Organization and Description of Business [Abstract]
Organization and Description of Business	Organization and Description of Business
	General
	Brookfield DTLA Fund Office Trust Investor Inc. (“Brookfield DTLA” or the “Company”) is a Maryland corporation and was incorporated on April 19, 2013. Brookfield DTLA was formed for the purpose of consummating the transactions contemplated in the Agreement and Plan of Merger dated as of April 24, 2013, as amended (the “Merger Agreement”), and the issuance of shares of 7.625% Series A Cumulative Redeemable Preferred Stock (the “Series A preferred stock”) in connection with the acquisition of MPG Office Trust, Inc. and MPG Office, L.P. (together, “MPG”). Brookfield DTLA is a direct subsidiary of Brookfield DTLA Holdings LLC (“Brookfield DTLA Holdings”), a Delaware limited liability company, and an indirect subsidiary of Brookfield Office Properties Inc. (“BPO”).
	Prior to October 15, 2013, 333 South Hope Co. LLC (“333 South Hope”) and EYP Realty LLC (“EYP Realty”) were controlled by BPO through its indirect ownership interest in TRZ Holdings IV LLC (“TRZ”). TRZ owned 100% of the member units of 333 South Hope and EYP Realty, and BPO indirectly owned approximately 84% of the member units of TRZ.
	On October 15, 2013, through a series of formation transactions, TRZ’s interests in 333 South Hope and EYP Realty were contributed to subsidiaries of Brookfield DTLA in exchange for preferred and common interests in Brookfield DTLA Fund Properties II LLC (“New OP”) and a preferred interest in Brookfield DTLA Fund Properties III LLC (“DTLA OP”). 333 South Hope owned Bank of America Plaza (“BOA Plaza”) and EYP Realty owned Ernst & Young Plaza (“EY Plaza”). Both of these Class A commercial properties are located in the Los Angeles Central Business District (the “LACBD”).
	MPG Acquisition
	On October 15, 2013, Brookfield DTLA completed the acquisition of MPG (the “merger”) pursuant to the terms of the Merger Agreement. As part of the transaction, MPG was contributed to New OP in exchange for a preferred interest in New OP. See Note 3 “Acquisition of MPG Office Trust, Inc.” In addition to BOA Plaza and EY Plaza, Brookfield DTLA now owns Wells Fargo Center–North Tower, Wells Fargo Center–South Tower, Gas Company Tower and 777 Tower, each of which are Class A office properties located in the LACBD that were formerly owned by MPG.
	At the effective time of the merger, (i) each issued and outstanding share of MPG common stock was automatically converted into, and canceled in exchange for, the right to receive $3.15 in cash, without interest and less any required withholding tax and (ii) each issued and outstanding share of 7.625% Series A Cumulative Redeemable Preferred Stock of MPG (the “MPG Preferred Stock”) automatically, and without a vote by the holders of MPG Preferred Stock, was converted into and canceled in exchange for, the right to receive one share of the Company’s Series A preferred stock.
	In connection with the acquisition, DTLA Fund Holding Co., a subsidiary of Brookfield DTLA Holdings, made a tender offer to purchase all of the issued and outstanding shares of MPG Preferred Stock for cash consideration of $25.00 per share (the “offer price”). A total of 372,901 shares of MPG Preferred Stock were validly tendered into the offer and the holders thereof received the offer price for such shares. At the effective time of the merger, each share of MPG Preferred Stock that was issued and outstanding immediately prior to the merger, including each share of MPG Preferred Stock acquired by DTLA Fund Holding Co. in the offer, was exchanged for one share of Series A preferred stock with rights, terms and conditions substantially identical to those of the MPG Preferred Stock.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies
	Predecessor Entities
	Prior to October 15, 2013, Brookfield DTLA had not conducted any business as a separate company and had no material assets or liabilities. In accordance with accounting principles generally accepted in the United States of America (“GAAP”), the contribution of 333 South Hope and EYP Realty (together, the “Predecessor Entities”) constitute a transaction between entities under common control. A combination between entities that already share the same parent is not considered a business combination because there is no change in control at the parent level. Accordingly, the operations of the Predecessor Entities contributed to Brookfield DTLA by TRZ on October 15, 2013 are presented in the accompanying consolidated and combined financial statements as if they were owned by Brookfield DTLA for all historical periods presented and the assets and liabilities of BOA Plaza and EY Plaza were recorded at the carrying values reflected in the books and records of 333 South Hope and EYP Realty. As such, no gain or loss has been recorded in the consolidated statement of operations for the year ended December 31, 2013 due to this transaction. As a result of the transaction, TRZ’s interest in the Predecessor Entities was exchanged for a preferred and common interest in New OP and a preferred interest in DTLA OP. As a result of certain redemption features in the preferred instruments, these instruments have been classified in the consolidated balance sheet as mezzanine equity. See Note 6 “Mezzanine Equity.”
	As used in these consolidated and combined financial statements and related notes, unless the context requires otherwise, the terms “Brookfield DTLA,” the “Company,” “us,” “we” and “our” refer to the combination of Brookfield DTLA Fund Office Trust Investor Inc. and the Predecessor Entities.
	Principles of Consolidation and Combination and Basis of Presentation
	The accompanying consolidated and combined financial statements are prepared in accordance with GAAP. The consolidated balance sheets as of December 31, 2014 and 2013 include the accounts of Brookfield DTLA and subsidiaries in which it has a controlling financial interest. The accompanying consolidated and combined statements of operations for the year ended December 31, 2013 include the accounts of the Predecessor Entities on a combined basis from January 1, 2013 through October 15, 2013 (the date of the merger); and the consolidated accounts of Brookfield DTLA from October 15, 2013 (the date of the merger) through December 31, 2013. The accompanying combined statements of operations
	for the year ended December 31, 2012 include the accounts of the Predecessor Entities on a combined basis. All intercompany transactions have been eliminated in consolidation and combination as of and for the years ended December 31, 2014, 2013 and 2012.
	In determining whether Brookfield DTLA has a controlling financial interest in an entity and the requirement to consolidate the accounts of that entity, management considers factors such as ownership interest, board representation, management representation, authority to make decisions, and contractual and substantive participating rights of the partners/members as well as whether the entity is a variable interest entity (“VIE”) and Brookfield DTLA is the primary beneficiary.
	A VIE is broadly defined as an entity where either (i) the equity investors as a group, if any, lack the power through voting or similar rights to direct the activities of an entity that most significantly impact the entity’s economic performance or (ii) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support.
	A variable interest holder is considered to be the primary beneficiary of a VIE if it has the power to direct the activities of a variable interest entity that most significantly impact the entity’s economic performance and has the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to the VIE. Brookfield DTLA qualitatively assesses whether it is (or is not) the primary beneficiary of a VIE.
	Consideration of various factors includes, but is not limited to, Brookfield DTLA’s ability to direct the activities that most significantly impact the VIE’s economic performance, its form of ownership interest, its representation on the VIE’s governing body, the size and seniority of its investment, its ability and the rights of other investors to participate in policy making decisions and its ability to replace the manager of and/or liquidate the entity.
	The Company earns a return through an indirect investment in New OP. Brookfield DTLA Holdings, the parent of Brookfield DTLA, owns all of the common interest in New OP. Brookfield DTLA has an indirect preferred stock interest in New OP and its wholly owned subsidiary is the managing member of New OP.
	The Company determined that New OP is a VIE and as a result of having the power to direct the significant activities of New OP and exposure to the economic performance of New OP, Brookfield DTLA meets the two conditions for being the primary beneficiary. Brookfield DTLA is required to continually evaluate its VIE relationships and consolidation conclusion.
