As a Connecticut real estate attorney with over 12 years drafting landlord-tenant documents and representing both property owners and renters across Hartford, New Haven, Fairfield, and Litchfield counties, I’ve helped hundreds of clients properly end month-to-month tenancies without unnecessary court battles or financial penalties. Ending a month-to-month lease in Connecticut is governed by clear statutory rules, but small mistakes in notice timing or delivery method frequently lead to disputes. This comprehensive guide explains every step under current Connecticut landlord-tenant law for month-to-month leases, and I’m providing my battle-tested, attorney-drafted Connecticut 30-Day Notice to Quit (Month-to-Month Tenancy) template completely free at the end.
In Connecticut, a month-to-month lease is technically a periodic tenancy that automatically renews each month unless properly terminated. Connecticut General Statutes § 47a-23 requires at least 30 days written notice from either the landlord or the tenant to end a month-to-month tenancy when the rent is paid monthly – the most common scenario.
Important: The 30-day notice period is calculated by calendar days, not “rent cycles.” If notice is served on October 15, the tenancy ends no earlier than November 14 (30 days later), regardless of when rent is normally due.

If you are a landlord reading this, be aware that after a tenant has lived in the unit for one year or more, Connecticut law dramatically limits “no-cause” terminations. You generally may only end the tenancy for one of the reasons listed in Conn. Gen. Stat. § 47a-23(a), such as nonpayment of rent, serious nuisance, or refusal to sign a new lease on reasonable terms. Pure month-to-month “I just want the unit back” notices are no longer allowed after 12 months without just cause.

This template includes:
Connecticut law requires landlords to return the security deposit (or an itemized list of deductions) within 15 days after the tenant provides a forwarding address, or within 30 days of lease termination, whichever is earlier (Conn. Gen. Stat. § 47a-21(d)). Include your new mailing address in the notice template to start the clock.
Can I give notice mid-month?
Yes. The tenancy ends 30 days after delivery, even if that falls mid-month.
Does the landlord have to accept my notice?
Yes. Once proper notice is given, the tenancy terminates automatically.
What if my lease says 60 days notice is required?
That provision is unenforceable for month-to-month tenancies under Connecticut law. State statute controls.
Can I email the notice?
Only if your written lease explicitly permits electronic delivery.
