Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The condensed consolidated financial statements include the financial position and results of operations of the Company, the Operating Partnership and its wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for the fair presentation of the financial condition and results of operations for the interim periods presented. The accompanying condensed consolidated financial statements were prepared in accordance with the requirements for interim financial information. Accordingly, these interim financial statements have not been audited and exclude certain disclosures required for annual financial statements. Also, the operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These interim financial statements should be read in conjunction with the audited consolidated financial statements of the Company included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed. Such estimates are based on management’s historical experience and best judgment after considering past, current and expected events and economic conditions. Actual results could differ from management’s estimates.
Significant Accounting Policies	Significant Accounting Policies The accompanying condensed consolidated financial statements were prepared on the basis of the accounting principles described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015, among others.
Recent Accounting Pronouncements	Recent Accounting Pronouncements On May 28, 2014, the Financial Accounting Standards Board (“FASB”) issued a new standard that provides a single, comprehensive model for recognizing revenue from contracts with customers. The new standard could change the way the Company recognizes revenue from construction and development contracts with third party customers. The new standard will be effective for the Company on January 1, 2018. Management is currently evaluating the potential impact of the new revenue recognition standard on the Company’s consolidated financial statements. On February 18, 2015, the FASB issued new consolidation guidance that changes: (i) the identification of variable interests, (ii) the variable interest entity (“VIE”) characteristics for a limited partnership or similar entity and (iii) primary beneficiary determination. The amended guidance also eliminates the presumption that a general partner controls a limited partnership. The Company adopted the guidance on January 1, 2016 with no material impact on the Company’s consolidated financial statements. On February 25, 2016, the FASB issued a new lease standard that requires lessees to recognize most leases in their balance sheets as lease liabilities with corresponding right-of-use assets. The new standard also makes targeted changes to lessor accounting. The new standard will be effective for the Company on January 1, 2019 and requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application with an option to use certain transition relief. Management is currently evaluating the potential impact of the new lease standard on the Company’s consolidated financial statements. On March 10, 2016, the FASB issued new guidance clarifying that the novation of a derivative contract in a hedge accounting relationship does not, in and of itself, require dedesignation of that hedge accounting relationship. Hedge accounting relationships could continue as long as all of the other hedge accounting criteria are met, including the expectation that the hedge will be highly effective when the creditworthiness of the new counterparty to the derivative contract is considered. The new guidance will be effective for the Company on January 1, 2017, and may be applied prospectively, or the Company may use a modified retrospective approach. Management does not expect the adoption of the new guidance to have a material effect on the Company’s financial position or results of operations. On March 17, 2016, the FASB issued new guidance eliminating the requirement that an investor retrospectively apply equity method accounting when an investment that it had accounted for by another method initially qualifies for the equity method. The new guidance is effective for the Company on January 1, 2017. Management is currently evaluating the potential impact of the new guidance on the Company’s consolidated financial statements. On March 30, 2016, the FASB issued new guidance that will change the accounting for certain aspects of share-based payments to employees. Entities will be required to recognize the income tax effects of awards in the income statement when the awards vest or are settled, and allows the Company to account for forfeitures as they occur. The new guidance is effective for the Company on January 1, 2017. Management is currently evaluating the potential impact of the new guidance on the Company’s consolidated financial statements. On June 16, 2016, the FASB issued new guidance that modifies the accounting for recognizing credit losses on financial instruments. This new guidance replaces the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of information to inform credit loss estimates. The new guidance is effective for the Company on January 1, 2020. Management is currently evaluating the potential impact of the new guidance on the Company’s consolidated financial statements. On August 26, 2016, the FASB issued new guidance that addresses eight classification issues related to the statement of cash flows. Early adoption is permitted, including adoption in an interim period. This guidance should be applied retrospectively to each period presented. This new guidance is effective for the Company on January 1, 2018. Management is currently evaluating the potential impact of the new guidance on the Company’s consolidated financial statements.
Operating Property Acquisitions	Operating Property Acquisitions In connection with operating property acquisitions, the Company identifies and recognizes all assets acquired and liabilities assumed at their estimated fair values as of the acquisition date. The purchase price allocations to tangible assets, such as land, site improvements, and buildings and improvements, are presented within income producing property in the condensed consolidated balance sheet and depreciated over their estimated useful lives. Acquired lease intangibles are presented within other assets and liabilities in the condensed consolidated balance sheet and amortized over their respective lease terms. The Company expenses all costs incurred related to operating property acquisitions. The Company values land based on a market approach, looking to recent sales of similar properties, adjusting for differences due to location and the state of entitlement as well as the shape and size of the parcel. Improvements to land are valued using a replacement cost approach, which applies industry standard replacement costs adjusted for geographic specific considerations and reduced by estimated depreciation. The value of buildings acquired is estimated using the replacement cost approach, assuming the buildings were vacant at acquisition. The replacement cost approach considers the composition of the structures acquired, adjusted for an estimate of depreciation. The estimate of depreciation is made considering industry standard information and depreciation curves for the identified asset classes. The value of acquired lease intangibles considers the estimated cost of leasing the properties as if the acquired buildings were vacant, as well as the value of the current leases relative to market-rate leases. The in-place lease value is determined using an estimated total lease-up time and lost rental revenues during such time. The value of current leases relative to market-rate leases is based on market rents obtained for comparable assets in the applicable markets. Given the significance of unobservable inputs used in the valuation of acquired real estate assets, the Company classifies them as Level 3 inputs in the fair value hierarchy.
Derivative Financial Instruments	Derivative Financial Instruments The Company may enter into interest rate derivative contracts to manage exposure to interest rate risks. The Company does not use derivative financial instruments for trading or speculative purposes. Derivative financial instruments are recognized at fair value and presented within other assets and liabilities in the condensed consolidated balance sheets. Gains and losses resulting from changes in the fair value of derivatives that are neither designated nor qualify as hedging instruments are recognized within the change in fair value of interest rate derivatives in the condensed consolidated statements of comprehensive income. For derivatives that qualify as cash flow hedges, the effective portion of the gain or loss is reported as a component of other comprehensive loss and reclassified into earnings in the periods during which the hedged forecasted transaction affects earnings.
Fair Value of Financial Instruments	Fair value measurements are based on assumptions that market participants would use in pricing an asset or a liability. The hierarchy for inputs used in measuring fair value is as follows: Level 1—quoted prices in active markets for identical assets or liabilities Level 2—observable inputs other than quoted prices in active markets for identical assets and liabilities Level 3—unobservable inputs Except as disclosed below, the carrying amounts of the Company’s financial instruments approximate their fair value. Financial assets and liabilities whose fair values are measured on a recurring basis using Level 2 inputs consist of interest rate swaps and caps. The Company measures the fair values of these assets and liabilities based on prices provided by independent market participants that are based on observable inputs using market-based valuation techniques. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. For disclosure purposes, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. The fair value of the Company’s long term debt is sensitive to fluctuations in interest rates. Discounted cash flow analysis based on Level 2 inputs is generally used to estimate the fair value of the Company’s long term debt. Considerable judgment is used to estimate the fair value of financial instruments. The estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized upon disposition of the financial instruments.
