Things landlords cannot do in Connecticut

Connecticut imposes steep penalties for landlord self-help. A lockout is a class C misdemeanor. A wrongly withheld security deposit costs the landlord double, while a single Section 8 refusal produced $7,500 in damages plus a $5,000 civil penalty before the Connecticut Appellate Court in 2022. Connecticut lawmakers amended the governing statutes repeatedly from 2023 through 2025, and two more acts take effect October 1, 2026. This guide identifies each prohibition and its governing statute. It also gives the attached penalty. Where relevant, it names the filing forum.

What a landlord cannot do in Connecticut: the short list

The prohibitions operate within the broader framework of Connecticut landlord-tenant laws. The table gives the operative rules for owners reviewing leases and tenants checking landlord conduct:

• Prohibited act | Statute | Penalty or remedy
• Locking out a tenant or shutting off utilities without a court order; removing belongings without a court order | C.G.S. § 47a-43; § 53a-214 | Court restores possession and property with costs (§ 47a-45a); discretionary double damages (§ 47a-46); class C misdemeanor
• Entering without reasonable notice or at unreasonable times; making harassing repeated demands for entry | C.G.S. § 47a-16 | Actual damages of at least one month's rent plus attorney's fees; injunction or lease termination (§ 47a-18a)
• Evicting or raising rent within six months of protected tenant activity; cutting services during that period | C.G.S. § 47a-20 | The law presumes retaliation. For an eviction, the landlord must prove one of four grounds in § 47a-20a(a); for a rent increase, the landlord must prove one of two justifications in § 47a-20a(b)
• Taking more than two months' deposit (one month at age 62 or older), skipping interest, or missing the return deadline | C.G.S. § 47a-21 | Twice the deposit; $10 or twice the unpaid interest when interest is the only violation; Banking Commissioner orders
• Charging a late fee before the grace period ends or above the statutory cap | C.G.S. § 47a-15a; § 47a-4 | Lease clause unenforceable
• Requiring electronic funds transfer as the only way to pay rent | C.G.S. § 47a-4c | Prohibited for leases executed on or after October 1, 2013
• Refusing a tenant because of Section 8 or another lawful source of income | C.G.S. § 46a-64c | CHRO complaint; damages and civil penalties ($7,500 plus $5,000 in CHRO ex rel. Cortes v. Valentin)
• Using revenue management software to set rents or occupancy | P.A. 25-1, § 32 | Connecticut Antitrust Act violation; Attorney General enforcement and civil penalty
• Charging application fees, move-in or move-out fees, or screening fees above $50 (CPI-adjusted) | C.G.S. § 47a-4d | Cap is statutory; the section names no dedicated penalty

Fair rent commissions in 52 municipalities add a local layer on rent increases that no row in the state table covers.

Illegal evictions: no lockouts, utility shutoffs or removing belongings

C.G.S. § 47a-43(a) bars four kinds of self-help: forcible entry into a dwelling unit and detaining it "with a strong hand," holding the unit by force after a peaceable entry without consent, entering and causing damage to the premises or damage to, removal of, or detention of the tenant's personal property, and putting a tenant in a position where they would have to damage the premises or breach the peace to get back in. Changing the locks and hauling furniture to the curb fit inside those categories. Pulling the front door off its hinges does too.

Utility shutoffs count too. The State's Attorneys' police training manual states that a tenant "can illegally be forced to vacate by means other than denying access, such as shutting off utilities to force the tenant to leave or by otherwise making the unit unusable."

The same manual answers the belongings question directly: a landlord who removes a tenant's possessions without changing the locks has committed "both a criminal and civil lockout under General Statutes § 53a-214 and General Statutes § 47a-43."

The Judicial Branch advises tenants that no shortcut exists: "The only legal way a landlord can remove a tenant from the property is through a court eviction action called summary process." A lease clause purporting to let you dispossess a tenant "without resort to court order" is void under § 47a-4. The guide to tenant eviction rights in Connecticut covers the court process, including the notice-to-quit stage and what happens at the hearing.

The remedies come from separate statutes:

• Statute | Remedy
• § 47a-45a | Once a court finds a violation, the judge "shall render judgment that the complainant be restored to, and reseized of, the premises" or that removed property be returned, with a writ of restitution and costs. That relief is mandatory.
• § 47a-46 | The tenant "may recover in a civil action double damages and his costs." The Connecticut Appellate Court has confirmed the doubling is discretionary, and the Connecticut Supreme Court held the standard of proof is the ordinary tort standard.
• § 53a-214 | A landlord, owner, or agent who deprives a tenant of access to the unit or their possessions "without benefit of a court order" is guilty of criminal lockout, a class C misdemeanor.

