Connecticut Landlord-Tenant Laws
Local rent regulation in Connecticut
Connecticut has no statute barring local rent regulation; instead it expressly authorizes municipal fair rent commissions — and, since January 1, 2026, requires every municipality of 15,000 or more residents to create or join one — with power to hear complaints and roll back excessive rents. The mandate first applied to municipalities of 25,000 or more in July 2023; under the amended statute every municipality required to have a commission must adopt the ordinance by January 1, 2028, and the commission may be the municipality's own, joint with neighboring towns, or regional.

Connecticut landlord-tenant laws by topic
Connecticut security deposits
Connecticut caps residential security deposits at two months' rent — one month's rent if the tenant is 62 or older, and one month's rent under a mobile home park rental agreement — and requires the deposit to be returned within 21 days after the tenancy ends or 15 days after the landlord receives the tenant's forwarding address in writing, whichever is later.
Connecticut rent increase notice
Connecticut requires written notice of a rent increase at least 45 days before it takes effect, or, for a lease of one month or less, notice equal to one full term, which for a month-to-month tenancy is one full month (47a-4e) — and it MANDATES local fair rent commissions, which since January 1, 2026 every municipality of 15,000 or more people must maintain and which can roll back any rent or proposed increase found 'harsh and unconscionable.'
Connecticut late fees
Connecticut gives residential tenants a statutory 9-day grace period for monthly rent (4 days for week-to-week tenancies) and caps late fees at the lesser of $5 per day up to $50 total, or 5% of the delinquent rent payment.
Connecticut entry notice
Connecticut landlords must give reasonable written or oral notice before entering a rental unit and may enter only at reasonable times — the statute sets no fixed hour count, so charts claiming a 24- or 48-hour Connecticut rule are wrong.
Connecticut eviction process
To evict a tenant in Connecticut a landlord serves a written notice to quit possession giving at least three days, then files a summary process case in Superior Court - but two things come first that catch most people out: for a lease violation a separate 15-day pre-termination notice under CGS 47a-15 must be served and allowed to expire before the notice to quit, and for nonpayment the notice to quit cannot be served until the tenant's nine-day statutory grace period under CGS 47a-15a has run (four days on a week-to-week tenancy, plus five more days if the landlord's own online rent payment system blocked the payment).
Connecticut application & screening fees
Connecticut bans rental application fees outright and allows only one charge at the application stage: a tenant screening report fee of no more than $50, plus an inflation adjustment the Commissioner of Housing determines each year.
Connecticut deposit interest
Connecticut requires every residential landlord to pay interest on a security deposit each year, at not less than the deposit index the Banking Commissioner publishes for that calendar year, which is 0.49% for 2026.
Connecticut habitability & repairs
Connecticut requires a landlord to make all repairs and do whatever is necessary to put and keep the premises in a fit and habitable condition, to comply with the state health code and every applicable building and housing code materially affecting health and safety, to keep common areas clean and safe, to maintain the electrical, plumbing, sanitary, heating and ventilating facilities and the elevators, and to supply running water, reasonable amounts of hot water at all times, and reasonable heat.
Connecticut lease termination
Connecticut has no statute setting a notice period to end a month-to-month tenancy; the tenancy is treated as a run of one-month leases that ends by lapse of time, and the landlord's only obligation is a notice to quit landing at least three days before that lapse.
Connecticut lease disclosures
Since April 1, 2026 every written Connecticut lease must open with the state's completed rental terms summary form as its first page, in English and Spanish.
Connecticut pets & assistance animals
Connecticut has no pet-deposit law and no pet-fee law, so a pet deposit counts inside the ordinary security-deposit cap rather than on top of it.
Connecticut mobile home park laws
Connecticut's mobile manufactured home park law, chapter 412 of the General Statutes, covers a resident who owns the home and rents a lot in any park holding two or more homes: leases run at least a year, a lot-rent increase takes thirty days' written notice, an owner may end a tenancy only on five statutory grounds, and residents must be told when the park is offered for sale and may match the offer.

How this record was verified: Direct read of statute text on the official Connecticut General Assembly site (cga.ct.gov): chapters 830, 831, 832 and 98 downloaded in full from the current-revision pages AND from the 2026 Supplement (revised to January 1, 2026), which carries the 2025-session amendments to Conn. Gen. Stat. 47a-15a, 47a-21, 47a-23 and 7-148b — the supplement text is the operative text used here. Every number that decides an answer here was read at least twice in independent documents: the 2-month/1-month deposit caps, 21-day/15-day return deadline, double-deposit penalty, deposit-index interest rule, 9-day/4-day grace periods, $5-per-day/$50/5%-of-delinquent-payment late-fee cap, and the reasonable-notice entry standard were each confirmed verbatim on the official pages; the 2025 changes (fair-rent-commission threshold 25,000 to 15,000, +5-day online-payment-outage grace extension, rent-algorithm ban) were confirmed in both the 2026 Supplement and the enrolled November Special Session Public Act 25-1 (HB 8002) PDF on cga.ct.gov; the 30-to-21-day deposit-deadline change and late-fee cap were traced to PA 23-207 sections 8, 38 and 39 (effective 2023-10-01) in the enrolled act PDF. The 2026 security-deposit interest rate (0.49% deposit index) was double-read on two official Department of Banking pages. 2026-session sweep: PA 26-79 section 3 (SB 218) read in the enrolled PDF and incorporated when it took effect on October 1, 2026; bill-status pages read for HB 5092, HB 5359, SB 257 and SB 274, all of which died at the 2026-05-06 adjournment. September 5, 2026 addendum: the decisive figures touched by the 2025-2026 enactments reviewed that day were re-read on the official host — §§ 7-148b, 47a-4d, 47a-4f, 47a-15a, 47a-21 and 47a-23 in the 2026 Supplement on cga.ct.gov, with the 2026 public acts; the earlier reads stand as recorded. September 12, 2026 addendum: the security deposit figures in § 47a-21(b), (d), (h), (i), (j) and (k), the § 47a-15a grace periods and late-charge cap, and the § 47a-16 entry standard were re-read on cga.ct.gov (the 2026 Supplement for chapters 830 and 831 and the base revision for § 47a-16); §§ 47a-7c, 47-283 to 47-293 and 1-268 were read there the same day. The earlier reads stand as recorded. October 1, 2026 addendum: the 2026 public acts that took effect that day — P.A. 26-79 § 3 (§ 47a-21(j)(1)), P.A. 26-113 § 1 (§ 47a-4), P.A. 26-11 § 15 (§ 47a-23c) and P.A. 26-77 §§ 15, 16, 26 and 27 (§§ 46a-64 and 46a-64c) — were re-read in the enrolled acts on cga.ct.gov, with § 36a-50 for the civil-penalty ceiling; the General Statutes pages do not yet print them. The same day, every section the security deposit, rent increase, late fee, entry and eviction answers rest on was read again on cga.ct.gov: chapters 98, 412, 828, 830, 831, 832, 833 and 834 in the General Statutes revised to January 1, 2025, and each section the 2026 Supplement reprints in the Supplement. That reading added § 47a-4e (P.A. 24-143, § 17), the rent-increase notice section in force since October 1, 2024, which the rent increase answers had not stated. The Practice Book (2026 edition) and the Judicial Branch's summary process publications were read on jud.ct.gov.
