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, 2015 , we owned or had an interest in 32.5 million rentable square feet of in-service properties, 1.4 million rentable square feet of properties under development and approximately 500 acres of development land. The Company is the sole general partner of the Operating Partnership. At September 30, 2015 , the Company owned all of the Preferred Units and 94.9 million , or 97.0% , of the Common Units in the Operating Partnership. Limited partners own the remaining 2.9 million Common Units. During the nine months ended September 30, 2015 , the Company redeemed 26,820 Common Units for a like number of shares of Common Stock. Common Stock Offerings During the three and nine months ended September 30, 2015 , the Company issued 1,206,200 and 2,178,859 shares, respectively, of Common Stock under its equity sales agreements at an average gross sales price of $41.89 and $43.33 per share, respectively, and received net proceeds, after sales commissions, of $49.8 million and $93.0 million , respectively. As a result of this activity and the redemptions discussed above, the percentage of Common Units owned by the Company increased from 96.9% at December 31, 2014 to 97.0% at September 30, 2015 . 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. All intercompany transactions and accounts have been eliminated. At December 31, 2014 , we had involvement with, but were not the primary beneficiary in, an entity that we concluded to be a variable interest entity (see Note 3). During the second quarter of 2015, as a result of our partner’s irrevocable exercise of a buy-sell provision in our SF-HIW Harborview Plaza, LP ("Harborview") joint venture agreement, our partner’s right to put its 80.0% equity interest back to us became no longer exercisable. As a result, we recorded the original contribution transaction as a partial sale and recognized $2.2 million of gain. Our investment in this joint venture then qualified for the equity method of accounting, which resulted in the retrospective revision of the Consolidated Balance Sheets and Consolidated Statements of Equity and Capital for all prior periods presented. The effects of the retrospective application of the equity method of accounting to the Consolidated Statements of Income, Comprehensive Income and Cash Flows were not material. The effects of the retrospective application of the equity method of accounting to the Company's December 31, 2014 Balance Sheet were as follows: December 31, Previously Reported As Revised Net real estate assets $ 3,481,406 $ 3,452,006 Investments in and advances to unconsolidated affiliates $ 27,071 $ 50,685 Total Assets $ 4,004,909 $ 3,999,123 Financing obligations $ 23,519 $ 8,962 Distributions in excess of net income available for common stockholders $ (966,141 ) $ (957,370 ) Total Liabilities, Noncontrolling Interests in the Operating Partnership and Equity $ 4,004,909 $ 3,999,123 1. Description of Business and Significant Accounting Policies – Continued 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 2014 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 the Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates. Recently Issued Accounting Standards The Financial Accounting Standards Board ("FASB") recently issued an accounting standards update that requires the use of a new five-step model to recognize revenue from customer contracts. The five-step model requires that we identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when we satisfy the performance obligations. We will also be required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The accounting standards update is required to be adopted in 2018. Retrospective application is required either to all periods presented or with the cumulative effect of initial adoption recognized in the period of adoption. We are in the process of evaluating this accounting standards update. The FASB recently issued an accounting standards update that amends consolidation requirements. The amendments significantly change the consolidation analysis required under GAAP and will require companies to reevaluate all previous consolidation conclusions. The accounting standards update is required to be adopted in 2016. We are in the process of evaluating this accounting standards update. The FASB recently issued an accounting standards update that requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The accounting standards update is required to be adopted in 2016. Retrospective application is required. We are in the process of evaluating this accounting standards update.

Receivables [Abstract]
Mortgages and Notes Receivable	Mortgages and Notes Receivable Mortgages and notes receivable were $2.1 million and $13.1 million at September 30, 2015 and December 31, 2014 , respectively. During the second quarter of 2015, $9.9 million of secured acquisition financing provided to a third party in 2012 was repaid, including accrued interest. Previously, we concluded this arrangement to be an interest in a variable interest entity. However, since we did not have the power to direct matters that most significantly impact the activities of the entity, we did not qualify as the primary beneficiary. Accordingly, the entity was not consolidated. Our risk of loss with respect to this arrangement was limited to the carrying value of the mortgage receivable. We evaluate the ability to collect our mortgages and notes receivable by monitoring the leasing statistics and/or market fundamentals of these assets. As of September 30, 2015 , our mortgages and notes receivable were not in default and there were no other indicators of impairment.