Attorney's fees do not come automatically. In Czaplicki v. Ogren, the Appellate Court refused to read fee-shifting into §§ 47a-45a and 47a-46 because neither contains express language authorizing it. Tenants have recovered fees on lockout facts through CUTPA instead, as in Freeman v. Alamo Management Co.

Notice to quit and summary process: the only lawful eviction route

Summary process in the Superior Court Housing Session is the only lawful way to recover possession of your property. Every step below replaces self-help. Neither a lockout nor a utility shutoff can substitute for it. A lease clause cannot either.

The process follows a strict sequence:

1. Serve a notice to quit. Before you file anything in court, a state marshal or other proper officer must serve the tenant with a notice to quit possession. The notice must identify the ground for termination.
2. Wait out the grace period for nonpayment. You cannot terminate for unpaid rent until nine days after rent is due, or four days for a one-week tenancy. Since January 1, 2026, that period extends an additional five days if your own online payment system blocked the tenant's payment.
3. Terminate the tenancy under §§ 47a-23 to 47a-23b. Once the notice period runs, termination follows under those statutes.
4. File the summary process complaint. File at the Housing Session for the town where the property is located.
5. Expect defenses at the hearing. A tenant may raise the § 47a-20 retaliation presumption if your case begins within six months of a protected complaint, the § 47a-23c just-cause limits if the tenant is 62 or older or has a disability and lives in a building of five or more units, and § 47a-4a's bar on collecting rent for any period the unit violated § 47a-7(a).

Finally, remember that a lease clause letting you dispossess a tenant "without resort to court order" is void under § 47a-4. The only permitted waiver of a notice to quit is the narrow, expressly worded lapse-of-time waiver under § 47a-25.

Entering without notice: landlord entry limits under C.G.S. 47a-16

If you enter an occupied unit as a Connecticut landlord, you must give the tenant "reasonable written or oral notice" and may enter "only at reasonable times, except in case of emergency." That language comes from § 47a-16(c), which also states that a landlord "shall not abuse the right of entry or use such right of entry to harass the tenant."

The statute defines none of its key terms numerically. No Connecticut statute sets a 24-hour notice period or a clock-hour window for "reasonable times." It also sets no count of demands that becomes harassment.

Courts apply an effect-based test. In Shaner v. Chick, one noticed entry to show the premises over more than two years was not harassment. In Rodriguez v. Ancona, a landlord who entered "without any prior notice" and claimed no emergency violated § 47a-16.

Section 47a-16(d) lists the only situations where entry without consent is lawful: an emergency, the extended-absence provision in § 47a-16a, a court order, or a tenant who has abandoned or surrendered the premises. In Haslam-James v. Lawrence, the Appellate Court found no violation where the landlord reasonably relied on representations that the tenant had abandoned the unit.

The penalty under § 47a-18a is the one number in this area. If a landlord subjects you to a prohibited entry, or to "repeated demands for entry otherwise lawful but which have the effect of unreasonably harassing the tenant," you may recover actual damages "not less than an amount equal to one month's rent and reasonable attorney's fees," plus an injunction or lease termination.

Rodriguez v. Ancona held that "one month's rent" includes the subsidized portion of a voucher tenant's rent, so the floor on a $1,800 unit is $1,800 even if the tenant pays $400. Resurreccion v. Normandy Heights adds that the tenant must prove the fee amount with an evidentiary showing.

The right runs both ways. Under § 47a-18, a tenant who refuses lawful entry exposes themselves to a declaratory judgment or injunction compelling access, lease termination, and the landlord's actual damages and attorney's fees.

Security deposits: what a landlord cannot charge, keep or delay

Under § 47a-21(b), a landlord cannot collect more than two months' rent as a security deposit from a tenant under 62, or more than one month's rent from a tenant 62 or older. A tenant who turns 62 mid-tenancy is entitled, on request, to a refund of any amount above one month's rent.

The deposit cannot sit in an operating account. The Department of Banking requires the landlord to hold it in escrow at a Connecticut financial institution, and § 47a-21(i) requires the landlord to pay interest at the deposit index the Banking Commissioner sets each year. For calendar year 2026 that rate is 0.49%. A lease clause waiving deposit interest is unenforceable under § 47a-4.

Public Act 23-207 tightened the return deadlines in 2023. It cut the old 30-day window to 21 days after the tenancy ends, and the landlord has until the later of that date or 15 days after receiving the tenant's written forwarding address.

Within that window the landlord must deliver the full deposit plus interest, or the balance with an itemized statement of damages.

