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. Through our interest in our Operating Partnership and its subsidiaries, consolidated JVs and unconsolidated Funds, we focus on owning, acquiring, developing and managing a significant market 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. The terms "us," "we" and "our" as used in the financial statements refer to Douglas Emmett, Inc. and its subsidiaries on a consolidated basis. At June 30, 2019 , our Consolidated Portfolio consisted of (i) a 16.6 million square foot office portfolio, (ii) 4,069 multifamily apartment units and (iii) fee interests in two parcels of land from which we receive rent under ground leases. We also manage and own equity interests in unconsolidated Funds which, at June 30, 2019 , owned an additional 1.8 million square feet of office space. We manage our unconsolidated Funds alongside our Consolidated Portfolio, and we therefore present the statistics for our office portfolio on a Total Portfolio basis. As of June 30, 2019 , our portfolio (not including two parcels of land from which we receive rent under ground leases), consisted of the following properties (both of which include ancillary retail space): Consolidated Portfolio Total Portfolio Office Wholly-owned properties 53 53 Consolidated JV properties 11 11 Unconsolidated Fund properties — 8 64 72 Multifamily Wholly-owned properties 10 10 Consolidated JV properties 1 1 11 11 Total 75 83 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 of which we are the primary beneficiary. As of June 30, 2019 , the total consolidated assets, liabilities and equity of the VIEs was $8.68 billion (of which $8.09 billion related to investment in real estate), $4.63 billion and $4.05 billion (of which $1.56 billion related to noncontrolling interests), respectively. We report our office rental revenues and tenant recoveries on a combined basis as Rental revenues and tenant recoveries under Office rental in our consolidated statements of operations, and we reclassified the comparable periods to conform to the current period presentation. The accompanying unaudited interim financial statements have been prepared pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in the financial statements prepared in conformity with US GAAP may have been condensed or omitted pursuant to SEC rules and regulations, although we believe that the disclosures are adequate to make their presentation not misleading. The accompanying unaudited interim financial statements include, in our opinion, all adjustments, consisting of normal recurring adjustments, necessary to present fairly the financial information set forth therein. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 . The interim financial statements should be read in conjunction with the consolidated financial statements in our 2018

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies On January 1, 2019, we adopted ASUs that changed our accounting policy for leases. See "New Accounting Pronouncements" below. We have not made any other changes to our significant accounting policies disclosed in our 2018 Annual Report on Form 10-K. Use of Estimates The preparation of financial statements in conformity with US 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. Revenue Recognition Office parking revenues, which are included in Parking and other income under Office rental in our consolidated statements of operations, are within the scope of Topic 606 (Revenue from Contracts with Customers). Our lease contracts generally make a specified number of parking spaces available to the tenant, and we bill and recognize parking revenues on a monthly basis in accordance with the lease agreements, generally using the monthly parking rates in effect at the time of billing. Office parking revenues were $26.9 million and $25.7 million for the three months ended June 30, 2019 and 2018 , and $53.3 million and $50.8 million for the six months ended June 30, 2019 and 2018 , respectively. Office parking receivables were $1.1 million as of June 30, 2019 and December 31, 2018 , and are included in Tenant receivables in our consolidated balance sheets. Income Taxes We have elected to be taxed as a REIT under the Code. 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. We are subject to corporate-level tax on the earnings that we derive through our TRS. New Accounting Pronouncements Changes to US GAAP are implemented by the FASB in the form of ASUs. We consider the applicability and impact of all ASUs. Other than the ASUs discussed below, the FASB has not issued any other ASUs that we expect to be applicable and have a material impact on our financial statements. ASUs Adopted ASU 2016-02 (Topic 842 - "Leases") In February 2016, the FASB issued ASU No. 2016-02, (Topic 842 - "Leases"). The primary impact of the ASU is the recognition of lease assets and liabilities on the balance sheet by lessees for leases classified as operating leases. The accounting applied by lessors is largely unchanged. For example, the vast majority of operating leases remain classified as operating leases, and lessors continue to recognize lease payments for those leases on a straight-line basis over the lease term. We adopted the ASU on January 1, 2019 using the modified retrospective transition method. We recorded cumulative adjustments of $2.1 million and $0.4 million to the opening balances of accumulated deficit and noncontrolling interests, respectively, for leasing expenses related to leases that were entered into before the adoption date but commenced after the adoption date. The ASU provides a practical expedient package, which we elected to use, that allows entities (a) not to reassess whether any expired or existing contracts as of the adoption date are considered or contain leases; (b) not to reassess the lease