As of March 31, 2015, Host Inc. holds approximately 99% of Host L.P.’s OP units.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies
	2	Summary of Significant Accounting Policies
	We have condensed or omitted certain information and footnote disclosures normally included in financial statements presented in accordance with GAAP in the accompanying unaudited condensed consolidated financial statements. We believe the disclosures made herein are adequate to prevent the information presented from being misleading. However, the financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10–K for the year ended December 31, 2014.
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	In our opinion, the accompanying financial statements reflect all adjustments necessary to present fairly our financial position as of March 31, 2015, and the results of our operations and cash flows for the quarters ended March 31, 2015 and 2014, respectively. Interim results are not necessarily indicative of full year performance because of the impact of seasonal variations.
	Reclassifications
	Certain prior year financial statement amounts have been reclassified to conform with the current year presentation. In particular, gain on sale of assets, which previously was presented net of tax following income from continuing operations on our statement of operations, has been reclassified to be included in income before income taxes following guidance issued by the SEC upon adoption of ASU 2014-08, Reporting for Discontinued Operations.
	New Accounting Standards
	In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The new standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The standard is effective for annual reporting periods beginning after December 15, 2015. Upon adoption of the standard we will reclassify deferred financing costs, net from total assets to be shown net of debt in the liabilities section of our balance sheet. Adoption of this standard will only affect the presentation of our balance sheet.
	In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis. The ASU amends the consolidation guidance for variable interest entities (VIEs) and general partners' investments in limited partnerships and modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities. The ASU is effective for interim and annual reporting periods beginning after December 15, 2015, with early adoption permitted. We are currently evaluating the effect of the ASU on our consolidated financial statements and related disclosures.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which affects virtually all aspects of an entity’s revenue recognition.  The core principle of the new standard is that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  The standard is effective for annual reporting periods beginning after December 15, 2016, however in April 2015, the FASB proposed to defer the effective date to December 15, 2017. We have not yet completed our assessment of the effect of the new standard on our financial statements, including possible transition alternatives.

Earnings Per Share [Abstract]
Earnings Per Common Share (Unit)
	3	Earnings Per Common Share (Unit)
	Host Inc. Earnings Per Common Share
	Basic earnings per common share is computed by dividing net income attributable to common stockholders by the weighted average number of shares of Host Inc. common stock outstanding. Diluted earnings per common share is computed by dividing net income attributable to common stockholders, as adjusted for potentially dilutive securities, by the weighted average number of shares of Host Inc. common stock outstanding plus other potentially dilutive securities. Dilutive securities may include shares granted under comprehensive stock plans, other non-controlling interests that have the option to convert their limited partnership interests to common OP units and convertible debt securities. No effect is shown for any securities that are anti-dilutive. We have 9.2 million OP units which are convertible into 9.4 million common shares which are not included in Host Inc.’s calculation of earnings per share as their effect is not dilutive. The calculation of basic and diluted earnings per common share is shown below (in millions, except per share amounts):

	-1	There were approximately 31 million potentially dilutive shares for the quarter ended March 31, 2015 related to our exchangeable senior debentures, which shares were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive for the period.
	Host L.P. Earnings Per Common Unit
	Basic earnings per common unit is computed by dividing net income attributable to common unitholders by the weighted average number of common units outstanding. Diluted earnings per common unit is computed by dividing net income attributable to common unitholders, as adjusted for potentially dilutive securities, by the weighted average number of common units outstanding plus other potentially dilutive securities. Dilutive securities may include units distributed to Host Inc. to support Host Inc. common shares granted under comprehensive stock plans, other non-controlling interests that have the option to convert their limited partnership interests to common OP units and convertible debt securities. No effect is shown for any securities that are anti-dilutive. The calculation of basic and diluted earnings per unit is shown below (in millions, except per unit amounts):

	As of March 31, 2015, Host Inc. is the owner of approximately 99% of Host L.P.’s common OP units. The remaining common OP units are held by third party limited partners. Each OP unit may be redeemed for cash or, at the election of Host Inc., Host Inc. common stock, based on the conversion ratio of 1.021494 shares of Host Inc. common stock for each OP unit.
	In exchange for any shares issued by Host Inc., Host L.P. will issue OP units to Host Inc. based on the applicable conversion ratio. Additionally, funds used by Host Inc. to pay dividends on its common stock are provided by distributions from Host L.P.

	Derivatives and Hedging
	Interest rate swap derivatives designated as cash flow hedges. We have designated our floating-to-fixed interest rate swap derivatives as cash flow hedges. The purpose of the interest rate swaps is to hedge against changes in cash flows (interest payments) attributable to fluctuations in variable rate debt. The derivatives are valued based on the prevailing market yield curve on the date of measurement. We also evaluate counterparty credit risk when we calculate the fair value of the swaps. Changes in the fair value of the derivatives are recorded to other comprehensive income (loss) on the accompanying balance sheets. The hedges were fully effective as of March 31, 2015.
	The following table summarizes our interest rate swap derivatives designated as cash flow hedges (in millions):

	Foreign Investment Hedging Instruments. We have five foreign currency forward sale contracts that hedge a portion of the foreign currency exposure resulting from the eventual repatriation of our net investment in foreign operations. These derivatives are considered hedges of the foreign currency exposure of a net investment in a foreign operation and are marked-to-market with changes in fair value recorded to other comprehensive income (loss) within the equity portion of our balance sheet. The foreign currency forward sale contracts are valued based on the forward yield curve of the foreign currency to U.S. dollar forward exchange rate on the date of measurement. We also evaluate counterparty credit risk when we calculate the fair value of the derivatives.