Section 47a-21(d)(2) sets the penalty: a landlord who violates the subsection "shall be liable for twice the amount of any security deposit paid." If the only failure is unpaid interest, liability is $10 or twice the accrued interest, whichever is greater. The Judicial Branch's small claims guidance notes that a court may award twice the deposit even when the total exceeds the $5,000 small claims ceiling.

The Banking Commissioner also polices deposits. Under § 47a-21(j), the Commissioner may investigate complaints about the cap, the return deadline, the escrow requirement, and interest, and may issue cease-and-desist and compliance orders. Public Act 26-79 adds authority to order a civil penalty starting October 1, 2026.

The Commissioner has no jurisdiction over two things: a landlord's failure to pay interest annually, and a refusal to return a deposit based on a good-faith damage claim, even if the amount is disputed. Those disputes go to court.

Rent: late fees before the grace period, electronic-only payment and mid-lease increases

A Connecticut landlord cannot charge a late fee or begin termination until nine days after rent is due, or four days for a one-week tenancy. Since January 1, 2026, that grace period stretches five more days if the landlord's own online payment system prevented the tenant from paying on time (Nov. Sp. Sess. P.A. 25-1, § 38).

Section 47a-15a(b) caps late charges at the lesser of $5 per day up to $50, or 5% of the delinquent rent (the tenant's share, if a government program or charity pays part). A landlord may assess only one late charge per delinquent payment, no matter how long it stays unpaid. Section 47a-4 makes any lease clause demanding a late fee before the grace period ends, or above those caps, unenforceable.

Electronic-only rent is out. Under § 47a-4c, for any lease executed on or after October 1, 2013, "no landlord of residential real property shall require electronic funds transfer as the exclusive form of payment of rent or a security deposit." You may offer ACH or a portal; you cannot refuse a check.

On the amount, Connecticut has no statewide rent cap. Several rules constrain increases anyway:

• Rule | Constraint
• Public Act 24-143 | Effective October 1, 2024, it requires written notice of a proposed increase at least 45 days in advance, or notice equal to the lease term for leases of one month or less.
• Section 47a-20 | It bars any increase within six months of a tenant's code complaint, repair request, fair rent complaint, or tenant union membership, unless the landlord proves a tenant-caused condition or a substantial tax or operating cost increase that arose at least four months earlier.
• Section 47a-23c | For protected tenants who are age 62 or older, or disabled, in buildings of five or more units, rent may rise "only to the extent that such increase is fair and equitable" under the § 7-148c factors.

Discrimination a landlord cannot practice, including refusing Section 8 vouchers

Connecticut protects more classes than federal fair housing law, and the largest practical difference is source of income. C.G.S. § 46a-64c(a)(1) prohibits refusing to rent or negotiate "because of race, creed, color, national origin, ancestry, sex, gender identity or expression, marital status, age, lawful source of income, familial status, status as a veteran or status as a victim of domestic violence." Subsection (a)(2) separately bars discrimination in the terms, conditions, or privileges of a rental on the same grounds.

"Lawful source of income" under § 46a-63(3) includes Social Security, supplemental security income, housing assistance, child support, alimony, and public assistance. The Connecticut Supreme Court has held Section 8 vouchers fall within that definition.

In CHRO v. Sullivan Associates, 250 Conn. 763 (1999), the court wrote that "a landlord may not refuse to rent to a prospective low income tenant because that tenant will pay the stipulated rent from a lawful source of income, such as rental assistance under section 8." Source of income is not a protected basis under the federal Fair Housing Act, so out-of-state operators entering Connecticut often miss this rule.

The insufficient-income exception in § 46a-64c(b) does not rescue a blanket policy. The Supreme Court read it to concern only "the potential tenant's own ability to meet his or her personal rent obligation for that part of the rental not covered by section 8 rental assistance payments." Courts interpreting the statute have held that a landlord may not apply stricter income requirements to voucher applicants than to others.

Two exemptions survive: an owner-occupied room in a single-family dwelling and an owner-occupied two-family unit.

CHRO adjudicators awarded the following damages and penalties:

• In CHRO ex rel. Cortes v. Valentin, 213 Conn. App. 635 (2022), telling an applicant the property "was not section 8 ready" conveyed a preference for non-voucher tenants. The award was $7,500 in noneconomic damages and a $5,000 civil penalty.
• In Banks and Hansberry v. Eddie Eckhaus and Longhill Real Estate, a landlord who said "she does not rent to section 8 recipients" paid $4,500 in emotional distress damages to one complainant and $2,500 plus $862.94 in storage and $931 in rental costs to the other.
• In Pinto v. Englehard (CHRO No. 0550113, 2007), a landlord who withdrew after signing Section 8 paperwork lost; concerns about program reporting requirements "do not constitute a lawful reason to reject a section 8 applicant."

