Connecticut Eviction Notice Law
Connecticut's notice period for unpaid rent is 3 days (Notice to quit for nonpayment (served after the 9-day grace period)). For a lease violation it is 15 days, and the tenant gets a chance to fix the problem.

What Connecticut law says
What notice must a Connecticut landlord give before filing an eviction for unpaid rent?
If rent is still unpaid nine days after it was due (four days for a weekly tenancy), the landlord may have a state marshal serve a notice to quit that gives at least three full days to leave, with the Right to Counsel notice attached (Conn. Gen. Stat. §§ 47a-15a(a), 47a-23(a), 47a-75(f)(2)) (Conn. Gen. Stat. § 47a-15a(a) (2026 Supplement)).
How much notice is required for a lease violation in Connecticut?
For a material lease violation, deliver a written notice naming the breach and a termination date at least 15 days after receipt; a repairable breach fixed, or damages paid, within those 15 days keeps the lease alive, but a repeat within six months or a serious nuisance allows a notice to quit with no cure period (Conn. Gen. Stat. §§ 47a-15, 47a-23(a)) (Conn. Gen. Stat. § 47a-15).
How much notice ends a month-to-month tenancy in Connecticut?
No Connecticut statute sets how much notice a tenant must give to end a month-to-month tenancy, so follow the lease; a landlord ends one by having a marshal serve a notice to quit for lapse of time that gives at least three full days and runs to the end of the rental month (Conn. Gen. Stat. §§ 47a-3b, 47a-23(a)) (Conn. Gen. Stat. § 47a-23(a)).

Local rules in Connecticut
Every Connecticut municipality with 15,000 or more residents must create or join a fair rent commission by January 1, 2028 (Conn. Gen. Stat. § 7-148b); a commission can limit a rent or increase it finds harsh and unconscionable. Tenants who are 62 or older or disabled (or live with such a family member) and live in a building of five or more units or a mobile home park can be evicted only for good cause (§ 47a-23c).
