Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES When used in these notes, references to the “Company”, “Green Brick”, “we”, “us” or “our” refer to the combined company, which has been renamed Green Brick Partners, Inc. and its subsidiaries, resulting from the acquisition by BioFuel Energy Corp. and its then consolidated subsidiaries (“BioFuel”) of JBGL Builder Finance LLC and its consolidated subsidiaries and affiliated companies (collectively, “Builder Finance”), and JBGL Capital Companies (“Capital”), a combined group of commonly managed limited liability companies and partnerships (collectively with Builder Finance, “JBGL”) by means of a reverse recapitalization transaction on October 27, 2014. Green Brick Partners, Inc. (formerly named BioFuel Energy Corp.) was incorporated as a Delaware corporation on April 11, 2006, to invest solely in BioFuel Energy, LLC, a limited liability company organized on January 25, 2006, to build and operate ethanol production facilities in the Midwestern United States. On November 22, 2013, the Company disposed of its ethanol plants and all related assets. Following the disposition of these production facilities, we were a public shell company with no substantial operations. On June 10, 2014, the Company entered into a definitive transaction agreement with the owners of JBGL, which provided that we would acquire JBGL for $275 million , payable in cash and shares of our common stock (the “Transaction”). JBGL is a real estate operator involved in the purchase and development of land for residential use, construction lending and home building operations. The Transaction was completed on October 27, 2014 (the “Transaction Date”). Pursuant to the terms of the Transaction, we paid the $275 million purchase price with approximately $191.8 million in cash and the remainder in 11,108,500 shares of our common stock valued at approximately $7.49 per share. The cash portion of the purchase price was primarily funded from the proceeds of a $70.0 million rights offering conducted by the Company (the $70.0 million includes proceeds from purchases of shares of common stock by certain funds and accounts managed by Greenlight Capital, Inc. and its affiliates (“Greenlight”) and Third Point LLC and its affiliates (“Third Point”)) and $150.0 million of debt financing provided by Greenlight pursuant to a loan agreement, with the lenders from time to time party thereto (the “Loan Agreement”), which provided for a five year term loan facility (the “Term Loan Facility”). In 2015, the Loan Agreement was repaid in full. The $70.0 million rights offering included a registered offering by the Company of transferable rights to the public holders of its common stock, as of September 15, 2014 (the “Rights Offering”) to purchase additional shares of common stock. Each right permitted the holder to purchase, at a rights price ultimately equal to $5.00 per share of common stock, 2.2445 shares of common stock. 4,843,384 shares of common stock were purchased in the public Rights Offering for aggregate gross proceeds of approximately $24.2 million . In addition to the Rights Offering, Greenlight and Third Point participated in a private rights offering to purchase additional shares of common stock pursuant to commitment letters. Pursuant to its commitment letter, Third Point agreed to participate in the private rights offering for its full basic subscription privilege in the Rights Offering and to purchase, simultaneously with the consummation of the Rights Offering to the public, all of the available shares not otherwise sold in the Rights Offering following the exercise of all other public holders’ basic subscription privileges. Pursuant to such commitment letters, Greenlight purchased 4,957,618 shares of common stock for aggregate gross proceeds of approximately $24.8 million and Third Point purchased 4,198,998 shares of common stock for aggregate gross proceeds of approximately $21.0 million . At the time the Transaction was completed, BioFuel was a non-operating public shell corporation with nominal operations and assets consisting of cash, deferred tax assets, and nominal other nonoperating assets. As a result of the Transaction, the owners and management of JBGL gained effective operating control of the combined company. As of the Transaction Date, BioFuel did not meet the definition of a business for accounting purposes. Accordingly, for financial reporting purposes, the Transaction was deemed to be a capital transaction in substance and recorded as a reverse recapitalization of JBGL whereby JBGL is deemed to be the continuing, surviving entity for accounting purposes, but through reorganization, has deemed to have adopted the capital structure of BioFuel. Because the acquisition was considered a reverse recapitalization for accounting purposes, the combined historical financial statements of JBGL became our historical financial statements and from the completion of the acquisition on October 27, 2014, the financial statements have been prepared on a consolidated basis. The assets and liabilities of BioFuel have been brought forward at their book value and no goodwill has been recognized in connection with the Transaction. As a result of the Transaction, Green Brick changed its business direction and is now in the real estate industry. We are a uniquely structured company that combines residential land development and homebuilding. We acquire and develop land, provide land and construction financing to our controlled builders and participate in the profits of our controlled builders. Our core markets