Conn. Gen. Stat. § 8-13q

(b) After a municipality has received from the commissioner a preliminary letter of eligibility, the zoning commission of the municipality may adopt the incentive housing zone regulations and design standards as proposed to the commissioner for preliminary approval. Not later than thirty days after receipt from the municipality of a written statement that its zoning commission has adopted the proposed regulations and standards, the commissioner shall issue a letter of final approval of the incentive housing zone. Nonissuance of a letter of final approval not more than thirty days after receipt of the written statement shall be deemed disapproval of the zone after which the municipality may reapply for determination of eligibility under this section.

(c) The commissioner shall not approve any proposed incentive housing zone for which the proposed regulations or design standards have the intent or effect of discriminating against, making unavailable, denying or impairing the physical or financial feasibility of housing which is receiving or will receive financial assistance under any governmental program for the construction or substantial rehabilitation of low or moderate income housing, or any housing occupied by persons receiving rental assistance under chapter 319uu or Section 1437f of Title 42 of the United States Code.

(d) Any amendment to the regulations or design standards approved by the commissioner for preliminary or final eligibility shall be submitted to the commissioner for approval as set forth in this section. The commissioner shall approve or disapprove such amendment not more than sixty days after receipt of the amendment. Nonissuance of the decision to approve or disapprove such amendment within such period, the amendment shall be deemed to be disapproved. Thereafter, the commission may reapply for approval of the amendment.

(e) Nothing in this section or in section 8-13s shall preclude a municipality that has filed an application for preliminary determination of eligibility for a zone adoption payment pursuant to section 8-13p from waiving its right to receive such payment. Any municipality that intends to waive such right shall provide to the commissioner a written notice of its intent with the statement that its zoning commission has adopted incentive housing zone regulations and design standards.
