Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Significant Accounting Policies	Description of Business and Significant Accounting Policies Description of Business Highwoods Properties, Inc. (the “Company”) is a fully integrated real estate investment trust (“REIT”) that provides leasing, management, development, construction and other customer-related services for its properties and for third parties. The Company conducts its activities through Highwoods Realty Limited Partnership (the “Operating Partnership”). At September 30, 2020, we owned or had an interest in 27.9 million rentable square feet of in-service properties, 1.2 million rentable square feet of office properties under development and approximately 225 acres of development land. The Company is the sole general partner of the Operating Partnership. At September 30, 2020, the Company owned all of the Preferred Units and 103.5 million, or 97.3%, of the Common Units in the Operating Partnership. Limited partners owned the remaining 2.8 million Common Units. During the nine months ended September 30, 2020, the Company issued 118,592 Common Units to acquire real estate assets. Basis of Presentation Our Consolidated Financial Statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company’s Consolidated Financial Statements include the Operating Partnership, wholly owned subsidiaries and those entities in which the Company has the controlling interest. The Operating Partnership’s Consolidated Financial Statements include wholly owned subsidiaries and those entities in which the Operating Partnership has the controlling interest. We consolidate joint venture investments, such as interests in partnerships and limited liability companies, when we control the major operating and financial policies of the investment through majority ownership, in our capacity as a general partner or managing member or through some other contractual right. We also consolidate those entities deemed to be variable interest entities in which we are determined to be the primary beneficiary. At September 30, 2020, we have involvement with, and are the primary beneficiary in, an entity that we concluded to be a variable interest entity (see Note 3). All intercompany transactions and accounts have been eliminated. The unaudited interim consolidated financial statements and accompanying unaudited consolidated financial information, in the opinion of management, contain all adjustments (including normal recurring accruals) necessary for a fair presentation of our financial position, results of operations and cash flows. We have condensed or omitted certain notes and other information from the interim Consolidated Financial Statements presented in this Quarterly Report as permitted by SEC rules and regulations. These Consolidated Financial Statements should be read in conjunction with our 2019 Annual Report on Form 10-K. Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in our Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates. Insurance We are primarily self-insured for health care claims for participating employees. We have stop-loss coverage to limit our exposure to significant claims on a per claim and annual aggregate basis. We determine our liabilities for claims, including incurred but not reported losses, based on all relevant information, including actuarial estimates of claim liabilities. At September 30, 2020, a reserve of $0.5 million was recorded to cover estimated reported and unreported claims. Recently Issued Accounting Standards The Financial Accounting Standards Board (“FASB”) issued an accounting standards update (“ASU”) that changes certain disclosure requirements for fair value measurements. We adopted the ASU as of January 1, 2020 with no material effect on our Notes to Consolidated Financial Statements. The FASB issued an ASU that provides temporary optional expedients and exceptions to the guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from LIBOR and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (“SOFR”). Entities can elect not to apply certain modification accounting requirements to contracts affected by reference rate reform, if certain criteria are met. An entity that makes this election would not have to remeasure the contracts at the modification date or reassess a previous accounting determination. Entities can also elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met. The guidance in this ASU is optional and may be elected over the period March 12, 2020 through December 31, 2022 as reference rate reform activities occur. We will continue to evaluate the impact of this ASU; however, we currently expect to avail ourselves of such optional expedients and exceptions should our modified contracts meet the required criteria. Due to the business disruptions and challenges severely affecting the global economy caused by the COVID-19 pandemic, lessors may provide rent deferrals and other lease concessions to lessees. In April 2020, the FASB staff issued a question and answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance to lease concessions provided as a result of the COVID-19 pandemic. Under existing lease guidance, we would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant (treated within the lease modification accounting framework) or if a lease concession was under the enforceable rights and obligations within the existing lease agreement (precluded from applying the lease modification accounting framework). The Lease Modification Q&A allows us, if certain criteria have been met, to bypass the lease by lease analysis, and instead elect to either apply the lease modification accounting framework or not, with such election applied consistently to leases with similar characteristics and similar circumstances. We have elected the practical expedient and will not apply lease modification accounting on a lease by lease basis where applicable. As a result, $6.0 million of deferred rent is included in accounts receivable on our Consolidated Balance Sheets at September 30, 2020.

