Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited Consolidated Financial Statements of Cavco Industries, Inc., and its subsidiaries (collectively, the "Company" or "Cavco"), have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") for Quarterly Reports on Form 10-Q and Article 10 of SEC Regulation S-X. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, these statements include all of the normal recurring adjustments necessary to fairly state the Company's Consolidated Financial Statements. Certain prior period amounts have been reclassified to conform to current period classification. The Company has evaluated subsequent events after the balance sheet date through the date of the filing of this report with the SEC; there were no disclosable subsequent events. These Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and the Notes to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended April 1, 2017, filed with the SEC on June 13, 2017. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and the accompanying Notes. Actual results could differ from those estimates. The Consolidated Statements of Comprehensive Income and Consolidated Statements of Cash Flows for the interim periods are not necessarily indicative of the results or cash flows for the full year. The Company operates on a 52-53 week fiscal year ending on the Saturday nearest to March 31 of each year. Each fiscal quarter consists of 13 weeks, with an occasional fourth quarter extending to 14 weeks, if necessary, for the fiscal year to end on the Saturday nearest to March 31. The Company's current fiscal year will end on March 31, 2018. The Company operates principally in two segments: (1) factory-built housing, which includes wholesale and retail systems-built housing operations, and (2) financial services, which includes manufactured housing consumer finance and insurance. The Company designs and builds a wide variety of affordable manufactured homes, modular homes and park model RVs in 20 factories located throughout the United States, which are sold to a network of independent retailers, through the Company's 41 Company-owned retail stores and to community owners and developers. Our financial services group is comprised of a mortgage subsidiary, CountryPlace Acceptance Corp. ("CountryPlace"), and an insurance subsidiary, Standard Casualty Co. ("Standard Casualty"). CountryPlace is an approved Federal National Mortgage Association ("FNMA" or "Fannie Mae") and Federal Home Loan Mortgage Corporation ("FHLMC" or "Freddie Mac") seller/servicer, and a Government National Mortgage Association ("GNMA" or "Ginnie Mae") mortgage-backed securities issuer which offers conforming mortgages, non-conforming mortgages and home-only loans to purchasers of factory-built homes. Standard Casualty provides property and casualty insurance to owners of manufactured homes. On April 3, 2017, the Company acquired Lexington Homes, Inc. ("Lexington"), which produces manufactured homes distributed in the Southeastern United States. This operation, with one manufactured housing production facility in Lexington, Mississippi, provides for further operating capacity, increased home production capabilities and further distribution into certain markets. The acquisition was accounted for as a business combination and the results of operations have been included since the date of acquisition. Our purchase price allocation is preliminary and subject to revision as more detailed analyses are completed and additional information about fair value of assets and liabilities becomes available, including additional information relating to tax matters and finalization of our valuation of identified intangible assets. Pro forma results of operations for the acquisition have not been presented because the effects of the business combination were not material to our consolidated results of operations. Recent Accounting Pronouncements. In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes ("ASU 2015-17"). ASU 2015-17 became effective in the current fiscal year. Therefore, we now present all deferred tax liabilities and assets as noncurrent on the balance sheet instead of separating these items into current and noncurrent amounts. The prior period was not retrospectively adjusted. In addition, in March 2016, the FASB issued ASU 2016-09, Compensation- Stock Compensation (Topic 718) ("ASU 2016-09"), which also became effective in the current fiscal year. As a result of this required implementation, excess tax benefits are recorded on exercises of stock options as a reduction of income tax expense in the consolidated statement of comprehensive income, whereas they were previously recognized in equity. In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The standard requires entities to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new guidance also includes a cohesive set of disclosure requirements intended to provide users of financial statements with comprehensive information about the nature, amount, timing and uncertainty of revenue and cash flows arising from a company's contracts with customers. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which deferred the effective date of the new revenue standard. Accordingly, the updated standard is effective for us beginning with the first quarter of the Company's fiscal year 2019. Our implementation approach has included performing a detailed study of the various types of agreements that we have with our customers and assessing conformity of our current accounting practices with the new standard. We are making progress in determining the impact of this guidance; however, we are still evaluating the full effects ASU 2014-09 will have on the Company's Consolidated Financial Statements and disclosures. We expect to adopt this guidance using the modified retrospective transition method. In January 2016, the FASB issued ASU 2016-01, Financial Instruments (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2016-01"). ASU 2016-01 will be effective beginning with the first quarter of the Company's fiscal year 2019. Upon adoption, we will be required to reclassify the gain (loss) related to our equity investment securities classified as available-for-sale from accumulated other comprehensive income ("AOCI") to retained earnings as a cumulative-effect adjustment and begin recording future changes in fair value through earnings. As of December 30, 2017, we had a gain of $2.3 million recorded in AOCI for our available-for-sale equity investments. The impact on the Company's Consolidated Financial Statements at adoption will depend on the net unrealized gains (losses) recorded in AOCI for these equity investments as of the date of adoption. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ("ASU 2016-02"). ASU 2016-02 will be effective beginning with the first quarter of the Company's fiscal year 2020, with early adoption permitted. The amendments require the recognition of leased assets and the related liabilities on the balance sheet for most leases, and recognition of expenses in the income statement in a manner similar to current accounting treatment. In addition, disclosures of key information about leasing arrangements will be required. Upon adoption, leases will be recognized and measured at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently evaluating the effect this ASU will have on the Company's Consolidated Financial Statements and disclosures. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"). ASU 2016-13 changes the impairment model for most financial assets and certain other instruments to base measurement on expected losses through a forward-looking model rather than a model based on incurred losses. The guidance also requires increased disclosures. ASU 2016-01 will be effective beginning with the first quarter of the Company's fiscal year 2021. The Company is currently evaluating the effect ASU 2016-13 will have on the Company's Consolidated Financial Statements and disclosures. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force ("ASU 2016-18"), which provides guidance on the presentation of restricted cash or restricted cash equivalents in the statement of cash flows. ASU 2016-18 will be effective beginning with the first quarter of the Company's fiscal year 2019. The adoption of ASU 2016-18 will only change the presentation of the Consolidated Statement of Cash Flows and is not expected to have a material impact on the consolidated financial statements. In March 2017, the FASB issued ASU 2017-08, Receivables — Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities ("ASU 2017-08"), which requires the premium on callable debt securities to be amortized to the earliest call date as opposed to the contractual life of the security. ASU 2017-08 will be effective beginning with the first quarter of the Company's fiscal year 2020. The Company is currently evaluating the effect ASU 2017-08 will have on the Company's Consolidated Financial Statements and disclosures. From time to time, new accounting pronouncements are issued by the FASB and other regulatory bodies that are adopted by the Company as of the specified effective dates. Unless otherwise discussed, management believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on the Company's Consolidated Financial Statements upon adoption. For a description of other significant accounting policies used by the Company in the preparation of its Consolidated Financial Statements, please refer to Note 1 of the Notes to Consolidated Financial Statements in the Form 10-K.
