Accounting Policies [Abstract]
Summary of Significant Accounting Policies	s Overview Healthcare Realty Trust Incorporated (the “Company”) is a real estate investment trust ("REIT") 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. As of June 30, 2016 , the Company had investments of approximately $3.4 billion in 202 real estate properties located in 30 states totaling approximately 14.5 million square feet. The Company provided leasing and property management services to approximately 10.0 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, 2015 . All material intercompany transactions and balances have been eliminated in consolidation. This interim financial information should be read in conjunction with the financial statements included in this report and in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 . 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, 2016 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. New Accounting Pronouncements Accounting Standards Update No. 2014-09 and No. 2015-14 In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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 other standards. In August 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers (Topic 606); Deferral of the Effective Date." This standard is effective for the Company for annual and interim periods beginning after December 15, 2017 with early adoption permitted only as of annual reporting periods beginning after December 15, 2016, including interim periods within that year. The Company is currently evaluating the impact from the adoption of this new standard on the Consolidated Financial Statements and related notes. Accounting Standards Update No. 2015-03 In April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs." This standard required debt issuance costs to be reported in the balance sheet as a direct reduction from the face amount of the note to which it is directly related. In August 2015, the FASB issued ASU No. 2015-15, "Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements," which allowed entities to defer and present debt issuance costs related to line-of-credit arrangements as assets regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The Company adopted this standard as of January 1, 2016. As a result of the adoption all deferred financing costs, excluding costs related to the unsecured revolving credit facility, were reclassified to Notes and bonds payable. Unsecured revolving credit facility costs remain classified as an asset and will continue to be amortized over the remaining term. The guidance requires retrospective adoption for all prior periods presented. The following table represents the previously reported balances and reclassified balances for the impacted line items of the Consolidated Balance Sheets as of December 31, 2015 : December 31, 2015 (in thousands) As Previously Reported As Reclassified Other assets, net $ 192,918 $ 186,416 Total assets $ 2,816,726 $ 2,810,224 Notes and bonds payable $ 1,431,494 $ 1,424,992 Total liabilities $ 1,573,979 $ 1,567,477 Total liabilities and stockholders' equity $ 2,816,726 $ 2,810,224 Accounting Standards Update No. 2015-16 In September 2015, the FASB issued ASU No. 2015-16, "Simplifying the Accounting for Measurement-Period Adjustments." This standard requires adjustments to provisional amounts that are identified during the measurement period after a business combination to be recognized in the reporting period in which the adjustment amounts are determined. The adjustments recognized in the current period include the effects on earnings of changes in depreciation, amortization, or other income effects as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The Company adopted this standard effective as of January 1, 2016. The adoption of this standard had no impact on the Company's consolidated financial position or cash flows. Accounting Standards Update No. 2016-02 In February 2016, the FASB issued ASU No. 2016-02, "Leases." For lessees, the new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. For lessors, the new standard requires a lessor to classify leases as either sales-type, finance or operating. A lease will be treated as a sale if it transfers all of the risks and rewards, as well as control of the underlying asset, to the lessee. If risks and rewards are conveyed without the transfer of control, the lease is treated as financing. If the lessor doesn't convey risks and rewards or control, an operating lease results. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessors for sales-type, direct financing, and operating existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact from the adoption of this new standard on the Consolidated Financial Statements and related notes. Accounting Standards Update No. 2016-09 In March 2016, the FASB issued ASU No. 2016-09, "Compensation - Stock Compensation; Improvements to Employee Share-Based Payment Accounting." This update was issued as part of the simplification initiative. The areas of simplification relevant to the Company include the following: • Forfeitures - an entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. • Minimum statutory tax withholding requirements - the threshold to qualify for equity classification permits withholding up to the maximum statutory tax rates in the applicable jurisdiction. • Classification of employee taxes paid on the Statement of Cash Flows when an employer withholds shares for tax-withholding purposes - cash paid by an employer when directly withholding shares for tax-withholding purposes should be classified as a financing activity. This standard is effective for the Company for annual and interim periods beginning on January 1, 2017 with early adoption permitted. The Company adopted this standard effective January 1, 2016. There was no impact to the Company's Condensed Consolidated Financial Statements resulting from the adoption of this standard.

