Connecticut security deposit law
Short answer: A Connecticut landlord has 21 days after the tenancy ends, or 15 days after getting the tenant's forwarding address in writing (whichever is later), to return the deposit plus interest with an itemized statement of any damages. Deposits are capped at two months' rent, or one month for tenants 62 and older.
| Deadline to return the deposit | 21 days after the tenancy ends, or 15 days after the landlord receives the tenant's written forwarding address, whichever is later. |
|---|---|
| Limit on how much a landlord can charge | Two months' rent for tenants under 62. One month's rent for tenants 62 or older; a tenant who turns 62 can ask for the extra back. |
| Itemized list of deductions | Yes. A written statement itemizing the nature and amount of each damage charge. |
| Interest on the deposit | Yes. At least the yearly 'deposit index' rate published by the state Banking Commissioner, paid or credited toward rent every year on the tenancy anniversary, and paid in full at move-out. |
| Penalty if the landlord breaks the rules | A landlord who breaks the return rules owes twice the deposit. If the only problem is skipping the interest, the penalty is $10 or twice the interest, whichever is greater. |
| What the tenant has to do | Send the landlord your forwarding address in writing when you move out. |

Good to know
- The landlord must put the deposit in an escrow account at a Connecticut bank right away, and tell the tenant in writing within 30 days how much is held and at which bank.
- When a property is sold, the deposits and interest must be transferred to the new owner, who becomes responsible for them.
Tips for landlords
- Do a written move-in inspection and have the tenant sign it. Take dated photos of every room, including inside appliances and closets.
- Collect the tenant's forwarding address in writing at move-out.
- Put the itemized list and the refund in the mail well before the deadline, and keep proof of mailing.
- Normal wear and tear (faded paint, light carpet wear, small nail holes) usually can't be charged. Damage beyond that can.
Tips for tenants
- Take your own dated photos and video on move-in day and move-out day.
- Give your landlord your forwarding address in writing, and keep a copy.
- If the deadline passes, send a written demand letter that cites the law above before going to small claims court.
