Hartford, CT — landlord and rental rules

Hartford's Fair Rent Commission accepts tenant complaints about allegedly excessive rent increases and other qualifying rental charges and may issue binding relief after investigation and hearing. It does not publish a blanket numeric rent cap.

Confirm filing eligibility and current Commission procedure for the particular tenancy.

Connecticut restricts possession actions, rent increases, and service reductions during the six months after specified good-faith tenant activity. A landlord may remove a residential tenant only through the court summary-process procedure, subject to the statutory grounds, notices, defenses, and exceptions.

The retaliation statute has express exceptions, and eviction timing cannot be reduced to a guaranteed number of days. Review the live facts and obtain legal advice before serving notice.

Hartford requires a separate active rental license for each covered residential rental building; issuance depends on a complete application, required documents and fees, and successful City inspections. The current final phase requires non-owner-occupied three-unit buildings to submit from July 1 through October 31, 2026; the building-wide license lasts four years and replaces the Certificate of Apartment Occupancy requirement for units in the licensed building.

The City identifies limited exemptions, including an owner-occupied three-unit building.

The current final phase covers non-owner-occupied three-unit buildings; the 40-plus, 10-to-39, and 4-to-9-unit submission windows ended in 2023, 2024, and 2025 respectively, but an owner who missed the applicable window still owes the application and the City's published additional late fee. The application fee includes the initial Housing Code and Fire Marshal inspections, and the Fire Marshal conducts required annual inspections during the four-year license. Hotels, motels, rooming houses, and group living have separate published 2023 fees. Confirm exemptions and the issued license record.

A landlord must comply with health-and-safety housing codes, keep the premises fit and habitable, maintain common areas and supplied systems, arrange waste removal, and provide the water, hot water, and heat required by the statute.

The exact heat and hot-water duties depend on the building and utility arrangement described in section 47a-7. Local codes may add requirements.

Connecticut advises landlords of pre-1978 housing to keep painted surfaces intact and follow state and federal lead-safe work rules. When a qualifying investigation identifies lead hazards, the local health department may order an approved abatement plan and clearance before reoccupancy.

A child under six with an elevated venous blood-lead level triggers the official investigation path described by DPH. Do not infer that every pre-1978 property has been inspected or certified lead-safe.

Connecticut generally caps a security deposit at two months' rent for a tenant under 62 and one month's rent for a tenant 62 or older. The landlord must use the statutory escrow arrangement, pay required interest, and ordinarily return the deposit and itemization no later than 21 days after termination or 15 days after receiving the written forwarding address, whichever is later.

The statute contains account, notice, interest, withholding, successor, and damages rules. The one-month senior limit includes a right to request return of an excess deposit after turning 62.

Damages

2× the deposit, plus fees

Senior deposit ceiling

One month's rent at age 62 or older

Return deadline

21 days after termination or 15 days after written forwarding address, whichever is later

A landlord may not charge for processing, reviewing, or accepting a rental application, or charge move-in or move-out fees. A tenant-screening-report fee may be charged only within the statute's annually adjusted ceiling.

The statute separately permits the security deposit, first month's rent, a key or special-equipment deposit, and a compliant tenant-screening-report fee. Verify the Department of Housing's current annual adjustment before charging.

Statutory base screening fee

$50, adjusted annually for CPI-U increases from October 1, 2023

Connecticut requires municipalities above the statutory population threshold to create a fair-rent commission and allows smaller municipalities to create one alone or jointly. A commission may investigate and act on harsh and unconscionable rental charges under the enabling statutes and adopted ordinance.

Do not infer adoption from population. Listingprobe attaches a municipal commission only when an official state or city source identifies the adopted local body.

Mandatory population threshold

25,000 under the most recent decennial census
