Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	1. Organization and Description of Business
	Chesapeake Lodging Trust (the “Trust”) is a self-advised real estate investment trust (“REIT”) that was organized in the state of Maryland in June 2009. The Trust is focused on investments primarily in upper-upscale hotels in major business and convention markets and, on a selective basis, premium select-service hotels in urban settings or unique locations in the United States of America (“U.S.”). The Trust completed its initial public offering (“IPO”) in January 2010. The Trust owned no hotels nor had any operations prior to its IPO. As of December 31, 2014, the Trust owned 20 hotels with an aggregate of 6,116 rooms in eight states and the District of Columbia.
	Substantially all of the Trust’s assets are held by, and all of its operations are conducted through, Chesapeake Lodging, L.P., a Delaware limited partnership, which is wholly owned by the Trust (the “Operating Partnership”). For the Trust to qualify as a REIT, it cannot operate hotels. Therefore, the Operating Partnership leases its hotels to CHSP TRS LLC (“CHSP TRS”), which is a wholly owned subsidiary of the Operating Partnership. CHSP TRS then engages hotel management companies to operate the hotels pursuant to management agreements. CHSP TRS is treated as a taxable REIT subsidiary for federal income tax purposes.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies
	Basis of Presentation—The consolidated financial statements presented herein include all of the accounts of Chesapeake Lodging Trust and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
	Cash and Cash Equivalents—The Trust considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.
	Restricted Cash—Restricted cash includes reserves held in escrow for normal replacements of furniture, fixtures and equipment (“FF&E”), property improvement plans (each, a “PIP”), real estate taxes, and insurance pursuant to certain requirements in the Trust’s hotel management, franchise, and loan agreements.
	Investments in Hotels—The Trust allocates the purchase prices of hotels acquired based on the fair value of the property, FF&E, and identifiable intangible assets acquired and the fair value of the liabilities assumed. In making estimates of fair value for purposes of allocating the purchase price, the Trust utilizes a number of sources of information that are obtained in connection with the acquisition of a hotel, including valuations performed by independent third parties and cost segregation studies. The Trust also considers information obtained about each hotel as a result of its pre-acquisition due diligence in estimating the fair value of the tangible and intangible assets acquired and liabilities assumed. Hotel acquisition costs, such as transfer taxes, title insurance, environmental and property condition reviews, and legal and accounting fees, are expensed in the period incurred.
	Property and equipment are depreciated using the straight-line method over the estimated useful lives of the assets, generally 15 to 40 years for buildings and building improvements and three to ten years for FF&E. Leasehold improvements are amortized over the shorter of the lease term or the useful lives of the related assets. Replacements and improvements at the hotels are capitalized, while repairs and maintenance are expensed as incurred. Upon the sale or retirement of property and equipment, the cost and related accumulated depreciation are removed from the Trust’s accounts and any resulting gain or loss is recognized in the consolidated statements of operations.
	Intangible assets and liabilities are recorded on non-market contracts, including air rights, lease, management, and franchise agreements, assumed as part of the acquisition of certain hotels. Above-market and below-market contract values are based on the present value of the difference between contractual amounts to be paid pursuant to the contracts assumed and the Trust’s estimate of the fair market contract rates for corresponding contracts measured over a period equal to the remaining non-cancelable term of the contracts assumed. No value is allocated to market contracts. Intangible assets and liabilities are amortized using the straight-line method over the remaining non-cancelable term of the related contracts.
	The Trust reviews its hotels for impairment whenever events or changes in circumstances indicate that the carrying values of the hotels may not be recoverable. Events or circumstances that may cause a review include, but are not limited to, adverse changes in the demand for lodging at the hotels due to declining national or local economic conditions and/or new hotel construction in markets where the hotels are located. When such conditions exist, management performs an analysis to determine if the estimated undiscounted future cash flows from operations and the proceeds from the ultimate disposition of a hotel exceed its carrying value. If the estimated undiscounted future cash flows are less than the carrying amount of the asset, an adjustment to reduce the carrying amount to the related hotel’s estimated fair market value is recorded and an impairment loss is recognized. No impairment losses have been recognized related to any hotels for the years ended December 31, 2014, 2013 and 2012.
	The Trust classifies a hotel as held for sale in the period in which it has made the decision to dispose of the hotel, a binding agreement to purchase the hotel has been signed under which the buyer has committed a significant amount of nonrefundable cash, and no significant financing contingencies exist which could cause the transaction not to be completed in a timely manner. If these criteria are met, depreciation and amortization of the hotel will cease and an impairment loss will be recognized if the fair value of the hotel, less the costs to sell, is lower than the carrying amount of the hotel. If the sale represents a strategic shift that has (or will have) a major effect on the Trust's operations and financial results, the Trust will classify the loss, together with the related operating results, as discontinued operations in the consolidated statements of operations and will classify the related assets and liabilities as held for sale in the consolidated balance sheets. As of December 31, 2014 and 2013, the Trust had no assets held for sale or liabilities related to assets held for sale.