Variable Interest Entities [Abstract]
Consolidated Variable Interest Entity	Consolidated Variable Interest EntityIn 2019, we and The Bromley Companies formed a joint venture (the “Midtown One joint venture”) to construct Midtown West, a 150,000 square foot, multi-customer office building located in the mixed-use Midtown Tampa project in Tampa’s Westshore submarket. Midtown West has an anticipated total investment of $71.3 million. Construction of Midtown West began in the third quarter of 2019 with a scheduled completion date in the second quarter of 2021. At closing, we agreed to contribute cash of $20.0 million, which has been fully funded, in exchange for an 80.0% interest in the Midtown One joint venture and The Bromley Companies contributed land valued at $5.0 million in exchange for the remaining 20.0% interest. We also committed to provide a $46.3 million interest-only secured construction loan to the Midtown One joint venture that is scheduled to mature on the second anniversary of completion. The loan bears interest at LIBOR plus 250 basis points. As of September 30, 2020, $13.7 million under the loan has been funded. We determined that we have a variable interest in the Midtown One joint venture primarily because the entity was designed to pass along interest rate risk, equity price risk and operation risk to us as both a debt and an equity holder and The Bromley Companies as an equity holder. The Midtown One joint venture was further determined to be a variable interest entity as it requires additional subordinated financial support in the form of a loan because the initial equity investment provided by us and The Bromley Companies is not sufficient to finance its planned investments and operations. We, as majority owner and managing member and through our control rights as set forth in the joint venture’s governance documents, were determined to be the primary beneficiary as we have both the power to direct the activities that most significantly affect the entity (primarily lease rates, property operations and capital expenditures) and significant economic exposure through our equity investment and loan commitment. As such, the Midtown One joint venture is consolidated and all intercompany transactions and accounts are eliminated. The following table sets forth the assets and liabilities of the Midtown One joint venture included on our Consolidated Balance Sheets: September 30, Development in-process $ 42,015 Accounts payable, accrued expenses and other liabilities $ 2,706 The assets of the Midtown One joint venture can be used only to settle obligations of the joint venture and its creditors have no recourse to our wholly owned assets.

Real Estate [Abstract]
Real Estate Assets	Real Estate Assets Acquisitions During the second quarter of 2020, we acquired development land in Raleigh for a purchase price, including capitalized acquisition costs, of $2.3 million. During the first quarter of 2020, we acquired development land in Nashville for a purchase price of $6.2 million, which consisted of the issuance of 118,592 Common Units and capitalized acquisition costs. Dispositions During the third quarter of 2020, we sold two buildings in Memphis for an aggregate sale price of $23.3 million and recorded aggregate gains on disposition of property of $9.4 million. During the third quarter of 2020, we also recognized $0.6 million of aggregate gains related to the disposition of property in the first quarter of 2020. During the second quarter of 2020, we sold land in Atlanta for a sale price of $2.8 million and recorded a loss on disposition of property of $0.1 million. During the second quarter of 2020, we also recognized $0.4 million of gain related to the satisfaction of a performance obligation as part of a 2016 land sale. During the first quarter of 2020, we sold 41 buildings and land in Greensboro and Memphis for an aggregate sale price of $338.4 million (before closing credits to buyer of $3.8 million) and recorded aggregate gains on disposition of property of $153.1 million. Impairments During the second quarter of 2020, we recorded an impairment of real estate assets of $1.8 million, which resulted from a change in market-based inputs and our assumptions about the use of the assets.

Our $600.0 million unsecured revolving credit facility is scheduled to mature in January 2022 and includes an accordion feature that allows for an additional $400.0 million of borrowing capacity subject to additional lender commitments. Assuming no defaults have occurred, we have an option to extend the maturity for two additional six During the third quarter of 2020, the Operating Partnership issued $400.0 million aggregate principal amount of 2.600% notes due February 2031, less original issuance discount of $1.6 million. These notes were priced to yield 2.645%. Underwriting fees and other expenses were incurred that aggregated $3.4 million; these costs were deferred and will be amortized over the term of the notes. The net proceeds from the issuance were used: (1) to finance the Operating Partnership’s cash tender offer to purchase $150.0 million principal amount of its 3.20% notes due June 15, 2021 at a purchase price of 101.908% of the face amount of the notes, plus accrued and unpaid interest; (2) to prepay without penalty our $100.0 million unsecured bank term loan that was scheduled to mature in January 2022 and which bore interest at LIBOR plus 110 basis points; and (3) for general corporate purposes. We recorded $3.7 million of aggregate losses on debt extinguishment related to the repurchase of the 3.20% notes and the term loan prepayment. We are currently in compliance with financial covenants with respect to our consolidated debt. We have considered our short-term liquidity needs within one year from October 27, 2020 (the date of issuance of the quarterly financial statements) and the adequacy of our estimated cash flows from operating activities and other available financing sources to meet these needs. In particular, we have considered our scheduled debt maturities during such one-year period, including the $150.0 million principal amount of unsecured notes due June 15, 2021. We have concluded it is probable we will meet these short-term liquidity requirements through a combination of the following: • available cash and cash equivalents; • cash flows from operating activities; • issuance of debt securities by the Operating Partnership; • issuance of secured debt; • bank term loans; • borrowings under our revolving credit facility; • issuance of equity securities by the Company or the Operating Partnership; and • the disposition of non-core assets.

