Connecticut specific notes

Connecticut's 9-day grace period (before a notice to quit can even be issued) is one of the longest in the country. Deposit must be held in an escrow account; landlord must pay interest annually. The 30-day return deadline starts from the date the tenant vacates and provides a forwarding address.
