Mansfield, Conn., Code of Ordinances ch. 18 (2026) § 18-6

A. No landlord shall engage in retaliatory actions. Retaliatory actions by a landlord include but are not limited to the following: (1) Engaging in any action prohibited by C.G.S. § 47a-20 or § 21-80a within six months after any event listed in such statutes, including but not limited to within six months after the tenant has filed a complaint with the Commission; (2) Refusing to renew the lease or other rental agreement of any tenant; bringing or maintaining an action or proceeding against the tenant to recover possession of the dwelling unit; demanding an increase in rent from the tenant; decreasing the services to which the tenant has previously been entitled; or verbally, physically or sexually harassing a tenant because a tenant has filed a complaint with the fair rent commission; (3) Engaging in any other action determined by the Commission, after a hearing, to constitute landlord retaliation as set forth in C.G.S. § 7-148d(b). B. In the initial notice scheduling a hearing or conciliation on a complaint, and in its notice of decision, the Commission shall include notice, in plain language, to landlords and tenants that retaliatory actions against tenants are prohibited. C. Any tenant who claims that the action of his or her landlord constitutes retaliatory action may file a notice of such claim with the Commission. If the Commission determines, after a hearing, which hearing shall be expedited, that a landlord has retaliated in any manner against a tenant because the tenant has complained to the Commission, the Commission may order the landlord to cease and desist from such conduct and order the landlord to withdraw or remediate such conduct as has already occurred.
