Connecticut notice periods
A Connecticut landlord must give 3 days’ written notice to end a month-to-month tenancy. A rent increase needs 30 days’ notice. For nonpayment, the landlord must serve a 3-day notice to pay or quit before filing for eviction.
The Connecticut rules in detail
Connecticut has no separate statutory notice period for ending a month-to-month tenancy. A landlord ends it by serving a notice to quit for lapse of time at least 3 full days before the quit date, and per the Judicial Branch's summary-process guide the quit date must also be no earlier than the end of the current rental month. No statute sets a tenant's notice period; the common-law rule of one full rental period applies (UNVERIFIED in statute).
For a lease with a term of one month or less (month-to-month), notice equal to one full term, i.e., one month; for longer leases, at least 45 days' written notice before the increase takes effect (§ 47a-4e, PA 24-143, effective Oct 1, 2024, applicable to agreements entered, renewed or extended on or after that date). Tenant silence is not agreement.
3 days. The tenant may cure by paying everything owed within the period; after that the landlord may file for eviction.
Serving the notice
- Notice must be in writing. Text messages and emails count only where the lease or statute allows electronic notice.
- The clock starts when the notice is delivered, not when it is written. Mailed notices usually add days; check the statute’s service rules.
- Termination notices generally take effect at the end of a rental period. Served mid-month, a 30-day notice ends the tenancy at the end of the next full month.
- A fixed-term lease ends on its own date; these periods apply to month-to-month tenancies and to tenancies that continued after a lease expired.

- Late fees: No late charge until rent is more than 9 days late (4 days for a week-to-week tenancy). The charge may not exceed the lesser of (1) $5 per day up to a maximum of $50, or (2) 5% of the delinquent rent (5% of the tenant's share if rent is subsidized). Only one late charge per delinquent payment regardless of how long it remains unpaid; a lease clause contrary to these limits is unenforceable (§ 47a-4(a)(8)-(9)). Added by PA 23-207, effective Oct 1, 2023.

How long is a pay-or-quit notice in Connecticut?
3 days. The tenant can stop the eviction by paying the full amount within that time.
Does the notice have to end on the last day of the month?
In most states, yes: a termination notice on a periodic tenancy takes effect at the end of a rental period that is at least the required number of days after service. Serving on the 15th with a 30-day requirement typically ends the tenancy at the end of the following month, not 30 days later. The calculator shows both dates.
