How long does a landlord have to return a security deposit in Connecticut?
In Connecticut, a landlord has 21 days after the tenancy ends to return the security deposit, together with an itemised statement of any deductions. 21 days from termination or 15 days from receiving a forwarding address, whichever is later. Connecticut also requires interest to be paid on the deposit: Interest at the Banking Commissioner's published rate, paid annually. This is Conn. Gen. Stat. § 47a-21.