classification for any expired or existing leases as of the adoption date; and (c) not to reassess initial direct costs for any existing leases as of the adoption date. All leases entered into on or after the adoption date were accounted for under the ASU. We lease space to tenants at our office and multifamily properties. Under the ASU, all of our tenant leases continue to be classified as operating leases. The ASU continues to require that lease payments for operating leases be recognized over the lease term on a straight-line basis unless another systematic and rational basis is more representative of the pattern in which benefit is expected to be derived from the use of the underlying asset. If collectibility of the lease payments is not probable at the commencement date, then the lease income should be limited to the lesser of the income recognized on a straight-line basis or cash basis. If the assessment of collectibility changes after the commencement date, any difference between the lease income that would have been recognized on a straight-line basis and cash basis must be recognized as a current-period adjustment to lease income. The ASU requires separation of the lease 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 are accounted for in accordance with the ASU. The consideration in the contract is allocated to the lease and non-lease components on a relative standalone selling price basis and the non-lease component would be accounted for in accordance with ASC 606 ("Revenue from Contracts with Customers"). In July 2018, the FASB issued ASU No. 2018-11 which includes an optional practical expedient for lessors to elect, by class of underlying asset, to not separate the lease from the non-lease components if certain criteria are met. Our office tenant leases include a lease component for the rental income and a non-lease component for the related tenant recoveries. We determined that our office tenant leases qualify for the single component presentation and we adopted the practical expedient. We account for the combined components under the ASU. Rental revenues and tenant recoveries from our office tenant leases is included in Rental revenues and tenant recoveries under Office rental in our consolidated statements of operations. Rental revenues from our multifamily tenant leases is included in multifamily Rental revenues in our consolidated statements of operations. Rental revenue recognized on a straight-line basis in excess of billed rents is included in Deferred rent receivables in our consolidated balance sheets. See Note 15 for more information regarding the future lease rental receipts from our operating leases. The ASU defines initial direct costs of a lease, which may be capitalized, as costs that would not have been incurred had the lease not been executed. Costs to negotiate a lease that would have been incurred regardless of whether the lease was executed, such as employee salaries, are not considered to be initial direct costs, and may not be capitalized. We historically capitalized most of our leasing costs. We expensed $1.1 million and $2.1 million during the three and six months ended June 30, 2019 , respectively, of leasing costs related to our tenant leases that did not qualify as initial direct costs of a lease, which are included in General and administrative expenses in our consolidated statements of operations. We pay rent under a ground lease which expires on December 31, 2086 . Upon adoption of the ASU, we continued to classify the lease as an operating lease, and we recognized a right-of-use asset for the land and a lease liability for the future lease payments of $10.9 million . We calculated the carrying value of the right-of-use asset and lease liability by discounting the future lease payments using our incremental borrowing rate. We adjusted the right-of-use asset carrying value for a related above-market ground lease liability of $3.4 million , which reduced the carrying value of the asset to $7.5 million . We continued to recognize the lease payments as expense, which is included in Office expenses in our Consolidated Statements of Operations. See Note 4 for more information regarding this ground lease. See Note 13 for the fair value disclosures related to the ground lease liability. In December 2018, the FASB issued ASU 2018-20, an update to ASU 2016-02, which provides guidance on accounting for sales and other similar taxes collected from lessees, certain lessor costs, and recognition of variable payments for contracts with lease and nonlease components. We adopted the ASU and it did not have a material impact on our financial statements. In March 2019, the FASB issued ASU 2019-01, an update to ASU 2016-02, which provides guidance on transition disclosures related to Topic 250 "Accounting Changes and Error Corrections" and other technical updates. We adopted the ASU and it did not have a material impact on our financial statements.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Contracts	Derivative Contracts We make use of interest rate swap and 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 also 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. See Note 8 regarding our debt, and our consolidated JVs debt, that is hedged. See Note 16 regarding our unconsolidated Funds debt that is hedged. Derivative Summary As of June 30, 2019 , our interest rate swaps, which include the interest rate swaps of our consolidated JVs and our unconsolidated Funds, were designated as cash flow hedges: Number of Interest Rate Swaps Notional (In thousands) Consolidated derivatives (1)(2)(4) 36 $ 4,484,800 Unconsolidated Funds' derivatives (3)(4) 4 $ 510,000 ___________________________________________________ (1) The notional amount reflects 100% , not our pro-rata share, of our consolidated JVs' derivatives.

