Connecticut Landlord-Tenant Laws (2026): Deposits, Notice, and Tenant Rights

Connecticut Landlord-Tenant Laws (2026): Deposits, Notice, and Tenant Rights
Connecticut landlords may collect up to 2 months' rent as a security deposit (1 month for tenants 62 and older) and must return it within 21 days of move-out. Landlords must give reasonable advance notice before entering, and month-to-month tenancies end through a formal notice-to-quit process, not a rolling 30-day notice.
Security deposits in Connecticut
Connecticut caps the security deposit at 2 months' rent for most tenants. If the tenant is 62 years of age or older at the time the lease is signed, the cap drops to 1 month's rent. Landlords may deduct unpaid rent, damage beyond normal wear and tear, and other losses permitted by the lease. They must return the deposit (with an itemized deduction statement if anything is withheld) within 21 days after the tenant vacates, or within 15 days after receiving the tenant's forwarding address, whichever comes later. Public Act 23-207 shortened this deadline from 30 days, effective October 1, 2023. Missing the deadline can forfeit the landlord's right to make deductions.
| Detail | Rule |
|---|---|
| Standard deposit cap | 2 months' rent |
| Cap for tenants 62 or older | 1 month's rent |
| Return deadline | 21 days (or 15 days after forwarding address, whichever is later) |
| Itemized statement required | Yes, if any deduction is made |
Allowed deductions include unpaid rent, costs to repair damage caused by the tenant (beyond normal wear and tear), and other losses authorized by the rental agreement. Connecticut does not require landlords to hold deposits in a separate interest-bearing account for standard residential tenancies.
When can a landlord enter? Notice rules
Connecticut law requires landlords to give "reasonable notice" before entering a rental unit. There is no fixed minimum number of hours set in the statute, unlike the 24- or 48-hour rules in many other states. In practice, courts and the Connecticut Department of Housing treat at least 24 hours' notice as reasonable for non-emergency entry. Entry for showing the unit to prospective tenants or buyers should also follow this reasonable-notice standard and take place during normal business hours.

Emergency entry (a fire, burst pipe, or similar urgent threat to the property or the tenant's safety) does not require advance notice. Landlords may not abuse the entry right to harass tenants. Repeated unannounced entries, or entries for an improper purpose, can support a tenant's claim for damages under CGS 47a-16a.
Ending a lease: notice to vacate
Connecticut does not use a rolling 30-day notice to end a month-to-month tenancy. Instead, either party starts the process by serving a formal notice-to-quit. A 3-day notice to quit is the first step in an eviction proceeding (called "summary process" in Connecticut). For a month-to-month tenancy being ended without fault, the notice period is tied to the tenancy interval rather than a fixed number of days.
Because Connecticut's termination process is tied to summary-process eviction rules rather than a simple advance-notice period, tenants and landlords should review CGS 47a-23 carefully. For nonpayment of rent or a lease violation, a landlord must serve a proper notice-to-quit and then file for summary process in housing court. See the Connecticut eviction notice page for the specific notice periods and form requirements for each cause type.
Repairs and the warranty of habitability
Under CGS 47a-7, Connecticut landlords must maintain rental units in a condition fit for human habitation. This means keeping the structure weathertight, the plumbing and heating in working order, common areas safe and clean, and all electrical and mechanical systems in compliance with housing and health codes. The warranty cannot be waived in a lease.

If a landlord fails to make repairs affecting essential services (heat, hot water, electricity, plumbing), a tenant may use the repair-and-deduct remedy under CGS 47a-13. The tenant must give the landlord written notice and a reasonable time to fix the problem. If the landlord does not act, the tenant may arrange the repair and deduct the cost from rent, within the limits set by statute. Tenants may also pursue rent escrow through housing court or report violations to the local housing code authority.
Rent, late fees, and rent control
Connecticut caps late fees at $5 per day with a maximum of $50, or 5% of the monthly rent amount, whichever is greater. Monthly tenants also have a 9-day grace period before a late fee may be charged. These protections were added or clarified in the 2024 legislative session.
There is no requirement for advance written notice before a rent increase in Connecticut, but it is considered best practice and is implied by the obligation to give notice before changing lease terms. For a month-to-month tenancy, a rent increase would typically be presented with the notice-to-quit that starts the renewal process.
Connecticut does not have statewide rent control and there are no municipal rent-control ordinances currently in effect anywhere in the state. Landlords may set rents at market rates and increase them as permitted by the lease.
If you have a landlord-tenant dispute in Connecticut
If a landlord withholds your deposit without justification or misses the 21-day return deadline, your first step is to send a written demand letter. Keep copies of all communications, photos of move-out conditions, and proof you gave a forwarding address. Small claims court (housing division) handles deposit disputes up to $5,000 and is the fastest path to recovery.

For habitability or repair disputes, document the condition in writing and notify the landlord with a specific request and deadline. If the landlord does not respond, contact your local housing code inspector. Code complaints are official, documented, and can support a later court claim. The Connecticut Fair Housing Center (ctfairhousing.org) provides guidance on discrimination and habitability issues. Connecticut Legal Services (ctlawhelp.org) offers free assistance to qualifying tenants.
For complex disputes, such as wrongful eviction or retaliation, consult a licensed attorney. Connecticut has anti-retaliation protections under CGS 47a-20: a landlord may not raise rent, reduce services, or initiate eviction because a tenant exercised a legal right (like filing a code complaint).
This article is general legal information, not legal advice. Landlord-tenant rules vary by state and city and change, and some cities add their own ordinances. For advice about a specific situation, consult a licensed attorney or your state housing agency.
