Re:     Pulte Homes, Inc. Registration Statement on Form S-4

Ladies and Gentlemen:

     We refer to the Registration Statement on Form S-4 (the “Registration Statement”) (File No. 333-158974) filed by Pulte Homes, Inc., a Michigan corporation (the “Company”), with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration by the Company of shares (the “Registered Shares”) of the Company’s common stock, par value $0.01 per share (“Common Stock”), and the associated Series A Junior Participating Preferred Share Purchase Rights of the Company (the “Registered Rights”). The Registered Shares and the Registered Rights are to be issued pursuant to the terms of the Agreement and Plan of Merger, dated as of April 7, 2009 (the “Merger Agreement”), by and among the Company, Pi Nevada Building Company, a Nevada corporation and wholly owned subsidiary of the Company (“Merger Sub”), and Centex Corporation, a Nevada corporation (“Centex”), which provides, among other things, that Merger Sub will merge with and into Centex, with Centex surviving the merger and becoming a wholly owned subsidiary of the Company (the “Merger”). The Registered Shares consist of (i) shares of Common Stock issuable at the effective time of the Merger (the “Closing Shares”) pursuant to (A) Section 2.1(a) of the Merger Agreement, relating to shares of Centex outstanding at the effective time of the Merger, and (B) Sections 5.6(a)(ii) and 5.6(a)(iii) of the Merger Agreement, relating to restricted stock and stock units and performance units of Centex outstanding at the effective time of the Merger, and (ii) shares of Common Stock issuable upon exercise of options (the “Substitute Options”) resulting from the conversion of Centex stock options outstanding at the effective time of the Merger pursuant to Section 5.6(a)(i) of the Merger Agreement (the “Option Shares”). The terms of the Registered Rights are set forth in the Section 382 Rights Agreement, dated March 5, 2009 (the “Rights Agreement”), between the Company and Computershare Trust Company, N.A., as rights agent, as amended. The Merger is subject to satisfaction or waiver of a number of conditions, including approval by the shareholders of the Company of an amendment to the Company’s Restated Articles of Incorporation increasing the total number of shares of authorized Common Stock (the “Charter Amendment”).

     We are familiar with and have examined the Registration Statement, the Merger Agreement, the Rights Agreement, the Company’s Restated Articles of Incorporation and the

We have also examined originals, or copies of originals certified to our satisfaction, of such agreements, documents, certificates and statements of the Company and other corporate documents and instruments, and have examined such questions of law and have satisfied ourselves as to such matters of fact, as we have considered relevant and necessary as a basis for this letter.

     2. Each Option Share will be validly issued, fully paid and nonassessable when (i) the Registration Statement, as finally amended, shall have become effective under the Securities Act, (ii) the issuance of the Registered Shares and the Charter Amendment shall have been approved by the shareholders of the Company, (iii) the certificate of amendment to the Company’s Restated Articles of Incorporation reflecting the Charter Amendment shall have been duly filed in accordance with the MBCA, (iv) the Merger shall have become effective under the NRS and (v) a certificate representing such Option Share shall have been duly executed, countersigned, registered and delivered to the person entitled thereto or, if the Option Share is uncertificated, valid book entry notations will have been made in the share register of the Company, in each case in accordance with the terms of the related Substitute Option and any applicable agreement or plan.

     3. The Registered Right associated with each Registered Share will be validly issued, fully paid and nonassessable when (i) the Registration Statement, as finally amended, shall have become effective under the Securities Act, (ii) such associated Registered Share shall have been duly issued as set forth in paragraph 1 or 2, as the case may be, and (iii)