	Use of Estimates
	The preparation of consolidated and combined financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated and combined financial statements and accompanying notes. For example, estimates and assumptions have been made with respect to fair values of assets and liabilities for purposes of applying the acquisition method of accounting, the useful lives of assets, recoverable amounts of receivables, impairment of long‑lived assets and fair value of debt. Actual results could ultimately differ from such estimates.
	Recent Accounting Pronouncements
	In April 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2014‑08, Presentation of Financial Statements and Property, Plant, and Equipment: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which requires entities to disclose only disposals representing a strategic shift in operations as discontinued operations. The new guidance requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. The new standard is effective in the first quarter of 2015 for public organizations with calendar year-ends. Early adoption is permitted but only for disposals (or classifications as held for sale) that have not been reported in the financial statements previously issued. We do not believe that this update will have a material effect on Brookfield DTLA’s consolidated financial statements in future periods.
	In May 2014, the FASB issued ASU 2014-09 establishing Accounting Standards Codification Topic 606, Revenue from Contracts with Customers. ASU 2014-09 establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most of the existing revenue recognition guidance. ASU 2014-09 requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration that the entity expects to be entitled to receive in exchange for those goods or services and also requires certain additional disclosures. ASU 2014-09 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2016. We are currently evaluating the impact of the adoption of ASU 2014-09 on Brookfield DTLA’s consolidated financial statements.
	In August 2014, the FASB issued ASU 2014-15. Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This topic provides guidance on management’s responsibility to evaluate whether there is substantial doubt about a company’s ability to continue as a going concern and requires related footnote disclosures. The amendments in this ASU are effective for the annual period ending after December 15, 2016, and for annual and interim periods thereafter. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2014-09 on Brookfield DTLA’s consolidated financial statements.
	Significant Accounting Policies
	Business Combinations—
	Purchase accounting is applied to the assets and liabilities related to all real estate investments acquired from third parties. In accordance with FASB Accounting Standards Codification (“ASC”) Topic 805, Business Combinations, the purchase price of the real estate acquired is allocated to the acquired tangible assets, consisting primarily of land, building and tenant improvements, and identifiable intangible assets and liabilities, consisting of the value of above- and below-market leases, in-place leases, and tenant relationships, based in each case on their fair value.
	The principal valuation technique employed by Brookfield DTLA in determining the fair value of identified assets acquired and liabilities assumed is the income approach, which is then compared to the cost approach. Tangible values for investments in real estate are calculated based on replacement costs for like type quality assets. Above- and below-market lease values are determined by comparing in-place rents with current market rents. In‑place lease amounts are determined by calculating the potential lost revenue during the replacement of the current leases in place. Leasing commissions and legal/marketing fees are determined based upon market allowances pro-rated over the remaining lease terms. Mortgage loans assumed in an acquisition are analyzed using current market terms for similar debt.
	The value of the acquired above-market and below-market leases are amortized and recorded as either a decrease (in the case of above-market leases) or an increase (in the case of below-market leases) to rental income in the consolidated and combined statements of operations over the remaining term of the associated lease. The value of tenant relationships is amortized over the expected term of the relationship, which includes an estimated probability of lease renewal. The value of in-place leases is amortized as an expense over the remaining life of the leases. Amortization of tenant relationships and in‑place leases is included in depreciation and amortization in the consolidated and combined statements of operations.
	Investments in Real Estate—
	Land is carried at cost. Buildings are recorded at historical cost and are depreciated on a straight-line basis over the estimated useful life of the building, which is 60 years with an estimated salvage value of 5%. Building improvements are recorded at historical cost and are depreciated on a straight-line basis over their estimated useful lives, which range from 7 years to 13 years. Tenant improvements that are determined to be assets of Brookfield DTLA are recorded at cost; amortization is included in depreciation and amortization expense in the consolidated and combined statements of operations on a straight-line basis over the shorter of the useful life or the applicable lease term.
	Depreciation expense related to investments in real estate during the years ended December 31, 2014, 2013 and 2012 was $67.5 million, $29.1 million and $19.3 million, respectively.
	Real estate is reviewed for impairment if events or changes in circumstances indicate that the carrying amount of the real estate may not be recoverable. In such an event, a comparison is made of the current and projected operating cash flows of the property into the foreseeable future on an undiscounted basis to the carrying amount of the real estate. If the undiscounted cash flows expected to be generated by an asset are less than its carrying amount, an impairment provision would be recorded to write down the carrying amount of such asset to its fair value. Brookfield DTLA assesses fair value based on estimated cash flow projections utilizing appropriate discount and capitalization rates and available market information. Projections of future cash flow take into account the specific business plan for the property and management’s best estimate of the most probable set of economic conditions expected to prevail in the market. Management believes no impairment of Brookfield DTLA’s real estate assets existed at December 31, 2014 and 2013.
	Cash and Cash Equivalents—
	Cash and cash equivalents include all cash and short-term investments with an original maturity of three months or less.
	Restricted Cash—
	Restricted cash consists primarily of deposits for tenant improvements and leasing commissions, real estate taxes and insurance reserves, debt service reserves and other items as required by our loan agreements.
	Rents, Deferred Rents and Other Receivables, Net—
	Differences between rental income and the contractual amounts due are recorded as deferred rents receivable in the consolidated balance sheet. Brookfield DTLA evaluates its deferred rents receivable to consider if an allowance is necessary.
	Rents, deferred rents and other receivables, net also includes any amounts paid to a tenant for improvements owned or costs incurred by the tenant are treated as tenant inducements and are presented in the consolidated balance sheet net of accumulated amortization totaling $3.9 million and $2.7 million as of December 31, 2014 and 2013, respectively. Amortization of tenant inducements is recorded on a straight-line basis over the term of the related lease as a reduction of rental income in the consolidated and combined statements of operations.
	Brookfield DTLA periodically evaluates the collectability of amounts due from tenants and maintains an allowance for doubtful accounts in the consolidated balance sheet for estimated losses resulting from the inability of tenants to make required payments under the lease agreements. Management exercises judgment in establishing these allowances and considers payment history and current credit status in developing these estimates.
	The allowance for doubtful accounts for Brookfield DTLA totaled $0.4 million and $0.4 million as of December 31, 2014 and 2013, respectively. For the years ended December 31, 2014 and 2013, Brookfield DTLA recorded provisions for doubtful accounts of $24 thousand and $0.4 million, respectively. There was no provision for doubtful accounts recorded during the year ended December 31, 2012.
	Due (to) from Affiliates, Net—
	Amounts due to/from affiliates, net consist of related party receivables and payables from affiliates of BPO for advances made primarily for trade purposes. These amounts are due on demand and are non‑interest bearing.
	Brookfield DTLA was indebted to BOP Management Inc. under a $25.0 million promissory note, which was included in due to affiliates, net in the consolidated balance sheet as of December 31, 2013.
	During September 2014, Brookfield DTLA paid $25.8 million in full settlement of the principal and interest outstanding on the intercompany loan using proceeds from the mortgage loan secured by the Figueroa at 7th retail property. See Note 12 “Related Party Transactions.”
	Deferred Charges, Net—
	Leasing costs, primarily commissions related to leasing activities, are deferred and are presented as deferred charges in the consolidated balance sheet net of accumulated amortization totaling $28.3 million and $17.9 million as of December 31, 2014 and 2013, respectively. Deferred leasing costs amortized on a straight-line basis over the terms of the related leases as part of depreciation and amortization in the consolidated and combined statements of operations.
	Prepaid and Other Assets, Net—
	Prepaid and other assets include prepaid insurance, prepaid real estate taxes and other operating costs.