Connecticut added domestic violence victim status to the list on October 1, 2022, through P.A. 22-82. Section 47a-9a also restricts discrimination based on specified past cannabis-possession convictions.

Complaints go to the Commission on Human Rights and Opportunities. Under § 46a-82(f)(2), for acts on or after October 1, 2021, the deadline is 300 days from the discriminatory act. The CHRO's housing complaint webpage and brochure still display the older 180-day figure; the statute controls.

CHRO does not require notarization of a housing complaint, but contacting CHRO or filling out its online inquiry form does not count as filing. Once the complainant files, the respondent must answer under oath within 10 days or risk default. CHRO then requires mediation.

After a reasonable-cause finding, either side has 20 days to elect a Superior Court action instead of a public hearing. A tenant may also sue directly under § 46a-98a within one year of the act.

Retaliation: what a landlord cannot do after you complain

For six months after any of five tenant actions, § 47a-20 prohibits a landlord from maintaining an eviction, demanding a rent increase, or decreasing services. The five triggers are a good-faith effort to remedy a housing code violation (including a fair rent commission complaint), a municipal agency's notice or order about such a violation, a good-faith repair request to the landlord, a tenant's action under § 47a-14h, and organizing or joining a tenants' union.

The repair-request trigger is narrower than it sounds. Visco v. Cody, 16 Conn. App. 444 (1988), limited it to repairs necessary to keep the premises fit and habitable, so a request to repaint a hallway does not start the clock.

Once the tenant shows a triggering act and adverse action within six months, courts presume retaliation, subject to rebuttal. The Department of Housing's fair rent commission toolkit notes the statute "does not require proof of retaliatory motive."

For an eviction, the landlord carries the burden, and § 47a-20a(a) lists the only four grounds that rebut the presumption:

1. The tenant is using the unit for an illegal purpose, violating the rental agreement, or not paying rent.
2. The landlord seeks possession in good faith for immediate use as their own abode.
3. The tenant, a household member, or the tenant's guest willfully caused the condition complained of.
4. The landlord gave notice to terminate a periodic tenancy before the tenant's complaint.

Appellate cases enforce that list strictly. In Correa v. Ward, 91 Conn. App. 142 (2005), and Holdmeyer v. Thomas, 167 Conn. App. 544 (2016), landlords who could not prove one of the four grounds lost. The annotations state a landlord must produce "substantial countervailing evidence" of a legitimate interest, so a vague reference to wanting the unit back fails.

For rent increases, § 47a-20a(b) allows only two justifications: a condition caused by the tenant's lack of due care, or a substantial increase in property taxes or operating costs (unrelated to fixing the complaint) that arose at least four months before the demand, with the increase capped at the prorated share of the net cost increase.

Timing matters for which side carries the burden. Under § 47a-20, courts presume retaliation when summary process begins within six months of a complaint. Outside that window, § 47a-33 makes retaliation an affirmative defense the tenant must prove by a preponderance of the evidence. Neither section has been amended since P.A. 83-510.

Habitability: essential services a landlord cannot neglect

Under § 47a-7, a landlord cannot let heating, plumbing, or sanitary facilities fall out of good working order, and must "supply running water and reasonable amounts of hot water at all times and reasonable heat," except where a tenant controls the installation or the utility connects directly to the unit. Compliance with health and safety codes is also one of the thirteen factors a fair rent commission weighs when a tenant challenges rent.

Failure has a rent consequence written into the lease law itself. Section 47a-4a provides that a rental agreement "shall not permit the receipt of rent for any period during which the landlord has failed to comply with subsection (a) of section 47a-7."

Section 47a-13 gives tenants the following self-help remedies once they give written or oral notice of a missing essential service:

• Remedy | What the tenant may do
• Procure and deduct | Procure the service and deduct the actual, reasonable cost from rent.
• Substitute housing | Move to substitute housing if the landlord has not restored service within 48 hours of the breach, with rent abating for the period of noncompliance and substitute housing costs recoverable up to the abated amount. If the same breach recurs within six months, the tenant may relocate immediately.
• Terminate and recover damages | Terminate the lease if the failure is willful, and recover the greater of two months' periodic rent or double actual damages.

Section 47a-13 lets a tenant recover attorney's fees in any action under that statute. A fair rent commission can also suspend rent and order the tenant to pay it into escrow while a unit violates health and safety laws.

