Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization	Note 1 - Organization
	DCT Industrial Trust Inc. is a leading industrial real estate company specializing in the acquisition, development, leasing and management of bulk distribution and light industrial properties located in high-volume distribution markets in the United States (“U.S.”). As used herein, the terms “Company,” “we,” “our” and “us” refer to DCT Industrial Trust Inc. and its subsidiaries, including its operating partnership, DCT Industrial Operating Partnership LP. When we use the term “DCT,” we are referring to DCT Industrial Trust Inc. by itself, and not including any of its subsidiaries, and when we use the term the “Operating Partnership,” we are referring to DCT Industrial Operating Partnership LP by itself, and not including any of its subsidiaries.
	DCT was formed as a Maryland corporation in April 2002 and has elected to be treated as a real estate investment trust, or REIT, for U.S. federal income tax purposes. We are structured as an umbrella partnership REIT under which substantially all of our current and future business is, and will be, conducted through a majority owned and controlled subsidiary, DCT Industrial Operating Partnership LP, a Delaware limited partnership, for which DCT is the sole general partner. DCT owns properties through the Operating Partnership and its subsidiaries. As of December 31, 2014, DCT owned approximately 95.4% of the outstanding equity interests in the Operating Partnership.
	On November 17, 2014, we completed a one-for-four reverse stock split of our issued and outstanding common stock and a corresponding reverse split of the partnership interests of the Operating Partnership.  The number of authorized shares and the par value of the common stock were not changed.  All common stock/unit and per share/unit data for all periods presented in this Annual Report on Form 10-K have been restated to give effect to the reverse stock split
	As of December 31, 2014, the Company owned interests in approximately 72.3 million square feet of properties leased to approximately 900 customers, including:
	—	62.0 million square feet comprising 393 consolidated operating properties were 95.4% occupied;

Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	Note 2 - Summary of Significant Accounting Policies
	Basis of Presentation and Principles of Consolidation
	The accompanying Consolidated Financial Statements include the financial position, results of operations and cash flows of the Company, the Operating Partnership, their wholly-owned qualified REIT subsidiaries and taxable REIT subsidiaries, and their consolidated joint ventures, in which they have a controlling interest.
	Equity interests in the Operating Partnership held by entities other than DCT are classified within partners’ capital in the Operating Partnership’s financial statements and as noncontrolling interests in DCT’s financial statements. Equity interests in entities consolidated into the Operating Partnership that are held by third parties are reflected in our accompanying balance sheets as noncontrolling interests in consolidated entities. We also have noncontrolling partnership interests in unconsolidated institutional capital management and other joint ventures, which are accounted for under the equity method. All significant intercompany transactions and balances have been eliminated in consolidation.
	All square feet, acres, occupancy, number of properties, number of customers and total projected investment disclosed in the notes to the Consolidated Financial Statements are unaudited.
	We hold interests in both consolidated and unconsolidated joint ventures. All joint ventures over which we have financial and operating control, and variable interest entities (“VIEs”) in which we have determined that we are the primary beneficiary, are included in the Consolidated Financial Statements. We use the equity method of accounting for joint ventures over which we do not have a controlling interest or where we do not exercise significant control over major operating and management decisions but where we exercise significant influence and include our share of earnings or losses of these joint ventures in our consolidated results of operations.
	We analyze our joint ventures in accordance with generally accepted accounting principles (“GAAP”) to determine whether they are VIEs and, if so, whether we are the primary beneficiary. Our judgment with respect to our level of influence or control over an entity and whether we are the primary beneficiary of a VIE involves consideration of various factors including the form of our ownership interest, our representation on the entity’s board of directors, the size of our investment (including loans) and our ability to participate in major decisions. Our ability to correctly assess our influence or control over an entity affects the presentation of these investments in the Consolidated Financial Statements and, consequently, our financial position and results of operations.
	Use of Estimates
	The preparation of the Consolidated Financial Statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	Capitalization of Costs
	We capitalize costs directly related to the development, pre-development, redevelopment or improvement of our investment in real estate, referred to as capital projects and other activities included within this paragraph. Costs associated with our capital projects are capitalized as incurred. If the project is abandoned, these costs are expensed during the period in which the project is abandoned. Costs considered for capitalization include, but are not limited to, construction costs, interest, real estate taxes and insurance, if appropriate. We capitalize indirect costs such as personnel, office and administrative expenses that are directly related to our development projects based on an estimate of the time spent on the construction and development activities. These costs are capitalized only during the period in which activities necessary to ready an asset for its intended use are in progress and such costs are incremental and identifiable to a specific activity to get the asset ready for its intended use. We determine when the capitalization period begins and ends through communication with project and other managers responsible for the tracking and oversight of individual projects. In the event that the activities to ready the asset for its intended use are suspended, the capitalization period will cease until such activities are resumed. In addition, we capitalize initial direct costs incurred for successful origination of new leases. Costs incurred for maintaining and repairing our properties, which do not extend their useful lives, are expensed as incurred.
	Interest is capitalized based on actual capital expenditures from the period when development or redevelopment commences until the asset is ready for its intended use, at the weighted average borrowing rate during the period. We also capitalize interest on our qualifying investments in unconsolidated joint ventures based on the average capital invested in a venture during the period when the venture has activities in progress necessary to commence its planned principal operations, at our weighted average borrowing rate during the period. A “qualifying investment” is an investment in an unconsolidated joint venture provided that our investee’s activities include the use of funds to acquire qualifying assets, such as development or predevelopment activities, and planned principal operations have not commenced.
	Discontinued Operations and Assets Held for Sale
	We classify certain properties and related assets and liabilities as held for sale when certain criteria are met. At such time, the respective assets and liabilities are presented separately on our Consolidated Balance Sheets. We include liabilities related to assets held for sale that will be transferred in the transaction in “Liabilities related to assets held for sale.” Assets held for sale are reported at the lower of carrying value or estimated fair value less estimated costs to sell.
	Effective January 1, 2014, we adopted accounting standard update (“ASU”) No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, for all properties not previously sold or classified as held for sale.  ASU 2014-08 revised the reporting requirements to only allow a component of an entity, or group of components of an entity, to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results.  Prior to January 1, 2014, properties identified as held for sale and/or disposed of are presented in discontinued operations for all periods presented.
	Gains on sales of real estate assets are recognized if the specific transaction terms meet the various sale recognition criteria as defined by GAAP. If the criteria are not met, we defer the gain until such time that the criteria for sale recognition have been met. Net gains on sales and any impairment losses associated with assets held for sale are presented in continuing operations when recognized.
	Fair Value
	GAAP establishes a framework for measuring fair value and requires disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants. The guidance establishes a hierarchy for inputs used in measuring fair value based on observable and unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are based on market data obtained from sources independent of DCT. Unobservable inputs are inputs that reflect our assumptions of pricing the asset or liability based on the best information available in the circumstances. The hierarchy is broken down into three levels as follows:
	Level 1: Inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets;
	Level 2: Inputs include quoted prices for similar assets and liabilities in active or inactive markets or that are observable either directly or indirectly for the asset or liability; and
	Level 3: Unobservable inputs are typically based on management’s own assumptions, as there is little, if any, related observable market activity.
	DCT’s assets and liabilities that are measured at fair value are classified in their entirety based on the lowest level of input that is significant to their fair value measurement. Our 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.
	Investment in Properties
	We record the assets, liabilities and noncontrolling interests associated with property acquisitions which qualify as business combinations at their respective acquisition date fair values which are derived using a market, income or replacement cost approach, or combination thereof. Acquisition related costs associated with business combinations are expensed as incurred. As defined by GAAP, a business is an integrated set of activities and assets that is capable of being conducted and managed for the purpose of providing a return in the form of dividends, lower costs or other economic benefits directly to investors or other owners, members or participants. We do not consider acquisitions of land or unoccupied buildings to be business combinations. Rather, these transactions are treated as asset acquisitions and recorded at cost.
	The fair value of identifiable tangible assets such as land, building, building and land improvements, and tenant improvements is determined on an “as-if-vacant” basis. Management considers Level 3 inputs such as the replacement cost of such assets, appraisals, property condition reports, market data and other related information in determining the fair value of the tangible assets. 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 the current market rate for similar liabilities. The recorded fair value of intangible lease assets includes Level 3 inputs and represents the value associated with in-place leases which include leasing commissions, legal and other costs, as well as an intangible asset or liability resulting from in-place leases being above or below the market rental rates over the lease term on the date of the acquisition. Intangible lease assets or liabilities are amortized over the reasonably assured lease term of the remaining in-place leases as an adjustment to “Rental revenues” or “Real estate related depreciation and amortization” depending on the nature of the intangible.
	We have certain properties which we have acquired or removed from service with the intention to redevelop the property. Buildings under redevelopment require significant construction activities prior to being placed back into service. We generally do not depreciate properties classified as redevelopment until the date that the redevelopment properties are ready for their intended use.
	Real estate, including land, building, building and land improvements, tenant improvements, 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 its estimated fair value.
	Depreciation and Useful Lives of Real Estate Assets
	Depreciation and amortization are computed on a straight-line basis over the estimated useful lives of the related assets or liabilities. Our ability to assess the useful lives of our real estate assets accurately is critical to the determination of the appropriate amount of depreciation and amortization expense recorded and the carrying values of the underlying assets. Any change to the estimated depreciable lives of these assets would have an impact on the depreciation and amortization expense we recognize.
	The following table reflects the standard depreciable lives generally used to compute depreciation and amortization. However, such depreciable lives may be different based on the estimated useful life of such assets or liabilities. The carrying value of assets sold or retired and the related accumulated depreciation and/or amortization is derecognized and the resulting gain or loss, if any, is recorded during the period in which such sale or retirement occurs.
	Description	Expected Useful Life
	Land	Not depreciated
	Building	20 – 40 years
	Building and land improvements	5 – 20 years
	Tenant improvements	Shorter of lease term or useful life
	Leasing costs	Lease term
	Other intangible lease assets	Average term of leases for property
	Above/below market rent assets/liabilities	Reasonably assured lease term
	Depreciation is not recorded on real estate assets currently held for sale, in pre-development, or being developed or redeveloped until the building is substantially completed and ready for its intended use, not later than one year from cessation of major construction activity.
	Impairment of Properties
	Investments in properties classified as held for use are carried at cost and evaluated for impairment at least annually and whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be recoverable. Examples of such changes in circumstances include the point at which we deem a building to be held for sale, our intended hold period changes, or when a building remains vacant significantly longer than expected. For investments in properties that we intend to hold long-term, the recoverability is based on estimated future undiscounted cash flows. If the asset carrying value is not supported on an undiscounted cash flow basis, the amount of impairment is measured as the difference between the carrying value and the fair value of the asset and is reflected in “Impairment losses” on the Consolidated Statements of Operations. The determination of fair value of real estate assets to be held for use is derived using the discounted cash flow method and involves a number of management assumptions relating to future economic events that could materially affect the determination of the ultimate value, and therefore, the carrying amounts of our real estate. Such assumptions are Level 3 inputs and include, but are not limited to, projected vacancy rates, rental rates, property operating expenses and capital expenditures. The capitalization rate is also a significant driving factor in determining the property valuation and requires management’s judgment of factors such as market knowledge, historical experience, lease terms, customer financial strength, economy, demographics, environment, property location, visibility, age, physical condition and expected return requirements, among other things. The aforementioned factors are taken as a whole by management in determining the valuation of investment property. The valuation is sensitive to the actual results of any of these uncertain factors, either individually or taken as a whole. Should the actual results differ from management’s estimates, the valuation could be negatively affected and may result in additional impairment losses recorded in the Consolidated Financial Statements.
	Investments in and Advances to Unconsolidated Joint Ventures
	We account for our investments in and advances to unconsolidated joint ventures under the equity method because we exercise significant influence over, but do not control, these entities. Under the equity method, these investments (including advances to joint ventures) are initially recorded at cost and are subsequently adjusted to reflect our proportionate share of net earnings or losses of each of the joint ventures, distributions received, contributions made and certain other adjustments, as appropriate. Such investments are included in “Investments in and advances to unconsolidated joint ventures” in our Consolidated Balance Sheets. Distributions from these investments that are related to cash earnings from operations are included as operating activities and distributions that are related to capital transactions are included as investing activities in our Consolidated Statements of Cash Flows.
	Investment properties that were contributed to unconsolidated joint ventures prior to the adoption of ASU 2014-08 are not considered discontinued operations due to our continuing involvement through maintaining an ownership interest in these investment properties and continuing to act as manager of the assets. We recognize any gains from the contribution of investment properties into an unconsolidated joint venture if the recognition criteria have been met and the cash received is not required to be reinvested. Such gains are recognized to the extent of the outside ownership interest in the joint venture in our Consolidated Statements of Operations under the heading of “Gain on dispositions of real estate interests.” Any gain related to the remaining proceeds reduces our basis in the investment in the unconsolidated joint venture, and is recognized into earnings over the weighted average life of the related property’s real estate assets. We recognize our proportionate share of the ongoing earnings or losses of each unconsolidated joint venture in “Equity in earnings of unconsolidated joint ventures, net” in our Consolidated Statements of Operations.
	Impairment of Investments in and Advances to Unconsolidated Joint Ventures
	We evaluate our investments in unconsolidated entities for impairment whenever events or changes in circumstances indicate that there may be an other-than-temporary decline in value. To do so, we calculate the estimated fair value of the investment using a market, income or replacement cost approach, or combination thereof. The amount of impairment recognized, if any, would be the excess of the investment’s carrying amount over its estimated fair value. We consider various factors to determine if a decline in the value of the investment is other-than-temporary. These factors are Level 2 and 3 inputs and include but are not limited to, age of the venture, our intent and ability to retain our investment in the entity, the financial condition and long-term prospects of the entity, expected term of the investment and the relationships with the other joint venture partners and its lenders. If we believe that the decline in the fair value is temporary, no impairment is recorded. The aforementioned factors are taken as a whole by management in determining the valuation of our investment. Should the actual results differ from management’s estimates, the valuation could be negatively affected and may result in a negative impact on the Consolidated Financial Statements. See Note 4—Investments in and Advances to Unconsolidated Joint Ventures for additional information.
	Cash and Cash Equivalents
	Cash and cash equivalents include cash held in financial institutions and other highly liquid short-term investments with original maturities of three months or less. We have not realized any losses in our cash and cash equivalents and believe that these short-term instruments are not exposed to any significant credit risk.
	Restricted Cash
	Restricted cash consists of escrow deposits held by lenders for real estate taxes, insurance and capital replacement reserves, security deposits and amounts held by intermediary agents to be used for tax-deferred, like-kind exchange transactions.  For the year ended December 31, 2013, approximately $8.8 million of restricted cash was included in “Investing Activities” in our Consolidated Statements of Cash Flows related to tax deferred, like-kind exchange transactions.  For the year ended December 31, 2014, all funds had been utilized in tax deferred, like-kind exchange transactions.
	Deferred Loan Costs
	Deferred loan costs include fees and costs incurred to obtain long-term financing. These fees and costs are amortized to “Interest expense” over the terms of the related loans. Accumulated amortization of deferred loan costs was approximately $8.5 million and $6.3 million as of December 31, 2014 and 2013, respectively. Unamortized deferred loan costs are fully amortized when debt is retired before the maturity. Our interest expense for the years ended December 31, 2014, 2013 and 2012 includes approximately $2.2 million, $2.7 million and $2.1 million for the amortization of loan costs, respectively, including amounts related to discontinued operations.
	Straight-line Rent and Other Receivables
	Straight-line rent and other receivables include all straight-line rent and current accounts receivable, net of allowances. We maintain an allowance for estimated losses that may result from the inability of our customers to make required payments. If a customer fails to make contractual payments beyond any allowance, we may recognize additional bad debt expense in future periods equal to the net outstanding balances. As of December 31, 2014 and 2013, our allowance for doubtful accounts was approximately $1.0 million and $2.2 million, respectively.
	Debt
	Debt consists of fixed and variable rate secured mortgage notes, senior unsecured notes and bank unsecured credit facilities. Discounts and premiums to the principal amounts are included in the carrying value of debt and amortized to “Interest expense” over the remaining life of the underlying debt. The aggregated premium balance, net of accumulated amortization, was approximately $2.6 million as of December 31, 2014 and 2013.
	Derivative Instruments and Hedging Activities
	We may use interest rate swaps to manage certain interest rate risk. We record derivatives at fair value which are presented on a gross basis in “Other assets, net” or “Other liabilities” in our Consolidated Balance Sheets. 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. 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 curves. 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 us and our counterparties.
	For derivatives designated as “cash flow” hedges, the effective portion of the changes in the fair value of the derivative is initially reported in “Accumulated other comprehensive loss” in our Consolidated Balance Sheets (i.e., not included in earnings) and subsequently reclassified into earnings when the hedged transaction affects earnings or the hedging relationship is no longer effective at which time the ineffective portion of the derivative’s change in fair value is recognized directly into earnings. We assess the effectiveness of each hedging relationship whenever financial statements are issued or earnings are reported and at least every three months. We do not use derivatives for trading or speculative purposes.
	Comprehensive Income (Loss)
	We report comprehensive income (loss) in our Consolidated Statements of Comprehensive Income (Loss). Amounts reported in “Accumulated other comprehensive loss” related to settled hedging transactions will be amortized to “Interest expense” as the hedged forecasted transactions occur. Any ineffectiveness related to our hedging transactions is reported in our Consolidated Statements of Operations. See Note 6 – Financial Instruments and Hedging Activities for additional information.
	Revenue Recognition
	We record rental revenues on a straight-line basis under which contractual rent increases are recognized evenly over the lease term. Certain properties have leases that provide for tenant occupancy during periods where no rent is due or where minimum rent payments change during the term of the lease. Accordingly, we record receivables from tenants that we expect to collect over the remaining lease term rather than currently, which are recorded as a straight-line rent receivable. When we acquire a property, the terms of existing leases are considered to commence as of the acquisition date for the purposes of this calculation. The total increase to “Rental revenues” due to straight-line rent adjustments was approximately $9.9 million, $5.3 million and $6.3 million, respectively, for the years ended December 31, 2014, 2013 and 2012.
Tenant recovery income includes payments and amounts due from tenants pursuant to their leases for real estate taxes, insurance and other recoverable property operating expenses and is recognized as “Rental revenues” during the same period the related expenses are incurred. Tenant recovery income recognized as “Rental revenues” was approximately $76.5 million, $63.8 million and $51.7 million, respectively, for the years ended December 31, 2014, 2013 and 2012.
In connection with property acquisitions qualifying as business combinations, 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 Statements of Operations on a straight-line basis over the estimated remaining contractual lease term. The total net impact to “Rental revenues” due to the amortization of above and below market rents was an increase of approximately $2.4 million, $1.6 million and $0.8 million for the years ended December 31, 2014, 2013 and 2012, respectively.
Future minimum base rental payment, i.e., cash received for monthly contractual rent, due to us from our customers under the terms of non-cancelable operating leases that have commenced as of December 31, 2014 were as follows (in thousands):
Year Ended December 31,	Amounts
2015	$	248,914
2016		221,669
2017		183,342
2018		143,447
2019		112,324
Thereafter		299,406
Total	$	1,209,102
The schedule does not reflect future rental revenues from the potential renewal or replacement of existing and future leases and excludes tenant recovery income. Additionally, leases where the tenant can terminate the lease with short-term notice are not included.
Early lease termination fees are recorded in “Rental revenues” on a straight-line basis over the estimated remaining contractual lease term or upon collection if collectability is not assured. During the years ended December 31, 2014, 2013 and 2012, early lease termination fees were $2.1 million, $1.3 million and $0.6 million, respectively.
We earn revenues from asset management fees, acquisition fees, property management fees and fees for other services pursuant to joint venture and other agreements. These are included in our Consolidated Statements of Operations in “Institutional capital management and other fees.” We recognize revenues from asset management fees, acquisition fees, property management fees and fees for other services when the related fees are earned and are realized or realizable.
We develop certain properties for specific buyers, called build-to-suit projects. We make certain judgments based on the specific terms of each project as to the amount and timing of recognition of profits from the project. Projects are generally accounted for using the percentage of completion method or full accrual method. Profits under the percentage of completion method are based on our estimates of the percentage of completion of individual contracts, commencing when the work performed under the contracts reaches a point where the final costs can be estimated with reasonable accuracy. The percentage of completion estimates are based on a comparison of the contract expenditures incurred to the estimated final costs. Changes in job performance, job conditions and estimated profitability may result in revisions to the costs and income and are recognized in the period in which the revisions are determined. If the sale recognition criteria for using the percentage of completion or full accrual methods are not met, we apply another recognition method provided by GAAP, such as the installment or cost recovery methods. The profit recognized from these projects is reported net of estimated taxes, when applicable, and is included in “Development profit, net of taxes” in our Consolidated Statements of Operations.
Stock-Based Compensation
On October 10, 2006, we established the Long-Term Incentive Plan, as amended, to grant restricted stock, LTIP Units, stock options and other awards to our personnel and directors. Awards granted under this plan are measured at fair value on the grant date and amortized to compensation expense on a straight-line basis over the service period during which the awards fully vest. Such expense is included in “General and administrative” expense in our Consolidated Statements of Operations. Options issued under the Long-Term Incentive Plan are valued using the Black-Scholes option pricing model, which relies on assumptions we make related to the expected term of the options, volatility, dividend yield and risk-free interest rate.
Income and Other Taxes
We have elected to be taxed as a REIT, as defined under the Internal Revenue Code of 1986, as amended (the “Code”). As a REIT, we generally will not be subject to U.S. federal income taxes on our net income that is distributed to our stockholders if we distribute at least 90% of our REIT taxable income to our stockholders. REITs are also subject to a number of other organizational and operational requirements. If we fail to qualify as a REIT in any taxable year, our taxable income will be subject to U.S. federal income tax at regular corporate rates (including any applicable alternative minimum tax). Even if we qualify as a REIT, we may be subject to certain U.S. federal, state and local and non-U.S. income taxes. We also will be required to pay a 100% tax on non-arm’s length transactions between us and our taxable REIT subsidiary and on any net income from gain on property that was held for sale to customers in the ordinary course of business.
Certain of our operations (property management, asset ownership or management, sales of certain assets, etc.) may be conducted through taxable REIT subsidiaries, which are subsidiaries of the operating partnership and each of which we refer to as a TRS. A TRS is a C-corporation for which a REIT and its subsidiary C-corporation have jointly elected for the C-corporation to be a taxable REIT subsidiary of the REIT and therefore is subject to U.S. federal corporate income tax.
For our taxable REIT subsidiaries, deferred income taxes result from temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for U.S federal income tax purposes, as well as interest and loss carryforwards, and are measured using current enacted tax rates and laws that are expected to be in effect when the differences reverse. We reduce deferred tax assets by recording a valuation allowance when we determine based on available evidence that it is more likely than not that the assets will not be realized.
The Company recognizes penalties and interest accrued related to unrecognized tax benefits, if any, as income tax expense. To the extent interest and penalties are not assessed with respect to uncertain tax positions, amounts accrued will be reduced and reflected as a reduction of the overall income tax expense. We had no interest expense or penalties related to unrecognized tax benefits for the years ended December 31, 2014, 2013 or 2012.
We recognize tax benefits of uncertain tax positions only if it is more likely than not that the tax position will be sustained, based solely on its technical merits, with the taxing authority having full knowledge of all relevant information. The measurement of a tax benefit for an uncertain tax position that meets the “more likely than not” threshold is based on a cumulative probability model under which the largest amount of tax benefit recognized is the amount with a greater than 50% likelihood of being realized upon ultimate settlement with the taxing authority having full knowledge of all the relevant information. As of December 31, 2014 and 2013, there were no unrecognized tax benefits. We do not anticipate a significant change to the total amount of unrecognized tax benefits within the next 12 months. Our federal income tax returns and income tax returns for various state and local jurisdictions are subject to examination by the Internal Revenue Service for the year ended December 31, 2010 and subsequent years.
New Accounting Standards
In February 2013, the Financial Accounting Standards Board (the “FASB”) issued an accounting standard update that requires disclosure of the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount is required under GAAP to be reclassified in its entirety to net income. Additionally, the update requires disclosure of changes in each component of other comprehensive income (“OCI”). The disclosure requirements were retroactively effective for us on January 1, 2013. As this guidance only requires expanded disclosure, the adoption did not have any impact on our Consolidated Financial Statements.
In April 2014, the FASB issued an ASU that changes the definition of discontinued operations by limiting discontinued operations reporting to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on an entity’s operations and financial results. The amendments in the ASU should be applied prospectively and are effective for us beginning January 1, 2015, with early adoption permitted. We adopted this standard effective January 1, 2014. As a result, we anticipate that fewer of our property dispositions made in the normal course of business will qualify for discontinued operations reporting. Gains on the sale of real estate not qualifying as discontinued operations are presented in “Income (loss) from continuing operations” in our Consolidated Statements of Operations.
In May 2014, the FASB issued an ASU that requires companies to recognize revenue from contracts with customers based upon the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. The new standard also results in enhanced disclosures about revenue, provides guidance for transactions that were not previously addressed comprehensively and improves guidance for multiple-element arrangements. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is not permitted. The Company is in the process of evaluating the impact this guidance will have on its consolidated financial statements.

