Missouri Landlord-Tenant Law: A Rental Property Management Guide for St. Louis Owners

Missouri Security Deposit Rules Every St. Louis Landlord Must Follow

Missouri law places clear limits on security deposits. Under Missouri Revised Statutes Section 535.300, landlords cannot charge more than two months' rent as a security deposit, including pet deposits.

When a tenant moves out, deposits must be returned within 30 days with an itemized list of deductions if applicable. Wrongfully withholding a deposit can result in double damages.

• Additional deposit rules worth knowing:
• Deposits must be held in a separate escrow or bank account, not a personal account.
• Missouri does not allow nonrefundable deposits or fees; all deposits must be fully or partially refundable at lease end.
• Landlords may only deduct for damage beyond normal wear and tear.

Deposit management is one reason many owners seek rental property management in St. Louis MO: a professional team tracks deadlines, documents conditions, and handles itemized statements.

Notice Requirements and Lease Termination in Missouri

Proper written notice is required before ending a tenancy or filing for eviction. Missouri Revised Statutes Section 441.060 requires one month's written notice to end a month-to-month tenancy, with the tenancy ending on a periodic rent-paying date not less than one month after the tenant receives notice.

Fixed-term leases end automatically on the expiration date unless renewed or the landlord accepts rent, converting the tenancy to month-to-month.

St. Louis Occupancy Permits: A Local Layer Landlords Cannot Ignore

St. Louis area municipalities often require an occupancy permit before a new tenant moves in. The purpose is for the city to verify the landlord has obtained a passed inspection prior to occupancy.

Requirements vary by municipality. Cities like Bridgeton, Breckenridge Hills, Florissant, and Hazelwood each operate under their own rules, so the process in one neighborhood may differ from one just a few miles away. Always contact the appropriate municipality directly to verify current requirements, fees, and procedures. Working with a team experienced in rental property management in St. Louis MO can save significant time, since they already know the permit landscape across the region.

Habitability Standards Missouri Landlords Are Required to Meet

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 conditions that endanger health.

Repairs must be made within a reasonable time after notice, generally 14 days for most code issues. If repairs are ignored, tenants can repair and deduct, sue for costs, or pay rent into a court escrow account.

Key obligations include:

• Providing working heat, electricity, and plumbing at all times.
• Following all applicable building, health, and safety codes.
• Refraining from shutting off utilities or changing locks to force a tenant out; such actions are illegal without a court order.

Overview of the Missouri Eviction Process

Missouri eviction law follows a structured process. The landlord must serve notice, file a lawsuit, appear at a hearing, obtain a judgment, and then request removal by the sheriff if needed.

The notice type depends on the reason for eviction:

• A 5-Day Notice to Pay Rent or Quit is used when tenants fail to pay rent.
• A 10-Day Notice to Cure or Quit is used for lease violations such as unauthorized pets or property damage.
• An Unconditional Notice to Quit is used for illegal activity or significant property destruction.
• A 30-Day Notice to Terminate Tenancy is used to end a month-to-month tenancy for any lawful reason.

 Self-help eviction tactics such as changing locks or cutting utilities are illegal in Missouri.

What Happens If I Do Not Return a Security Deposit on Time?

If a landlord wrongfully withholds a deposit, the tenant may recover up to twice the amount withheld. Always return the deposit with an itemized statement within 30 days of move-out.

Do I Need an Occupancy Permit for Every Tenant Change in St. Louis?

Rules vary by municipality. Always confirm requirements with your specific city hall before a new tenant moves in, as some cities require inspections at every occupant change while others do not.

Can I Raise Rent Whenever I Want in Missouri?

Missouri has no statewide rent control laws and expressly preempts local rent control ordinances. Landlords can set and increase rent without statutory limits but must provide proper notice for month-to-month tenancies and cannot raise rent during a fixed-term lease unless the lease allows it.

Can I Evict a Tenant Without Going to Court in Missouri?

No. Landlords must follow a sequence of notices, filings, hearings, and court orders to legally remove a tenant. Self-help eviction tactics are illegal.
