Connecticut Residential Lease Agreement

• Max 2 months' rent (1 month if the tenant is 62 or older). The deposit is held in escrow and earns interest, paid every year. It must be returned, with an itemized list of any damage deductions, within 21 days after the tenancy ends, or 15 days after the landlord receives the tenant's written forwarding address if that is later (Conn. Gen. Stat. § 47a-21).

• Connecticut has no separate month-to-month termination statute: a periodic tenancy is ended by a notice to quit for 'lapse of time' (§ 47a-23(a)(1)(A)) giving at least three days before the termination of the rental agreement (i.e. served at least three full days before the end of the rental month, with a quit date on or after the period's end).
• Served by a proper officer; statutory form and reason required (§ 47a-23(b)-(c)).

Quoted from the source: “terminates for any of the following reasons: (A) By lapse of time”

Exceptions:

• Protected tenants (§ 47a-23c: age 62+ or disabled, or with such a family member, in a building or complex of five or more units) may be dispossessed only for the causes listed in § 47a-23c(b) — lapse of time alone is not a ground.

• Same lapse-of-time notice to quit as for monthly tenancies: at least three days before the termination of the rental agreement (§ 47a-23(a)); § 47a-23(d) expressly contemplates week-to-week tenancies.

• A tenant remaining after a fixed term ends is removed by the same notice to quit for lapse of time (§ 47a-23(a)(1)(A)) giving at least three days; no separate holdover notice exists.

Quoted from the source: “(A) By lapse of time”

• No general just-cause requirement: lapse of time is a ground for a notice to quit (§ 47a-23(a)(1)(A)).
• Protected tenants only (§ 47a-23c): tenants of a building or complex with five or more units who are 62 or older (or live with such a family member) or have a physical or mental disability expected to last 12+ months may be dispossessed only for nonpayment, refusal of a fair and equitable rent increase, material noncompliance with § 47a-11 or the lease/rules, illegal use, the landlord's permanent removal of the unit from the housing market, or the landlord's bona fide intent to use the unit as a principal residence.

Quoted from the source: “No landlord may bring an action of summary process ... to dispossess a tenant described in subsection (a) ... except for ... the following reasons”

• Notice to quit possession must give at least three days before the termination of the rental agreement or before the time specified in the notice to quit (§ 47a-23(a)); annotations on the official page: the 'at least three days' period excludes both terminal days (day of service and quit date).
• Ground (a)(1)(D): nonpayment of rent within the grace period of § 47a-15a — per the statute text (read on Justia only) nine days after rent is due, four days for a one-week tenancy — so the notice may not be served before the tenth (fifth) day.
• Notice must be in substantially the statutory form, state the address including apartment number, the quit date and the reason in statutory language or words of similar import (§ 47a-23(b)); an attested copy is served by a proper officer (§ 47a-23(c)).
• For month-to-month or week-to-week tenancies a nonpayment notice to quit terminates the agreement for the month/week of delivery and converts the tenancy to one at sufferance (§ 47a-23(d)).

Quoted from the source: “at least three days before the termination of the rental agreement or lease, if any, or before the time specified in the notice”

Exceptions:

• From 2026-01-01 the nonpayment ground does not apply if the landlord's online rental payment system prevented payment within the grace period (§ 47a-23(a)(1)(D), Nov. Sp. Sess. P.A. 25-1 § 37); § 47a-15a extends the grace period five days in that case.

• After the grace period (9 days after the due date; 4 for a week-to-week tenancy; 5 more days in a month or week when the landlord's online payment system prevents payment), one late charge of no more than the lesser of $5 per day up to $50, or 5% of the late rent (Conn. Gen. Stat. § 47a-15a). The statute does not say from which day the $5 per day is counted. Counted from the due date, the limit would be $50 (or 5% of the rent, if less) from day 10.

• Notice to quit of at least three days for nuisance (§ 47a-32) or serious nuisance (§ 47a-15: bodily harm or threats, willful destruction, immediate danger to safety, prostitution or illegal drug sale on the premises) — § 47a-23(a)(1)(G); no § 47a-15 pre-termination notice is required for serious nuisance or § 47a-11(h) violations.
• Same three-day notice for violation of § 47a-11 (ground (F)), occupants who never had a right to occupy ((a)(2)) and whose right has terminated ((a)(3)).