Equity Method Investments And Joint Ventures [Abstract]
Investments In And Advances To Unconsolidated Joint Ventures	Note 4 – Investments in and Advances to Unconsolidated Joint Ventures
	We enter into joint ventures primarily for purposes of operating and developing industrial real estate. Our investments in these joint ventures are included in “Investments in and advances to unconsolidated joint ventures” in our Consolidated Balance Sheets.
	During January 2014, the TRT-DCT Ventures I and II disposed of all their properties. We received net proceeds of approximately $6.6 million from the transactions. Based on the structure of the transactions, we recognized a gain of approximately $0.9 million on the sale of our interest in TRT-DCT Venture I, included in “Gain on dispositions of real estate interests” in our Consolidated Statements of Operations and we recognized our share of the TRT-DCT Venture II’s gain on sale of properties, approximately $2.4 million, included in “Equity in earnings of unconsolidated joint ventures, net” in our Consolidated Statements of Operations.
	During March 2014, we purchased our partner’s 50.0% interest in one building from the IDI/DCT, LLC joint venture for $10.3 million. See “Note 3 – Investment in Properties” for additional information.
	During December 2014, the IDI/DCT, LLC Venture disposed of one property.  We received net proceeds of approximately $4.1 million from the transaction and recognized our share of the venture’s gain on the sale of the property, approximately $1.0 million, included in “Equity in earnings of unconsolidated joint ventures, net” in our Consolidated Statements of Operations.

	Institutional Capital Management Joint Ventures
	DCT/SPF Industrial Operating LLC
	During 2007, we entered into a joint venture agreement with Industrial Acquisition LLC (“JP Morgan”), an entity advised by JPMorgan Asset Management, to form DCT/SPF Industrial Operating LLC (“JP Morgan Venture”) that owns and operates industrial properties located in the U.S. Our actual ownership percentage may vary depending on amounts of capital contributed and the timing of contributions and distributions. As of December 31, 2014 our ownership interest is 20.0%. As a result of our contribution of properties into the JP Morgan Venture in 2007, we have deferred gains of $2.5 million as of December 31, 2014, which will be recognized through earnings over the weighted average life of the related properties, or upon disposition of the properties to a third-party.
	TRT-DCT Industrial Joint Ventures I, II and III
	We entered into a joint venture with Dividend Capital Diversified Property Fund (“DCDPF”), formerly known as Dividend Capital Total Realty Trust Inc., to form TRT-DCT Venture I on September 1, 2006. As noted above, during 2014 the venture disposed of all of its properties.
	We formed a joint venture with DCDPF, TRT-DCT Industrial Joint Venture II G.P. (“TRT-DCT Venture II”), on March 27, 2007. As a result of our contribution of properties into TRT-DCT Venture II in 2007, we had deferred gains of $0.6 million that were recognized during 2014 upon the disposition of the ventures’ properties.
	We formed a joint venture with DCDPF, TRT-DCT Industrial Joint Venture III, G.P. (“TRT-DCT Venture III”), on September 9, 2008. Our ownership percentage may vary depending on amounts of capital contributed and the timing of contributions and distributions. As of December 31, 2014 our ownership interest is 10.0%.
	Development Projects in Unconsolidated Joint Ventures
	SCLA
	During 2006, we entered into a joint venture agreement with Stirling Airports International, LLC, (“Stirling”), an unrelated third-party, to be the master developer of up to 4,350 acres in Victorville, California, part of the Inland Empire submarket in Southern California. The development project is located at the former George Air Force Base which closed in 1992 and is now known as Southern California Logistics Airport (“SCLA”). We refer to this joint venture as the SCLA joint venture. Stirling entered into two master development agreements which gave it certain rights to be the exclusive developer of the SCLA development project through 2019 (including certain extensions) and assigned these rights to the SCLA joint venture upon the closing of the venture. While our exact share of the equity interests in the SCLA joint venture will depend on the amount of capital we contribute and the timing of contributions and distributions, the SCLA joint venture contemplates an equal sharing between us and Stirling of residual profits and cash flows after all priority distributions. As of December 31, 2014, the SCLA joint venture owned six operating buildings comprised of 2.2 million square feet which were 99.6% occupied and an additional 181.4 acres of land available for development.
	IDI/DCT, LLC
	During 2007, we entered into a joint venture agreement with Industrial Developments International, Inc. (“IDI”), an unrelated third-party developer, to acquire approximately 113 acres of land to develop four distribution buildings comprising approximately 1.9 million square feet in the Savannah, GA, Nashville, TN, Chicago, IL, and Stockton, CA markets. DCT has the right of first offer to buy each of the projects and the buildings are operating.
	As noted above during 2014, we purchased our partner’s 50.0% interest in one building in Chicago, IL and the venture sold its building located in Savannah, GA to a third-party.  As a result of capitalized development costs, we had deferred expenses of $0.5 million that were recognized during 2014 upon the disposition of the venture’s property.
	IDI/DCT Buford, LLC
	During 2008, we entered into a joint venture agreement with IDI to form IDI/DCT Buford, LLC. This joint venture was funded for the purpose of developing distribution buildings on approximately 47 acres of land contributed to the joint venture by DCT.  IDI and DCT have joint control in all major decisions.

	Debt Payoffs, Refinancing and Issuance
	During February 2013, we entered into an amendment with our syndicated bank group whereby we extended and increased our existing $175.0 million senior unsecured term loan to $225.0 million for a period of five years, extended our existing $300.0 million senior unsecured line of credit for a period of four years and received a commitment for an additional $175.0 million senior unsecured term loan with a term of two years. We closed on the additional $175.0 million in March 2013, which was used to refinance a scheduled June 2013 maturity of $175.0 million of other senior unsecured debt.
	During March and April 2013, we retired $11.0 million mortgage notes previously scheduled to mature in April and June of 2013, using proceeds from the Company’s senior unsecured revolving credit facility and our equity offerings.
During June 2013, we issued two secured mortgage notes with principal balances of $1.0 million and $6.2 million which mature in June 2023. The notes bear interest at a variable rate; however we have fixed the rate at 4.72% using two interest rate swaps (See Note 6 – Financial Instruments and Hedging Activities for further detail). The notes require monthly payments of principal and interest.
During October 2013, the operating partnership issued $275.0 million aggregate principal amount of 4.50% senior notes due 2023 at 99.038% of face value in a private placement for net proceeds of approximately $269.6 million after offering costs. We primarily used the net proceeds to repay a $15.9 million mortgage note that was scheduled to mature in October 2013, a $50.0 million senior unsecured note that was scheduled to mature in January of 2014 and our $175.0 million senior unsecured term loan that was scheduled to mature in February 2015.
During January and November 2014, we retired $3.3 million and $43.3 million, respectively, mortgage notes previously scheduled to mature in April 2014 and January 2015, respectively, using proceeds from the Company’s senior unsecured revolving credit facility and our equity offerings.
Debt Assumptions
During the year ended December 31, 2014, we assumed three mortgage notes with aggregate outstanding balances totaling $18.3 million in connection with property acquisitions. We recorded approximately a $2.0 million premium in connection with the assumption of these notes.
For the years ended December 31, 2014, 2013 and 2012, the amortization of all premiums/discounts resulted in a reduction of interest expense of approximately $1.8 million, $2.1 million and $1.0 million, respectively, including amounts from discontinued operations.
Line of Credit
As of December 31, 2014, we had $37.0 million outstanding and $243.5 million available under our senior unsecured revolving credit facility, net of three letter of credits totaling $19.5 million. As of December 31, 2013, we had $39.0 million outstanding and $261.0 million available under our senior unsecured revolving credit facility.
Guarantee of Debt
DCT has guaranteed the Operating Partnership’s obligations with respect to the senior unsecured notes and the senior unsecured revolving credit.
Interest Expense and Capitalized Interest
During the years ended December 31, 2014, 2013 and 2012, we incurred interest expense of approximately $72.3 million, $71.7 million and $73.7 million, respectively, including amounts included in discontinued operations. We capitalized approximately $9.1 million, $8.3 million and $4.3 million of interest in 2014, 2013 and 2012, respectively, associated with certain development, redevelopment and other construction activities.

