Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization
	1	Organization
	Rexford Industrial Realty, Inc. is a self-administered and self-managed full-service real estate investment trust (“REIT”) focused on owning and operating industrial properties in Southern California infill markets. We were formed as a Maryland corporation on January 18, 2013 and Rexford Industrial Realty, L.P. (the “Operating Partnership”), of which we are the sole general partner, was formed as a Maryland limited partnership on January 18, 2013. Through our controlling interest in our Operating Partnership and its subsidiaries, we own, manage, lease, acquire and develop industrial real estate primarily located in Southern California infill markets.  As of March 31, 2015, our consolidated portfolio consisted of 102 properties with approximately 10.3 million rentable square feet.  We also own a 15% interest in a joint venture that owns one property with approximately 0.5 million square feet, which we also manage.   In addition, we currently manage an additional 19 properties with approximately 1.2 million rentable square feet.
	The terms “us,” “we,” “our,” and the “Company” as used in these financial statements refer to Rexford Industrial Realty, Inc. and its subsidiaries (including our Operating Partnership).
	Basis of Presentation
	As of March 31, 2015 and December 31, 2014 and for the three months ended March 31, 2015 and 2014, the financial statements presented are the consolidated financial statements of Rexford Industrial Realty, Inc. and its subsidiaries, including our Operating Partnership. All significant intercompany balances and transactions have been eliminated in the consolidated financial statements.
	The accompanying unaudited interim financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in the financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) may have been condensed or omitted pursuant to SEC rules and regulations, although we believe that the disclosures are adequate to make their presentation not misleading. The accompanying unaudited financial statements include, in our opinion, all adjustments, consisting of normal recurring adjustments, necessary to present fairly the financial information set forth therein. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. The interim financial statements should be read in conjunction with the combined and consolidated financial statements in our 2014 Annual Report on Form 10-K and the notes thereto. Certain prior period amounts have been reclassified to conform to current period presentation. Any references to the number of properties and square footage are unaudited and outside the scope of our independent registered public accounting firm’s review of our financial statements in accordance with the standards of the United States Public Company Accounting Oversight Board.
	The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
	We consolidate all entities that are wholly owned and those in which we own less than 100% but control, as well as any variable interest entities in which we are the primary beneficiary. We evaluate our ability to control an entity and whether the entity is a variable interest entity and we are the primary beneficiary through consideration of the substantive terms of the arrangement to identify which enterprise has the power to direct the activities of a variable interest entity that most significantly impacts the entity’s economic performance and the obligation to absorb losses of the entity or the right to receive benefits from the entity. Investments in entities in which we do not control but over which we have the ability to exercise significant influence over operating and financial policies are presented under the equity method. Investments in entities that we do not control and over which we do not exercise significant influence are carried at the lower of cost or fair value, as appropriate. Our ability to correctly assess our influence and/or control over an entity affects the presentation of these investments in our consolidated financial statements.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2	Summary of Significant Accounting Policies
	Cash and Cash Equivalents
	Cash and cash equivalents include all cash and liquid investments with an initial maturity of three months or less. The carrying amount approximates fair value due to the short term maturity of these investments.
	Discontinued Operations
	On April 14, 2014, the FASB issued Accounting Standards Update 2014-08: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (“ASU 2014-08”).  Under ASU 2014-08, only disposals that represent a strategic shift that has (or will have) a major effect on the entity’s results and operations would qualify as discontinued operations. ASU 2014-08 further expands the disclosure requirements for disposals that meet the definition of a discontinued operation, and requires entities to disclose information about disposals of individually significant components.  We elected to adopt ASU 2014-08 early, beginning in the fiscal quarter ended September 30, 2014.  The adoption of ASU 2014-08 has and will likely result in fewer property sales being classified as discontinued operations.
	During the three months ended March 31, 2014, we sold two of our operating properties.  As these properties were sold and classified as held for sale prior to the adoption of ASU 2014-08, the revenues and expenses of these properties are reported as discontinued operations in the consolidated statements of operations for all periods presented through the date of the disposition.  Furthermore, the gain (loss) on sale of these properties is reported as discontinued operations in the consolidated statements of operations in the period the properties are sold. See Note 13.
	Investment in Real Estate
	Acquisitions
	When we acquire operating properties, with the intention to hold the investment for the long-term, we allocate the purchase price to the various components of the acquisition based upon the fair value of each component. The components typically include land, building and improvements, intangible assets related to above and below market leases, intangible assets related to in-place leases, debt and other assumed assets and liabilities.  The initial allocation of the purchase price is based on management’s preliminary assessment, which may differ when final information becomes available. Subsequent adjustments made to the initial purchase price allocation are made within the allocation period, which typically does not exceed one year.
	We allocate the purchase price to the fair value of the tangible assets by valuing the property as if it were vacant. We consider Level 3 inputs, which are unobservable inputs based on the Company’s assumptions about the assumptions a market participant would use, such as the replacement cost of such assets, appraisals, property condition reports, comparable market rental data and other related information.
	In determining the fair value of intangible lease assets or liabilities, we also consider Level 3 inputs. Acquired above and below market leases are valued based on the present value of the difference between prevailing market rates and the in-place rates measured over a period equal to the remaining term of the lease for above market leases and the initial term plus the term of any below market fixed rate renewal options for below market leases, if applicable.  The estimated fair value of acquired in-place at-market tenant leases are the costs that would have been incurred to lease the property to the occupancy level of the property at the date of acquisition. Such estimates include the value associated with leasing commissions, legal and other costs, as well as the estimated period necessary to lease such property that would be incurred to lease the property to its occupancy level at the time of its acquisition. Acquisition costs associated with the business combination are expensed in the period they are incurred.
	The difference between the fair value and the face value of debt assumed in connection with an acquisition is recorded as a premium or discount and amortized to “interest expense” over the life of the debt assumed. The valuation of assumed liabilities is based on our estimate of the current market rates for similar liabilities in effect at the acquisition date.
	For acquisitions that do not meet the accounting criteria to be accounted for as a business combination, we record to land and building the purchase price paid and capitalize the associated acquisition costs.  We capitalized $36,000 and $42,000 in acquisition costs during the three months ended March 31, 2015 and 2014, respectively.  See Note 3.
	Capitalization of Costs
	We capitalize costs incurred in developing, renovating, rehabilitating, and improving real estate assets as part of the investment basis. Costs incurred in making repairs and maintaining real estate assets are expensed as incurred. During the land development and construction periods, we capitalize interest, insurance, real estate taxes and certain general and administrative costs, including direct payroll, bonus and noncash equity compensation, of the personnel performing development, renovations, and rehabilitation if such costs are incremental and identifiable to a specific activity to get the asset ready for its intended use. Capitalized costs are included in the investment basis of real estate assets.