On February 11, 2016, the Company repaid in full a mortgage note payable bearing interest at a rate of 5.86% with outstanding principal of $10.2 million .

The mortgage note encumbered a 42,957 square foot medical office building located in Virginia. On May 13, 2016, upon acquisition of a 63,012 square foot medical office property in Los Angeles, California, the Company assumed a $13.2 million mortgage note payable (excluding a fair value premium adjustment of $0.8 million). The mortgage note payable has a contractual interest rate of 4.77% (effective rate of 4.13% ). Subsequent Activity With proceeds of the equity offering that the Company completed on July 5, 2016, the Company repaid the outstanding balance of $190.0 million on its unsecured credit facility due 2017 ("Unsecured Credit Facility"). In addition, the Company repaid $50.0 million on its unsecured term loan facility due 2019 ("Unsecured Term Loan") leaving an outstanding balance of $150.0 million with a weighted average interest rate of approximately 1.6% . On July 29, 2016 , the Company entered into an amendment to its Unsecured Credit Facility that extended the maturity date from April 2017 to July 2020 , reduced the spread over LIBOR that the Company pays for borrowing, and revised financial covenants to provide the Company with increased flexibility. Amounts outstanding under the Unsecured Credit Facility bear interest at LIBOR plus an applicable margin rate. The margin rate, which depends on the Company's credit ratings, ranges from 0.83% to 1.55% (currently at 1.00% ). In addition, the Company pays a facility fee per annum on the aggregate amount of commitments ranging from 0.13% to 0.30% (currently at 0.20% ). In connection with the amendment, the Company paid upfront fees to the lenders and other costs of approximately $4.4 million which will be amortized over the term of the Unsecured Credit Facility. As of August 3, 2016, the Company had no borrowings outstanding under the Unsecured Credit Facility and had a remaining borrowing capacity of $700.0 million . On July 29, 2016, the Company also entered into an amendment to the Unsecured Term Loan. This amendment was for the purpose of conforming the financial covenants in the Unsecured Term Loan to those in the amendment to the Unsecured Credit Facility. The amendment did not impact the maturity date or cost of borrowing under the Unsecured Term Loan.

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 on its variable rate debt. 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. As of June 30, 2016 , the Company did not have any outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk. The effective portion of changes in the fair value of derivatives designated as, and that qualify as, cash flow hedges is recorded in accumulated other comprehensive income or loss (“OCI”) and is reclassified into earnings as interest expense in the period that the hedged forecasted transaction affects earnings. The effective portion of the Company’s interest rate swaps that was recorded in the accompanying Condensed Consolidated Statements of Income for the three and six months ended June 30, 2016 and 2015 respectively, was as follows: (Dollars in thousands) Three Months Ended June 30, Six Months Ended June 30, 2016 2015 2016 2015 Amount of gain (loss) recognized in OCI on derivative (effective portion) $ — $ (961 ) $ — $ (1,684 ) Amount of gain (loss) reclassified from accumulated OCI into Interest Expense (effective portion) $ (42 ) $ (31 ) $ (84 ) $ (31 ) Amount of gain (loss) recognized in income on derivative (ineffective portion and amount excluded from effectiveness testing) $ — $ 0 $ — $ 0 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.

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. Borrowings under the unsecured credit facility due 2017 and unsecured term loan due 2019 - The carrying amount approximates fair value because the borrowings are based on variable market 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. The table below details the fair values and carrying values for notes and bonds payable at June 30, 2016 and December 31, 2015 .