are in the high growth U.S. metropolitan areas of Dallas, Texas and Atlanta, Georgia. We are engaged in all aspects of the homebuilding process, including land acquisition and development, entitlements, design, construction, marketing and sales and the creation of brand images at our residential neighborhoods and master planned communities. The condensed consolidated financial statements set forth in this Quarterly Report on Form 10-Q consist of JBGL and BioFuel Energy, LLC. Condensed Basis of Presentation and Principles of Consolidation The unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) as set forth in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) and applicable regulations of the Securities and Exchange Commission (“SEC”), but do not include all of the information and footnotes required for complete financial statements. In the opinion of management, the accompanying condensed consolidated financial statements for the periods presented reflect all adjustments, of a normal, recurring nature, necessary to fairly state our financial position, results of operations and cash flows. These condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2015 , included in our Annual Report on Form 10-K filed with the SEC on March 30, 2016 . Our operating results for the three and nine months ended September 30, 2016 are not necessarily indicative of the results that may be expected for any future periods. The condensed consolidated financial statements include the historic accounts of JBGL and are consolidated with Green Brick beginning October 27, 2014. All intercompany balances and transactions have been eliminated in consolidation. Investments in which the Company directly or indirectly has an interest of more than 50 percent and/or is able to exercise control over the operations have been fully consolidated and noncontrolling interests are stated separately in the condensed consolidated financial statements as required under the provisions of FASB ASC 810, Consolidations . Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes, including the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. Noncontrolling Interests We own 50% controlling interests in several builders. The financial statements of these builders are consolidated in our condensed consolidated financial statements. The noncontrolling interests attributable to the 50% minority interests not owned by us are included as part of noncontrolling interests on the condensed consolidated balance sheets. Segment Information The Company’s operations are organized into two reportable segments: builder operations and land development. Builder operations consist of two operating segments: Texas and Georgia. In accordance with ASC 280, Segment Reporting , in determining the most appropriate reportable segments, we considered similar economic and other characteristics, geography, including product types, production processes, average selling prices, gross profits, suppliers, land acquisition results, and underlying demand and supply. Reclassifications Beginning in the third quarter of 2015, model home furnishings were reclassified from property and equipment, net in the condensed consolidated balance sheet to inventory. Depreciation of model home furnishings for the three and nine months ended September 30, 2015 has been reclassified from depreciation and amortization expense in the accompanying condensed consolidated statements of income to cost of residential units to conform to the current period presentation. Cash related to refundable customer deposits, which are not held in escrow, has been reclassified from restricted cash in the accompanying condensed consolidated balance sheets as of December 31, 2015 and the accompanying condensed consolidated statements of cash flows for the nine months ended September 30, 2015 to cash and cash equivalents to conform to the current period presentation. Out-of-Period Adjustment During the fourth quarter ended December 31, 2015, the Company recorded an out-of-period adjustment associated with a $1.9 million overaccrual of distributions payable recorded during the fourth quarter ended December 31, 2014. As a result, as of December 31, 2014, accrued expenses was overstated and retained earnings was understated by $1.9 million . After evaluating the quantitative and qualitative aspects of the out-of-period adjustment, management has determined that the adjustment is not material to any prior period financial statements. Recent Accounting Pronouncements In May 2014, FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The standard will replace most existing revenue recognition guidance in GAAP when it becomes effective. In August 2015, FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date , which delayed the effective date of ASU No. 2014-09 by one year. Subsequent to the issuance of ASU 2014-09, the FASB issued several amendments in 2016 to the original standard including ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) , ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing and ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow Scope Improvements and Practical Expedients . These amendments do not change the core principle of the guidance stated in ASU 2014-09. Rather, they are intended to clarify and improve understanding of certain topics included in ASU 2014-09. ASU 2014-09 and the related amendments are effective for the Company beginning on January 1, 2018 . Early adoption is permitted for reporting periods beginning after December 15, 2016. The standard permits the use of either the full