Lease clauses that are void in Connecticut

Section 47a-4(a) lists ten things a Connecticut rental agreement cannot require a tenant to do, and § 47a-4(b) makes any such clause unenforceable rather than voiding the whole lease. The prohibited terms are:

1. Waiving or forfeiting rights under Chapter 830 or any other statute or ordinance, unless the statute expressly permits waiver.
2. Authorizing the landlord to confess judgment on any claim arising from the rental agreement.
3. Waiving landlord liability, limiting it, or indemnifying the landlord against it.
4. Waiving interest on the security deposit under § 47a-21.
5. Permitting the landlord to dispossess the tenant without a court order.
6. Consenting to distraint of property for rent.
7. Paying the landlord's attorney's fees above 15% of any money judgment.
8. Paying a late charge before the § 47a-15a grace period expires, or paying reduced rent for early payment.
9. Paying a late charge above the § 47a-15a caps (added by P.A. 23-207, effective October 1, 2023).
10. Paying a heat or utilities surcharge when heat or utilities are included in the rent.

Connecticut adds an eleventh on October 1, 2026. Public Act 26-113 prohibits residential rental agreements from requiring tenants to pay for utilities when no separate meter measures delivery exclusively to their unit.

One narrow waiver survives. A tenant may waive the notice to quit for lapse of time under § 47a-25, but only when the clause is sufficiently express, so a general waiver of "all notices" does not qualify.

These prohibitions attach to the "rental agreement," not to a signed document. A landlord renting on a handshake gets no exemption, and CTLawHelp notes a tenant needs neither a written lease nor a lawyer to bring a complaint before a fair rent commission.

New and lesser-known prohibitions: algorithmic rent pricing, screening fees, cannabis

Recent rules enacted since 2021 trip up landlords who learned the law earlier. If you're asking about the "new renters law" in Connecticut, you are usually asking about one of the rules below.

Algorithmic rent-setting is an antitrust violation

Since January 1, 2026, using a revenue management device to set rents or occupancy levels for residential units is an unlawful practice under the Connecticut Antitrust Act. Section 32 of Nov. Sp. Sess. P.A. 25-1, signed by Governor Lamont on November 26, 2025, enacted the ban, and P.A. 25-49 contains an identical prohibition. Baker McKenzie's January 2026 analysis notes Connecticut became the third state to prohibit this kind of algorithmic pricing.

The definition targets software that processes "nonpublic competitor data" on local or statewide rents or occupancy to advise a landlord whether to leave a unit vacant or how much rent to charge. Nonpublic competitor data includes actual rent amounts, occupancy levels, and lease dates, whether attributable to a named competitor or anonymized.

Two products fall outside the ban: reports that publish aggregated existing rental data without recommending future rates, and tools used to set rent or income limits under affordable housing program guidelines. The Attorney General investigates and brings actions; the retrieved legislative analyses do not state the dollar amount of the civil penalty or whether a private right of action exists.

Portfolio operators should read the enforcement history. Attorney General William Tong joined the Department of Justice's August 23, 2024 lawsuit against RealPage, and the January 7, 2025 amended complaint added six large landlords, three of which Tong said operate in Connecticut.

Greystar agreed to a proposed $7 million settlement in November 2025, and LivCor agreed to a proposed $7 million settlement in June 2026. Both agreements bar the companies from using software that relies on competitors' sensitive data to set rent.

Application and screening fees are capped

Since October 1, 2023, § 47a-4d has barred landlords from charging any fee to process, review, or accept a rental application, and from charging move-in or move-out fees. A landlord may collect only four charges before or at the start of a tenancy: the security deposit, first month's rent in advance, deposits for keys or special equipment, and a fee for a tenant screening report.

The screening fee cannot exceed $50 plus an annual CPI adjustment set by the Commissioner of Housing. A landlord may charge up to the CPI-adjusted statutory cap regardless of the report's actual cost. A landlord who charges it must give the applicant a copy of the report (or instructions for obtaining it from the vendor) and a copy of the vendor's receipt or invoice.

The statute does not require a landlord to accept a tenant-supplied reusable report, and it contains no penalty subsection of its own.

Cannabis rules limit lease bans and screening

Since July 1, 2022, under § 47a-9a, a landlord or property manager "may not prohibit the possession of cannabis or the consumption of cannabis," with one carve-out: you may still prohibit smoking cannabis and using electronic cannabis devices or vapor products. A lease may ban cannabis smoking and vaping. Unless a statutory exception applies, it must permit edible cannabis.

