Conn. Gen. Stat. § 47a § 47a-13a
Implementation of energy conservation measures by tenant.
Operative Text
(a) A tenant of any dwelling unit may, in accordance with subsection (b) of this section, at no cost to the landlord, implement or authorize the implementation of energy conservation measures in his dwelling unit or in any other part of the building which affects the tenant's level of energy consumption, which would otherwise require the consent of the landlord. (b) In order to implement energy conservation measures under this section, the tenant or entity administering any energy conservation or weatherization program shall give written notice of the intent to implement such measures to the landlord by certified mail, return receipt requested. Unless the landlord gives written notice of his disapproval of such implementation by certified mail, return receipt requested, within twenty days of the giving of notice to him, such energy conservation measures may be implemented, provided that, to the extent his consent would otherwise be necessary, no such disapproval shall be effective as to the installation of removable weatherstripping around doors and windows, removable interior storm windows and insulation wrap around hot water heating tanks. (c) Nothing in this section shall (1) authorize the tenant to make structural changes to the building; (2) relieve the tenant or the landlord of their responsibilities and liabilities under sections 47a-7 and 47a-11; or (3) restrict the availability to the tenant of any other remedies which exist under any other law.
Under Conn. Gen. Stat. § 47a-13a, Connecticut tenants have a conditional right to implement energy conservation measures—such as removable weatherstripping, interior storm windows, or hot water tank insulation wrap—in their dwelling units or building areas affecting their energy use, without needing prior landlord approval in all cases. The process requires written notice to the landlord by certified mail; if the landlord does not object in writing within twenty days, the measures may proceed. Certain removable improvements cannot be blocked by landlord disapproval, and the provision does not permit structural changes or alter either party's existing maintenance responsibilities.
Plain English — not legal advice.
Conn. Gen. Stat. § 47a-13a gives tenants or weatherization program administrators the ability to move forward with qualifying energy conservation measures after providing certified-mail notice, so landlords who receive such notice generally have a twenty-day window to submit a written disapproval by certified mail. Compliant operators typically track incoming notices carefully and respond within that window if they have legitimate objections, while recognizing that disapproval cannot block certain removable items like weatherstripping or interior storm windows. Landlords bear no cost under this provision, and their existing obligations under § 47a-7 remain in effect.

Conn. Gen. Stat. § 47a-13a gives Connecticut tenants the ability to install qualifying energy conservation measures—at no cost to the landlord—by sending written notice to the landlord via certified mail and waiting twenty days for any objection. Removable weatherstripping, interior storm windows, and hot water tank insulation wrap cannot be blocked by a landlord's disapproval. Tenants who believe their rights under this provision have been violated may consult a tenant-rights organization or explore other remedies preserved by subsection (c).