	Depreciation and Amortization
	Real estate, including land, building and land improvements, tenant improvements, and furniture, fixtures and equipment, leasing costs and intangible lease assets and liabilities are stated at historical cost less accumulated depreciation and amortization, unless circumstances indicate that the cost cannot be recovered, in which case, the carrying value of the property is reduced to estimated fair value as discussed below in our policy with regards to impairment of long-lived assets. We estimate the depreciable portion of our real estate assets and related useful lives in order to record depreciation expense. Our ability to estimate the depreciable portions of our real estate assets and useful lives is critical to the determination of the appropriate amount of depreciation and amortization expense recorded and the carrying value of the underlying assets. Any change to the assets to be depreciated and the estimated depreciable lives of these assets would have an impact on the depreciation expense recognized.
	The values allocated to buildings, site improvements, in-place leases, tenant improvements and leasing costs are depreciated on a straight-line basis using an estimated remaining life of 10-30 years for buildings, 20 years for site improvements, and the shorter of the estimated useful life or respective lease term for tenant improvements.
	As discussed above in investments in real estate, in connection with property acquisitions, we may acquire leases with rental rates above or below the market rental rates. Such differences are recorded as an intangible lease asset or liability and amortized to “rental revenues” over the reasonably assured term of the related leases. The unamortized balances of these assets and liabilities associated with the early termination of leases are fully amortized to their respective revenue line items in our consolidated financial statements over the shorter of the expected life of such assets and liabilities or the remaining lease term.
	Our estimate of the useful life of our assets is evaluated upon acquisition and when circumstances indicate a change in the useful life, which requires significant judgment regarding the economic obsolescence of tangible and intangible assets.
	Impairment of Long-Lived Assets
	In accordance with the provisions of the Impairment or Disposal of Long-Lived Assets Subsections of ASC Topic 360: Property, Plant, and Equipment, we assess the carrying values of our respective long-lived assets, including goodwill, whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable.
	Recoverability of real estate assets is measured by comparison of the carrying amount of the asset to the estimated future undiscounted cash flows. In order to review real estate assets for recoverability, we consider current market conditions as well as our intent with respect to holding or disposing of the asset. The intent with regards to the underlying assets might change as market conditions and other factors change. Fair value is determined through various valuation techniques; including discounted cash flow models, applying a capitalization rate to estimated net operating income of a property, quoted market values and third party appraisals, where considered necessary. The use of projected future cash flows is based on assumptions that are consistent with estimates of future expectations and the strategic plan used to manage our underlying business. If our analysis indicates that the carrying value of the real estate asset is not recoverable on an undiscounted cash flow basis, we will recognize an impairment charge for the amount by which the carrying value exceeds the current estimated fair value of the real estate property.
	Assumptions and estimates used in the recoverability analyses for future cash flows, discount rates and capitalization rates are complex and subjective. Changes in economic and operating conditions or our intent with respect to our investment that occur subsequent to our impairment analyses could impact these assumptions and result in future impairment of our real estate properties.
	Investment in Unconsolidated Real Estate
	Investments in unconsolidated real estate in which we have the ability to exercise significant influence (but not control) are accounted for under the equity method of investment.  Under the equity method, we initially record our investment at cost, and subsequently adjust for equity in earnings or losses and cash contributions and distributions. Any difference between the carrying amount of these investments on the balance sheet and the underlying equity in net assets is amortized as an adjustment to equity in income (loss) from unconsolidated real estate over the life of the related asset. Under the equity method of accounting, our net equity investment is reflected within the consolidated balance sheets, and our share of net income or loss from the joint ventures is included within the consolidated statements of operations.  See Note 12.
	Income Taxes
	We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”) commencing with our initial taxable year ended December 31, 2013. To qualify as a REIT, we are required (among other things) to distribute at least 90% of our REIT taxable income to our stockholders and meet the various other requirements imposed by the Code relating to matters such as operating results, asset holdings, distribution levels and diversity of stock ownership. Provided we qualify for taxation as a REIT, we are generally not subject to corporate-level income tax on the earnings distributed currently to our stockholders that we derive from our REIT qualifying activities. If we fail to qualify as a REIT in any taxable year, and were unable to avail ourselves of certain savings provisions set forth in the Code, all of our taxable income would be subject to federal income tax at regular corporate rates, including any applicable alternative minimum tax.
	In addition, we are subject to taxation by various state and local jurisdictions, including those in which we transact business or reside. Our non-taxable REIT subsidiaries, including our Operating Partnership, are either partnerships or disregarded entities for federal income tax purposes. Under applicable federal and state income tax rules, the allocated share of net income or loss from disregarded entities (including limited partnerships and S-Corporations) is reportable in the income tax returns of the respective partners and stockholders. Accordingly, no income tax provision is included in the accompanying consolidated financial statements for the three months ended March 31, 2015 and 2014.
	We periodically evaluate our tax positions to determine whether it is more likely than not that such positions would be sustained upon examination by a tax authority for all open tax years, as defined by the statute of limitations, based on their technical merits. As of March 31, 2015 and December 31, 2014, we have not established a liability for uncertain tax positions.
	Derivative Instruments and Hedging Activities
	FASB ASC Topic 815: Derivatives and Hedging (“ASC 815”), provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments.
	As required by ASC 815, we record 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, and whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. 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.  We may enter into derivative contracts that are intended to economically hedge certain risks, even though hedge accounting does not apply or we elect not to apply hedge accounting.  See Note 8.
	Revenue Recognition
	We recognize revenue from rent, tenant reimbursements and other revenue sources once all of the following criteria are met: persuasive evidence of an arrangement exists, the delivery has occurred or services rendered, the fee is fixed and determinable and collectability is reasonably assured. Minimum annual rental revenues are recognized in rental revenues on a straight-line basis over the term of the related lease. Rental revenue recognition commences when the tenant takes possession or controls the physical use of the leased space.
	Estimated reimbursements from tenants for real estate taxes, common area maintenance and other recoverable operating expenses are recognized as revenues in the period that the expenses are incurred. Subsequent to year-end, we perform final reconciliations on a lease-by-lease basis and bill or credit each tenant for any cumulative annual adjustments. Lease termination fees, which are included in rental revenues in the accompanying consolidated statements of operations, are recognized when the related lease is canceled and we have no continuing obligation to provide services to such former tenant.
	Revenues from management, leasing and development services are recognized when the related services have been provided and earned.
	The recognition of gains on sales of real estate requires us to measure the timing of a sale against various criteria related to the terms of the transaction, as well as any continuing involvement in the form of management or financial assistance associated with the property. If the sales criteria are not met, we defer gain recognition and account for the continued operations of the property by applying the finance, profit-sharing or leasing method. If the sales criteria have been met, we further analyze whether profit recognition is appropriate using the full accrual method. If the criteria to recognize profit using the full accrual method have not been met, we defer the gain and recognize it when the criteria are met or use the installment or cost recovery method as appropriate under the circumstances. See Note 13 for discussion of dispositions.
