Organization, Consolidation and Presentation of Financial Statements [Abstract]
Overview	Overview Organization and Business Description Douglas Emmett, Inc. is a fully integrated, self-administered and self-managed REIT. We are one of the largest owners and operators of high-quality office and multifamily properties in Los Angeles County, California and Honolulu, Hawaii. We focus on owning, acquiring, developing and managing a substantial share of top-tier office properties and premier multifamily communities in neighborhoods that possess significant supply constraints, high-end executive housing and key lifestyle amenities. Through our interest in our Operating Partnership and its subsidiaries, our consolidated JVs and our unconsolidated Funds, we own or partially own, acquire, develop and manage real estate, consisting primarily of office and multifamily properties in Los Angeles, California and Honolulu, Hawaii. As of December 31, 2016 , we owned a Consolidated Portfolio of (i) fifty-nine office properties (including ancillary retail space), which included seven office properties owned by our consolidated JVs, (ii) ten multifamily properties and (iii) fee interests in two parcels of land subject to ground leases from which we earn ground rent income. Alongside our Consolidated Portfolio, we also manage and own equity interests in our unconsolidated Funds, which at December 31, 2016 , owned eight additional office properties, for a combined sixty-seven office properties in our Total Portfolio. The terms "us," "we" and "our" as used in these financial statements refer to Douglas Emmett, Inc. and its subsidiaries on a consolidated basis. Basis of Presentation The accompanying financial statements are the consolidated financial statements of Douglas Emmett, Inc. and its subsidiaries, including our Operating Partnership and our consolidated JVs. All significant intercompany balances and transactions have been eliminated in our consolidated financial statements. Our Operating Partnership and consolidated JVs are VIEs and we are the primary beneficiary. As of December 31, 2016 , the total consolidated assets, liabilities and equity of the VIEs was $7.61 billion (of which $7.21 billion related to investment in real estate), $4.60 billion and $3.01 billion (of which $1.09 billion related to noncontrolling interest), respectively. During the third quarter of 2016, we sold a property which was classified as real estate held for sale in our consolidated balance sheets. The carrying value in the comparable period has been reclassified to conform to the current period presentation. See Note 3 for information regarding the property that we sold. The accompanying financial statements have been prepared pursuant to the rules and regulations of the SEC in conformity with US GAAP as established by the FASB in the ASC. The accompanying financial statements include, in our opinion, all adjustments, consisting of normal recurring adjustments, necessary to present fairly the financial information set forth therein. Any reference to the number of properties, square footage, per square footage amounts, apartment units and geography, are unaudited and outside the scope of our independent registered public accounting firm’s audit of our financial statements in accordance with the standards of the PCAOB.

Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	Summary of Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. Investment in Real Estate We account for acquisitions of properties as business combinations using the purchase method, and include the results of operations of the acquired properties in our results of operations from their respective dates of acquisition. We expense transaction costs related to acquisitions when they are incurred. We estimate the purchase price allocation of acquired properties, which is based upon our estimates of future cash flows and other valuation techniques, to allocate the purchase price among: (i) land, (ii) buildings and improvements, (iii) tenant improvements and identifiable intangible assets such as in-place at-market leases, and (iv) acquired above- and below-market ground and tenant leases (including for renewal options). We estimate the fair values of the tangible assets on an ‘‘as-if-vacant’’ basis. The estimated fair value of acquired in-place at-market leases are the estimated costs to lease the property to the occupancy level at the date of acquisition, including the fair value of leasing commissions and legal costs. We evaluate the time period over which we expect such occupancy level to be achieved and include an estimate of the net operating costs (primarily real estate taxes, insurance and utilities) incurred during the lease-up period. Above- and below-market ground and tenant leases are recorded as an asset or liability based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between the contractual amounts to be paid or received pursuant to the in-place ground or tenant leases, respectively, and our estimate of fair market rental rates for the corresponding in-place leases, over the remaining non-cancelable term of the lease. Our initial valuations and allocations are subject to change until the allocation is finalized within 12 months after the acquisition date. See Note 3 for our property acquisition disclosures. Buildings and improvements are depreciated on a straight-line basis using an estimated life of forty years for buildings and fifteen years for improvements, and are carried on our balance sheet, offset by the related accumulated depreciation and any impairment charges, until they are sold. Tenant improvements are depreciated on a straight-line basis over the life of the related lease, with any remaining balance depreciated in the period of any early termination of that lease. Acquired in-place leases are amortized on a straight line basis over the weighted average remaining term of the acquired in-place leases, and are carried on our balance sheet, offset by the related accumulated amortization, until the related building is either sold or impaired. Leasing intangibles are amortized on a straight-line basis over the related lease term, with any remaining balance amortized in the period of any early termination of that lease. Acquired above- and below-market tenant leases are amortized/accreted on a straight line basis over the life of the related lease and recorded as either an increase (for below-market leases) or a decrease (for above-market leases) to rental revenue. Acquired above- and below-market ground leases, from which we earn ground rent income, are amortized/accreted on a straight line basis over the life of the related lease and recorded either as an increase (for below-market leases) or a decrease (for above-market leases) to rental revenue. Acquired above- and below-market ground leases, for which we incur ground rent expense, are accreted/ amortized over the life of the related lease and recorded either as an increase (for below-market leases) or a decrease (for above-market leases) to expense. When assets are sold or retired, their cost and related accumulated depreciation or amortization are removed from our balance sheet with the resulting gains or losses, if any, reflected in our results of operations for the respective period. Repairs and maintenance are recorded as expense when incurred. Properties are classified as held for sale in the consolidated balance sheets when they meet certain requirements, including the approval of the sale of the property, the marketing of the property for sale, and our expectation that the sale will likely occur within the next 12 months. Properties classified as held for sale are carried at the lower of their carrying value or fair value less costs to sell, and we also cease to depreciate the property. Costs incurred during the period of construction of real estate are capitalized. Cost capitalization of development and redevelopment activities begins during the predevelopment period, which we define as the activities that are necessary to begin the development of the property. We cease capitalization upon substantial completion of the project, but no later than one year from cessation of major construction activity. We also cease capitalization when activities necessary to prepare the property for its intended use have been suspended. Capitalized costs are included in Property under development in our Consolidated Balance Sheets. Once major construction activity has ceased and the development or redevelopment property is in the lease-up phase, the capitalized costs are transferred to (i) Land, (ii) Building and improvements and (iii) Tenant improvements and lease intangibles on our Consolidated Balance Sheets as the historical cost of the property. During 2016 , 2015 and 2014 , we capitalized $31.6 million , $3.7 million and $4.3 million of costs related to our developments, respectively, which included $1.2 million , $940 thousand and $294 thousand of capitalized interest, respectively. Investment in Unconsolidated Real Estate Funds We manage and hold equity interests in two Funds: Fund X and Partnership X. As of December 31, 2016 , we held a 68.61% interest in Fund X and 24.25% interest in Partnership X. We account for our investments in the Funds using the equity method because we have significant influence but not control over the Funds, and our Funds do not qualify as VIEs. Our investment balance includes our share of the net assets of the combined Funds, acquisition basis difference, additional basis for capital raising costs, our share of our Funds' accumulated other comprehensive income (loss) related to our Funds' derivatives, and notes receivable from our Funds. As of December 31, 2016 and 2015 , the total basis difference was $2.9 million . See Note 5 for our Fund disclosures. Impairment of Long-Lived Assets We periodically assess whether there has been any impairment in the carrying value of our properties whenever events or changes in circumstances indicate that the carrying value of a property may not be recoverable. An impairment charge is recorded when events or change in circumstances indicate that a decline in the fair value below the carrying value has occurred and such decline is other-than-temporary. Recoverability of the carrying value of our properties is measured by a comparison of the carrying value to the undiscounted future cash flows expected to be generated by the property. If the carrying value exceeds the estimated undiscounted future cash flows, an impairment loss is recorded equal to the difference between the properties carrying value and its fair value based on the estimated discounted future cash flows. We also perform a similar periodic assessment for our investments in our Funds. Based upon such periodic assessments, no impairments occurred during 2016 , 2015 or 2014 . Cash and Cash Equivalents We consider short-term investments with maturities of three months or less when purchased to be cash equivalents. Revenue and Gain Recognition We recognize revenue when four basic criteria are met: (i) persuasive evidence of an arrangement exists, (ii) services are rendered, (iii) the fee is fixed and determinable and (iv) collectibility is reasonably assured. All of our tenant leases are classified as operating leases. For all lease terms exceeding one year, rental income is recognized on a straight-line basis over the term of the lease. Deferred rent receivables represent rental revenue recognized on a straight-line basis in excess of billed rents. Rental revenue from month-to-month leases or leases with no scheduled rent increases or other adjustments are recognized on a monthly basis when earned. Lease termination fees, which are included in