Greenwich, Conn., Town Code ch. 2, art. 18 § 2-140

(a) If the Commission determines after a hearing, based upon the affirmative vote of at least four (4) regular members and/or seated alternates, that the rental charge or proposed increase in the rental charge for any housing accommodation is so excessive, based on the standards and criteria set forth in § 2-138 subsections (a) and (b) of this chapter, as to be harsh and unconscionable, it may order that the rent be limited to such an amount as it determines to be fair and equitable, effective the month in which the tenant filed the complaint. The Commission's orders may include a reduction in a rental charge or proposed rent increase; a delay in an increased rental; or a phase-in of an increase in a rental charge not to exceed a fair and equitable rent, payable in installments over a period of time. Such delay or phase-in shall not reduce the total fair and equitable rent to which the landlord is entitled. Commission orders shall be effective for a maximum of one (1) year from the date of issuance. The Commission may also make such orders to redress any retaliatory action taken by the landlord against the tenant pursuant to C.G.S. § 7-148d and § 47a-20 including cease and desist orders. Nothing herein shall:
(1) Authorize the Commission to order a landlord to extend a lease beyond the proposed lease term; or
(2) Preclude a landlord from seeking a modification of the Commission's order(s) sooner based on a substantial change of circumstances.
(b) If the Commission determines after a hearing, based upon the affirmative vote of at least four (4) regular members and/or seated alternates, that a housing accommodation fails to comply with any ordinance of the Town of Greenwich, or state statute or regulation, relating to health and safety, the Commission may order the suspension of further payment of rent by the tenant, or an abatement in rent, until such time as the landlord makes the necessary changes, repairs or installations so as to bring such housing accommodation into compliance with such ordinance, statute, or regulation. If the Commission's order constitutes a suspension or abatement of rent until compliance, the full amount of rent or such lesser amount the Commission determines is appropriate during such period of non-compliance shall be paid to a designated third party to be held in escrow. Upon the landlord's full compliance with such ordinance, statute or regulation for which payments were made into such escrow, the Commission shall determine after hearing such distribution of the escrowed funds as it deems appropriate.
(c) If the Commission determines after a hearing that the rental charge or proposed increase in the rental charge for any housing accommodation is not so excessive, based on the standards and criteria set forth in § 2-138 subsections (a) and (b) of this chapter, as to be harsh and unconscionable, it shall order that the rental charge increase be paid by tenant to landlord retroactively effective the month in which the tenant filed the complaint.