	Valuation of Receivables
	We are subject to tenant defaults and bankruptcies that could affect the collection of outstanding receivables. In order to mitigate these risks, we perform credit reviews and analyses on prospective tenants before significant leases are executed and on existing tenants before properties are acquired. We specifically analyze aged receivables, customer credit-worthiness, historical bad debts and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. As a result of our periodic analysis, we maintain an allowance for estimated losses that may result from the inability of our tenants to make required payments. This estimate requires significant judgment related to the lessees’ ability to fulfill their obligations under the leases. We believe our allowance for doubtful accounts is adequate for our outstanding receivables for the periods presented. If a tenant is insolvent or files for bankruptcy protection and fails to make contractual payments beyond any allowance, we may recognize additional bad debt expense in future periods equal to the net outstanding balances, which include amounts recognized as straight-line revenue not realizable until future periods. We recorded a provision for doubtful accounts of approximately $0.4 million and $0.4 million for the three months ended March 31, 2015 and 2014, respectively, as a reduction to rental revenues in our consolidated statements of operations. We had a $1.3 million and $1.0 million reserve for allowance for doubtful accounts as of March 31, 2015 and December 31, 2014, respectively.
	Equity Based Compensation
	We account for equity-based compensation, including shares of restricted stock, in accordance with ASC Topic 718 Compensation – Stock Compensation.  For share-based awards that vest based solely on a service condition, we recognize compensation cost on a straight-line basis over the total requisite service period for the entire award.  The total compensation expense for these awards is based upon the fair market value of the shares on the grant date, adjusted for estimated forfeitures.  See Note 14.
	Equity Offering Costs
	Underwriting commissions and offering costs have been reflected as a reduction of additional paid-in capital.
	Earnings Per Share
	We calculate earnings per share (“EPS”) in accordance with ASC 260 – Earnings Per Share (“ASC 260”).  Under ASC 260, shares of unrestricted stock that contain non-forfeitable rights to dividends are participating securities and, therefore, are included in computing basic EPS pursuant to the two-class method. The two-class method determines EPS for each class of common stock and participating securities according to dividends declared (or accumulated) and their respective participation rights in undistributed earnings.
	Basic EPS is calculated by dividing the net income (loss) attributable to common stockholders by the weighted average shares of common stock outstanding for the period. Diluted EPS is computed using the weighted average shares of common stock outstanding determined for the basic EPS computation plus the effect of any dilutive securities, including the dilutive effect of unvested restricted common stock using the treasury stock method. See Note 15.
	Segment Reporting
	Management views the Company as a single reportable segment based on its method of internal reporting in addition to its allocation of capital and resources.
	Recently Issued Accounting Pronouncements
	Changes to GAAP are established by the FASB in the form of ASUs to the FASB’s Accounting Standards Codification. We consider the applicability and impact of all ASUs.
	On April 7, 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (“ASU 2015-03”).  ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a reduction from the carrying value of the debt liability. This offset against the debt liability is treated similarly to a debt discount, which effectively reduces the proceeds of a borrowing. ASU 2015-03 is effective for annual and interim periods beginning on or after December 15, 2015, with early adoption permitted on a retrospective basis.  We have elected to adopt ASU 2015-03 early, beginning with the current quarter ended March 31, 2015.  As a result of the adoption of ASU 2015-03, we have reclassified approximately $0.7 million of net debt issuance costs from an asset (previously recorded in the line item “Deferred loan costs, net” in the consolidated balance sheets) to a reduction in the carrying amount of our notes payable as of December 31, 2014.  ASU 2015-03 also expands disclosure requirements to include the face amount of the debt liability and the effective interest rate in the notes to the consolidated financial statements.  See Note 6.
	In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis ("ASU 2015-02"). ASU 2015-02 requires reporting entities to evaluate whether they should consolidate certain legal entities.  ASU 2015-02 modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (“VIEs”) or voting interest entities and eliminates the presumption that a general partner should consolidate a limited partnership. This ASU affects the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships. ASU 2015-02 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. A reporting entity may apply the amendments in the ASU using: (i) a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption; or (ii) by applying the amendments retrospectively. We are currently assessing the potential impact that the adoption of the ASU 2015-02 will have on our consolidated financial statements.
	On May 28, 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”).  ASU 2014-09 establishes principles for reporting the nature, amount, timing and uncertainty of revenues and cash flows arising from an entity's contracts with customers. The core principle of the new standard is that an entity recognizes revenue to represent the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This standard is effective for us in the first quarter of 2017 and will replace most existing revenue recognition guidance within GAAP. Early adoption is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We are currently evaluating ASU 2014-09 to determine its impact on our consolidated financial statements and related disclosures, as well as the transition method to apply the new standard.

	On January 21, 2015, in connection with the acquisition of the property located at 12907 Imperial Highway, we assumed a mortgage loan that is secured by the property.  The assumed mortgage loan had a principal balance of $5.4 million at the acquisition date and was recorded at fair value at the date of acquisition resulting in an initial debt premium of $473,000.  The loan, which was put in place in 2008 by the seller, bears interest at a fixed rate of 5.95% with amortization over 30 years, and has a maturity date of April 1, 2018.
	The following table summarizes the contractual debt maturities and scheduled amortization payments, excluding debt discounts/premiums and deferred loan costs, as of March 31, 2015 and does not consider extension options available to us as noted above:

	Thereafter			2,459,000
	Total		$	269,879,000
	Unsecured Credit Facility
	We have a senior unsecured revolving credit facility with borrowing capacity of $200.0 million (the “Revolver”) and a senior unsecured term loan facility (the “Term Loan Facility”) with borrowing capacity of $100.0 million (together the “Credit Facility”).  The Revolver is scheduled to mature on June 11, 2018 with one 12-month extension option available, subject to certain conditions, and the Term Loan Facility is scheduled to mature on June 11, 2019.  The aggregate principal amount of the Credit Facility may be increased to a total of up to $600.0 million, which may be comprised of additional revolving commitments under the Revolver or an increase to the Term Loan Facility, or any combination of the foregoing, subject to the satisfaction of specified conditions and the identification of lenders willing to make available such additional amounts.
	Interest on the Credit Facility is generally to be paid based upon, at our option, either (i) LIBOR plus the applicable LIBOR margin or (ii) the applicable base rate which is the greater of (a) the federal funds rate plus 0.50%, (b) the administrative agent’s prime rate or (c) the thirty-day LIBOR plus 1.00%, plus the applicable base rate margin. Until we attain an investment grade rating by two or more of Standard & Poor’s, Moody’s Investor Services and Fitch Ratings, the applicable LIBOR margin will range from1.30% to 1.90% for the Revolver and 1.25% to 1.85% for the Term Loan Facility, depending on the our Leverage Ratio (as defined in the credit agreement). In February 2015, the Revolver and the Term Loan Facility were assigned an investment grade rating of BBB- by Fitch Ratings. Additionally, there is a quarterly facility fee that is paid on the undrawn portion of the Revolver in an amount equal to 0.20% or 0.30% depending on the undrawn amount of the Revolver.
