What does Connecticut law require a landlord to repair?

Verified August 29, 2026 All Connecticut topics →

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.

A tenant who gives written notice of the breach may terminate if it is not remedied within fifteen days — a deadline to finish the cure, not to start it — and a recurrence within six months allows termination on fourteen days' notice. Connecticut has no general repair-and-deduct: the only deduct right, in § 47a-13, covers essential services, where the tenant may buy the missing heat, water, hot water, electricity or gas and deduct the actual cost with no cap, and may move to substitute housing after forty-eight hours, or immediately if the same service failed within the previous six months. Rent is where the leverage sits — a rental agreement may not permit the receipt of rent for any period the landlord failed to comply, and a tenant may instead sue under § 47a-14h and pay rent to the court clerk, but only after complaining to the municipal housing-code agency at least twenty-one days earlier. Retaliation within six months of a protected act is presumed and can be rebutted only on four exclusive grounds, though the statute gives the tenant a defence rather than a lawsuit of the tenant's own.

Connecticut habitability & repairs at a glance

Where the duty comes from Statute — no independent court-created warranty operates alongside it
Duty source details The duty is entirely statutory. Conn. Gen. Stat. § 47a-7(a) states six landlord responsibilities, and every Connecticut remedy is likewise statutory — the rent-collection bar in § 47a-4a, termination in § 47a-12, essential services in § 47a-13, the tenant's enforcement action in § 47a-14h, and the retaliation provisions in §§ 47a-20 and 47a-33. There is no separate court-made warranty operating alongside them: the Connecticut Supreme Court held in Johnson v. Fuller (1983) that in general there is no implied warranty of habitability given to a tenant, restated that rule in Gore v. People's Savings Bank (1995), and in Ossen v. Wanat (1991) used the phrase 'implied warranty of habitability' as a label for the § 47a-4a statutory defense itself. A Connecticut tenant can and does plead breach of the warranty — the warranty is the statute.
Who is covered Statewide — no coverage split
Where the repair standards live The statute itself lists specific standards
What must be kept in repair Section 47a-7(a) lists six duties: comply with chapter 368o and all applicable state and local building and housing codes materially affecting health and safety; make all repairs and do whatever is necessary to put and keep the premises in a fit and habitable condition, except where the tenant, a family member or a person on the premises with the tenant's consent intentionally rendered them unfit, in which case the duty shifts to the tenant; keep all common areas clean and safe; maintain in good and safe working order all electrical, plumbing, sanitary, heating, ventilating and other facilities and appliances AND elevators, supplied or required to be supplied by the landlord; provide and maintain appropriate receptacles for ashes, garbage, rubbish and other waste and arrange for their removal; and supply running water and reasonable amounts of hot water at all times and reasonable heat. Section 47a-7(b) settles the interaction with local law in the tenant's favour: where a municipal ordinance, building code or fire code imposes a greater duty than subsection (a), that provision takes precedence over the lesser state duty.
Heat standard type A duty to supply heat or maintain temperatures while the unit is occupied
Heat standard details Connecticut states the duty as a supply obligation but attaches no temperature figure and no season: the landlord must supply running water and reasonable amounts of hot water at all times and reasonable heat. Three exceptions are written into the same subdivision — the duty does not apply where the building is not required by law to be equipped for that purpose, where the unit is so constructed that heat or hot water is generated by an installation within the tenant's exclusive control, or where it is supplied by a direct public utility connection. A municipal ordinance or building or fire code that imposes a greater duty takes precedence, so local heat rules, where they exist, set the operative figure.