retrospective approach or the modified retrospective approach. The Company has not yet selected a transition method and is currently evaluating the effect that the standard will have on its condensed consolidated financial statements and related disclosures. In February 2015, FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis , which amends the consolidation requirements in ASC 810, primarily related to limited partnerships and VIEs. This standard was effective for the Company beginning on January 1, 2016 . The adoption of this standard did not have a material effect on the Company’s condensed consolidated financial statements and related disclosures. In April 2015, FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs , which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. This standard was effective for the Company beginning on January 1, 2016 . In August 2015, FASB issued ASU No. 2015-15, Interest — Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements — Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting , which clarified that the SEC staff would not object to an entity deferring and presenting debt issuance costs related to a line-of-credit arrangement as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of such arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. As permitted, the Company is deferring and presenting debt issuance costs related to its lines of credit as assets and subsequently amortizing the costs straight line over the term of the lines of credit. In November 2015, FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes , as part of its simplification initiative. The standard amends the existing guidance to require that deferred income tax liabilities and assets be classified as noncurrent in a classified balance sheet, and eliminates the prior guidance which required an entity to separate deferred tax liabilities and assets into a current amount and a noncurrent amount in a classified balance sheet. The standard is effective for the Company beginning on January 1, 2017 . Early adoption is permitted as of the beginning of an interim or annual period. Additionally, the new guidance may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The Company does not believe that the adoption of this standard will have a material effect on its condensed consolidated financial statements and related disclosures. In February 2016, FASB issued ASU No. 2016-02, Leases , which requires an entity that leases assets to classify the leases as either finance or operating leases and to record assets and liabilities for the rights and obligations created by long-term leases, regardless of the lease classification. The lease classification will determine whether the lease expense is recognized based on an effective interest rate method or on a straight line basis over the term of the lease. This standard is effective for the Company beginning on January 1, 2019 and must be adopted using a modified retrospective approach. The Company does not believe that the adoption of this standard will have a material effect on its condensed consolidated financial statements and related disclosures. In March 2016, FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , which simplifies several aspects related to the accounting for share-based payment transactions, including the accounting for income taxes, statutory tax withholding requirements and classification on the statement of cash flows. This standard is effective for the Company beginning on January 1, 2017 . The Company is currently evaluating the effect that this standard will have on its condensed consolidated financial statements and related disclosures. In August 2016, FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments , which reduces the existing diversity in practice in financial reporting across all industries by clarifying certain existing principles in ASC 230, Statement of Cash Flows , including providing additional guidance on how and what an entity should consider in determining the classification of certain cash receipts and cash payments. This standard is effective for the Company beginning on January 1, 2018 . The Company does not believe that the adoption of this standard will have a material effect on its condensed consolidated financial statements and related disclosures.

Earnings Per Share [Abstract]
Net Income Attributable to Green Brick Partners, Inc. Per Share	NET INCOME ATTRIBUTABLE TO GREEN BRICK PARTNERS, INC. PER SHARE The Company's restricted stock awards have the right to receive forfeitable dividends on an equal basis with common stock and therefore are not considered participating securities that must be included in the calculation of net income per share using the two-class method. Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during each period, adjusted for non-vested shares of restricted stock awards during each period. Diluted earnings per share is calculated using the treasury stock method and includes the effect of all dilutive securities, including stock options and restricted stock awards. The computation of basic and diluted net income attributable to Green Brick Partners, Inc. per share using the treasury stock method is as follows (in thousands, except per share amounts): Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Basic net income attributable to Green Brick Partners, Inc. per share Net income attributable to Green Brick Partners, Inc. —basic $ 6,243 $ 2,826 $ 16,080 $ 10,632 Weighted-average number of shares outstanding —basic 48,899 48,495 48,868 37,125 Basic net income attributable to Green Brick Partners, Inc. per share $ 0.13 $ 0.06 $ 0.33 $ 0.29 Diluted net income attributable to Green Brick Partners, Inc. per share Net income attributable to Green Brick Partners, Inc. —diluted $ 6,243 $ 2,826 $ 16,080 $ 10,632 Weighted-average number of shares used to compute basic net income attributable to Green Brick Partners, Inc. 48,899 48,495 48,868 37,125 Dilutive effect of stock options and restricted stock awards 8 100 3 36 Weighted-average number of shares outstanding —diluted 48,907 48,595 48,871 37,161 Diluted net income attributable to Green Brick Partners, Inc. per share $ 0.13 $ 0.06 $ 0.33 $ 0.29 The following securities that could potentially dilute earnings per share in the future are not included in the determination of diluted net income attributable to Green Brick Partners, Inc. per common share (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Antidilutive options to purchase common stock and restricted stock awards 113 — 186 67

Debt Disclosure [Abstract]
Debt	DEBT Lines of Credit Lines of credit outstanding as of September 30, 2016 and December 31, 2015 consist of the following (in thousands): September 30, 2016 December 31, 2015 Promissory note to Inwood National Bank (“Inwood”): Revolving credit facility (1) $ 21,500 $ 17,500 Unsecured revolving credit facility (2) 60,000 30,000 Total lines of credit $ 81,500 $ 47,500 (1) On July 30, 2015 , the Company replaced its John's Creek credit facility with a new revolving credit facility with Inwood, which provides for up to $50.0 million and is secured by land owned in John’s Creek, Georgia, Allen, Texas, and Carrollton, Texas. The costs associated with the new revolving credit facility of $0.4 million were deferred and are included in other assets in our condensed consolidated balance sheets. The Company is amortizing these debt issuance costs to interest expense over the term of the new revolving credit facility using the straight line method . Amounts outstanding under the new revolving credit facility is secured by mortgages on real property and security interests in certain personal property (to the extent that such personal property is connected with the use and enjoyment of the real property) that is owned by certain of the Company's subsidiaries, including land owned in John’s Creek, Georgia, Allen, Texas, and Carrollton, Texas. The amounts outstanding under the new revolving credit facility are also guaranteed by certain of the Company's subsidiaries. Before the amendment (as discussed below), the new revolving credit facility was subject to a borrowing base limitation equal to the sum of 50% of the total value of land and 60% of the total value of lots owned by certain of the Company's subsidiaries, each as determined by an independent appraiser, with the value of land being restricted from being more than 50% of the borrowing base. Outstanding borrowings under the new revolving credit facility bear interest payable monthly at a floating rate per annum equal to the rate announced by Bank of America, N.A., from time to time, as its “Prime Rate” (the “Index”) with such adjustments to the interest rate being made on the effective date of any change in the Index. Notwithstanding the foregoing, the interest may not, at any time, be less than 4% per annum or more than the lesser amount of 18% and the highest maximum rate allowed by applicable law. The entire unpaid principal balance and any accrued but unpaid interest is due and payable on the maturity date. As of September 30, 2016 , the interest rate on outstanding borrowings under the Credit Facility was 4.0% per annum. On May 3, 2016, the Company amended the new revolving credit facility. The amended revolving credit facility is subject to a borrowing base limitation equal to the sum of 50% of the total value of land and 65% of the total value of lots owned by certain of the Company's subsidiaries, each as determined by an independent appraiser, with the value of land being restricted from being more than 65% of the borrowing base. Beginning on August 1, 2017, a non-usage fee equal to 0.25% of the average unfunded amount of the $50.0 million commitment amount over a trailing 12 month period is due on or before August 1st of each year during the term of the amended revolving credit facility. The maturity date has been extended to May 1, 2019 . The costs associated with the amendment of $0.1 million were deferred and are included in other assets in our consolidated. Under the terms of the new revolving credit facility, the Company is required, among other things, to maintain minimum multiples of net worth in excess of the outstanding new revolving credit facility balance, minimum interest coverage and maximum leverage. The Company was in compliance with these financial covenants under the revolving credit facility as of September 30, 2016 . (2) On December 15, 2015, the Company entered into a credit agreement (the “Credit Agreement”) with the lenders named therein, and Citibank, N.A., as administrative agent, providing for a senior, unsecured revolving credit facility with aggregate lending commitments of up to $40.0 million (“Unsecured Revolving Credit Facility”). Before the Amendment (as defined and discussed below) increased the maximum amount of the Unsecured Revolving Credit Facility, the Company could, at its option and subject to certain terms and conditions, prior to the termination date, increase the amount of the revolving credit facility up to a maximum aggregate amount of $75.0 million . Commitments under the Unsecured Revolving Credit Facility are available