	The Credit Facility is guaranteed by the Company and by substantially all of the current and future subsidiaries of the Operating Partnership that own an unencumbered property. The Credit Facility is not secured by the Company’s properties or by equity interests in the subsidiaries that hold such properties.
	The Revolver and the Term Loan Facility may be voluntarily prepaid in whole or in part at any time without premium or penalty.  Amounts borrowed under the Term Loan Facility and repaid or prepaid may not be re-borrowed.
	The Credit Facility contains usual and customary events of default including defaults in the payment of principal, interest or fees, defaults in compliance with the covenants set forth in the Credit Facility and other loan documentation, cross-defaults to certain other indebtedness, and bankruptcy and other insolvency defaults. If an event of default occurs and is continuing under the Credit Facility, the unpaid principal amount of all outstanding loans, together with all accrued unpaid interest and other amounts owing in respect thereof, may be declared immediately due and payable.  We believe we are currently in compliance with all of the financial covenants required by our loan agreements.
	On March 31, 2015, we did not have any outstanding borrowings under our Revolver, leaving $200.0 million available for additional borrowings.
	Debt Covenants
	The Credit Facility includes a series of financial and other covenants that we must comply with in order to borrow under the Credit Facility.  These include the following covenants which are tested on a quarterly basis:
	·	Maintaining a ratio of total indebtedness to total asset value of not more than 60%;
	·	Maintaining a ratio of secured debt to total asset value of not more than 45%;
	·	Maintaining a ratio of total recourse debt to total asset value of not more than 15%;
	·	Maintaining a minimum tangible net worth of at least the sum of (i) $283,622,250, and (ii) an amount equal to at least 75% of the net equity proceeds received by the Company after March 31, 2014;
	·	Maintaining a ratio of adjusted EBITDA to fixed charges of at least 1.50 to 1.0;
	·	Maintaining a ratio of total unsecured debt to total unencumbered asset value of not more than 60%; and
	·	Maintaining a ratio of unencumbered NOI to unsecured interest expense of at least 1.75 to 1.0.
	Additionally, the Credit Facility provides that our distributions may not exceed the greater of (i) 95.0% of our funds from operations or (ii) the amount required for us to qualify and maintain our status as a REIT and avoid the payment of federal or state income or excise tax in any 12 month period.
	In addition to our Credit Facility, certain of our other loan agreements contain financial covenants to be tested quarterly.  The Glendale Commerce Center loan and our $60.0 million term loan both require a minimum Debt Service Coverage Ratio (as defined in their respective loan agreements) of at least 1.10 to 1.00.
	We believe we are in compliance with all of the financial covenants required by our loan agreements as of March 31, 2015.

	We are exposed to certain risk arising from both our business operations and economic conditions.  We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of our debt funding and the use of derivative financial instruments.  Specifically, we enter into derivative financial instruments to manage exposures that arise from business activities that result in the payment of future known and uncertain cash amounts, the value of which are determined by interest rates.  Our derivative financial instruments are used to manage differences in the amount, timing, and duration of our known or expected cash payments principally related to our borrowings.
	Derivative Instruments
	Our objectives in using interest rate derivatives are to add stability to interest expense and to manage exposure to interest rate movements. To accomplish this objective, we primarily use interest rate swaps as part of our interest rate risk management strategy.  Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for us making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. We do not use derivatives for trading or speculative purposes.
	The effective portion of the change in fair value of derivatives designated and qualifying as cash flow hedges is initially recorded in accumulated other comprehensive income (“AOCI”) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings.  The ineffective portion of the change in fair value of the derivatives is immediately recognized in earnings.
	On February 4, 2014, we executed two forward-starting interest rate swap transactions to hedge the variable cash flows associated with our existing $60.0 million variable-rate term loan.  Each of the two swaps has a notional value of $30.0 million. We are required to make certain monthly fixed rate payments calculated on notional amounts of $30.0 million for each of the swaps, while the applicable counterparty is obligated to make certain monthly floating rate payments based on LIBOR to us referencing the same notional amount.  The first forward swap will effectively fix the annual interest rate payable on $30.0 million of debt at 3.726% for the period from January 15, 2015 to February 15, 2019. The second forward swap will effectively fix the annual interest rate payable on the other $30.0 million of debt at 3.91% for the period from July 15, 2015 to February 15, 2019.
	On August 19, 2014, we executed two forward-starting interest rate swap transactions to hedge the variable cash flows associated with our $100.0 million Term Loan Facility.  Each of the two swaps has a notional value of $50.0 million.  The first swap has an effective date of August 14, 2015 and a maturity date of December 14, 2018.  The second swap has an effective date of February 16, 2016 and a maturity date of December 14, 2018.  We are required to make certain monthly fixed rate payments calculated on notional amounts of $50.0 million for each of the swaps, while the applicable counterparty is obligated to make certain monthly floating rate payments based on LIBOR to us referencing the same notional amount.  The interest rate swaps will effectively fix the annual interest rate payable on our Term Loan Facility at 1.79% for the first swap and 2.005% for the second swap, plus an applicable margin under the terms of the Credit Facility.
	The following table sets forth a summary of our interest rate swaps at March 31, 2015 and December 31, 2014:

	-1	We record all derivative instruments on a gross basis in the consolidated balance sheets, and accordingly, there are no offsetting amounts that net assets against liabilities.  As of March 31, 2015 and December 31, 2014, all of our derivatives were in a liability position, and as such, the fair value is included in the line item “Interest rate swap liability” in the consolidated balance sheets.
	The following table sets forth the impact of our interest rate swaps on our consolidated statements of operations for the periods presented:
			Three Months Ended March 31,
			2015			2014
	Interest Rate Swaps in Cash Flow Hedging Relationships:
	Amount of gain (loss) recognized in AOCI on derivatives (effective portion)		$	(1,982,000	)	$	300,000
	Amount of gain (loss) reclassified from AOCI into earnings under "Interest expense" (effective portion)			(105,000	)		-
	Amount of gain (loss) recognized in earnings under "Interest expense" (ineffective portion and amount excluded from effectiveness testing)			-			-
	During the next twelve months, we estimate that an additional $1,307,000 will be reclassified from AOCI as an increase to interest expense.
	Credit-risk-related Contingent Features
	Certain of our agreements with our derivative counterparties that contain a provision where if we default on any of our indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender within a specified time period, then we could also be declared in default on its derivative obligations.
	Certain of our agreements with our derivative counterparties contain provisions where if a merger or acquisition occurs that materially changes our creditworthiness in an adverse manner, we may be required to fully collateralize our obligations under the derivative instrument.
	As of March 31, 2015, the fair value of interest rate swaps in a net liability position, which excludes any adjustment for nonperformance risk related to these agreements, was $3,368,000.  As of March 31, 2015, we have not posted any collateral related to these agreements.

Fair Value Disclosures [Abstract]
Fair Value Measurements	9	Fair Value Measurements
	We have adopted FASB Accounting Standards Codification Topic 820: Fair Value Measurements and Disclosure (ASC 820). ASC 820 defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements.  ASC 820 applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the standard does not require any new fair value measurements of reported balances.