Headline repair day count 15 days
Notice and repair-window rules Fifteen days is a clock to COMPLETE the cure, not to begin work. Where there is material noncompliance by the landlord with the rental agreement, or noncompliance with § 47a-7 that materially affects health and safety, the tenant delivers written notice specifying the acts and omissions constituting the breach, and if the breach is not remedied within fifteen days after receipt the rental agreement terminates on that date. A recurrence changes the sequence: if substantially the same act or omission recurs within six months of the first, the tenant may terminate on at least fourteen days' written notice stating the date the breach occurred and the date the tenant will vacate, which must be within thirty days of the breach. Two limits catch people out — § 47a-12 does not apply at all to tenancies of one month or less, and it is unavailable for a condition caused by the wilful or negligent act or omission of the tenant, a family member or a person on the premises with the tenant's consent. Essential services run on a different and much faster track that accepts reasonable written OR ORAL notice, and § 47a-4a — the rule that a rental agreement may not permit the receipt of rent for any period during which the landlord failed to comply with § 47a-7(a) — states no notice period or cure window at all.
Repair and deduct Only for essential-service failures, not general repairs — Limit: Where the remedy applies it is uncapped: the tenant deducts the actual and reasonable cost of the service procured, with no dollar ceiling, no fraction-of-rent limit and no cap on how often it may be used. There is no general repair-and-deduct remedy for ordinary repairs anywhere in the Connecticut statutes. — Section 47a-13(a)(1) is the only deduct route, and it reaches services rather than repairs. Where the landlord is required to supply heat, running water, hot water, electricity, gas or another essential service and fails to do so, and the failure is not caused by conditions beyond the landlord's control, the tenant gives notice specifying the breach and may procure reasonable amounts of the missing service during the period of noncompliance and deduct the actual and reasonable cost from rent. Notice may be reasonable written or oral notice — the rights do not arise until it is given. The remedy is unavailable where the condition was caused by the wilful or negligent act or omission of the tenant, a family member or another person on the premises with the tenant's consent. For an ordinary unrepaired condition a Connecticut tenant's routes are the § 47a-4a rent bar, the § 47a-12 termination sequence, and the § 47a-14h enforcement action — not self-help repair.
Rent withholding or escrow Yes — at least one lawful path exists — How: withholding on the tenant's own action, no court filing first; a court or agency escrow program — Two shapes operate side by side. The first is § 47a-4a: a rental agreement shall not permit the receipt of rent for any period during which the landlord has failed to comply with § 47a-7(a). The Appellate Court has described this as the tenant's right to withhold the rental payment, and in practice it is asserted as a special defence when the landlord sues for possession or for rent; the protection is not invoked unless the condition is a substantial one — a request for repairs that is not necessary to maintain the premises in a fit and habitable state does not trigger it. The second is the § 47a-14h enforcement action, a court rent-deposit programme. The tenant sues in the superior court having jurisdiction over housing matters in the judicial district where the tenant lives, and must allege that AT LEAST TWENTY-ONE DAYS before filing the tenant complained about the premises to the municipal agency responsible for enforcing the housing code — or the public health code where no housing code exists — a precondition the Supreme Court has held mandatory. The entry fee is twenty-five dollars, waivable, and no recognizance or bond is required; multiple tenants from one building filing the same day are treated as a single action; the hearing is set for not more than fourteen days after filing or return of service, and the enforcement agency submits its inspection report to the court. On each rent due date thereafter, or within nine days (four days for a week-to-week tenancy), the tenant deposits the last agreed-upon rent with the clerk — payment to the clerk is for all purposes the equivalent of paying the landlord, and no landlord may maintain a possession action for nonpayment once the clerk has an amount equal to the rent due. Failure to deposit can bring dismissal of the complaint. The court may order the landlord to comply, appoint a receiver to collect rent or correct conditions, stay other proceedings on the same property, award damages including a retroactive abatement of the rent deposited, and direct that the accrued deposits be used for the repair of the building. The action is closed off if a valid notice to quit for nonpayment was served before it was brought, and the landlord may move at any time to end the payments into court once the § 47a-7 violations are corrected.
Termination over habitability failures Yes — a statute states the right — Written notice of the acts and omissions constituting the breach starts the fifteen-day cure period, and if the breach is not remedied the rental agreement terminates on that date — the termination is automatic on the date rather than something the tenant must separately declare. On a recurrence of substantially the same act or omission within six months, the tenant terminates on at least fourteen days' written notice with a vacating date within thirty days of the breach. Neither route is available for a condition the tenant, a family member or a consented person caused wilfully or negligently, and neither reaches a tenancy of one month or less. A wilful failure to supply an essential service opens a separate and stronger termination right under § 47a-13(a)(3): the tenant may terminate and recover an amount not more than two months' periodic rent or double the actual damages sustained, whichever is greater, and on termination the landlord must return all security and prepaid rent with the interest the deposit law requires.