	Mortgage Loans, Net—
	Mortgage loans are presented in the consolidated balance sheet net of unamortized debt discounts totaling $6.9 million and $11.9 million as of December 31, 2014 and 2013, respectively.
	Debt discounts totaling $5.0 million, $0.8 million and $0.6 million were amortized during the years ended December 31, 2014, 2013 and 2012, respectively, over the terms of the related mortgage loans on a basis that approximates the effective interest method and were included as part of interest expense in the consolidated and combined statements of operations.
	Revenue Recognition—
	Rental income from leases providing for periodic increases in base rent is recognized on a straight-line basis over the noncancelable term of the respective leases. Recoveries of operating expenses and real estate taxes are recorded as tenant reimbursements in the consolidated and combined statements of operations in the period during which the expenses are incurred.
	Income Taxes—
	Brookfield DTLA has elected to be taxed as a real estate investment trust (“REIT”) pursuant to Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”), commencing with its tax year ended December 31, 2013. Brookfield DTLA intends to conduct its operations so as to continue to qualify as a REIT. Accordingly, Brookfield DTLA is not subject to U.S. federal income tax, provided that it continues to qualify as a REIT and distributions to its stockholders, if any, generally equal or exceed its taxable income.
	Qualification and taxation as a REIT depends upon Brookfield DTLA’s ability to meet the various qualification tests imposed under the Code related to annual operating results, asset diversification, distribution levels and diversity of stock ownership. Accordingly, no assurance can be given that Brookfield DTLA will be organized or be able to operate in a manner so as to continue to qualify as a REIT. If Brookfield DTLA fails to qualify as a REIT in any taxable year, it will be subject to federal and state income tax on its taxable income at regular corporate tax rates, and it may be ineligible to qualify as a REIT for four subsequent tax years. Brookfield DTLA may also be subject to certain state or local income taxes, or franchise taxes on its REIT activities.
	Brookfield DTLA has made no provision for income taxes in its consolidated and combined financial statements for the years ended December 31, 2014, 2013 and 2012. Brookfield DTLA’s taxable income or loss is different than its financial statement income or loss.
	Brookfield DTLA recognizes tax benefits from uncertain tax positions when it is more likely than not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits. Income tax positions must meet a more likely than not recognition threshold. Brookfield DTLA had no unrecognized tax benefits of December 31, 2014 and 2013, and Brookfield DTLA does not expect its unrecognized tax benefits balance to change during the next 12 months. Brookfield DTLA’s 2013 tax year remains open due to the statute of limitations and may be subject to examination by federal, state and local authorities. The Predecessor Entities’ 2010, 2011 and 2012 tax years as well as the Predecessor Entities’ short tax period ended October 15, 2013 remain open due to the statute of limitations and may be subject to examination by federal, state and local tax authorities.
	Derivative Financial Instruments—
	Brookfield DTLA uses interest rate swap and cap contracts to manage risk from fluctuations in interest rates as well as to hedge anticipated future financing transactions. Interest rate swaps involve the receipt of variable-rate amounts in exchange for fixed-rate payments over the life of the agreements without exchange of the underlying principal amount. Interest rate caps involve the receipt of variable-rate amounts beyond a specified strike price over the life of the agreements without exchange of the underlying principal amount. The Company believes these agreements are with counterparties who are creditworthy financial institutions.
	Brookfield DTLA adheres to the provisions of ASC Subtopic 815-10-15, Derivatives and Hedging (“ASC 815-10-15”). ASC 815-10-15 establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. It requires the recognition of all derivative instruments as assets or liabilities in the Company’s consolidated balance sheet at fair value. Changes in the fair value of derivative instruments that are not designated as hedges, or that do not meet the hedge accounting criteria in ASC 815-10-15, are required to be reported through the statement of operations. Brookfield DTLA has elected to designate its interest rate swap as a cash flow hedge.
	Segment Reporting
	Brookfield DTLA operates in a single reportable segment referred to as its office segment, which includes the operation and management of commercial office properties. Each of Brookfield DTLA’s operating properties is considered a separate operating segment, as each property earns revenues and incurs expenses, individual operating results are reviewed and discrete financial information is available. Management does not distinguish or group Brookfield DTLA’s consolidated operations based on geography, size or type. Brookfield DTLA’s operating properties have similar economic characteristics and provide similar products and services to tenants. As a result, Brookfield DTLA’s operating properties are aggregated into a single reportable segment.
	Accounting for Conditional Asset Retirement Obligations
	Brookfield DTLA has evaluated whether it has any conditional asset retirement obligations, which are a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional upon future events that may or may not be within an entity’s control. The obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing and/or method of settlement. Accordingly, Brookfield DTLA recognized a liability for a conditional asset retirement obligation.

	The cash consideration paid was settled using cash contributed to Brookfield DTLA by Brookfield DTLA Holdings. The fair value of the 9,730,370 shares of Series A preferred stock issued by the Company in the merger was based on an estimate of fair value of $26.00 per share.

A total of 372,901 shares of MPG Preferred Stock were validly tendered into the offer and the holders thereof received the offer price for such shares. At the effective time of the merger, each share of MPG Preferred Stock that was issued and outstanding immediately prior to the merger, including each share of MPG Preferred Stock acquired by DTLA Fund Holding Co. in the offer, was exchanged for one share of Series A preferred stock of the Company with rights, terms and conditions substantially identical to those of the MPG Preferred Stock.
	The acquisition of MPG is being accounted for in accordance with ASC Topic 805, Business Combinations. Brookfield DTLA recognized the assets and liabilities of MPG at fair value in its consolidated balance sheet as of October 15, 2013.

Non-Recourse Carve Out Guarantees
All of Brookfield DTLA’s $2.1 billion of mortgage debt is subject to “non-recourse carve out” guarantees that expire upon elimination of the underlying loan obligations. Under these guarantees, these otherwise non‑recourse loans can become partially or fully recourse against Brookfield DTLA Holdings if certain triggering events occur as defined in the loan agreements. Although these events differ from loan to loan, some of the common events include:
•	The special purpose property-owning subsidiary’s or Brookfield DTLA Holdings’ filing a voluntary petition for bankruptcy;
•	The special purpose property-owning subsidiary’s failure to maintain its status as a special purpose entity;
•	Subject to certain conditions, the special purpose property-owning subsidiary’s failure to obtain the lender’s written consent prior to any subordinate financing or other voluntary lien encumbering the associated property; and
•	Subject to certain conditions, the special purpose property-owning subsidiary’s failure to obtain the lender’s written consent prior to a transfer or conveyance of the associated property, including, in some cases, indirect transfers in connection with a change in control of Brookfield DTLA Holdings or Brookfield DTLA.
In addition, other items that are customarily recourse to a non-recourse carve out guarantor include, but are not limited to, the payment of real property taxes, the breach of representations related to environmental issues or hazardous substances, physical waste of the property, liens which are senior to the mortgage loan and outstanding security deposits.
The maximum amount Brookfield DTLA Holdings would be required to pay under a “non‑recourse carve out” guarantee is the principal amount of the loan (or a total of $2.1 billion as of December 31, 2014 for all loans). This maximum amount does not include liabilities related to environmental issues or hazardous substances. Losses resulting from the breach of our loan agreement representations related to environmental issues or hazardous substances are generally recourse to Brookfield DTLA Holdings pursuant to the “non-recourse carve out” guarantees and any such losses would be in addition to the total principal amounts of the loans. The potential losses are not quantifiable and can be material in certain circumstances, depending on the severity of the environmental or hazardous substance issues. Since each of our non-recourse loans is secured by the office building owned by the special purpose property-owning subsidiary, the amount due to the lender from Brookfield DTLA Holdings in the event a “non-recourse carve out” guarantee is triggered could subsequently be partially or fully mitigated by the net proceeds received from any disposition of the office building; however, such proceeds may not be sufficient to cover the maximum potential amount due, depending on the particular asset.
