Accounting Policies [Abstract]
Basis of Consolidation	Basis of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of Beazer Homes USA, Inc. and its consolidated subsidiaries. Intercompany transactions and balances have been eliminated in consolidation. Our net income (loss) is equivalent to our comprehensive income (loss), so we have not presented a separate statement of comprehensive income (loss). In the past, we have discontinued homebuilding operations in various markets. Results from certain of these exited markets are reported as discontinued operations in the accompanying unaudited condensed consolidated statements of operations for all periods presented (see Note 16 for a further discussion of our discontinued operations). Our fiscal year 2020 began on October 1, 2019 and ends on September 30, 2020. Our fiscal year 2019 began on October 1, 2018 and ended on September 30, 2019.
Use of Estimates	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 condensed consolidated financial statements and accompanying notes. Accordingly, actual results could differ from these estimates.
Share Repurchase Program	Share Repurchase ProgramDuring the first quarter of fiscal 2019, the Company's Board of Directors approved a share repurchase program that authorizes the Company to repurchase up to $50.0 million of its outstanding common stock. As part of this program, the Company repurchased common stock during fiscal 2019 through open market transactions, 10b5-1 plans, and accelerated share repurchase (ASR) agreements. All shares have been retired upon repurchase during fiscal 2019.
Inventory Valuation	Inventory Valuation Inventory assets are assessed for recoverability no less than quarterly in accordance with the policies described in Notes 2 and 5 to the audited consolidated financial statements within our 2019 Annual Report. Homebuilding inventories that are accounted for as held for development (projects in progress) 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 communities that 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 land held for sale at the lower of the carrying value or fair value less costs to sell.
Revenue Recognition	Revenue Recognition We recognize revenue upon the transfer of promised goods to our customers in an amount that reflects the consideration to which we expect to be entitled by applying the following five-step process specified in Accounting Standards Codification Topic 606. •Identify the contract(s) with a customer •Identify the performance obligations •Determine the transaction price •Allocate the transaction price •Recognize revenue when the performance obligations are met Homebuilding revenue Homebuilding revenue is reported net of any discounts and incentives and is generally recognized when title to and possession of the home are transferred to the buyer at the closing date. The performance obligation to deliver the home is generally satisfied in less than one year from the original contract date. Home sale contract assets consist of cash from home closings held by title companies in escrow for our benefit, typically for less than five days, and are considered accounts receivable. Contract liabilities include customer deposits related to sold but undelivered homes and totaled $16.3 million and $11.5 million as of June 30, 2020 and September 30, 2019, respectively. Of the customer liabilities outstanding as of September 30, 2019, $0.6 million and $10.6 million were recognized in revenue during the three and nine months ended June 30, 2020, respectively, upon closing of the related homes. Land sales and other revenue Land sales revenue relates to land that does not fit within our homebuilding programs and strategic plans. Land sales typically require cash consideration on the closing date, which is generally when performance obligations are satisfied. In some periods, we also have other revenue related to broker fees as well as fees received for general contractor services that we perform on behalf of third parties. Revenue for broker and general contractor services are typically immaterial and are generally recognized as performance obligations are satisfied.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Leases. On October 1, 2019, we adopted Accounting Standards Update (ASU) No. 2016-02, Leases (ASU 2016-02) and related amendments, collectively codified in ASC 842, Leases (ASC 842). ASC 842 requires lessees to record most leases on their balance sheets by recognizing a right-of-use asset, representing the right to use the identified asset during the lease term, and a corresponding lease liability, representing the present value of the lease payments over the lease term. Lessor accounting will be largely similar to that under the previous accounting rules. ASC 842 also requires significantly enhanced disclosures around an entity's leases and the related accounting. As part of our adoption of ASC 842, we applied a modified retrospective approach, whereby prior year financial statements were not recast. As a result, our consolidated financial statements as of and for the year ending September 30, 2019 were not restated and continues to be reported under the previous lease standard (ASC 840) and is therefore not comparative. We also elected the package of transition practical expedients, which allowed us to not reassess (1) whether any expired or existing contracts are or contain leases, (2) the lease classification for any expired or existing leases, and (3) the initial direct costs for any existing leases. In addition, we elected the practical expedient that allows lessees to account for lease and non-lease components together as a single component for all leases. Upon adoption of ASC 842, we recorded net operating lease right-of-use (ROU) assets of $13.9 million and operating lease liabilities of $16.0 million. Existing prepaid rent and accrued rent were recorded as an offset to the gross operating lease ROU assets. The adoption of ASC 842 did not have any impact on our retained earnings. See Note 8 for additional discussion of our operating leases. Fair Value Measurements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework (ASU 2018-13). The updated guidance improves the disclosure requirements for fair value measurements. The updated guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted for any removed or modified disclosures. We are currently assessing the impact of adopting the updated provisions. Internal-Use Software. In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (ASU 2018-15). ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This new guidance will be effective for public companies for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. The Company early adopted this standard as of April 1, 2020 on a prospective basis. The adoption of this standard had no material impact on our consolidated financial statements and related disclosure. Reference Rate Reform. In March 2020, the FASB issued ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting (ASU 2020-04). ASU 2020-04 provides companies with optional guidance to ease the potential accounting burden associated with transitioning away from reference rates that are expected to be discontinued. This guidance is effective beginning on March 12, 2020, and we may elect to apply the amendments prospectively through December 31, 2022. The Company is currently evaluating the effect that the new guidance will have on its consolidated financial statements and related disclosures.
Fair Value Measurements	As of the dates presented, we had assets on our condensed consolidated balance sheets that were required to be measured at fair value on a recurring or non-recurring basis. We use a fair value hierarchy that requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value as follows: •Level 1 – Quoted prices in active markets for identical assets or liabilities; •Level 2 – Inputs other than quoted prices included in Level 1 that are observable either directly or indirectly through corroboration with market data; and •Level 3 – Unobservable inputs that reflect our own estimates about the assumptions market participants would use in pricing the asset or liability. Certain of our assets are required to be recorded at fair value on a recurring basis. The fair value of our deferred compensation plan assets is based on market-corroborated inputs (Level 2). Certain of our assets are required to be recorded at fair value on a non-recurring basis when events and circumstances indicate that the carrying value of these assets may not be recovered. We review our long-lived assets, including inventory, for recoverability when factors indicate an impairment may exist, but no less than quarterly. Fair value on assets deemed to be impaired is determined based upon the type of asset being evaluated. Fair value of our owned inventory assets, when required to be calculated, is further discussed within Notes 2 and 5. The fair value of our investments in unconsolidated entities is determined primarily using a discounted cash flow model to value the underlying net assets of the respective entities. Due to the substantial use of unobservable inputs in valuing the assets on a non-recurring basis, they are classified within Level 3.

