Security deposit return deadline in Connecticut
A Connecticut landlord has 21 days to return the deposit or account for what is kept.
Deadline
21 days
Reduced from 30 days to 21 by P.A. 23-207. Whichever is later, so a late forwarding address extends it.
“Not later than twenty-one days after termination of a tenancy or fifteen days after receiving written notification of such tenant's forwarding address, whichever is later”
When the clock starts
Most states run the deadline from the later of two events: the tenancy ending and the tenant actually handing back possession. A tenant who stops paying in March but leaves in May usually triggers the clock in May, not March. Several states add a third condition — the tenant supplying a forwarding address in writing — and in those states the deadline does not begin until that arrives.
For Connecticut specifically: Reduced from 30 days to 21 by P.A. 23-207. Whichever is later, so a late forwarding address extends it.
What has to be in the letter
Returning the money is only half of it. Nearly every state that sets a deadline also requires an itemised statementwhen anything is withheld, and the usual penalty for a missing or late statement is not a fine — it is forfeiting the right to withhold anything at all. A landlord with $900 of genuine damage and no timely itemisation frequently recovers nothing.
Include, at minimum:
- Each deduction on its own line, described specifically — “replace broken bedroom blind, $85”, not “repairs, $300”.
- Invoices, receipts or written estimates. Some states require them outright; the rest reward you for having them.
- The arithmetic: deposit held, deductions totalled, refund enclosed.
- Proof of delivery, sent inside the deadline — first-class mail to the forwarding address, certified where the state asks for it.
Normal wear and tear is not damage
The single most common reason a deduction fails is that it was really wear and tear. Carpet flattened by four years of walking, paint faded by sunlight, and scuffs behind furniture are the cost of letting property, not the tenant’s bill. Damage is something beyond ordinary use: a burn, a hole, a pet stain through to the underlay, a missing door. If the item would have needed replacing at the end of its useful life anyway, charging the full replacement cost to one tenant rarely survives scrutiny.
How this compares
Deadlines across the United States run from 14 days to 60, and two states set none at all. Connecticut sits at 21 days. See every state side by side.

Common questions
- How long does a landlord have to return a security deposit in Connecticut?
- 21 days after the tenancy ends and the tenant gives up possession, under Conn. Gen. Stat. 47a-21(d)(2). Reduced from 30 days to 21 by P.A. 23-207. Whichever is later, so a late forwarding address extends it.
- What happens if a Connecticut landlord misses the deadline?
- Reduced from 30 days to 21 by P.A. 23-207. Whichever is later, so a late forwarding address extends it.
- Can a Connecticut lease change the deposit return deadline?
- Generally no — a statutory deadline is a floor that a lease cannot shorten, though a few states expressly let a lease extend it. Where Connecticut permits a longer period it is noted above. A lease clause that gives the landlord longer than the statute allows is unenforceable.