Fair Value Disclosures [Abstract]
Financial Instruments And Hedging Activities	Note 6 – Financial Instruments and Hedging Activities
	Fair Value of Financial Instruments
	As of December 31, 2014 and 2013, the fair values of cash and cash equivalents, restricted cash, accounts receivable and accounts payable approximated their carrying values due to the short-term nature of settlement of these instruments. The fair values of other financial instruments subject to fair value disclosures were determined based on available market information and valuation methodologies we believe to be appropriate estimates for these purposes. Considerable judgment and a high degree of subjectivity are involved in developing these estimates. Our estimates may differ from the actual amounts that we could realize upon disposition. The following table summarizes these financial instruments (in thousands):
		As of December 31, 2014						As of December 31, 2013
		Carrying			Estimated			Carrying			Estimated
		Amounts			Fair Value			Amounts			Fair Value
	Borrowings(1):

	Interest rate contracts:
	Interest rate swap asset (liability)(3)	$	(167	)	$	(167	)	$	212		$	212
	(1)	The fair values of our borrowings were estimated using a discounted cash flow methodology. Credit spreads and market interest rates used to determine the fair value of these instruments are based on unobservable Level 3 inputs which management has determined to be its best estimate of current market values.
	(2)	The carrying amount of our fixed rate debt includes premiums and discounts.
	(3)	The fair value of our interest rate swap is determined using the market standard methodology of netting the discounted future fixed cash flows and the discounted expected variable cash flows based on an expectation of future interest rates derived from Level 2 observable market interest rate curves. We also incorporate a credit valuation adjustment, which is derived using unobservable Level 3 inputs, to appropriately reflect both our nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurement. The asset or liability is included in “Other assets, net” or “Other liabilities,” respectively, in our Consolidated Balance Sheets.
	The following table displays a reconciliation of assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the years ended December 31, 2014 and 2013 (in thousands). The table also displays gains and losses due to changes in fair value, including both realized and unrealized, recognized in the Consolidated Statements of Operations for Level 3 liabilities. When assets and liabilities are transferred between levels, we recognize the transfer at the beginning of the period. There were no transfers between levels during the years ended December 31, 2014 and 2013.

	Realized loss recognized in interest expense		154			89
	Ending balance at December 31	$	(167	)	$	212
	Hedging Activities
	To manage interest rate risk for variable rate debt and issuances of fixed rate debt, we primarily use treasury locks and interest rate swaps as part of our cash flow hedging strategy. These derivatives are designed to mitigate the risk of future interest rate increases by providing a fixed interest rate for a limited, pre-determined period of time. Such derivatives have been used to hedge the variability in existing and future interest expense associated with existing variable rate borrowings and forecasted issuances of debt, which may include the issuances of new debt, as well as refinancing of existing debt upon maturity.
	Accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the designation of the derivative, 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. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. 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.
	For derivatives designated as “cash flow” hedges, the effective portion of the changes in the fair value of the derivative is initially reported in OCI in our Consolidated Statements of Comprehensive Income (Loss) (i.e., not included in earnings) and subsequently reclassified into earnings when the hedged transaction affects earnings or the hedging relationship is no longer effective at which time the ineffective portion of the derivative’s changes in fair value is recognized directly into earnings. We assess the effectiveness of each hedging relationship whenever financial statements are issued or earnings are reported and at least every three months. We do not use derivatives for trading or speculative purposes.
	During June 2013, certain of our consolidated ventures entered into two pay-fixed, receive-floating interest rate swaps to hedge the variability of future cash flows attributable to changes in the 1 month LIBOR rates. The pay-fixed, receive-floating swaps have an effective date of June 2013 and a maturity date of June 2023. These interest rates swaps effectively fix the interest rate on the related debt instruments at 4.72%. As of December 31, 2014 and 2013, we had borrowings payable subject to pay-fixed, received-floating interest swaps with aggregate principal balances of approximately $7.0 million and $7.1 million, respectively.
	The following table presents the effect of our derivative financial instruments on our accompanying consolidated financial statements for the years ended December 31, 2014, 2013 and 2012 (in thousands):
		Year Ended December 31,

	Amounts reported in “Accumulated other comprehensive loss” related to derivatives will be amortized to “Interest expense” as interest payments are made on our current debt and anticipated debt issuances. During the next 12 months, we estimate that approximately $4.2 million will be reclassified from “Accumulated other comprehensive loss” to “Interest expense” resulting in an increase in interest expense.

	On August 13, 2013, we issued 5.8 million shares of common stock in a public offering at a price of $28.80 per share for proceeds of approximately $158.2 million, net of offering expenses, used for acquisitions, development activities, repayment of amounts under our senior unsecured revolving credit facility and other general purposes.
	On September 12, 2012, we issued 4.8 million shares of common stock in a public offering at a price of $24.80 per share for proceeds of approximately $112.1 million, net of offering expenses, used for acquisition and other general purposes.
	During the years ended December 31, 2014, 2013 and 2012, we issued approximately 0.1 million, 0.1 million and 0.1 million, respectively, shares of common stock related to vested shares of restricted stock, phantom shares and stock option exercises.
	The holders of shares of our common stock are entitled to one vote per share on all matters voted on by stockholders, including election of our directors. Our articles of incorporation, as amended, do not provide for cumulative voting in the election of our directors. Therefore, the holders of the majority of the outstanding shares of common stock can elect the entire board of directors. Subject to any preferential rights of any outstanding series of our preferred stock and to the distribution of specified amounts upon liquidation with respect to shares-in-trust, the holders of our common stock are entitled to such distributions as may be declared from time to time by our board of directors out of legally available funds and, upon liquidation, are entitled to receive all assets available for distribution to stockholders. All shares issued in our public offerings are fully paid and non-assessable shares of common stock. Holders of our common stock will not have preemptive rights.
	Operating Partnership
	OP Units
	For each share of common stock issued by DCT, the Operating Partnership issues a corresponding OP Unit to DCT in exchange for the contribution of the proceeds from the stock issuances.
	As of December 31, 2014 and 2013, DCT owned approximately 95.4% and 94.8%, respectively, of the outstanding equity interests in the Operating Partnership. The remaining common partnership interests in the Operating Partnership were owned by executives of the Company and non-affiliated limited partners.
	Limited partners have the right to require the Company to redeem all or a portion of the OP Units held by the limited partner at a redemption price equal to and in the form of the Cash Amount (as defined in the Partnership Agreement), provided that such OP Units have been outstanding for at least one year. The Company may, in its sole discretion, purchase the OP Units by paying to the limited partner either the Cash Amount or the REIT Shares Amount (generally one share of DCT’s common stock for each OP Unit), as defined in the Partnership Agreement.
	During the years ended December 31, 2014, 2013 and 2012, approximately 0.4 million, 0.8 million and 1.6 million OP Units were redeemed for approximately $1.0 million, $1.5 million and $3.3 million in cash and approximately 0.3 million, 0.7 million and 1.4 million shares of DCT common stock, respectively.
	As of December 31, 2014, 2013 and 2012, there were approximately 4.2 million, 4.4 million and 5.0 million outstanding OP Units held by entities other than DCT and redeemable, with an aggregate redemption value of approximately $149.8 million, $125.9 million and $129.8 million based on the $35.66, $28.52 and $25.96 per share closing price of DCT’s common stock on December 31, 2014, 2013 and 2012, respectively.
	Allocations of Net Income and Net Losses to Partners
	The Operating Partnership’s net income and loss will generally be allocated to the general partner and the limited partners in accordance with the respective percentage interests in the OP Units issued by the Operating Partnership
	Dividend Reinvestment and Stock Purchase Plan
	We offer shares of common stock through the Dividend Reinvestment and Stock Purchase Plan (the “Plan”). The Plan permits stockholders to acquire additional shares with quarterly dividends and to make additional cash investments to buy shares directly. Shares of common stock may be purchased in the open market, through privately negotiated transactions, or directly from us as newly issued shares of common stock. All shares issued under the Plan were either acquired in the open market or newly issued.
	Preferred Shares
	Our board of directors, through the articles of incorporation, as amended, has the authority to authorize the issuance of 50,000,000 preferred shares of any class or series. The rights and terms of such preferred shares will be determined by our board of directors. However, the voting rights of preferred stockholders shall never exceed the voting rights of common stockholders. As of December 31, 2014 and 2013, we had no outstanding shares of preferred stock.
	Shares-in-Trust
	Our board of directors, through the articles of incorporation, as amended, has the authority to authorize the issuance of 100,000,000 shares-in-trust which are shares that are automatically exchanged for common or preferred shares as a result of an event that would cause an investor to own, beneficially or constructively, a number of shares in excess of certain limitations. As of December 31, 2014 and 2013, we had no outstanding shares-in-trust.
	Distributions
	Our distributions are calculated based upon the total number of shares of our common stock and OP Units outstanding on the distribution record date as declared by our board of directors. We accrue and pay distributions on a quarterly basis. The following table sets forth the distributions that have been paid and/or declared to date by our board of directors:

Earnings Per Share [Abstract]
Earnings Per Share
	Note 10 – Earnings per Share
	We use the two-class method of computing earnings per common share/unit which is an earnings allocation formula that determines earnings per share/unit for common stock/unit and any participating securities according to dividends declared (whether paid or unpaid) and participation rights in undistributed earnings. Under the two-class method, earnings per common share/unit are computed by dividing the sum of distributed earnings to common stockholders/OP Unitholders and undistributed earnings allocated to common stockholders/OP Unitholders by the weighted average number of common shares/units outstanding for the period.
	A participating security is defined by GAAP as an unvested share-based payment award containing non-forfeitable rights to dividends and must be included in the computation of earnings per share/unit pursuant to the two-class method. Nonvested restricted stock and LTIP Units are considered participating securities as these share-based awards contain non-forfeitable rights to dividends irrespective of whether the awards ultimately vest or expire.