Debt Reporting
Pursuant to the terms of certain of our mortgage loan agreements, Brookfield DTLA is required to report a debt service coverage ratio (“DSCR”) calculated using the formulas specified in the underlying loan agreements. We have submitted the required reports to the lenders for the measurement periods ended December 31, 2014 and were in compliance with the amounts required by the loan agreements, with the exception of Gas Company Tower.
Under the Gas Company Tower mortgage loan, we reported a DSCR of 0.70 to 1.00, calculated using actual debt service under the loan, and a DSCR of 0.56 to 1.00, calculated using actual debt service plus a hypothetical principal payment using a 30-year amortization schedule. Because the reported DSCR using the actual debt service plus a hypothetical principal payment was less than 1.00 to 1.00, the lender could seek to remove Brookfield Properties Management (CA) Inc. as property manager of Gas Company Tower, which is the only recourse available to the lender as a result of such breach.
Pursuant to the terms of the Gas Company Tower, Wells Fargo Center–South Tower, Wells Fargo Center–North Tower, EY Plaza, and Figueroa at 7th mortgage loan agreements, we are required to provide annual audited financial statements of Brookfield DTLA Holdings to the lenders or agents. The receipt of any opinion other than an “unqualified” audit opinion on our annual audited financial statements is an event of default under the loan agreements for the properties listed above. If an event of default occurs, the lenders have the right to pursue the remedies contained in the loan documents, including acceleration of all or a portion of the debt and foreclosure.

Mezzanine_Equity

Mezzanine Equity	12 Months Ended

Temporary Equity Disclosure [Abstract]
Mezzanine Equity	Mezzanine Equity
	Mezzanine equity in the consolidated balance sheets as of December 31, 2014 and 2013 is comprised of the Series A preferred stock, a Series A-1 preferred interest and a senior participating preferred interest (the “Preferred Interests”). The Series A-1 preferred interest and senior participating preferred interest are held by a noncontrolling interest holder. The Preferred Interests are classified in mezzanine equity because they are callable and the holder of the Series A-1 preferred interest and senior participating preferred interest (which also owns some of the Series A preferred stock) indirectly controls the ability to elect to redeem such instruments, through its controlling interest in the Company and its subsidiaries. There is no commitment or obligation on the part of Brookfield DTLA or Brookfield DTLA Holdings to redeem the Preferred Interests. See “—Senior Participating Preferred Interest” below for a discussion of the distributions paid related to the senior participating preferred interest during 2014.
	The Preferred Interests included within mezzanine equity were recorded at fair value on the date of issuance and have been adjusted to the greater of their carrying amount or redemption value as of December 31, 2014 and 2013. Adjustments to increase the carrying amount to redemption value are recorded in the consolidated statement of operations as a redemption measurement adjustment.
	Other than the distributions paid to the senior participating preferred interest described below, Brookfield DTLA has not paid any cash dividends in the past. Any future dividends declared would be at the discretion of Brookfield DTLA’s board of directors and would depend on its financial condition, results of operations, contractual obligations and the terms of its financing agreements at the time a dividend is considered, and other relevant factors.
	Series A Preferred Stock
	Brookfield DTLA is authorized to issue up to 10,000,000 shares of Series A preferred stock, $0.01 par value per share, with a liquidation preference of $25.00 per share.
	As of December 31, 2014 and 2013, 9,730,370 shares of Series A preferred stock were outstanding, of which 9,357,469 shares were issued to third parties and 372,901 shares were issued to DTLA Fund Holding Co., a subsidiary of Brookfield DTLA Holdings.
	The fair value of the 9,730,370 shares of Series A preferred stock issued by the Company on October 15, 2013 in connection with the merger with MPG was based on an estimate of fair value of $26.00 per share. The valuation was based on available trading information for the MPG Preferred Stock and the Company’s Series A preferred stock on the day prior to and subsequent to the transaction, respectively.
	No dividends were declared on the Series A preferred stock during the years ended December 31, 2014 and 2013. Dividends on the Series A preferred stock are cumulative, and therefore, will continue to accrue at an annual rate of $1.90625 per share. As of December 31, 2014, the cumulative amount of unpaid dividends totals $114.4 million and has been reflected in the carrying amount of the Series A preferred stock.
	The Series A preferred stock does not have a stated maturity and is not subject to any sinking fund or mandatory redemption provisions. Upon liquidation, dissolution or winding up, the Series A preferred stock will rank senior to our common stock with respect to the payment of distributions. We may, at our option, redeem the Series A preferred stock, in whole or in part, for cash at a redemption price of $25.00 per share, plus all accumulated and unpaid dividends on such Series A preferred stock up to and including the redemption date. The Series A preferred stock is not convertible into or exchangeable for any other property or securities of Brookfield DTLA.
	As of December 31, 2014, the Series A preferred stock is reported at its redemption value of $357.6 million calculated using the redemption price of $25.00 per share plus all accumulated and unpaid dividends on such Series A preferred stock through December 31, 2014.
	Series A-1 Preferred Interest
	On October 15, 2013, New OP issued a Series A-1 preferred interest to Brookfield DTLA Holdings or wholly owned subsidiaries of Brookfield DTLA Holdings with a stated value of $225.7 million in connection with the formation of Brookfield DTLA and the MPG acquisition.
	The Series A-1 preferred interest has mirror rights to the Series A preferred interests issued by New OP, which are held by a wholly owned subsidiary of Brookfield DTLA, but only with respect to their respective preferred liquidation preferences, and share pro rata with 48.13% to the Series A-1 preferred interest and 51.87% to the Series A preferred interest based on their current liquidation preferences in accordance with their respective preferred liquidation preferences in distributions from New OP, until their preferred liquidation preferences have been reduced to zero. Thereafter, distributions will be made 47.66% to the Series A preferred interest and 52.34% to the Series B preferred interest, which is held by Brookfield DTLA Holdings. The economic terms of the Series A preferred stock mirror those of the New OP Series A preferred interests, including distributions in respect of the preferred liquidation preference.
	As of December 31, 2014, the Series A-1 preferred interest is reported at its redemption value of $331.9 million calculated using its liquidation value of $225.7 million plus $106.2 million of accumulated and unpaid dividends on such Series A-1 preferred interest through December 31, 2014.
	Senior Participating Preferred Interest
	On October 15, 2013, DTLA OP issued a senior participating preferred interest to Brookfield DTLA Holdings in connection with the formation of Brookfield DTLA and the MPG acquisition. The senior participating preferred interest was comprised of $240.0 million in preferred interests with a 7.0% coupon and a 4.0% participating interest in the residual value of DTLA OP, which owns 333 South Hope and EYP Realty.
	BOA Plaza and EY Plaza were contributed to DTLA OP, directly and indirectly, by Brookfield DTLA in connection with the merger. As of the merger date, these properties had a leverage ratio that was lower than the leverage ratio of the MPG properties acquired, as well as the target leverage ratio that the Company’s management sought to achieve for its properties, as they were refinanced, of approximately 60% to 65%. The size of the preferred interest component of the senior participating preferred interest issued to Brookfield DTLA was based, in part, on the expected net proceeds from the refinancing of the properties owned by 333 South Hope (which holds BOA Plaza) and EYP Realty (which holds EY Plaza) at a leverage ratio in this range and represented a portion of the approximately $595 million fair market value as of the merger date of BOA Plaza and EY Plaza, reduced by the outstanding principal balances of the mortgage loans secured by BOA Plaza and EY Plaza and the $25.0 million promissory note due to BOP Management Inc.
