Missouri is one of the few states that places a hard cap on security deposits—a maximum of two months’ rent. This protects tenants from excessive upfront demands. In return, landlords have a strict 30-day deadline to return the deposit with an itemized statement, and must provide the statement by first-class mail. Violations carry a 2x penalty plus attorney’s fees.

The Short Answer

Return deadline: 30 days after lease termination
Deposit cap: 2 months rent maximum
Penalty for wrongful withholding: 2x the amount wrongfully withheld, plus attorney’s fees
Key requirement: Written itemized statement sent by first-class mail

Security Deposit Cap

Missouri law limits security deposits to two months’ rent. If your lease calls for a deposit higher than this, you can challenge it. Some landlords also charge a separate “cleaning fee”—verify in your lease whether this counts toward the deposit cap or is separate.

The 30-Day Return Deadline

Landlords must return the security deposit—or the remainder after lawful deductions—within 30 days after the lease terminates. Missouri does not extend this deadline based on the tenant providing a forwarding address; the clock starts on lease termination, period. If the landlord needs more time to document damages, they should return the deposit and pursue damages separately through small claims court.

What Can a Missouri Landlord Legally Deduct?

Missouri permits landlords to deduct for:

Unpaid rent
Damage to the unit beyond normal wear and tear
Unpaid utilities (if tenant is liable per the lease)
Painting, repairs, or replacement of fixtures damaged by the tenant
Professional cleaning (only if the unit was left in unreasonable condition)

Landlords may not deduct for:

Routine maintenance
Normal wear to paint, carpet, or flooring
Carpet cleaning if reasonably clean upon move-out
Damage that existed before the tenant moved in
General wear to appliances and fixtures

What Is Normal Wear and Tear in Missouri?

Missouri courts follow a commonsense standard: would a landlord expect normal deterioration from ordinary use?

Cannot deduct:

Faded paint from sunlight
Worn carpet in hallways
Missing nails or small nail holes
Loose hinges or doorknobs
Stains from normal cooking or cleaning use

Can deduct:

Large holes or gouges in walls
Broken windows or glass doors
Major stains, burns, or damage to carpet
Missing or broken appliances
Water damage or mold from tenant negligence

Penalties for Wrongful Withholding

If a landlord violates Missouri’s security deposit law—by withholding without justification or failing to return within 30 days—the tenant can recover twice the amount wrongfully withheld, plus attorney’s fees and court costs. Like Wisconsin, this 2x penalty is strict and does not require proof of intent to defraud. A good-faith mistake still triggers the multiplier.

How to Get Your Deposit Back in Missouri

Notify the landlord of your move-out date: Provide written notice as required by your lease.
Clean thoroughly: Leave the unit in “normal” condition; take photos as proof.
Document your forwarding address: Give your address in writing so the itemized statement reaches you.
Wait 30 days: Mark your calendar. Missouri’s deadline is firm.
Check the itemized statement: The statement must be sent by first-class mail and must list every deduction with an explanation.
Verify deductions: Are they for damages beyond normal wear? Do they match the unit’s condition when you moved in?
File a claim if needed: Missouri small claims court jurisdiction is $5,000. Gather photos, the lease, move-in/move-out inspection reports, and the landlord’s itemized statement.

Key Statute

Mo. Rev. Stat. § 535.300 — The full statute governing security deposits in Missouri, including the 2-month cap, 30-day return deadline, and itemization requirements.

Real Situations in Missouri

In Kansas City, a tenant moved out of a downtown apartment after two years and provided a forwarding address. The landlord held the deposit for 35 days before returning it—five days past the 30-day deadline. The landlord claimed to have deducted for new carpet, but the invoice was dated five days after the tenant vacated and lumped all charges into a vague “flooring restoration” line item. Under Mo. Rev. Stat. § 535.300, the tenant can recover double the amount wrongfully withheld plus attorney’s fees, a claim worth pursuing even for a modest deposit.

A St. Louis landlord collected a $2,000 deposit from a tenant for a three-bedroom house and returned only $1,200 with an itemized statement claiming $500 for painting and $300 for “general repairs.” The statement provided no receipts, no repair invoices, and no itemization of specific repairs. The tenant argued these deductions violated normal wear and tear standards—the unit had ordinary paint fading and minor scuffs. Missouri courts would likely find this withholding improper because the landlord failed to provide detailed justification, allowing the tenant to recover $4,000 (2x the $2,000 wrongfully held) plus attorney’s fees.

A Springfield tenant’s landlord never sent a written itemized statement at all, merely telling the tenant by phone that $400 had been deducted for “cleaning.” Forty days later, the tenant had still not received written documentation. Missouri law is clear: the itemized statement must be sent by first-class mail within 30 days. This failure to itemize and mail the statement gives the tenant grounds to sue for 2x the entire deposit amount—a powerful lever, especially for a $1,500 deposit.

Common Mistakes Missouri Tenants Make

Failing to provide a forwarding address in writing. Many tenants assume their landlord will find them, but Missouri law requires the tenant to provide the address in writing. Without a forwarding address, the landlord may delay the return indefinitely, claiming they couldn’t locate you. Send your address via certified mail or email and keep proof.

Not challenging vague deduction claims immediately. If your itemized statement arrives with undefined charges like “repairs” or “restoration” without specific amounts or receipts, respond within 10 days with a written objection citing the lack of detail. Missouri courts expect detailed itemization, and a vague claim is a weak claim.

Accepting the “30-day limit” without counting carefully. The 30-day deadline begins on the day the lease terminates, not the day you vacate or the day you provide your address. Mark this date clearly on your calendar and calculate day 30 precisely. If day 30 falls on a weekend, Missouri typically allows mailing by the next business day.
