How long does a landlord have to return a security deposit in Missouri?
Under Missouri law, landlords must return your security deposit within 30 days of your move-out date. This includes providing an itemized list of any deductions (for damage beyond normal wear and tear, unpaid rent, or cleaning costs). If your landlord misses this deadline or fails to provide an itemized list, they may be in violation of Missouri state law.
Missouri Security Deposit Penalties
Missouri provides strong tenant protections. If your landlord fails to return your deposit on time, you may be entitled to recover up to 2x deposit. Based on the average US security deposit of $1,200, this means you could recover up to $2,400.
Common Reasons Landlords Illegally Withhold Deposits
- Claiming damage beyond normal wear and tear (faded paint, minor scuffs, carpet wear)
- Charging excessive cleaning fees not specified in the lease
- Deducting for “repairs” to pre-existing conditions
- Claiming unpaid rent or utilities without documentation
- Failing to provide itemized deductions within 30 days
- Simply hoping the tenant won’t fight back
How to Get Your Security Deposit Back in Missouri
- Document everything. Take photos of the unit at move-out, keep copies of your lease, and save any written communication with your landlord.
- Wait for the deadline to pass. Missouri gives landlords 30 days to return your deposit.
- Send a formal demand letter. A written demand letter citing Missouri’s specific laws creates a legal paper trail. Use our free tool above to check your case.

Frequently Asked Questions
Do I need a lawyer for a security deposit dispute in Missouri?
No. Security deposit cases are typically handled in small claims court where lawyers are not required (and often not allowed). A formal demand letter is usually enough to resolve the dispute before it ever gets to court.
How much can I recover in Missouri?
Up to 2x deposit. On an average $1,200 deposit, that could be as much as $2,400.
What if my landlord still refuses after the demand letter?
File a case in Missouri small claims court. The certified mail receipt from your demand letter becomes evidence that you tried to resolve it informally — judges look favorably on this.