	On March 21, 2014, Brookfield DTLA made a cash distribution to Brookfield DTLA Holdings totaling $70.0 million, in respect of the senior participating preferred interest held by Brookfield DTLA Holdings, which was comprised of $7.3 million in settlement of preferred dividends on the senior participating preferred interest through March 21, 2014 and a return of investment of $62.7 million using proceeds generated by the refinancing of EY Plaza.
	On August 28, 2014, Brookfield DTLA made a cash distribution to Brookfield DTLA Holdings totaling $150.0 million, in respect of the senior participating preferred interest held by Brookfield DTLA Holdings, which was comprised of $5.5 million in settlement of preferred dividends on the senior participating preferred interest through August 28, 2014 and a return of investment of $144.5 million using proceeds generated by the refinancing of BOA Plaza.
	As of December 31, 2014, the senior participating preferred interest is reported at its redemption value of $50.1 million calculated using the value of the preferred and participating interests totaling $49.3 million plus $0.8 million of accumulated and unpaid dividends on the preferred interest through December 31, 2014.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	ASC Topic 820, Fair Value Measurements and Disclosures, defines fair value and establishes a framework for measuring fair value. The objective of fair value is to determine the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price).
	ASC Topic 820 established a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three categories:
	•	Level 1—Quoted prices (unadjusted) in active markets that are accessible at the measurement date.
	•	Level 2—Observable prices that are based on inputs not quoted in active markets, but corroborated by market data.
	•	Level 3—Unobservable prices that are used when little or no market data is available.
	The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. Brookfield DTLA utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs, to the extent possible, as well as consider counterparty credit risk in its assessment of fair value.
	Recurring Measurements
	The valuation of Brookfield DTLA’s interest rate swap is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flow of the derivative. This analysis reflects the contractual terms of the derivative, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. We have incorporated credit valuation adjustments to appropriately reflect both our own and the respective counterparty’s non-performance risk in the fair value measurements.
	Brookfield DTLA’s (liabilities) assets measured at fair value on a recurring basis, aggregated by the level in the fair value hierarchy within which those measurements fall, are as follows (in thousands):
						Fair Value Measurements Using
			Total			Quoted Prices in		Significant			Significant

	Other Financial Instruments
	Brookfield DTLA’s other financial instruments that are exposed to concentrations of credit risk consist primarily of cash and accounts receivable. Management routinely assesses the financial strength of its tenants and, as a consequence, believes that its accounts receivable credit risk exposure is limited. Brookfield DTLA places its temporary cash investments with federally insured institutions. Cash balances with any one institution may at times be in excess of the federally insured limits.
	The estimated fair value and carrying amount of Brookfield DTLA’s mortgage loans are as follows (in thousands):
		December 31, 2014			December 31, 2013
	Estimated fair value	$	2,133,158		$	1,890,436
	Carrying amount	2,118,000			1,897,512
	We calculated the estimated fair value of our mortgage loans by discounting the future contractual cash flows of the loans using current risk adjusted rates available to borrowers with similar credit ratings. The estimated fair value of mortgage loans is classified as Level 3.

	Intercompany Loan
	Brookfield DTLA was indebted to BOP Management Inc. under a $25.0 million promissory note dated October 11, 2013. The note bore interest at 3.25%. For the years ended December 31, 2014 and 2013, the Company accrued $0.6 million and $0.2 million of interest expense, respectively, related to this note. Given the short-term nature of this instrument, fair value was determined to approximate carrying value as of December 31, 2013.
	During September 2014, Brookfield DTLA paid $25.8 million in full settlement of the principal and interest outstanding on the intercompany loan using proceeds from the mortgage loan secured by the Figueroa at 7th retail property.
	Management Agreements
	The Predecessor Entities entered into arrangements with Brookfield Properties Management LLC, which is affiliated with the Company through common ownership through BPO, under which the affiliate provides property management and various other services. On October 15, 2013, these agreements were transferred to BOP Management Inc., an affiliate of BPO. The MPG properties entered into similar arrangements with BOP Management Inc. after the closing of the acquisition on October 15, 2013. Property management fees under these agreements are calculated based on 2.75% of rents collected (as defined in the management agreements). In addition, the Company pays BOP Management Inc. an asset management fee, which is calculated based on 0.75% of the capital contributed to Brookfield DTLA Holdings.
	A summary of costs incurred by Brookfield DTLA and the Predecessor Entities under these arrangements, which are included in rental property operating and maintenance expense in the consolidated and combined statements of operations, is as follows (in thousands):

In addition, Brookfield DTLA’s properties are covered by a terrorism insurance policy that provides aggregate coverage of $4.0 billion for all of BPO’s U.S. properties. Brookfield DTLA is in compliance with the contractual obligations regarding terrorism insurance contained in such policies.
	Prior to their expiration, which became effective on April 19, 2014, the MPG properties were covered under an insurance policy that provided all risk property and business interruption with an aggregate limit of $1.25 billion and a $130.0 million aggregate limit of earthquake insurance, and a terrorism insurance policy with a $1.25 billion aggregate limit. Effective April 19, 2014, the MPG properties were added to the existing BPO insurance policies described above.
	Insurance premiums for Brookfield DTLA are paid by an affiliate company under common control through BPO. Brookfield DTLA reimburses the affiliate company for the actual cost of such premiums.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies
	Tenant Concentration
	Brookfield DTLA generally does not require collateral or other security from its tenants, other than security deposits or letters of credit. Our credit risk is mitigated by the high quality of our existing tenant base, review of prospective tenants’ risk profiles prior to lease execution, and frequent monitoring of our tenant portfolio to identify problem tenants. However, since we have a significant concentration of rental revenue from certain tenants, the inability of those tenants to make their lease payments could have a material adverse effect on our results of operations, cash flow or financial condition.
	A significant portion of Brookfield DTLA’s rental income and tenant reimbursements revenue is generated by a small number of tenants. During the years ended December 31, 2013 and 2012, one tenant, The Capital Group Companies, accounted for more than 10% of our consolidated and combined rental income and tenant reimbursements revenue. No tenant accounted for more than 10% of our consolidated rental income and tenant reimbursements revenue during the year ended December 31, 2014.
	During the years ended December 31, 2013 and 2012, BOA Plaza and EY Plaza each contributed more than 10% of Brookfield DTLA’s consolidated and combined revenue. The revenue generated by these properties totaled 72% and 100% of Brookfield DTLA’s consolidated and combined revenue during the years ended December 31, 2013 and 2012, respectively. During the year ended December 31, 2014, EY Plaza, BOA Plaza, Wells Fargo Center–North Tower, Wells Fargo Center–South Tower, Gas Company Tower and 777 Tower each contributed more than 10% of Brookfield DTLA’s consolidated revenue.
	Litigation
	General—
	Brookfield DTLA and its subsidiaries may be subject to pending legal proceedings and litigation incidental to its business. After consultation with legal counsel, management believes that any liability that may potentially result upon resolution of such matters is not expected to have a material adverse effect on the Company’s business, financial condition or consolidated financial statements as a whole.
