Significant Accounting Policies

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying 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. The condensed consolidated balance sheet as of December 31, 2018 was derived from the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . In the opinion of management the accompanying unaudited 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 the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . Operating results for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2019 or subsequent periods. Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of Green Brick Partners, Inc., its controlled subsidiaries, and variable interest entities (“VIEs”) in which Green Brick Partners, Inc. or one of its controlled subsidiaries is deemed to be the primary beneficiary (together, the “Company”, “we”, or “Green Brick”). All intercompany balances and transactions have been eliminated in consolidation. The Company uses the equity method of accounting for its investments in unconsolidated entities over which it exercises significant influence but does not have a controlling interest. Under the equity method, the Company’s share of the unconsolidated entities’ earnings or losses, if any, is included in the condensed consolidated statements of income. Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP requires management of 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. Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation. Beginning in the first quarter of 2019, the Company reclassified its sales commission expenses from cost of residential units to selling, general and administrative expense in the consolidated statements of income in order to be more readily comparable with a majority of its peers. For a complete set of the Company’s significant accounting policies, refer to Note 1 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . Changes and additions to significant accounting policies during the three months ended March 31, 2019 are presented below. Revenue Recognition The Company pays sales commissions to employees and/or outside realtors related to individual home sales which are expensed as incurred at the time of closing. Commissions on the sale of land parcels are also expensed as incurred upon closing. Sales commissions on the sale of homes are included in selling, general and administrative expense in the consolidated statements of income. Fair Value Measurements Transfers between levels of the fair value hierarchy are deemed to have occurred on the date of the event or change in circumstances that caused the transfer. Recent Accounting Pronouncements In February 2016, the FASB issued Accounting Standard Update (“ASU”) 2016-02, Leases (Topic 842) (“Topic 842”), which requires lessees to recognize leases on the balance sheet and disclose key information about leasing arrangements. Topic 842 was subsequently amended by ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842 ; ASU 2018-10, Codification Improvements to Topic 842, Leases ; ASU 2018-11, Targeted Improvements; and ASU 2019-01, Codification Improvements . The new standard establishes a right-of-use model (“ROU”) that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases are classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the statement of income. The new standard was effective for the Company on January 1, 2019 . A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. We adopted the new standard on January 1, 2019 and used the effective date as our date of initial application. Consequently, prior period financial information has not been recast and the disclosures required under the new standard have not been provided for dates and periods before January 1, 2019 . The new standard provides a number of optional practical expedients in transition. We elected the “package of practical expedients”, which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. We did not elect the use-of-hindsight or the practical expedient pertaining to land easements, the latter not being applicable to us. The new standard also provides practical expedients for an entity’s ongoing accounting. We elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, we have not recognized ROU assets or lease liabilities, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition. We also elected the practical expedient to not separate lease and non-lease components for all of our leases. We believe the most significant effects of the adoption of this standard relate to (1) the recognition of new ROU assets and lease liabilities on our consolidated balance sheet for our office operating leases and (2) providing new disclosures about our leasing activities. There was no change in our leasing activities as a result of adoption. Upon adoption, as of January 1, 2019, we recognized operating lease liabilities of $4.2 million based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases, as well as corresponding ROU assets of $4.1 million , the $0.1 million difference attributable to elimination of the accrued and prepaid rent existing as of January 1, 2019. In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”), which removes Step 2 of the goodwill impairment test. A goodwill impairment will now be determined by the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2019, with early adoption permitted. The Company does not expect the adoption of ASU 2017-04 to have a material impact on the Company’s consolidated financial statements.