	Revenue Recognition—Revenues from operations of the hotels are recognized when the services are provided. Revenues consist of room sales, food and beverage sales, and other hotel department revenues, such as parking, marina, telephone, and gift shop sales.
	Prepaid Expenses and Other Assets—Prepaid expenses and other assets consist of prepaid real estate taxes, prepaid insurance, deferred franchise costs, inventories, and other assets.
	Deferred Financing Costs—Deferred financing costs are recorded at cost and consist of loan fees and other costs incurred in issuing debt. Amortization of deferred financing costs is computed using a method that approximates the effective interest method over the term of the related debt and is included in interest expense in the consolidated statements of operations.
	Derivative Instruments—From time to time, the Trust is a party to interest rate swaps, which are considered derivative instruments, in order to manage its interest rate exposure. The Trust’s interest rate risk management objective is to limit the impact of interest rate changes on earnings and cash flows. The Trust records derivative instruments at fair value as either assets or liabilities and designates them as cash flow hedging instruments at inception. The Trust evaluates the hedge effectiveness of the designated cash flow hedging instruments on a quarterly basis and records the effective portion of the change in the fair value of the cash flow hedging instruments as other comprehensive income (loss). Amounts reported in accumulated other comprehensive income (loss) related to cash flow hedging instruments are reclassified to interest expense as interest payments are made on the variable-rate debt being hedged. The Trust does not enter into derivative instruments for trading or speculative purposes and monitors the financial stability and credit standing of its counterparties. As of December 31, 2014, the Trust had no derivative instruments.
	Fair Value Measurements—The Trust accounts for certain assets and liabilities at fair value. In evaluating the fair value of both financial and non-financial assets and liabilities, U.S. generally accepted accounting principles ("GAAP") outlines a valuation framework and creates a fair value hierarchy that distinguishes between market assumptions based on market data (observable inputs) and the reporting entity’s own assumptions about market data (unobservable inputs). The three levels of the fair value hierarchy are as follows:
	Level 1 – Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that are accessible at the measurement date. An active market is defined as a market in which transactions occur with sufficient frequency and volume to provide pricing on an ongoing basis.
	Level 2 – Inputs include quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active (markets with few transactions), inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates, yield curves), and inputs that are derived principally from or corroborated by observable market data correlation or other means.
	Level 3 – Unobservable inputs reflect the reporting entity’s own assumptions about the pricing of an asset or liability when observable inputs are not available or when there is minimal, if any, market activity for an identical or similar asset or liability at the measurement date.
	Income Taxes—The Trust has elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code. As a REIT, the Trust generally will not be subject to federal income tax on that portion of its net income that does not relate to CHSP TRS, the Trust’s wholly owned taxable REIT subsidiary, and that is currently distributed to its shareholders. CHSP TRS, which leases the Trust’s hotels from the Operating Partnership, is subject to federal and state income taxes.
	The Trust accounts for income taxes using the asset and liability method under which deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Valuation allowances are provided if based upon the weight of the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.
	Share-Based Compensation—From time to time, the Trust grants restricted share awards to employees and trustees. To date, the Trust has granted two types of restricted share awards: (1) awards that vest solely on continued employment or service (time-based awards) and (2) awards that vest based on the Trust achieving specified levels of relative total shareholder return and continued employment (performance-based awards). The Trust measures share-based compensation expense for the restricted share awards based on the fair value of the awards on the date of grant. The fair value of time-based awards is determined based on the closing price of the Trust’s common shares on the measurement date, which is generally the date of grant. The fair value of performance-based awards is determined using a Monte Carlo simulation performed by an independent third party. For time-based awards, share-based compensation expense is recognized on a straight-line basis over the life of the entire award. For performance-based awards, share-based compensation expense is recognized over the requisite service period for each award. No share-based compensation expense is recognized for awards for which employees or trustees do not render the requisite service.
	Earnings Per Share—Basic earnings per share is computed by dividing net income available to common shareholders, adjusted for dividends declared on and undistributed earnings allocated to unvested time-based awards, by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income available to common shareholders, adjusted for dividends declared on and undistributed earnings allocated to unvested time-based awards, by the weighted-average number of common shares outstanding, plus potentially dilutive securities, such as unvested performance-based awards, during the period. The Trust’s unvested time-based awards are entitled to receive non-forfeitable dividends, if declared. Therefore, unvested time-based awards qualify as participating securities, requiring the allocation of dividends and undistributed earnings under the two-class method to calculate basic earnings per share. The percentage of undistributed earnings allocated to the unvested time-based awards is based on the proportion of the weighted-average unvested time-based awards outstanding during the period to the total of the weighted-average common shares and unvested time-based awards outstanding during the period. No adjustment is made for shares that are anti-dilutive during the period.
	Segment Information—The Trust has determined that its business is conducted in one reportable segment, hotel ownership.