(4) See Note 13 for our derivative fair value disclosures. Credit-risk-related Contingent Features Our swaps include credit-risk related contingent features, for example, we have agreements with certain of our interest rate swap counterparties that contain a provision under which we could be declared in default on our derivative obligations if repayment of the underlying indebtedness that we are hedging is accelerated by the lender due to our default on the indebtedness. As of June 30, 2019 , there have been no events of default with respect to our interest rate swaps or our consolidated JVs' or unconsolidated Funds' interest rate swaps. We do not post collateral for our interest rate swap contract liabilities. The fair value of our interest rate swap contract liabilities, including accrued interest and excluding credit risk adjustments, were as follows: (In thousands) June 30, 2019 December 31, 2018 Consolidated derivatives (1) $ 52,887 $ 1,681 Unconsolidated Funds' derivatives $ 1,949 $ — ___________________________________________________ (1) Includes 100% , not our pro-rata share, of our consolidated JVs' derivatives. Counterparty Credit Risk We are subject to credit risk from the counterparties on our interest rate swap contract assets because we do not receive collateral. We seek to minimize that risk by entering into agreements with a variety of high quality counterparties with investment grade ratings. The fair value of our interest rate swap contract assets, including accrued interest and excluding credit risk adjustments, were as follows: (In thousands) June 30, 2019 December 31, 2018 Consolidated derivatives (1) $ 18,749 $ 76,021 Unconsolidated Funds' derivatives (2) $ 1,598 $ 12,576 ___________________________________________________ (1) The amounts reflect 100% , not our pro-rata share, of our consolidated JVs' derivatives.

Equity	Equity Transactions During the six months ended June 30, 2019 , (i) we acquired 75 thousand OP Units in exchange for issuing an equal number of shares of our common stock to the holders of the OP Units, (ii) we acquired 13 thousand OP Units for $507 thousand in cash, and (iii) we issued 4.9 million shares of our common stock under our ATM program for net proceeds of $201.2 million . We also purchased a property on June 7, 2019 for a contract price of $365.1 million , which we subsequently contributed to one of our consolidated JVs on June 28, 2019. We manage and own a twenty percent capital interest in the JV. To partially fund the acquisition of the property, we closed a secured, non-recourse $160.0 million interest-only loan scheduled to mature in June 2029, and the loan was assumed by the consolidated JV to which we contributed the property. Noncontrolling interests in the JV contributed $176.0 million to the JV for the acquisition of the property. See Note 3 for more information regarding the property acquisition and Note 8 for more information regarding the loan. During the six months ended June 30, 2018 , we (i) acquired 339 thousand OP Units in exchange for issuing an equal number of shares of our common stock to the holders of the OP Units, (ii) acquired 3 thousand OP Units for $108 thousand in cash and (iii) issued 14 thousand shares of our common stock for the exercise of 32 thousand stock options on a net settlement basis (net of the exercise price and related taxes). 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 June 30, 2019 when we and our Operating Partnership had 175.2 million shares of common stock and 28.1 million OP Units and fully-vested LTIP Units outstanding, respectively. 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 acquire 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 acquisition, 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 employees and non-employee directors as part of their compensation. These awards generally vest over a service period and once vested can generally be converted to OP Units provided our stock price increases by more than a specified hurdle.

