Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization	1. Organization Description of Business Host Hotels & Resorts, Inc. operates as a self-managed and self-administered real estate investment trust (“REIT”), with its operations conducted solely through Host Hotels & Resorts, L.P. and its subsidiaries. Host Hotels & Resorts, L.P., a Delaware limited partnership, operates through an umbrella partnership structure, with Host Hotels & Resorts, Inc., a Maryland corporation, as its sole general partner. In the notes to these unaudited condensed consolidated financial statements, we use the terms “we” or “our” to refer to Host Hotels & Resorts, Inc. and Host Hotels & Resorts, L.P. together, unless the context indicates otherwise. We also use the term “Host Inc.” specifically to refer to Host Hotels & Resorts, Inc. and the term “Host L.P.” specifically to refer to Host Hotels & Resorts, L.P. in cases where it is important to distinguish between Host Inc. and Host L.P. As of March 31, 2018, Host Inc. holds approximately 99% of Host L.P.’s OP units. Consolidated Portfolio As of March 31, 2018, our consolidated portfolio, primarily consisting of luxury and upper upscale hotels, is located in the following countries: Hotels United States 90 Brazil 3 Canada 2 Mexico 1 Total 96 Joint Ventures We own approximately a 33% non-controlling interest in a joint venture in Europe (“Euro JV”) that owns 11 hotels in two separate funds in seven countries. We also own non-controlling interests in an additional six joint ventures that own ten hotels.

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, 2017. 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 unaudited condensed consolidated financial statements reflect all adjustments necessary to present fairly our financial position as of March 31, 2018, and the results of our operations and cash flows for the quarters ended March 31, 2018 and 2017, respectively. Interim results are not necessarily indicative of full year performance because of the impact of seasonal variations. Three of our partnerships are considered variable interest entities (VIEs) as the general partner maintains control over the decisions that most significantly impact the partnerships. This includes the operating partnership, Host L.P., which is consolidated by Host Inc., of which Host Inc. is the sole general partner and holds approximately 99% of its partnership interests; the consolidated partnership that owns the Houston Airport Marriott at George Bush Intercontinental; and the unconsolidated partnership that owns the Philadelphia Marriott Downtown. Host Inc.’s sole significant asset is its investment in Host L.P. and, consequently, substantially all of Host Inc.’s assets and liabilities consist of the assets and liabilities of Host L.P. All of Host Inc.’s debt is an obligation of Host L.P. and may be settled only with assets of Host L.P. Reclassifications Certain prior year financial statement amounts have been reclassified to conform with the current year presentation. New Accounting Standards In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), Business Combinations. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business . The standard adopts a two-step approach wherein, if substantially all of the fair value of the gross assets acquired is concentrated in a single (group of similar) identifiable asset(s), then the transaction will be considered an asset purchase. We adopted this standard effective January 1, 2018. As a result of this standard, we anticipate that the majority of our future hotel purchases will be considered asset purchases as opposed to business combinations, although the determination will be made on a transaction-by-transaction basis. This standard was adopted on a prospective basis and, therefore, it did not affect the accounting for any of our previous transactions. Revenue Recognition. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The standard sets forth steps to determine the timing and amount of revenue to be recognized to depict the transfer of goods or services in an amount that reflects the consideration that the entity expects in exchange. The FASB also issued ASU No. 2017-05, Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) , which is required to be adopted concurrently, as it provides further guidance on accounting for the derecognition of and partial sales of a non-financial asset. This standard may allow for earlier gain recognition for certain sale transactions pursuant to which we have continuing involvement with the asset. We adopted these standards on January 1, 2018, using a modified retrospective approach with a cumulative effect recognized in our equity balance on the date of adoption and no restatements of prior period amounts. When applying the new standard for the cumulative effect, we elected to apply the new standard only to contracts that were not considered completed as of the date of adoption. Transition adjustment. As a result of the adoption of this standard, total liabilities at January 1, 2018 were reduced by $4.5 million, and total equity of Host, Inc. stockholders and total Host L.P. capital at January 1, 2018 increased by $4.5 million. This adjustment is related to a previously deferred gain on the sale of the Atlanta Marriott Marquis in 2013 that would have qualified for recognition under the new standard. Our balance sheet as of March 31, 2018 includes $0.4 million retained as a contingent liability for potential environmental liabilities at the Atlanta Marriott Marquis; however, our potential exposure related to the guarantee can be up to $5 million. Adoption did not have an effect on our income statement for the quarters ended March 31, 2018 and 2017. Policy Disclosure. There has been no significant change to our method of revenue recognition for our primary operations; however, we have updated our accounting policy and disclosures for the revenue recognition standard. See Note 4 for this disclosure.

