Ladies and Gentlemen:

We have acted as special counsel to CalAtlantic Group, Inc., a Delaware corporation (the “Company”), and certain of its subsidiaries listed on Annex A hereto (the “Guarantors”) in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of the prospectus supplement dated March 30, 2017, filed with the Commission pursuant to Rule 424(b) of the Securities Act of 1933, as amended (the “Securities Act”) on March 31, 2017 (the “Prospectus Supplement”), and the offering by the Company pursuant thereto of $125,000,000 principal amount of the Company’s 5.875% Senior Notes due 2024 (the “2024 Notes”) and $100,000,000 principal amount of the Company’s 5.250% Senior Notes due 2026 (the “2026 Notes” and, together with the 2024 Notes, the “Notes”) and the guarantees of the Company’s payment obligations under the Notes by the Guarantors (the “Guarantees”).

The 2024 Notes and the related Guarantees have been issued pursuant to the Indenture dated as of April 1, 1999 (the “Base Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A. (as successor in interest to J.P. Morgan Trust Company, National Association, Bank One Trust Company, N.A. and The First National Bank of Chicago), as trustee (the “Trustee”), as supplemented by the Twenty-First Supplemental Indenture, dated as of November 6, 2014, among the Company, the Guarantors and the Trustee (the “Twenty-First Supplemental Indenture”), the Twenty-Fifth Supplemental Indenture, dated as October 1, 2015, among the Company, the Guarantors and the Trustee (the “Twenty-Fifth Supplemental Indenture”) and the officers’ certificate of the Company dated as of the date hereof (the “Notes Officers’ Certificate”) delivered with respect to the 2024 Notes pursuant to Section 3.02(h) of the Twenty-First Supplemental Indenture (the Notes Officers’ Certificate and, together with the Base Indenture, the Twenty-First Supplemental Indenture and the Twenty-Fifth Supplemental Indenture, the “2024 Indenture”). The 2026 Notes and the related Guarantees have been issued pursuant to the Base Indenture, as supplemented by the Twenty-Seventh Supplemental Indenture, dated as of May 31, 2016, among the Company, the Guarantors and the Trustee (the “Twenty-Seventh Supplemental Indenture”) and the Notes Officers’ Certificate delivered with respect to the 2026 Notes pursuant to Section 3.02(h) of the Twenty-Seventh Supplemental Indenture.

Base Indenture, the Twenty-Seventh Supplemental Indenture and the Notes Officers’ Certificate are referred to collectively as the “2026 Indenture” and the 2024 Indenture and the 2026 Indenture are referred to collectively as the “Indentures.”

In arriving at the opinions expressed below, we have examined originals, or copies certified or otherwise identified to our satisfaction as being true and complete copies of the originals, of the Indentures (including the Guarantees included therein), the Notes, the Registration Statement on Form S-3, file no. 333-207309, filed with the Commission under the Securities Act on October 6, 2015 (the “Registration Statement”), and such other documents, corporate records, certificates of officers of the Company and the Guarantors and of public officials and other instruments as we have deemed necessary or advisable to enable us to render these opinions. In our examination, we have assumed, without independent investigation, the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as copies. To the extent that our opinions may be dependent upon such matters, we have assumed, without independent investigation, that each of the Guarantors identified on Annex A as “Florida Guarantors” is validly existing under the laws of its jurisdiction of incorporation, has all requisite partnership power to execute, deliver and perform its obligations under the Indentures and the Notes to which it is a party; that the execution and delivery of such documents by each such Guarantor and the performance of its obligations thereunder have been duly authorized by all necessary partnership action and do not violate any law, regulation, order, judgment or decree applicable to each such Guarantor; and that such documents have been duly executed and delivered by each such party. As to any facts material to these opinions, we have relied to the extent we deemed appropriate and without independent investigation upon statements and representations of officers and other representatives of the Company and the Guarantors and others.

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

1.    The Notes are legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms.

2.    The Guarantees of the Notes are legal, valid and binding obligations of the Guarantors obligated thereon, enforceable against such Guarantors in accordance with their respective terms.

We are not admitted to practice in the State of Delaware; however, we are generally familiar with the Delaware General Corporation Law and the Delaware Limited Liability Company Act as currently in effect and have made such inquiries as we consider necessary to render the opinions above. We have further assumed without independent investigation that the operating agreement of each of the Guarantors that is a Delaware limited liability company constitutes a legal, valid and binding obligation of each party thereto, enforceable against it in accordance with its terms; to the extent our opinions in paragraph 2 above are dependent on the interpretation of such agreement, it is based on the plain meaning of the provisions thereof in light of the Delaware Limited Liability Company Act. Without limitation, we do not express any opinion regarding any Delaware contract law.

C.    We express no opinion regarding the effectiveness of (i) any waiver of stay, extension or usury laws or of unknown future rights, (ii) provisions relating to indemnification, exculpation or contribution, to the extent such provisions may be held unenforceable as contrary to public policy or federal or state securities laws, or (iii) any purported fraudulent transfer “savings” clause.