rental revenues in the consolidated statements of operations, are recognized when the related lease is canceled and we have no continuing obligation to provide services to the former tenant. We recognized lease termination revenue of $2.4 million , $2.2 million , $2.6 million during 2016 , 2015 and 2014 , respectively. Tenant improvements constructed by us and reimbursed by tenants are recorded as our assets, and the related revenue, which is included in rental revenues in the consolidated statements of operations, is recognized over the related lease term. We recognized revenue for leasehold improvements of $2.6 million , $1.9 million , $1.7 million during 2016 , 2015 and 2014 , respectively. Estimated tenant recoveries for real estate taxes, common area maintenance and other recoverable operating expenses are recognized as revenue on a gross basis in the period that the recoverable expenses are incurred. Subsequent to year-end, we perform reconciliations on a lease-by-lease basis and bill or credit each tenant for any cumulative annual adjustments. Recognition of gains on sales of investments in real estate requires that we measure the timing of a sale against various criteria related to the terms of the transaction, as well as any continuing involvement in the form of management or financial assistance associated with the property. If the sales criteria are not met, we defer gain recognition and account for the continued operations of the property by applying the finance, profit-sharing or leasing method. If the sales criteria have been met, we further analyze whether profit recognition is appropriate using the full accrual method. If the criteria to recognize profit using the full accrual method have not been met, we defer the gain and recognize it when the criteria are met or use the installment or cost recovery method as appropriate under the circumstances. See Note 3 for information regarding a property that we sold during 2016 . Allowances for Tenant Receivables and Deferred Rent Receivables We carry tenant receivables and deferred rent receivables net of allowances. Tenant receivables consist primarily of amounts due for contractual lease payments and reimbursements of common area maintenance expenses, property taxes, and other costs recoverable from tenants. Deferred rent receivables represent the amount by which the cumulative straight-line rental revenue recorded to date exceeds cash rents billed to date under the lease agreement. We consider many factors when evaluating the level of reserves necessary, including evaluations of individual tenant receivables, historical loss activity, current economic conditions and other relevant factors. As of December 31, 2016 and 2015 , we had tenant receivable allowances of $2.7 million and $2.2 million , respectively, and deferred rent receivable allowances of $5.1 million and $6.0 million , respectively. We generally require letters of credit or cash security deposits from our tenants. As of December 31, 2016 and 2015 , we held $25.5 million and $14.7 million of letters of credit, and $46.0 million and $38.7 million of cash security deposits, respectively, as security from our tenants. The net impact on our results of operations from changes in our tenant receivable allowance, net of charges and recoveries, was a decrease of $422 thousand , a decrease of $ 223 thousand and an increase of $ 461 thousand d uring 2016 , 2015 and 2014 , respectively. The net impact on our results of operations from changes in our deferred rent receivable allowance, net of charges and recoveries, was an increase of $ 898 thousand , a decrease of $ 242 thousand and an increase of $ 2.4 million d uring 2016 , 2015 and 2014 , respectively. Insurance Recoveries Insurance recoveries related to property damage are recorded as other income when payment is either received or receipt is determined to be probable. Interest Income Interest income on our notes receivable is recognized over the life of the respective notes using the effective interest method and recognized on the accrual basis. Interest income is included in other income in the consolidated statements of operations. See Note 5 for details regarding our notes receivable. Loan Costs Loan costs incurred directly with the issuance of secured notes payable and revolving credit facilities are deferred and amortized to interest expense over the respective loan or credit facility term. Any unamortized amounts are written off upon early repayment of the secured notes payable, and the related cost and accumulated amortization are removed from our balance sheet. To the extent that a refinancing is considered an exchange of debt with the same lender, we account for loan costs based upon whether the old debt is determined to be modified or extinguished for accounting purposes. If the old debt is determined to be modified then we (i) continue to defer and amortize any unamortized deferred loan costs associated with the old debt at the time of the modification over the new term of the modified debt, (ii) defer and amortize the lender costs incurred in connection with the modification over the new term of the modified debt, and (iii) expense all other costs associated with the modification. If the old debt is determined to be extinguished then we (i) write off any unamortized deferred loan costs associated with the extinguished debt at the time of the extinguishment and remove the related cost and accumulated amortization from our balance sheet, (ii) expense all lender costs associated with the extinguishment, and (iii) defer and amortize all other costs incurred directly in connection with the extinguishment over the term of the new debt. In circumstances where we modify or exchange our revolving credit facility with the same lender, we account for the loan costs based upon whether the borrowing capacity (defined as the product of the remaining term and the maximum available credit) of the new arrangement is (a) greater than or equal to the borrowing capacity of the old arrangement, or (b) less than the borrowing capacity of the old arrangement. If the borrowing capacity of the new arrangement is greater than or equal to the borrowing capacity of the old arrangement, then we (i) continue to defer and amortize the unamortized deferred loan costs from the old arrangement over the term of the new arrangement and (ii) defer all lender and other costs incurred directly in connection with the new arrangement over the term of the new arrangement. If the borrowing capacity of the new arrangement is less than the borrowing capacity of the old arrangement, then we (i) amortize any unamortized deferred loan costs at the time of the change related to the old arrangement in proportion to the decrease in the borrowing capacity of the old arrangement and (ii) defer all lender and other costs incurred directly in connection with the new arrangement over the term of the new arrangement. Deferred loan costs are presented in the balance sheet as a direct deduction from the carrying amount of our secured notes payable and revolving credit facility. All loan costs expensed and deferred loan costs amortized are included in interest expense in our consolidated statements of operations. See Note 7 for our deferred loan cost disclosures. Derivative Contracts We make use of interest rate swap and interest rate cap contracts to manage the risk associated with changes in interest rates on our floating-rate debt. When we enter into a floating-rate term loan, we generally enter into an interest rate swap agreement for the equivalent principal amount, for a period covering the majority of the loan term, which effectively converts our floating-rate debt to a fixed-rate basis during that time. In limited instances, we make use of interest rate caps to limit our exposure to interest rate increases on our floating-rate debt. We do not speculate in derivatives and we do not make use of any other derivative instruments. When we enter into derivative agreements, we generally elect to designate them as cash flow hedges for accounting purposes. Changes in fair value of hedging instruments designated as cash flow hedges are recorded in accumulated other comprehensive income (loss) (AOCI), which is a component of equity outside of earnings, and any hedge ineffectiveness is recorded as interest expense. For our Funds' hedging instruments designated as cash flow hedges, we record our share of the changes in fair value of the hedging instrument in AOCI and our share of any hedge ineffectiveness is recorded in income, including depreciation, from unconsolidated real estate funds in our consolidated statements of operations. Amounts recorded in AOCI related to our designated hedges are reclassified to interest expense as interest payments are made on the hedged floating rate debt. Amounts reported in AOCI related to our Funds' hedges are reclassified to income, including depreciation, from unconsolidated real estate funds, as interest payments are made by our Funds on their hedged floating rate debt. Changes in fair value of hedging instruments not designated as cash flow hedges are recorded as interest expense. We present our derivatives on the balance sheet at fair value on a gross basis. Our share of the fair value of our Funds' derivatives is included in our investment in unconsolidated real estate funds on our consolidated balance sheet. See Note 9 for our derivative disclosures. Stock-Based Compensation We account for stock-based compensation, including stock options and LTIP Units, using the fair value method of accounting. The estimated fair value of stock options and LTIP Units is amortized over any vesting period. See Note 12 for our stock-based compensation disclosures. EPS We calculate basic EPS by dividing the net income attributable to common stockholders for the period by the weighted average number of common shares outstanding during the period. We calculate diluted EPS by dividing the net income attributable to common stockholders for the period by the weighted average number of common shares and dilutive instruments outstanding during the period using the treasury stock method. Unvested LTIP Units contain nonforfeitable rights to dividends and we account for them as participating securities and include them in the computation of basic and diluted EPS using the two-class method. See Note 11 for our EPS disclosures. Segment Information Segment information is prepared on the same basis that our management reviews information for operational decision-making purposes. We operate two business segments: the acquisition, development, ownership and management of office real estate, and the acquisition, development, ownership and management of multifamily real estate. The services for our office segment include primarily rental of office space and other tenant services, including parking and storage space rental. The services for our multifamily segment include primarily rental of apartments and other tenant services, including parking and storage space rental. See Note 14 for our segment disclosures. Income Taxes We have elected to be taxed as a REIT under the Code, commencing with our initial taxable year ended December 31, 2006. To qualify as a REIT, we are required (among other things) to distribute at least 90% of our REIT taxable income to our stockholders and meet various other requirements imposed by the Code relating to matters such as operating results, asset holdings, distribution levels and diversity of stock ownership. Provided that we qualify for taxation as a REIT, we are generally not subject to corporate-level income tax on the earnings distributed currently to our stockholders that we derive from our REIT qualifying activities. If