Two screening rules follow. A landlord may not refuse or otherwise discriminate against an applicant or tenant based on a past conviction for possession under § 21a-279a or for possession of four or fewer ounces of cannabis plant material, and "may not require a tenant to submit to a drug test." Under § 21a-408p(b)(2), a landlord also may not refuse to rent or take action against a tenant "solely" because of their status as a qualifying medical cannabis patient or caregiver.

The statutory exceptions cover roomers who lease less than the whole residence, housing incidental to detention or medical, educational, or religious services, sober living or transitional housing, and situations where compliance would violate federal law or cost the landlord a federal monetary or licensing benefit.

That last exception matters for HUD-assisted units, where HUD has stated it lacks discretion to admit marijuana users, including medical users. State law allows adults to grow up to three mature and three immature plants each, 12 per household, indoors at their primary residence; § 47a-9a is silent on whether a lease may ban cultivation.

Special protections: seniors, domestic violence survivors and winter heat

Tenants age 62 and older benefit from the one-month deposit cap. Several groups of Connecticut tenants also carry protections a landlord cannot contract around.

Tenants 62 and older, and tenants with disabilities

In buildings or complexes of five or more units, § 47a-23c allows eviction of a protected tenant only for listed causes:

• Permitted cause | Limitation
• Nonpayment | The landlord may seek eviction for nonpayment of rent.
• Refusal of a fair and equitable rent increase | The landlord cannot use this ground during an existing lease term.
• Material noncompliance | This includes material noncompliance with the lease or with health-and-safety duties.
• Permanent removal from the market | The landlord cannot use this ground during an existing lease term.
• Landlord occupancy | The landlord must have a bona fide intent to use the unit as a principal residence and cannot use this ground during an existing lease term.

Protected status covers tenants 62 or older, tenants whose spouse, sibling, parent, or grandparent aged 62 or older lives with them, and tenants or their household members, including children, with a disability expected to last at least 12 months.

A landlord may demand proof. If you claim protected status, you have 30 days to provide it.

Since January 1, 2024, P.A. 23-207 has required landlords of five-plus-unit buildings to hand tenants a one-page plain-language summary of these protections, in English and Spanish, at signing, renewal, or initial rental.

Domestic violence and sexual assault survivors

Under § 47a-11e, a tenant who is a victim of family violence (leases on or after January 1, 2011) or sexual assault (leases on or after January 1, 2014) may terminate the lease on 30 days' written notice with a sworn statement. The tenant must attach either a police or court record dated within 90 days of the notice, or a signed statement from an employee of the Office of Victim Services or the Office of Victim Advocate dated within 30 days.

Stalking is not a listed category, and the statute does not accept protective orders or health professional statements as documentation. The departing tenant remains liable for prior arrears and any damage they caused, and co-tenants remain bound.

Lock changes have their own clock under § 47a-7b. A tenant may request new locks by providing a protective or restraining order that names the tenant and requires the respondent to stay away from the home.

The landlord must respond within six hours, change the locks within 48 hours if agreeing to do it, and may charge only the actual cost of the lock and locksmith. If the landlord fails to act, the tenant may change the locks and must deliver a key within two business days. The landlord may deduct an unpaid lock-change bill from the deposit or sue to collect it, but the bill "shall not be the basis for a summary process action."

Winter heat and utilities

A landlord's shutoff of heat, water, or power to pressure a tenant is a criminal lockout under § 53a-214 in any season.

The winter-specific protections apply to utility companies. Under §§ 16-262c and 16-262d, from November 1 to May 1 no electric or gas provider may terminate residential service to a hardship customer who lacks the resources to pay the full account. A provider also cannot cut service at any time of year where termination would create a life-threatening situation or where a child under 24 months in the household has a physician's certification of medical necessity.

Utilities must mail notice at least 13 calendar days before any termination. They may not shut off service on Fridays, weekends, holidays, or the day before a holiday.

When a landlord stops paying a building-wide utility bill, § 16-262e requires the utility to notify occupants before terminating and to offer them service in their own names without liability for the landlord's debt and without a security deposit. The statute treats any amount a tenant pays the utility under this section as rent, and the tenant may deduct it from what they owe the landlord. The landlord may not raise rent to recoup those deductions.

Fair Rent Commissions: the municipal layer on rent increases

Connecticut sets no rent cap, but 52 municipalities had fair rent commission ordinances as of the Department of Housing's August 15, 2024 count, and a commission can roll back an increase it finds "so excessive, with due regard to all the circumstances, as to be harsh and unconscionable."

State law requires a commission in every municipality of 25,000 or more; Nov. Sp. Sess. P.A. 25-1 lowered that threshold to 15,000 as of January 1, 2026, with a compliance deadline of January 1, 2028. Towns may meet the mandate alone or through a joint or regional commission.

