Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	Business Overview
	Healthcare Realty Trust Incorporated (the “Company”) is a real estate investment trust that integrates owning, managing, financing and developing income-producing real estate properties associated primarily with the delivery of outpatient healthcare services throughout the United States. The Company had investments of approximately $3.3 billion in 199 real estate properties and mortgages as of March 31, 2015. The Company’s 198 owned real estate properties are located in 30 states and total approximately 14.3 million square feet. The Company provided property management services to approximately 9.5 million square feet nationwide.
	Basis of Presentation
	The Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. They do not include all of the information and footnotes required by GAAP for complete financial statements. However, except as disclosed herein, management believes there has been no material change in the information disclosed in the Notes to Consolidated Financial Statements included in the Annual Report on Form 10-K for the year ended December 31, 2014. All material intercompany transactions and balances have been eliminated in consolidation.
	This interim financial information should be read in conjunction with the financial statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in this report and in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. Management believes that all adjustments of a normal, recurring nature considered necessary for a fair presentation have been included. In addition, the interim financial information does not necessarily represent or indicate what the operating results will be for the year ending December 31, 2015 for many reasons including, but not limited to, acquisitions, dispositions, capital financing transactions, changes in interest rates and the effects of other trends, risks and uncertainties.
	Use of Estimates in the Condensed Consolidated Financial Statements
	Preparation of the Condensed Consolidated Financial Statements in accordance with GAAP requires management to make estimates and assumptions that affect amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. Actual results may differ from those estimates.
	Fair Value of Derivative Financial Instruments
	Derivative financial instruments are recorded at fair value on the Company's Condensed Consolidated Balance Sheets as other assets or other liabilities. The valuation of derivative instruments requires the Company to make estimates and judgments that affect the fair value of the instruments. Fair values of derivatives are estimated by pricing models that consider the forward yield curves and discount rates. The fair value of the Company's forward exchange contracts are estimated by pricing models that consider foreign trade rates and discount rates. Such amounts and the recognition of such amounts are subject to significant estimates that may change in the future. See Note 4 for additional information.
	New Accounting Pronouncements
	Accounting Standards Update No. 2015-03
	In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs." This standard requires debt issuance costs to be reported in the balance sheet as a direct reduction from the face amount of the note in which it is directly related.
	This standard is effective for the Company beginning on January 1, 2016 with early adoption permitted, on a retrospective basis, wherein the balance sheet of each individual period presented should be adjusted to reflect the period-specific effects of applying the new guidance. Upon transition, the Company is required to comply with the applicable disclosures for a change in an accounting principle. The Company does not expect the adoption of this standard to have a material impact on the Company's consolidated financial position or cash flows.
	Accounting Standards Update No. 2014-08
	In April 2014, the FASB issued ASU No. 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” This standard changes the requirements for reporting discontinued operations by raising the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations, and certain other disposals that do not meet the definition of a discontinued operation. The standard limits discontinued operations reporting to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on an entity’s operations and financial results.
	This standard is effective for the Company on a prospective basis for annual periods beginning on January 1, 2015 and interim periods within that year. Early adoption was permitted but only for disposals (or classifications as held for sale) that had not been reported in financial statements previously issued. The Company adopted this standard on the effective date of January 1, 2015 and does not expect it to have a material impact on the Company's consolidated financial position or cash flows, but it could have a material impact on the presentation of the Consolidated Statement of Operations.
	Accounting Standards Update No. 2014-09
	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers", a comprehensive new revenue recognition standard that supersedes most existing revenue recognition guidance, including sales of real estate. This standard's core principle is that a company will recognize revenue when it transfers goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods and services. However, leasing contracts, representing the major source of the Company's revenues, are not within the scope of the new standard and will continue to be accounted for under existing standards.
	This new standard is effective for the Company for annual and interim periods beginning on January 1, 2017 with early adoption prohibited. However, the FASB issued an exposure draft on April 29, 2015 that would defer the effective date one year. The Company has not yet determined the effects on the Consolidated Financial Statements and related notes resulting from the adoption of this new standard.