we fail to qualify as a REIT in any taxable year, and are unable to avail ourselves of certain savings provisions set forth in the Code, all of our taxable income would be subject to federal income tax at regular corporate rates, including any applicable alternative minimum tax. We have elected to treat two of our subsidiaries as TRS, which generally may engage in any business, including the provision of customary or non-customary services to our tenants. A TRS is treated as a regular corporation and is subject to federal income tax and applicable state income and franchise taxes at regular corporate rates. Neither of our TRS had any significant tax provisions or deferred income tax items for 2016 , 2015 or 2014 . Our subsidiaries (other than our TRS), including our Operating Partnership, are partnerships, disregarded entities, QRS or REITs, as applicable, for federal income tax purposes. Under applicable federal and state income tax rules, the allocated share of net income or loss from disregarded entities or flow-through entities is reportable in the income tax returns of the respective owners. Accordingly, no income tax provision is included in our consolidated financial statements. New Accounting Pronouncements Changes to GAAP are established by the FASB in the form of ASUs. We consider the applicability and impact of all ASUs. Recently Issued and Adopted Accounting Pronouncements In January 2015, the FASB issued ASU No. 2015-01, "Income Statement—Extraordinary and Unusual Items (Subtopic 225-20)", which eliminates the concept of extraordinary items from GAAP. The FASB issued this ASU as part of its initiative to reduce complexity in accounting standards (the Simplification Initiative). The objective of the Simplification Initiative is to identify, evaluate, and improve areas of GAAP for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided to the users of financial statements. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, which for us was the first quarter of 2016. We adopted the ASU in the first quarter of 2016 and it did not have a material impact on our financial position, results of operations or disclosures. In February 2015, the FASB issued ASU No. 2015-02, "Amendments to the Consolidation Analysis (Consolidation - Topic 810)", which provides guidance regarding the consolidation of certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, which for us was the first quarter of 2016. We adopted the ASU in the first quarter of 2016 and it did not have a material impact on our financial position, results of operations or disclosures. In September 2015, the FASB issued ASU No. 2015-16, "Simplifying the Accounting for Measurement-Period Adjustments", which amends "Business Combinations" (Topic 805). The ASU requires that an acquirer (i) recognize adjustments to provisional amounts from business combinations that are identified during the measurement period in the reporting period in which the adjustment amounts are determined, (ii) record, in the same period’s financial statements, the effect on earnings, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date and (iii) disclosure of the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, which for us was the first quarter of 2016. We adopted the ASU in the first quarter of 2016 and it did not have a material impact on our financial position, results of operations or disclosures. In March 2016, the FASB issued ASU No. 2016-05, "Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships", which amends "Derivatives and Hedging" (Topic 815). The ASU provides guidance on the effect of derivative contract novations on existing hedge accounting relationships. The ASU clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under Topic 815, does not in and of itself require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. The ASU is effective for fiscal years beginning after December 15, 2016, and interim periods within those years, which for us would be the first quarter of 2017, and early adoption is permitted. We adopted the ASU in the first quarter of 2016 and it did not have a material impact on our financial position, results of operations or disclosures. Recently Issued Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, "Leases" (Topic 842). The main difference between previous GAAP and Topic 842 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under prevailing GAAP. The accounting applied by a lessor is largely unchanged from that applied under prevailing GAAP. For example, the vast majority of operating leases will remain classified as operating leases, and lessors will continue to recognize lease income for those leases on a straight-line basis over the lease term. Topic 842 requires an entity to separate the lease components from the non-lease components (for example, maintenance services or other activities that transfer a good or service to the customer) in a contract. Only the lease components must be accounted for in accordance with Topic 842. The consideration in the contract is allocated to the lease and non-lease components on a relative standalone price basis (for lessees) or in accordance with the allocation guidance in Topic 606 (for lessors). Topic 842 defines capitalizable initial direct costs of a lease as costs that would not have been incurred had the lease not been obtained. Costs to negotiate or arrange a lease that would have been incurred regardless of whether the lease was obtained, such as fixed employee salaries, are not initial direct costs, and may not be capitalized. The ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those years, which for us would be the first quarter of 2019, and early adoption is permitted. In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers" (Topic 606), which provides guidance for the accounting of revenue from contracts with customers. The guidance supersedes the revenue recognition requirements in Topic 605, "Revenue Recognition", and most industry-specific guidance throughout the Industry Topics of the Codification. In March 2016, the FASB issued ASU No. 2016-08, "Principal versus Agent Considerations (Reporting Revenue Gross versus Net)" which amends "Revenue from Contracts with Customers" (Topic 606). The ASU clarifies the guidance for principal versus agent considerations. In April 2016, the FASB issued ASU No. 2016-10, "Identifying Performance Obligations and Licensing" which amends "Revenue from Contracts with Customers" (Topic 606). The ASU provides guidance for identifying performance obligations and licensing. In May 2016, the FASB issued ASU No. 2016-12, "Narrow-Scope Improvements and Practical Expedients" which amends "Revenue from Contracts with Customers" (Topic 606). The ASU provides guidance for a variety of revenue recognition related topics. In August 2015, the FASB issued ASU No. 2015-14, which defers the effective date of ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) by one year. As a result, the various ASUs listed above are now effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, which for us is the first quarter of 2018. Earlier application is permitted for fiscal years beginning after December 15, 2016, including interim reporting periods within those years, which for us is the first quarter of 2017. The amendments in this ASU should be applied retrospectively. We are not planning on early adopting the ASU and we expect to use the modified retrospective method of adoption. We are currently evaluating the potential impact to our accounting, particularly with respect to our tenant recovery revenues, and whether such changes will be material to our future results of operations and financial position. As noted above, ASU 2016-02 "Leases" requires that non-lease components such as tenant recovery revenues be accounted for in accordance with ASU 2014-09, which means that the classification and timing of our tenant recovery revenues could be impacted. In June 2016, the FASB issued ASU No. 2016-13, "Measurement of Credit Losses on Financial Instruments" which amends "Financial Instruments-Credit Losses" (Topic 326). The ASU provides guidance for measuring credit losses on financial instruments. The ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those years, which for us would be the first quarter of 2020, and early adoption is permitted commencing the first quarter of 2019. The amendments in this ASU should be applied retrospectively. We are currently evaluating the impact of this ASU. In August 2016, the FASB issued ASU No. 2016-15, "Classification of Certain Cash Receipts and Cash Payments" which amends "Statement of Cash Flows" (Topic 230). The ASU provides guidance regarding the presentation of certain types of transactions in the statement of cash flows. The ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those years, which for us would be the first quarter of 2018, and early adoption is permitted. The amendments in this ASU should be applied retrospectively. We do not expect the ASU to have a material impact on our statement of cash flows. In October 2016, the FASB issued ASU No. 2016-17, "Interests Held Through Related Parties That Are Under Common Control". The ASU provides guidance regarding consolidation of VIE's. The ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within those years, which for us would be the first quarter of 2017. The amendments in this ASU should be applied retrospectively. We do not expect the ASU to have a material impact on our financial position, results of operations or disclosures. In November 2016, the FASB issued ASU No. 2016-18, "Restricted Cash". The ASU provides guidance regarding the presentation of restricted cash in the statement of cash flows. The ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those years, which for us would be the first quarter of 2018. The amendments in this ASU should be applied retrospectively. We do not expect the ASU to have a material impact on our statement of cash flows. In January 2017, the FASB issued ASU No. 2017-01, "Clarifying the Definition of a Business". The ASU provides guidance regarding the definition of a business with the objective of providing guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those years, which for us would be the first quarter of 2018. The ASU should be applied prospectively and early adoption is permitted. The ASU will impact our future results of operations and cash flows because we expect that our property acquisitions will be accounted for as asset purchases, and the related acquisition expenses capitalized as part of the respective asset. We historically accounted for our property acquisitions as business acquisitions and expensed the related acquisition

As of July 21, 2016 , we had contributed fifty-five percent of the equity to the JV, which was reduced to twenty -percent when we sold thirty-five percent to a third party investor for $51.6 million , which included $194 thousand to compensate us for our costs of holding the investment. We recognized a gain of $587 thousand on the sale, which is included in Gains on sales of investments in real estate in our consolidated statements of operations. In addition to purchasing a thirty-five percent interest from us, investors contributed $139.8 million to the JV. As of December 31, 2016 , including the effect of the sale of our interest, investors hold an aggregate of eighty -percent of the capital interests in the JV. As part of the acquisitions, the JV borrowed a total of $146.0 million under a three year, interest only, non-recourse loan bearing interest at LIBOR + 1.55% . The loan is secured by the acquired properties. See Note 7 . The table below (in thousands) summarizes our purchase accounting for the acquisitions.