until the period ending December 14, 2018, which period may be extended for additional one year periods, subject to the consent of the lenders and the satisfaction of certain other terms and conditions. Citibank, N.A. and Credit Suisse AG, Cayman Islands Branch have initially committed to provide $25.0 million and $15.0 million , respectively. The costs associated with the Unsecured Revolving Credit Facility of $0.5 million were deferred and are included in other assets in our condensed consolidated balance sheets. The Company is amortizing these debt issuance costs to interest expense over the term of the Unsecured Revolving Credit Facility using the straight line method . The Unsecured Revolving Credit Facility provides for interest rate options on advances at rates equal to either: (x) in the case of base rate advances, the highest of (i) Citibank’s base rate, (ii) the federal funds rate plus 0.5% , and (iii) the one-month LIBOR plus 1.0% , in each case plus 1.5% ; or (y) in the case of Eurodollar rate advances, the reserve adjusted LIBOR plus 2.5% . Interest on amounts borrowed under the Unsecured Revolving Credit Facility is payable in arrears quarterly on the last day of each March, June, September and December during such periods. As of September 30, 2016 , the interest rate on outstanding borrowings under the Credit Facility was 2.9% per annum. The Company pays the lenders a commitment fee on the amount of the unused commitments on a quarterly basis at a rate per annum equal to 0.45% . Outstanding borrowings under the Unsecured Revolving Credit Facility are subject to, among other things, a borrowing base. The borrowing base limitation is equal to the sum of: 100% of unrestricted cash (in excess of $15.0 million ); 85% of the book value of model homes, construction in progress homes, sold completed homes, and speculative homes (subject to certain limitations on the age and number of speculative homes and model homes); 65% of the book value of finished lots and land under development; and 50% of the book value of entitled land (subject to certain limitations on the value of entitled land and land under development as a percentage of the borrowing base). On August 31, 2016, the Company, entered into a First Amendment to the Credit Agreement (the “Amendment”), with Flagstar Bank, FSB (“Flagstar Bank”), the lenders named therein, and Citibank, N.A., as administrative agent, which amends the Credit Agreement. The Amendment adds Flagstar Bank as a lender under the Credit Agreement, with an initial commitment of $20.0 million , which increases the aggregate lending commitments available under the Unsecured Revolving Credit Facility from $40.0 million to $60.0 million . The Amendment also increases the maximum amount of the Unsecured Revolving Credit Facility to a maximum aggregate amount of $110.0 million , which further increases are available at the Company’s option, prior to the termination date, subject to certain terms and conditions. The costs associated with the Amendment of $0.2 million were deferred and are included in other assets in our condensed consolidated balance sheets. Additionally, under the terms of the Unsecured Revolving Credit Facility, the Company is required, among other things, to maintain compliance with various covenants, including financial covenants relating to a maximum Leverage Ratio, a minimum Interest Coverage Ratio, and a minimum Consolidated Tangible Net Worth, each as defined therein. The Company's compliance with these financial covenants is measured by calculations and metrics that are specifically defined or described by the terms of the Unsecured Revolving Credit Facility. The Company was in compliance with these covenants as of September 30, 2016 . Notes Payable Notes payable outstanding as of September 30, 2016 and December 31, 2015 consist of the following (in thousands): September 30, 2016 December 31, 2015 Note payable to unrelated third party: Briar Ridge Investments, LTD (1) $ 9,000 $ 9,000 Lyons Equities, Inc.

Notes were signed in relation to the subordination bearing interest between 8.0% and 14.0% , collateralized by liens on the homes built on each lot. The sellers released their lien upon payment of principle plus accrued interest at the closing of each individual home to a third party buyer. The subordinated lot notes were paid off during the three months ended March 31, 2016.

Equity [Abstract]
Share Repurchase Program	SHARE REPURCHASE PROGRAM In March 2016, the Company's Board of Directors authorized a share repurchase program of up to 1,000,000 shares of its common stock through 2017 . The timing, volume and nature of share repurchases will be at the discretion of management and dependent on market conditions, corporate and regulatory requirements and other factors, and may be suspended or discontinued at any time. The authorized repurchases will be made from time to time in the open market, through block trades or in privately negotiated transactions. No assurance can be given that any particular amount of common stock will be repurchased. All or part of the repurchases may be implemented under a Rule 10b5-1 trading plan, which would allow repurchases under pre-set terms at times when we might otherwise be prevented from doing so under insider trading laws or because of self-imposed blackout periods. This repurchase program may be modified, extended or terminated at the discretion of our Board of Directors at any time. We intend to finance the repurchases with available cash. No shares were repurchased during the nine months ended September 30, 2016 .