	Reclassifications
	Certain amounts in the Company’s Condensed Consolidated Balance Sheets have been reclassified for the current period presentation of assets held for sale and related liabilities.

	2015 Acquisition
	In January 2015, the Company acquired a 110,679 square foot medical office building in California for a purchase price and cash consideration of $39.3 million. The property is located adjacent to two hospital campuses, Kaiser Permanente, a 106-bed hospital, and Washington Hospital Healthcare System, a 353-bed hospital. Upon acquisition, this property was 97% leased, with leases to the two hospitals comprising 59% of the rentable square footage.
	Assets Held for Sale
	During the first quarter of 2015, the Company reclassified one off-campus medical office building to held for sale in connection with management's decision to sell the property. The Company expects that the property will be sold during 2015. The Company recorded an impairment charge of $3.3 million to record the property at estimated fair value less costs to sell, which was based on a purchase and sale agreement, a level 3 input, that was subsequently terminated. At March 31, 2015 and December 31, 2014, the Company had three and two properties classified as held for sale, respectively.
	The table below reflects the assets and liabilities of the properties classified as held for sale as of March 31, 2015 and December 31, 2014.

	Discontinued Operations
	The Company adopted Accounting Standards Update No. 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity” during the first quarter of 2015. As of December 31, 2014, the Company had two properties classified as held for sale and recorded in discontinued operations. These two properties will remain classified as discontinued operations until the properties are sold. During the three months ended March 31, 2015, the Company reclassified a property to held for sale upon management's decision to sell the property that did not meet the amended criteria as a discontinued operation. Therefore, the operating results of the property is not included in the table below which reflects the results of operations of the properties included in discontinued operations on the Company's Condensed Consolidated Statements of Operations for the three months ended March 31, 2015 and 2014.

	First Quarter
	In January 2015, the Company repaid in full a secured loan from Wells Fargo Commercial Mortgage bearing an interest rate of 5.45% consisting of outstanding principal of $15.0 million and accrued interest as of the redemption date of $0.1 million.
	Subsequent Activity
	On April 1, 2015, the Company repaid in full a secured loan from Wells Fargo Commercial Mortgage bearing an interest rate of 5.0% consisting of principal of $10.2 million.
	On April 24, 2015, the Company issued $250.0 million of unsecured senior notes due 2025 (the "Senior Notes due 2025") in a registered public offering. The Senior Notes due 2025 bear interest at 3.875%, payable semi-annually on May 1 and November 1, beginning November 1, 2015, and are due on May 1, 2025, unless redeemed earlier by the Company. The notes were issued at a discount of approximately $0.2 million, which yielded a 3.885% interest rate per annum upon issuance. The Company incurred approximately $2.1 million in debt issuance costs that are included in Other assets, which will be amortized to maturity using the effective interest method. See Note 4 for discussion regarding the concurrent termination of the four forward starting interest rate swaps and related impact. The Senior Notes due 2025 have various financial covenants that are required to be met on a quarterly and annual basis.
	Also in April 2015, the Company issued a notice of its intent to redeem its unsecured senior notes due 2017 on May 15, 2015 at a redemption price equal to an aggregate of $333.2 million, consisting of outstanding principal of $300.0 million, accrued interest of $6.4 million, and a "make-whole" amount of approximately $26.8 million for the early extinguishment of debt. The unaccreted discount and unamortized costs on these notes of $1.2 million will be written off upon redemption. In the second quarter of 2015, the Company expects to recognize a loss on early extinguishment of debt of approximately $28.0 million related to this redemption.
	On May 4, 2015, the Company repaid in full a mortgage note payable bearing an interest rate of 5.41% consisting of outstanding principal of $16.3 million and accrued interest as of the redemption date of $0.1 million.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Financial Instruments
	Risk Management Objective of Using Derivatives
	In addition to operational risks which arise in the normal course of business, the Company is exposed to economic risks such as interest rate, liquidity, and credit risk. In certain situations, the Company may enter into derivative financial instruments such as interest rate swap and interest rate cap agreements to manage interest rate risk exposure arising from variable rate debt transactions that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company's objective in using interest rate derivatives is to manage its exposure to interest rate movements.
