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 March 31, 2020, we owned or had an interest in 28.1 million rentable square feet of in-service properties, 1.2 million rentable square feet of office properties under development and approximately 250 acres of development land. The Company is the sole general partner of the Operating Partnership. At March 31, 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 three months ended March 31, 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 March 31, 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). In addition, during 2019, we acquired a building using a special purpose entity owned by a qualified intermediary to facilitate a potential Section 1031 reverse exchange under the Internal Revenue Code. To realize the tax deferral available under the Section 1031 exchange, we must complete the Section 1031 exchange, and take title to the to-be-exchanged building within 180 days of the acquisition date. We have determined that this entity is a variable interest entity of which we are the primary beneficiary and therefore, we consolidate this entity. As of March 31, 2020, this variable interest entity had total assets, liabilities and cash flows of $438.9 million, $21.7 million and $4.8 million, respectively. We completed the exchange by acquiring 100% of the special purpose entity on April 1, 2020. The assets of the special purpose entity can be used only to settle obligations of the special purpose entity and its creditors have no recourse to our wholly owned assets. 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 March 31, 2020, a reserve of $0.6 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 ASU can be applied from March 12, 2020 through December 31, 2022. We are in the process of evaluating 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 are in the process of evaluating the Lease Modification Q&A.

Leases	3 Months Ended
Leases	Mar. 31, 2020
Leases [Abstract]
Leases	Leases We generally lease our office properties to lessees in exchange for fixed monthly payments that cover rent, property taxes, insurance and certain cost recoveries, primarily common area maintenance. Office properties owned by us that are under lease are primarily located in Atlanta, Charlotte, Nashville, Orlando, Pittsburgh, Raleigh, Richmond and Tampa and are leased to a wide variety of lessees across many industries. Our leases are operating leases and mostly range from three to 10 years. We recognized rental and other revenues related to operating lease payments of $189.6 million during the three months ended March 31, 2020, of which variable lease payments were $16.5 million.

Variable Interest Entities [Abstract]

Consolidated Variable Interest Entity

We and The Bromley Companies formed a joint venture (the “Midtown One joint venture”) to construct Midtown One, a 150,000 square foot, multi-customer office building located in the mixed-use Midtown Tampa project in Tampa’s Westshore submarket. Midtown One has an anticipated total investment of $71.3 million. Construction of Midtown One 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 was fully funded as of March 31, 2020) 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 March 31, 2020, $2.2 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:



	March 31, 2020
Development in-process	$	29,073
Accounts payable, accrued expenses and other liabilities	$	1,669

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.

At March 31, 2020, our secured mortgage loan was collateralized by real estate assets with an undepreciated book value of $147.2 million.

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-month periods. The interest rate at our current credit ratings is LIBOR plus 100 basis points and the annual facility fee is 20 basis points. There was $87.0 million outstanding under our revolving credit facility at March 31, 2020. There were no amounts outstanding under our revolving credit facility at April 21, 2020. At both March 31, 2020 and April 21, 2020, we had $0.1 million of outstanding letters of credit, which reduces the availability on our revolving credit facility. As a result, the unused capacity of our revolving credit facility at March 31, 2020 and April 21, 2020 was $512.9 million and $599.9 million, respectively.

We are currently in compliance with financial covenants with respect to our consolidated debt.

We have considered our short-term liquidity needs and the adequacy of our estimated cash flows from operating activities and other available financing sources to meet these needs. We intend to 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.

Derivative Financial Instruments

The counterparties under our swaps are major financial institutions. 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. During the period from April 1, 2020 through March 31, 2021, we estimate that $0.4 million will be reclassified as a net increase to interest expense.

Disclosure About Fair Value of Financial Instruments

Mar. 31, 2020

Fair Value Disclosures [Abstract]

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:

Loss Contingency [Abstract]
Contingencies	15. Contingencies During the first quarter and subsequently, 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 and during the three months ended March 31, 2020, circumstances related to the COVID-19 pandemic may result in recording impairments, lease modifications and credit losses in future periods.

On April 16, 2020, we acquired development land in Raleigh for a purchase price, including capitalized acquisition costs, of $2.3 million. On April 28, 2020, the Company declared a cash dividend of $0.48 per share of Common Stock, which is payable on June 8, 2020 to stockholders of record as of May 18, 2020. See also Note 15 for information regarding the potential impact of the COVID-19 pandemic in future periods. The COVID-19 pandemic could materially and adversely impact or disrupt our financial condition, results of operations, cash flows and performance.

Description of Business and Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 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 March 31, 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). In addition, during 2019, we acquired a building using a special purpose entity owned by a qualified intermediary to facilitate a potential Section 1031 reverse exchange under the Internal Revenue Code. To realize the tax deferral available under the Section 1031 exchange, we must complete the Section 1031 exchange, and take title to the to-be-exchanged building within 180 days of the acquisition date. We have determined that this entity is a variable interest entity of which we are the primary beneficiary and therefore, we consolidate this entity. As of March 31, 2020, this variable interest entity had total assets, liabilities and cash flows of $438.9 million, $21.7 million and $4.8 million, respectively. We completed the exchange by acquiring 100% of the special purpose entity on April 1, 2020. The assets of the special purpose entity can be used only to settle obligations of the special purpose entity and its creditors have no recourse to our wholly owned assets. 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	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	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.
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 ASU can be applied from March 12, 2020 through December 31, 2022. We are in the process of evaluating 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 are in the process of evaluating the Lease Modification Q&A.
