security deposit return deadline connecticut law is shorter than most renters expect. Under Connecticut General Statutes § 47a-21, your landlord must return your deposit within 21 days after your tenancy ends, or within 15 days after you give written notice of your forwarding address — whichever date falls later. That 21-day rule is new.
Public Act 23-207 cut the old 30-day window down to 21 days, so older articles and even some landlord handbooks are out of date. If you moved out weeks ago and your money has not shown up, the security deposit return deadline connecticut sets may have already passed. Knowing the exact date matters, because Connecticut gives tenants a real financial remedy when landlords miss it.
How the Security Deposit Return Deadline Connecticut Uses Actually Works
The clock runs on two tracks. Track one starts when your tenancy terminates — usually your move-out date or the lease end date. Track one gives your landlord 21 days. Track two starts the day your landlord receives written notice of where to mail the check. Track two gives 15 days. The later of the two dates controls.
For example, say your lease ended June 1 and you emailed your new address on June 20. Twenty-one days from June 1 is June 22. Fifteen days from June 20 is July 5. In that case, July 5 is your deadline. However, if you gave your forwarding address before you moved out, the 21-day track almost always controls.
By that date, your landlord must send one of two things. Either the full deposit plus accrued interest, or the remaining balance plus a written itemized statement listing each deduction and its exact dollar amount. A vague note saying “kept for damages” does not satisfy the security deposit return deadline connecticut requires. The itemization must describe the nature and amount of each claimed loss.
Deposit Caps, Interest, and the Double-Damages Penalty
Connecticut limits how much a landlord can hold in the first place. Most tenants can be charged no more than two months’ rent. If you are 62 or older, the cap drops to one month’s rent. That age-based cap applies automatically. Typically, if you turn 62 mid-lease, you may be able to request the excess back in writing.
Your deposit also earns interest. The Banking Commissioner sets a deposit index each year, and the 2026 rate is 0.49%. Interest is owed annually on the anniversary of your tenancy, and all accrued interest must come back with your deposit.
| Rule | Connecticut standard | Statute |
|---|---|---|
| Return deadline | 21 days after tenancy ends, or 15 days after written forwarding address — whichever is later | § 47a-21(d)(2) |
| Maximum deposit (under 62) | 2 months’ rent | § 47a-21(b) |
| Maximum deposit (62 or older) | 1 month’s rent | § 47a-21(b) |
| 2026 interest rate | 0.49% (deposit index) | § 47a-21(i) |
| Penalty for violation | Twice the deposit amount | § 47a-21(d)(2) |
The penalty is the part landlords tend to forget. When a landlord blows the security deposit return deadline connecticut imposes without a valid legal reason, the statute makes them liable for twice the value of the deposit, plus any interest owed. On a $2,400 deposit, that is potentially $4,800. Courts do apply exceptions, so no result is guaranteed.
What to Do When Your Landlord Misses the Deadline
Start by locking in the forwarding-address date. Send your address by certified mail with return receipt, or by email you can print. That receipt proves when the 15-day track began. Without it, a landlord may claim they never got your address, and the security deposit return deadline connecticut applies becomes hard to prove.
Next, gather your evidence. Pull your move-in and move-out photos, your lease, your deposit receipt, and any text messages about the unit’s condition. Compare every deduction against normal wear and tear. In most cases, landlords cannot charge you for faded paint, worn carpet, or minor nail holes. Those are ordinary aging, not damage.
Then send one written demand letter. State your move-out date, your deposit amount, the date you provided your address, and the fact that the deadline has passed. Give a short response window, such as 10 days. As a result of a clear written demand, many landlords pay rather than face a doubled claim.

Frequently Asked Questions
Does the security deposit return deadline connecticut sets still run if I broke my lease?
Yes. The deadline applies whenever the tenancy terminates, however it ends. Your landlord may deduct unpaid rent it is legally entitled to, but it must still send an itemized statement on time.
What if my landlord sent an itemized list but no money?
A timely itemization satisfies part of the rule, so double damages may not apply. However, you can still challenge individual deductions in small claims court. Bring your photos and any repair estimates.
Can I skip the deadline problem by using my deposit as last month’s rent?
Typically no. Connecticut deposits are not automatic rent payments, and withholding rent can expose you to an eviction case. For example, a landlord could file for nonpayment even while owing you the deposit. Ask a legal-aid office first.