(2) We calculate our share by multiplying the total amount for each Fund by our equity interest in the respective Fund. Equity Compensation On June 2, 2016, the Douglas Emmett 2016 Omnibus Stock Incentive Plan ("2016 Plan") became effective after receiving stockholder approval, superseding our prior plan, the Douglas Emmett 2006 Omnibus Stock Incentive Plan ("2006 Plan"), both of which allow for awards to our directors, officers, employees and consultants. The key terms of the two plans are substantially identical, except for the date of expiration, the number of shares authorized for grants and various technical provisions. Grants after June 2, 2016 were awarded under the 2016 Plan, while grants prior to that date were awarded under the 2006 Plan (grants under the 2006 Plan remain outstanding according to their terms). Both plans are administered by the compensation committee of our board of directors. Total net stock-based compensation expense was $2.4 million and $2.9 million for the three months ended June 30, 2019 and 2018 , and $5.0 million and $6.0 million for the six months ended June 30, 2019 and 2018 respectively. These amounts are net of capitalized stock-based compensation of $0.3 million and $0.5 million for the three months ended June 30, 2019 and 2018 , and $1.0 million and $0.9 million for the six months ended June 30, 2019 and 2018 respectively. There were no outstanding options during the six months ended June 30, 2019 . The intrinsic value of options exercised was $0.8 million for the six months ended June 30, 2018

Earnings Per Share [Abstract]
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. We account for unvested LTIP awards that contain nonforfeitable rights to dividends as participating securities and include these securities in the computation of basic and diluted EPS using the two-class method.

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 June 30, 2019 , 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 8 for the details of our secured notes payable. We estimate the fair value of our consolidated secured notes payable 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 the estimated fair value and carrying value of our secured notes payable (excluding our revolving credit facility), the carrying value includes unamortized loan premium and excludes unamortized deferred loan fees: (In thousands) June 30, 2019 December 31, 2018 Fair value $ 4,358,148 $ 4,087,979 Carrying value $ 4,338,627 $ 4,062,968 Ground lease liability: See Note 4 for the details of our ground lease. We estimate the fair value of our ground lease liability by calculating the present value of the future lease payments disclosed in Note 4 using our incremental borrowing rate. The calculation incorporates observable market interest rates which we consider to be Level 2 inputs. The table below presents the estimated fair value and carrying value of our ground lease liability: (In thousands) June 30, 2019 Fair value $ 11,846 Carrying value $ 10,885 Financial instruments measured at fair value Derivative instruments: See Note 10 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 the estimated fair value of our derivatives: (In thousands) June 30, 2019 December 31, 2018 Derivative Assets: Fair value - consolidated derivatives (1) $ 16,788 $ 73,414 Fair value - unconsolidated Funds' derivatives (2) $ 1,465 $ 12,228 Derivative Liabilities: Fair value - consolidated derivatives (1) $ 51,672 $ 1,530 Fair value - unconsolidated Funds' derivatives (2) $ 2,095 $ — ____________________________________________________ (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 sheets. The fair values exclude accrued interest which is included in interest payable in the consolidated balance sheets. (2) Reflects 100% , not our pro-rata share, of our unconsolidated Funds' derivatives. Our pro-rata share of the amounts related to the unconsolidated Funds' derivatives is included in our Investment in unconsolidated real estate funds in our consolidated balance sheets.

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.