	Use of Estimates—The preparation of the consolidated 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	Recent Accounting Pronouncements—In April 2014, the Financial Accounting Standards Board (the “FASB”) issued updated accounting guidance for reporting discontinued operations and disposals of components of an entity. Under the new accounting guidance, only components of an entity disposed of or classified as held for sale representing a strategic shift that have (or will have) a major effect on an entity’s operations and financial results should be reported as discontinued operations. The update also expands the disclosure requirements for discontinued operations and adds new disclosures for individually significant dispositions that do not meet the definition of discontinued operations. The new accounting guidance is to be applied prospectively and is effective for interim and annual periods beginning on or after December 15, 2014 (early adoption is permitted only for disposals that have not been previously reported). The Trust early adopted the new accounting guidance effective July 1, 2014.
	In May 2014, the FASB issued updated accounting guidance for recognition of revenue from contracts with customers. The comprehensive new accounting guidance will supersede existing revenue recognition guidance and require revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. The new accounting guidance is to be applied prospectively and is effective for interim and annual periods beginning on or after December 15, 2016. The Trust will adopt the new accounting guidance on January 1, 2017. The Trust does not believe that the adoption of this guidance will have a material impact on the consolidated financial statements.

	On September 30, 2014, the Trust sold the 153-room Courtyard Anaheim at Disneyland Resort located in Anaheim, California for $32.5 million, including sold working capital. Net proceeds from the sale were $31.8 million, which resulted in the recognition of a gain on sale of $7.0 million. This sale did not represent a strategic shift that has (or will have) a major effect on the Trust's operations and financial results, and therefore, did not qualify to be reported as discontinued operations.

	-1	The Trust may exercise an option to extend the maturity by one year, subject to certain customary conditions. As of December 31, 2014, the interest rate in effect was 1.92%. See below for additional information related to the revolving credit facility.
	-2	At origination, $25.0 million was advanced by the lender and was secured by the Hyatt Herald Square New York. On March 14, 2013, $35.0 million was advanced by the lender in connection with the acquisition of the Hyatt Place New York Midtown South. Following the subsequent advance, the entire $60.0 million principal amount of the loan was secured by both hotels. The loan bore interest equal to LIBOR plus 3.25%. Contemporaneous with the origination of the term loan, the Trust entered into an interest rate swap to effectively fix the interest rate on the initial $25.0 million advance for the original two-year term at 3.75% per annum. Under the terms of this interest rate swap, the Trust paid fixed interest of 0.50% per annum on a notional amount of $25.0 million and received floating rate interest equal to the one-month LIBOR. The effective date of this interest rate swap was July 3, 2012 and it matured on July 3, 2014. Contemporaneous with the subsequent advance, the Trust entered into an interest rate swap to effectively fix the interest rate on the $35.0 million subsequent advance for the remaining initial term of the loan at 3.65% per annum. Under the terms of this interest rate swap, the Trust paid fixed interest of 0.40% per annum on a notional amount of $35.0 million and received floating rate interest equal to the one-month LIBOR. The effective date of this interest rate swap was March 14, 2013 and it matured on July 3, 2014. The Trust repaid the term loan at maturity on July 3, 2014.
	-3	On June 30, 2011, in connection with the acquisition of the Courtyard Washington Capitol Hill/Navy Yard, the Trust assumed an existing loan agreement with an outstanding principal balance of $37.5 million. Based on interest rates on similar types of debt instruments at the time of assumption, the Trust recorded the loan at its estimated fair value of $38.6 million, which included a premium on mortgage loan of $1.1 million. Amortization of premium on mortgage loan is computed using a method that approximates the effective interest method over the term of the loan agreement and is included in interest expense in the consolidated statements of operations.
	-4	The loan has a term of 30 years, but is callable by the lender after 10 years, and the Trust expects the lender to call the loan at that time. The indicated maturity is based on the date the loan is callable by the lender.
	-5	The loan requires interest-only payments for the first two years and principal and interest payments thereafter.
	Revolving credit facility
	On July 30, 2010, the Trust entered into a credit agreement to obtain a $115.0 million, two-year secured revolving credit facility with a syndicate of banks. Borrowings under the revolving credit facility bore interest equal to LIBOR plus 3.75%, subject to a LIBOR floor of 2.00%. On January 21, 2011, the Trust amended the credit agreement to increase the maximum size of the revolving credit facility from $115.0 million to $150.0 million. On October 14, 2011, the Trust further amended the credit agreement by (1) increasing the maximum size of the revolving credit facility from $150.0 million to $200.0 million, (2) lowering the interest rate to LIBOR plus 2.75% - 3.75% (the spread over LIBOR based on the Trust's consolidated leverage ratio) and (3) extending the maturity date to October 14, 2014.
