Missouri security deposit rules
How Missouri deposit returns generally work
Missouri law, RSMo 535.300, caps residential security deposits at two months’ rent and generally requires the landlord, within 30 days after the tenancy terminates, to return the full deposit or mail the tenant a written itemized list of damages along with the remaining balance. Deductions are limited to unpaid rent, restoring the unit beyond ordinary wear and tear, qualifying carpet cleaning, and losses from inadequate notice to terminate, and the statute provides that a tenant shall recover twice any amount a court finds was wrongfully withheld.
RSMo 535.300.3 generally requires the landlord, within 30 days after the tenancy terminates, to return the full deposit or furnish a written itemized list of damages with the balance; mailing to the tenant’s last known address satisfies the requirement.
Deposits are capped at two months’ rent, and § 535.300.4 limits withholding to unpaid rent, restoring the unit with ordinary wear and tear excepted (including qualifying lease-based carpet cleaning), and actual damages from inadequate notice to terminate.
The tenant may attend the move-out inspection after reasonable notice, and § 535.300.6 provides that the tenant shall recover as damages twice the amount wrongfully withheld in violation of the section.
Watch your own deadline: Because the landlord complies by mailing the itemized list and any payment to your last known address, give the landlord your current mailing address in writing promptly and keep proof of when you sent it. RSMo 535.300.7 also states that a tenant may not apply the deposit in lieu of rent.
Check coverage: Section 535.300.8 excludes money denominated as a pet deposit. Since August 28, 2025, RSMo 441.043 bars counties and cities from limiting the amount of security deposit a landlord may require. Missouri small claims courts hear claims up to $5,000, exclusive of interest or costs.