Stockholders' Equity Attributable to Parent [Abstract]
Equity	Equity Equity Transactions During 2016 , we (i) acquired 1.8 million OP Units in exchange for issuing an equal number of shares of our common stock to the holders of OP Units, (ii) acquired 25 thousand OP Units for $826 thousand in cash, at an average price of $33.05 per OP Unit, (iii) issued 1.5 million shares of our common stock for the exercise of 7.6 million stock options on a net settlement basis (net of the exercise price and related taxes), (iv) sold 1.4 million shares of our common stock in open market transactions under our ATM program for net proceeds of $49.4 million , after commissions and other expenses. We also created two JVs to acquire various properties: (i) in the JV which acquired the Westwood Portfolio, investors acquired an aggregate of seventy -percent of the capital interests, as a result of contributing $320.0 million directly to the JV for a forty -percent interest and acquiring a thirty -percent interest from us for $241.1 million , (resulting in a gain of $1.1 million ), and (ii) in the JV which acquired properties during the third quarter, investors acquired an aggregate of eighty -percent of the capital interests, as a result of contributing $139.8 million directly to the JV and acquiring a thirty-five -percent interest from us for $51.6 million (resulting in a gain of $587 thousand ). See Note 3 for more information regarding these JVs. During 2015 , we (i) acquired 1.8 million OP Units in exchange for issuing to the holders of the OP Units an equal number of shares of our common stock, (ii) issued 274 thousand shares of our common stock for the excise of options for net proceeds of $4.3 million at an average price of $15.58 per share and (iii) issued 34 thousand OP Units valued at $1 million in connection with the acquisition of land (Harbor Court Land) under one of our office buildings. See Note 3 . During 2014 , we (i) acquired 2.2 million OP Units in exchange for issuing to the holders of the OP Units an equal number of shares of our common stock, (ii) acquired 120 thousand OP Units for cash for a total purchase price of $2.8 million at an average price of $23.56 per unit, (iii) cash-settled options covering 691 thousand shares of our common stock for a total cost of $4.5 million at an average price of $6.55 per option and (iv) issued 40 thousand shares of our common stock for the exercise of options for net proceeds of $603 thousand , for an average price of $15.05 per share. Noncontrolling Interests Our noncontrolling interests consist of interests in our Operating Partnership and consolidated JVs which are not owned by us. Noncontrolling interests in our Operating Partnership consist of OP Units and fully-vested LTIP Units, and represented approximately 14% of our Operating Partnership's total interests as of December 31, 2016 when we and our Operating Partnership had 151.5 million shares of common stock and 25.7 million OP Units and fully-vested LTIP Units outstanding. A share of our common stock, an OP Unit and an LTIP Unit (once vested and booked up) have essentially the same economic characteristics, sharing equally in the distributions from our Operating Partnership. Investors who own OP Units have the right to cause our Operating Partnership to redeem their OP Units for an amount of cash per unit equal to the market value of one share of our common stock at the date of redemption, or, at our election, exchange their OP Units for shares of our common stock on a one-for-one b asis. LTIP Units have been granted to our key employees and non-employee directors as part of their compensation. These awards generally vest over the service period and once vested can generally be converted to OP Units.

Share-based Compensation [Abstract]
Share-Based Compensation	Stock-Based Compensation 2016 Omnibus Stock Incentive Plan The Douglas Emmett, Inc. 2016 Omnibus Stock Incentive Plan, our stock incentive plan (our "2016 Plan"), permits us to make grants of incentive stock options, non-qualified stock options, stock appreciation rights, deferred stock awards, restricted stock awards, dividend equivalent rights and other stock-based awards. We had an aggregate of 6.9 million shares available for grant as of December 31, 2016 . Awards such as LTIP Units, deferred stock and restricted stock, which deliver the full value of the underlying shares are counted against the Plan limits as two shares. Awards such as stock options and stock appreciation rights are counted as one share. The number of shares reserved under our Plan is also subject to adjustment in the event of a stock split, stock dividend or other change in our capitalization. Shares of stock underlying any awards that are forfeited, canceled or otherwise terminated (other than by exercise) are added back to the shares of stock available for future issuance under the Plan. For options exercised, our policy is to issue common stock on a net settlement basis - net of the exercise price and related taxes. Until it expired in 2016, we made grants under our 2006 Omnibus Stock Incentive Plan (our "2006 Plan"), which was substantially similar to our 2016 Plan. No further awards may be granted under our 2006 Plan, although awards granted under the 2006 Plan in the past and which are still outstanding will continue to be governed by the terms of our 2006 Plan. Our 2016 and 2006 Plans (the "Plans") are administered by the compensation committee of our board of directors. The compensation committee may interpret our Plans and make all determinations necessary or desirable for the administration of our Plans. The committee has full power and authority to select the participants to whom awards will be granted, to make any combination of awards to participants, to accelerate the exercisability or vesting of any award and to determine the specific terms and conditions of each award, subject to the provisions of our 2016 Plan. All full-time and part-time officers, employees, directors and other key persons (including consultants and prospective employees) are eligible to participate in our 2016 Plan. We have made certain awards in the form of a separate series of units of limited partnership interests in our Operating Partnership called LTIP Units, which can be granted either as free-standing awards or in tandem with other awards under our stock incentive plan. Our LTIP Units are valued by reference to the value of our common stock at the time of grant, and are subject to such conditions and restrictions as the compensation committee may determine, including continued employment or service, and/or achievement of pre-established performance goals, financial metrics and other objectives. Once vested, LTIP Units can generally be converted to OP Units on a one for one basis. Employee Awards We grant stock-based compensation in the form of LTIP Units as a part of our annual incentive compensation to various employees each year, a portion which vests at the date of grant, and the remainder which vests in three equal annual installments over the three calendar years following the grant date. Compensation expense for LTIP Units which are not vested at the grant date is recognized on a straight-line basis over the requisite service period for each separately vesting portion of the award. We have also made long-term grants in the form of LTIP Units to certain employees. The grants generally vest in equal annual installments over four or five calendar years following the grant date, and some of these grants include a portion which vests at the date of grant. In aggregate, we granted 704 thousand , 887 thousand and 1.1 million LTIP Units to employees during 2016 , 2015 and 2014 , respectively. Non-Employee Director Awards We granted 35 thousand , 35 thousand and 15 thousand LTIP Units to our non-employee directors during 2016 , 2015 and 2014 , respectively, which vest ratably over the year of grant in lieu of cash retainers. In the past, we made long-term grants of LTIP Units to our non-employee directors which vested over the following three years , and during 2015 we made a proportional grant to a new director who joined our board of 1 thousand LTIP units, which vested during the remainder of 2015. Compensation Expense Total stock-based compensation expense, net of capitalized amounts, was $17.4 million , $15.2 million and $13.7 million during 2016 , 2015 and 2014 , respectively. Certain amounts of stock-based compensation expense are capitalized for employees who provide leasing and construction services. We capitalized $1.5 million , $1.4 million , and $1.1 million during 2016 , 2015 and 2014 , respectively. At December 31, 2016 , the total unrecognized stock-based compensation expense for unvested LTIP Unit awards was $18.3 million , which will be recognized over a weighted-average term of two years .