We have excluded from diluted earnings per share the weighted average common share equivalents or common unit equivalents related to 0.7 million and 0.8 million stock options and phantom stock for the years ended December 31, 2013 and 2012, respectively, because their effect would be anti-dilutive.
Additionally, for the years ended December 31, 2014, 2013 and 2012, DCT excluded from diluted earnings per share the weighted average common share equivalents related to 4.3 million, 4.8 million and 5.8 million OP Units, respectively, because their effect would be anti-dilutive.

Equity_Based_Compensation

Equity Based Compensation	12 Months Ended
	Dec. 31, 2014
Share Based Compensation [Abstract]
Equity Based Compensation	Note 11 – Equity Based Compensation
	Long-Term Incentive Plan
	On October 10, 2006, the Company established the Long-Term Incentive Plan, as amended, to grant restricted stock, stock options and other awards to our personnel and directors, as defined in the plan. Subject to adjustment upon certain corporate transactions or events, the total number of shares of our common stock subject to such awards may not exceed 5.8 million shares and in no event may any optionee receive options for more than 0.5 million shares on an annual basis.
	Phantom Shares
	Pursuant to the Long-Term Incentive Plan, as amended, the Company may grant phantom shares to non-employee directors. Phantom shares generally vest upon the first anniversary of the grant date, depending on the grant. Once vested and at the discretion of the grantee, the phantom stock can be converted into either cash or common stock at the option of the Company. Phantom shares are recorded at their fair value on the date of grant and are amortized on a straight-line basis over the service period during which term the shares fully vest.
	Restricted Stock
	Restricted stock is recorded at fair value on the date of grant and amortized on a straight-line basis over the service period during which term the stock fully vests. Restricted stock generally vests ratably over a period of four to five years, depending on the grant.
	LTIP Units
	Pursuant to the Long-Term Incentive Plan, as amended, the Company may grant limited partnership interests in the Operating Partnership called LTIP Units. Vested LTIP Units may be redeemed by the Company in cash or DCT common stock, at the discretion of the Company, on a one-for-one basis with common shares, subject to certain restrictions of the Partnership Agreement. LTIP Units receive distributions equally along with common shares. LTIP Units are valued by reference to the value of DCT’s common stock and generally vest ratably over a period of four to five years, depending on the grant. LTIP Unit equity compensation is amortized into expense over the service period during which the units vest.
	During the year ended December 31, 2014, approximately 0.2 million LTIP Units were granted to certain senior executives, which vest over a four to five year period with a total fair value of $4.3 million at the date of grant as determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation using a weighted average volatility factor of 40% and a weighted average risk-free interest rate of 1.47%.
	During the year ended December 31, 2013, 0.2 million LTIP Units were granted to senior executives, which vest over a four year period with a total fair value of $4.6 million at the date of grant as determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation using a volatility factor of 52% and risk-free interest rate of 0.84%.
	During the year ended December 31, 2012, we granted approximately 0.2 million LTIP Units to senior executives, which vest over a period of four to five years with a total fair value $3.9 million at the date of grant as determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation using a volatility factor of 72% and risk-free interest rates ranging from 0.82% to 1.04%.
	Multi-Year Outperformance Program
	On January 11, 2011, the Company adopted a multi-year outperformance program, which is a long-term incentive compensation program, and granted awards under the program to certain officers and senior executives.
	The awards entitle participants to receive shares of DCT’s common stock with a maximum value of $10 million based on the absolute and relative total return to stockholders during the three-year performance period beginning on December 31, 2009. Half of the awards are based on DCT’s absolute total return to stockholders during the performance period and the other half are based on our relative total return to stockholders during the performance period compared to the performance of the MSCI US REIT Index during the same period.
	Each participant’s award is designated as a specified percentage of the aggregate award value earned during the performance period, and participants are also entitled to a share of any unallocated portion of the aggregate award value. At the end of the performance period, each participant will be issued shares of DCT’s common stock with a value equal to that participant’s share of the aggregate award value. Half of the shares of common stock issued will be fully vested upon issuance at the end of the performance period and the remaining half will vest on the first anniversary of that date based on continued employment. The Company may also permit participants to elect to receive their awards in the form of LTIP Units or other equivalent forms of equity in lieu of shares of DCT’s common stock.
	During the year ended December 31, 2013, approximately 0.1 million LTIP Units were granted with a grant date fair value of approximately $2.4 million. We did not grant any awards under the program during 2014.
	The following table summarizes the number of awards redeemed and converted to DCT’s common stock on a one for one basis, the fair value at grant date for the awards vested during the period and the number of awards outstanding at period end related to phantom shares, restricted stock and LTIP Units:

The term of such options is 10 years from the date of grant unless forfeited earlier and the period during which the right to exercise such options fully vests ranges from four to five years from the date of grant. No stock options were granted under our Long-Term Incentive Plan, as amended, prior to 2007. During the year ended December 31, 2014, we issued approximately 56,000 shares of common stock upon the exercise of options to purchase DCT’s common stock by certain employees. There were no options granted during the years ended December 31, 2014, 2013 and 2012.
	Independent Director Option Plan
	Prior to October 6, 2006, we granted stock options under the Independent Director Option Plan, which we used in an effort to attract and retain qualified independent directors. No options were issued under this plan subsequent to 2006.

	8th and Vineyard Consolidated Joint Venture
	In May 2010 we entered into the 8th and Vineyard joint venture with Iowa Investments, LLC, an entity owned by one of our executives, to purchase 19.3 acres of land held for development in Southern California. Pursuant to the joint venture agreement, we will first receive a return of all capital along with a preferred return. Thereafter, Iowa Investments, LLC will receive a return of all capital along with a promoted interest. The land parcel acquired by 8th and Vineyard was purchased from an entity in which the same executive had a minority ownership. The total acquisition price of $4.7 million was determined to be at fair value.
	During 2014, we completed the construction and disposition of two buildings. See “Note 3 – Investment in Properties” for additional information
	Southern California Consolidated Ventures
	We entered into four agreements, two in December 2010 and two in January 2011, whereby we acquired a weighted average ownership interest, based on square feet, of approximately 48.4% in five bulk industrial buildings located in the Southern California market. Entities controlled by one of our executives have a weighted average ownership in these properties of approximately 43.7%, based on square feet, and the remaining 7.9% is held by a third-party. Each venture partner will earn returns in accordance with their ownership interests. We have controlling rights including management of the operations of the properties and we have consolidated the properties in accordance with GAAP. The total acquisition price of $46.3 million was determined to be at fair value.

	We operate and expect to continue to operate in a manner to meet all the requirements to qualify for REIT status. We have made our REIT election under Section 856 of the Code for the taxable year ended December 31, 2003 and have not revoked such election. In order for a former C corporation to elect to be a REIT, it must distribute 100% of its C corporation earnings and profits and agree to be subject to federal tax at the corporate level to the extent of any subsequently recognized built-in gains within a 10 year period. We did not have any built-in gains at the time of our conversion to REIT status. As a REIT, we generally will not be subject to federal income taxation at the corporate level to the extent we annually distribute 100% of our REIT taxable income, as defined under the Code, to our stockholders and satisfy other requirements. To continue to qualify as a REIT for federal tax purposes, we must distribute at least 90% of our REIT taxable income annually.

	Deferred Income Taxes
	Deferred income taxes represent the tax effect of temporary differences between the book and tax basis of assets and liabilities. As of December 31, 2014, we had recorded a $2.2 million deferred tax asset, net of valuation allowance of $1.7 million, included in the Consolidated Balance Sheets in “Other assets, net”, and a $0.9 million deferred tax liability, included in the Consolidated Balance Sheets in “Other liabilities”, for federal and state income taxes on our taxable REIT subsidiaries. For the year ended December 31, 2014, net deferred taxes decreased by $0.1 million.  $1.1 million of income tax benefit is included in “Income tax benefit (expense) and other taxes” and $1.2 million of tax expense is included in “Development profit, net of taxes” in our Consolidated Statements of Operations.  As of December 31, 2013, we had recorded a $2.3 million deferred tax asset, net of valuation allowance of $2.3 million, and a $0.8 million deferred tax liability for federal and state income taxes on our taxable REIT subsidiaries.

Segment Reporting [Abstract]
Segment Information	Note 14 – Segment Information
	The Company’s segments are based on our internal reporting of operating results used to assess performance based on our properties’ geographical markets. Our markets are aggregated into three reportable regions or segments, East, Central and West, which are based on the geographical locations of our properties. Management considers rental revenues and property net operating income aggregated by segment to be the appropriate way to analyze performance. The following segment disclosures exclude the results from discontinued operations (see “Note 15 – Discontinued Operations and Assets Held for Sale” for additional information).
	The following table reflects our total assets, net of accumulated depreciation and amortization, by segment, as of December 31, 2014 and 2013 (in thousands):

	Income (loss) from continuing operations	$	46,531		$	(9,251	)	$	(28,540	)
	(1)	Property net operating income (“property NOI”) is defined as rental revenues, including reimbursements, less rental expenses and real estate taxes, which excludes institutional capital management fees, depreciation, amortization, casualty and involuntary conversion gains, impairment, general and administrative expenses, equity in earnings (loss) of unconsolidated joint ventures, interest expense, interest and other income (expense) and income tax benefit (expense) and other taxes. We consider property NOI to be an appropriate supplemental performance measure because property NOI reflects the operating performance of our properties and excludes certain items that are not considered to be controllable in connection with the management of the property such as depreciation, amortization, impairment, general and administrative expenses and interest expense. However, property NOI should not be viewed as an alternative measure of our financial performance since it excludes expenses which could materially impact our results of operations. Further, our property NOI may not be comparable to that of other real estate companies, as they may use different methodologies for calculating property NOI. Therefore, we believe net income (loss) attributable to common stockholders, as defined by GAAP, to be the most appropriate measure to evaluate our overall financial performance.