	ASC 820 emphasizes that fair value is a market-based measurement, not an entity-specific measurement.  Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability.  As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).
	Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.
	Recurring Measurements – Interest Rate Swaps
	Currently, we use interest rate swap agreements to manage our 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 observable market-based inputs, including interest rate curves.
	To comply with the provisions of ASC 820, we incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements.  In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.
	Although we have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by ourselves and our counterparties.  However, as of March 31, 2015, we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and have determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives.  As a result, we have determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.
	The table below sets forth the estimated fair value of our interest rate swaps as of March 31, 2015 and December 31, 2014, which we measure on a recurring basis by level within the fair value hierarchy.
			Fair Value Measurement Using

	Financial Instruments Disclosed at Fair Value
	The carrying amounts of cash and cash equivalents, rents and other receivables, other assets, accounts payable, accrued expenses and other liabilities, and tenant security deposits approximate fair value because of their short-term nature.
	The fair value of our notes payable was estimated by calculating the present value of principal and interest payments, using currently available market rates, adjusted with a credit spread, and assuming the loans are outstanding through contractual maturity date.

	Legal
	From time to time, we are subject to various legal proceedings that arise in the ordinary course of business.
	On October 3, 2013, two pre-IPO investors filed a putative class action purportedly brought on behalf of the investors in RIF III in the Los Angeles County Superior Court. On February 14, 2014, a First Amended Complaint was filed adding an additional individual pre-IPO investor and putative class claims on behalf of investors in RIF IV.  This complaint also alleged that the communication of the proposed accommodation (in which Messrs. Schwimmer, Frankel and Ziman, together with certain other pre-IPO owners of the pre-IPO management companies agreed to return up to $32.1 million that they received in connection with our IPO and formation transactions) was materially misleading by not including disclosures regarding the lawsuit and claims asserted by plaintiffs.  On July 15, 2014, a Second Amended Complaint was filed withdrawing the class action allegations and the allegations concerning communication of the accommodation, and adding four additional plaintiff investors. During the third quarter of 2014, the Company entered into settlement agreements with three of these four additional plaintiffs.  The aggregate amounts paid by the Company in these settlements were not material. Plaintiffs asserted claims against the Company, RIF III, RIF IV, RILLC and Messrs. Schwimmer, Frankel and Ziman for breach of fiduciary duty, violation of certain California securities laws, negligent misrepresentation, and fraud. Plaintiffs alleged, among other things, that the terms of the Company’s formation transactions were unfair to investors in RIF III and RIF IV, that the consideration received by investors in RIF III and RIF IV in the formation transactions was inadequate, that the pre-IPO management companies were allocated unfair value in the formation transactions and that the disclosure documents related to the formation transactions were materially misleading.  Plaintiffs also requested to inspect the books and records of RIF III and RIF IV, which entities no longer exist, and further sought declaratory relief, unspecified recessionary damages, disgorgement, compensatory, punitive and exemplary damages, an accounting for unjust enrichment, and an award of costs including pre-judgment interest, attorneys’ and experts’ fees, and other unspecified relief. Defendants answered the Second Amended Complaint denying all allegations and asserting affirmative defenses.  During the second quarter of 2015, the Company entered into a settlement agreement with the remaining plaintiffs.  The aggregate amount paid by the Company in this settlement was not material.
	Environmental
	We generally will perform environmental site assessments at properties we are considering acquiring.  After the acquisition of such properties, we continue to monitor the properties for the presence of hazardous or toxic substances. From time to time, we acquire properties with known adverse environmental conditions.  If at the time of acquisition, losses associated with environmental remediation obligations are probable and can be reasonably estimable, we record a liability.
	On February 25, 2014, we acquired the property located at West 228th Street.  Before purchasing the property, during the due diligence phase, we engaged with a third party environmental consultant to perform various environmental site assessments to determine the presence of any environmental contaminants that might warrant remediation efforts. Based on their investigation, they determined that hazardous substances existed at the property and that additional assessment and remediation work would likely be required to satisfy regulatory requirements.  The total remediation costs were estimated to be $1.3 million.
	To address the estimated costs associated with the environmental issues at the West 228th Street property, we entered into an Environmental Holdback Escrow Agreement (the “Holdback Agreement”) with the former owner, whereby $1.3 million of the purchase price, which would have otherwise been paid to the former owner, was to be placed into an escrow account to be used to pay remediation costs.  In addition, we also funded $100,000 into the escrow account.  According to the Holdback Agreement, the seller has no liability or responsibility to pay for remediation costs in excess of $1.3 million.
	As of March 31, 2015 and December 31, 2014, we have a $1.2 million contingent liability recorded in our consolidated balance sheets included in the line item “Accounts payable accrued expenses and other liabilities”, reflecting the estimated remaining cost to remediate environmental liabilities that existed prior to the acquisition date.  As of March 31, 2015 and December 31, 2014, we also have a $1.2 million corresponding indemnification asset recorded in our consolidated balance sheets included in the line item “Other assets”, reflecting the estimated costs we expect the former owner to cover pursuant to the Holdback Agreement.
	We expect that the resolution of the environmental matters relating to the above will not have a material impact on our consolidated financial condition, results of operations or cash flows.  However, we cannot assure you that we have identified all environmental liabilities at our properties, that all necessary remediation actions have been or will be undertaken at our properties or that we will be indemnified, in full or at all, in the event that such environmental liabilities arise.  Furthermore, we cannot assure you that future changes to environmental laws or regulations and their application will not give rise to loss contingencies for future environmental remediation.
	Rent Expense
	As of March 31, 2015, we lease a parcel of land that is currently being sub-leased to a tenant for a parking lot.  The ground lease is scheduled to expire on June 1, 2062.
	The future minimum commitment under our ground lease and corporate office lease as of March 31, 2015 is as follows:
			Office Lease		Ground Rent
	April 1, 2015 - December 31, 2015		$	337,000	$	108,000
	2016			520,000		144,000

	Thereafter			-		6,108,000
	Total		$	2,295,000	$	6,792,000
	Tenant and Construction Related
	As of March 31, 2015, we had commitments of approximately $4.1 million for tenant improvement and construction work under the terms of leases with certain of our tenants and contractual agreements with our construction vendors.
	Concentrations of Credit Risk
	We have deposited cash with financial institutions that are insured by the Federal Deposit Insurance Corporation up to $250,000 per institution.  Although we have deposits at institutions in excess of federally insured limits as of March 31, 2015, we do not believe we are exposed to significant credit risk due to the financial position of the institutions in which those deposits are held.
	As of March 31, 2015, all of our properties are located in the Southern California infill markets.  The ability of the tenants to honor the terms of their respective leases is dependent upon the economic, regulatory and social factors affecting the markets in which the tenants operate.