	Cash Flow Hedges of Interest Rate Risk
	Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without changing the underlying notional amount.
	During the three months ended March 31, 2015, the Company entered into two forward starting interest rate swaps with a total notional value of $125.0 million to hedge the risk of changes in the interest-related cash flows associated with the potential issuance of long-term debt that was issued in April 2015 as discussed in Note 3. The Company was hedging its exposure to the variability in future cash flows for forecasted transactions. As of March 31, 2015, the Company had hedged $125.0 million associated with the potential incurrence of long-term debt.
	A detail of the Company's interest rate derivatives outstanding as of March 31, 2015 is as follows (in thousands):
	Interest Rate Derivative	Notional Amount
	Interest Rate Swaps	$	125,000
	The Company has elected to present its interest rate derivatives on its Condensed Consolidated Balance Sheets on a gross basis as interest rate swap assets and interest rate swap liabilities. A detail of the Company's fair value of interest rate derivatives on a gross and net basis as of March 31, 2015 is as follows (in thousands):
	Interest Rate Swaps Classified as:	Fair Value of Derivative Instruments
	Gross derivative liabilities	$	(723	)
	Derivative liability	$	(723	)
	All of the Company's interest rate swap agreements outstanding for the three months ended March 31, 2015 were designated as cash flow hedges of interest rate risk. The effective portion of the changes in fair value of derivatives designated as, and that qualify as, cash flow hedges is recorded in other comprehensive income (loss) ("OCI") and will be reclassified into earnings as interest expense in the period that the hedged forecasted transaction affects earnings.
	The following presents the impacts of derivative instruments on the Condensed Consolidated Statements of Comprehensive Income for the three months ended March 31, 2015 (in thousands):
		Location		For the Three Months Ended March 31, 2015
	Loss on forward starting interest rate swap agreements recognized in OCI	OCI		$	723
	The Company estimates that an additional $0.2 million will be reclassified from accumulated other comprehensive loss as an increase to interest expense over the next 12 months. No gain or loss was recognized related to hedge ineffectiveness or to amounts excluded from effectiveness testing on the Company's cash flow hedges during the three months ended March 31, 2015.
	Credit-risk-related Contingent Features
	The Company has agreements with its derivative counterparties that contain a provision whereby if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. If the Company were to breach any of the contractual provisions of the derivative contracts, it would be required to settle its obligations under the agreements at their termination value including accrued interest, or approximately $0.7 million at March 31, 2015. Additionally, the Company does have rights of set-off under certain of its derivative agreements related to potential termination fees and amounts payable under the agreements, if a termination were to occur.
	Subsequent Activity
	On April 1 and April 3, 2015, the Company entered into two forward starting swap agreements with a total notional value of $62.5 million and $37.5 million, respectively.
	On April 24, 2015 and in conjunction with the Company's issuance of the Senior Notes due 2025, the Company settled the four previously outstanding forward starting swap agreements for a loss of approximately $1.7 million. The loss was recorded as accumulated other comprehensive income and is being amortized as additional interest expense over the ten-year term of the Senior Notes due 2025 resulting in an effective interest rate of 3.97%. The Company classifies cash flows from the settlement of hedging derivative instruments in the same category as the underlying exposure which is being hedged. As the cash settlement of approximately $1.7 million was the result of hedging the Company's exposure to interest rate changes and their effect on interest expense, such cash settlement is classified as an operating cash flow in the accompanying consolidated statements of cash flows. See Note 3 for more information on the bond issuance.

The total estimated budget of the redevelopment of these properties is expected to be $47.8 million and the project is expected to be completed near the end of 2016.
	The Company will commence redevelopment of a property in Alabama, which will include building a parking garage. Construction is expected to begin in the second quarter of 2015. The total redevelopment budget is $15.4 million, of which $1.5 million has been spent as of March 31, 2015. Construction is expected to be completed at the beginning of 2016.

