Connecticut month-to-month lease agreement
Written for Connecticut law, checked September 24, 2026 General information, not legal advice
A month-to-month tenancy renews each month until the landlord or the tenant gives notice. Choose month-to-month as the lease type, or set a fixed-term lease to convert to month-to-month when its term ends.
Connecticut rules that apply
Ending a month-to-month tenancy
Partly readA tenancy without a fixed term is month to month, or week to week when rent is paid weekly. To end it, the landlord serves a notice to quit that gives at least three days before the quit date. This page did not find a longer notice period for ending a month-to-month tenancy, but not every section of the eviction chapter was read.
Conn. Gen. Stat. § 47a-3b Conn. Gen. Stat. § 47a-23(a)
More detail (2)
- Staying after a lease ends is not by itself evidence of a new lease. Conn. Gen. Stat. § 47a-3d
- A tenant 62 or older, or with a qualifying disability, in a building or complex of five or more units can be evicted only for listed good causes, such as nonpayment or a material violation. Conn. Gen. Stat. § 47a-23c(a), (b) See Eviction process on the Connecticut page
The Rentari Connecticut lease says either party may end a month-to-month tenancy, that the landlord's notice to quit gives at least three days, and that Connecticut sets no separate longer notice.
Rent increase notice
A rent increase takes effect only if you gave the tenant written notice at least 45 days before it starts. For a lease with a term of one month or less, the notice must be as long as one full term. A tenant's failure to respond is not agreement to the increase.
More detail (5)
- The notice rule does not let a landlord raise rent during the term of a lease. Conn. Gen. Stat. § 47a-4e
- It applies to leases entered into, renewed or extended on or after October 1, 2024. Conn. Gen. Stat. § 47a-4e
- A landlord may not demand a rent increase within six months after a tenant's protected complaint or repair request, with narrow exceptions. Conn. Gen. Stat. § 47a-20 Conn. Gen. Stat. § 47a-20a(b) See Retaliation on the Connecticut page
- Tenants 62 or older or with a disability, in buildings of five or more units, may have increases limited to what is fair and equitable. Conn. Gen. Stat. § 47a-23c(c) See Rent control and local rules on the Connecticut page
- Prepare a rent-change record with the tenancy term, current rent, proposed rent, dollar difference and proposed effective date. Address the letter to the tenants at the correct unit, allow the applicable notice period and explain how they can respond or discuss a renewal. Keep the letter, delivery record and actual response together; silence is not acceptance. Check any fair-rent commission process or protected-tenancy issue separately, and record an agreed renewal before changing the payment schedule for its effective date. Conn. Gen. Stat. § 47a-4e Conn. Gen. Stat. § 7-148b(b), (c)
The Rentari Connecticut lease states the 45-day written notice, the full-term notice for a lease of a month or less, that silence is not agreement, and that the lease permits no increase during its term. Rentari's rent increase notice uses 45 days for Connecticut.