	As of March 31, 2015, our 10 largest tenants represented approximately 14% of our annualized base rent, which is based on the monthly contracted base rent from leases in effect as of March 31, 2015, multiplied by 12, excluding billboard and antenna revenue and rent abatements.   During the three months ended March 31, 2015, no single tenant accounted for more than 10% of our rental revenues.

Equity [Abstract]
Equity	14	Equity
	Common Stock
	On February 3, 2015, we completed a public follow-on offering of 11,500,000 shares of our common stock at a public offering price of $16.00 per share.  The net proceeds of the follow-on offering were approximately $176.3 million, after deducting the underwriting discount and offering costs paid and accrued aggregating approximately $7.7 million.  On February 3, 2015, we contributed the net proceeds of the offering to our Operating Partnership in exchange for 11,500,000 common units of partnership interests in the Operating Partnership (“OP Units”).
	Noncontrolling Interests
	Noncontrolling interests in our Operating Partnership relate to interests in the partnership that are not owned by us. Noncontrolling interests consisted of 2,296,686 OP Units and represented approximately 4.0% of our Operating Partnership as of March 31, 2015. OP Units and shares of our common stock have essentially the same economic characteristics, as they share equally in the total net income or loss and distributions of our Operating Partnership. Investors who own OP Units have the right to cause our Operating Partnership to redeem any or all of their units in our Operating Partnership for an amount of cash per unit equal to the then current market value of one share of common stock, or, at our election, shares of our common stock on a one-for-one basis.
	During the three months ended March 31, 2015, 26,658 OP Units were converted into an equivalent number of shares of common stock, resulting in the reclassification of $297,000 of noncontrolling interest to Rexford Industrial Realty, Inc.’s stockholders equity.
	2013 Incentive Award Plan
	In July 2013, we established the Rexford Industrial Realty, Inc. and Rexford Industrial Realty, L.P. 2013 Incentive Award Plan (the “Plan”), pursuant to which we may make grants of stock options, restricted stock, long term incentive plan units in our Operating Partnership and other stock based and cash awards to our non-employee directors, employees and consultants. The maximum number of shares of our common stock that may be issued or transferred pursuant to the Plan is 2,272,689 shares (of which 1,818,389 shares of common stock remain available for issuance as of March 31, 2015).
	Shares of our restricted common stock generally may not be sold, pledged, assigned or transferred in any manner other than by will or the laws of descent and distribution or, subject to the consent or the administrator of the Plan, a domestic relations order, unless and until all restrictions applicable to such shares have lapsed. Such restrictions generally expire upon vesting. Shares of our restricted common stock have full voting rights and rights to dividends.
	During the three months ended March 31, 2015 and 2014, we recognized net equity compensation expense of $367,000 and $172,000, respectively, related to the restricted common stock grants ultimately expected to vest. Equity compensation expense is included in general and administrative and property expenses in the accompanying consolidated statements of operations. Certain amounts of equity compensation expense are capitalized for employees who provide leasing and construction services. During the three months ended March 31, 2015 and 2014, we capitalized $18,000 and $29,000 respectively, related to these employees.
	The following table sets forth our nonvested restricted stock activity for the three months ended March 31, 2015:
			Number of Nonvested Shares of Restricted Common Stock
	Balance at January 1, 2015			320,017
	Granted			108,699
	Forfeited			(8,436	)
	Vested			-
	Balance at March 31, 2015			420,280
	The following table sets forth the vesting schedule of total nonvested shares of restricted stock outstanding as of March 31, 2015:
			Shares
	April 1, 2015 - December 31, 2015			106,754
	2016			112,232
	2017			140,007
	2018			42,266
	2019			19,021
				420,280
	As of March 31, 2015, there was approximately $4.5 million of total unrecognized compensation expense related to nonvested shares of our restricted common stock expected to vest, of which approximately $0.3 million will be capitalized for employees who provide leasing and construction services. As of March 31, 2015, this total unrecognized compensation expense is expected to be recognized over a weighted average remaining period of 40 months.

	On April 1, 2015, we repaid the $10.1 million outstanding balance on our loan secured by the property located at 2980-2990 North San Fernando Road.  We repaid the balance using available cash on hand and did not incur any prepayment penalties for repaying in advance of the maturity date of July 1, 2015.
	In April 2015, the Company entered into separate Equity Distribution Agreements (the “Agreements”) with each of Wells Fargo Securities, LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, Citigroup Global Markets Inc. and J.P. Morgan Securities LLC (the “Sales Agents”). Under the terms of the Agreements, the Company may issue and sell from time to time through or to the Sales Agents, as sales agents and/or principals, shares of the Company’s common stock having an aggregate offering amount of up to $125.0 million.
	On April 30, 2015, we acquired the property located at 9615 S. Norwalk Boulevard in Santa Fe Springs, California for a contract price of $9.6 million using available cash on hand.  The property consists of a 10 acre paved land storage facility and includes a 26,362 square foot industrial building and a 12,000 square foot office building.
	On May 1, 2015, we acquired the property located at 16221 Arthur Street in Cerritos, California for a contract price of $5.8 million using available cash on hand.  The property consists of one single-tenant building totaling 61,372 rentable square feet.
	Subsequent to March 31, 2015, 27,614 OP Units were converted into an equivalent number of shares of common stock.

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2015
Accounting Policies [Abstract]
Cash and Cash Equivalents	Cash and Cash Equivalents
	Cash and cash equivalents include all cash and liquid investments with an initial maturity of three months or less. The carrying amount approximates fair value due to the short term maturity of these investments.
Discontinued Operations	Discontinued Operations
	On April 14, 2014, the FASB issued Accounting Standards Update 2014-08: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (“ASU 2014-08”).  Under ASU 2014-08, only disposals that represent a strategic shift that has (or will have) a major effect on the entity’s results and operations would qualify as discontinued operations. ASU 2014-08 further expands the disclosure requirements for disposals that meet the definition of a discontinued operation, and requires entities to disclose information about disposals of individually significant components.  We elected to adopt ASU 2014-08 early, beginning in the fiscal quarter ended September 30, 2014.  The adoption of ASU 2014-08 has and will likely result in fewer property sales being classified as discontinued operations.
	During the three months ended March 31, 2014, we sold two of our operating properties.  As these properties were sold and classified as held for sale prior to the adoption of ASU 2014-08, the revenues and expenses of these properties are reported as discontinued operations in the consolidated statements of operations for all periods presented through the date of the disposition.  Furthermore, the gain (loss) on sale of these properties is reported as discontinued operations in the consolidated statements of operations in the period the properties are sold. See Note 13.
Investment in Real Estate	Investment in Real Estate
	Acquisitions
	When we acquire operating properties, with the intention to hold the investment for the long-term, we allocate the purchase price to the various components of the acquisition based upon the fair value of each component. The components typically include land, building and improvements, intangible assets related to above and below market leases, intangible assets related to in-place leases, debt and other assumed assets and liabilities.  The initial allocation of the purchase price is based on management’s preliminary assessment, which may differ when final information becomes available. Subsequent adjustments made to the initial purchase price allocation are made within the allocation period, which typically does not exceed one year.