The swap agreements contain a provision whereby if we default on certain of our indebtedness and which default results in repayment of such indebtedness being, or becoming capable of being, accelerated by the lender, then we could also be declared in default on our swaps. Our interest rate swaps have been designated as and are being accounted for as cash flow hedges with changes in fair value recorded in other comprehensive income/(loss) each reporting period. We have no collateral requirements related to our interest rate swaps. Amounts reported in accumulated other comprehensive income/(loss) related to derivatives will be reclassified to interest expense as interest payments are made on our debt.

Fair Value Disclosures [Abstract]
Disclosure About Fair Value of Financial Instruments	Disclosure About Fair Value of Financial Instruments The following summarizes the levels of inputs that we use to measure fair value. Level 1. Quoted prices in active markets for identical assets or liabilities. Our Level 1 asset is our investment in marketable securities that we use to pay benefits under our non-qualified deferred compensation plan. Our Level 1 liability is our non-qualified deferred compensation obligation. The Company’s Level 1 noncontrolling interests in the Operating Partnership relate to the ownership of Common Units by various individuals and entities other than the Company. Level 2. Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities. Our Level 2 assets include the fair value of our mortgages and notes receivable. Our Level 2 liabilities include the fair value of our mortgages and notes payable and interest rate swaps. The fair value of mortgages and notes receivable and mortgages and notes payable is estimated by the income approach utilizing contractual cash flows and market-based interest rates to approximate the price that would be paid in an orderly transaction between market participants. The fair value of interest rate swaps is determined using the market standard methodology of netting the discounted future fixed cash receipts and the discounted expected variable cash payments. The variable cash payments of interest rate swaps are based on the expectation of future interest rates (forward curves) derived from observed market interest rate curves. In addition, credit valuation adjustments are considered in the fair values to account for potential nonperformance risk, but were concluded to not be significant inputs to the calculation for the periods presented. Level 3. Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Our Level 3 assets include any real estate assets recorded at fair value on a non-recurring basis as a result of our quarterly impairment analysis, which are valued using unobservable local and national industry market data such as comparable sales, appraisals, brokers’ opinions of value and/or the terms of definitive sales contracts. Significant increases or decreases in any valuation inputs in isolation would result in a significantly lower or higher fair value measurement. The following table sets forth our assets and liabilities and the Company’s noncontrolling interests in the Operating Partnership that are measured or disclosed at fair value within the fair value hierarchy: Level 1 Level 2 Total Quoted Prices Significant Observable Inputs Fair Value at September 30, 2020: Assets: Mortgages and notes receivable, at fair value (1) $ 1,390 $ — $ 1,390 Marketable securities of non-qualified deferred compensation plan (in prepaid expenses and other assets) 2,259 2,259 — Total Assets $ 3,649 $ 2,259 $ 1,390 Noncontrolling Interests in the Operating Partnership $ 95,416 $ 95,416 $ — Liabilities: Mortgages and notes payable, net, at fair value (1) $ 2,601,035 $ — $ 2,601,035 Interest rate swaps (in accounts payable, accrued expenses and other liabilities) 1,036 — 1,036 Non-qualified deferred compensation obligation (in accounts payable, accrued expenses and other liabilities) 2,259 2,259 — Total Liabilities $ 2,604,330 $ 2,259 $ 2,602,071 Fair Value at December 31, 2019: Assets: Mortgages and notes receivable, at fair value (1) $ 1,501 $ — $ 1,501 Marketable securities of non-qualified deferred compensation plan (in prepaid expenses and other assets) 2,345 2,345 — Total Assets $ 3,846 $ 2,345 $ 1,501 Noncontrolling Interests in the Operating Partnership $ 133,216 $ 133,216 $ — Liabilities: Mortgages and notes payable, net, at fair value (1) $ 2,615,776 $ — $ 2,615,776 Interest rate swaps (in accounts payable, accrued expenses and other liabilities) 154 — 154 Non-qualified deferred compensation obligation (in accounts payable, accrued expenses and other liabilities) 2,345 2,345 — Total Liabilities $ 2,618,275 $ 2,345 $ 2,615,930 __________ (1) Amounts are not recorded at fair value on our Consolidated Balance Sheets at September 30, 2020 and December 31, 2019. The Level 3 impaired real estate assets measured at a fair value of $2.1 million in the second quarter of 2020 included a non-core office building. The impairment resulted from a change in our assumptions about the use of the assets and was calculated using brokers’ opinions of value, letters of intent and comparable sales as observable inputs were not available.