Earnings Per Share [Abstract]
Earnings Per Common Share (Unit)	3. Earnings Per Common Share (Unit) Basic earnings per common share (unit) is computed by dividing net income attributable to common stockholders (unitholders) by the weighted average number of shares of Host Inc. common stock or Host L.P. common units outstanding. Diluted earnings per common share (unit) is computed by dividing net income attributable to common stockholders (unitholders), as adjusted for potentially dilutive securities, by the weighted average number of shares of Host Inc. common stock or Host L.P. common units outstanding plus other potentially dilutive securities. Dilutive securities may include shares granted under comprehensive stock plans or the common OP units distributed to Host Inc. to support such shares granted, and other non-controlling interests that have the option to convert their limited partnership interests to common OP units. No effect is shown for any securities that are anti-dilutive. We have 8.2 million common OP units which are convertible into 8.4 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 Host Inc. basic and diluted earnings per common share is shown below (in millions, except per share amounts): Quarter ended March 31, 2018 2017 Net income $ 256 $ 161 Less: Net income attributable to non-controlling interests (3 ) (3 ) Net income attributable to Host Inc. $ 253 $ 158 Basic weighted average shares outstanding 739.2 738.0 Assuming distribution of common shares granted under the comprehensive stock plans, less shares assumed purchased at market 0.4 0.2 Diluted weighted average shares outstanding 739.6 738.2 Basic earnings per common share $ .34 $ .21 Diluted earnings per common share $ .34 $ .21 The calculation of Host L.P. basic and diluted earnings per unit is shown below (in millions, except per unit amounts): Quarter ended March 31, 2018 2017 Net income $ 256 $ 161 Less: Net income attributable to non-controlling interests — (1 ) Net income attributable to Host L.P. $ 256 $ 160 Basic weighted average units outstanding 731.9 731.0 Assuming distribution of common shares granted under the comprehensive stock plans, less shares assumed purchased at market 0.3 0.2 Diluted weighted average units outstanding 732.2 731.2 Basic earnings per common unit $ .35 $ .22 Diluted earnings per common unit $ .35 $ .22 ___________

Revenue From Contract With Customer [Abstract]
Revenue	4. Revenue Substantially all of our operating results represent revenues and expenses generated by property-level operations. The majority of payments are made by the customer when the services are provided. Due to the short-term nature of our contracts and the almost concurrent receipt of payment, we have no significant performance obligations outstanding at quarter end. We collect sales, use, occupancy and similar taxes at our hotels, which we present on a net basis (excluded from revenues) on our statements of operations. Revenues are recognized when the performance obligations have been met, as follows: Income statement line item Recognition method Rooms revenues Rooms revenues represent revenues from the occupancy of our hotel rooms and are driven by the occupancy and average daily rate charged. Rooms revenues do not include ancillary services or fees charged. The contracts for room stays with customers are generally very short in duration and revenues are recognized over the course of the hotel stay. Food & beverage revenues Food & beverage (“F&B”) revenues consist of revenue from group functions, which may include banquet revenue and audio-visual revenue, as well as outlet revenue from the restaurants and lounges at our properties. Revenues are recognized as the services or products are provided. Our hotels may employ third parties to provide certain services at the property, for example, audio and visual services. We evaluate each of these contracts to determine if the hotel is the principal or the agent in the transaction, and record the revenues as appropriate (i.e. gross vs. net). Other revenues Other revenues consist of ancillary revenue at the property, including attrition and cancelation fees, golf courses, resort and destination fees, spas, entertainment and other guest services, as well as rental revenue; primarily consisting of leased retail outlets at our properties. Attrition and cancelation fees are recognized for non-cancelable deposits when the customer provides notification of cancelation or is a no-show for the specified date, whichever comes first. Disaggregation of Revenues. While we do not consider the following division to be a reportable segment, we have disaggregated hotel revenues by market location. Our revenues also are presented by country in Note 11 – Geographic Information. By Location. The following table presents hotel revenues for each of the geographic locations in our consolidated hotel portfolio (in millions): Quarter ended March 31, Location 2018 2017 New York $ 161 $ 150 San Diego 133 137 San Francisco/San Jose 107 104 Florida Gulf Coast 98 87 Phoenix 97 98 Maui/Oahu 81 75 Washington, D.C.

Fair Value Measurements	10. Fair Value Measurements Impairment During the first quarter, we recorded an additional impairment loss of $8 million, which is included in depreciation and amortization expense, related to the W New York hotel based on the expected sales price of the property, which sale price is considered an unobservable input (Level 3) in the GAAP fair value hierarchy. The fair value of the property on March 31, 2018 was $183 million. The property was classified as held-for-sale as of December 31, 2017. Other Liabilities 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 our secured debt and our credit facility are determined based on the expected future payments discounted at risk-adjusted rates. Our senior notes 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.