	Fair Value of Other Financial Liabilities. We did not elect the fair value measurement option for any of our other financial liabilities. The fair values of secured debt and our credit facility are determined based on the expected future payments discounted at risk-adjusted rates. Senior Notes and the Exchangeable Senior Debentures are valued based on quoted market prices. The fair values of financial instruments not included in this table are estimated to be equal to their carrying amounts.

	We consider each of our hotels to be an operating segment, none of which meets the threshold for a reportable segment. We also allocate resources and assess operating performance based on individual hotels. All of our other real estate investment activities (primarily office buildings and apartments) are immaterial and, with our operating segments, meet the aggregation criteria, and thus, we report one segment: hotel ownership. Our consolidated foreign operations consist of hotels in six countries. There were no intersegment sales during the periods presented.

Non-Controlling Interests
	9	Non-controlling Interests
	Other Consolidated Partnerships. We consolidate six majority-owned partnerships that have third-party, non-controlling ownership interests. The third-party partnership interests are included in non-controlling interests — other consolidated partnerships on the condensed consolidated balance sheets and totaled $34 million and $32 million as of March 31, 2015 and December 31, 2014, respectively. Two of the partnerships have finite lives that terminate between 2081 and 2095, and the associated non-controlling interests are mandatorily redeemable at our option at the end of, but not prior to, the finite life. At March 31, 2015 and December 31, 2014, the fair values of the non-controlling interests in the partnerships with finite lives were approximately $94 million and $85 million, respectively.
	Net income attributable to non-controlling interests of consolidated partnerships is included in our determination of net income. Net income attributable to non-controlling interests of third parties was $5 million and $4 million for the quarters ended March 31, 2015 and 2014, respectively.
	Host Inc.’s treatment of the non-controlling interests of Host L.P.: Host Inc. adjusts the non-controlling interests of Host L.P. each period so that the amount presented equals the greater of its carrying value based on accumulated historical cost or its redemption value. The historical cost is based on the proportional relationship between the historical cost of equity held by our common stockholders relative to that of the unitholders of Host L.P. The redemption value is based on the amount of cash or Host Inc. common stock, at our option, that would be paid to the non-controlling interests of Host L.P. if it were terminated. Therefore, the redemption value of the common OP units is equivalent to the number of shares that would be issued upon conversion of the common OP units held by third parties valued at the market price of Host Inc. common stock at the balance sheet date. One common OP unit may be exchanged into 1.021494 shares of Host Inc. common stock. Non-controlling interests of Host L.P. are classified in the mezzanine section of our balance sheets as they do not meet the requirements for equity classification because the redemption feature requires the delivery of registered shares.
	The table below details the historical cost and redemption values for the non-controlling interests:
			March 31, 2015		December 31, 2014
	OP units outstanding (millions)			9.2		9.3
	Market price per Host Inc. common share		$	20.18	$	23.77
	Shares issuable upon conversion of one OP unit			1.021494		1.021494
	Redemption value (millions)		$	191	$	225
	Historical cost (millions)			92		94
	Book value (millions) (1)			191		225
	___________
	-1	The book value recorded is equal to the greater of redemption value or historical cost.
	Net income is allocated to the non-controlling interests of Host L.P. based on their weighted average ownership interest during the period. Net income attributable to the non-controlling interests of Host L.P. for the quarters ended March 31, 2015 and 2014 was $1 million and $2 million, respectively.

Commitments And Contingencies Disclosure [Abstract]
Legal Proceedings
	10	Legal Proceedings
	We are involved in various legal proceedings in the normal course of business regarding the operation of our hotels and company matters. To the extent not covered by insurance, these legal proceedings generally fall into the following broad categories: disputes involving hotel-level contracts, employment litigation, compliance with laws such as the Americans with Disabilities Act, tax disputes and other general matters. Under our management agreements, our operators have broad latitude to resolve individual hotel-level claims for amounts generally less than $150,000. However, for matters exceeding such threshold, our operators may not settle claims without our consent.
	Based on our analysis of legal proceedings with which we currently are involved or of which we are aware and our experience in resolving similar claims in the past, we have accrued approximately $4 million as of March 31, 2015 for liabilities related to legal proceedings and estimate that, in the aggregate, our losses related to these proceedings will not exceed $10 million. We believe this range represents the maximum potential loss for all of our legal proceedings. We are not aware of any other matters with a reasonably possible unfavorable outcome for which disclosure of a loss contingency is required. No assurances can be given as to the outcome of any pending legal proceedings.

Accounting Policies [Abstract]
Reclassifications	Reclassifications
	Certain prior year financial statement amounts have been reclassified to conform with the current year presentation. In particular, gain on sale of assets, which previously was presented net of tax following income from continuing operations on our statement of operations, has been reclassified to be included in income before income taxes following guidance issued by the SEC upon adoption of ASU 2014-08, Reporting for Discontinued Operations.
New Accounting Standards	New Accounting Standards
	In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The new standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The standard is effective for annual reporting periods beginning after December 15, 2015. Upon adoption of the standard we will reclassify deferred financing costs, net from total assets to be shown net of debt in the liabilities section of our balance sheet. Adoption of this standard will only affect the presentation of our balance sheet.
	In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis. The ASU amends the consolidation guidance for variable interest entities (VIEs) and general partners' investments in limited partnerships and modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities. The ASU is effective for interim and annual reporting periods beginning after December 15, 2015, with early adoption permitted. We are currently evaluating the effect of the ASU on our consolidated financial statements and related disclosures.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which affects virtually all aspects of an entity’s revenue recognition.  The core principle of the new standard is that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  The standard is effective for annual reporting periods beginning after December 15, 2016, however in April 2015, the FASB proposed to defer the effective date to December 15, 2017. We have not yet completed our assessment of the effect of the new standard on our financial statements, including possible transition alternatives.