Contingencies	ContingenciesSince early March 2020, efforts to slow the spread of the COVID-19 virus have had a significant impact on the U.S. economy. We continue to follow the policies described in Notes 1 and 2 to our Consolidated Financial Statements contained in our 2019 Annual Report on Form 10-K, including those related to impairments of real estate assets and investments in unconsolidated affiliates, leases and estimates of credit losses on operating lease receivables. While the results of our current analyses did not result in any material adjustments to amounts as of September 30, 2020 and during the three and nine months ended September 30, 2020, circumstances related to the COVID-19 pandemic may result in recording impairments, lease modifications and credit losses in future periods.

Subsequent Events	Subsequent Events On October 1, 2020, we sold a building in Greensboro for a sale price of $4.6 million and expect to record a gain on disposition of property of $1.3 million. On October 15, 2020, the Company declared a cash dividend of $0.48 per share of Common Stock, which is payable on December 8, 2020 to stockholders of record as of November 16, 2020. See also Note 15 for information regarding the potential impact of the COVID-19 pandemic in future periods. The severity and duration of the COVID-19 pandemic and the resulting economic recession and the future demand for office space over the long-term are difficult to predict and could materially and adversely impact or disrupt our financial condition, results of operations, cash flows and performance.

	Sep. 30, 2020
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Our Consolidated Financial Statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company’s Consolidated Financial Statements include the Operating Partnership, wholly owned subsidiaries and those entities in which the Company has the controlling interest. The Operating Partnership’s Consolidated Financial Statements include wholly owned subsidiaries and those entities in which the Operating Partnership has the controlling interest. We consolidate joint venture investments, such as interests in partnerships and limited liability companies, when we control the major operating and financial policies of the investment through majority ownership, in our capacity as a general partner or managing member or through some other contractual right. We also consolidate those entities deemed to be variable interest entities in which we are determined to be the primary beneficiary. At September 30, 2020, we have involvement with, and are the primary beneficiary in, an entity that we concluded to be a variable interest entity (see Note 3). All intercompany transactions and accounts have been eliminated.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in our Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.
Insurance	InsuranceWe are primarily self-insured for health care claims for participating employees. We have stop-loss coverage to limit our exposure to significant claims on a per claim and annual aggregate basis. We determine our liabilities for claims, including incurred but not reported losses, based on all relevant information, including actuarial estimates of claim liabilities.
Recently Issued Accounting Standards	Recently Issued Accounting Standards The Financial Accounting Standards Board (“FASB”) issued an accounting standards update (“ASU”) that changes certain disclosure requirements for fair value measurements. We adopted the ASU as of January 1, 2020 with no material effect on our Notes to Consolidated Financial Statements. The FASB issued an ASU that provides temporary optional expedients and exceptions to the guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from LIBOR and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (“SOFR”). Entities can elect not to apply certain modification accounting requirements to contracts affected by reference rate reform, if certain criteria are met. An entity that makes this election would not have to remeasure the contracts at the modification date or reassess a previous accounting determination. Entities can also elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met. The guidance in this ASU is optional and may be elected over the period March 12, 2020 through December 31, 2022 as reference rate reform activities occur. We will continue to evaluate the impact of this ASU; however, we currently expect to avail ourselves of such optional expedients and exceptions should our modified contracts meet the required criteria.
