Connecticut Residential Leases: Security Deposits and Landlord Obligations

Last updated: 10 April 2026 · BeforeYouSign Editorial Team

Connecticut law strictly regulates security deposits in residential leases, requiring landlords to hold deposits in interest-bearing escrow accounts and return deposits with interest within specified timeframes. Connecticut's deposit regulations (Conn. Gen. Stat. § 47a-21) are among the most tenant-protective in the US. Landlords must deposit security funds with the clerk of the court or in an interest-bearing escrow account, and they must return deposits within 30 days with an itemized list of any deductions. Failure to comply can result in liability for the full deposit plus interest, plus treble damages (three times the wrongfully withheld amount). Tenants in Connecticut have strong protections against improper deposit handling. Many disputes arise because landlords fail to place deposits in escrow, don't provide itemized deductions, or make improper deductions for normal wear and tear. Understanding your rights under Connecticut law can help you recover your full deposit and potentially additional damages if a landlord violates the law.

What is a Housing & Tenancy?

In Connecticut, a security deposit is a refundable payment required at lease signing. Connecticut law limits security deposits to two months' rent. Landlords must hold deposits in an interest-bearing escrow account (either at a court or at a bank) and must return deposits with interest within 30 days of lease termination. Deductions can only be made for actual damages beyond normal wear and tear.

Red flags to watch for

Landlord doesn't provide written notice of where the deposit will be held or the account details

Connecticut law requires landlords to disclose the escrow account location and details; failure to disclose is a violation.

Lease allows security deposits exceeding two months' rent

Connecticut law limits deposits to two months' rent; deposits exceeding this are capped and excess must be refunded.

Landlord fails to return the deposit or provide an accounting within 30 days of lease termination

Connecticut law requires return within 30 days; failure is a direct violation with liability for treble damages.

Deductions are listed without itemization or documentation (e.g., 'damages $800' with no detail)

Connecticut law requires itemized deductions showing what was damaged and the repair cost; vague deductions are invalid.

Deductions include normal wear and tear or charges for cleaning or repainting beyond tenant damage

Connecticut law limits deductions to actual damage caused by the tenant; maintenance is the landlord's responsibility.

Landlord doesn't pay interest on the deposit or claims escrow doesn't require interest

Connecticut law requires interest payment (typically 5-7% annually depending on the account type); lack of interest is a violation.

Your legal rights

Connecticut General Statutes § 47a-21 sets strict rules for security deposits. Landlords must hold deposits in escrow with a court or bank, and must return deposits with interest within 30 days. Improper handling results in liability for the full deposit plus interest plus treble damages (three times the wrongfully withheld amount). Tenants have the right to an itemized deduction list and can challenge improper deductions. Normal wear and tear is not deductible.