Business Combinations [Abstract]
Business Combination	BUSINESS COMBINATION On April 26, 2018 (the “Acquisition Date”), following a series of transactions, the Company acquired substantially all of the assets and assumed certain liabilities of GHO Homes Corporation and its affiliates (“GHO”) through a newly formed subsidiary, GRBK GHO Homes, LLC (“GRBK GHO”), in which the Company holds an 80% controlling interest. GRBK GHO operates primarily in the Vero Beach, Florida market and is engaged in land and lot development, as well as all aspects of the homebuilding process. The acquisition allowed the Company to expand its operations into a new geographic market. The Company consolidates the financial statements of GRBK GHO as the Company owns 80% of the outstanding voting shares of the builder. The noncontrolling interest attributable to the 20% minority interest owned by our Florida-based partner is included as redeemable noncontrolling interest in equity of consolidated subsidiary in the Company’s condensed consolidated financial statements. The following table shows the changes in redeemable noncontrolling interest in equity of consolidated subsidiary during the three months ended March 31, 2019 (in thousands): Balance at December 31, 2018 $ 8,531 Net income 644 Accretion of redeemable noncontrolling interest 1,120 Balance at March 31, 2019 $ 10,295 Under the terms of the purchase agreement, the Company may be obligated to pay contingent consideration to our partner if certain annual performance targets are met over the three-year period following the Acquisition Date. The performance targets specified in the purchase agreement were met for the period from April 26, 2018 through December 31, 2018 , and contingent consideration of $1.8 million was earned by the minority partner in 2018 and paid by the Company in April 2019. Estimates of the undiscounted contingent consideration payouts for the period from January 1, 2019 through April 26, 2021 range from $1.4 million to $3.7 million .

Earnings Per Share [Abstract]
Net Income Attributable to Green Brick Partners, Inc. Per Share	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 nonvested 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 is as follows (in thousands, except per share amounts): Three Months Ended March 31, 2019 2018 Net income attributable to Green Brick Partners, Inc. $ 12,605 $ 11,203 Weighted-average number of shares outstanding - basic 50,563 50,577 Basic net income attributable to Green Brick Partners, Inc. per share $ 0.25 $ 0.22 Weighted-average number of shares outstanding - basic 50,563 50,577 Dilutive effect of stock options and restricted stock awards 42 141 Weighted-average number of shares outstanding - diluted 50,605 50,718 Diluted net income attributable to Green Brick Partners, Inc. per share $ 0.25 $ 0.22 The following shares which 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 March 31, 2019 2018 Antidilutive options to purchase common stock and restricted stock awards 21 —

Transaction Price Allocated to the Remaining Performance Obligations The aggregate amount of transaction price allocated to the remaining performance obligations on our land sale and lot option contracts is $92.1 million . The Company will recognize the remaining revenue when the lots are taken down, or upon closing for the sale of a land parcel, which is expected to occur as follows (in thousands): Total Remainder of 2019 $ 42,724 2020 33,936 2021 15,476 Total $ 92,136 The timing of lot takedowns is contingent upon a number of factors, including customer needs, the number of lots being purchased, receipt of acceptance of the plat by the municipality, weather-related delays, and agreed-upon lot takedown schedules. Our contracts with homebuyers have a duration of less than one year. As such, the Company uses the practical expedient as allowed under ASC 606, Revenue from Contracts with Customers, and has not disclosed the transaction price allocated to remaining performance obligations as of the end of the reporting period.