	On October 25, 2012, the Trust further amended the credit agreement by (1) increasing the maximum size of the revolving credit facility from $200.0 million to $250.0 million, (2) lowering the interest rate to LIBOR plus 1.75% - 2.75% (the spread over LIBOR continues to be based on the Trust's consolidated leverage ratio), and (3) extending the maturity date to April 25, 2016. The amended credit agreement provides for the possibility of further future increases, up to a maximum of $375.0 million, in accordance with the terms of the amended credit agreement. The amended credit agreement also provides for an extension of the maturity date by one year, subject to satisfaction of certain customary conditions.
	The amount that the Trust can borrow under the revolving credit facility is based on the value of the Trust's hotels included in the borrowing base, as defined in the amended credit agreement. As of December 31, 2014, the revolving credit facility was secured by eight hotels providing borrowing availability of $250.0 million, of which no amount was outstanding. The amended credit agreement contains standard financial covenants, including certain leverage ratios, coverage ratios, and a minimum tangible net worth requirement.
	Other
	Certain of the Trust's mortgage loan agreements contain standard financial covenants relating to coverage ratios and standard provisions that require loan servicers to maintain escrow accounts for certain items, including real estate taxes, insurance premiums, the completion of PIPs, and normal replacements of FF&E.
	As of December 31, 2014, the Trust was in compliance with all financial covenants under its borrowing arrangements. As of December 31, 2014, the Trust’s weighted-average interest rate on its long-term debt was 4.37%. Future scheduled principal payments of debt obligations (assuming no exercise of extension options) as of December 31, 2014 are as follows (in thousands):

Equity Plan	10. Equity Plan
	In January 2010, the Trust established the Chesapeake Lodging Trust Equity Plan (the “Plan”), which provides for the issuance of equity-based awards, including restricted shares, unrestricted shares, share options, share appreciation rights, and other awards based on the Trust’s common shares. Employees and trustees of the Trust and other persons that provide services to the Trust are eligible to participate in the Plan. The compensation committee of the board of trustees administers the Plan and determines the number of awards to be granted, the vesting period, and the exercise price, if any.
	The Trust initially reserved 454,657 common shares for issuance under the Plan at its establishment. In May 2012, the Trust’s common shareholders approved an amendment to the Plan such that the number of shares available for issuance under the Plan was increased by 2,750,000. Shares that are issued under the Plan to any person pursuant to an award are counted against this limit as one share for every one share granted. If any shares covered by an award are not purchased or are forfeited, if an award is settled in cash, or if an award otherwise terminates without delivery of any shares, then the number of common shares counted against the aggregate number of shares available under the Plan with respect to the award will, to the extent of any such forfeiture or termination, again be available for making awards under the Plan. As of December 31, 2014, subject to increases that may result in the case of any future forfeiture or termination of currently outstanding awards, 1,558,223 common shares were reserved and available for future issuances under the Plan.
	The Trust will make appropriate adjustments to outstanding awards and the number of shares available for issuance under the Plan, including the individual limitations on awards, to reflect share dividends, share splits, spin-offs and other similar events. While the compensation committee can terminate or amend the Plan at any time, no amendment can adversely impair the rights of grantees with respect to outstanding awards. In addition, an amendment will be contingent on approval of the Trust’s common shareholders to the extent required by law or if the amendment would materially increase the benefits accruing to participants under the Plan, materially increase the aggregate number of shares that can be issued under the Plan, or materially modify the requirements as to eligibility for participation in the Plan. Unless terminated earlier, the Plan will terminate in January 2020, but will continue to govern unexpired awards.
	For the year ended December 31, 2012, the Trust granted 192,900 restricted common shares to certain employees and trustees, all of which were time-based awards. The time-based awards are generally eligible to vest at the rate of one-fourth of the number of restricted shares granted commencing on the first anniversary of their issuance.
	For the year ended December 31, 2013, the Trust granted 537,400 restricted common shares to certain employees and trustees, of which 192,500 shares were time-based awards and 344,900 shares were performance-based awards (the "2013 Performance-Based Awards"). The time-based awards are generally eligible to vest at the rate of one-fourth of the number of restricted shares granted commencing on the first anniversary of their issuance. The 2013 Performance-Based Awards are eligible to vest at the rate of one-fourth of the number of restricted shares granted commencing on December 31, 2013 and each year thereafter. Additional vesting of the 2013 Performance-Based Awards can also occur at December 31, 2016. Dividends on the 2013 Performance-Based Awards accrue, but are not paid unless the related shares vest. The fair value of the 2013 Performance-Based Awards was $14.84 per share and was determined using a Monte Carlo simulation with the following assumptions: volatility of 31.15%; an expected term equal to the requisite service period for the awards; and a risk-free interest rate of 0.55%.
	For the year ended December 31, 2014, the Trust granted 491,564 restricted common shares to certain employees and trustees, of which 158,941 shares were time-based awards and 332,623 shares were performance-based awards (the “2014 Performance-Based Awards”). The time-based awards are generally eligible to vest at the annual rate of one-third of the number of restricted shares granted commencing on the first anniversary of their issuance. The 2014 Performance-Based Awards are eligible to vest at December 31, 2016. Dividends on the 2014 Performance-Based Awards accrue, but are not paid unless the related shares vest. The fair value of the 2014 Performance-Based Awards was $8.98 per share and was determined using a Monte Carlo simulation with the following assumptions: volatility of 29.34%; an expected term equal to the requisite service period for the awards; and a risk-free interest rate of 0.72%.
