Missouri Security Deposit Deadline

Missouri security deposit deadline rules, including the 30-day timing rule, last-known-address mailing, itemized list, and inspection notice.

Missouri landlords generally have 30 days after the tenancy ends to return the security deposit or send an itemized list of deductions with any remaining balance.

Give a good mailing address

It helps to give your landlord a current mailing or forwarding address in writing and keep proof that you sent it. Missouri allows the landlord to comply by mailing the deposit response and any payment to the tenant's last known address.

That is not a trap. It is a practical record issue. If the landlord says something was mailed, you want to be able to show what address you gave and when you gave it.

Missouri's deadline runs 30 days after termination of the tenancy. In plain English, focus on proving when the rental relationship ended and when you gave the place back.

What the landlord should send

Within the 30-day period, the landlord should either:

If the landlord keeps money, vague statements are not enough. The list should identify what is being charged and how much is being kept.

A missing or vague itemized list can weaken the landlord's position. Compare the list to your photos, inspection notes, lease, receipts, and Missouri's deduction categories.

You have a right to be present for the inspection

Missouri requires the landlord to give reasonable notice of the move-out inspection date and time, either in writing or in person. You have the right to be present.

Save the notice. If you can attend, take notes and compare any later deductions to what was actually discussed or seen at the inspection.

Inspection proof matters after the deadline because it helps answer whether the deduction was actually tied to damage, ordinary wear, carpet cleaning, rent, or another supported category.

If the deadline has passed and the response is still missing or incomplete, the next step is usually a written notice that puts the date, address proof, itemized-list problem, inspection record, deduction issue, and amount due in one place.