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Our estimates of the fair value of financial instruments were determined using available market information and widely used valuation methods. Considerable judgment is necessary to interpret market data and determine an estimated fair value. The use of different market assumptions or valuation methods may have a material effect on the estimated fair values. The FASB fair value framework hierarchy distinguishes between assumptions based on market data obtained from sources independent of the reporting entity, and the reporting entity’s own assumptions about market-based inputs. The hierarchy is as follows: Level 1 - inputs utilize unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 - inputs are observable either directly or indirectly for similar assets and liabilities in active markets. Level 3 - inputs are unobservable assumptions generated by the reporting entity As of December 31, 2016 , we did not have any fair value estimates of financial instruments using Level 3 inputs. Financial instruments disclosed at fair value Short term financial instruments: The carrying amounts for cash and cash equivalents, tenant receivables, revolving credit line, interest payable, accounts payable, security deposits and dividends payable approximate fair value because of the short-term nature of these instruments. Secured notes payable : See Note 7 for the details of our secured notes payable. We estimate the fair value of our secured notes payable, which includes the secured notes payable of our consolidated JVs, by calculating the credit-adjusted present value of the principal and interest payments for each secured note payable. The calculation incorporates observable market interest rates which we consider to be Level 2 inputs, assumes that the loans will be outstanding through maturity, and excludes any maturity extension options. The table below presents (in thousands) the estimated fair value of our secured notes payable: Secured Notes Payable: December 31, 2016 December 31, 2015 Fair value $ 4,429,224 $ 3,691,075 Carrying value $ 4,408,083 $ 3,634,163 Financial instruments measured at fair value Derivative instruments: See Note 9 for the details of our derivatives. We present our derivatives on the balance sheet at fair value, on a gross basis, excluding accrued interest. We estimate the fair value of our derivative instruments by calculating the credit-adjusted present value of the expected future cash flows of each derivative. The calculation incorporates the contractual terms of the derivatives, observable market interest rates which we consider to be Level 2 inputs, and credit risk adjustments to reflect the counterparty's as well as our own nonperformance risk. Our derivatives are not subject to master netting arrangements. The table below presents (in thousands) the estimated fair value of our derivatives: December 31, 2016 December 31, 2015 Derivative Assets: Fair value - c onsolidated derivatives (1) $ 35,656 $ 4,830 Fair value - unconsolidated Funds' derivatives (2) $ 3,605 $ 837 Derivative Liabilities: Fair value - c onsolidated derivatives (1) $ 6,830 $ 16,310 Fair value - unconsolidated Funds' derivatives (2) $ — $ — ___________________________________________________________________________________ (1) Consolidated derivatives, which include 100% , not our pro-rata share, of our consolidated JVs' derivatives, are included in interest rate contracts in our consolidated balance sheet. The fair value excludes accrued interest which is included in interest payable in the consolidated balance sheet. (2) Represents 100% , not our pro-rata share, of our unconsolidated Funds derivatives.

Segment Reporting

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting Segment information is prepared on the same basis that our management reviews information for operational decision-making purposes. We operate in two business segments: (i) the acquisition, development, ownership and management of office real estate and (ii) the acquisition, development, ownership and management of multifamily real estate. The services for our office segment primarily include rental of office space and other tenant services, including parking and storage space rental. The services for our multifamily segment include rental of apartments and other tenant services, including parking and storage space rental. Asset information by segment is not reported because we do not use this measure to assess performance or make decisions to allocate resources. Therefore, depreciation and amortization expense is not allocated among segments. General and administrative expenses and interest expense are not included in segment profit as our internal reporting addresses these items on a corporate level. Segment profit is not a measure of operating income or cash flows from operating activities as measured by GAAP, it is not indicative of cash available to fund cash needs, and it should not be considered as an alternative to cash flows as a measure of liquidity. Not all companies may calculate segment profit in the same manner. We consider segment profit to be an appropriate supplemental measure to net income because it can assist both investors and management in understanding the core operations of our properties. The table below presents (in thousands) the operating activity of our reportable segments: Year Ended December 31, 2016 2015 2014 Office Segment Total office revenues $ 645,633 $ 540,975 $ 519,405 Office expenses (214,546 ) (186,556 ) (181,160 ) Office Segment profit 431,087 354,419 338,245 Multifamily Segment Total multifamily revenues 96,918 94,799 80,117 Multifamily expenses (23,317 ) (23,862 ) (20,664 ) Multifamily Segment profit 73,601 70,937 59,453 Total profit from all segments $ 504,688 $ 425,356 $ 397,698 The table below (in thousands) is a reconciliation of the total profit from all segments to net income attributable to common stockholders: Year Ended December 31, 2016 2015 2014 Total profit from all segments $ 504,688 $ 425,356 $ 397,698 General and administrative (34,957 ) (30,496 ) (27,332 ) Depreciation and amortization (248,914 ) (205,333 ) (202,512 ) Other income 8,759 15,228 17,675 Other expenses (6,609 ) (6,470 ) (7,095 ) Income, including depreciation, from unconsolidated real estate funds 7,812 7,694 3,713 Interest expense (146,148 ) (135,453 ) (128,507 ) Acquisition-related expenses (2,868 ) (1,771 ) (786 ) Income before gains 81,763 68,755 52,854 Gains on sales of investments in real estate 14,327 — — Net income 96,090 68,755 52,854 Less: Net income attributable to noncontrolling interests (10,693 ) (10,371 ) (8,233 ) Net income attributable to common stockholders $ 85,397 $ 58,384 $ 44,621

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Guarantees	Commitments, Contingencies and Guarantees Legal Proceedings From time to time, we are party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of our business. Excluding ordinary, routine litigation incidental to our business, we are not currently a party to any legal proceedings that we believe would reasonably be expected to have a materially adverse effect on our business, financial condition or results of operations. Concentration of Risk We are subject to credit risk with respect to our tenant receivables and deferred rent receivables related to our tenant leases. Our tenants' ability to honor the terms of their respective leases remains dependent upon the economic, regulatory and social factors. We seek to minimize our credit risk from our tenant leases by (i) targeting smaller, more affluent tenants, from a diverse mix of industries, (ii) performing credit evaluations of prospective tenants and (iii) obtaining security deposits or letters of credit from our tenants. In 2016 , 2015 and 2014 , no tenant accounted for more than 10% of our total revenues. See Note 2 for the details of our allowances for tenant receivables and deferred rent receivables. All of our properties, including our consolidated JVs and unconsolidated Funds properties, are located in Los Angeles County, California and Honolulu, Hawaii, and we are therefore susceptible to adverse economic and regulatory developments, as well as natural disasters, in those markets. We are also subject to credit risk with respect to our interest rate swap counterparties that we use to manage the risk associated with our floating rate debt. We do not post or receive collateral with respect to our swap transactions. See Note 9 for the details of our interest rate swaps. We seek to minimize our credit risk by entering into agreements with a variety of high quality counterparties with investment grade ratings. We have significant cash balances invested in a variety of short-term money market funds that are intended to preserve principal value and maintain a high degree of liquidity while providing current income. These investments are not insured against loss of principal and there is no guarantee that our investments in these funds will be redeemable at par value. We also have significant cash balances in bank accounts with high quality financial institutions with investment grade ratings. Interest bearing bank accounts at each U.S. banking institution are insured by the FDIC up to $250 thousand . Asset Retirement Obligations Conditional asset retirement obligations represent a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement is conditional on a future event that may or may not be within our control. A liability for a conditional asset retirement obligation must be recorded if the fair value of the obligation can be reasonably estimated. Environmental site assessments and investigations have identified twenty-five buildings in our Consolidated Portfolio, and four buildings owned by our unconsolidated Funds which contain asbestos, and would have to be removed in compliance with applicable environmental regulations if these properties are demolished or undergo major renovations. As of December 31, 2016 , the obligations to remove the asbestos from these properties have indeterminable settlement dates, and we are unable to reasonably estimate the fair value of the associated conditional asset retirement obligation. Development Contracts During the first quarter of 2016, we commenced building an additional 475 apartments (net of existing apartments removed) at our Moanalua Hillside Apartments in Honolulu, Hawaii. The $120.0 million estimated cost of the new apartments does not include the cost of the land which we already owned before beginning the project. We also plan to invest additional capital to upgrade the existing apartments, improve the parking and landscaping, build a new leasing and management office, and construct a new recreation and fitness facility with a new pool. As of December 31, 2016 , we had a remaining commitment for contracts related to the development of $107.0 million . Other Contracts As of December 31, 2016 , we had a remaining commitment for capital expenditure projects and repositionings of approximately $3.6 million . Guarantees We made certain environmental and other limited indemnities and guarantees covering customary non-recourse carve- outs for our unconsolidated Funds' debt. We also guaranteed the related swaps. Our Funds have agreed to indemnify us for any amounts that we would be required to pay under these agreements. As of December 31, 2016 , all of the obligations under the related debt and swap agreements have been performed in accordance with the terms of those agreements. The table below summarizes our Funds' debt as of December 31, 2016 , the amounts represent 100% (not our pro-rata share) of amounts related to our Funds: Fund (1) Principal Balance (in millions) Loan Maturity Date Variable Interest Rate Swap Maturity Date Swap Fixed Interest Rate Fund X (2) $ 325.0 5/1/2018 LIBOR + 1.75% 5/1/2017 2.35% Partnership X (3) 110.0 3/1/2023 LIBOR + 1.40% 3/1/2021 2.30% $ 435.0 ___________________________________________________ (1) See Note 5 for more information regarding our unconsolidated Funds. (2) Floating rate term loan, swapped to fixed, which is secured by six properties and requires monthly payments of interest only, with the outstanding principal due upon maturity. As of December 31, 2016 , assuming a zero-percent LIBOR interest rate during the remaining life of the swap, the maximum future payments under the swap agreement were $0.7 million . (3) Floating rate term loan, swapped to fixed, which is secured by two properties and requires monthly payments of interest only, with the outstanding principal due upon maturity. As of December 31, 2016 , assuming a zero-percent LIBOR interest rate during the remaining life of the swap, the maximum future payments under the swap agreement were $4.2 million .