	The actual number of shares under the 2013 Performance-Based Awards that vest in a particular year will be based on the Trust’s annual total shareholder return (“TSR”), as defined in the restricted share agreements, relative to the annual total return generated by the SNL US Hotel REIT Index prepared by SNL Financial LC (the “Index”). Additional vesting of any previously unvested shares under the 2013 Performance-Based Awards can also occur based on the Trust’s TSR, measured over a four-year period ending December 31, 2016, relative to the total return generated by the Index. The actual number of shares under the 2014 Performance-Based Awards that vest will be based on the Trust’s TSR, measured over a three-year period ending December 31, 2016, relative to the total return generated by the Index. The payout schedule for the 2013 Performance-Based Awards and the 2014 Performance-Based Awards is as follows, with linear interpolation for performance between 67% and 100%, and between 100% and 133% of the Index:
	Trust TSR as % of	Payout
	Index Total Return	(% of Maximum)
	<67%	0%
	67%	25%
	100%	50%
	≥133%	100%
	If the Trust’s TSR is negative for a performance period, shares under the 2013 Performance-Based Awards will vest for that period if the Trust’s TSR equals or exceeds 133% of the Index’s total return, in which case 100% of the shares subject to vesting will vest, and no shares under the 2014 Performance-Based Awards will vest. If the Trust’s TSR is positive for a performance period and the total return of the Index is negative, 100% of the shares subject to vesting under the 2013 Performance-Based Awards and the 2014 Performance-Based Awards will vest.
	As of December 31, 2014, there was approximately $9.9 million of unrecognized share-based compensation expense related to restricted common shares. The unrecognized share-based compensation expense is expected to be recognized over a weighted-average period of 2.0 years. The following is a summary of the Trust’s restricted common share activity for the years ended December 31, 2014, 2013 and 2012:

	The Trust’s financial instruments include cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses, and long-term debt. The carrying values reported in the consolidated balance sheets for cash and cash equivalents, restricted cash, accounts receivable, and accounts payable and accrued expenses approximate fair value. The Trust estimates the fair value of its fixed rate debt by discounting the future cash flows of each instrument using estimated market rates of debt instruments with similar maturities and credit profiles. These inputs are classified as Level 3 within the fair value hierarchy. As of December 31, 2014, the carrying value reported in the consolidated balance sheet for the Trust's long-term debt approximated its fair value.

Accordingly, no valuation allowance has been recorded as of December 31, 2014.
	As of December 31, 2014, the tax years that remain subject to examination by major tax jurisdictions generally include 2011 through 2014. In September 2014, the Trust received notification from the U.S. Internal Revenue Service (the “IRS”) that CHSP TRS has been selected for a compliance research examination for its tax years ended December 31, 2012 and 2011. As of February 19, 2015, CHSP TRS has not yet received a Revenue Agent’s Report, generally issued at the conclusion of an IRS examination, and the examination remains open.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	14. Commitments and Contingencies
	Management Agreements—The Trust’s hotels operate pursuant to management agreements with various third-party management companies. Each management company receives a base management fee generally between 2% and 4% of hotel revenues. The management companies are also eligible to receive an incentive management fee if hotel operating income, as defined in the management agreements, exceeds certain performance thresholds. The incentive management fee is generally calculated as a percentage of hotel operating income after the Trust has received a priority return on its investment in the hotel.
	Franchise Agreements—As of December 31, 2014, 11 of the Trust’s hotels operated pursuant to franchise agreements with hotel brand companies and nine hotels operated pursuant to management agreements with hotel brand companies that allowed them to operate under their respective brands. Under the 11 franchise agreements, the Trust generally pays a royalty fee ranging from 3% to 6% of room revenues and up to 3% of food and beverage revenues, plus additional fees for marketing, central reservation systems, and other franchisor costs that amount to between 1% and 5% of room revenues.
	Ground Lease Agreements—The Trust leases the land underlying the Hyatt Regency Mission Bay Spa and Marina pursuant to a lease agreement, which has an initial term ending January 2056. Rent due under the lease agreement is the greater of base rent or percentage rent. Base rent is currently $2.2 million per year. Base rent resets every three years over the remaining term of the lease equal to 75% of the average of the actual rent paid over the two years preceding the base rent reset year. The next base rent reset year is 2016. Annual percentage rent is calculated based on various percentages of the hotel's various sources of revenue, including room, food and beverage, and marina rentals, earned during the period.
