Connecticut Security Deposit Law: How to Get Your Deposit Back
If you rent in Connecticut, the law gives you specific rights when you move out — a deadline for your landlord to return your deposit, rules on deductions, and a path to push back if they don't. Here's exactly how it works, and how to protect yourself.
Connecticut-specific rules to know
Return within 21 days (raised from 15 days); deposit capped at 2 months' rent (1 month for tenants 62+). Annual interest required. No-fault termination: itemised statement within 30 days of receiving forwarding address.
What Connecticut law requires your landlord to do
Under Conn. Gen. Stat. § 47a-21, a Connecticut landlord generally must return your deposit within 21 days and provide a written, itemized list of any amounts withheld. They may not deduct for ordinary wear and tear — only for damage beyond normal use, unpaid rent, or other charges the lease and statute allow.
What to do if your landlord won't return your deposit in Connecticut
1. Know your deadline
In Connecticut, the return window is 21 days (Conn. Gen. Stat. § 47a-21). Mark the date you moved out and count forward.
2. Send a written demand
Email and mail a dated letter requesting your full deposit, referencing the 21-day deadline under Conn. Gen. Stat. § 47a-21. Keep proof of delivery. Renter's Vault generates a Connecticut-specific letter with the right statute citation filled in.
3. Gather your evidence
Move-in and move-out photos with timestamps and location are the difference between your word and theirs. Attach your photo record and any move-in checklist.
4. Escalate to small claims
If the landlord misses the deadline or won't respond, you can file in small claims court. Bring your dated demand letter and photo evidence.