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 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. For the six months ended June 30, 2019 and 2018 , no tenant accounted for more than 10% of our total revenues. All of our properties, including the properties of our consolidated JVs and unconsolidated Funds, 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 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 10 for the details of our interest rate contracts. 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 have identified twenty-eight 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 June 30, 2019 , the obligations to remove the asbestos from these properties if they were demolished or undergo major renovations have indeterminable settlement dates, and we are unable to reasonably estimate the fair value of the associated conditional asset retirement obligation. As of June 30, 2019 , the obligations to remove the asbestos from properties that are currently undergoing major renovations, or that we plan to renovate in the future, are not material to our financial statements. Development and Other Contracts In West Los Angeles, we are building a high-rise apartment building with 376 apartments. In downtown Honolulu, we are converting a 25 story, 490,000 square foot office tower into approximately 500 rental apartments. We expect the conversion to occur in phases over a number of years as the office space is vacated. As of June 30, 2019 , we had an aggregate remaining contractual commitment for these and other development projects of approximately $187.4 million . As of June 30, 2019 , we had an aggregate remaining contractual commitment for repositionings, capital expenditure projects and tenant improvements of approximately $32.7 million . Guarantees We have made certain environmental and other limited indemnities and guarantees covering customary non-recourse carve- outs for our unconsolidated Funds' debt. We have 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 June 30, 2019 , 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 June 30, 2019 . The amounts represent 100% (not our pro-rata share) of the amounts related to our Funds: Fund (1) Loan Maturity Date Principal Balance (In Millions) Variable Interest Rate Swap Fixed Interest Rate Swap Maturity Date Partnership X (2)(4) 3/1/2023 $ 110.0 LIBOR + 1.40% 2.30% 3/1/2021 Fund X (3)(4) 7/1/2024 400.0 LIBOR + 1.65% 3.44% 7/1/2022 $ 510.0 ___________________________________________________ (1) See Note 6 for more information regarding our unconsolidated Funds. (2) 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 June 30, 2019 , assuming a zero -percent LIBOR interest rate during the remaining life of the swap, the maximum future payments under the swap agreement were $1.7 million . (3) 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 June 30, 2019 , assuming a zero -percent LIBOR interest rate during the remaining life of the swap, the maximum future payments under the swap agreement were $21.8 million . Loan agreement includes the requirement to purchase an interest rate cap if one-month LIBOR equals or exceeds 3.56% for fourteen consecutive days after the related swap matures. (4) Loan agreement includes a zero-percent LIBOR floor. The corresponding swaps do not include such a floor.

Accounting Policies [Abstract]
Basis of Presentation	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 of which we are the primary beneficiary. As of June 30, 2019 , the total consolidated assets, liabilities and equity of the VIEs was $8.68 billion (of which $8.09 billion related to investment in real estate), $4.63 billion and $4.05 billion (of which $1.56 billion related to noncontrolling interests), respectively. We report our office rental revenues and tenant recoveries on a combined basis as Rental revenues and tenant recoveries under Office rental in our consolidated statements of operations, and we reclassified the comparable periods to conform to the current period presentation. The accompanying unaudited interim financial statements have been prepared pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in the financial statements prepared in conformity with US GAAP may have been condensed or omitted pursuant to SEC rules and regulations, although we believe that the disclosures are adequate to make their presentation not misleading. The accompanying unaudited interim financial statements include, in our opinion, all adjustments, consisting of normal recurring adjustments, necessary to present fairly the financial information set forth therein. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 . The interim financial statements should be read in conjunction with the consolidated financial statements in our 2018 Annual Report on Form 10-K and the notes thereto. Any references to the number or class of properties, square footage, per square footage amounts, apartment units and geography, are outside the scope of our independent registered public accounting firm’s review of our financial statements in accordance with the standards of the PCAOB.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with US 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.
Revenue Recognition	Revenue Recognition
Income Taxes	Income Taxes We have elected to be taxed as a REIT under the Code. 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. We are subject to corporate-level tax on the earnings that we derive through our TRS.
