity components of the Notes due 2033 separately. The equity component is included in paid-in capital in stockholders’ equity in the consolidated balance sheet, and the value of the equity component is treated as original issue discount for purposes of accounting for the debt component. The discount is being amortized as interest expense over the remaining period of the debt through its first redemption date, July 1, 2018. The effective interest rate on the liability component is 4.0%.