Defined Benefit Pension Plan	Defined Benefit Pension Plan
	The Company’s Executive Retirement Plan provides benefits upon retirement for three of the Company’s founding officers. The plan is unfunded and benefits will be paid from cash flows of the Company. The maximum annual benefits payable to each individual under the Executive Retirement Plan is $0.9 million, subject to cost-of-living adjustments. As of March 31, 2015, only the Company’s Chief Executive Officer was eligible to retire under the Executive Retirement Plan.
	Net periodic benefit cost recorded related to the Company’s pension plan for the three months ended March 31, 2015 and 2014 is detailed in the following table.
		Three Months Ended March 31,

	Total recognized in net periodic benefit cost	$	299		$	14
	Subsequent Activity
	Effective May 5, 2015, the Company terminated its Executive Retirement Plan. The Company will settle benefits under the plan by paying the plan participants lump sum amounts. In accordance with Section 409A of the Internal Revenue Code, these amounts will be paid no earlier than twelve and no later than twenty-four months following the termination date. The Second Amendment to the Second Amended and Restated Executive Retirement Plan (the “Termination Amendment”), which provides for the termination of the plan, is filed with this Quarterly Report on Form 10-Q as Exhibit 10.1. Additional information regarding the Executive Retirement Plan can be found in the Company’s proxy statement filed with the Securities and Exchange Commission in connection with the Company’s annual meeting of shareholders to be held on May 12, 2015.
	At March 31, 2015, the Company recognized a total benefit obligation of $16.8 million in connection with the Executive Retirement Plan. The Company expects the total costs associated with the termination of the Executive Retirement Plan to be approximately $19.6 million and that it will record a current period charge in the second quarter of 2015 of approximately $5.3 million, inclusive of the acceleration of $2.5 million recorded in accumulated other comprehensive income (loss) on the consolidated balance sheet that was being amortized. The charge includes amounts resulting from assumed additional years of service for plan participants who have not reached age 65 and payments associated with FICA and other tax obligations.
	The Company’s chairman and chief executive officer, Mr. David Emery, is the only named executive officer that is a participant under the plan. As a result of the termination, Mr. Emery will receive a lump sum amount equal to his accrued benefit under the plan of approximately $14.4 million. The Company expects that Mr. Emery and the other officer participants will take the settlement payments in Company stock, but can elect to receive cash.
	The preceding summary is qualified in its entirety by the full text of the Termination Amendment and, in the event of any discrepancy, the text of the Termination Amendment shall control.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments
	The following methods and assumptions were used to estimate the fair value of each class of financial instrument for which it is practical to estimate that value.
	Cash and cash equivalents - The carrying amount approximates fair value.
	Mortgage notes receivable - The fair value of mortgage notes receivable is estimated based either on cash flow analyses at an assumed market rate of interest or at a rate consistent with the rates on mortgage notes acquired by the Company recently.
	Borrowings under the unsecured credit facility due 2017 - The carrying amount approximates fair value because the borrowings are based on variable interest rates.
	Senior unsecured notes payable - The fair value of notes and bonds payable is estimated using cash flow analyses, based on the Company’s current interest rates for similar types of borrowing arrangements.
	Mortgage notes payable - The fair value is estimated using cash flow analyses, based on the Company’s current interest rates for similar types of borrowing arrangements.
	Interest rate swap agreements - Interest rate swap agreements are recorded in other liabilities on the Company's Condensed Consolidated Balance Sheets at fair value. Fair value is estimated by utilizing pricing models that consider forward yield curves and discount rates.
	The table below details the fair values and carrying values for notes and bonds payable, mortgage notes receivable and interest rate swaps at March 31, 2015 and December 31, 2014.
		March 31, 2015				December 31, 2014

	(1) Level 3 - Fair value derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.
	(2) Level 2 - Fair value based on quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which significant inputs and significant value drivers are observable in active markets.

