Does Connecticut Have Rent Control Laws?
Connecticut does not have statewide rent control laws limiting the amount that landlords may ask for rent. State law prohibits local governments from establishing rent control laws except to establish a fair rent commission that handles complaints and prevents landlords from charging excessive rents.
Since 2022, Connecticut requires all cities with a population over 25,000 to establish a fair rent commission.
When Can a Landlord Raise Rent in Connecticut?
Landlords in Connecticut can raise the rent at any time, as long as they comply with the following:
- Wait until the end of the lease term (unless otherwise specified in the lease)
- Give reasonable notice
- Aren’t raising rent for discriminatory or retaliatory reasons
45 days before the end of a year-long lease, a landlord sends a notice that rent will increase by 5% if they choose to renew the lease.
When Can’t a Landlord Raise Rent in Connecticut?
Landlords in Connecticut may not raise the rent if:
- The increase is applied in a way that discriminates against one of the protected classes specified in the Fair Housing Act
- It is during the middle of a lease’s fixed term (unless stated otherwise in the lease agreement
- It is done as retaliation against a protected tenant action, such as filing a complaint
State law also prohibits discrimination based on a past conviction for possession of cannabis products, or 4 or fewer ounces of cannabis plant material. An unfair rent increase could count as discrimination under this law.
How Often Can Rent Be Increased in Connecticut?
Landlords in Connecticut can increase the rent as often as they wish, as long as sufficient notice is provided each time.
How Much Notice Is Needed to Raise Rent in Connecticut?
Connecticut law requires 45 days of notice before a rent increase, for most leases. For month-to-month and shorter leases, the notice period is instead the term of the lease: one month for a month-to-month lease, one week for a week-to-week lease, and so on.
How Much Can a Landlord Raise Rent in Connecticut?
In areas with a fair rent commission, landlords in Connecticut cannot raise the rent by an amount that would be considered “harsh and unconscionable.”
If a tenant thinks a rent increase is unreasonable, they must submit a complaint to their local Fair Housing Commission to contest it.
Fair rent commissions are required to consider these factors:
- Amount and frequency of rent increases
- Landlord’s operating costs
- Number and size of bedrooms
- Repairs necessary to make the accommodations livable
- Number of bathtubs, showers, toilets, and sinks
- Services, furniture, and furnishings
- Availability of utilities
- Comparable rents
- Sanitary conditions
- Compliance with state and local health and safety laws and regulations
- Renter’s income and housing availability
- Tenant damage to the premises, other than ordinary wear and tear
- Potential reinvestment in the property
After a tenant files a complaint, the commission will hold a hearing and may:
- Order a reduction of the rent increase
- Order the rent increase to be phased over time
- Deny the rent increase
- Require the rent increase to be delayed until the landlord complies with health and safety requirements or makes necessary repairs
- Deny the tenant’s claim
Tenants can file a case with Superior Court to contest a rent increase if their local government does not have a fair rent commission and they live in a mobile home or a building or complex with 5 or more dwellings and are disabled or 62 years old or older.
In boroughs and towns without a fair rent commission, landlords can raise the rent by any amount they wish. There is no legal limit or cap on the amount of a rent increase in those areas.

As of April 2025, the Connecticut state government has not yet updated its statutes to reflect a 2024 change establishing a 45-day requirement. The new statute likely will be designated Conn. Gen. Stat. § 47a-47 upon update:
=====
Sec. 17. (NEW) (Effective October 1, 2024, and applicable to rental agreements entered into, renewed or extended on or after October 1, 2024) No rent increase for a dwelling unit shall be effective unless the landlord has given the tenant of such dwelling unit written notice of the proposed increase not less than forty-five days before the day on which the increase is proposed to take effect, except in the case of a lease with a term of one month or less, such notice shall be given a number of days equivalent to the length of a full term of such lease. A tenant’s failure to respond to such notice shall not constitute the tenant’s agreement to such proposed increase. Nothing in this section shall be construed to (1) allow a landlord to increase the rent during the term of a rental agreement, or (2) alter any notice requirements concerning increases in rent imposed by federal law.

Except as provided in this section, a landlord or property manager may not refuse to rent to a prospective tenant or an existing tenant, or otherwise discriminate against a prospective tenant or an existing tenant, based on a past conviction for possession of a cannabis-type substance under section 21a-279a of the general statutes, or for a past conviction for possession of four or fewer ounces of cannabis plant material, and any equivalencies and combinations thereof, pursuant to subsection (i) of section 21a-279a of the general statutes in any other jurisdiction.

(a) If a commission determines, after a hearing, that the rental charge or proposed increase in the rental charge for any housing accommodation is so excessive, based on the standards and criteria set forth in section 7-148c, as to be harsh and unconscionable, it may order that the rent be limited to such an amount as it determines to be fair and equitable. If a commission determines, after a hearing, that the housing accommodation in question fails to comply with any municipal ordinance or state statute or regulation relating to health and safety, it may order the suspension of further payment of rent by the tenant until such time as the landlord makes the necessary changes, repairs or installations so as to bring such housing accommodation into compliance with such ordinance, statute or regulation. The rent during said period shall be paid to the commission to be held in escrow subject to ordinances or provisions adopted by the town, city or borough.
(b) If the commission determines, after a hearing, that a landlord has retaliated in any manner against a tenant because the tenant has complained to the commission, the commission may order the landlord to cease and desist from such conduct.