Essential-service remedies Yes — distinct statutory remedies for essential-service failures — Section 47a-13 gives essential-service failures their own remedy set and their own notice rule. It applies where the landlord is required to supply heat, running water, hot water, electricity, gas or another essential service and fails, and the failure is not caused by conditions beyond the landlord's control. Reasonable written OR ORAL notice to the landlord is enough to make the rights arise. The tenant may then elect one of three things: procure reasonable amounts of the missing service during the noncompliance and deduct the actual and reasonable cost from rent; procure reasonable substitute housing if the landlord has not supplied the service within FORTY-EIGHT HOURS of the breach — and immediately, with no waiting period, if the same service failed before and the failure recurs within six months; or, where the failure is wilful, terminate the rental agreement and recover not more than two months' periodic rent or double the actual damages, whichever is greater. A tenant who moves to substitute housing has the rent abate for the period of noncompliance and recovers the actual cost of that housing, but never more than the amount of rent abated. Reasonable attorney's fees are recoverable in any cause of action OR DEFENCE arising under the subsection. The rights do not arise where the condition was caused by the wilful or negligent act or omission of the tenant, a family member or a person on the premises with the tenant's consent.
Retaliation protection Protected by a general retaliation statute — Six months. Where the landlord acts within six months of the tenant's protected act, § 47a-20 raises a rebuttable presumption of retaliation, and the landlord may rebut it only on one of the four grounds § 47a-20a makes exclusive — the Appellate Court has held that a landlord who proves none of the four has not rebutted the presumption. — Connecticut's protection is a shield rather than a sword. Section 47a-20 operates as a limitation on the landlord's remedies — the Appellate Court has held that its language confers no private cause of action, so a tenant cannot sue on it. Inside the six months a prima facie case raises a rebuttable presumption of retaliation which the landlord can answer only through the four exclusive grounds of § 47a-20a(a); § 47a-20a(b) adds two rent-increase carve-outs, for a tenant's lack of due care and for a substantial increase in property taxes or other maintenance or operating costs incurred not less than four months before the demand, with the increase limited to the prorated portion of the net increase. Section 47a-33 is a separate and differently built protection: in any summary process action it is an affirmative defence that the landlord brought the action SOLELY because the tenant tried by lawful means to remedy a condition violating the law — sole causation, with no presumption, the tenant bearing the burden of persuasion, and a final sentence expressly preserving the tenant's obligation to pay rent or the reasonable value of use and occupancy. Section 47a-33a separately allows a tenant to raise any affirmative legal, equitable or constitutional defence in a summary process action. — Section 47a-20 lists five protected tenant actions; the one this topic turns on is a request for repairs, and the Appellate Court has held the protection is not invoked unless the repair requested is necessary to maintain the premises in a fit and habitable state, so minor requests do not trigger it. Section 47a-33's defence protects a tenant who attempted by lawful means — including contacting officials of the state or of any town, city, borough or public agency, or filing a complaint with a fair rent commission — to remedy any condition violating chapter 368o, chapter 412, another state statute or regulation, or the housing or health ordinances of the municipality where the premises are.
