Connecticut Residential Lease Agreement

Last Updated: May 14, 2025 by Roberto Valenzuela

A Connecticut residential lease agreement (“rental agreement”) is a legal contract between a landlord overseeing a rental property and a tenant using the property. State and local laws set the rules for rental agreements, such as laws regulating the use of a tenant’s security deposit.

Connecticut Residential Lease Agreement Disclosures

Connecticut requires the following disclosures for some or all residential lease agreements.

Disclosure Applicable To
Landlord’s Name and Address All Units
Common Interest Units in a Common Interest Community
Fire Sprinkler System Units that Require a Fire Sprinkler System
Bed Bugs All Units
Move-In Checklist All Leases Beginning Jan. 1, 2024
Notice of Elderly and Disabled Tenant Rights All New Leases on Properties with 5+ Units
Lead Paint All Units Built Before 1978

Landlord’s Name and Address

Applies to all Connecticut rentals.

Connecticut landlords and tenants must have a way to communicate important notices and demands. In the lease, landlords must provide their name and address, or that of their authorized agent. Most leases in practice include additional contact information, such as phone numbers and email addresses. The tenant must receive this information when the lease begins, or earlier.

Common Interest Community Notice

Applies to all Connecticut rentals units located in a common interest community.

Connecticut leases must contain a disclosure if they are located in a common interest community (where the tenant pays fees for shared amenities).

This is an example of a common interest community disclosure:

NOTICE OF COMMON INTEREST COMMUNITY. This property is located in a common interest community, which means that the Tenant may be subjected to fees associated with the support of common interests such as amenities.

Operative Fire Sprinkler System Notice

Applies to all Connecticut rentals units that require a fire sprinkler system.

Connecticut requires some properties to have a fire sprinkler system. Landlords of these properties must disclose to tenants whether the sprinkler system is installed and in proper operating condition. If installed, the landlord must attach the maintenance and inspection history of the system to the lease. The notice must be written in 12-point, boldfaced and uniform font.

Bed Bug Disclosure

Applies to all Connecticut rentals.

Connecticut landlords must provide notice of infestation whenever bed bugs are found on the rental property or an adjacent or contiguous property. Upon a tenant’s request, the landlord also must disclose the last date of inspection for bed bugs.

This is an example of a bed bug disclosure clause:

BED BUGS. At the time of presenting this agreement, Landlord certifies:

[ ] No known current infestation or history of bed bugs in this property.
[ ] There is no known current infestation, but there is a history of infestation in this property.
[ ] No known current infestation, but there is a nearby infestation or history of infestations which may place the property at risk.

Move-In Checklist

Applies to all leases which begin on or later than January 1, 2024.

Connecticut landlords must provide a move-in checklist (alongside a signed copy of the lease) to inventory existing property damage. The landlord must walk the tenant through, with the checklist, before the tenant moves in. This ensures accurate deductions from the security deposit upon move-out.

A landlord cannot deduct from the security deposit to repair issues which already were noted on the move-in checklist.

Notice of Elderly and Disabled Tenant Rights

Applies to all leases in a complex or mobile home park with five or more dwellings, beginning January 1, 2024.

Connecticut law gives special protections to tenants over age 62, disabled tenants, and family members who live with them. Some types of evictions and rent increases aren’t allowed if a tenant falls into one of these protected categories. Landlords of properties which contain five or more units must provide a Housing Commission notice about these rights with every new or renewed tenancy.

Applies to any Connecticut rentals built before 1978.

Connecticut residential leases for property built before 1978 must, by federal law, contain a lead-based paint disclosure. This requires landlords to do the following:

Optional Disclosures and Addenda (Recommended)

The following lease agreement disclosures and addenda are not required by Connecticut law in residential lease agreements, but help with tenant management and landlord liability.

Optional Disclosure Purpose
Asbestos Informs tenants about any asbestos hazards related to the property. Tenants can reduce asbestos risk by not disturbing asbestos fibers.
Late/Returned Check Fees Specifies late fees or returned check fees related to the lease. Connecticut caps late fees at 5% of the late payment or $5/day up to maximum $50, whichever is less. Returned check fees are capped at $20 per check.
Medical Marijuana Use Informs tenants about policy related to medical marijuana use on the rental property. Some state laws allow landlords to restrict marijuana usage to non-smoking methods only, or allow use only in designated smoking areas.
Mold Disclosure Informs tenants about actual or suspected mold contamination on the property efforts, plus information about treatments. This helps limit landlord liability.
Non-Refundable Fees Charges not agreed by the tenant in the lease may be refundable when the lease ends. For Connecticut landlords to charge a non-refundable fee, it must be disclosed and agreed as such in the lease.
Shared Utilities Arrangements Sets terms for how to divide utility costs up on properties which share a utility meter with other units. This ensures tenants receive fair charges and understand what uses contribute to their bill.
Smoking Informs tenants of designated smoking areas that do not interfere with the quiet enjoyment of other tenants.

Consequences of Not Including Mandatory Disclosures

Mandatory disclosures outline important health, safety, and property information for the benefit of both landlord and tenant. A landlord who fails to provide federally or state-mandated disclosures could face legal consequences or monetary penalties, either from a tenant lawsuit or from state officials. Many lease provisions may be unenforceable without legally required disclosures.

Failure to comply with the state bed bug disclosure requirements carries liability for the tenant’s attorney fees, plus the greater of $250 or the tenant’s actual damages as a fine.

Failure to comply with the federal lead-based paint hazard disclosure risks fines of tens of thousands of dollars per violation.