Segment Reporting [Abstract]
Geographic Information	11. Geographic Information 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 three countries as of March 31, 2018. There were no intersegment sales during the periods presented. The following table presents total revenues and property and equipment for each of the geographical areas in which we operate (in millions): Revenues Property and Equipment, net Quarter ended March 31, March 31, December 31, 2018 2017 2018 2017 United States $ 1,320 $ 1,317 $ 10,509 $ 9,548 Australia — 9 — — Brazil 5 5 59 59 Canada 14 10 68 71 Mexico 7 7 14 14 Total $ 1,346 $ 1,348 $ 10,650 $ 9,692

Noncontrolling Interest [Abstract]
Non-Controlling Interests	12. Non-controlling Interests 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 for 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, 2018 December 31, 2017 Common OP units outstanding (millions) 8.2 8.2 Market price per Host Inc. common share $ 18.64 $ 19.85 Shares issuable upon conversion of one common OP unit 1.021494 1.021494 Redemption value (millions) $ 156 $ 167 Historical cost (millions) 81 80 Book value (millions) (1) 156 167 ___________ (1) The book value recorded is equal to the greater of redemption value or historical cost. Other Consolidated Partnerships. We consolidate three majority-owned partnerships that have third-party, non-controlling partners. The third-party partnership interests are included in non-controlling interests — other consolidated partnerships on the balance sheets and totaled $29 million as of both March 31, 2018 and December 31, 2017.

Commitments And Contingencies Disclosure [Abstract]
Legal Proceedings	13. 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 recorded minimal accruals as of March 31, 2018 related to such claims. We have estimated that, in the aggregate, our losses related to these proceedings would not be material. We are not aware of any 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.
New Accounting Standards	New Accounting Standards In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), Business Combinations. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business . The standard adopts a two-step approach wherein, if substantially all of the fair value of the gross assets acquired is concentrated in a single (group of similar) identifiable asset(s), then the transaction will be considered an asset purchase. We adopted this standard effective January 1, 2018. As a result of this standard, we anticipate that the majority of our future hotel purchases will be considered asset purchases as opposed to business combinations, although the determination will be made on a transaction-by-transaction basis. This standard was adopted on a prospective basis and, therefore, it did not affect the accounting for any of our previous transactions. Revenue Recognition. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The standard sets forth steps to determine the timing and amount of revenue to be recognized to depict the transfer of goods or services in an amount that reflects the consideration that the entity expects in exchange. The FASB also issued ASU No. 2017-05, Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) , which is required to be adopted concurrently, as it provides further guidance on accounting for the derecognition of and partial sales of a non-financial asset. This standard may allow for earlier gain recognition for certain sale transactions pursuant to which we have continuing involvement with the asset. We adopted these standards on January 1, 2018, using a modified retrospective approach with a cumulative effect recognized in our equity balance on the date of adoption and no restatements of prior period amounts. When applying the new standard for the cumulative effect, we elected to apply the new standard only to contracts that were not considered completed as of the date of adoption. Transition adjustment. As a result of the adoption of this standard, total liabilities at January 1, 2018 were reduced by $4.5 million, and total equity of Host, Inc. stockholders and total Host L.P. capital at January 1, 2018 increased by $4.5 million. This adjustment is related to a previously deferred gain on the sale of the Atlanta Marriott Marquis in 2013 that would have qualified for recognition under the new standard. Our balance sheet as of March 31, 2018 includes $0.4 million retained as a contingent liability for potential environmental liabilities at the Atlanta Marriott Marquis; however, our potential exposure related to the guarantee can be up to $5 million. Adoption did not have an effect on our income statement for the quarters ended March 31, 2018 and 2017. Policy Disclosure. There has been no significant change to our method of revenue recognition for our primary operations; however, we have updated our accounting policy and disclosures for the revenue recognition standard. See Note 4 for this disclosure.
Revenue Recognition	Revenues are recognized when the performance obligations have been met, as follows: Income statement line item Recognition method Rooms revenues Rooms revenues represent revenues from the occupancy of our hotel rooms and are driven by the occupancy and average daily rate charged. Rooms revenues do not include ancillary services or fees charged. The contracts for room stays with customers are generally very short in duration and revenues are recognized over the course of the hotel stay. Food & beverage revenues Food & beverage (“F&B”) revenues consist of revenue from group functions, which may include banquet revenue and audio-visual revenue, as well as outlet revenue from the restaurants and lounges at our properties. Revenues are recognized as the services or products are provided. Our hotels may employ third parties to provide certain services at the property, for example, audio and visual services. We evaluate each of these contracts to determine if the hotel is the principal or the agent in the transaction, and record the revenues as appropriate (i.e. gross vs. net). Other revenues Other revenues consist of ancillary revenue at the property, including attrition and cancelation fees, golf courses, resort and destination fees, spas, entertainment and other guest services, as well as rental revenue; primarily consisting of leased retail outlets at our properties. Attrition and cancelation fees are recognized for non-cancelable deposits when the customer provides notification of cancelation or is a no-show for the specified date, whichever comes first.
