Connecticut Rent Increase Notice Requirements

Connecticut does not cap rent or impose a statewide statutory notice period for raising rent. For a month-to-month tenancy, a rent change takes effect for the next monthly term, so landlords generally give at least one month's notice; a tenant who rejects the new rent may instead receive a notice to quit. Public Act 22-30 and Conn. Gen. Stat. Sec. 7-148b require every municipality with population over 25,000 to maintain a fair rent commission. Under Sec. 7-148c, a commission may investigate and prohibit rents it finds 'so excessive...as to be harsh and unconscionable,' considering factors like the property's condition and operating costs.

No statutory penalty for the increase itself; a tenant may petition the town's fair rent commission, which can order an unconscionable rent reduced or frozen pending repairs.