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	SHARE-BASED COMPENSATION We measure and account for share-based awards in accordance with ASC Topic 718, “ Compensation - Stock Compensation ”. Share-based compensation expense associated with stock options with vesting contingent upon the achievement of service conditions is recognized on a straight-line basis, net of estimated forfeitures of unvested stock options, over the requisite service period the awards are expected to vest. We estimate the aggregate intrinsic value of stock options with vesting contingent upon the achievement of service conditions as of the date the award was granted using the Black-Scholes option pricing model. The Black-Scholes option-pricing model requires the use of certain input variables, such as expected volatility, risk-free interest rate and expected award life. Share-Based Award Activity In April 2016, the Company granted 65,875 shares of common stock (the “Stock Bonus Awards”) to its Named Executive Officers, pursuant to the 2014 Equity Plan. At the time of the grant, the Stock Bonus Awards were 100% vested and non-forfeitable. The Stock Bonus Awards have a weighted grant-date fair value of $7.45 per share. The fair value of the Stock Bonus Awards were recorded as share-based compensation expense in April 2016. The Company's non-employee Board of Directors elected to defer up to 100% of their annual retainer fee, chairman fees and meeting fees in the form of common stock. In June 2016, the Company granted 37,886 restricted stock awards (“RSAs”) to certain non-employee Board of Directors, pursuant to the 2014 Equity Plan. The RSAs will become fully vested on the earlier of (i) the first anniversary of the date of grant of the shares of restricted common stock or (ii) the date of the Issuer's 2017 Annual Meeting of Stockholders. The RSAs have a weighted average grant-date fair value of $7.51 per share. The fair value of the outstanding shares of restricted stock awards will be recorded as share-based compensation expense over the vesting period. A summary of restricted stock awards activity during the nine months ended September 30, 2016 is as follows: Number of Shares (in thousands) Weighted Average Grant Date Fair Value per Share Nonvested, December 31, 2015 23 $ 8.73 Granted 104 $ 7.47 Vested (89 ) $ 7.78 Forfeited — $ — Nonvested, September 30, 2016 38 $ 7.51 A summary of stock option activity during the nine months ended September 30, 2016 is as follows: Number of Shares (in thousands) Weighted Average Exercise Price per Share Weighted Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) Options outstanding, December 31, 2015 500 $ 7.49 Granted — — Exercised — — Forfeited — — Options outstanding, September 30, 2016 500 $ 7.49 8.07 $ 385 Options exercisable, September 30, 2016 100 $ 7.49 8.07 $ 77 A summary of our unvested stock options during the nine months ended September 30, 2016 is as follows: Number of Shares (in thousands) Weighted Average Per Share Grant Date Fair Value Unvested, December 31, 2015 400 $ 2.88 Granted — $ — Vested — $ — Forfeited — $ — Unvested, September 30, 2016 400 $ 2.88 Valuation of Share-Based Awards We utilize the Black-Scholes option pricing model for estimating the grant date fair value of stock options. There were no stock options issued during the nine months ended September 30, 2016 and September 30, 2015 . Share-Based Compensation Expense Share-based compensation expense was $0.1 million and $1.0 million for the three and nine months ended September 30, 2016 , respectively, and $0.1 million and $0.3 million for the three and nine months ended September 30, 2015 , respectively. As of September 30, 2016 , the estimated total remaining unamortized share-based compensation expense related to unvested restricted stock awards and stock options, net of forfeitures, was $1.1 million which is expected to be recognized over a weighted-average period of 0.7 years. As of September 30, 2016 , the estimated total remaining unamortized share-based compensation expense related to stock options, net of forfeitures, was $0.9 million which is expected to be recognized over a weighted-average period of 3.1 years.

Related Party Transactions	RELATED PARTY TRANSACTIONS During the three and nine months ended September 30, 2016 and 2015 , the Company had related party transactions through the normal course of business. These transactions include the following: On October 27, 2014, in connection with the Transaction, the Company entered into the Loan Agreement, a guaranty and a pledge and security agreement with certain funds and accounts managed by Greenlight, our largest shareholder. Greenlight beneficially owns approximately 49.4% of the voting power of the Company. The Loan Agreement provided for a five year Term Loan Facility in an aggregate principal amount of $150.0 million which funded part of the Transaction. Certain subsidiaries of the Company guaranteed obligations under the Term Loan Facility pursuant to the guaranty. The Term Loan Facility bore interest at 9.0% per annum, payable quarterly, from October 27, 2014 through the first anniversary thereof and 10.0% per annum thereafter. On July 1, 2015 we used approximately $154.9 million of the net proceeds from the Equity Offering to repay all of the outstanding principal, interest and a prepayment premium under the Term Loan Facility. See Note 5 for further discussion of this repayment. In 2012, we formed Centre Living Homes, LLC (“Centre Living”), a builder that focuses on a limited number of homes and luxury townhomes each year in the Dallas, Texas market. Trevor Brickman, the son of Green Brick's Chief Executive Officer, is the President of Centre Living. Effective as of January 1, 2015, Centre Living's operating agreement was amended and restated to the same general terms as with our other builders, such that Green Brick's ownership interest in Centre Living is 50% and Trevor Brickman's ownership interest is 50% for future operations beginning January 1, 2015. Subsequent to this amendment, Green Brick has 51% voting control over the operations of Centre Living.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair Value of Financial Instruments The Company’s financial instruments, none of which are held for trading purposes, include cash and cash equivalents, restricted cash, accounts receivable, earnest money deposits, other assets, accounts payable, accrued liabilities, customer and builder deposits, obligations related to land not owned under option agreements, borrowings on lines of credit, and notes payable. The Company estimates that due to the short term nature of underlying instruments or the proximity of the underlying transaction to the applicable reporting date that the fair value of all financial instruments does not differ materially from the aggregate carrying values recorded in the condensed consolidated financial statements as of September 30, 2016 and December 31, 2015 . Per the fair value hierarchy, level 1 financial instruments include: cash and cash equivalents, restricted cash, earnest money deposits, and customer and builder deposits. All other instruments are deemed to be level 3. Fair Value of Nonfinancial Instruments Nonfinancial assets and liabilities include items such as inventory and long lived assets that are measured at cost unless the carrying value is determined to be not recoverable in which case the affected instrument is written down to fair value. During the nine months ended September 30, 2016 and the year ended December 31, 2015 , the Company did not record any fair value adjustments to those nonfinancial assets and liabilities measured at fair value on a nonrecurring basis.

Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Warranties The Company accrues an estimate of its exposure to warranty claims based on both current and historical home sales data and warranty costs incurred. The Company offers homeowners a comprehensive third party warranty on each home. Homes are generally covered by a ten year warranty for qualified and defined structural defects, one year for defects and products used, and two years for electrical, mechanical and plumbing systems. Warranty accruals are included within accrued expenses in the condensed consolidated balance sheets. Warranty activity, included in accrued expenses in our condensed consolidated balance sheets consists of the following (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Beginning balance $ 717 $ 504 $ 474 $ 460 Additions 341 169 859 545 Charges (205 ) (127 ) (480 ) (459 ) Ending balance $ 853 $ 546 $ 853 $ 546 Commitments The Company has leases associated with office space in Georgia and Texas which are classified as operating leases. Rent expense under these leases are included in the selling, general and administrative expense in the consolidated statements of income. Legal Matters Lawsuits, claims and proceedings may be instituted or asserted against us in the normal course of business. The Company is also subject to local, state and federal laws and regulations related to land development activities, house construction standards, sales practices, employment practices and environmental protection. As a result, the Company may be subject to periodic examinations or inquiry by agencies administering these laws and regulations. The Company records a reserve for potential legal claims and regulatory matters when they are probable of occurring and a potential loss is reasonably estimable. The Company accrues for these matters based on facts and circumstances specific to each matter and revises these estimates when necessary. In view of the inherent difficulty of predicting outcomes of legal claims and related contingencies, the Company generally cannot predict their ultimate resolution, related timing or eventual loss. If evaluations indicate loss contingencies that could be material are not probable, but are reasonably possible, the Company will disclose their nature with an estimate of possible range of losses or a statement that such loss is not reasonably estimable. We believe that the ultimate resolution of any claims and lawsuits will not have a material adverse effect on our results of operations and liquidity or on our financial position. As of September 30, 2016 and December 31, 2015 , the Company did not have any accruals for asserted or unasserted matters.

Investments in which the Company directly or indirectly has an interest of more than 50 percent and/or is able to exercise control over the operations have been fully consolidated and noncontrolling interests are stated separately in the condensed consolidated financial statements as required under the provisions of FASB ASC 810, Consolidations .
Use of Estimates	Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes, including the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.
Noncontrolling Interests	Noncontrolling Interests We own 50% controlling interests in several builders. The financial statements of these builders are consolidated in our condensed consolidated financial statements. The noncontrolling interests attributable to the 50% minority interests not owned by us are included as part of noncontrolling interests on the condensed consolidated balance sheets.
Segment Reporting	Segment Information The Company’s operations are organized into two reportable segments: builder operations and land development. Builder operations consist of two operating segments: Texas and Georgia. In accordance with ASC 280, Segment Reporting , in determining the most appropriate reportable segments, we considered similar economic and other characteristics, geography, including product types, production processes, average selling prices, gross profits, suppliers, land acquisition results, and underlying demand and supply.
Reclassifications	Reclassifications Beginning in the third quarter of 2015, model home furnishings were reclassified from property and equipment, net in the condensed consolidated balance sheet to inventory. Depreciation of model home furnishings for the three and nine months ended September 30, 2015 has been reclassified from depreciation and amortization expense in the accompanying condensed consolidated statements of income to cost of residential units to conform to the current period presentation. Cash related to refundable customer deposits, which are not held in escrow, has been reclassified from restricted cash in the accompanying condensed consolidated balance sheets as of December 31, 2015 and the accompanying condensed consolidated statements of cash flows for the nine months ended September 30, 2015 to cash and cash equivalents to conform to the current period presentation.
