How Long Can a Residential Lease Be in Missouri?

Depending on circumstances, in Missouri it’s usually possible to have a lease of any length of time, as long as the length of the lease term is specific and agreed in writing by the landlord and tenant. Oral leases can almost never be for a term of more than one year.

Is a Contract to Lease Binding in Missouri?

Yes, a contract to lease is legally binding in Missouri. To be valid, a contract to lease may have to be written, especially for a fixed term over one year. Oral leases may be valid in some cases (especially when both parties later behave as though there’s an enforceable oral lease), but often have strict limitations on enforceability for things like length of the lease term.

Do Lease Agreements Need to Be Notarized in Missouri?

No, lease agreements do not need to be notarized in Missouri. A notary helps establish the identity of the people signing the lease, if there’s a claim of fraud, but a notary isn’t necessary for a lease to be valid.

Can a Lease Automatically Renew in Missouri?

Yes, a lease can automatically renew in Missouri, if renewal language is specifically put into the written lease. Without such language, Missouri courts will typically look at continued tenancy as a type of month-to-month rental agreement, with the same basic terms and conditions otherwise as the original lease.

Missouri Lease Agreement (Free) | 2025 Official

A Missouri residential lease agreement (“rental agreement”) is a legal contract between a landlord overseeing a residential property and a tenant who wishes to rent it. A residential lease may, on or before move-in, additionally require a security deposit from the tenant as assurance against future property damage.

Missouri Residential Lease Agreement Disclosures

These disclosures are required for residential lease agreements in Missouri:

Disclosure	Applicable To
Landlord’s Name and Address	All Units
Meth	All Units with Knowledge of Contamination
Lead Paint	All Units Built Prior to 1978

Landlord’s Name and Address

Applicable to all Missouri rentals.

Missouri leases must contain the name and address of the landlord or authorized agent. This enables smooth communication of any important legal notice. This contact information is most often written in the lease agreement, for maximum convenience. The landlord has an obligation to notify the tenant in the event of a change in contact information.

Methamphetamine Contamination Disclosure

Applicable to any Missouri rental with known possible methamphetamine contamination.

Missouri landlords must disclose any knowledge of methamphetamine production, use, or storage on the rental property. Only actual information counts, not mere suspicion. Disclosure is required regardless of who was arrested or involved.

Lead-Based Paint Disclosure

Applicable to any Missouri rentals built before 1978.

For any property built before 1978, federal law requires that a Missouri residential lease must contain a lead-based paint disclosure. This requires landlords to do the following:

Fill out and attach this lead-based paint disclosure form to the lease agreement.
Provide the tenant with an Environmental Protection Agency (EPA) approved pamphlet about the dangers of lead-based paint.
Provide any additional records or reports about the presence or hazards of lead-based paint in the unit. For multi-unit buildings with common areas, this includes information from building-wide evaluations.

Optional Disclosures and Addenda (Recommended)

The following lease agreement disclosures and addenda are not required by Missouri law in residential lease agreements, but assist with tenant management and help limit landlord liability.

Optional Disclosure	Purpose
Asbestos	Informs tenants about any asbestos hazards related to the property. Tenants can take precautions to reduce asbestos hazards by avoiding any disturbance of asbestos fibers.
Bed Bugs	Informs tenants whether the property or an adjacent unit has a history of suspected bed bug infestation, and reminds the tenant of the obligation to report suspected infestation immediately.
Late/Returned Check Fees	Specifies late fees or returned check fees related to the lease. Missouri caps late fees at $20 or 20% of the monthly rent (or whichever is greater), and caps returned check fees per check at $25, plus any actual fees charged by the depositing institution.
Medical Marijuana Use	Informs tenants about policy related to medical marijuana use on the rental property. Some state laws allow landlords to restrict marijuana usage to non-smoking methods only, or allow use only in designated smoking areas.
Mold Disclosure	Informs tenants about actual or suspected mold contamination on the property, along with any remediation efforts, to help limit landlord liability.
Move-In Checklist	Takes inventory of existing property damage, when the tenant takes possession of the rental property. This enables accurate deductions from the security deposit upon move-out.
Non-Refundable Fees	Charges not agreed by the tenant in the lease may be refundable upon lease termination. For Missouri landlords to charge a non-refundable fee, it must be disclosed and agreed as such in the lease.
Shared Utilities Arrangements	Discloses how charges are billed to individual tenants, when multiple rental units share a utility meter for the whole building or property. This ensures tenants receive fair charges and understand what uses contribute to their bill.
Smoking	Informs tenants of designated smoking areas that do not interfere with the quiet enjoyment of other tenants.

note

Some Missouri cities, like Kansas City, have more comprehensive rules than the statewide standard. Always check local laws.

Consequences of Not Including Mandatory Disclosures

Mandatory disclosures outline important health, safety, and property information for both landlord and tenant safety. A landlord who fails to provide federally or state-mandated disclosures could face legal consequences or monetary penalties, either from a tenant lawsuit or from state officials. Many lease provisions may be unenforceable without legally required disclosures.

Failure to comply with the federal lead-based paint hazard disclosure risks fines of tens of thousands of dollars per violation.
