Missouri Landlord-Tenant Laws (2026): Deposits, Notice, and Tenant Rights

Missouri landlords may collect a security deposit of up to two months' rent and must return it within 30 days of move-out. There is no fixed statute requiring advance notice before entry, so landlords must give reasonable notice in practice.

Security deposits in Missouri

Missouri limits security deposits to two months' rent under RSMo 535.300. After a tenancy ends, a landlord has 30 days to either return the full deposit or provide a written itemized statement of deductions along with any remaining balance. If the landlord misses the deadline or fails to give a written itemization, the tenant may be entitled to double the withheld amount in a court action.

Allowable deductions include unpaid rent, damage beyond normal wear and tear, and any other lease-authorized charges. Missouri does not require landlords to pay interest on security deposits.

When can a landlord enter? Notice rules

Missouri has no statute that sets a fixed number of hours a landlord must give before entering a rental unit. Courts apply a reasonableness standard, which in practice means a landlord should give at least 24 hours' notice except in genuine emergencies such as a fire, burst pipe, or other immediate threat to the property or occupants.

For non-emergency maintenance, inspections, or showing the unit to prospective tenants or buyers, written or verbal notice a day or two in advance is the accepted practice. Entry should occur during normal business hours unless the tenant agrees otherwise. A landlord who repeatedly enters without any notice may be liable for breach of the covenant of quiet enjoyment.

Ending a lease: notice to vacate

To terminate a month-to-month tenancy in Missouri, either the landlord or the tenant must give at least one full month's written notice before the end of a rental period. A notice given on, say, June 15 would typically end the tenancy on July 31 (the end of the next complete rental period).

Fixed-term leases end automatically on the lease expiration date unless the parties renew or the landlord accepts rent and the tenancy converts to month-to-month. For nonpayment of rent or a lease violation, the landlord must follow a separate legal process. See the Missouri eviction notice page for the required notice periods and forms in those situations.

Repairs and the warranty of habitability

Missouri courts recognize an implied warranty of habitability, meaning landlords must maintain rental units in a condition fit for human habitation: working heat, plumbing, structural safety, and freedom from rodents or other conditions that endanger health.

If a landlord fails to make a necessary repair, Missouri offers repair-and-deduct as a tenant remedy under RSMo 441.234, but only under specific conditions: the tenant must have lived in the unit for at least six months, must give the landlord written notice and a 14-day opportunity to fix the problem, and the repair cost must not exceed $300 or half a month's rent, whichever is less. The repair-and-deduct remedy covers violations of local housing codes, not merely personal preferences; if a condition violates a municipal or county housing ordinance, that strengthens the tenant's written notice. The landlord's 14-day clock runs from the date of actual receipt of the written notice, so delivering it by certified mail or in person with a dated receipt is important for establishing the timeline. If the repair cost is higher than the $300 or half-month cap, or if the tenant has lived there fewer than six months, the available remedies are seeking a court order, requesting rent escrow, or (where the landlord's failure destroys substantially all of the unit's value) treating the lease as constructively terminated. Tenants should document all repair requests in writing and keep copies.

Rent, late fees, and rent control

Missouri has no statutory cap or "safe harbor" figure for residential late fees. RSMo Chapter 535 (security deposits) and Chapter 441 (landlord-tenant) do not set a dollar amount or percentage benchmark for late charges. A late fee is enforceable if it is clearly stated in the lease and not so disproportionate to actual harm that a court would treat it as an unenforceable penalty under general contract law.

Missouri is a rent-control preemption state. Under RSMo 441.043, no city or county may enact an ordinance that controls rents or fees landlords charge. There is no statewide rent increase limit either, so landlords may raise rent by any amount with proper advance notice (typically at least 30 days for a month-to-month tenancy). Tenants in Missouri have no statutory protection against large rent increases during a periodic tenancy, though any increase during a fixed-term lease requires agreement from both parties.

There is also no required grace period for rent payment under Missouri law, though many leases include one. Tenants should review their lease carefully.

If you have a landlord-tenant dispute in Missouri

The most important step is to document everything in writing. Send all repair requests, complaints, and notices by certified mail or email so you have a timestamp and a paper trail. If a landlord refuses to return your deposit without justification, you can file in Missouri small claims court for amounts up to $5,000; the 30-day deadline is the key date to anchor your claim.

For housing code violations, contact your local city or county housing inspector. The Missouri Attorney General's consumer protection office handles unfair business practices and can be a resource for serious landlord misconduct. Missouri Legal Aid organizations offer free or reduced-cost help to qualifying low-income tenants. If the dispute involves a habitability issue that affects health and safety, a tenant should also consider consulting a licensed attorney before withholding or escrowing rent, since doing so incorrectly can give the landlord grounds for eviction.

This article is general legal information, not legal advice. Landlord-tenant rules vary by state and city and change, and some cities add their own ordinances. For advice about a specific situation, consult a licensed attorney or your state housing agency.
