Connecticut Sublease Agreement

Last Updated: December 8, 2025 by Cu Fleshman

A Connecticut sublease agreement sets up an arrangement that lets a tenant bring in a subtenant while the original lease continues to control the rental terms. This type of agreement helps property owners facilitate a smooth transition between tenants, keep every party accountable to the same rules, and maintain lawful occupancy throughout the rental period.

Does a tenant need a landlord’s permission to sublease in Connecticut?

Connecticut has no statute that directly addresses residential subleasing, so a tenant needs the landlord’s permission only when the lease requires it. Clear sublease terms give property owners a reliable way to determine who may occupy the unit and how the rental relationship will continue.

Landlords strengthen their rental terms by addressing subleasing in their Connecticut lease agreement through a customized, legally sound template. To cover subleasing in future leases, property owners can rely on a legally reviewed lease agreement builder to draft the contract on their behalf.

Information to Include in a Connecticut Sublease

Landlords benefit when they treat subleases the same way they handle any standard lease, because clear terms guide the rental relationship and set expectations for all parties involved. Landlords should include the following information within a Connecticut sublease:

Names of landlord and sublessor: Identify the property owner and the original tenant who plans to bring in a subtenant under clearly defined terms.

Rental unit address: List the full address of the rental property so every party understands exactly where the agreement applies.

Length of the sublease agreement: Confirm the specific start and end dates to ensure the sublease lines up with the original lease period.

Rent amount: Outline the monthly rent the subtenant must pay and explain when and how those payments will be made.

Division of utilities: Clarify how the original tenant and subtenant share utility responsibilities and can reference a landlord-tenant utility agreement for added structure.

Security deposit information: State whether the subtenant will pay a security deposit and explain how those funds follow Connecticut security deposit laws.

Maintenance protocols: Outline how the original tenant and subtenant handle routine upkeep and repair requests, as well as more extensive rental property maintenance.

Property policies: Restate rules from the original lease so the subtenant understands expectations regarding conduct, guests, and daily use of the rental unit.

Early termination terms: Define the conditions under which either party may terminate the sublease early and specify any fees or notice requirements associated with that decision.

Landlord’s right to entry: Explain when the property owner may enter the rental property and reinforce the notice rules already set in the primary lease.

Renter’s insurance: Clarify whether the subtenant must carry renter’s insurance and list the coverage requirements the property owner expects.

Landlord’s consent to sublease: Confirm that the property owner approved the sublease and recognizes the subtenant as an authorized occupant under the agreed terms.

Subtenant’s obligation to comply with the master lease: Confirm that the subtenant agrees to comply with all terms of the original lease and to respect the standards the property owner has already set.

Move-in condition checklist: Include a detailed walkthrough record or a move-in condition report to document the unit’s condition at the start of the sublease.

Emergency contact information: Collect current contact details to reach the original tenant or subtenant quickly if an urgent issue arises.

Guest policy: Restate the property’s rules on guests and clarify how long visitors may stay before the subtenant needs approval.

Copy of master lease: Accompany the sublease so the subtenant understands which terms still apply.

Signatures: Sign the agreement, and landlords may allow each participant to e-sign the document to speed up the subleasing process.

Additional attachments: Any additional documents, such as property rules or inspection forms, should accompany the sublease to provide clear, complete expectations.

Taxes Implications for Short-Term Subleases

A short-term sublease in Connecticut may trigger state lodging taxes if the arrangement qualifies as a “short-term rental.” Connecticut imposes a 15% room occupancy tax on rentals for fewer than 30 consecutive calendar days (Conn. Gen. Stat. § 12-407).

Landlords should also confirm whether their local municipality imposes additional short-term lodging taxes, as local tax rates and rules can vary across the state.
