Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Such financial statements do not include all of the information and disclosures required by GAAP for complete financial statements. In our opinion, all adjustments (consisting primarily of normal recurring accruals) necessary for a fair presentation have been included in the accompanying financial statements. The results of our consolidated operations presented herein for the three and six months ended March 31, 2015 are not necessarily indicative of the results to be expected for the full year due to seasonal variations in operations and other items. For further information and a discussion of our significant accounting policies other than as discussed below, refer to Note 1 to our audited consolidated financial statements appearing in Beazer Homes’ Annual Report on Form 10-K for the fiscal year ended September 30, 2014 (the 2014 Annual Report). Over the past few years, we have discontinued homebuilding operations in certain of our markets. Results from our title services business and our exited markets are reported as discontinued operations in the accompanying unaudited consolidated statements of operations for all periods presented (see Note 16 for further discussion of our Discontinued Operations). We evaluated events that occurred after the balance sheet date but before the financial statements were issued for accounting treatment and disclosure. Basis of Consolidation. These unaudited consolidated financial statements present the consolidated financial position, income, comprehensive income and cash flows of the Company and our subsidiaries. Intercompany balances have been eliminated in consolidation. Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make informed estimates and judgments that affect the amounts reported in the unaudited consolidated financial statements and accompanying notes. Accordingly, actual results could differ from these estimates. Inventory Valuation. We assess our inventory assets no less than quarterly for recoverability in accordance with the policies as described in Notes 1 and 4 to the consolidated financial statements in our 2014 Annual Report. Our homebuilding inventories that are accounted for as held for development include land and home construction assets grouped together as communities. Homebuilding inventories held for development are stated at cost (including direct construction costs, capitalized indirect costs, capitalized interest and real estate taxes) unless facts and circumstances indicate that the carrying value of the assets may not be recoverable. For those communities for which construction and development activities are expected to occur in the future or have been idled (land held for future development), all applicable interest and real estate taxes are expensed as incurred and the inventory is stated at cost unless facts and circumstances indicate that the carrying value of the assets may not be recoverable. We record assets held for sale at the lower of the carrying value or fair value less costs to sell. Recent Accounting Pronouncements. Revenue from Contracts with Customers. In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). ASU 2014-09 requires companies to recognize revenue at an amount that the entity expects to be entitled to upon transferring control of goods or services to a customer, as opposed to when risks and rewards transfer to a customer under the existing revenue recognition guidance. The FASB has tentatively decided to defer for one year the effective date of ASU 2014-09, which would make the guidance effective for the Company's first fiscal year beginning after December 15, 2017. Additionally, the FASB also tentatively decided to permit entities to early adopt the standard, which allows for either full retrospective or modified retrospective methods of adoption, for reporting periods beginning after December 15, 2016. We are currently evaluating the impact of ASU 2014-09 on our consolidated financial statements. Presentation of Debt Issuance Costs. In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03"). ASU 2015-03 requires debt issuance costs to be presented on the balance sheet as a direct deduction from the related debt liability, similar to the presentation of debt discounts or premiums. The costs will continue to be amortized to interest expense using the effective interest method. ASU 2015-03 requires retrospective application to all prior periods presented in the financial statements. Upon transition, an entity is required to comply with the applicable disclosures for a change in accounting principle. The guidance within ASU 2015-03 will be effective for the Company's first fiscal year beginning after December 15, 2015, but we have the option of adopting the new requirements as of an earlier date. We are evaluating the impact of ASU 2015-03, but only expect our balance sheet presentation of debt issuance costs to change as a result. Refer to Note 9 for a discussion of our adoption of ASU 2013-11 pertaining to the presentation of an unrecognized tax benefit when a net operating loss carryforward, or similar tax loss, or a tax credit carryforward exists.

Basis of Presentation and Summary of Significant Accounting Policies

The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Such financial statements do not include all of the information and disclosures required by GAAP for complete financial statements. In our opinion, all adjustments (consisting primarily of normal recurring accruals) necessary for a fair presentation have been included in the accompanying financial statements. The results of our consolidated operations presented herein for the three and six months ended March 31, 2015 are not necessarily indicative of the results to be expected for the full year due to seasonal variations in operations and other items. For further information and a discussion of our significant accounting policies other than as discussed below, refer to Note 1 to our audited consolidated financial statements appearing in Beazer Homes’ Annual Report on Form 10-K for the fiscal year ended September 30, 2014 (the 2014 Annual Report).

Over the past few years, we have discontinued homebuilding operations in certain of our markets. Results from our title services business and our exited markets are reported as discontinued operations in the accompanying unaudited consolidated statements of operations for all periods presented (see Note 16 for further discussion of our Discontinued Operations). We evaluated events that occurred after the balance sheet date but before the financial statements were issued for accounting treatment and disclosure.

Basis of Consolidation. These unaudited consolidated financial statements present the consolidated financial position, income, comprehensive income and cash flows of the Company and our subsidiaries. Intercompany balances have been eliminated in consolidation.

Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make informed estimates and judgments that affect the amounts reported in the unaudited consolidated financial statements and accompanying notes. Accordingly, actual results could differ from these estimates.

Inventory Valuation. We assess our inventory assets no less than quarterly for recoverability in accordance with the policies as described in Notes 1 and 4 to the consolidated financial statements in our 2014 Annual Report. Our homebuilding inventories that are accounted for as held for development include land and home construction assets grouped together as communities. Homebuilding inventories held for development are stated at cost (including direct construction costs, capitalized indirect costs, capitalized interest and real estate taxes) unless facts and circumstances indicate that the carrying value of the assets may not be recoverable. For those communities for which construction and development activities are expected to occur in the future or have been idled (land held for future development), all applicable interest and real estate taxes are expensed as incurred and the inventory is stated at cost unless facts and circumstances indicate that the carrying value of the assets may not be recoverable. We record assets held for sale at the lower of the carrying value or fair value less costs to sell.

Recent Accounting Pronouncements.

Revenue from Contracts with Customers. In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). ASU 2014-09 requires companies to recognize revenue at an amount that the entity expects to be entitled to upon transferring control of goods or services to a customer, as opposed to when risks and rewards transfer to a customer under the existing revenue recognition guidance. The FASB has tentatively decided to defer for one year the effective date of ASU 2014-09, which would make the guidance effective for the Company's first fiscal year beginning after December 15, 2017. Additionally, the FASB also tentatively decided to permit entities to early adopt the standard, which allows for either full retrospective or modified retrospective methods of adoption, for reporting periods beginning after December 15, 2016. We are currently evaluating the impact of ASU 2014-09 on our consolidated financial statements.

Presentation of Debt Issuance Costs. In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03"). ASU 2015-03 requires debt issuance costs to be presented on the balance sheet as a direct deduction from the related debt liability, similar to the presentation of debt discounts or premiums.