Discontinued Operations And Assets Held For Sale
	Note 15 – Discontinued Operations and Assets Held for Sale
	Assets Held for Sale
	As of December 31, 2014, there were no properties classified as held for sale.
	Discontinued Operations
	We report results of operations from real estate assets that meet the definition of a component of an entity, have been sold or meet the criteria to be classified as held for sale, for which the disposal or expected disposal represents a strategic shift in operations, as discontinued operations. Real estate assets that meet the definition of a component of an entity and were disposed of or held for sale prior to January 1, 2014 are reported as discontinued operations. See “Note 2 – Summary of Significant Accounting Policies” for additional information regarding discontinued operations and our January 1, 2014 adoption of ASU 2014-08.
	As of December 31, 2013, we had one operating property in our Central operating segment classified as held for sale that was subsequently sold in May 2014 and reported as a discontinued operation for the year ended December 31, 2014.
	During the year ended December 31, 2014, we sold 37 consolidated operating properties to unrelated third-parties. Twelve of these properties were in the East operating segment and 25 were in the Central operating segment, together totaling approximately 6.4 million square feet.  We recognized gains of approximately $43.9 million on the disposition of 33 properties and recognized impairment losses of approximately $5.4 million on the disposition of 4 properties. The estimated fair values of the impaired properties were based upon the contractual sales price, a Level 2 fair value measurement.
	During the year ended December 31, 2013, we sold 51 consolidated operating properties to unrelated third-parties. Three of these properties were in the East operating segment, 47 were in the Central operating segment and one was in the West operating segment, together totaling approximately 6.8 million square feet.  We recognized gains of approximately $33.6 million on the disposition of 36 properties and recognized impairment losses of approximately $13.3 million on the disposition of a portfolio of 15 properties in Dallas. The estimated fair values of the impaired properties were based upon the contractual sales price, a Level 2 fair value measurement.
	During the year ended December 31, 2012, we sold 36 operating properties to unrelated third-parties. Sixteen of these properties were in the Central operating segment and 20 were in the East operating segment, together totaling approximately 4.1 million square feet. These sales resulted in gains of approximately $13.4 million and impairment losses totaling approximately $11.4 million. The impairment losses were recorded on a portfolio of 13 properties in Atlanta as the assets’ carrying value exceeded their estimated fair value less costs to sell. The estimated fair value of these properties was based upon the contractual sales price, a Level 2 fair value measurement.
	The following is a summary of the components of income from discontinued operations for the years ended December 31, 2014, 2013 and 2012 (in thousands):

Condensed Financial Information Of Parent Company Only Disclosure [Abstract]
Condensed Consolidated Financial Information	Note 17 – Condensed Consolidated Financial Information
	During October 2013, the Operating Partnership issued $275.0 million aggregate principal amount of 4.50% senior notes at 99.038% of face value in a private placement. The senior notes are jointly and severally, fully and unconditionally guaranteed by DCT and certain of the Company’s wholly owned subsidiaries. During May 2014, we completed the exchange of these notes for SEC registered notes having substantially identical terms.
	The following tables present the condensed consolidated financial information for (a) DCT Industrial Trust, Inc. (“Parent” and a guarantor), (b) DCT Industrial Operating Partnership LP (“Subsidiary Issuer”), (c) on a combined basis, the guarantor subsidiaries (“Subsidiary Guarantors”), and (d) on a combined basis, the non-guarantor subsidiaries (“Non-Guarantor Subsidiaries”). Additional columns present consolidating adjustments and consolidated totals as of December 31, 2014 and 2013 and for years ended December 31, 2014, 2013 and 2012.
	As the guarantees were made in connection with our note offering in October 2013, the Subsidiary Guarantors’ condensed consolidated information as of December 31, 2013 and 2012 is presented based on the guarantors as of December 31, 2013. Subsequent to December 31, 2013, certain of our subsidiaries were released from their guarantees, primarily due to the disposition of properties. These changes in guarantors were reflected prospectively.
	Separate financial statements of the Subsidiary Guarantors are not presented because the guarantee by each 100% owned Subsidiary Guarantor is full and unconditional, joint and several. Furthermore, there are no significant legal restrictions on the Parent’s ability to obtain funds from its subsidiaries by dividend or loan.
	Investments in consolidated subsidiaries are accounted for using the equity method for purposes of the combined presentation. The consolidated adjustments principally relate to the elimination of investments in consolidated subsidiaries and intercompany balances and transactions.

Subsequent Events [Abstract]
Subsequent Events	Note 18 – Subsequent Events
	GAAP requires an entity to disclose events that occur after the balance sheet date but before financial statements are issued or are available to be issued (“subsequent events”) as well as the date through which an entity has evaluated subsequent events. There are two types of subsequent events. The first type consists of events or transactions that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements, (“recognized subsequent events”). The second type consists of events that provide evidence about conditions that did not exist at the date of the balance sheet but arose subsequent to that date (“nonrecognized subsequent events”). No significant recognized or nonrecognized subsequent events were noted.

