In Connecticut, a landlord generally must return your security deposit plus accrued interest within 21 days after termination, or 15 days after the landlord receives your written forwarding address if that is later.
This is one of the most important rules in a deposit dispute, because once that deadline passes, the landlord's position can change quickly.
What the Landlord Must Do
Within that timing window, the landlord generally must:
- return your deposit plus accrued interest, or
- provide a compliant written itemized statement if deductions are claimed
If neither one happens on time, the problem gets much bigger.
When the Clock Starts
Connecticut's timing works like this:
- 21 days after termination, or
- 15 days after the landlord receives your written forwarding address if that is later
This matters more than people think.
A lot of disputes come from:
- unclear termination dates
- weak proof of move-out timing
- missing written forwarding-address records
- confusion about whether interest was included
If the timeline is clear, everything else gets easier.
Do the forwarding-address step in writing and keep proof. Connecticut should not be treated as a state where missing the address automatically destroys every right, but the address can control the later timing path and make your deadline argument cleaner.
Why This Rule Matters
This is often the turning point in the dispute.
Before the deadline:
- the situation is still open
- deductions may still be asserted
After the deadline:
- the landlord's position may get weaker
- your position often gets much stronger
Once the timeline is clean and the deadline is missed, the dispute usually starts looking very different.
What If the Deadline Is Missed?
If your landlord does not act within the required time:
- the landlord may face liability for twice the amount of the security deposit if the deposit plus accrued interest still has not been returned and no compliant written itemization has been sent
- there may be a smaller penalty if the only violation is unpaid accrued interest
At that point, the question often shifts from:
"what can they charge?"
to:
"did they follow the rules at all?"
Common Issues Around the Deadline
Most problems happen when:
- no written itemized statement is provided
- deductions are vague or unsupported
- the deposit is returned without accrued interest
- the deposit is returned late
- communication about the forwarding address is unclear
- the landlord sends a partial refund without explaining the balance
These are exactly the situations that can be challenged.
What To Do Next
If the deadline has passed:
- confirm your move-out timeline
- confirm whether and when you sent a written forwarding address
- gather your documentation
- send a clear, formal demand
Build Your Case

Most situations do not need to go this far, but if they do, having your timeline and documentation in place puts you in a much better position.
TL;DR
If your landlord has not returned your deposit:
- check how Connecticut's 21-day / 15-day rule applies to your facts
- confirm your move-out date and possession return
- preserve written forwarding-address proof
- look for a compliant written itemization
- check whether accrued interest was included
- gather your evidence
- send a proper demand letter
This is the point where many disputes turn in the renter's favor.
You can work through this yourself using the steps above.
