How long can a residential lease be in Connecticut?

Depending on circumstances, in Connecticut it’s usually possible to have a lease of any length of time, as long as the length of the lease term is specific and agreed in writing by the landlord and tenant. Oral leases can almost never be for a term of more than one year.

Is a Contract to Lease Binding in Connecticut?

Yes, a contract to lease is legally binding in Connecticut. To be valid, a contract to lease may have to be written, especially for a fixed term over one year. Oral leases may be valid in some cases (especially when both parties later behave as though there’s an enforceable oral lease), but often have strict limitations on enforceability for things like length of the lease term.

Do Lease Agreements Need to Be Notarized in Connecticut?

No, lease agreements do not need to be notarized in Connecticut. A notary helps establish the identity of the people signing the lease, if there’s a claim of fraud, but a notary isn’t necessary for a lease to be valid.

Can a Lease Automatically Renew in Connecticut?

Yes, a lease can automatically renew in Connecticut. Most rental agreements will automatically renew when the initial tenancy period is over, if neither party takes action. Past this point, the lease typically becomes a month-to-month rental agreement, with the same basic terms and conditions otherwise as the original lease. In some cases, such as if rent is being paid weekly, the lease may become a week-to-week lease.

Connecticut Lease Agreement (Free) | 2025 Official

A Connecticut residential lease agreement (“rental agreement”) is a legal contract between a landlord overseeing a residential property and a tenant who wishes to rent it. A residential lease may, on or before move-in, additionally require a security deposit from the tenant as assurance against future property damage.

This information should be provided to the tenant on or before the commencement of the tenancy.

Common Interest Community Notice

Applicable 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:

Bed Bug Disclosure

Applicable 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 must also 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.

Move-In Checklist

Applicable 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 occupies the property. This enables accurate deductions from the security deposit upon move-out.

A landlord cannot deduct from the security deposit to repair any issue noted on the move-in checklist.

Notice of Elderly and Disabled Tenant Rights

Applicable 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. Certain types of evictions and rent increases are not permitted when a tenant falls into one of these protected categories. Landlords of properties which contain five or more units must provide every new or renewed tenancy with a disclosure from the Housing Commission which details these rights.

Lead-Based Paint Disclosure

Applicable 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:

Fill out and attach this lead-based paint disclosure form to the lease agreement.
Provide the tenant with an Environmental Protection Agency (EPA) approved pamphlet about the dangers of lead-based paint.
Provide any additional records or reports about the presence or hazards of lead-based paint in the unit. For multi-unit buildings with common areas, this includes information from building-wide evaluations.

Optional Disclosures and Addenda (Recommended)

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

Optional Disclosure	Purpose
Asbestos	Informs tenants about any asbestos hazards related to the property. Tenants can take precautions to reduce asbestos hazards by avoiding any disturbance of 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, along with any remediation efforts, to help limit landlord liability.
Non-Refundable Fees	Charges not agreed by the tenant in the lease may be refundable upon lease termination. For Connecticut landlords to charge a non-refundable fee, it must be disclosed and agreed as such in the lease.
Shared Utilities Arrangements	Discloses how charges are billed to individual tenants, when multiple rental units share a utility meter for the whole building or property. 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.