	We allocate the purchase price to the fair value of the tangible assets by valuing the property as if it were vacant. We consider Level 3 inputs, which are unobservable inputs based on the Company’s assumptions about the assumptions a market participant would use, such as the replacement cost of such assets, appraisals, property condition reports, comparable market rental data and other related information.
	In determining the fair value of intangible lease assets or liabilities, we also consider Level 3 inputs. Acquired above and below market leases are valued based on the present value of the difference between prevailing market rates and the in-place rates measured over a period equal to the remaining term of the lease for above market leases and the initial term plus the term of any below market fixed rate renewal options for below market leases, if applicable.  The estimated fair value of acquired in-place at-market tenant leases are the costs that would have been incurred to lease the property to the occupancy level of the property at the date of acquisition. Such estimates include the value associated with leasing commissions, legal and other costs, as well as the estimated period necessary to lease such property that would be incurred to lease the property to its occupancy level at the time of its acquisition. Acquisition costs associated with the business combination are expensed in the period they are incurred.
	The difference between the fair value and the face value of debt assumed in connection with an acquisition is recorded as a premium or discount and amortized to “interest expense” over the life of the debt assumed. The valuation of assumed liabilities is based on our estimate of the current market rates for similar liabilities in effect at the acquisition date.
	For acquisitions that do not meet the accounting criteria to be accounted for as a business combination, we record to land and building the purchase price paid and capitalize the associated acquisition costs.  We capitalized $36,000 and $42,000 in acquisition costs during the three months ended March 31, 2015 and 2014, respectively.  See Note 3.
	Capitalization of Costs
	We capitalize costs incurred in developing, renovating, rehabilitating, and improving real estate assets as part of the investment basis. Costs incurred in making repairs and maintaining real estate assets are expensed as incurred. During the land development and construction periods, we capitalize interest, insurance, real estate taxes and certain general and administrative costs, including direct payroll, bonus and noncash equity compensation, of the personnel performing development, renovations, and rehabilitation if such costs are incremental and identifiable to a specific activity to get the asset ready for its intended use. Capitalized costs are included in the investment basis of real estate assets.
	Depreciation and Amortization
	Real estate, including land, building and land improvements, tenant improvements, and furniture, fixtures and equipment, leasing costs and intangible lease assets and liabilities are stated at historical cost less accumulated depreciation and amortization, unless circumstances indicate that the cost cannot be recovered, in which case, the carrying value of the property is reduced to estimated fair value as discussed below in our policy with regards to impairment of long-lived assets. We estimate the depreciable portion of our real estate assets and related useful lives in order to record depreciation expense. Our ability to estimate the depreciable portions of our real estate assets and useful lives is critical to the determination of the appropriate amount of depreciation and amortization expense recorded and the carrying value of the underlying assets. Any change to the assets to be depreciated and the estimated depreciable lives of these assets would have an impact on the depreciation expense recognized.
	The values allocated to buildings, site improvements, in-place leases, tenant improvements and leasing costs are depreciated on a straight-line basis using an estimated remaining life of 10-30 years for buildings, 20 years for site improvements, and the shorter of the estimated useful life or respective lease term for tenant improvements.
	As discussed above in investments in real estate, in connection with property acquisitions, we may acquire leases with rental rates above or below the market rental rates. Such differences are recorded as an intangible lease asset or liability and amortized to “rental revenues” over the reasonably assured term of the related leases. The unamortized balances of these assets and liabilities associated with the early termination of leases are fully amortized to their respective revenue line items in our consolidated financial statements over the shorter of the expected life of such assets and liabilities or the remaining lease term.
	Our estimate of the useful life of our assets is evaluated upon acquisition and when circumstances indicate a change in the useful life, which requires significant judgment regarding the economic obsolescence of tangible and intangible assets.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets
	In accordance with the provisions of the Impairment or Disposal of Long-Lived Assets Subsections of ASC Topic 360: Property, Plant, and Equipment, we assess the carrying values of our respective long-lived assets, including goodwill, whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable.
	Recoverability of real estate assets is measured by comparison of the carrying amount of the asset to the estimated future undiscounted cash flows. In order to review real estate assets for recoverability, we consider current market conditions as well as our intent with respect to holding or disposing of the asset. The intent with regards to the underlying assets might change as market conditions and other factors change. Fair value is determined through various valuation techniques; including discounted cash flow models, applying a capitalization rate to estimated net operating income of a property, quoted market values and third party appraisals, where considered necessary. The use of projected future cash flows is based on assumptions that are consistent with estimates of future expectations and the strategic plan used to manage our underlying business. If our analysis indicates that the carrying value of the real estate asset is not recoverable on an undiscounted cash flow basis, we will recognize an impairment charge for the amount by which the carrying value exceeds the current estimated fair value of the real estate property.
	Assumptions and estimates used in the recoverability analyses for future cash flows, discount rates and capitalization rates are complex and subjective. Changes in economic and operating conditions or our intent with respect to our investment that occur subsequent to our impairment analyses could impact these assumptions and result in future impairment of our real estate properties.
Investment in Unconsolidated Real Estate	Investment in Unconsolidated Real Estate
	Investments in unconsolidated real estate in which we have the ability to exercise significant influence (but not control) are accounted for under the equity method of investment.  Under the equity method, we initially record our investment at cost, and subsequently adjust for equity in earnings or losses and cash contributions and distributions. Any difference between the carrying amount of these investments on the balance sheet and the underlying equity in net assets is amortized as an adjustment to equity in income (loss) from unconsolidated real estate over the life of the related asset. Under the equity method of accounting, our net equity investment is reflected within the consolidated balance sheets, and our share of net income or loss from the joint ventures is included within the consolidated statements of operations.  See Note 12.
Income Taxes	Income Taxes
	We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”) commencing with our initial taxable year ended December 31, 2013. To qualify as a REIT, we are required (among other things) to distribute at least 90% of our REIT taxable income to our stockholders and meet the various other requirements imposed by the Code relating to matters such as operating results, asset holdings, distribution levels and diversity of stock ownership. Provided we qualify for taxation as a REIT, we are generally not subject to corporate-level income tax on the earnings distributed currently to our stockholders that we derive from our REIT qualifying activities. If we fail to qualify as a REIT in any taxable year, and were unable to avail ourselves of certain savings provisions set forth in the Code, all of our taxable income would be subject to federal income tax at regular corporate rates, including any applicable alternative minimum tax.
	In addition, we are subject to taxation by various state and local jurisdictions, including those in which we transact business or reside. Our non-taxable REIT subsidiaries, including our Operating Partnership, are either partnerships or disregarded entities for federal income tax purposes. Under applicable federal and state income tax rules, the allocated share of net income or loss from disregarded entities (including limited partnerships and S-Corporations) is reportable in the income tax returns of the respective partners and stockholders. Accordingly, no income tax provision is included in the accompanying consolidated financial statements for the three months ended March 31, 2015 and 2014.
