Utah's main security deposit deadline is 30 days after the day you vacate and return possession of the rental property. By then, the owner or owner's agent generally must mail or deliver the deposit balance, the balance of any prepaid rent, and a written notice itemizing and explaining each deduction.
Do not flatten the trigger
The deadline is not just "30 days after move-out." For a clean Utah record, keep proof of both parts:
- the date you vacated
- the date you returned possession, keys, access devices, or control of the rental
If those dates are disputed, the deadline can become harder to prove.
What the owner must send
If money is withheld, the owner should send a written notice that itemizes and explains each deduction. The notice may be mailed or delivered to your last known address, or sent electronically by a means you provided.
Watch this step
If the owner misses the 30-day rule, serve Utah's statutory deposit-disposition notice and keep proof.
That notice gives the owner 5 business days after service to comply. It should identify the parties, the date you vacated, the failure to comply, and the address where the owner may send the required refund and notice.
Why the 5-business-day period matters
If the owner still does not comply after the statutory notice period, Utah law can allow the renter to recover the full deposit, the full prepaid rent, and a $100 civil penalty. That remedy path depends on the notice step, so do not skip it.

Utah's deadline is only the first step. The system keeps the statutory notice and 5-business-day follow-up in the right order.
