Basis Of Presentation [Abstract]
Basis Of Consolidation	Basis of Consolidation The 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) 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. 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, 2014. 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, 2015 are not necessarily indicative of the results to be expected for the full year.
Revenue Recognition, Policy [Policy Text Block]	Rialto - Management Fee Revenue The Rialto segment provides services to a variety of legal entities and investment vehicles such as funds, joint ventures, co-invests, and other private equity structures to manage their respective investments. As a result, Rialto earns and receives management fees, underwriting fees and due diligence fees. These fees related to the Rialto segment are included in Rialto revenues and are recorded over the period in which the services are performed, fees are determinable and collectability is reasonably assured. Rialto receives investment management fees from investment vehicles based on 1) a percentage of committed capital during the commitment period and after the commitment period ends and 2) a percentage of invested capital less the portion of such invested capital utilized to acquire investments that have been sold (in whole or in part) or liquidated. Fees earned for underwriting and due diligence services are based on actual costs incurred. In certain situations, Rialto may earn additional fees when the return on assets managed exceeds contractually established thresholds. Such revenue is only booked when the contract terms are met, the contract is at, or near, completion and the amounts are known and collectability is reasonably assured. Since such revenue is recognized during the latter half of the life of the investment vehicle, after substantially all of the assets have been sold and investment gains and losses realized, the possibility of clawbacks is limited. In addition, Rialto may also receive tax distributions in order to cover income tax obligations resulting from allocations of taxable income due to Rialto's carried interests in the funds. These distributions are not subject to clawbacks and therefore are recorded as revenue when received.
Use Of Estimates	Use of Estimates The 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.

Disclosure of accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example, common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. The accounting policy may also address the accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.

- Definition

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
