Last Updated: February 2, 2026 by Noel Krasomil

Before you say yes to renting out the spare room in your home, remember to write up a quick room rental agreement. Connecticut landlords use these contracts to prevent misunderstandings, clarify expectations, and hold everyone accountable. Whether you’re looking to make some extra cash or helping out a friend who needs a place to stay, a detailed Connecticut lease agreement can eliminate stress and provide legal protection. 

Use this guide to create a room rental agreement in Connecticut that protects your best interests from day one. In this article, we’ll discuss mandatory disclosures, the state’s must-know rental laws, and how property management software can simplify your life as a landlord.

Room Rental Laws

Before diving into landlord-tenant laws in Connecticut, here’s a quick recap of a rental property owner’s responsibilities in the Constitution State: 

  • Maintain safe, habitable housing.
  • Make all mandatory disclosures.
  • Notify tenants before entering their room.
  • Avoid all methods of landlord harassment.

Next, we’ll discuss the first step to creating a room rental agreement in Connecticut: choosing your contract type. 

Different Types of Room Rental Agreements in Connecticut

Here’s what landlords use for their Connecticut room rental agreement: 

  • Verbal agreement: We recommend against verbal agreements. Always put everything in writing rather than relying on word of mouth. 
  • Fixed-term lease: These long-term written contracts define a start and end date, typically lasting 6 months to 1 year. 
  • Month-to-month lease: “Tenancy at will” agreements automatically renew each month, and both parties can end them at any time by giving written notice. 

To choose the right lease agreement type, consider your relationship with the tenant, your specific situation, and the length of the tenancy.

Required Landlord Disclosures

When creating your room rental agreement in Connecticut, include these five mandatory disclosures: 

  1. Lead-based paint: Federal law requires landlords leasing properties built before 1978 to disclose any lead-based paint or lead-based paint hazards (42 U.S.C. § 4852d). 
  2. Landlord contact information: Include the landlord’s name and contact details, such as a valid mailing address, in the lease agreement (Conn. Gen. Stat. § 47a-6).
  3. Common interest community: If your rental property belongs to a common interest community, you must inform tenants in writing (Conn. Gen. Stat. § 47a-3e).
  4. Sprinkler system: Tell tenants if their room has a sprinkler system, and include the most recent inspection date in your lease (Conn. Gen. Stat. § 47a-3f).
  5. Bed bugs: Notify tenants if bed bug infestations affect the property (Conn. Gen. Stat. § 47a-7a).

Next, we’ll review Connecticut’s rental laws in detail. 

Security Deposit Rules

Maximum security deposit: If tenants are under 62 years old, you can charge up to 2 months’ rent. If tenants are 62 or older, you can charge up to 1 month’s rent (Conn. Gen. Stat. § 47a-21b).

Security deposit receipt: If tenants pay in cash, give them a receipt mentioning the transaction’s date, the amount they paid, and its purpose (Conn. Gen. Stat. § 47a-3a).

Deduction tracking: List and itemize all deductions in writing (Conn. Gen. Stat. § 47a-21d).

Security deposit return: Return the security deposit, plus accrued interest, within 30 days of move-out or 15 days after the tenant provides their forwarding address in writing, whichever is later (Conn. Gen. Stat. § 47a-21d).

Pet deposits: If you collect a pet deposit, you must return it after tenants provide a signed statement saying they no longer have the pet (Conn. Gen. Stat. § 47a-21d). 

Rent Payment Rules

Late rent fees: Connecticut caps late fees at the lesser of $5 per day up to a maximum of $50, or 5% of the overdue balance (Conn. Gen. Stat. § 47a-15a).

Right to withhold rent: No law allows tenants to withhold rent, but they may use repair-and-deduct remedies in specific situations. 

Grace period: State law mandates a 9-day grace period for fixed-term and month-to-month leases, and a 4-day grace period for week-to-week agreements (Conn. Gen. Stat. § 47a-15a).

Pet rent: You can charge a reasonable pet rent if you outline it in your lease, but not for service animals or Emotional Support Animals (ESAs) (42 U.S.C. § 3601 et seq.).

Rent Payment Increase Rules

Rent payment increase frequency: Landlords can increase rent after the lease period ends, but they must provide 45 days’ written notice before doing so (Conn. Gen. Stat. § 47a-4e).

Rent payment increase maximum: State law doesn’t cap rent increase amounts. 

Rent control/stabilization: If a landlord raises a tenant’s rent and the tenant believes the increase is excessive, they can take the issue to court. After the hearing, local authorities can intervene to limit the amount (Conn. Gen. Stat. § 7-148d).

Room Rental Agreement Breaches

Failure to pay: Landlords can terminate the room rental agreement and initiate the eviction process if tenants don’t pay rent (Conn. Gen. Stat. § 47a-15a).

Lease violations: Provide written notice and give the tenant a 15-Day Cure or Quit Notice. If the tenant breaches the lease in the same way again within 6 months, landlords can skip the notice period and pursue eviction (Conn. Gen. Stat. § 47a-15).

Self-help evictions: Connecticut law strictly forbids landlords from using self-help eviction methods, including changing the locks (Conn. Gen. Stat. § 53a-214).

Terminating a Room Rental Agreement

Month-to-month: Give at least 3 days’ notice to end a month-to-month room rental agreement (Conn. Gen. Stat. § 47a-23).

Fixed-term: If both parties agree to end the lease early, you can terminate a fixed-term lease before its end date without penalty.

Room abandonment: You must notify tenants before taking possession of the room, and mitigate damages by attempting to re-rent it (Conn. Gen. Stat. § 47a-11b).

Tenant’s right to terminate: Victims of domestic violence or sexual assault can end their lease early by providing 30 days’ written notice (Conn. Gen. Stat. § 47a-11e).

Landlord Access Laws

Immediate access: Landlords may enter a tenant’s room without asking to address an emergency, comply with a court order, or reclaim an abandoned room (Conn. Gen. Stat. § 47a-16).

Landlord harassment: State law prohibits landlords from abusing their entry right or using it unreasonably to harass tenants (Conn. Gen. Stat. § 47a-16c).

Advance notice: In Connecticut, landlords must give reasonable written or oral notice before entering the tenant’s room (Conn. Gen. Stat. § 47a-16c).

Lease Agreement Renewal and Termination

Required renewals: State law doesn’t require landlords to renew a room rental agreement in Connecticut (Conn. Gen. Stat. § 47a-23).

Required notice: Provide 3 days’ notice to terminate tenancy-at-will agreements (Conn. Gen. Stat. § 47a-23).

Month-to-month considerations: If a fixed-term lease expires and the tenant continues to rent the room without signing a new agreement, Connecticut law treats the tenancy as month-to-month (Conn. Gen. Stat. § 47a-23).

Consider using property management software to help you follow these legal guidelines, keep tenants happy, and save time.
