Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Consolidation	Basis of ConsolidationThe accompanying condensed consolidated financial statements include the accounts of Lennar Corporation and all subsidiaries, partnerships and other entities in which Lennar Corporation has a controlling interest and VIEs (see Note 16 of the Notes to the Condensed Consolidated Financial Statements) in which Lennar Corporation is deemed to be the primary beneficiary (the "Company"). The Company’s investments in both unconsolidated entities in which a significant, but less than controlling, interest is held and in VIEs in which the Company is not deemed to be the primary beneficiary, are accounted for by the equity method. All intercompany transactions and balances have been eliminated in consolidation.
Basis of Accounting	The condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended November 30, 2018. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for the fair presentation of the accompanying condensed consolidated financial statements have been made.The Company has historically experienced, and expects to continue to experience, variability in quarterly results. The condensed consolidated statements of operations for the three months ended February 28, 2019 are not necessarily indicative of the results to be expected for the full year.
Use of Estimates	Use of EstimatesThe preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
Reclassifications/Revisions	ReclassificationsCertain prior year amounts in the condensed consolidated financial statements have been reclassified to conform with the 2019 presentation. The Company's segments were adjusted to reflect Rialto Mortgage Finance ("RMF") and certain other Rialto assets within the Financial Services segment effective December 1, 2018. The remaining assets retained related to the Company's former Rialto segment were included in the Lennar Other segment. In addition, the Company's strategic technology investments, which were part of Homebuilding, were reclassified to be included in the Lennar Other segment. These reclassifications were between segments and had no impact on the Company's total assets, total equity, revenue or net income in the condensed consolidated financial statements.
