Missouri landlord-tenant law is spread across two main chapters of the Revised Statutes of Missouri: Chapter 441 covers general landlord-tenant matters and tenancies, while Chapter 535 covers landlord-tenant actions and contains the state’s strict security deposit statute. Missouri courts treat RSMo § 535.300 as a consumer-protection statute, so landlords who mishandle deposits face real penalties — including double damages.
Missouri has no statewide rent control, and its habitability protections are more limited than in states with comprehensive statutes, which makes the written lease agreement even more important. Local rules also matter: Kansas City, St. Louis, and Columbia have their own tenant protections, such as source-of-income rules and, in some cases, just-cause requirements.
This guide covers the rules that generate the most disputes in Missouri: the deposit statute, allowable deductions, notice periods, repairs, and eviction. It is general information, not legal advice.
| Governing law | RSMo Chapters 441 and 535 |
|---|---|
| Security deposit cap | 2 months’ rent (RSMo § 535.300.1) |
| Deposit return deadline | 30 days after the tenancy ends: full refund or itemized list plus balance |
| Wrongful withholding penalty | Twice the amount wrongfully withheld (RSMo § 535.300.6) |
| Deposit account | Insured bank or credit union; interest belongs to the landlord |
| Move-out inspection | Written notice required; tenant may attend (RSMo § 535.300.5) |
Missouri Rental Law at a Glance
The two statutes a Missouri landlord or tenant should know are RSMo Chapter 441 (which covers tenancies, notice, and landlord remedies) and RSMo Chapter 535 (landlord-tenant actions, including evictions and the security deposit rules). Federal law adds layers such as the lead-based paint disclosure for housing built before 1978.
Missouri leases are freedom-of-contract documents: many terms that are regulated elsewhere — rent amounts, late fees, notice periods — are whatever the parties agree to in the lease. That makes the written agreement the single most important document in a Missouri tenancy, and it is why a Missouri-specific agreement beats a generic national template. Courts enforce clear, signed lease terms unless a statute or public policy overrides them.
Security Deposits: Missouri’s Strict 30-Day Rule
RSMo § 535.300 gives Missouri one of the most mechanical deposit statutes in the country. A landlord may not demand a deposit larger than two months’ rent (§ 535.300.1), and the deposit must be held in a bank, credit union, or depository institution insured by a federal agency (§ 535.300.2). Any interest the account earns belongs to the landlord.
Within 30 days after the tenancy ends, the landlord must either return the full deposit or furnish a written, itemized list of the damages for which the deposit is withheld, along with the remaining balance (§ 535.300.3). Mailing the statement and payment to the tenant’s last known address satisfies the rule. Before any withholding, the landlord must give the tenant written notice of the date and time of the move-out inspection, and the tenant has the right to be present (§ 535.300.5).
If the landlord wrongfully withholds all or part of the deposit, the tenant may recover twice the amount wrongfully withheld (§ 535.300.6). Nonrefundable security deposits are not allowed — every dollar collected as a security deposit must be refundable, less lawful deductions. Pet deposits are treated separately from security deposits, so label them clearly in the lease.
What Missouri Landlords Can Deduct
Missouri law permits deductions only for what is “reasonably necessary” for three specific purposes: unpaid rent; restoring the unit to its condition at move-in, ordinary wear and tear excepted; and actual damages from the tenant’s failure to give adequate notice to terminate — provided the landlord made reasonable efforts to mitigate those damages (§ 535.300.4).
Carpet cleaning gets special treatment: a landlord can charge for actual carpet-cleaning costs only if the lease contains a notice that the tenant may be liable for carpet-cleaning costs exceeding ordinary wear and tear, and the landlord must provide a receipt for the actual cleaning cost within 30 days. Ordinary wear and tear — minor scuffs, faded paint, worn carpet in high-traffic areas — is never deductible.
The practical rule for Missouri landlords: document the unit at move-in and move-out, send the itemization within 30 days with real receipts, and apply depreciation to older items rather than charging full replacement cost. The practical rule for tenants: give a written forwarding address, attend the inspection, and demand an itemized list before accepting any deduction.
Rent Increases and Notice Periods in Missouri
Missouri has no statutory cap on rent increases and no rent control. For a fixed-term lease, the rent is locked for the term; an increase applies only at renewal, with notice governed by the lease. For a month-to-month tenancy, Missouri generally requires notice of at least one full rental period to terminate or change terms — confirm the current text of RSMo § 441.060, which covers termination notice, before relying on a specific number.
Tenants receiving a rent increase should check the lease for the required notice period and confirm the increase is in writing. Landlords should send increases in writing, with enough notice, and keep proof of delivery — an oral rent increase on a month-to-month tenancy is a common source of avoidable disputes.
Habitability, Repairs, and Disclosures in Missouri
Missouri does not have a comprehensive statewide habitability statute like some states, but Missouri courts recognize an implied warranty of habitability, and landlords must maintain the premises in a condition that does not endanger health or safety. Repairs the landlord agrees to in the lease should be treated as binding contract terms.
Missouri tenants should be cautious about withholding rent to force repairs: Missouri law is narrower than many states, and self-help remedies such as repair-and-deduct are not broadly available. The safer path is a written notice of the problem, followed by a rent escrow or court action where permitted. Federal lead-paint disclosure applies to pre-1978 housing, and landlords must provide working smoke detectors where required by local code.
Evictions in Missouri
Evictions in Missouri proceed through the unlawful detainer process under Chapter 535, filed in the county where the property sits. For nonpayment of rent, a landlord typically gives a written notice to quit — commonly 10 days — before filing suit (verify the current text of RSMo § 535.060). Holdover tenancies and lease violations follow the notice periods in the lease or statute.
A tenant served with an eviction summons should respond in writing within the court deadline — in Missouri, an answer filed in time stops a default judgment. Tenants facing eviction should contact Legal Services of Eastern Missouri, Mid-Missouri Legal Services, or a local tenant organization right away. Landlords cannot use self-help: changing locks, removing belongings, or shutting off utilities is illegal in Missouri.
Resolving Disputes: Small Claims and Beyond
Most Missouri deposit disputes end up in small claims court, where the jurisdictional limit is $5,000 — enough to cover the deposit and the double-damages penalty in most cases. Tenants should start with a written demand letter citing § 535.300, give the landlord a deadline, and file only if the landlord does not respond.
Missouri courts have held that the double-damages remedy in § 535.300 applies to residential tenancies; commercial tenants cannot use it. Whether you are a landlord or a tenant, the case is decided on documents: the lease, move-in and move-out condition records, the written notice of inspection, the itemized statement, and proof of mailing. Keep copies of everything.