Summary Of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Basis Of Presentation	Basis of Presentation and Principles of Consolidation
	The accompanying Consolidated Financial Statements include the financial position, results of operations and cash flows of the Company, the Operating Partnership, their wholly-owned qualified REIT subsidiaries and taxable REIT subsidiaries, and their consolidated joint ventures, in which they have a controlling interest.
	Equity interests in the Operating Partnership held by entities other than DCT are classified within partners’ capital in the Operating Partnership’s financial statements and as noncontrolling interests in DCT’s financial statements. Equity interests in entities consolidated into the Operating Partnership that are held by third parties are reflected in our accompanying balance sheets as noncontrolling interests in consolidated entities. We also have noncontrolling partnership interests in unconsolidated institutional capital management and other joint ventures, which are accounted for under the equity method. All significant intercompany transactions and balances have been eliminated in consolidation.
	All square feet, acres, occupancy, number of properties, number of customers and total projected investment disclosed in the notes to the Consolidated Financial Statements are unaudited.
Principles Of Consolidation	We hold interests in both consolidated and unconsolidated joint ventures. All joint ventures over which we have financial and operating control, and variable interest entities (“VIEs”) in which we have determined that we are the primary beneficiary, are included in the Consolidated Financial Statements. We use the equity method of accounting for joint ventures over which we do not have a controlling interest or where we do not exercise significant control over major operating and management decisions but where we exercise significant influence and include our share of earnings or losses of these joint ventures in our consolidated results of operations.
	We analyze our joint ventures in accordance with generally accepted accounting principles (“GAAP”) to determine whether they are VIEs and, if so, whether we are the primary beneficiary. Our judgment with respect to our level of influence or control over an entity and whether we are the primary beneficiary of a VIE involves consideration of various factors including the form of our ownership interest, our representation on the entity’s board of directors, the size of our investment (including loans) and our ability to participate in major decisions. Our ability to correctly assess our influence or control over an entity affects the presentation of these investments in the Consolidated Financial Statements and, consequently, our financial position and results of operations.
Use Of Estimates	Use of Estimates
	The preparation of the Consolidated Financial Statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Capitalization Of Costs	Capitalization of Costs
	We capitalize costs directly related to the development, pre-development, redevelopment or improvement of our investment in real estate, referred to as capital projects and other activities included within this paragraph. Costs associated with our capital projects are capitalized as incurred. If the project is abandoned, these costs are expensed during the period in which the project is abandoned. Costs considered for capitalization include, but are not limited to, construction costs, interest, real estate taxes and insurance, if appropriate. We capitalize indirect costs such as personnel, office and administrative expenses that are directly related to our development projects based on an estimate of the time spent on the construction and development activities. These costs are capitalized only during the period in which activities necessary to ready an asset for its intended use are in progress and such costs are incremental and identifiable to a specific activity to get the asset ready for its intended use. We determine when the capitalization period begins and ends through communication with project and other managers responsible for the tracking and oversight of individual projects. In the event that the activities to ready the asset for its intended use are suspended, the capitalization period will cease until such activities are resumed. In addition, we capitalize initial direct costs incurred for successful origination of new leases. Costs incurred for maintaining and repairing our properties, which do not extend their useful lives, are expensed as incurred.
	Interest is capitalized based on actual capital expenditures from the period when development or redevelopment commences until the asset is ready for its intended use, at the weighted average borrowing rate during the period. We also capitalize interest on our qualifying investments in unconsolidated joint ventures based on the average capital invested in a venture during the period when the venture has activities in progress necessary to commence its planned principal operations, at our weighted average borrowing rate during the period. A “qualifying investment” is an investment in an unconsolidated joint venture provided that our investee’s activities include the use of funds to acquire qualifying assets, such as development or predevelopment activities, and planned principal operations have not commenced.
Discontinued Operations and Assets Held for Sale	Discontinued Operations and Assets Held for Sale
	We classify certain properties and related assets and liabilities as held for sale when certain criteria are met. At such time, the respective assets and liabilities are presented separately on our Consolidated Balance Sheets. We include liabilities related to assets held for sale that will be transferred in the transaction in “Liabilities related to assets held for sale.” Assets held for sale are reported at the lower of carrying value or estimated fair value less estimated costs to sell.
	Effective January 1, 2014, we adopted accounting standard update (“ASU”) No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, for all properties not previously sold or classified as held for sale.  ASU 2014-08 revised the reporting requirements to only allow a component of an entity, or group of components of an entity, to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results.  Prior to January 1, 2014, properties identified as held for sale and/or disposed of are presented in discontinued operations for all periods presented.
	Gains on sales of real estate assets are recognized if the specific transaction terms meet the various sale recognition criteria as defined by GAAP. If the criteria are not met, we defer the gain until such time that the criteria for sale recognition have been met. Net gains on sales and any impairment losses associated with assets held for sale are presented in continuing operations when recognized.
Fair Value	Fair Value
	GAAP establishes a framework for measuring fair value and requires disclosures about fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants. The guidance establishes a hierarchy for inputs used in measuring fair value based on observable and unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are based on market data obtained from sources independent of DCT. Unobservable inputs are inputs that reflect our assumptions of pricing the asset or liability based on the best information available in the circumstances. The hierarchy is broken down into three levels as follows:
	Level 1: Inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets;
	Level 2: Inputs include quoted prices for similar assets and liabilities in active or inactive markets or that are observable either directly or indirectly for the asset or liability; and
	Level 3: Unobservable inputs are typically based on management’s own assumptions, as there is little, if any, related observable market activity.
	DCT’s assets and liabilities that are measured at fair value are classified in their entirety based on the lowest level of input that is significant to their fair value measurement. Our 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.
Investment In Properties	Investment in Properties
	We record the assets, liabilities and noncontrolling interests associated with property acquisitions which qualify as business combinations at their respective acquisition date fair values which are derived using a market, income or replacement cost approach, or combination thereof. Acquisition related costs associated with business combinations are expensed as incurred. As defined by GAAP, a business is an integrated set of activities and assets that is capable of being conducted and managed for the purpose of providing a return in the form of dividends, lower costs or other economic benefits directly to investors or other owners, members or participants. We do not consider acquisitions of land or unoccupied buildings to be business combinations. Rather, these transactions are treated as asset acquisitions and recorded at cost.
	The fair value of identifiable tangible assets such as land, building, building and land improvements, and tenant improvements is determined on an “as-if-vacant” basis. Management considers Level 3 inputs such as the replacement cost of such assets, appraisals, property condition reports, market data and other related information in determining the fair value of the tangible assets. 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 the current market rate for similar liabilities. The recorded fair value of intangible lease assets includes Level 3 inputs and represents the value associated with in-place leases which include leasing commissions, legal and other costs, as well as an intangible asset or liability resulting from in-place leases being above or below the market rental rates over the lease term on the date of the acquisition. Intangible lease assets or liabilities are amortized over the reasonably assured lease term of the remaining in-place leases as an adjustment to “Rental revenues” or “Real estate related depreciation and amortization” depending on the nature of the intangible.
	We have certain properties which we have acquired or removed from service with the intention to redevelop the property. Buildings under redevelopment require significant construction activities prior to being placed back into service. We generally do not depreciate properties classified as redevelopment until the date that the redevelopment properties are ready for their intended use.
	Real estate, including land, building, building and land improvements, tenant improvements, 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 its estimated fair value.
Depreciation And Useful Lives Of Properties
	Depreciation and Useful Lives of Real Estate Assets
	Depreciation and amortization are computed on a straight-line basis over the estimated useful lives of the related assets or liabilities. Our ability to assess the useful lives of our real estate assets accurately is critical to the determination of the appropriate amount of depreciation and amortization expense recorded and the carrying values of the underlying assets. Any change to the estimated depreciable lives of these assets would have an impact on the depreciation and amortization expense we recognize.
	The following table reflects the standard depreciable lives generally used to compute depreciation and amortization. However, such depreciable lives may be different based on the estimated useful life of such assets or liabilities. The carrying value of assets sold or retired and the related accumulated depreciation and/or amortization is derecognized and the resulting gain or loss, if any, is recorded during the period in which such sale or retirement occurs.
	Description	Expected Useful Life
	Land	Not depreciated
	Building	20 – 40 years
	Building and land improvements	5 – 20 years
	Tenant improvements	Shorter of lease term or useful life
	Leasing costs	Lease term
	Other intangible lease assets	Average term of leases for property
	Above/below market rent assets/liabilities	Reasonably assured lease term
	Depreciation is not recorded on real estate assets currently held for sale, in pre-development, or being developed or redeveloped until the building is substantially completed and ready for its intended use, not later than one year from cessation of major construction activity.
Impairment Of Properties	Impairment of Properties
	Investments in properties classified as held for use are carried at cost and evaluated for impairment at least annually and whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be recoverable. Examples of such changes in circumstances include the point at which we deem a building to be held for sale, our intended hold period changes, or when a building remains vacant significantly longer than expected. For investments in properties that we intend to hold long-term, the recoverability is based on estimated future undiscounted cash flows. If the asset carrying value is not supported on an undiscounted cash flow basis, the amount of impairment is measured as the difference between the carrying value and the fair value of the asset and is reflected in “Impairment losses” on the Consolidated Statements of Operations. The determination of fair value of real estate assets to be held for use is derived using the discounted cash flow method and involves a number of management assumptions relating to future economic events that could materially affect the determination of the ultimate value, and therefore, the carrying amounts of our real estate. Such assumptions are Level 3 inputs and include, but are not limited to, projected vacancy rates, rental rates, property operating expenses and capital expenditures. The capitalization rate is also a significant driving factor in determining the property valuation and requires management’s judgment of factors such as market knowledge, historical experience, lease terms, customer financial strength, economy, demographics, environment, property location, visibility, age, physical condition and expected return requirements, among other things. The aforementioned factors are taken as a whole by management in determining the valuation of investment property. The valuation is sensitive to the actual results of any of these uncertain factors, either individually or taken as a whole. Should the actual results differ from management’s estimates, the valuation could be negatively affected and may result in additional impairment losses recorded in the Consolidated Financial Statements.
Investments In And Advances To Unconsolidated Joint Venture	Investments in and Advances to Unconsolidated Joint Ventures
	We account for our investments in and advances to unconsolidated joint ventures under the equity method because we exercise significant influence over, but do not control, these entities. Under the equity method, these investments (including advances to joint ventures) are initially recorded at cost and are subsequently adjusted to reflect our proportionate share of net earnings or losses of each of the joint ventures, distributions received, contributions made and certain other adjustments, as appropriate. Such investments are included in “Investments in and advances to unconsolidated joint ventures” in our Consolidated Balance Sheets. Distributions from these investments that are related to cash earnings from operations are included as operating activities and distributions that are related to capital transactions are included as investing activities in our Consolidated Statements of Cash Flows.
	Investment properties that were contributed to unconsolidated joint ventures prior to the adoption of ASU 2014-08 are not considered discontinued operations due to our continuing involvement through maintaining an ownership interest in these investment properties and continuing to act as manager of the assets. We recognize any gains from the contribution of investment properties into an unconsolidated joint venture if the recognition criteria have been met and the cash received is not required to be reinvested. Such gains are recognized to the extent of the outside ownership interest in the joint venture in our Consolidated Statements of Operations under the heading of “Gain on dispositions of real estate interests.” Any gain related to the remaining proceeds reduces our basis in the investment in the unconsolidated joint venture, and is recognized into earnings over the weighted average life of the related property’s real estate assets. We recognize our proportionate share of the ongoing earnings or losses of each unconsolidated joint venture in “Equity in earnings of unconsolidated joint ventures, net” in our Consolidated Statements of Operations.
Impairment of Investments in and Advances to Unconsolidated Joint Ventures	Impairment of Investments in and Advances to Unconsolidated Joint Ventures
	We evaluate our investments in unconsolidated entities for impairment whenever events or changes in circumstances indicate that there may be an other-than-temporary decline in value. To do so, we calculate the estimated fair value of the investment using a market, income or replacement cost approach, or combination thereof. The amount of impairment recognized, if any, would be the excess of the investment’s carrying amount over its estimated fair value. We consider various factors to determine if a decline in the value of the investment is other-than-temporary. These factors are Level 2 and 3 inputs and include but are not limited to, age of the venture, our intent and ability to retain our investment in the entity, the financial condition and long-term prospects of the entity, expected term of the investment and the relationships with the other joint venture partners and its lenders. If we believe that the decline in the fair value is temporary, no impairment is recorded. The aforementioned factors are taken as a whole by management in determining the valuation of our investment. Should the actual results differ from management’s estimates, the valuation could be negatively affected and may result in a negative impact on the Consolidated Financial Statements. See Note 4—Investments in and Advances to Unconsolidated Joint Ventures for additional information.
Cash And Cash Equivalents	Cash and Cash Equivalents
	Cash and cash equivalents include cash held in financial institutions and other highly liquid short-term investments with original maturities of three months or less. We have not realized any losses in our cash and cash equivalents and believe that these short-term instruments are not exposed to any significant credit risk.
Restricted Cash	Restricted Cash
	Restricted cash consists of escrow deposits held by lenders for real estate taxes, insurance and capital replacement reserves, security deposits and amounts held by intermediary agents to be used for tax-deferred, like-kind exchange transactions.  For the year ended December 31, 2013, approximately $8.8 million of restricted cash was included in “Investing Activities” in our Consolidated Statements of Cash Flows related to tax deferred, like-kind exchange transactions.  For the year ended December 31, 2014, all funds had been utilized in tax deferred, like-kind exchange transactions.
Deferred Loan Costs	Deferred Loan Costs
	Deferred loan costs include fees and costs incurred to obtain long-term financing. These fees and costs are amortized to “Interest expense” over the terms of the related loans. Accumulated amortization of deferred loan costs was approximately $8.5 million and $6.3 million as of December 31, 2014 and 2013, respectively. Unamortized deferred loan costs are fully amortized when debt is retired before the maturity. Our interest expense for the years ended December 31, 2014, 2013 and 2012 includes approximately $2.2 million, $2.7 million and $2.1 million for the amortization of loan costs, respectively, including amounts related to discontinued operations.
Straight-Line Rent And Other Receivables	Straight-line Rent and Other Receivables
	Straight-line rent and other receivables include all straight-line rent and current accounts receivable, net of allowances. We maintain an allowance for estimated losses that may result from the inability of our customers to make required payments. If a customer fails to make contractual payments beyond any allowance, we may recognize additional bad debt expense in future periods equal to the net outstanding balances. As of December 31, 2014 and 2013, our allowance for doubtful accounts was approximately $1.0 million and $2.2 million, respectively.
Debt
	Debt
	Debt consists of fixed and variable rate secured mortgage notes, senior unsecured notes and bank unsecured credit facilities. Discounts and premiums to the principal amounts are included in the carrying value of debt and amortized to “Interest expense” over the remaining life of the underlying debt. The aggregated premium balance, net of accumulated amortization, was approximately $2.6 million as of December 31, 2014 and 2013.
Derivative Instruments And Hedging Activities	Derivative Instruments and Hedging Activities
	We may use interest rate swaps to manage certain interest rate risk. We record derivatives at fair value which are presented on a gross basis in “Other assets, net” or “Other liabilities” in our Consolidated Balance Sheets. 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. 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 curves. 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 us and our counterparties.
	For derivatives designated as “cash flow” hedges, the effective portion of the changes in the fair value of the derivative is initially reported in “Accumulated other comprehensive loss” in our Consolidated Balance Sheets (i.e., not included in earnings) and subsequently reclassified into earnings when the hedged transaction affects earnings or the hedging relationship is no longer effective at which time the ineffective portion of the derivative’s change in fair value is recognized directly into earnings. We assess the effectiveness of each hedging relationship whenever financial statements are issued or earnings are reported and at least every three months. We do not use derivatives for trading or speculative purposes.
Comprehensive Income (Loss)	Comprehensive Income (Loss)
	We report comprehensive income (loss) in our Consolidated Statements of Comprehensive Income (Loss). Amounts reported in “Accumulated other comprehensive loss” related to settled hedging transactions will be amortized to “Interest expense” as the hedged forecasted transactions occur. Any ineffectiveness related to our hedging transactions is reported in our Consolidated Statements of Operations. See Note 6 – Financial Instruments and Hedging Activities for additional information.
Revenue Recognition	Revenue Recognition
	We record rental revenues on a straight-line basis under which contractual rent increases are recognized evenly over the lease term. Certain properties have leases that provide for tenant occupancy during periods where no rent is due or where minimum rent payments change during the term of the lease. Accordingly, we record receivables from tenants that we expect to collect over the remaining lease term rather than currently, which are recorded as a straight-line rent receivable. When we acquire a property, the terms of existing leases are considered to commence as of the acquisition date for the purposes of this calculation. The total increase to “Rental revenues” due to straight-line rent adjustments was approximately $9.9 million, $5.3 million and $6.3 million, respectively, for the years ended December 31, 2014, 2013 and 2012.
	Tenant recovery income includes payments and amounts due from tenants pursuant to their leases for real estate taxes, insurance and other recoverable property operating expenses and is recognized as “Rental revenues” during the same period the related expenses are incurred. Tenant recovery income recognized as “Rental revenues” was approximately $76.5 million, $63.8 million and $51.7 million, respectively, for the years ended December 31, 2014, 2013 and 2012.
	In connection with property acquisitions qualifying as business combinations, 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 Statements of Operations on a straight-line basis over the estimated remaining contractual lease term. The total net impact to “Rental revenues” due to the amortization of above and below market rents was an increase of approximately $2.4 million, $1.6 million and $0.8 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	Future minimum base rental payment, i.e., cash received for monthly contractual rent, due to us from our customers under the terms of non-cancelable operating leases that have commenced as of December 31, 2014 were as follows (in thousands):
	Year Ended December 31,	Amounts
	2015	$	248,914
	2016		221,669
	2017		183,342
	2018		143,447
	2019		112,324
	Thereafter		299,406
	Total	$	1,209,102
	The schedule does not reflect future rental revenues from the potential renewal or replacement of existing and future leases and excludes tenant recovery income. Additionally, leases where the tenant can terminate the lease with short-term notice are not included.
	Early lease termination fees are recorded in “Rental revenues” on a straight-line basis over the estimated remaining contractual lease term or upon collection if collectability is not assured. During the years ended December 31, 2014, 2013 and 2012, early lease termination fees were $2.1 million, $1.3 million and $0.6 million, respectively.
	We earn revenues from asset management fees, acquisition fees, property management fees and fees for other services pursuant to joint venture and other agreements. These are included in our Consolidated Statements of Operations in “Institutional capital management and other fees.” We recognize revenues from asset management fees, acquisition fees, property management fees and fees for other services when the related fees are earned and are realized or realizable.
	We develop certain properties for specific buyers, called build-to-suit projects. We make certain judgments based on the specific terms of each project as to the amount and timing of recognition of profits from the project. Projects are generally accounted for using the percentage of completion method or full accrual method. Profits under the percentage of completion method are based on our estimates of the percentage of completion of individual contracts, commencing when the work performed under the contracts reaches a point where the final costs can be estimated with reasonable accuracy. The percentage of completion estimates are based on a comparison of the contract expenditures incurred to the estimated final costs. Changes in job performance, job conditions and estimated profitability may result in revisions to the costs and income and are recognized in the period in which the revisions are determined. If the sale recognition criteria for using the percentage of completion or full accrual methods are not met, we apply another recognition method provided by GAAP, such as the installment or cost recovery methods. The profit recognized from these projects is reported net of estimated taxes, when applicable, and is included in “Development profit, net of taxes” in our Consolidated Statements of Operations.
Stock-Based Compensation	Stock-Based Compensation
	On October 10, 2006, we established the Long-Term Incentive Plan, as amended, to grant restricted stock, LTIP Units, stock options and other awards to our personnel and directors. Awards granted under this plan are measured at fair value on the grant date and amortized to compensation expense on a straight-line basis over the service period during which the awards fully vest. Such expense is included in “General and administrative” expense in our Consolidated Statements of Operations. Options issued under the Long-Term Incentive Plan are valued using the Black-Scholes option pricing model, which relies on assumptions we make related to the expected term of the options, volatility, dividend yield and risk-free interest rate.
Income And Other Taxes	Income and Other Taxes
	We have elected to be taxed as a REIT, as defined under the Internal Revenue Code of 1986, as amended (the “Code”). As a REIT, we generally will not be subject to U.S. federal income taxes on our net income that is distributed to our stockholders if we distribute at least 90% of our REIT taxable income to our stockholders. REITs are also subject to a number of other organizational and operational requirements. If we fail to qualify as a REIT in any taxable year, our taxable income will be subject to U.S. federal income tax at regular corporate rates (including any applicable alternative minimum tax). Even if we qualify as a REIT, we may be subject to certain U.S. federal, state and local and non-U.S. income taxes. We also will be required to pay a 100% tax on non-arm’s length transactions between us and our taxable REIT subsidiary and on any net income from gain on property that was held for sale to customers in the ordinary course of business.
	Certain of our operations (property management, asset ownership or management, sales of certain assets, etc.) may be conducted through taxable REIT subsidiaries, which are subsidiaries of the operating partnership and each of which we refer to as a TRS. A TRS is a C-corporation for which a REIT and its subsidiary C-corporation have jointly elected for the C-corporation to be a taxable REIT subsidiary of the REIT and therefore is subject to U.S. federal corporate income tax.
	For our taxable REIT subsidiaries, deferred income taxes result from temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for U.S federal income tax purposes, as well as interest and loss carryforwards, and are measured using current enacted tax rates and laws that are expected to be in effect when the differences reverse. We reduce deferred tax assets by recording a valuation allowance when we determine based on available evidence that it is more likely than not that the assets will not be realized.
	The Company recognizes penalties and interest accrued related to unrecognized tax benefits, if any, as income tax expense. To the extent interest and penalties are not assessed with respect to uncertain tax positions, amounts accrued will be reduced and reflected as a reduction of the overall income tax expense. We had no interest expense or penalties related to unrecognized tax benefits for the years ended December 31, 2014, 2013 or 2012.
	We recognize tax benefits of uncertain tax positions only if it is more likely than not that the tax position will be sustained, based solely on its technical merits, with the taxing authority having full knowledge of all relevant information. The measurement of a tax benefit for an uncertain tax position that meets the “more likely than not” threshold is based on a cumulative probability model under which the largest amount of tax benefit recognized is the amount with a greater than 50% likelihood of being realized upon ultimate settlement with the taxing authority having full knowledge of all the relevant information. As of December 31, 2014 and 2013, there were no unrecognized tax benefits. We do not anticipate a significant change to the total amount of unrecognized tax benefits within the next 12 months. Our federal income tax returns and income tax returns for various state and local jurisdictions are subject to examination by the Internal Revenue Service for the year ended December 31, 2010 and subsequent years.
New Accounting Standards	New Accounting Standards
	In February 2013, the Financial Accounting Standards Board (the “FASB”) issued an accounting standard update that requires disclosure of the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount is required under GAAP to be reclassified in its entirety to net income. Additionally, the update requires disclosure of changes in each component of other comprehensive income (“OCI”). The disclosure requirements were retroactively effective for us on January 1, 2013. As this guidance only requires expanded disclosure, the adoption did not have any impact on our Consolidated Financial Statements.
	In April 2014, the FASB issued an ASU that changes the definition of discontinued operations by limiting discontinued operations reporting to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on an entity’s operations and financial results. The amendments in the ASU should be applied prospectively and are effective for us beginning January 1, 2015, with early adoption permitted. We adopted this standard effective January 1, 2014. As a result, we anticipate that fewer of our property dispositions made in the normal course of business will qualify for discontinued operations reporting. Gains on the sale of real estate not qualifying as discontinued operations are presented in “Income (loss) from continuing operations” in our Consolidated Statements of Operations.
	In May 2014, the FASB issued an ASU that requires companies to recognize revenue from contracts with customers based upon the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. The new standard also results in enhanced disclosures about revenue, provides guidance for transactions that were not previously addressed comprehensively and improves guidance for multiple-element arrangements. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is not permitted. The Company is in the process of evaluating the impact this guidance will have on its consolidated financial statements.

