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

Ladies and Gentlemen:

We have acted as counsel to TRI Pointe Homes, Inc., a Delaware corporation (the “Company”), and certain of its subsidiaries and affiliates listed on Annex A hereto (the “Guarantors”) in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of a Registration Statement on Form S-4 (the “Registration Statement”), under the Securities Act of 1933, as amended (the “Securities Act”), and the prospectus included therein in connection with the offering by the Company of (i) up to $450,000,000 aggregate principal amount of the Company’s 4.375% Senior Notes due 2019 (the “New 2019 Notes”), and the related guarantees, in exchange for a like principal amount of the Company’s outstanding 4.375% Senior Notes due 2019 (the “Outstanding 2019 Notes”), and the related guarantees; and (ii) up to $450,000,000 aggregate principal amount of the Company’s 5.875% Senior Notes due 2024 (the “New 2024 Notes” and, together with the New 2019 Notes, the “New Notes”), and the related guarantees, in exchange for a like principal amount of the Company’s outstanding 5.875% Senior Notes due 2019 (the “Outstanding 2024 Notes” and, together with the Outstanding 2019 Notes, the “Outstanding Notes”), and the related guarantees.

The New 2019 Notes are to be issued pursuant to the Indenture, dated as of June 13, 2014, among the Company, the Guarantors party thereto and U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture, dated as of July 7, 2014, as further supplemented by the Second Supplemental Indenture, dated as of July 7, 2014 (as supplemented, the “2019 Indenture”), and will be guaranteed pursuant to the terms of the 2019 Indenture and the notation endorsed on the New 2019 Notes by the Guarantors (the “2019 Note Guarantees”). The New 2024 Notes are to be issued pursuant to the Indenture, dated as of June 13, 2014, among the Company, the Guarantors party thereto and the Trustee, as supplemented by the First Supplemental Indenture, dated as of July 7, 2014, as further supplemented by the Second Supplemental Indenture, dated as of July 7, 2014 (as supplemented, the “2024 Indenture” and, together with the 2019 Indenture, the “Indentures”), and will be guaranteed pursuant to the terms of the 2024 Indenture and the notation endorsed on the New 2024 Notes by the Guarantors (the “2024 Note Guarantees” and, together with the 2019 Note Guarantees, the “Guarantees”).

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, the Outstanding Notes and the Guarantees related thereto and the forms of the New Notes and the Guarantees related thereto, 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. 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, 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, when the New Notes and the Guarantees related thereto are executed and authenticated in accordance with the provisions of the Indentures and issued and delivered in exchange for the applicable series of Outstanding Notes and the Guarantees related thereto in the manner described in the Registration Statement, the New Notes will constitute legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms, and the Guarantees of the New Notes will constitute legal, valid and binding obligations of the Guarantors obligated thereon, enforceable against such Guarantors in accordance with their respective terms.

The opinion expressed above is subject to the following additional exceptions, qualifications, limitations and assumptions:

A. We render no opinion herein as to matters involving the laws of any jurisdiction other than the State of New York, the United States of America and, to the extent relevant for our opinion herein, the California Corporations Code and the Delaware General Corporation Law. We are not admitted to practice in the State of Delaware; however, we are generally familiar with the Delaware General Corporation Law as currently in effect and have made such inquiries as we consider necessary to render the opinion above. Without limitation, we do not express any opinion regarding any Delaware contract law. This opinion is limited to the effect of the current state of the laws of the State of New York, the United States of America and, to the limited extent set forth above, the laws of the State of California and the State of Delaware and the facts as they currently exist. We assume no obligation to revise or supplement this opinion in the event of future changes in such laws or the interpretations thereof or such facts.

E. We express no opinion regarding the effectiveness of (i) any waiver of stay, extension or usury laws or of unknown future rights; (ii) any waiver (whether or not stated as such) under the Indentures, the Guarantees or the certificates evidencing the global New Notes or Outstanding Notes (collectively, the “Specified Note Documents”) of, or any consent thereunder relating to, unknown future rights or the rights of any party thereto existing, or duties owing to it, as a matter of law; (iii) any waiver (whether or not stated as such) contained in the Specified Note Documents of rights of any party, or duties owing to it, that is broadly or vaguely stated or does not describe the right or duty purportedly waived with reasonable specificity; (iv) 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 due to the negligence or willful misconduct of the indemnified party; (v) any purported fraudulent transfer “savings” clause; (vi) any waiver of the right to jury trial or (vii) any provision to the effect that every right or remedy is cumulative and may be exercised in addition to any other right or remedy or that the election of some particular remedy does not preclude recourse to one or more others.