New Accounting Pronouncements	New Accounting Pronouncements Changes to US GAAP are implemented by the FASB in the form of ASUs. We consider the applicability and impact of all ASUs. Other than the ASUs discussed below, the FASB has not issued any other ASUs that we expect to be applicable and have a material impact on our financial statements. ASUs Adopted ASU 2016-02 (Topic 842 - "Leases") In February 2016, the FASB issued ASU No. 2016-02, (Topic 842 - "Leases"). The primary impact of the ASU is the recognition of lease assets and liabilities on the balance sheet by lessees for leases classified as operating leases. The accounting applied by lessors is largely unchanged. For example, the vast majority of operating leases remain classified as operating leases, and lessors continue to recognize lease payments for those leases on a straight-line basis over the lease term. We adopted the ASU on January 1, 2019 using the modified retrospective transition method. We recorded cumulative adjustments of $2.1 million and $0.4 million to the opening balances of accumulated deficit and noncontrolling interests, respectively, for leasing expenses related to leases that were entered into before the adoption date but commenced after the adoption date. The ASU provides a practical expedient package, which we elected to use, that allows entities (a) not to reassess whether any expired or existing contracts as of the adoption date are considered or contain leases; (b) not to reassess the lease classification for any expired or existing leases as of the adoption date; and (c) not to reassess initial direct costs for any existing leases as of the adoption date. All leases entered into on or after the adoption date were accounted for under the ASU. We lease space to tenants at our office and multifamily properties. Under the ASU, all of our tenant leases continue to be classified as operating leases. The ASU continues to require that lease payments for operating leases be recognized over the lease term on a straight-line basis unless another systematic and rational basis is more representative of the pattern in which benefit is expected to be derived from the use of the underlying asset. If collectibility of the lease payments is not probable at the commencement date, then the lease income should be limited to the lesser of the income recognized on a straight-line basis or cash basis. If the assessment of collectibility changes after the commencement date, any difference between the lease income that would have been recognized on a straight-line basis and cash basis must be recognized as a current-period adjustment to lease income. The ASU requires separation of the lease 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 are accounted for in accordance with the ASU. The consideration in the contract is allocated to the lease and non-lease components on a relative standalone selling price basis and the non-lease component would be accounted for in accordance with ASC 606 ("Revenue from Contracts with Customers"). In July 2018, the FASB issued ASU No. 2018-11 which includes an optional practical expedient for lessors to elect, by class of underlying asset, to not separate the lease from the non-lease components if certain criteria are met. Our office tenant leases include a lease component for the rental income and a non-lease component for the related tenant recoveries. We determined that our office tenant leases qualify for the single component presentation and we adopted the practical expedient. We account for the combined components under the ASU. Rental revenues and tenant recoveries from our office tenant leases is included in Rental revenues and tenant recoveries under Office rental in our consolidated statements of operations. Rental revenues from our multifamily tenant leases is included in multifamily Rental revenues in our consolidated statements of operations. Rental revenue recognized on a straight-line basis in excess of billed rents is included in Deferred rent receivables in our consolidated balance sheets. See Note 15 for more information regarding the future lease rental receipts from our operating leases. The ASU defines initial direct costs of a lease, which may be capitalized, as costs that would not have been incurred had the lease not been executed. Costs to negotiate a lease that would have been incurred regardless of whether the lease was executed, such as employee salaries, are not considered to be initial direct costs, and may not be capitalized. We historically capitalized most of our leasing costs. We expensed $1.1 million and $2.1 million during the three and six months ended June 30, 2019 , respectively, of leasing costs related to our tenant leases that did not qualify as initial direct costs of a lease, which are included in General and administrative expenses in our consolidated statements of operations. We pay rent under a ground lease which expires on December 31, 2086 . Upon adoption of the ASU, we continued to classify the lease as an operating lease, and we recognized a right-of-use asset for the land and a lease liability for the future lease payments of $10.9 million . We calculated the carrying value of the right-of-use asset and lease liability by discounting the future lease payments using our incremental borrowing rate. We adjusted the right-of-use asset carrying value for a related above-market ground lease liability of $3.4 million , which reduced the carrying value of the asset to $7.5 million . We continued to recognize the lease payments as expense, which is included in Office expenses in our Consolidated Statements of Operations. See Note 4 for more information regarding this ground lease. See Note 13 for the fair value disclosures related to the ground lease liability. In December 2018, the FASB issued ASU 2018-20, an update to ASU 2016-02, which provides guidance on accounting for sales and other similar taxes collected from lessees, certain lessor costs, and recognition of variable payments for contracts with lease and nonlease components. We adopted the ASU and it did not have a material impact on our financial statements. In March 2019, the FASB issued ASU 2019-01, an update to ASU 2016-02, which provides guidance on transition disclosures related to Topic 250 "Accounting Changes and Error Corrections" and other technical updates. We adopted the ASU and it did not have a material impact on our financial statements.