	The Trust also leases the land underlying the JW Marriott San Francisco Union Square pursuant to a lease agreement, which has a term ending January 2083. Rent due under the lease agreement is the greater of base rent or percentage rent. Base rent is currently $1.7 million per year. Base rent resets every five years over the remaining term of the lease based on the level of inflation, as defined in the agreement, over the preceding five years, but in no event resulting in an increase of more than 125% of the base rent in effect immediately prior to the reset year (nor subject to any decrease). The next base rent reset year is 2019. In January 2034, base rent will reset to 10% of the fair market value of the underlying land as determined by a valuation performed by an independent third party, if such reset results in an increase over the base rent in effect immediately prior to the reset year. Annual percentage rent is calculated based on various percentages of the hotel's various sources of revenue, including room and food and beverage, earned during the period.
	FF&E Reserves—Pursuant to its management, franchise and loan agreements, the Trust is required to establish a FF&E reserve for each hotel to cover the cost of replacing FF&E. Contributions to the FF&E reserve are based on a percentage of gross revenues at each hotel. The Trust is generally required to contribute between 3% and 5% of gross revenues over the term of the agreements.
	Litigation—The Trust is not involved in any material litigation nor, to its knowledge, is any material litigation threatened against the Trust.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation—The consolidated financial statements presented herein include all of the accounts of Chesapeake Lodging Trust and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Cash and Cash Equivalents	Cash and Cash Equivalents—The Trust considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.
Restricted Cash	Restricted Cash—Restricted cash includes reserves held in escrow for normal replacements of furniture, fixtures and equipment (“FF&E”), property improvement plans (each, a “PIP”), real estate taxes, and insurance pursuant to certain requirements in the Trust’s hotel management, franchise, and loan agreements.
Investments in Hotels	Investments in Hotels—The Trust allocates the purchase prices of hotels acquired based on the fair value of the property, FF&E, and identifiable intangible assets acquired and the fair value of the liabilities assumed. In making estimates of fair value for purposes of allocating the purchase price, the Trust utilizes a number of sources of information that are obtained in connection with the acquisition of a hotel, including valuations performed by independent third parties and cost segregation studies. The Trust also considers information obtained about each hotel as a result of its pre-acquisition due diligence in estimating the fair value of the tangible and intangible assets acquired and liabilities assumed. Hotel acquisition costs, such as transfer taxes, title insurance, environmental and property condition reviews, and legal and accounting fees, are expensed in the period incurred.
	Property and equipment are depreciated using the straight-line method over the estimated useful lives of the assets, generally 15 to 40 years for buildings and building improvements and three to ten years for FF&E. Leasehold improvements are amortized over the shorter of the lease term or the useful lives of the related assets. Replacements and improvements at the hotels are capitalized, while repairs and maintenance are expensed as incurred. Upon the sale or retirement of property and equipment, the cost and related accumulated depreciation are removed from the Trust’s accounts and any resulting gain or loss is recognized in the consolidated statements of operations.
	Intangible assets and liabilities are recorded on non-market contracts, including air rights, lease, management, and franchise agreements, assumed as part of the acquisition of certain hotels. Above-market and below-market contract values are based on the present value of the difference between contractual amounts to be paid pursuant to the contracts assumed and the Trust’s estimate of the fair market contract rates for corresponding contracts measured over a period equal to the remaining non-cancelable term of the contracts assumed. No value is allocated to market contracts. Intangible assets and liabilities are amortized using the straight-line method over the remaining non-cancelable term of the related contracts.
	The Trust reviews its hotels for impairment whenever events or changes in circumstances indicate that the carrying values of the hotels may not be recoverable. Events or circumstances that may cause a review include, but are not limited to, adverse changes in the demand for lodging at the hotels due to declining national or local economic conditions and/or new hotel construction in markets where the hotels are located. When such conditions exist, management performs an analysis to determine if the estimated undiscounted future cash flows from operations and the proceeds from the ultimate disposition of a hotel exceed its carrying value. If the estimated undiscounted future cash flows are less than the carrying amount of the asset, an adjustment to reduce the carrying amount to the related hotel’s estimated fair market value is recorded and an impairment loss is recognized. No impairment losses have been recognized related to any hotels for the years ended December 31, 2014, 2013 and 2012.
	The Trust classifies a hotel as held for sale in the period in which it has made the decision to dispose of the hotel, a binding agreement to purchase the hotel has been signed under which the buyer has committed a significant amount of nonrefundable cash, and no significant financing contingencies exist which could cause the transaction not to be completed in a timely manner. If these criteria are met, depreciation and amortization of the hotel will cease and an impairment loss will be recognized if the fair value of the hotel, less the costs to sell, is lower than the carrying amount of the hotel. If the sale represents a strategic shift that has (or will have) a major effect on the Trust's operations and financial results, the Trust will classify the loss, together with the related operating results, as discontinued operations in the consolidated statements of operations and will classify the related assets and liabilities as held for sale in the consolidated balance sheets. As of December 31, 2014 and 2013, the Trust had no assets held for sale or liabilities related to assets held for sale.
