How long does a landlord have to return a security deposit in Connecticut?
In Connecticut, the deadline is 21 days after move-out (or 15 days after receiving forwarding address, whichever is later). That clock runs from move-out and the return of possession, not from the end of the lease.
Connecticut law sets the maximum deposit at 2 months' rent (tenants under 62); 1 month (tenants 62+).
Missing the deadline has teeth. Across states, remedies range from losing the right to any deduction to penalty damages plus the tenant's attorney's fees. The itemized deduction statement has to arrive inside the same window to preserve any deduction at all.