	(1)	The fair values of our borrowings were estimated using a discounted cash flow methodology. Credit spreads and market interest rates used to determine the fair value of these instruments are based on unobservable Level 3 inputs which management has determined to be its best estimate of current market values.
	(2)	The carrying amount of our fixed rate debt includes premiums and discounts.
	(3)	The fair value of our interest rate swap is determined using the market standard methodology of netting the discounted future fixed cash flows and the discounted expected variable cash flows based on an expectation of future interest rates derived from Level 2 observable market interest rate curves. We also incorporate a credit valuation adjustment, which is derived using unobservable Level 3 inputs, to appropriately reflect both our nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurement. The asset or liability is included in “Other assets, net” or “Other liabilities,” respectively, in our Consolidated Balance Sheets.

	(1)	Property net operating income (“property NOI”) is defined as rental revenues, including reimbursements, less rental expenses and real estate taxes, which excludes institutional capital management fees, depreciation, amortization, casualty and involuntary conversion gains, impairment, general and administrative expenses, equity in earnings (loss) of unconsolidated joint ventures, interest expense, interest and other income (expense) and income tax benefit (expense) and other taxes. We consider property NOI to be an appropriate supplemental performance measure because property NOI reflects the operating performance of our properties and excludes certain items that are not considered to be controllable in connection with the management of the property such as depreciation, amortization, impairment, general and administrative expenses and interest expense. However, property NOI should not be viewed as an alternative measure of our financial performance since it excludes expenses which could materially impact our results of operations. Further, our property NOI may not be comparable to that of other real estate companies, as they may use different methodologies for calculating property NOI. Therefore, we believe net income (loss) attributable to common stockholders, as defined by GAAP, to be the most appropriate measure to evaluate our overall financial performance.

[1]	The fair value of our interest rate swap is determined using the market standard methodology of netting the discounted future fixed cash flows and the discounted expected variable cash flows based on an expectation of future interest rates derived from Level 2 observable market interest rate curves. We also incorporate a credit valuation adjustment, which is derived using unobservable Level 3 inputs, to appropriately reflect both our nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurement. The asset or liability is included in “Other assets, net” or “Other liabilities,” respectively, in our Consolidated Balance Sheets.
[2]	The fair values of our borrowings were estimated using a discounted cash flow methodology. Credit spreads and market interest rates used to determine the fair value of these instruments are based on unobservable Level 3 inputs which management has determined to be its best estimate of current market values.
[3]	The carrying amount of our fixed rate debt includes premiums and discounts.

[1]	Property net operating income (“property NOI”) is defined as rental revenues, including reimbursements, less rental expenses and real estate taxes, which excludes institutional capital management fees, depreciation, amortization, casualty and involuntary conversion gains, impairment, general and administrative expenses, equity in earnings (loss) of unconsolidated joint ventures, interest expense, interest and other income (expense) and income tax benefit (expense) and other taxes. We consider property NOI to be an appropriate supplemental performance measure because property NOI reflects the operating performance of our properties and excludes certain items that are not considered to be controllable in connection with the management of the property such as depreciation, amortization, impairment, general and administrative expenses and interest expense. However, property NOI should not be viewed as an alternative measure of our financial performance since it excludes expenses which could materially impact our results of operations. Further, our property NOI may not be comparable to that of other real estate companies, as they may use different methodologies for calculating property NOI. Therefore, we believe net income (loss) attributable to common stockholders, as defined by GAAP, to be the most appropriate measure to evaluate our overall financial performance.