Revenue Recognition	Revenue Recognition—Revenues from operations of the hotels are recognized when the services are provided. Revenues consist of room sales, food and beverage sales, and other hotel department revenues, such as parking, marina, telephone, and gift shop sales.
Prepaid Expenses and Other Assets	Prepaid Expenses and Other Assets—Prepaid expenses and other assets consist of prepaid real estate taxes, prepaid insurance, deferred franchise costs, inventories, and other assets.
Deferred Financing Costs	Deferred Financing Costs—Deferred financing costs are recorded at cost and consist of loan fees and other costs incurred in issuing debt. Amortization of deferred financing costs is computed using a method that approximates the effective interest method over the term of the related debt and is included in interest expense in the consolidated statements of operations.
Derivative Instruments	Derivative Instruments—From time to time, the Trust is a party to interest rate swaps, which are considered derivative instruments, in order to manage its interest rate exposure. The Trust’s interest rate risk management objective is to limit the impact of interest rate changes on earnings and cash flows. The Trust records derivative instruments at fair value as either assets or liabilities and designates them as cash flow hedging instruments at inception. The Trust evaluates the hedge effectiveness of the designated cash flow hedging instruments on a quarterly basis and records the effective portion of the change in the fair value of the cash flow hedging instruments as other comprehensive income (loss). Amounts reported in accumulated other comprehensive income (loss) related to cash flow hedging instruments are reclassified to interest expense as interest payments are made on the variable-rate debt being hedged. The Trust does not enter into derivative instruments for trading or speculative purposes and monitors the financial stability and credit standing of its counterparties. As of December 31, 2014, the Trust had no derivative instruments.
Fair Value Measurements	Fair Value Measurements—The Trust accounts for certain assets and liabilities at fair value. In evaluating the fair value of both financial and non-financial assets and liabilities, U.S. generally accepted accounting principles ("GAAP") outlines a valuation framework and creates a fair value hierarchy that distinguishes between market assumptions based on market data (observable inputs) and the reporting entity’s own assumptions about market data (unobservable inputs). The three levels of the fair value hierarchy are as follows:
	Level 1 – Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that are accessible at the measurement date. An active market is defined as a market in which transactions occur with sufficient frequency and volume to provide pricing on an ongoing basis.
	Level 2 – Inputs include quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active (markets with few transactions), inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates, yield curves), and inputs that are derived principally from or corroborated by observable market data correlation or other means.
	Level 3 – Unobservable inputs reflect the reporting entity’s own assumptions about the pricing of an asset or liability when observable inputs are not available or when there is minimal, if any, market activity for an identical or similar asset or liability at the measurement date.
Income Taxes	Income Taxes—The Trust has elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code. As a REIT, the Trust generally will not be subject to federal income tax on that portion of its net income that does not relate to CHSP TRS, the Trust’s wholly owned taxable REIT subsidiary, and that is currently distributed to its shareholders. CHSP TRS, which leases the Trust’s hotels from the Operating Partnership, is subject to federal and state income taxes.
	The Trust accounts for income taxes using the asset and liability method under which deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Valuation allowances are provided if based upon the weight of the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.
Share-Based Compensation	Share-Based Compensation—From time to time, the Trust grants restricted share awards to employees and trustees. To date, the Trust has granted two types of restricted share awards: (1) awards that vest solely on continued employment or service (time-based awards) and (2) awards that vest based on the Trust achieving specified levels of relative total shareholder return and continued employment (performance-based awards). The Trust measures share-based compensation expense for the restricted share awards based on the fair value of the awards on the date of grant. The fair value of time-based awards is determined based on the closing price of the Trust’s common shares on the measurement date, which is generally the date of grant. The fair value of performance-based awards is determined using a Monte Carlo simulation performed by an independent third party. For time-based awards, share-based compensation expense is recognized on a straight-line basis over the life of the entire award. For performance-based awards, share-based compensation expense is recognized over the requisite service period for each award. No share-based compensation expense is recognized for awards for which employees or trustees do not render the requisite service.
Earnings Per Share	Earnings Per Share—Basic earnings per share is computed by dividing net income available to common shareholders, adjusted for dividends declared on and undistributed earnings allocated to unvested time-based awards, by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income available to common shareholders, adjusted for dividends declared on and undistributed earnings allocated to unvested time-based awards, by the weighted-average number of common shares outstanding, plus potentially dilutive securities, such as unvested performance-based awards, during the period. The Trust’s unvested time-based awards are entitled to receive non-forfeitable dividends, if declared. Therefore, unvested time-based awards qualify as participating securities, requiring the allocation of dividends and undistributed earnings under the two-class method to calculate basic earnings per share. The percentage of undistributed earnings allocated to the unvested time-based awards is based on the proportion of the weighted-average unvested time-based awards outstanding during the period to the total of the weighted-average common shares and unvested time-based awards outstanding during the period. No adjustment is made for shares that are anti-dilutive during the period.
Segment Information	Segment Information—The Trust has determined that its business is conducted in one reportable segment, hotel ownership.
