How it's counted: Before the end of the current monthly term (Connecticut month-to-month tenancies run as successive monthly terms).
How the deadline actually works in Connecticut
DESCRIPTIVE-CITATION-ONLY STATE (PA/NJ pattern). Connecticut law does not specify a notice period for tenants ending a month-to-month tenancy — the rental agreement's stated period controls, and 30 days before the end of the monthly term is the safe default. Context: since Oct 2024, landlords owe month-to-month tenants 45 days' notice before rent increases — asymmetry in the tenant's favor on changes.
Worked example: rent due on the 1st, written notice delivered June 10. The earliest compliant termination date is July 31, 2026 — notice must clear the required period and land on a rental-period boundary, which is the step most people miss. Our generator computes this date from your actual rent schedule.
Your lease can require more
State law is the floor, not the ceiling. If your lease requires more notice than the statute (60 days is common in larger complexes), the longer period controls. Read the termination or notice clause before sending anything — a proper letter satisfies both requirements at once.
What notice does your landlord owe you?
The other direction matters too: a Connecticut landlord ending a month-to-month tenancy generally owes the tenant 3-day notice to quit (summary process); just-cause protections for protected tenants in larger buildings (Conn. Gen. Stat. § 47a-23 / § 47a-23c). Protected tenants (62 or older, or with disabilities) in buildings of five or more units have just-cause eviction protections (§ 47a-23c).
Deliver it so it counts
Use a method that creates a record: hand delivery with a signed acknowledgement, or certified mail with return receipt. If your lease names a required delivery method, use that one. Keep a copy of the letter and the receipt — together they are your proof that notice was proper and on time.