Damages, penalties, and defenses Money remedies in Connecticut sit mostly in the essential-services and enforcement sections rather than in a general damages provision. A wilful failure to supply an essential service brings not more than two months' periodic rent or double the actual damages, whichever is greater, plus return of all security and prepaid rent with interest on termination; a tenant who takes substitute housing recovers its actual cost but never more than the rent abated; and reasonable attorney's fees are recoverable in any action or defence arising under § 47a-13(a). The § 47a-14h action can produce a compliance order, a receiver appointed to collect rent or correct conditions, a stay of other proceedings on the property, money damages including a retroactive abatement of the rent held by the clerk, and an order that the accrued deposits be spent on repairing the building. Two lease-term limits are worth knowing: § 47a-4(a)(7) caps a tenant's promise to pay the landlord's attorney's fees at fifteen per cent of any money judgment against the tenant, and § 47a-4(a)(3) voids any exculpation of the landlord or tenant indemnity for the landlord's liability. The landlord's defences: the § 47a-7(a)(2) duty itself shifts to the tenant where the tenant, a family member or a consented person intentionally rendered the premises unfit or uninhabitable; § 47a-12(b) and § 47a-13(c)(2) both remove the tenant's remedy where the condition was caused by the wilful or negligent act or omission of the tenant's side; § 47a-13(a) does not apply where the service failure is caused by conditions beyond the landlord's control; § 47a-12 does not reach tenancies of one month or less; and in a § 47a-14h action the landlord may counterclaim for an order compelling the tenant to comply with the tenant's own duties under § 47a-11.
Can the duty be waived or shifted A delegation provision reaches beyond the usual single-family limits
Waiver and delegation rules Section 47a-4(a)(1) is the anti-waiver rule and it is chapter-wide: a rental agreement may not provide that the tenant agrees to waive or forfeit rights or remedies under this chapter and a long list of related sections, or under any general statute or municipal ordinance, unless that section or ordinance expressly says the rights may be waived. Section 47a-4(a)(3) separately voids any exculpation or limitation of the landlord's liability and any tenant indemnity for it, and a prohibited provision included in a rental agreement is unenforceable. Two delegation carve-outs are the express exception, and Connecticut's second one is unusually wide. Under § 47a-7(c) the landlord and tenant OF A SINGLE-FAMILY RESIDENCE may agree in writing that the tenant performs the waste-receptacle and water-hot-water-heat duties and also specified repairs, maintenance tasks, alterations or remodeling, provided the transaction is in good faith and not to evade the landlord's obligations. Under § 47a-7(d) the parties to any OTHER dwelling unit may agree that the tenant performs specified repairs, maintenance tasks, alterations or remodeling on four conditions: good faith, a writing, no diminishing of the landlord's obligation to other tenants in the premises, and — the one that matters most — the work may not be necessary to cure noncompliance with the code duty or the fit-and-habitable duty. So in a multi-unit building the core habitability duty cannot be shifted to a tenant at all.
Leading court decisions Johnson v. Fuller, 190 Conn. 552, 461 A.2d 988 (1983) — Rejected a claim that the landlord had breached an implied warranty of habitability running with the premises, restating the Connecticut rule that in general there is no implied warranty of habitability given to a tenant, who takes the premises as found and bears the risk of defective conditions within the area under the tenant's exclusive possession and control. The exception the court preserved is narrow: defects resulting from faulty design or disrepair that existed at the beginning of the tenancy, were not discoverable by the tenant on reasonable inspection, and were actually or constructively known to the landlord. The same passage holds §§ 47a-4a and 47a-7 inapplicable to a commercial use. • Gore v. People's Savings Bank, 235 Conn. 360, 665 A.2d 1341 (1995) — Restated the same negative twelve years later, recognising that at common law there is no implied warranty of habitability given to a tenant, who takes the premises as found and bears the risk of defective conditions within the tenant's exclusive possession and control, and quoting Johnson v. Fuller for it. The decision's other references to a warranty of habitability quote the Restatement and an out-of-state decision rather than stating Connecticut law. • Ossen v. Wanat, 217 Conn. 313, 585 A.2d 685 (1991) — Attributed the tenant's habitability defence to statute rather than common law: statutory modifications have created new rights and remedies, and a tenant may now plead by way of special defence that the landlord breached an implied warranty of habitability, or that the claim for possession is retaliatory. The court's own footnote identifies that warranty as Conn. Gen. Stat. § 47a-4a, and the retaliation footnote as § 47a-33 — so the phrase names the statutory defences rather than a separate common-law doctrine. • Visco v. Cody, 16 Conn. App. 444, 547 A.2d 935 (1988) — Held on an issue of first impression that the protection of § 47a-20 is not invoked unless the repair the tenant requested is necessary to maintain the premises in a fit and habitable state, so good-faith requests for minor repairs do not bring the retaliation provision into play. The opinion also sets out the shape of the Connecticut remedy set: the tenant may withhold the rental payment under § 47a-4a, may bring an action under § 47a-14h to compel the landlord to perform legal duties, or may interpose the landlord's noncompliance as a defence in a summary process action under §§ 47a-20 and 47a-33.
