Notice before a rent increase · Connecticut

45 days, and a commission you can complain to

Dedicated statute

Connecticut requires 45 days notice of a rent increase under C.G.S. 47a-4e, a rule that took effect only on October 1, 2024, and every municipality of 25,000 or more must run a fair rent commission that can strike down excessive rents.

The notice periods in Connecticut

How much warning is required before a higher rent can take effect, and how a fixed lease is treated.

When	Notice in Connecticut	What it means
Rent increase (agreements from October 1, 2024)	45 days	At least 45 days notice under C.G.S. 47a-4e, applicable to rental agreements entered into, renewed, or extended on or after October 1, 2024.
Fair rent commission review	By complaint	Municipalities of 25,000 or more must run a fair rent commission that can rule an increase excessive and strike it down. Rental charge includes fees as well as rent.
Fixed-term lease	None mid-term	During a fixed-term lease the rent is fixed until renewal. The 45-day notice applies to agreements entered, renewed, or extended on or after October 1, 2024.
Limit on the amount	Separate rule	Connecticut has no statewide cap, but a fair rent commission may act on rents that are excessive, meaning harsh and unconscionable, so a limit on the amount exists through that route in covered municipalities.
Local ordinance	Varies	This is the whole Connecticut answer on amount. Under C.G.S. 7-148b, municipalities of 25,000 or more must adopt an ordinance creating a fair rent commission, which can investigate and eliminate excessive rental charges, including fees on top of rent. Confirm the current municipal list.
If notice is skipped	Not effective	A Connecticut renter has a calendar right and a substantive right. The 45-day notice is a recent statutory requirement, and the fair rent commission can rule an increase excessive. Separately, C.G.S. 47a-23c protects tenants 62 and older and tenants with disabilities in buildings of five or more units.

Recent or pending change

The 45-day notice took effect October 1, 2024, so most commercial guides still say Connecticut has no rent-increase notice statute and are out of date. Confirm the current fair rent commission municipal list and population threshold.

Next steps if your rent is going up

Concrete, neutral steps to check a rent increase in Connecticut. This is legal information, not legal advice.

Check whether the 45-day rule reaches your lease
C.G.S. 47a-4e applies to agreements entered, renewed, or extended on or after October 1, 2024. If your agreement is older and unrenewed, you may fall outside it, so that is the first question.
Find out if your town has a fair rent commission
Municipalities of 25,000 or more must run one. It can rule an increase excessive and strike it down, and rental charge includes fees, so it is a real route against a large increase.
Check senior and disability protections
C.G.S. 47a-23c gives added protection to tenants 62 and older and tenants with disabilities in buildings of five or more units. If that applies to you, get specific advice.
Get local help
A local Connecticut legal aid office or your town fair rent commission can act on an excessive increase. Search for legal aid in your area.

This is general legal information, not legal advice. Read your own lease and check for a local ordinance, since either can change the notice that applies to your home.

What Connecticut renters get wrong

Connecticut now does both things at once, and the notice half is so new that almost nothing published reflects it. Since October 1, 2024 a landlord owes 45 days notice of a rent increase under C.G.S. 47a-4e, which is longer than most of the country, and it applies to agreements entered, renewed, or extended on or after that date. On top of that, every municipality of 25,000 or more must run a fair rent commission under C.G.S. 7-148b, with power to rule an increase excessive and strike it down, and rental charge is defined to include fees as well as rent. So a Connecticut renter has a calendar right and a substantive right, and the page leads with the fact that the calendar right did not exist two years ago. Most commercial guides still say Connecticut has no rent-increase notice statute, and they are out of date. Tenants 62 and older and tenants with disabilities in buildings of five or more units get additional protection under C.G.S. 47a-23c. The first question for a renter is whether their agreement is recent enough to fall under the new 45-day rule.

Common questions

Is Connecticut rent-increase notice really 45 days now?

Yes, for covered agreements. C.G.S. 47a-4e requires 45 days notice of a rent increase, effective October 1, 2024. It is new enough that most guides still say Connecticut has no such statute, which is out of date.

Does the new rule apply to my lease, or only renewals after October 2024?

It applies to rental agreements entered into, renewed, or extended on or after October 1, 2024. A renter on an older unrenewed agreement may fall outside it, so check when your agreement was last entered or renewed.

Does my town have a fair rent commission in Connecticut?

If your municipality has 25,000 or more people by the most recent decennial census, it must run one under C.G.S. 7-148b. The commission can rule an increase excessive and eliminate it, so confirm whether your town has one.

Do added fees count as rent in Connecticut?

For fair rent commission purposes, yes. Rental charge is defined to include fees and charges in addition to rent, so a commission can look at an increase in fees as well as base rent when deciding whether a charge is excessive.
