Missouri Security Deposit Rules: Caps, Lawful Deductions & Penalties (2026)

How much a landlord can charge, and which deductions are actually legal

At a glance

Who this covers — and who it does not

This page covers how much a landlord may charge in Missouri, and which deductions from a residential deposit are lawful. It assumes the tenancy has ended and the question is what may be withheld.

It does not cover:

How much the landlord may charge in the first place

Two months' rent (Mo. Rev. Stat. § 535.300(1)). A landlord may not demand or receive a security deposit in excess of two months' rent.

Caps frequently carry exceptions — smaller landlords, furnished units, or pets are treated differently in most states. Read the provision itself rather than relying on the headline figure.

Which deductions the statute permits

Claimed deductionPermitted in Missouri
Amounts reasonably necessary to remedy a tenant's default in payment of rentPermitted, if substantiated
Amounts reasonably necessary to restore the dwelling unit to its condition at the start of the tenancy, ordinary wear and tear exceptedPermitted, if substantiated
Carpet cleaning costs (only if the rental agreement provides for it and actual costs exceed ordinary wear)Permitted, if substantiated
Actual damages from the tenant's failure to give adequate notice to terminate (with mitigation)Permitted, if substantiated

Which deductions the statute does not permit

Claimed deductionPermitted in Missouri
Ordinary wear and tearNot permitted
Any amount withheld without a written itemized list within 30 daysNot permitted
Any amount wrongfully withheld (triggers 2x damages)Not permitted

Whether a specific charge is lawful depends on the facts — how old the damage is, whether the lease addressed it, and whether the landlord can document the cost. A charge being in the "permitted" column does not make it automatically collectable.

Who has to prove what

The landlord must furnish a written itemized list of damages within 30 days. Wrongful withholding of any portion entitles the tenant to twice the amount wrongfully withheld.

In Missouri the burden sits with the landlord. This matters strategically: if the burden is theirs, your task is to request the documentation rather than to prove the deduction wrong. Mo. Rev. Stat. § 535.300(3), (6) ↗

What you can claim if deductions are unlawful

Tools that exist in Missouri

Twice the amount wrongfully withheld

On wrongful withholding of any portion, the tenant recovers twice the amount wrongfully withheld — keyed to the withheld portion, not the full deposit.

Two months' rent cap

The deposit may not exceed two months' rent.

Statute of limitations: 10 years on a written contract

Missouri's limitations period for actions on a written contract is 10 years (Mo. Rev. Stat. § 516.110(1)) — substantially longer than the 6-year norm in most states.

Interest belongs to the landlord

Any interest earned on a Missouri security deposit belongs to the landlord, not the tenant — unlike Maryland or New Jersey, which credit interest to the tenant.

Mo. Rev. Stat. § 535.300(2) ↗

Common landlord defences and how to answer them

““I kept the deposit for damages.””

Missouri requires return of the full deposit or a written itemized list of damages plus the balance within 30 days. Without that, you have wrongfully withheld, and I am entitled to twice the amount wrongfully withheld.

Mo. Rev. Stat. § 535.300(3), (6)

““You were not there for the inspection.””

You were required to give me reasonable written notice of the inspection and I had the right to be present. Failure to provide that notice does not defeat my claim.

Mo. Rev. Stat. § 535.300(5)

““The deposit covered normal wear.””

Ordinary wear and tear is expressly excepted. You may withhold only for rent defaults or restoration beyond ordinary wear.

Mo. Rev. Stat. § 535.300(4)(2)

Where sources disagree

Some widely circulated summaries of Missouri deposit law state things the statute does not say. We list the disagreements rather than picking a side silently.

What we follow: 2x the amount wrongfully withheld

The statute says "twice the amount wrongfully withheld," keyed to the withheld portion, not the full deposit.
