April 4, 2001

Lennar Corporation
700 N.W. 107th Avenue
Miami, Florida 33172

Ladies and Gentlemen:

We have acted as counsel to Lennar Corporation (the "Company") in connection
with the offer and sale by the Company of $550,267,000 principal amount at
maturity of the Company's Zero Coupon Convertible Senior Subordinated Notes due
2021 and up to $82,540,000 principal amount at maturity of Notes to cover over
allotments, if any (the "Notes"). The Notes are being issued under the
Company's registration statement on Form S-3, file number 333-42586 (the
"Registration Statement") and are being offered by a Prospectus dated August
23, 2000 and a Prospectus Supplement dated March 30, 2001 (together, the "Final
Prospectus"). The Notes are the subject of an Indenture, dated as of December
31, 1997, between the Company and Bank One Trust Company, NA, as a successor
trustee, (the "Trustee"), as supplemented by a Fifth Supplemental Indenture
thereto (together, the "Indenture"). The Notes may be converted into up to
3,513,015 shares (the "Shares") of common stock, par value $.10 per share, of
the Company. In our capacity as counsel to the Company in this offering, we are
familiar with the proceedings, corporate and other, relating to the
authorization of the issuance of the Notes and the Shares issuable upon
conversion of the Notes.

Based on the foregoing, and such other examination of law and fact as we have
deemed necessary, we are of the opinion that:

     1.   The shares of Common Stock issuable upon conversion of the Notes have
          been duly reserved for issuance upon such conversion and, if and when
          issued upon such conversion, will be validly issued, fully paid and
          non-assessable and will conform to the description thereof contained
          in the Final Prospectus.

     2.   The Notes have each been duly and validly authorized, executed and
          delivered by the Company and, when paid for by the underwriter in
          accordance with the terms of the Underwriting Agreement, dated as of
          March 30, 2001, between the Company and Salomon Smith Barney, Inc.
          (assuming the due authorization, execution and delivery of the
          Indenture by the Trustee and due authentication and delivery of the
          Securities by the Trustee in accordance with the Indenture), will
          constitute the valid and legally binding obligations of the Company,
          entitled to the benefits of the Indenture, and enforceable against the
          Company in accordance with their terms, except that the enforcement
          thereof is subject to (i) bankruptcy, insolvency, reorganization,
          fraudulent conveyance, moratorium or other similar laws now or
          hereafter in effect relating to creditors' rights generally and (ii)
          general principles of equity and the discretion of the court before
          which any proceeding therefor may be brought (regardless of whether
          such enforcement is considered in a proceeding in equity or at law).

We consent to the filing of this opinion as an exhibit to the Form 8-K with
which it is being filed and to the reference to us under the caption "Legal
Matters" in the Final Prospectus which is a part of the Registration Statement.