Use of Estimates	Use of Estimates—The preparation of the consolidated 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements—In April 2014, the Financial Accounting Standards Board (the “FASB”) issued updated accounting guidance for reporting discontinued operations and disposals of components of an entity. Under the new accounting guidance, only components of an entity disposed of or classified as held for sale representing a strategic shift that have (or will have) a major effect on an entity’s operations and financial results should be reported as discontinued operations. The update also expands the disclosure requirements for discontinued operations and adds new disclosures for individually significant dispositions that do not meet the definition of discontinued operations. The new accounting guidance is to be applied prospectively and is effective for interim and annual periods beginning on or after December 15, 2014 (early adoption is permitted only for disposals that have not been previously reported). The Trust early adopted the new accounting guidance effective July 1, 2014.
	In May 2014, the FASB issued updated accounting guidance for recognition of revenue from contracts with customers. The comprehensive new accounting guidance will supersede existing revenue recognition guidance and require revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. The new accounting guidance is to be applied prospectively and is effective for interim and annual periods beginning on or after December 15, 2016. The Trust will adopt the new accounting guidance on January 1, 2017. The Trust does not believe that the adoption of this guidance will have a material impact on the consolidated financial statements.

	-1	In conjunction with the acquisition of the Hyatt Regency Boston on March 18, 2010, the Trust acquired an air rights contract which expires in September 2079 and that requires no payments through maturity. The Trust recorded the fair value of the air rights contract of $36.1 million as an intangible asset and is amortizing the value over the term of the contract.
	-2	In conjunction with the acquisition of the Denver Marriott City Center on October 3, 2011, the Trust assumed three lease agreements for land parcels underlying a portion of the hotel with initial terms ending July 2068, February 2072 and April 2072. The Trust concluded that the terms of two of the three ground leases were below market terms and recorded an aggregate of $4.8 million of favorable ground lease assets, which the Trust is amortizing over the life of the respective leases and including within indirect hotel operating expenses in the consolidated statements of operations. On July 29, 2014, the Trust terminated one of the two ground leases with below market terms in connection with acquiring the associated land parcel and recognized a $1.2 million loss on impairment of intangible asset, which is included within indirect hotel operating expenses in the consolidated statement of operations for the year ended December 31, 2014. Also in conjunction with the acquisition of the Denver Marriott City Center, the Trust assumed a management contract with a non-cancelable term ending December 2047. The Trust concluded that the management agreement terms were above market terms and recorded a $14.2 million unfavorable contract liability, which the Trust is amortizing over the remaining non-cancelable term and including within indirect hotel operating expenses in the consolidated statements of operations.

	-1	The Trust may exercise an option to extend the maturity by one year, subject to certain customary conditions. As of December 31, 2014, the interest rate in effect was 1.92%. See below for additional information related to the revolving credit facility.
	-2	At origination, $25.0 million was advanced by the lender and was secured by the Hyatt Herald Square New York. On March 14, 2013, $35.0 million was advanced by the lender in connection with the acquisition of the Hyatt Place New York Midtown South. Following the subsequent advance, the entire $60.0 million principal amount of the loan was secured by both hotels. The loan bore interest equal to LIBOR plus 3.25%. Contemporaneous with the origination of the term loan, the Trust entered into an interest rate swap to effectively fix the interest rate on the initial $25.0 million advance for the original two-year term at 3.75% per annum. Under the terms of this interest rate swap, the Trust paid fixed interest of 0.50% per annum on a notional amount of $25.0 million and received floating rate interest equal to the one-month LIBOR. The effective date of this interest rate swap was July 3, 2012 and it matured on July 3, 2014. Contemporaneous with the subsequent advance, the Trust entered into an interest rate swap to effectively fix the interest rate on the $35.0 million subsequent advance for the remaining initial term of the loan at 3.65% per annum. Under the terms of this interest rate swap, the Trust paid fixed interest of 0.40% per annum on a notional amount of $35.0 million and received floating rate interest equal to the one-month LIBOR. The effective date of this interest rate swap was March 14, 2013 and it matured on July 3, 2014. The Trust repaid the term loan at maturity on July 3, 2014.
	-3	On June 30, 2011, in connection with the acquisition of the Courtyard Washington Capitol Hill/Navy Yard, the Trust assumed an existing loan agreement with an outstanding principal balance of $37.5 million. Based on interest rates on similar types of debt instruments at the time of assumption, the Trust recorded the loan at its estimated fair value of $38.6 million, which included a premium on mortgage loan of $1.1 million. Amortization of premium on mortgage loan is computed using a method that approximates the effective interest method over the term of the loan agreement and is included in interest expense in the consolidated statements of operations.
	-4	The loan has a term of 30 years, but is callable by the lender after 10 years, and the Trust expects the lender to call the loan at that time. The indicated maturity is based on the date the loan is callable by the lender.
	-5	The loan requires interest-only payments for the first two years and principal and interest payments thereafter.