	Merger-Related Litigation—
	Following the announcement of the execution of the Agreement and Plan of Merger dated as of April 24, 2013, as amended (the “Merger Agreement”), seven putative class actions were filed against Brookfield Office Properties Inc. (“BPO”), Brookfield DTLA, Brookfield DTLA Holdings LLC, Brookfield DTLA Fund Office Trust Inc., Brookfield DTLA Fund Properties (collectively, the “Brookfield Parties”), MPG Office Trust, Inc., MPG Office, L.P., and the members of MPG Office Trust, Inc.’s board of directors. Five of these lawsuits were filed on behalf of MPG Office Trust, Inc.’s common stockholders: (i) two lawsuits, captioned Coyne v. MPG Office Trust, Inc., et al., No. BC507342 (the “Coyne Action”), and Masih v. MPG Office Trust, Inc., et al., No. BC507962 (the “Masih Action”), were filed in the Superior Court of the State of California in Los Angeles County (the “California State Court”) on April 29, 2013 and May 3, 2013, respectively; and (ii) three lawsuits, captioned Kim v. MPG Office Trust, Inc. et al., No. 24‑C-13-002600 (the “Kim Action”), Perkins v. MPG Office Trust, Inc., et al., No. 24-C-13-002778 (the “Perkins Action”) and Dell’Osso v. MPG Office Trust, Inc., et al., No. 24‑C-13-003283 (the “Dell’Osso Action”) were filed in the Circuit Court for Baltimore City, Maryland on May 1, 2013, May 8, 2013 and May 22, 2013, respectively (collectively, the “Common Stock Actions”). Two lawsuits, captioned Cohen v. MPG Office Trust, Inc. et al., No. 24-C-13-004097 (the “Cohen Action”) and Donlan v. Weinstein, et al., No. 24‑C-13-004293 (the “Donlan Action”), were filed on behalf of MPG Office Trust, Inc.’s preferred stockholders in the Circuit Court for Baltimore City, Maryland on June 20, 2013 and July 2, 2013, respectively (collectively, the “Preferred Stock Actions”).
	In each of the Common Stock Actions, the plaintiffs allege, among other things, that MPG Office Trust, Inc.’s board of directors breached their fiduciary duties in connection with the merger by failing to maximize the value of MPG Office Trust, Inc. and ignoring or failing to protect against conflicts of interest, and that the relevant Brookfield Parties named as defendants aided and abetted those breaches of fiduciary duty. The Kim Action further alleges that MPG Office, L.P. also aided and abetted the breaches of fiduciary duty by MPG Office Trust, Inc.’s board of directors, and the Dell’Osso Action further alleges that MPG Office Trust, Inc. and MPG Office, L.P. aided and abetted the breaches of fiduciary duty by MPG Office Trust, Inc.’s board of directors. On June 4, 2013, the Kim and Perkins plaintiffs filed identical, amended complaints in the Circuit Court for Baltimore City, Maryland. On June 5, 2013, the Masih plaintiffs also filed an amended complaint in the Superior Court of the State of California in Los Angeles County. The three amended complaints, as well as the Dell’Osso Action complaint, allege that the preliminary proxy statement filed by MPG Office Trust, Inc. with the SEC on May 21, 2013 is false and/or misleading because it fails to include certain details of the process leading up to the merger and fails to provide adequate information concerning MPG Office Trust, Inc.’s financial advisors.
	In each of the Preferred Stock Actions, which were brought on behalf of MPG Office Trust, Inc.’s preferred stockholders, the plaintiffs allege, among other things, that, by entering into the Merger Agreement and tender offer, MPG Office Trust, Inc. breached the Articles Supplementary, which governs the issuance of the MPG preferred shares, that MPG Office Trust, Inc.’s board of directors breached their fiduciary duties by agreeing to a merger agreement that violated the preferred stockholders’ contractual rights and that the relevant Brookfield Parties named as defendants aided and abetted those breaches of contract and fiduciary duty. On July 15, 2013, the plaintiffs in the Preferred Stock Actions filed a joint amended complaint in the Circuit Court for Baltimore City, Maryland that further alleged that MPG Office Trust, Inc.’s board of directors failed to disclose material information regarding BPO’s extension of the tender offer.
	The plaintiffs in the seven lawsuits sought an injunction against the merger, rescission or rescissory damages in the event the merger has been consummated, an award of fees and costs, including attorneys’ and experts’ fees, and other relief.
	On July 10, 2013, solely to avoid the costs, risks and uncertainties inherent in litigation, the Brookfield Parties and the other named defendants in the Common Stock Actions signed a memorandum of understanding (the “MOU”), regarding a proposed settlement of all claims asserted therein. The parties subsequently entered into a stipulation of settlement dated November 21, 2013 providing for the release of all asserted claims, additional disclosures by MPG concerning the merger made prior to the merger’s approval, and the payment, by defendants, of an award of attorneys’ fees and expenses in an amount not to exceed $475,000. After a hearing on June 4, 2014, the California State Court granted plaintiffs’ motion for final approval of the settlement and entered a Final Order and Judgment, awarding plaintiffs’ counsel’s attorneys’ fees and expenses in the amount of $475,000, which was paid by MPG Office LLC on June 18, 2014. BPO is seeking reimbursement for the settlement payment from MPG’s insurers.
	In the Preferred Stock Actions, at a hearing on July 24, 2013, the Maryland State Court denied plaintiffs’ motion for preliminary injunction seeking to enjoin the tender offer. The plaintiffs filed a second amended complaint on November 22, 2013 that added additional arguments in support of their allegations that the new preferred shares do not have the same rights as the MPG preferred shares. The defendants moved to dismiss the second amended complaint on December 20, 2013, and briefing on the motion concluded on February 28, 2014. At a hearing on June 18, 2014, the Maryland State Court heard oral arguments on the defendants’ motion to dismiss and reserved judgment on the decision. On October 21, 2014, the parties sent a joint letter to the Maryland State Court stating that since the June 18 meeting, the parties have commenced discussions towards a possible resolution of the lawsuit, requesting that the court temporarily refrain from deciding the pending motion to dismiss to facilitate the discussions, and stating that the parties will report to the court within 45 days of the October 21 letter regarding the status of their discussions.
	Counsel for the parties have reached an agreement to settle the Preferred Stock Actions on a class-wide basis and dismiss the case with prejudice in exchange for the payment of $2.25 per share of Series A preferred stock of accumulated and unpaid dividends to holders of record on a record date to be set after final approval of the settlement by the Maryland State Court, plus any attorneys’ fees awarded by the Maryland State Court to the plaintiffs’ counsel. The dividend will reduce the amount of accumulated and unpaid dividends on the Series A preferred stock, and the terms of the Series A preferred stock will otherwise remain unchanged. The agreement is subject to a number of conditions precedent, further documentation, and approval of the Maryland State Court, after notice to the class. The parties entered into a Memorandum of Understanding on March 30, 2015 memorializing the agreement to settle the Preferred Stock Actions, which has been filed with the Maryland State Court.
	While the final outcome with respect to the Preferred Stock Actions cannot be predicted with certainty, in the opinion of management after consultation with external legal counsel, any liability that may arise from such contingencies would not have a material adverse effect on the financial position, results of operations or liquidity of Brookfield DTLA.

Basis_of_Presentation_and_Summ1

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	Predecessor Entities
	Prior to October 15, 2013, Brookfield DTLA had not conducted any business as a separate company and had no material assets or liabilities. In accordance with accounting principles generally accepted in the United States of America (“GAAP”), the contribution of 333 South Hope and EYP Realty (together, the “Predecessor Entities”) constitute a transaction between entities under common control. A combination between entities that already share the same parent is not considered a business combination because there is no change in control at the parent level. Accordingly, the operations of the Predecessor Entities contributed to Brookfield DTLA by TRZ on October 15, 2013 are presented in the accompanying consolidated and combined financial statements as if they were owned by Brookfield DTLA for all historical periods presented and the assets and liabilities of BOA Plaza and EY Plaza were recorded at the carrying values reflected in the books and records of 333 South Hope and EYP Realty. As such, no gain or loss has been recorded in the consolidated statement of operations for the year ended December 31, 2013 due to this transaction. As a result of the transaction, TRZ’s interest in the Predecessor Entities was exchanged for a preferred and common interest in New OP and a preferred interest in DTLA OP. As a result of certain redemption features in the preferred instruments, these instruments have been classified in the consolidated balance sheet as mezzanine equity. See Note 6 “Mezzanine Equity.”