The Department of Housing count includes the following municipalities:

• Category | Municipalities
• Every large city | Hartford, New Haven, Stamford, Bridgeport, and Waterbury
• Mid-size cities | Norwalk, Danbury, New Britain, Manchester, Meriden, Middletown, New London, Norwich, and Torrington
• Suburbs | West Hartford, Hamden, Glastonbury, Fairfield, Greenwich, Milford, Stratford, Trumbull, Westport, and Wallingford
• Four towns below the old threshold that adopted ordinances voluntarily | Colchester, Clinton, Westbrook, and Killingworth

Seasonal rentals of 120 days or fewer per year sit outside commission jurisdiction.

Section 7-148c gives commissions 13 factors to weigh. They include rents for comparable units, sanitary conditions, necessary repairs, and the landlord's taxes and debt service. Commissions also consider compliance with health and safety codes, the tenant's income, the amount and frequency of past increases, and whether the new income will fund improvements.

Under § 7-148d, the commission may limit rent to an amount it finds fair, phase an increase in, delay it pending repairs, or suspend rent entirely and order tenants to pay it into escrow while the unit violates health and safety laws.

A landlord who violates a rent reduction or suspension order faces a fine of $25 to $100 per offense under § 7-148f, and after five days each day counts as a new offense. Either party may appeal to the Superior Court within 30 days.

Filing follows a common statutory pattern with local variations:

• Any tenant in a town with a commission may file, with no written lease or lawyer required.
• Grounds include an increase that seems too high, a landlord newly charging for utilities that were included in rent, code violations, or a rent increase or eviction filed after a housing complaint.
• The tenant owes only the pre-increase rent until the commission decides.
• The commission must schedule the hearing within 30 days of filing unless doing so is impracticable, with 10 days' notice by first-class and certified mail. Since July 1, 2025, commissions must open all hearings to the public (P.A. 25-121).
• The commission must issue its decision at the hearing or within 30 days afterward, and a rollback can take effect from the month the complaint was filed.

Hartford sends a housing code inspector out before mediation and hearing. New Haven runs a four-step process with hearings within 60 days (30 for retaliation claims) and decisions within 10 days. Stamford routes complaints through its Social Services Commission. Bridgeport requires rent to be current before filing and takes complaints at FairRentCommission@BridgeportCT.gov or 203-576-8323.

Filing a fair rent complaint in good faith also triggers the six-month retaliation shield under § 47a-20, and the commission itself may order a landlord to cease and desist from retaliatory conduct.

If your landlord broke the law: where to file and what you can recover

Each violation has a different forum, and filing in the wrong one wastes weeks. For landlords, the same map shows where a complaint against you will land:

• Violation | Where to file | What the tenant can recover
• Lockout, utility shutoff, removed belongings | Housing Session of the Superior Court for the property's location (Bridgeport, Hartford, New Britain, New Haven, Stamford/Norwalk, Waterbury) | Restoration of possession, return of property, costs, discretionary double damages; class C misdemeanor charges through police
• Entry without notice or harassing entry demands | Housing Session or Superior Court | Actual damages of at least one month's rent, attorney's fees, injunction
• Deposit not returned, over cap, no interest | Small Claims (twice the deposit, even above $5,000); Department of Banking, Government Relations & Consumer Affairs, 280 Trumbull Street, 16th floor, Hartford, CT 06103 | Twice the deposit; $10 or twice the interest; Banking Commissioner orders and, from October 1, 2026, civil penalties
• Source-of-income or other discrimination | Commission on Human Rights and Opportunities, within 300 days | Damages and civil penalties; or a Superior Court action within one year under § 46a-98a
• Excessive rent increase | Municipal fair rent commission, where one exists | Rollback, phase-in, or suspension order
• Habitability failure | Housing Session (tenant application to enforce housing rights under § 47a-14h, $25 fee); fair rent commission escrow order | Rent abatement, repair-and-deduct, termination damages under § 47a-13, attorney's fees
• Retaliatory eviction or increase | Raised as a defense in the eviction case; fair rent commission for increases | Eviction dismissed unless landlord proves a § 47a-20a ground

Statewide Legal Services runs a hotline at 1-800-453-3320 with emergency hours from 2 pm to 4:45 pm Monday through Friday for tenants who cannot afford a lawyer. The details of what tenants have the right to demand in each of these forums are covered separately.