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, restricted cash, receivables, earnest money deposits, other assets, accounts payable, accrued expenses, customer and builder deposits, borrowings on lines of credit, and notes payable. Per the fair value hierarchy, level 1 financial instruments include: cash, restricted cash, receivables, earnest money deposits, other assets, accounts payable, accrued expenses, and customer and builder deposits due to their short-term nature. The Company estimates that, due to the short-term nature of the underlying financial instruments or the proximity of the underlying transaction to the applicable reporting date, the fair value of level 1 financial instruments does not differ materially from the aggregate carrying values recorded in the consolidated financial statements as of March 31, 2019 and December 31, 2018 . Level 2 financial instruments include borrowings on lines of credit. Due to the short-term nature and floating interest rate terms, the carrying amounts of borrowings on lines of credit are deemed to approximate fair value. The fair value of the contingent consideration liability related to the GRBK GHO business combination was estimated using a Monte Carlo simulation model under the option pricing method. As the measurement of the contingent consideration is based primarily on significant inputs not observable in the market, it represents a level 3 measurement. Key inputs in measuring the fair value of the contingent consideration liability are management’s projections of GRBK GHO’s net income and debt, the discount rate that reflects the risk associated with achieving the milestones of the contingent consideration payments, and expected volatility of earnings. The discount rate used in the simulation was an estimated risk free rate which ranged from 2.0% to 2.6% over the term of the contingent consideration. The expected volatility as derived from comparable publicly traded companies was estimated at 45%. The reconciliation of the beginning and ending balances for level 3 measurements is as follows (in thousands): Carrying Value Estimated Fair Value Contingent consideration liability, balance as of December 31, 2018 $ 2,207 $ 2,207 Change in fair value of contingent consideration 454 454 Contingent consideration liability, balance as of March 31, 2019 $ 2,661 $ 2,661 There were no transfers between the levels of the fair value hierarchy for any of our financial instruments during the three months ended March 31, 2019 . Fair Value of Nonfinancial Instruments Nonfinancial assets and liabilities include inventory which is 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. Per the fair value hierarchy, these items are level 3 nonfinancial instruments. For additional information on the Company’s inventory, refer to Note 4.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Letters of Credit and Performance Bonds During the ordinary course of business, certain regulatory agencies and municipalities require the Company to post letters of credit or performance bonds related to development projects. As of March 31, 2019 and December 31, 2018 , letters of credit outstanding were $2.2 million and $2.2 million , respectively, and performance bonds outstanding totaled $5.4 million and $5.3 million , respectively. The Company does not believe that it is likely that any material claims will be made under a letter of credit or performance bond in the foreseeable future. Warranties Warranty accruals are included within accrued expenses on the condensed consolidated balance sheets. Warranty activity during the three months ended March 31, 2019 and 2018 consisted of the following (in thousands): Three Months Ended March 31, 2019 2018 Warranty accrual, beginning of period $ 2,980 $ 2,083 Warranties issued 653 404 Changes in liability for existing warranties (144 ) (4 ) Settlements (862 ) (247 ) Warranty accrual, end of period $ 2,627 $ 2,236 Operating Leases The Company has leases associated with office and design center space that, at the commencement date, have a lease term of more than 12 months and are classified as operating leases. The exercise of any extension options available in such operating lease contracts is not reasonably certain. Operating lease cost of $0.3 million for the three months ended March 31, 2019 is included in selling, general and administrative expense in the condensed consolidated statements of income. For the three months ended March 31, 2019 , cash paid for amounts included in the measurement of operating lease liabilities was $0.3 million . As of March 31, 2019 , the weighted-average remaining lease term and the weighted-average discount rate used in calculating our lease liabilities were 3.9 years and 5.25% , respectively. The future annual undiscounted cash flows in relation to the operating leases and a reconciliation of such undiscounted cash flows to the operating lease liabilities recognized in the condensed consolidated balance sheet as of March 31, 2019 are presented below (in thousands): Remainder of 2019 $ 896 2020 1,235 2021 1,011 2022 734 2023 558 Total future lease payments $ 4,434 Less: Interest 438 Present value of lease liabilities $ 3,996 The Company elected the short-term lease recognition exemption for all leases that, at the commencement date, have a lease term of 12 months or less and do not include an option to purchase the underlying asset that the Company is reasonably certain to exercise. For such leases, the Company does not recognize ROU assets or lease liabilities and instead recognizes lease payments in the condensed consolidated income statements on a straight-line basis. Short-term lease cost of $0.1 million for the three months ended March 31, 2019 related to such lease contracts is included in selling, general and administrative expense in the condensed consolidated statements of income. Land and Lot Option Contracts In the ordinary course of business, the Company enters into land and lot option contracts in order to procure land for the construction of homes in the future. Earnest money deposits act as security for such contracts. Certain of our earnest money deposits are subject to first priority liens on the land that we have contracted to procure. As of March 31, 2019 and December 31, 2018 , there were 2,308 and 1,843 lots under option, respectively, including option contracts for land intended to be developed into lots. The land and lot option contracts in place as of March 31, 2019 provide for potential land and lot purchase payments in each year through 2022. If each option contract in place as of March 31, 2019 was exercised, expected purchase payments would be as follows (in thousands): Total Remainder of 2019 $ 107,083 2020 72,595 2021 24,779 2022 1,970 Total $ 206,427 Deposits and pre-acquisition costs written off related to option contracts abandoned totaled $0.5 million and $0.1 million for the three months ended March 31, 2019 and 2018 , respectively. 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, title company regulations, 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 an accrual 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 the possible range of losses or a statement that such loss is not reasonably estimable. We believe that the disposition of legal claims and related contingencies will not have a material adverse effect on our results of operations and liquidity or on our financial condition.