Out-of-Period Adjustment	Out-of-Period Adjustment During the fourth quarter ended December 31, 2015, the Company recorded an out-of-period adjustment associated with a $1.9 million overaccrual of distributions payable recorded during the fourth quarter ended December 31, 2014. As a result, as of December 31, 2014, accrued expenses was overstated and retained earnings was understated by $1.9 million . After evaluating the quantitative and qualitative aspects of the out-of-period adjustment, management has determined that the adjustment is not material to any prior period financial statements.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The standard will replace most existing revenue recognition guidance in GAAP when it becomes effective. In August 2015, FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date , which delayed the effective date of ASU No. 2014-09 by one year. Subsequent to the issuance of ASU 2014-09, the FASB issued several amendments in 2016 to the original standard including ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) , ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing and ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow Scope Improvements and Practical Expedients . These amendments do not change the core principle of the guidance stated in ASU 2014-09. Rather, they are intended to clarify and improve understanding of certain topics included in ASU 2014-09. ASU 2014-09 and the related amendments are effective for the Company beginning on January 1, 2018 . Early adoption is permitted for reporting periods beginning after December 15, 2016. The standard permits the use of either the full retrospective approach or the modified retrospective approach. The Company has not yet selected a transition method and is currently evaluating the effect that the standard will have on its condensed consolidated financial statements and related disclosures. In February 2015, FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis , which amends the consolidation requirements in ASC 810, primarily related to limited partnerships and VIEs. This standard was effective for the Company beginning on January 1, 2016 . The adoption of this standard did not have a material effect on the Company’s condensed consolidated financial statements and related disclosures. In April 2015, FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs , which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. This standard was effective for the Company beginning on January 1, 2016 . In August 2015, FASB issued ASU No. 2015-15, Interest — Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements — Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting , which clarified that the SEC staff would not object to an entity deferring and presenting debt issuance costs related to a line-of-credit arrangement as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of such arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. As permitted, the Company is deferring and presenting debt issuance costs related to its lines of credit as assets and subsequently amortizing the costs straight line over the term of the lines of credit. In November 2015, FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes , as part of its simplification initiative. The standard amends the existing guidance to require that deferred income tax liabilities and assets be classified as noncurrent in a classified balance sheet, and eliminates the prior guidance which required an entity to separate deferred tax liabilities and assets into a current amount and a noncurrent amount in a classified balance sheet. The standard is effective for the Company beginning on January 1, 2017 . Early adoption is permitted as of the beginning of an interim or annual period. Additionally, the new guidance may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The Company does not believe that the adoption of this standard will have a material effect on its condensed consolidated financial statements and related disclosures. In February 2016, FASB issued ASU No. 2016-02, Leases , which requires an entity that leases assets to classify the leases as either finance or operating leases and to record assets and liabilities for the rights and obligations created by long-term leases, regardless of the lease classification. The lease classification will determine whether the lease expense is recognized based on an effective interest rate method or on a straight line basis over the term of the lease. This standard is effective for the Company beginning on January 1, 2019 and must be adopted using a modified retrospective approach. The Company does not believe that the adoption of this standard will have a material effect on its condensed consolidated financial statements and related disclosures. In March 2016, FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , which simplifies several aspects related to the accounting for share-based payment transactions, including the accounting for income taxes, statutory tax withholding requirements and classification on the statement of cash flows. This standard is effective for the Company beginning on January 1, 2017 . The Company is currently evaluating the effect that this standard will have on its condensed consolidated financial statements and related disclosures. In August 2016, FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments , which reduces the existing diversity in practice in financial reporting across all industries by clarifying certain existing principles in ASC 230, Statement of Cash Flows , including providing additional guidance on how and what an entity should consider in determining the classification of certain cash receipts and cash payments. This standard is effective for the Company beginning on January 1, 2018 . The Company does not believe that the adoption of this standard will have a material effect on its condensed consolidated financial statements and related disclosures.

The costs associated with the new revolving credit facility of $0.4 million were deferred and are included in other assets in our condensed consolidated balance sheets. The Company is amortizing these debt issuance costs to interest expense over the term of the new revolving credit facility using the straight line method . Amounts outstanding under the new revolving credit facility is secured by mortgages on real property and security interests in certain personal property (to the extent that such personal property is connected with the use and enjoyment of the real property) that is owned by certain of the Company's subsidiaries, including land owned in John’s Creek, Georgia, Allen, Texas, and Carrollton, Texas.

Notwithstanding the foregoing, the interest may not, at any time, be less than 4% per annum or more than the lesser amount of 18% and the highest maximum rate allowed by applicable law. The entire unpaid principal balance and any accrued but unpaid interest is due and payable on the maturity date.

Under the terms of the new revolving credit facility, the Company is required, among other things, to maintain minimum multiples of net worth in excess of the outstanding new revolving credit facility balance, minimum interest coverage and maximum leverage.