The first 48 hours after a lockout or utility shutoff

CTLawHelp's October 2025 eviction guide gives a two-word instruction: "Call the police right away. A lockout is a crime." The steps that follow move fastest in this order:

1. Call the police and bring proof you live there: a rent receipt, cancelled check, or utility bill in your name. CTLawHelp states you "have the right to ask the police to order your landlord to let you back into your apartment," and to ask for the landlord's arrest if they refuse.
2. Go to the Housing Session clerk for the court district where the property sits. Complete form JD-HM-024, the Verified Lockout Complaint and Application for Temporary Injunction (Rev. 04/26). You must sign and verify it under oath before a clerk, notary, or attorney.
3. Ask the clerk for JD-HM-037, the Ex-Parte Temporary Injunction, which is available only at clerk's offices. If a judge grants it, the judge may order the landlord to immediately give you possession of the premises before the hearing.
4. Pay the $175 entry fee or file JD-CV-120 to request a fee waiver; a single waiver application covers both the filing fee and the State Marshal's service fee.
5. The clerk completes the summons (JD-HM-023) and order to show cause. A marshal must serve the landlord at least six days before the hearing, and § 47a-43(b) requires the hearing within eight days of the complaint.
6. At the hearing, the judge may send the case to mediation first. If mediation fails, both sides present evidence. If the judge finds for the tenant, § 47a-45a requires the judge to restore possession.

Photograph the physical evidence before anything moves. That may include a changed lock or dark meter. Also capture any belongings on the curb. The court has discretion to award double damages after finding a § 47a-43 violation.

For landlords, the legal exposure is the compliance half of protecting a Connecticut rental. The other half covers property damage from fire or storms.

FAQ

These answers summarize common Connecticut questions about deadlines and remedies. They also identify the filing routes landlords and tenants ask about most often.

What is the new renters law in Connecticut?

Several laws share that label. Public Act 23-207 (October 1, 2023) capped late fees and banned application and move-in fees. It also capped screening fees at $50, cut the deposit return deadline to 21 days, and extended just-cause protections to disabled tenants in five-plus-unit buildings. Public Act 24-143 (October 1, 2024) requires 45 days' written notice of rent increases. Nov. Sp. Sess. P.A. 25-1 (January 1, 2026) banned algorithmic rent-setting and added a five-day grace extension when a landlord's payment portal fails. It also lowered the fair rent commission threshold to 15,000 residents.

What rights do tenants have in Connecticut?

Tenants can stay until a court orders otherwise, receive reasonable notice before entry, get their deposit with interest within 21 days, pay rent by check, and be free from retaliation for six months after a code complaint or repair request. In towns with fair rent commissions they can challenge an excessive increase, and in five-plus-unit buildings tenants 62 and older or with disabilities can only be evicted for the causes listed in § 47a-23c.

When can a landlord evict a tenant in Connecticut?

The only lawful route is summary process in the Superior Court Housing Session for the town where the property is located. Before filing a summary process complaint, the landlord must first serve the tenant with a notice to quit possession, delivered by a state marshal or other proper officer, that identifies the specific ground for termination.

For nonpayment, the ground ripens only after the § 47a-15a grace period runs: nine days after rent is due, or four days for a one-week tenancy. Since January 1, 2026, the landlord must allow an additional five days if the landlord's own online payment system prevented the tenant from paying. Within six months of a tenant's protected complaint, the landlord must also prove one of the four § 47a-20a grounds: illegal use or lease violation, the landlord's own occupancy, a tenant-caused condition, or a termination notice that predates the complaint.

How much notice does a landlord have to give before entering in Connecticut?

Section 47a-16 requires "reasonable written or oral notice" and entry at "reasonable times," with no number of hours defined in statute. Emergencies, court orders, and abandoned units are the exceptions. A violation costs at least one month's rent plus attorney's fees under § 47a-18a.

Can a landlord raise rent mid-lease in Connecticut?

Connecticut requires at least 45 days' written notice of a proposed increase, or notice equal to the lease term for leases of one month or less. A landlord cannot raise rent within six months of a protected tenant complaint unless the landlord proves one of the two justifications in § 47a-20a(b). In fair rent commission towns, the commission can review an increase for harsh and unconscionable excess. Connecticut has no statewide cap on the amount.

Can a tenant withhold rent or pay into escrow for unmade repairs in Connecticut?

Stopping payment without a court or commission order invites a nonpayment eviction. The lawful routes are an application to enforce housing rights under § 47a-14h (a $25 filing fee), the § 47a-13 remedies for missing essential services (procure and deduct, substitute housing after 48 hours, or termination for willful failure), and a fair rent commission complaint, which can result in an order suspending rent and holding it in escrow until the unit complies with health and safety codes. Section 47a-4a also bars a landlord from collecting rent for any period of noncompliance with § 47a-7(a).