Summary of Significant Accounting Policies (Policy)	12 Months Ended

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.
Investment in Real Estate	Investment in Real Estate We account for acquisitions of properties as business combinations using the purchase method, and include the results of operations of the acquired properties in our results of operations from their respective dates of acquisition. We expense transaction costs related to acquisitions when they are incurred. We estimate the purchase price allocation of acquired properties, which is based upon our estimates of future cash flows and other valuation techniques, to allocate the purchase price among: (i) land, (ii) buildings and improvements, (iii) tenant improvements and identifiable intangible assets such as in-place at-market leases, and (iv) acquired above- and below-market ground and tenant leases (including for renewal options). We estimate the fair values of the tangible assets on an ‘‘as-if-vacant’’ basis. The estimated fair value of acquired in-place at-market leases are the estimated costs to lease the property to the occupancy level at the date of acquisition, including the fair value of leasing commissions and legal costs. We evaluate the time period over which we expect such occupancy level to be achieved and include an estimate of the net operating costs (primarily real estate taxes, insurance and utilities) incurred during the lease-up period. Above- and below-market ground and tenant leases are recorded as an asset or liability based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between the contractual amounts to be paid or received pursuant to the in-place ground or tenant leases, respectively, and our estimate of fair market rental rates for the corresponding in-place leases, over the remaining non-cancelable term of the lease. Our initial valuations and allocations are subject to change until the allocation is finalized within 12 months after the acquisition date. See Note 3 for our property acquisition disclosures. Buildings and improvements are depreciated on a straight-line basis using an estimated life of forty years for buildings and fifteen years for improvements, and are carried on our balance sheet, offset by the related accumulated depreciation and any impairment charges, until they are sold. Tenant improvements are depreciated on a straight-line basis over the life of the related lease, with any remaining balance depreciated in the period of any early termination of that lease. Acquired in-place leases are amortized on a straight line basis over the weighted average remaining term of the acquired in-place leases, and are carried on our balance sheet, offset by the related accumulated amortization, until the related building is either sold or impaired. Leasing intangibles are amortized on a straight-line basis over the related lease term, with any remaining balance amortized in the period of any early termination of that lease. Acquired above- and below-market tenant leases are amortized/accreted on a straight line basis over the life of the related lease and recorded as either an increase (for below-market leases) or a decrease (for above-market leases) to rental revenue. Acquired above- and below-market ground leases, from which we earn ground rent income, are amortized/accreted on a straight line basis over the life of the related lease and recorded either as an increase (for below-market leases) or a decrease (for above-market leases) to rental revenue. Acquired above- and below-market ground leases, for which we incur ground rent expense, are accreted/ amortized over the life of the related lease and recorded either as an increase (for below-market leases) or a decrease (for above-market leases) to expense. When assets are sold or retired, their cost and related accumulated depreciation or amortization are removed from our balance sheet with the resulting gains or losses, if any, reflected in our results of operations for the respective period. Repairs and maintenance are recorded as expense when incurred. Properties are classified as held for sale in the consolidated balance sheets when they meet certain requirements, including the approval of the sale of the property, the marketing of the property for sale, and our expectation that the sale will likely occur within the next 12 months. Properties classified as held for sale are carried at the lower of their carrying value or fair value less costs to sell, and we also cease to depreciate the property. Costs incurred during the period of construction of real estate are capitalized. Cost capitalization of development and redevelopment activities begins during the predevelopment period, which we define as the activities that are necessary to begin the development of the property. We cease capitalization upon substantial completion of the project, but no later than one year from cessation of major construction activity. We also cease capitalization when activities necessary to prepare the property for its intended use have been suspended. Capitalized costs are included in Property under development in our Consolidated Balance Sheets. Once major construction activity has ceased and the development or redevelopment property is in the lease-up phase, the capitalized costs are transferred to (i) Land, (ii) Building and improvements and (iii) Tenant improvements and lease intangibles on our Consolidated Balance Sheets as the historical cost of the property.
Investment in Unconsolidated Real Estate Funds	Investment in Unconsolidated Real Estate Funds We manage and hold equity interests in two Funds: Fund X and Partnership X. As of December 31, 2016 , we held a 68.61% interest in Fund X and 24.25% interest in Partnership X. We account for our investments in the Funds using the equity method because we have significant influence but not control over the Funds, and our Funds do not qualify as VIEs. Our investment balance includes our share of the net assets of the combined Funds, acquisition basis difference, additional basis for capital raising costs, our share of our Funds' accumulated other comprehensive income (loss) related to our Funds' derivatives, and notes receivable from our Funds.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets We periodically assess whether there has been any impairment in the carrying value of our properties whenever events or changes in circumstances indicate that the carrying value of a property may not be recoverable. An impairment charge is recorded when events or change in circumstances indicate that a decline in the fair value below the carrying value has occurred and such decline is other-than-temporary. Recoverability of the carrying value of our properties is measured by a comparison of the carrying value to the undiscounted future cash flows expected to be generated by the property. If the carrying value exceeds the estimated undiscounted future cash flows, an impairment loss is recorded equal to the difference between the properties carrying value and its fair value based on the estimated discounted future cash flows. We also perform a similar periodic assessment for our investments in our Funds.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider short-term investments with maturities of three months or less when purchased to be cash equivalents.
