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

Ladies and Gentlemen:

We have acted as counsel for Beazer Homes USA, Inc., a Delaware corporation (the “Company”), and the subsidiaries of the Company listed on Schedule I hereto (the “Guarantors”), in connection with the proposed registration on a Registration Statement on Form S-4 (the “Registration Statement”) under the Securities Act of 1933, as amended, of (i) $200,000,000 principal amount of 7.250% Senior Notes due 2023 (the “Notes”) of the Company, to be issued in exchange (the “Exchange Offer”) for the Company’s outstanding 7.250% Senior Notes due 2023 pursuant to an indenture, dated as of February 1, 2013 (the “Indenture”), among the Company, the Guarantors, and U.S. Bank National Association, as Trustee (the “Trustee”), and (ii) the guarantees (the “Guarantees”) of each of the Guarantors to be endorsed upon the Notes, pursuant to the Indenture.

In our capacity as such counsel, we have reviewed the Indenture and form of the Notes. We have also reviewed such matters of law and examined original, certified, conformed or photographic copies of such other documents, records, agreements and certificates as we have deemed necessary as a basis for the opinions hereinafter expressed. In such review, we have assumed the genuineness of signatures on all documents submitted to us as originals and the conformity to original documents of all copies submitted to us as certified, conformed or photographic copies. We have relied, as to the matters set forth therein, on certificates of public officials. As to certain matters of fact material to this opinion, we have relied, without independent verification, upon certificates of the Company and the Guarantors.

Based upon and subject to the foregoing, and subject to the assumptions, qualifications and limitations set forth herein, we are of the opinion that:

1. the Notes have been duly authorized by the Company and, when the Notes have been duly executed by the Company, authenticated by the Trustee, and issued and delivered in the Exchange Offer in accordance with the terms of the Indenture, such Notes will be legally issued by the Company and will constitute the valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to bankruptcy, insolvency, reorganization, preference, receivership, moratorium, fraudulent conveyance or similar laws relating to or affecting