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 condensed consolidated financial statements and accompanying notes. Accordingly, actual results could differ from these estimates.

Share Repurchase Program

Share Repurchase ProgramDuring the first quarter of fiscal 2019, the Company's Board of Directors approved a share repurchase program that authorizes the Company to repurchase up to $50.0 million of its outstanding common stock. As part of this program, the Company repurchased common stock during fiscal 2019 through open market transactions, 10b5-1 plans, and accelerated share repurchase (ASR) agreements.

We record land held for sale at the lower of the carrying value or fair value less costs to sell.

Revenue Recognition

We recognize revenue upon the transfer of promised goods to our customers in an amount that reflects the consideration to which we expect to be entitled by applying the following five-step process specified in Accounting Standards Codification Topic 606.

•Identify the contract(s) with a customer

•Identify the performance obligations

•Determine the transaction price

•Allocate the transaction price

•Recognize revenue when the performance obligations are met

Homebuilding revenue

Homebuilding revenue is reported net of any discounts and incentives and is generally recognized when title to and possession of the home are transferred to the buyer at the closing date. The performance obligation to deliver the home is generally satisfied in less than one year from the original contract date. Home sale contract assets consist of cash from home closings held by title companies in escrow for our benefit, typically for less than five days, and are considered accounts receivable. Contract liabilities include customer deposits related to sold but undelivered homes and totaled $16.3 million and $11.5 million as of June 30, 2020 and September 30, 2019, respectively. Of the customer liabilities outstanding as of September 30, 2019, $0.6

million and $10.6 million were recognized in revenue during the three and nine months ended June 30, 2020, respectively, upon closing of the related homes.

Land sales and other revenue

Land sales revenue relates to land that does not fit within our homebuilding programs and strategic plans. Land sales typically require cash consideration on the closing date, which is generally when performance obligations are satisfied. In some periods, we also have other revenue related to broker fees as well as fees received for general contractor services that we perform on behalf of third parties. Revenue for broker and general contractor services are typically immaterial and are generally recognized as performance obligations are satisfied.

See Note 8 for additional discussion of our operating leases.

Fair Value Measurements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework (ASU 2018-13). The updated guidance improves the disclosure requirements for fair value measurements. The updated guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted for any removed or modified disclosures. We are currently assessing the impact of adopting the updated provisions.

Internal-Use Software. In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (ASU 2018-15). ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This new guidance will be effective for public companies for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. The Company early adopted this standard as of April 1, 2020 on a prospective basis. The adoption of this standard had no material impact on our consolidated financial statements and related disclosure.

Reference Rate Reform. In March 2020, the FASB issued ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting (ASU 2020-04). ASU 2020-04 provides companies with optional guidance to ease the potential accounting burden associated with transitioning away from reference rates that are expected to be discontinued. This guidance is effective beginning on March 12, 2020, and we may elect to apply the amendments prospectively through December 31, 2022. The Company is currently evaluating the effect that the new guidance will have on its consolidated financial statements and related disclosures.

Fair Value Measurements

As of the dates presented, we had assets on our condensed consolidated balance sheets that were required to be measured at fair value on a recurring or non-recurring basis. We use a fair value hierarchy that requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value as follows:

•Level 1 – Quoted prices in active markets for identical assets or liabilities;

•Level 2 – Inputs other than quoted prices included in Level 1 that are observable either directly or indirectly through corroboration with market data; and

•Level 3 – Unobservable inputs that reflect our own estimates about the assumptions market participants would use in pricing the asset or liability.

Certain of our assets are required to be recorded at fair value on a recurring basis. The fair value of our deferred compensation plan assets is based on market-corroborated inputs (Level 2).

Certain of our assets are required to be recorded at fair value on a non-recurring basis when events and circumstances indicate that the carrying value of these assets may not be recovered. We review our long-lived assets, including inventory, for recoverability when factors indicate an impairment may exist, but no less than quarterly. Fair value on assets deemed to be impaired is determined based upon the type of asset being evaluated. Fair value of our owned inventory assets, when required to be calculated, is further discussed within Notes 2 and 5. The fair value of our investments in unconsolidated entities is determined primarily using a discounted cash flow model to value the underlying net assets of the respective entities. Due to the substantial use of unobservable inputs in valuing the assets on a non-recurring basis, they are classified within Level 3.