	As used in these consolidated and combined financial statements and related notes, unless the context requires otherwise, the terms “Brookfield DTLA,” the “Company,” “us,” “we” and “our” refer to the combination of Brookfield DTLA Fund Office Trust Investor Inc. and the Predecessor Entities.
	Principles of Consolidation and Combination and Basis of Presentation
	The accompanying consolidated and combined financial statements are prepared in accordance with GAAP. The consolidated balance sheets as of December 31, 2014 and 2013 include the accounts of Brookfield DTLA and subsidiaries in which it has a controlling financial interest. The accompanying consolidated and combined statements of operations for the year ended December 31, 2013 include the accounts of the Predecessor Entities on a combined basis from January 1, 2013 through October 15, 2013 (the date of the merger); and the consolidated accounts of Brookfield DTLA from October 15, 2013 (the date of the merger) through December 31, 2013. The accompanying combined statements of operations
	for the year ended December 31, 2012 include the accounts of the Predecessor Entities on a combined basis. All intercompany transactions have been eliminated in consolidation and combination as of and for the years ended December 31, 2014, 2013 and 2012.
Consolidation of Variable Interest Entities	In determining whether Brookfield DTLA has a controlling financial interest in an entity and the requirement to consolidate the accounts of that entity, management considers factors such as ownership interest, board representation, management representation, authority to make decisions, and contractual and substantive participating rights of the partners/members as well as whether the entity is a variable interest entity (“VIE”) and Brookfield DTLA is the primary beneficiary.
	A VIE is broadly defined as an entity where either (i) the equity investors as a group, if any, lack the power through voting or similar rights to direct the activities of an entity that most significantly impact the entity’s economic performance or (ii) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support.
	A variable interest holder is considered to be the primary beneficiary of a VIE if it has the power to direct the activities of a variable interest entity that most significantly impact the entity’s economic performance and has the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to the VIE. Brookfield DTLA qualitatively assesses whether it is (or is not) the primary beneficiary of a VIE.
	Consideration of various factors includes, but is not limited to, Brookfield DTLA’s ability to direct the activities that most significantly impact the VIE’s economic performance, its form of ownership interest, its representation on the VIE’s governing body, the size and seniority of its investment, its ability and the rights of other investors to participate in policy making decisions and its ability to replace the manager of and/or liquidate the entity.
	The Company earns a return through an indirect investment in New OP. Brookfield DTLA Holdings, the parent of Brookfield DTLA, owns all of the common interest in New OP. Brookfield DTLA has an indirect preferred stock interest in New OP and its wholly owned subsidiary is the managing member of New OP.
	The Company determined that New OP is a VIE and as a result of having the power to direct the significant activities of New OP and exposure to the economic performance of New OP, Brookfield DTLA meets the two conditions for being the primary beneficiary. Brookfield DTLA is required to continually evaluate its VIE relationships and consolidation conclusion.
Use of Estimates	Use of Estimates
	The preparation of consolidated and combined financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated and combined financial statements and accompanying notes. For example, estimates and assumptions have been made with respect to fair values of assets and liabilities for purposes of applying the acquisition method of accounting, the useful lives of assets, recoverable amounts of receivables, impairment of long‑lived assets and fair value of debt. Actual results could ultimately differ from such estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In April 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2014‑08, Presentation of Financial Statements and Property, Plant, and Equipment: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which requires entities to disclose only disposals representing a strategic shift in operations as discontinued operations. The new guidance requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. The new standard is effective in the first quarter of 2015 for public organizations with calendar year-ends. Early adoption is permitted but only for disposals (or classifications as held for sale) that have not been reported in the financial statements previously issued. We do not believe that this update will have a material effect on Brookfield DTLA’s consolidated financial statements in future periods.
	In May 2014, the FASB issued ASU 2014-09 establishing Accounting Standards Codification Topic 606, Revenue from Contracts with Customers. ASU 2014-09 establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most of the existing revenue recognition guidance. ASU 2014-09 requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration that the entity expects to be entitled to receive in exchange for those goods or services and also requires certain additional disclosures. ASU 2014-09 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2016. We are currently evaluating the impact of the adoption of ASU 2014-09 on Brookfield DTLA’s consolidated financial statements.
	In August 2014, the FASB issued ASU 2014-15. Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This topic provides guidance on management’s responsibility to evaluate whether there is substantial doubt about a company’s ability to continue as a going concern and requires related footnote disclosures. The amendments in this ASU are effective for the annual period ending after December 15, 2016, and for annual and interim periods thereafter. Early adoption is permitted. We are currently evaluating the impact of the adoption of ASU 2014-09 on Brookfield DTLA’s consolidated financial statements.
Business Combinations	Business Combinations—
	Purchase accounting is applied to the assets and liabilities related to all real estate investments acquired from third parties. In accordance with FASB Accounting Standards Codification (“ASC”) Topic 805, Business Combinations, the purchase price of the real estate acquired is allocated to the acquired tangible assets, consisting primarily of land, building and tenant improvements, and identifiable intangible assets and liabilities, consisting of the value of above- and below-market leases, in-place leases, and tenant relationships, based in each case on their fair value.
	The principal valuation technique employed by Brookfield DTLA in determining the fair value of identified assets acquired and liabilities assumed is the income approach, which is then compared to the cost approach. Tangible values for investments in real estate are calculated based on replacement costs for like type quality assets. Above- and below-market lease values are determined by comparing in-place rents with current market rents. In‑place lease amounts are determined by calculating the potential lost revenue during the replacement of the current leases in place. Leasing commissions and legal/marketing fees are determined based upon market allowances pro-rated over the remaining lease terms. Mortgage loans assumed in an acquisition are analyzed using current market terms for similar debt.
	The value of the acquired above-market and below-market leases are amortized and recorded as either a decrease (in the case of above-market leases) or an increase (in the case of below-market leases) to rental income in the consolidated and combined statements of operations over the remaining term of the associated lease. The value of tenant relationships is amortized over the expected term of the relationship, which includes an estimated probability of lease renewal. The value of in-place leases is amortized as an expense over the remaining life of the leases. Amortization of tenant relationships and in‑place leases is included in depreciation and amortization in the consolidated and combined statements of operations.
Investments in Real Estate	Investments in Real Estate—
	Land is carried at cost. Buildings are recorded at historical cost and are depreciated on a straight-line basis over the estimated useful life of the building, which is 60 years with an estimated salvage value of 5%. Building improvements are recorded at historical cost and are depreciated on a straight-line basis over their estimated useful lives, which range from 7 years to 13 years. Tenant improvements that are determined to be assets of Brookfield DTLA are recorded at cost; amortization is included in depreciation and amortization expense in the consolidated and combined statements of operations on a straight-line basis over the shorter of the useful life or the applicable lease term.
	Depreciation expense related to investments in real estate during the years ended December 31, 2014, 2013 and 2012 was $67.5 million, $29.1 million and $19.3 million, respectively.