Revenue and Gain Recognition	Revenue and Gain Recognition We recognize revenue when four basic criteria are met: (i) persuasive evidence of an arrangement exists, (ii) services are rendered, (iii) the fee is fixed and determinable and (iv) collectibility is reasonably assured. All of our tenant leases are classified as operating leases. For all lease terms exceeding one year, rental income is recognized on a straight-line basis over the term of the lease. Deferred rent receivables represent rental revenue recognized on a straight-line basis in excess of billed rents. Rental revenue from month-to-month leases or leases with no scheduled rent increases or other adjustments are recognized on a monthly basis when earned. Lease termination fees, which are included in rental revenues in the consolidated statements of operations, are recognized when the related lease is canceled and we have no continuing obligation to provide services to the former tenant. We recognized lease termination revenue of $2.4 million , $2.2 million , $2.6 million during 2016 , 2015 and 2014 , respectively. Tenant improvements constructed by us and reimbursed by tenants are recorded as our assets, and the related revenue, which is included in rental revenues in the consolidated statements of operations, is recognized over the related lease term. We recognized revenue for leasehold improvements of $2.6 million , $1.9 million , $1.7 million during 2016 , 2015 and 2014 , respectively. Estimated tenant recoveries for real estate taxes, common area maintenance and other recoverable operating expenses are recognized as revenue on a gross basis in the period that the recoverable expenses are incurred. Subsequent to year-end, we perform reconciliations on a lease-by-lease basis and bill or credit each tenant for any cumulative annual adjustments. Recognition of gains on sales of investments in real estate requires that we measure the timing of a sale against various criteria related to the terms of the transaction, as well as any continuing involvement in the form of management or financial assistance associated with the property. If the sales criteria are not met, we defer gain recognition and account for the continued operations of the property by applying the finance, profit-sharing or leasing method. If the sales criteria have been met, we further analyze whether profit recognition is appropriate using the full accrual method. If the criteria to recognize profit using the full accrual method have not been met, we defer the gain and recognize it when the criteria are met or use the installment or cost recovery method as appropriate under the circumstances.
Allowances for Tenant Receivables and Deferred Rent Receivables	Allowances for Tenant Receivables and Deferred Rent Receivables We carry tenant receivables and deferred rent receivables net of allowances. Tenant receivables consist primarily of amounts due for contractual lease payments and reimbursements of common area maintenance expenses, property taxes, and other costs recoverable from tenants. Deferred rent receivables represent the amount by which the cumulative straight-line rental revenue recorded to date exceeds cash rents billed to date under the lease agreement. We consider many factors when evaluating the level of reserves necessary, including evaluations of individual tenant receivables, historical loss activity, current economic conditions and other relevant factors.
Insurance Recoveries	Insurance Recoveries Insurance recoveries related to property damage are recorded as other income when payment is either received or receipt is determined to be probable.
Interest Income	Interest Income Interest income on our notes receivable is recognized over the life of the respective notes using the effective interest method and recognized on the accrual basis. Interest income is included in other income in the consolidated statements of operations.
Loan Costs	Loan Costs Loan costs incurred directly with the issuance of secured notes payable and revolving credit facilities are deferred and amortized to interest expense over the respective loan or credit facility term. Any unamortized amounts are written off upon early repayment of the secured notes payable, and the related cost and accumulated amortization are removed from our balance sheet. To the extent that a refinancing is considered an exchange of debt with the same lender, we account for loan costs based upon whether the old debt is determined to be modified or extinguished for accounting purposes. If the old debt is determined to be modified then we (i) continue to defer and amortize any unamortized deferred loan costs associated with the old debt at the time of the modification over the new term of the modified debt, (ii) defer and amortize the lender costs incurred in connection with the modification over the new term of the modified debt, and (iii) expense all other costs associated with the modification. If the old debt is determined to be extinguished then we (i) write off any unamortized deferred loan costs associated with the extinguished debt at the time of the extinguishment and remove the related cost and accumulated amortization from our balance sheet, (ii) expense all lender costs associated with the extinguishment, and (iii) defer and amortize all other costs incurred directly in connection with the extinguishment over the term of the new debt. In circumstances where we modify or exchange our revolving credit facility with the same lender, we account for the loan costs based upon whether the borrowing capacity (defined as the product of the remaining term and the maximum available credit) of the new arrangement is (a) greater than or equal to the borrowing capacity of the old arrangement, or (b) less than the borrowing capacity of the old arrangement. If the borrowing capacity of the new arrangement is greater than or equal to the borrowing capacity of the old arrangement, then we (i) continue to defer and amortize the unamortized deferred loan costs from the old arrangement over the term of the new arrangement and (ii) defer all lender and other costs incurred directly in connection with the new arrangement over the term of the new arrangement. If the borrowing capacity of the new arrangement is less than the borrowing capacity of the old arrangement, then we (i) amortize any unamortized deferred loan costs at the time of the change related to the old arrangement in proportion to the decrease in the borrowing capacity of the old arrangement and (ii) defer all lender and other costs incurred directly in connection with the new arrangement over the term of the new arrangement. Deferred loan costs are presented in the balance sheet as a direct deduction from the carrying amount of our secured notes payable and revolving credit facility. All loan costs expensed and deferred loan costs amortized are included in interest expense in our consolidated statements of operations.
Derivative Contracts	Derivative Contracts We make use of interest rate swap and interest rate cap contracts to manage the risk associated with changes in interest rates on our floating-rate debt. When we enter into a floating-rate term loan, we generally enter into an interest rate swap agreement for the equivalent principal amount, for a period covering the majority of the loan term, which effectively converts our floating-rate debt to a fixed-rate basis during that time. In limited instances, we make use of interest rate caps to limit our exposure to interest rate increases on our floating-rate debt. We do not speculate in derivatives and we do not make use of any other derivative instruments. When we enter into derivative agreements, we generally elect to designate them as cash flow hedges for accounting purposes. Changes in fair value of hedging instruments designated as cash flow hedges are recorded in accumulated other comprehensive income (loss) (AOCI), which is a component of equity outside of earnings, and any hedge ineffectiveness is recorded as interest expense. For our Funds' hedging instruments designated as cash flow hedges, we record our share of the changes in fair value of the hedging instrument in AOCI and our share of any hedge ineffectiveness is recorded in income, including depreciation, from unconsolidated real estate funds in our consolidated statements of operations. Amounts recorded in AOCI related to our designated hedges are reclassified to interest expense as interest payments are made on the hedged floating rate debt. Amounts reported in AOCI related to our Funds' hedges are reclassified to income, including depreciation, from unconsolidated real estate funds, as interest payments are made by our Funds on their hedged floating rate debt. Changes in fair value of hedging instruments not designated as cash flow hedges are recorded as interest expense. We present our derivatives on the balance sheet at fair value on a gross basis. Our share of the fair value of our Funds' derivatives is included in our investment in unconsolidated real estate funds on our consolidated balance sheet.
Stock-Based Compensation	Stock-Based Compensation We account for stock-based compensation, including stock options and LTIP Units, using the fair value method of accounting. The estimated fair value of stock options and LTIP Units is amortized over any vesting period.
EPS	EPS We calculate basic EPS by dividing the net income attributable to common stockholders for the period by the weighted average number of common shares outstanding during the period. We calculate diluted EPS by dividing the net income attributable to common stockholders for the period by the weighted average number of common shares and dilutive instruments outstanding during the period using the treasury stock method. Unvested LTIP Units contain nonforfeitable rights to dividends and we account for them as participating securities and include them in the computation of basic and diluted EPS using the two-class method.
Segment Information	Segment Information Segment information is prepared on the same basis that our management reviews information for operational decision-making purposes. We operate two business segments: the acquisition, development, ownership and management of office real estate, and the acquisition, development, ownership and management of multifamily real estate. The services for our office segment include primarily rental of office space and other tenant services, including parking and storage space rental. The services for our multifamily segment include primarily rental of apartments and other tenant services, including parking and storage space rental.
Income Taxes	Income Taxes We have elected to be taxed as a REIT under the Code, commencing with our initial taxable year ended December 31, 2006. To qualify as a REIT, we are required (among other things) to distribute at least 90% of our REIT taxable income to our stockholders and meet various other requirements imposed by the Code relating to matters such as operating results, asset holdings, distribution levels and diversity of stock ownership. Provided that we qualify for taxation as a REIT, we are generally not subject to corporate-level income tax on the earnings distributed currently to our stockholders that we derive from our REIT qualifying activities. If we fail to qualify as a REIT in any taxable year, and are unable to avail ourselves of certain savings provisions set forth in the Code, all of our taxable income would be subject to federal income tax at regular corporate rates, including any applicable alternative minimum tax. We have elected to treat two of our subsidiaries as TRS, which generally may engage in any business, including the provision of customary or non-customary services to our tenants. A TRS is treated as a regular corporation and is subject to federal income tax and applicable state income and franchise taxes at regular corporate rates. Neither of our TRS had any significant tax provisions or deferred income tax items for 2016 , 2015 or 2014 . Our subsidiaries (other than our TRS), including our Operating Partnership, are partnerships, disregarded entities, QRS or REITs, as applicable, for federal income tax purposes. Under applicable federal and state income tax rules, the allocated share of net income or loss from disregarded entities or flow-through entities is reportable in the income tax returns of the respective owners. Accordingly, no income tax provision is included in our consolidated financial statements.