	We periodically evaluate our tax positions to determine whether it is more likely than not that such positions would be sustained upon examination by a tax authority for all open tax years, as defined by the statute of limitations, based on their technical merits. As of March 31, 2015 and December 31, 2014, we have not established a liability for uncertain tax positions.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities
	FASB ASC Topic 815: Derivatives and Hedging (“ASC 815”), provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments.
	As required by ASC 815, we record 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, and whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. 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.  We may enter into derivative contracts that are intended to economically hedge certain risks, even though hedge accounting does not apply or we elect not to apply hedge accounting.  See Note 8.
Revenue Recognition	Revenue Recognition
	We recognize revenue from rent, tenant reimbursements and other revenue sources once all of the following criteria are met: persuasive evidence of an arrangement exists, the delivery has occurred or services rendered, the fee is fixed and determinable and collectability is reasonably assured. Minimum annual rental revenues are recognized in rental revenues on a straight-line basis over the term of the related lease. Rental revenue recognition commences when the tenant takes possession or controls the physical use of the leased space.
	Estimated reimbursements from tenants for real estate taxes, common area maintenance and other recoverable operating expenses are recognized as revenues in the period that the expenses are incurred. Subsequent to year-end, we perform final reconciliations on a lease-by-lease basis and bill or credit each tenant for any cumulative annual adjustments. Lease termination fees, which are included in rental revenues in the accompanying consolidated statements of operations, are recognized when the related lease is canceled and we have no continuing obligation to provide services to such former tenant.
	Revenues from management, leasing and development services are recognized when the related services have been provided and earned.
	The recognition of gains on sales of real estate requires us to measure the timing of a sale against various criteria related to the terms of the transaction, as well as any continuing involvement in the form of management or financial assistance associated with the property. If the sales criteria are not met, we defer gain recognition and account for the continued operations of the property by applying the finance, profit-sharing or leasing method. If the sales criteria have been met, we further analyze whether profit recognition is appropriate using the full accrual method. If the criteria to recognize profit using the full accrual method have not been met, we defer the gain and recognize it when the criteria are met or use the installment or cost recovery method as appropriate under the circumstances. See Note 13 for discussion of dispositions.
Valuation of Receivables	Valuation of Receivables
	We are subject to tenant defaults and bankruptcies that could affect the collection of outstanding receivables. In order to mitigate these risks, we perform credit reviews and analyses on prospective tenants before significant leases are executed and on existing tenants before properties are acquired. We specifically analyze aged receivables, customer credit-worthiness, historical bad debts and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. As a result of our periodic analysis, we maintain an allowance for estimated losses that may result from the inability of our tenants to make required payments. This estimate requires significant judgment related to the lessees’ ability to fulfill their obligations under the leases. We believe our allowance for doubtful accounts is adequate for our outstanding receivables for the periods presented. If a tenant is insolvent or files for bankruptcy protection and fails to make contractual payments beyond any allowance, we may recognize additional bad debt expense in future periods equal to the net outstanding balances, which include amounts recognized as straight-line revenue not realizable until future periods. We recorded a provision for doubtful accounts of approximately $0.4 million and $0.4 million for the three months ended March 31, 2015 and 2014, respectively, as a reduction to rental revenues in our consolidated statements of operations. We had a $1.3 million and $1.0 million reserve for allowance for doubtful accounts as of March 31, 2015 and December 31, 2014, respectively.
Equity Based Compensation	Equity Based Compensation
	We account for equity-based compensation, including shares of restricted stock, in accordance with ASC Topic 718 Compensation – Stock Compensation.  For share-based awards that vest based solely on a service condition, we recognize compensation cost on a straight-line basis over the total requisite service period for the entire award.  The total compensation expense for these awards is based upon the fair market value of the shares on the grant date, adjusted for estimated forfeitures.  See Note 14.
Equity Offering Costs	Equity Offering Costs
	Underwriting commissions and offering costs have been reflected as a reduction of additional paid-in capital.
Earnings Per Share	Earnings Per Share
	We calculate earnings per share (“EPS”) in accordance with ASC 260 – Earnings Per Share (“ASC 260”).  Under ASC 260, shares of unrestricted stock that contain non-forfeitable rights to dividends are participating securities and, therefore, are included in computing basic EPS pursuant to the two-class method. The two-class method determines EPS for each class of common stock and participating securities according to dividends declared (or accumulated) and their respective participation rights in undistributed earnings.
	Basic EPS is calculated by dividing the net income (loss) attributable to common stockholders by the weighted average shares of common stock outstanding for the period. Diluted EPS is computed using the weighted average shares of common stock outstanding determined for the basic EPS computation plus the effect of any dilutive securities, including the dilutive effect of unvested restricted common stock using the treasury stock method. See Note 15.
Segment Reporting	Segment Reporting
	Management views the Company as a single reportable segment based on its method of internal reporting in addition to its allocation of capital and resources.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements
	Changes to GAAP are established by the FASB in the form of ASUs to the FASB’s Accounting Standards Codification. We consider the applicability and impact of all ASUs.
	On April 7, 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (“ASU 2015-03”).  ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a reduction from the carrying value of the debt liability. This offset against the debt liability is treated similarly to a debt discount, which effectively reduces the proceeds of a borrowing. ASU 2015-03 is effective for annual and interim periods beginning on or after December 15, 2015, with early adoption permitted on a retrospective basis.  We have elected to adopt ASU 2015-03 early, beginning with the current quarter ended March 31, 2015.  As a result of the adoption of ASU 2015-03, we have reclassified approximately $0.7 million of net debt issuance costs from an asset (previously recorded in the line item “Deferred loan costs, net” in the consolidated balance sheets) to a reduction in the carrying amount of our notes payable as of December 31, 2014.  ASU 2015-03 also expands disclosure requirements to include the face amount of the debt liability and the effective interest rate in the notes to the consolidated financial statements.  See Note 6.
	In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis ("ASU 2015-02"). ASU 2015-02 requires reporting entities to evaluate whether they should consolidate certain legal entities.  ASU 2015-02 modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (“VIEs”) or voting interest entities and eliminates the presumption that a general partner should consolidate a limited partnership. This ASU affects the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships. ASU 2015-02 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. A reporting entity may apply the amendments in the ASU using: (i) a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption; or (ii) by applying the amendments retrospectively. We are currently assessing the potential impact that the adoption of the ASU 2015-02 will have on our consolidated financial statements.
	On May 28, 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”).  ASU 2014-09 establishes principles for reporting the nature, amount, timing and uncertainty of revenues and cash flows arising from an entity's contracts with customers. The core principle of the new standard is that an entity recognizes revenue to represent the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This standard is effective for us in the first quarter of 2017 and will replace most existing revenue recognition guidance within GAAP. Early adoption is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We are currently evaluating ASU 2014-09 to determine its impact on our consolidated financial statements and related disclosures, as well as the transition method to apply the new standard.
