Missouri Security Deposit Laws: Limits, Return Deadlines, and Deductions

Missouri security deposit laws provide clear guidelines for both the amount a landlord can collect and the timeline for returning it. Failure to adhere to the strict 30-day return window can result in significant financial penalties for the landlord.

Maximum Security Deposit Limit

Under Missouri law (Mo. Rev. Stat. § 535.300), a landlord may not demand or receive a security deposit in an amount that exceeds two months' rent.

Pet Deposits and Additional Fees

• Pet Deposits: Landlords can charge a pet deposit, but the total sum of the standard security deposit plus the pet deposit cannot exceed the two-month rent maximum.
• Non-Refundable Fees: Missouri law allows landlords to charge non-refundable fees (e.g., a non-refundable pet fee or cleaning fee) if explicitly stated in the lease. These fees must be clearly distinguished from a "deposit," as deposits are inherently refundable under state law.

Holding the Security Deposit

Unlike some states, Missouri has relatively few requirements for how the deposit must be stored:

• Landlords are not required to keep the deposit in a separate, interest-bearing account.
• Landlords are not required to pay the tenant any interest earned on the security deposit.
• The funds must be held in a trust-like manner, meaning the landlord holds them for the tenant unless they are rightfully claimed for damages.

Allowable Deductions

A landlord may only withhold funds from the security deposit for specific, legally permissible reasons:

1. Unpaid Rent: To cover any rent the tenant failed to pay.
2. Property Damage: To repair damages caused by the tenant, their pets, or their guests that exceed "ordinary wear and tear."
3. Lease Breaches: To compensate the landlord for actual damages caused by the tenant's failure to adequately comply with the lease agreement (e.g., early termination fees, if stipulated).
4. Cleaning: To restore the rental unit to the condition it was in at the commencement of the tenancy, ordinary wear and tear excepted.

Ordinary Wear and Tear

Landlords cannot deduct for normal depreciation. Examples of normal wear and tear include:

• Faded paint from sunlight
• Gently worn carpets in high-traffic areas
• Scuff marks on walls from normal moving of furniture

The 30-Day Return Deadline

Following the termination of the tenancy (when the tenant hands over the keys and vacates), the landlord has exactly 30 days to return the security deposit.

If the landlord makes deductions, they must send the tenant within that 30-day window:

1. The remaining balance of the security deposit (if any).
2. A written, itemized list detailing exactly what was withheld and why.

If the tenant provided a forwarding address, the items must be mailed there. If no address was provided, the landlord must mail it to the tenant's last known address (often the rental property itself).

Move-Out Inspections

Missouri tenants have the right to be present during the move-out inspection to determine damages:

• The inspection must be held at a reasonable time.
• If the tenant requests to be present, the landlord must notify the tenant in writing of the date and time of the inspection.
• The inspection is typically conducted after the tenant has completely vacated the premises and surrendered the keys.

Penalties for Landlord Non-Compliance

If a landlord wrongfully withholds all or part of the security deposit, or fails to provide the itemized statement within the 30-day window, the tenant may sue.

If the court finds the landlord acted wrongfully, the tenant can recover:

• The amount wrongfully withheld.
• Damages equal to up to twice the amount wrongfully withheld (double damages).

Best Practices for Missouri Landlords

1. Document Condition Thoroughly: Always conduct a detailed move-in and move-out inspection, heavily supported by photos and videos signed by the tenant.
2. Never Exceed the Limit: Ensure your base deposit plus any pet deposits do not exceed two months' rent.
3. Be Specific with Fees: If you want a non-refundable cleaning or pet fee, explicitly label it a "Fee" in the lease, never a "Deposit."
4. Adhere Strictly to the 30-Day Rule: Mark your calendar the day the tenant moves out. Sending the itemized list on day 31 opens you up to double-damage lawsuits.
