Connecticut Security Deposit Law (Returns and Deductions)

Connecticut Security Deposit Law (Returns and Deductions)

Last Updated: December 26, 2025 by Thomas Krasomil

Connecticut landlords who understand their state’s security deposit laws often avoid common issues that surface during move-outs, like as confusion over returns, interest, or deductions, as well as missed statutory deadlines and improper handling of deposit funds.

This guide outlines everything property owners need to know about these regulations, including maximum amounts landlords can request, how to store deposits, required interest, legal grounds for deductions, returning deposits, handling disputes, and more.

Statutes Regulating Connecticut Security Deposits

Connecticut’s security deposit rules appear in Chapter 831 of Title 47a of the Connecticut General Statutes, which outline how landlords collect, store, and return deposits for residential rentals. Specifically, sections 47a-21, 47a-22, and 47a-22a, explain limits on deposit amounts, escrow requirements, interest, returns, and deductions.

Maximum Security Deposit Amounts Under Connecticut Law

Connecticut landlords set security deposits at no more than 2 months’ rent for most tenants, however state law lowers this limit to 1 month’s rent for tenants 62 or older. These rules apply across lease types and contract lengths without exception.

No Connecticut municipalities currently enforce local regulations that override the statewide limits.

Security Deposit Storage Regulations

Connecticut law requires landlords to keep each security deposit in an escrow account at a financial institution, where the funds earn interest for the tenant. While doing so, landlords must give written notice that identifies the institution holding the deposit.

For example, a landlord cannot place a tenant’s security deposit in a personal or operating account or use those funds for routine property expenses.

Security Deposit Interest in Connecticut

Connecticut landlords must keep every security deposit in an interest-bearing escrow account at a federally insured financial institution. Each year, the Connecticut Banking Commissioner sets the interest rate that landlords must use when calculating the interest tenants earn on their deposits.

Landlords apply that annual rate and return or credit the interest when they return the deposit. Tenants age 62 or older earn interest at the same rate, and landlords follow identical rules for all residential lease types.

Making Security Deposit Deductions

Security deposit deductions help landlords recoup unpaid rent, repair costs, and other lease-related expenses. Tenants sometimes fall short on rent or cause damage beyond normal wear and tear, and landlords rely on deposit funds to complete repairs and return the unit to its previous condition.

When Landlords Can Deduct

Connecticut landlords may draw from a tenant’s security deposit to:

  • Repair damage that exceeds normal wear and tear
  • Recover unpaid rent that remains due at move-out
  • Cover unpaid utility charges assigned to the tenant
  • Address cleaning costs needed to restore the unit’s prior condition
  • Replace items that the tenant damaged through misuse or neglect

When Landlords Can’t Deduct

Connecticut landlords may not draw from a tenant’s security deposit for the following reasons:

  • Routine cleaning associated with normal residential use
  • Expected aging or natural deterioration of property materials
  • Minor cosmetic issues that result from standard daily living
  • Maintenance or repairs that fall under landlord responsibilities
  • Damage caused by issues outside the tenant’s control

Necessary Documentation to Accompany Deductions

Connecticut landlords must give tenants a written, itemized list of deductions when they return the security deposit. State law does not require landlords to include receipts or invoices, but many property choose to include them to clarify repair and cleaning costs and help prevent disputes.

What to Do When Deductions are Greater Than the Deposit

Sometimes, tenant damage or unpaid rent exceed the amount held in the security deposit. In these cases, landlords should document every cost, send a written demand for payment, and give the former tenant a reasonable time to respond. Connecticut law does not set a specific deadline for pursuing these charges, so landlords should act decisively to protect their claims.

Landlords who are unable to collect the remaining balance themselves can send the debt to a collections agency or file a claim in their local Connecticut small claims court.

Returning Security Deposits to Tenants

Connecticut law outlines clear rules for returning any remaining portion of a tenant’s security deposit after eligible deductions, which helps landlords follow consistent practices and avoid misunderstandings.

Required Timeline for Return

Connecticut landlords must return the remaining deposit and provide an itemized list of deductions within 30 days after the tenancy ends or within 15 days after receiving the tenant’s forwarding address, whichever date comes later. The timeline starts once the tenancy ends and the landlord has the tenant’s new address.

Method for Return

Connecticut law requires landlords to send the what’s left of the deposit and the written, itemized deduction statement to the tenant-provided forwarding address. State rules do not mandate a specific payment method, so landlords commonly use a check or another reliable payment method.

Penalties for Late Return

Under Connecticut law, landlords who fail to return a security deposit on time or wrongfully withhold funds may be liable for double the amount wrongfully withheld. In addition, courts may award court costs and reasonable attorney’s fees when a landlord does not comply with the statutory requirements governing security deposit returns.

Security Deposit Disputes

When tenants disagree with how a landlord handles their security deposit, they have the right to raise a dispute. Tenants should start by asking for clarification in writing, then request supporting documentation or evidence for the deductions. If that effort fails, they may pursue mediation or file a claim in Connecticut’s small claims court.

Landlords should prepare for potential disputes by using move-in and move-out checklists, keeping up with accounting and bookkeeping, and setting clear terms in your lease agreement. Thorough documentation, strong knowledge of Connecticut laws, and close attention to required timelines can also help prevent misunderstandings.

Using Condition Reports to Document Damage

Security deposits in Connecticut are much easier to manage when expectations are clearly documented from the start. Detailed move-in and move-out condition reports give landlords and tenants a shared understanding of a unit’s condition, reducing confusion and helping avoid awkward disagreements later.

Many landlords now use property management software to create digital condition reports with photos and videos right from a smartphone, making inspections faster and more accurate.

FAQs: Connecticut Security Deposit Law

Can a landlord deduct painting from a security deposit in Connecticut?

Landlords in Connecticut may deduct painting costs only when a tenant causes damage that goes beyond normal wear and tear, such as deep marks or unauthorized colors. Routine repainting that occurs during regular use does not qualify for a deduction.

Are nail holes considered normal wear and tear in Connecticut?

Small nail holes usually count as normal wear and tear in Connecticut, so landlords cannot deduct for them. Larger holes or wall damage that results from improper hanging methods may justify a deduction when repairs go beyond what state law considers everyday use.

Does the landlord or tenant have to pay for carpet cleaning in Connecticut?

If carpet cleaning is needed because of normal wear and tear, landlords cannot charge tenants for the cost. When a tenant leaves behind stains, odors, or heavy dirt that requires special cleaning, landlords may deduct those reasonable expenses from the security deposit.

What happens if a landlord doesn’t return a security deposit within 30 days in Connecticut?

If a landlord does not return the deposit or an itemized statement of deductions within 30 days, the landlord may owe the tenant twice the amount wrongfully withheld. Courts may also award additional costs and reasonable attorney fees when landlords fail to comply with Connecticut’s requirements.
