Accounting Policies [Abstract]
Reclassifications	Reclassifications Certain reclassifications have been made to the 2014 financial statements to conform to the 2015 presentation.
Discontinued Operations	Discontinued Operations Effective January 1, 2015, we adopted Accounting Standards Update ("ASU") No. 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" ("ASU 2014-08") for all properties not previously sold. 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. Going forward, we expect the majority of our property dispositions will not qualify as discontinued operations and the results of the dispositions, including gain on sale of real estate, will be presented in Income from Continuing Operations.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In February 2015, the FASB issued ASU No. 2015-02, "Consolidation (Topic 810) - Amendments to the Consolidation Analysis" (“ASU 2015-02”). ASU 2015-02 updates consolidation guidance for legal entities such as limited partnerships, limited liability companies and securitization structures in an attempt to simplify consolidation accounting. ASU 2015-02 eliminates the presumption that a general partner should consolidate a limited partnership, modifies the evaluation of whether limited partnerships are variable interest entities or voting interest entities and adds requirements that limited partnerships must meet to qualify as voting interest entities. ASU 2015-02 is effective for fiscal years beginning after December 15, 2015, with early adoption permitted. The adoption of ASU 2015-02 is not expected to have an impact on our consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs" ("ASU 2015-03"), which amends the current presentation of debt issuance costs in the financial statements. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts, instead of as an asset. The amendments are to be applied retrospectively and are effective for interim and annual periods beginning after December 15, 2015. The adoption of the new guidance is not expected to have a material impact on our consolidated financial statements.

Disclosure of accounting policy for any discontinued operations. The results of operations of a component of an entity that either has been disposed of or is classified as held for sale is reported in discontinued operations if both: (a) the operations and cash flows of the component have been (or will be) eliminated from the ongoing operations of the entity as a result of the disposal transaction and (b) the entity will not have any significant continuing involvement in the operations of the component after the disposal transaction. If the entity elects to allocate interest expense to a discontinued operation, it may disclose its accounting policy for this election and describe its method of allocation.
