Connecticut legal context

Connecticut has strong tenant protections. Security deposits are capped at two months' rent (one month for tenants 62+) under Conn. Gen. Stat. § 47a-21, and must be returned within 30 days (or 15 days after receiving forwarding address, whichever is later) with interest. Connecticut requires just-cause eviction for many tenancies and a 9-day cure-or-quit notice for nonpayment. Some municipalities (e.g., Hartford) have rent stabilization.