New Accounting Pronouncements	New Accounting Pronouncements Changes to GAAP are established by the FASB in the form of ASUs. We consider the applicability and impact of all ASUs. Recently Issued and Adopted Accounting Pronouncements In January 2015, the FASB issued ASU No. 2015-01, "Income Statement—Extraordinary and Unusual Items (Subtopic 225-20)", which eliminates the concept of extraordinary items from GAAP. The FASB issued this ASU as part of its initiative to reduce complexity in accounting standards (the Simplification Initiative). The objective of the Simplification Initiative is to identify, evaluate, and improve areas of GAAP for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided to the users of financial statements. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, which for us was the first quarter of 2016. We adopted the ASU in the first quarter of 2016 and it did not have a material impact on our financial position, results of operations or disclosures. In February 2015, the FASB issued ASU No. 2015-02, "Amendments to the Consolidation Analysis (Consolidation - Topic 810)", which provides guidance regarding the consolidation of certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, which for us was the first quarter of 2016. We adopted the ASU in the first quarter of 2016 and it did not have a material impact on our financial position, results of operations or disclosures. In September 2015, the FASB issued ASU No. 2015-16, "Simplifying the Accounting for Measurement-Period Adjustments", which amends "Business Combinations" (Topic 805). The ASU requires that an acquirer (i) recognize adjustments to provisional amounts from business combinations that are identified during the measurement period in the reporting period in which the adjustment amounts are determined, (ii) record, in the same period’s financial statements, the effect on earnings, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date and (iii) disclosure of the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, which for us was the first quarter of 2016. We adopted the ASU in the first quarter of 2016 and it did not have a material impact on our financial position, results of operations or disclosures. In March 2016, the FASB issued ASU No. 2016-05, "Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships", which amends "Derivatives and Hedging" (Topic 815). The ASU provides guidance on the effect of derivative contract novations on existing hedge accounting relationships. The ASU clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under Topic 815, does not in and of itself require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. The ASU is effective for fiscal years beginning after December 15, 2016, and interim periods within those years, which for us would be the first quarter of 2017, and early adoption is permitted. We adopted the ASU in the first quarter of 2016 and it did not have a material impact on our financial position, results of operations or disclosures. Recently Issued Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, "Leases" (Topic 842). The main difference between previous GAAP and Topic 842 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under prevailing GAAP. The accounting applied by a lessor is largely unchanged from that applied under prevailing GAAP. For example, the vast majority of operating leases will remain classified as operating leases, and lessors will continue to recognize lease income for those leases on a straight-line basis over the lease term. Topic 842 requires an entity to separate the lease components from the non-lease components (for example, maintenance services or other activities that transfer a good or service to the customer) in a contract. Only the lease components must be accounted for in accordance with Topic 842. The consideration in the contract is allocated to the lease and non-lease components on a relative standalone price basis (for lessees) or in accordance with the allocation guidance in Topic 606 (for lessors). Topic 842 defines capitalizable initial direct costs of a lease as costs that would not have been incurred had the lease not been obtained. Costs to negotiate or arrange a lease that would have been incurred regardless of whether the lease was obtained, such as fixed employee salaries, are not initial direct costs, and may not be capitalized. The ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those years, which for us would be the first quarter of 2019, and early adoption is permitted. In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers" (Topic 606), which provides guidance for the accounting of revenue from contracts with customers. The guidance supersedes the revenue recognition requirements in Topic 605, "Revenue Recognition", and most industry-specific guidance throughout the Industry Topics of the Codification. In March 2016, the FASB issued ASU No. 2016-08, "Principal versus Agent Considerations (Reporting Revenue Gross versus Net)" which amends "Revenue from Contracts with Customers" (Topic 606). The ASU clarifies the guidance for principal versus agent considerations. In April 2016, the FASB issued ASU No. 2016-10, "Identifying Performance Obligations and Licensing" which amends "Revenue from Contracts with Customers" (Topic 606). The ASU provides guidance for identifying performance obligations and licensing. In May 2016, the FASB issued ASU No. 2016-12, "Narrow-Scope Improvements and Practical Expedients" which amends "Revenue from Contracts with Customers" (Topic 606). The ASU provides guidance for a variety of revenue recognition related topics. In August 2015, the FASB issued ASU No. 2015-14, which defers the effective date of ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) by one year. As a result, the various ASUs listed above are now effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, which for us is the first quarter of 2018. Earlier application is permitted for fiscal years beginning after December 15, 2016, including interim reporting periods within those years, which for us is the first quarter of 2017. The amendments in this ASU should be applied retrospectively. We are not planning on early adopting the ASU and we expect to use the modified retrospective method of adoption. We are currently evaluating the potential impact to our accounting, particularly with respect to our tenant recovery revenues, and whether such changes will be material to our future results of operations and financial position. As noted above, ASU 2016-02 "Leases" requires that non-lease components such as tenant recovery revenues be accounted for in accordance with ASU 2014-09, which means that the classification and timing of our tenant recovery revenues could be impacted. In June 2016, the FASB issued ASU No. 2016-13, "Measurement of Credit Losses on Financial Instruments" which amends "Financial Instruments-Credit Losses" (Topic 326). The ASU provides guidance for measuring credit losses on financial instruments. The ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those years, which for us would be the first quarter of 2020, and early adoption is permitted commencing the first quarter of 2019. The amendments in this ASU should be applied retrospectively. We are currently evaluating the impact of this ASU. In August 2016, the FASB issued ASU No. 2016-15, "Classification of Certain Cash Receipts and Cash Payments" which amends "Statement of Cash Flows" (Topic 230). The ASU provides guidance regarding the presentation of certain types of transactions in the statement of cash flows. The ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those years, which for us would be the first quarter of 2018, and early adoption is permitted. The amendments in this ASU should be applied retrospectively. We do not expect the ASU to have a material impact on our statement of cash flows. In October 2016, the FASB issued ASU No. 2016-17, "Interests Held Through Related Parties That Are Under Common Control". The ASU provides guidance regarding consolidation of VIE's. The ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within those years, which for us would be the first quarter of 2017. The amendments in this ASU should be applied retrospectively. We do not expect the ASU to have a material impact on our financial position, results of operations or disclosures. In November 2016, the FASB issued ASU No. 2016-18, "Restricted Cash". The ASU provides guidance regarding the presentation of restricted cash in the statement of cash flows. The ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those years, which for us would be the first quarter of 2018. The amendments in this ASU should be applied retrospectively. We do not expect the ASU to have a material impact on our statement of cash flows. In January 2017, the FASB issued ASU No. 2017-01, "Clarifying the Definition of a Business". The ASU provides guidance regarding the definition of a business with the objective of providing guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those years, which for us would be the first quarter of 2018. The ASU should be applied prospectively and early adoption is permitted. The ASU will impact our future results of operations and cash flows because we expect that our property acquisitions will be accounted for as asset purchases, and the related acquisition expenses capitalized as part of the respective asset. We historically accounted for our property acquisitions as business acquisitions and expensed the related acquisition expenses as incurred. We are currently evaluating the impact of this ASU. The FASB has not issued any other ASUs during 2016 and 2017 that we expect to be applicable and have a material impact on our future financial position, results of operations, cash flows or disclosures.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Our estimates of the fair value of financial instruments were determined using available market information and widely used valuation methods. Considerable judgment is necessary to interpret market data and determine an estimated fair value. The use of different market assumptions or valuation methods may have a material effect on the estimated fair values. The FASB fair value framework hierarchy distinguishes between assumptions based on market data obtained from sources independent of the reporting entity, and the reporting entity’s own assumptions about market-based inputs. The hierarchy is as follows: Level 1 - inputs utilize unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 - inputs are observable either directly or indirectly for similar assets and liabilities in active markets. Level 3 - inputs are unobservable assumptions generated by the reporting entity