Accounting Policies [Abstract]
Business Overview	Business Overview Healthcare Realty Trust Incorporated (the “Company”) is a real estate investment trust ("REIT") 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. As of June 30, 2016 , the Company had investments of approximately $3.4 billion in 202 real estate properties located in 30 states totaling approximately 14.5 million square feet. The Company provided leasing and property management services to approximately 10.0 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, 2015 . All material intercompany transactions and balances have been eliminated in consolidation. This interim financial information should be read in conjunction with the financial statements included in this report and in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 . 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, 2016 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.
New Accounting Pronouncements	New Accounting Pronouncements Accounting Standards Update No. 2014-09 and No. 2015-14 In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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 other standards. In August 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers (Topic 606); Deferral of the Effective Date." This standard is effective for the Company for annual and interim periods beginning after December 15, 2017 with early adoption permitted only as of annual reporting periods beginning after December 15, 2016, including interim periods within that year. The Company is currently evaluating the impact from the adoption of this new standard on the Consolidated Financial Statements and related notes. Accounting Standards Update No. 2015-03 In April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs." This standard required debt issuance costs to be reported in the balance sheet as a direct reduction from the face amount of the note to which it is directly related. In August 2015, the FASB issued ASU No. 2015-15, "Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements," which allowed entities to defer and present debt issuance costs related to line-of-credit arrangements as assets regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The Company adopted this standard as of January 1, 2016. As a result of the adoption all deferred financing costs, excluding costs related to the unsecured revolving credit facility, were reclassified to Notes and bonds payable. Unsecured revolving credit facility costs remain classified as an asset and will continue to be amortized over the remaining term. The guidance requires retrospective adoption for all prior periods presented. The following table represents the previously reported balances and reclassified balances for the impacted line items of the Consolidated Balance Sheets as of December 31, 2015 : December 31, 2015 (in thousands) As Previously Reported As Reclassified Other assets, net $ 192,918 $ 186,416 Total assets $ 2,816,726 $ 2,810,224 Notes and bonds payable $ 1,431,494 $ 1,424,992 Total liabilities $ 1,573,979 $ 1,567,477 Total liabilities and stockholders' equity $ 2,816,726 $ 2,810,224 Accounting Standards Update No. 2015-16 In September 2015, the FASB issued ASU No. 2015-16, "Simplifying the Accounting for Measurement-Period Adjustments." This standard requires adjustments to provisional amounts that are identified during the measurement period after a business combination to be recognized in the reporting period in which the adjustment amounts are determined. The adjustments recognized in the current period include the effects on earnings of changes in depreciation, amortization, or other income effects as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The Company adopted this standard effective as of January 1, 2016. The adoption of this standard had no impact on the Company's consolidated financial position or cash flows. Accounting Standards Update No. 2016-02 In February 2016, the FASB issued ASU No. 2016-02, "Leases." For lessees, the new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. For lessors, the new standard requires a lessor to classify leases as either sales-type, finance or operating. A lease will be treated as a sale if it transfers all of the risks and rewards, as well as control of the underlying asset, to the lessee. If risks and rewards are conveyed without the transfer of control, the lease is treated as financing. If the lessor doesn't convey risks and rewards or control, an operating lease results. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessors for sales-type, direct financing, and operating existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact from the adoption of this new standard on the Consolidated Financial Statements and related notes. Accounting Standards Update No. 2016-09 In March 2016, the FASB issued ASU No. 2016-09, "Compensation - Stock Compensation; Improvements to Employee Share-Based Payment Accounting." This update was issued as part of the simplification initiative. The areas of simplification relevant to the Company include the following: • Forfeitures - an entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. • Minimum statutory tax withholding requirements - the threshold to qualify for equity classification permits withholding up to the maximum statutory tax rates in the applicable jurisdiction. • Classification of employee taxes paid on the Statement of Cash Flows when an employer withholds shares for tax-withholding purposes - cash paid by an employer when directly withholding shares for tax-withholding purposes should be classified as a financing activity. This standard is effective for the Company for annual and interim periods beginning on January 1, 2017 with early adoption permitted. The Company adopted this standard effective January 1, 2016. There was no impact to the Company's Condensed Consolidated Financial Statements resulting from the adoption of this standard.