	Real estate is reviewed for impairment if events or changes in circumstances indicate that the carrying amount of the real estate may not be recoverable. In such an event, a comparison is made of the current and projected operating cash flows of the property into the foreseeable future on an undiscounted basis to the carrying amount of the real estate. If the undiscounted cash flows expected to be generated by an asset are less than its carrying amount, an impairment provision would be recorded to write down the carrying amount of such asset to its fair value. Brookfield DTLA assesses fair value based on estimated cash flow projections utilizing appropriate discount and capitalization rates and available market information. Projections of future cash flow take into account the specific business plan for the property and management’s best estimate of the most probable set of economic conditions expected to prevail in the market. Management believes no impairment of Brookfield DTLA’s real estate assets existed at December 31, 2014 and 2013.
Cash and Cash Equivalents	Cash and Cash Equivalents—
	Cash and cash equivalents include all cash and short-term investments with an original maturity of three months or less.
Restricted Cash	Restricted Cash—
	Restricted cash consists primarily of deposits for tenant improvements and leasing commissions, real estate taxes and insurance reserves, debt service reserves and other items as required by our loan agreements.
Rents, Deferred Rents and Other Receivables, Net	Rents, Deferred Rents and Other Receivables, Net—
	Differences between rental income and the contractual amounts due are recorded as deferred rents receivable in the consolidated balance sheet. Brookfield DTLA evaluates its deferred rents receivable to consider if an allowance is necessary.
	Rents, deferred rents and other receivables, net also includes any amounts paid to a tenant for improvements owned or costs incurred by the tenant are treated as tenant inducements and are presented in the consolidated balance sheet net of accumulated amortization totaling $3.9 million and $2.7 million as of December 31, 2014 and 2013, respectively. Amortization of tenant inducements is recorded on a straight-line basis over the term of the related lease as a reduction of rental income in the consolidated and combined statements of operations.
	Brookfield DTLA periodically evaluates the collectability of amounts due from tenants and maintains an allowance for doubtful accounts in the consolidated balance sheet for estimated losses resulting from the inability of tenants to make required payments under the lease agreements. Management exercises judgment in establishing these allowances and considers payment history and current credit status in developing these estimates.
	The allowance for doubtful accounts for Brookfield DTLA totaled $0.4 million and $0.4 million as of December 31, 2014 and 2013, respectively. For the years ended December 31, 2014 and 2013, Brookfield DTLA recorded provisions for doubtful accounts of $24 thousand and $0.4 million, respectively. There was no provision for doubtful accounts recorded during the year ended December 31, 2012.
Deferred Charges, Net	Deferred Charges, Net—
	Leasing costs, primarily commissions related to leasing activities, are deferred and are presented as deferred charges in the consolidated balance sheet net of accumulated amortization totaling $28.3 million and $17.9 million as of December 31, 2014 and 2013, respectively. Deferred leasing costs amortized on a straight-line basis over the terms of the related leases as part of depreciation and amortization in the consolidated and combined statements of operations.
Prepaid and Other Assets, Net	Prepaid and Other Assets, Net—
	Prepaid and other assets include prepaid insurance, prepaid real estate taxes and other operating costs.
Mortgage Loans, Net	Mortgage Loans, Net—
	Mortgage loans are presented in the consolidated balance sheet net of unamortized debt discounts totaling $6.9 million and $11.9 million as of December 31, 2014 and 2013, respectively.
	Debt discounts totaling $5.0 million, $0.8 million and $0.6 million were amortized during the years ended December 31, 2014, 2013 and 2012, respectively, over the terms of the related mortgage loans on a basis that approximates the effective interest method and were included as part of interest expense in the consolidated and combined statements of operations.
Revenue Recognition	Revenue Recognition—
	Rental income from leases providing for periodic increases in base rent is recognized on a straight-line basis over the noncancelable term of the respective leases. Recoveries of operating expenses and real estate taxes are recorded as tenant reimbursements in the consolidated and combined statements of operations in the period during which the expenses are incurred.
Income Taxes	Income Taxes—
	Brookfield DTLA has elected to be taxed as a real estate investment trust (“REIT”) pursuant to Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”), commencing with its tax year ended December 31, 2013. Brookfield DTLA intends to conduct its operations so as to continue to qualify as a REIT. Accordingly, Brookfield DTLA is not subject to U.S. federal income tax, provided that it continues to qualify as a REIT and distributions to its stockholders, if any, generally equal or exceed its taxable income.
	Qualification and taxation as a REIT depends upon Brookfield DTLA’s ability to meet the various qualification tests imposed under the Code related to annual operating results, asset diversification, distribution levels and diversity of stock ownership. Accordingly, no assurance can be given that Brookfield DTLA will be organized or be able to operate in a manner so as to continue to qualify as a REIT. If Brookfield DTLA fails to qualify as a REIT in any taxable year, it will be subject to federal and state income tax on its taxable income at regular corporate tax rates, and it may be ineligible to qualify as a REIT for four subsequent tax years. Brookfield DTLA may also be subject to certain state or local income taxes, or franchise taxes on its REIT activities.
	Brookfield DTLA has made no provision for income taxes in its consolidated and combined financial statements for the years ended December 31, 2014, 2013 and 2012. Brookfield DTLA’s taxable income or loss is different than its financial statement income or loss.
	Brookfield DTLA recognizes tax benefits from uncertain tax positions when it is more likely than not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits. Income tax positions must meet a more likely than not recognition threshold. Brookfield DTLA had no unrecognized tax benefits of December 31, 2014 and 2013, and Brookfield DTLA does not expect its unrecognized tax benefits balance to change during the next 12 months. Brookfield DTLA’s 2013 tax year remains open due to the statute of limitations and may be subject to examination by federal, state and local authorities. The Predecessor Entities’ 2010, 2011 and 2012 tax years as well as the Predecessor Entities’ short tax period ended October 15, 2013 remain open due to the statute of limitations and may be subject to examination by federal, state and local tax authorities.
Derivative Financial Instruments	Derivative Financial Instruments—
	Brookfield DTLA uses interest rate swap and cap contracts to manage risk from fluctuations in interest rates as well as to hedge anticipated future financing transactions. Interest rate swaps involve the receipt of variable-rate amounts in exchange for fixed-rate payments over the life of the agreements without exchange of the underlying principal amount. Interest rate caps involve the receipt of variable-rate amounts beyond a specified strike price over the life of the agreements without exchange of the underlying principal amount. The Company believes these agreements are with counterparties who are creditworthy financial institutions.
	Brookfield DTLA adheres to the provisions of ASC Subtopic 815-10-15, Derivatives and Hedging (“ASC 815-10-15”). ASC 815-10-15 establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. It requires the recognition of all derivative instruments as assets or liabilities in the Company’s consolidated balance sheet at fair value. Changes in the fair value of derivative instruments that are not designated as hedges, or that do not meet the hedge accounting criteria in ASC 815-10-15, are required to be reported through the statement of operations. Brookfield DTLA has elected to designate its interest rate swap as a cash flow hedge.
Segment Reporting	Segment Reporting
	Brookfield DTLA operates in a single reportable segment referred to as its office segment, which includes the operation and management of commercial office properties. Each of Brookfield DTLA’s operating properties is considered a separate operating segment, as each property earns revenues and incurs expenses, individual operating results are reviewed and discrete financial information is available. Management does not distinguish or group Brookfield DTLA’s consolidated operations based on geography, size or type. Brookfield DTLA’s operating properties have similar economic characteristics and provide similar products and services to tenants. As a result, Brookfield DTLA’s operating properties are aggregated into a single reportable segment.
Accounting for Conditional Asset Retirement Obligations	Accounting for Conditional Asset Retirement Obligations
	Brookfield DTLA has evaluated whether it has any conditional asset retirement obligations, which are a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional upon future events that may or may not be within an entity’s control. The obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing and/or method of settlement. Accordingly, Brookfield DTLA recognized a liability for a conditional asset retirement obligation.