Local rules Local law can raise the standard and never lowers it. Section 47a-7(b) provides that where a municipal ordinance, building code or fire code requires a greater duty of the landlord than § 47a-7(a) does, that provision takes precedence over the lesser state duty — so the town or city code is the operative standard wherever it is stricter. Local enforcement is also built into the tenant's main court remedy: a § 47a-14h action requires a complaint made at least twenty-one days earlier to the municipal agency responsible for enforcing the housing code, or the public health code where the municipality has no housing code, and that agency must submit its inspection report to the court at the hearing. Fair rent commissions appear in the § 47a-33 defence as one of the lawful routes a tenant may take to remedy a condition.

Each answer is the verified value from the table above, restated as a direct answer. Free to quote with a link to this page.

Does Connecticut have an implied warranty of habitability?
Statute — no independent court-created warranty operates alongside it. The duty is entirely statutory. Conn. Gen. Stat. § 47a-7(a) states six landlord responsibilities, and every Connecticut remedy is likewise statutory — the rent-collection bar in § 47a-4a, termination in § 47a-12, essential services in § 47a-13, the tenant's enforcement action in § 47a-14h, and the retaliation provisions in §§ 47a-20 and 47a-33.
How long does a landlord have to make repairs in Connecticut?
15 days. Fifteen days is a clock to COMPLETE the cure, not to begin work. Where there is material noncompliance by the landlord with the rental agreement, or noncompliance with § 47a-7 that materially affects health and safety, the tenant delivers written notice specifying the acts and omissions constituting the breach, and if the breach is not remedied within fifteen days after receipt the rental agreement terminates on that date.
Can a tenant repair and deduct in Connecticut?
Only for essential-service failures, not general repairs — Limit: Where the remedy applies it is uncapped: the tenant deducts the actual and reasonable cost of the service procured, with no dollar ceiling, no fraction-of-rent limit and no cap on how often it may be used. There is no general repair-and-deduct remedy for ordinary repairs anywhere in the Connecticut statutes. — Section 47a-13(a)(1) is the only deduct route, and it reaches services rather than repairs.
Can a tenant withhold rent for repair problems in Connecticut?
Yes — at least one lawful path exists — How: withholding on the tenant's own action, no court filing first; a court or agency escrow program — Two shapes operate side by side. The first is § 47a-4a: a rental agreement shall not permit the receipt of rent for any period during which the landlord has failed to comply with § 47a-7(a).
Can a landlord retaliate against a tenant who complains about repairs in Connecticut?
Protected by a general retaliation statute — Six months. Where the landlord acts within six months of the tenant's protected act, § 47a-20 raises a rebuttable presumption of retaliation, and the landlord may rebut it only on one of the four grounds § 47a-20a makes exclusive — the Appellate Court has held that a landlord who proves none of the four has not rebutted the presumption. — Connecticut's protection is a shield rather than a sword.
Can a lease make the tenant responsible for repairs in Connecticut?
A delegation provision reaches beyond the usual single-family limits. Section 47a-4(a)(1) is the anti-waiver rule and it is chapter-wide: a rental agreement may not provide that the tenant agrees to waive or forfeit rights or remedies under this chapter and a long list of related sections, or under any general statute or municipal ordinance, unless that section or ordinance expressly says the rights may be waived. Section 47a-4(a)(3) separately voids any exculpation or limitation of the landlord's liability and any tenant indemnity for it, and a prohibited provision included in a rental agreement is unenforceable.