Accounting Policies [Abstract]
Business Overview	Business Overview
	Healthcare Realty Trust Incorporated (the “Company”) is a real estate investment trust that integrates owning, managing, financing and developing income-producing real estate properties associated primarily with the delivery of outpatient healthcare services throughout the United States. The Company had investments of approximately $3.3 billion in 199 real estate properties and mortgages as of March 31, 2015. The Company’s 198 owned real estate properties are located in 30 states and total approximately 14.3 million square feet. The Company provided property management services to approximately 9.5 million square feet nationwide.
Basis of Presentation	Basis of Presentation
	The Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. They do not include all of the information and footnotes required by GAAP for complete financial statements. However, except as disclosed herein, management believes there has been no material change in the information disclosed in the Notes to Consolidated Financial Statements included in the Annual Report on Form 10-K for the year ended December 31, 2014. All material intercompany transactions and balances have been eliminated in consolidation.
	This interim financial information should be read in conjunction with the financial statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in this report and in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. Management believes that all adjustments of a normal, recurring nature considered necessary for a fair presentation have been included. In addition, the interim financial information does not necessarily represent or indicate what the operating results will be for the year ending December 31, 2015 for many reasons including, but not limited to, acquisitions, dispositions, capital financing transactions, changes in interest rates and the effects of other trends, risks and uncertainties.
Use of Estimates in the Condensed Consolidated Financial Statements	Use of Estimates in the Condensed Consolidated Financial Statements
	Preparation of the Condensed Consolidated Financial Statements in accordance with GAAP requires management to make estimates and assumptions that affect amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. Actual results may differ from those estimates.
Fair Value of Derivative Instruments	Fair Value of Derivative Financial Instruments
	Derivative financial instruments are recorded at fair value on the Company's Condensed Consolidated Balance Sheets as other assets or other liabilities. The valuation of derivative instruments requires the Company to make estimates and judgments that affect the fair value of the instruments. Fair values of derivatives are estimated by pricing models that consider the forward yield curves and discount rates. The fair value of the Company's forward exchange contracts are estimated by pricing models that consider foreign trade rates and discount rates. Such amounts and the recognition of such amounts are subject to significant estimates that may change in the future.
New Accounting Pronouncements	New Accounting Pronouncements
	Accounting Standards Update No. 2015-03
	In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs." This standard requires debt issuance costs to be reported in the balance sheet as a direct reduction from the face amount of the note in which it is directly related.
	This standard is effective for the Company beginning on January 1, 2016 with early adoption permitted, on a retrospective basis, wherein the balance sheet of each individual period presented should be adjusted to reflect the period-specific effects of applying the new guidance. Upon transition, the Company is required to comply with the applicable disclosures for a change in an accounting principle. The Company does not expect the adoption of this standard to have a material impact on the Company's consolidated financial position or cash flows.
	Accounting Standards Update No. 2014-08
	In April 2014, the FASB issued ASU No. 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” This standard changes the requirements for reporting discontinued operations by raising the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations, and certain other disposals that do not meet the definition of a discontinued operation. The standard limits discontinued operations reporting to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on an entity’s operations and financial results.
	This standard is effective for the Company on a prospective basis for annual periods beginning on January 1, 2015 and interim periods within that year. Early adoption was permitted but only for disposals (or classifications as held for sale) that had not been reported in financial statements previously issued. The Company adopted this standard on the effective date of January 1, 2015 and does not expect it to have a material impact on the Company's consolidated financial position or cash flows, but it could have a material impact on the presentation of the Consolidated Statement of Operations.
	Accounting Standards Update No. 2014-09
	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers", a comprehensive new revenue recognition standard that supersedes most existing revenue recognition guidance, including sales of real estate. This standard's core principle is that a company will recognize revenue when it transfers goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods and services. However, leasing contracts, representing the major source of the Company's revenues, are not within the scope of the new standard and will continue to be accounted for under existing standards.
	This new standard is effective for the Company for annual and interim periods beginning on January 1, 2017 with early adoption prohibited. However, the FASB issued an exposure draft on April 29, 2015 that would defer the effective date one year. The Company has not yet determined the effects on the Consolidated Financial Statements and related notes resulting from the adoption of this new standard.
