Connecticut landlord-tenant law.

Updated August 2026. No statewide rent control. Towns and cities with 25,000 or more population must operate a Fair Rent Commission that can order excessive rent increases reduced (Conn. Gen. Stat. § 7-148b, mandatory since July 2023).

Deposit limit

2 months' rent max for tenants under 62, 1 month's rent max for tenants 62 or older, no furnished-unit exception (Conn. Gen. Stat. § 47a-21)

Deposit return

Return deposit plus accrued interest, or a written itemized statement of damages with any balance, within 21 days after the tenancy ends or 15 days after the tenant gives a forwarding address, whichever is later. Violation lets the tenant recover double the amount wrongfully withheld (Conn. Gen. Stat. § 47a-21(d)).

Notice to pay

Landlord must let the 9 day rent grace period expire (4 days for a weekly tenancy) before serving a Notice to Quit, which then must give the tenant at least 3 more days before an eviction action can be filed, roughly 12 days total for a monthly tenancy (Conn. Gen. Stat. §§ 47a-15a, 47a-23).

Landlord entry

Landlord must give reasonable written or oral notice and may enter only at reasonable times except in an emergency, for inspection, repairs, agreed services, or showing the unit to a prospective purchaser, mortgagee, tenant, or worker; the statute does not set a specific number of hours or days for what counts as reasonable (Conn. Gen. Stat. § 47a-16).

Security deposits

Deposit limit. 2 months' rent max for tenants under 62, 1 month's rent max for tenants 62 or older, no furnished-unit exception (Conn. Gen. Stat. § 47a-21)

Getting it back. Return deposit plus accrued interest, or a written itemized statement of damages with any balance, within 21 days after the tenancy ends or 15 days after the tenant gives a forwarding address, whichever is later. Violation lets the tenant recover double the amount wrongfully withheld (Conn. Gen. Stat. § 47a-21(d)).

Late fees and rent

No late charge may be imposed until the 9 day rent grace period runs out (4 days for a week to week tenancy), and the charge itself is capped at the lesser of $5 per day up to $50, or 5 percent of the delinquent rent, with only one charge allowed per late payment (Conn. Gen. Stat. §§ 47a-15a, 47a-4).

Ending a tenancy

Nonpayment of rent. Landlord must let the 9 day rent grace period expire (4 days for a weekly tenancy) before serving a Notice to Quit, which then must give the tenant at least 3 more days before an eviction action can be filed, roughly 12 days total for a monthly tenancy (Conn. Gen. Stat. §§ 47a-15a, 47a-23).

Month-to-month termination. The statute sets a general 3 day Notice to Quit for ending any tenancy, including by lapse of time for a month to month tenancy (Conn. Gen. Stat. § 47a-23), but it does not spell out a separate advance notice period equal to a full rental month before that quit notice for a no cause termination; in practice landlords generally give at least one rental period's notice first, and this specific point is not fully settled by statute alone. Tenants 62 or older or with disabilities in buildings of 5 or more units get added good cause eviction protection and must receive written notice of those rights (Conn. Gen. Stat. § 47a-23c, as amended effective January 1, 2024).

Landlord entry

Landlord must give reasonable written or oral notice and may enter only at reasonable times except in an emergency, for inspection, repairs, agreed services, or showing the unit to a prospective purchaser, mortgagee, tenant, or worker; the statute does not set a specific number of hours or days for what counts as reasonable (Conn. Gen. Stat. § 47a-16).

Required disclosures

  • Federal lead-based paint disclosure for units built before 1978 (42 U.S.C. § 4852d)
  • Written identification, before the tenancy starts, of the person authorized to manage the premises and the person authorized to receive legal notices (Conn. Gen. Stat. § 47a-6)
  • For tenants 62 or older or with disabilities in buildings of 5 or more units, a state prescribed plain language notice of good cause eviction and rent protections (Conn. Gen. Stat. § 47a-23c, effective January 1, 2024)
  • Annual statement of security deposit interest earned, paid, or credited on the tenancy anniversary (Conn. Gen. Stat. § 47a-21)

Lease clauses that do not hold up

  • Waiver of tenant rights or remedies under the landlord tenant statutes
  • Confession of judgment clauses
  • Exculpatory clauses limiting or waiving landlord liability, or requiring the tenant to indemnify the landlord
  • Self-help eviction or distraint of property consent, attorney's fee shifting above 15 percent of any judgment, and late fees charged before the statutory grace period or above the statutory cap (Conn. Gen. Stat. § 47a-4)

Notes for landlords

Connecticut voids confession of judgment clauses outright, a stronger tenant protection than most states. A 2024 amendment requires landlords in buildings of 5 or more units to give written good cause eviction notices to tenants who are 62 or older or disabled, and larger towns must run Fair Rent Commissions that can roll back excessive rent hikes even without statewide rent control.