Mortgages and Notes Payable - Continued Our $ 475.0 million unsecured revolving credit facility is scheduled to mature in January 2018 and includes an accordion feature that allows for an additional $ 75.0 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 110 basis points and the annual facility fee is 20 basis points. There was $ 265.0 million and $ 276.0 million outstanding under our revolving credit facility at September 30, 2015 and October 20, 2015 , respectively. At both September 30, 2015 and October 20, 2015 , we had $ 0.2 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 September 30, 2015 and October 20, 2015 was $ 209.8 million and $ 198.8 million , respectively. During the third quarter of 2015, we obtained a $350.0 million , six -month unsecured bridge facility. The bridge facility is originally scheduled to mature on March 28, 2016 . Assuming no defaults have occurred, we have an option to extend the maturity for an additional six -month period. The interest rate on the bridge facility at our current credit ratings is LIBOR plus 110 basis points . There was $250.0 million outstanding under our bridge facility at September 30, 2015 . The unused capacity of our bridge facility at September 30, 2015 was $100.0 million . During the second quarter of 2015, we amended our $225.0 million , seven-year unsecured bank term loan, which was scheduled to mature in January 2019 . We increased the borrowed amount to $350.0 million . The amended term loan is now scheduled to mature in June 2020 and the interest rate, based on our current credit ratings, was reduced from LIBOR plus 175 basis points to LIBOR plus 110 basis points. The interest rate is based on the higher of the publicly announced ratings from Moody’s Investors Service or Standard & Poor’s Ratings Services. The financial and other covenants under the amended term loan are unchanged. We incurred $1.3 million of deferred financing fees in connection with this amendment, which will be amortized along with existing unamortized deferred loan fees over the remaining term of the new loan. During the second quarter of 2015, we prepaid without penalty the remaining $39.4 million balance on a secured mortgage loan with an effective interest rate of 6.43% that was originally scheduled to mature in November 2015 . We recorded $0.2 million of loss on debt extinguishment related to this prepayment. During the second quarter of 2015, we acquired our joint venture partner’s 77.2% interest in a building in Orlando, FL. Simultaneously with this acquisition, the joint venture's previously existing mortgage note was restructured into a new $18.0 million first mortgage note and a $10.2 million subordinated note, both of which are scheduled to mature in July 2017 . The first mortgage note is interest only with an effective interest rate of 5.36% , payable monthly. The subordinated note has an effective interest rate of 8.6% . Additionally, we deposited $3.0 million into escrow to fund tenant improvements, leasing commissions and building improvements. The first mortgage note and subordinated note can be prepaid at any time commencing October 2016 upon a sale or refinancing of the property. In such event, the subordinated note and any and all accrued interest thereon would be deemed fully satisfied upon payment of a "waterfall payment," if any. Such "waterfall payment" would be a cash payment equal to 50.0% of the amount, if any, by which the net sale proceeds or appraised value in the event of a refinancing exceeds (1) the outstanding principal of the first mortgage note, (2) the funds deposited by us into escrow to fund tenant improvements, leasing commissions and building improvements and (3) a 10.0% return on such funds deposited by us into escrow. The fair value of the first mortgage note was $18.3 million and the fair value of the subordinated note equaled the projected waterfall payment of $1.0 million . We are currently in compliance with financial covenants and other requirements with respect to our consolidated debt.

Fair Value Disclosures [Abstract]
Disclosure About Fair Value of Financial Instruments	Disclosure About Fair Value of Financial Instruments The following summarizes the three 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 asset is the fair value of certain 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 LIBOR interest rates (forward curves) derived from observed market LIBOR interest rate curves. In addition, credit valuation adjustments are incorporated 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 (1) certain of our mortgages and notes receivable, which were estimated by the income approach utilizing internal cash flow projections and market interest rates to estimate the price that would be paid in an orderly transaction between market participants, and (2) our tax increment financing bond, which is not routinely traded but whose fair value is determined by the income approach utilizing contractual cash flows and market-based interest rates to estimate the projected redemption value based on quoted bid/ask prices for similar unrated municipal bonds. Our Level 3 liability is the fair value of our financing obligation, which was estimated by the income approach to approximate the price that would be paid in an orderly transaction between market participants, utilizing: (1) contractual cash flows; (2) market-based interest rates; and (3) a number of other assumptions including demand for space, competition for customers, changes in market rental rates, costs of operation and expected ownership periods. 9.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting, Policy [Policy Text Block]	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. All intercompany transactions and accounts have been eliminated.
Use of Estimates, Policy [Policy Text Block]	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 the Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Standards The Financial Accounting Standards Board ("FASB") recently issued an accounting standards update that requires the use of a new five-step model to recognize revenue from customer contracts. The five-step model requires that we identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when we satisfy the performance obligations. We will also be required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The accounting standards update is required to be adopted in 2018. Retrospective application is required either to all periods presented or with the cumulative effect of initial adoption recognized in the period of adoption. We are in the process of evaluating this accounting standards update. The FASB recently issued an accounting standards update that amends consolidation requirements. The amendments significantly change the consolidation analysis required under GAAP and will require companies to reevaluate all previous consolidation conclusions. The accounting standards update is required to be adopted in 2016. We are in the process of evaluating this accounting standards update. The FASB recently issued an accounting standards update that requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The accounting standards update is required to be adopted in 2016. Retrospective application is required. We are in the process of evaluating this accounting standards update.
