Missouri Rent Increase Rules at a Glance

Statewide rent cap NO. Missouri has no statewide rent cap. There is no limit on how much a landlord can raise rent. Landlords may increase rent by any amount as long as the increase is not discriminatory under the Fair Housing Act and is not retaliatory. A pending bill (the Missouri Housing Predictability and Transparency Act, HB 2996) would cap increases at 7% plus CPI or 10%, whichever is less, starting January 1, 2027 — but as of June 2026 this bill has not been enacted into law.
Notice required before increase Missouri has no statute dedicated specifically to rent increase notice. Instead, the general lease termination notice rules under RSMo 441.060 apply. For month-to-month tenancies, a landlord must give at least 30 days (one full rental period) written notice before a rent increase takes effect. For fixed-term leases (e.g. 12-month), the landlord cannot raise rent until the lease expires and must provide notice before renewal — typically 30 to 60 days before the lease end date, depending on the lease terms. For manufactured (mobile) home parks, RSMo 700.600 requires at least 60 days written notice before any rent increase, except increases based solely on property tax increases.
How often rent can be raised No statutory limit. Missouri law does not restrict how often a landlord can raise rent. For month-to-month tenancies, a landlord could theoretically raise rent every month as long as proper 30-day written notice is given each time. For fixed-term leases, the landlord can raise rent at each lease renewal. There is no once-per-year rule in Missouri law.
During a fixed-term lease No. A Missouri landlord generally cannot raise rent during a fixed-term lease unless the lease itself contains a clause explicitly allowing mid-lease rent adjustments. If the lease is silent on rent increases, the rent remains fixed for the entire lease term. Any increase without a lease provision authorizing it would be a breach of the lease agreement, and the tenant is not obligated to pay the higher amount.

Retaliatory increases: Missouri provides limited protection against retaliatory rent increases compared to many other states. If a tenant reports health or safety code violations to a government agency, complains in writing to the landlord about needed repairs, or joins a tenant organization, the landlord is prohibited from retaliating with a rent increase, service reduction, or eviction.

However, Missouri’s retaliatory conduct protections are weaker than most states. Retaliation is difficult to prove and may not be raised as a defense in many eviction proceedings. There is no specific statutory presumption period (like 6 or 12 months) during which a rent increase is automatically presumed retaliatory after a tenant complaint.

Missouri Cities With Local Rent Control

Effectively none. Missouri state law (RSMo 441.043) expressly prohibits any city or county from enacting, maintaining, or enforcing any ordinance that regulates the amount of rent charged for privately owned residential or commercial rental property. Some sources reference a Columbia, Missouri rent stabilization ordinance from 2021, but RSMo 441.043 preempts local rent control for private housing.

Any local ordinance that caps rent on private property would conflict with this state preemption and may not be enforceable. The only exceptions allowed under RSMo 441.043 are: (1) government-owned property, (2) voluntary agreements for subsidized rental properties, and (3) properties assisted with Community Development Block Grant (CDBG) funds.

Exempt properties: Not applicable. Because Missouri has no rent cap or rent control, there are no exemptions — all private rental properties are unregulated with respect to the amount of rent a landlord can charge.

State preemption: YES. Missouri has strong rent control preemption. RSMo 441.043 explicitly prohibits any county or city — including those with charter forms of government — from enacting, maintaining, or enforcing any ordinance or resolution that regulates the amount of rent charged for privately owned residential or commercial property.

This was further reinforced by HB 595 (signed July 14, 2025, effective August 28, 2025), which additionally prohibits local governments from restricting landlord tenant-screening practices, limiting security deposit amounts, or requiring right of first refusal for tenants.

Missouri is one of the most restrictive states in the country for local tenant protection ordinances.

What to Do If Your Rent Increase Is Illegal

If you believe a rent increase is illegal in Missouri — for example, if it violates the Fair Housing Act, is retaliatory after you reported code violations, or was imposed mid-lease without a lease provision allowing it — you may be able to take several steps. (1) Document everything: keep copies of your lease, all rent increase notices, and any communications with your landlord.

(2) File a complaint with the Missouri Attorney General’s Consumer Protection Division at ago.mo.gov or call their office. (3) File a Fair Housing complaint with the Missouri Commission on Human Rights (MCHR) or with HUD if you believe the increase is discriminatory based on race, color, religion, sex, national origin, familial status, or disability.

(4) Consult a tenant rights attorney or contact Missouri Legal Aid (lsmo.org) for free legal help if you qualify. (5) If you are in a mobile home park, contact the AG’s office about violations of RSMo 700.600 notice requirements.

(6) You may be able to withhold the increased portion of rent if the increase violates your lease, but check with an attorney first — Missouri is not a tenant-friendly state for rent withholding.

Other Missouri rent rules: Missouri has several unique rules tenants should know. (1) Mobile home park tenants have stronger protections than standard renters: RSMo 700.600 requires 60 days written notice for rent increases and 120 days notice if the park is closing or changing use, and the landlord cannot raise rent during the 60-day period before or after giving a closure notice (except for property tax pass-throughs).

The full mobile home statute is at https://revisor.mo.gov/main/OneSection.aspx?section=700.600. (2) Missouri has no implied warranty of habitability established by state statute for most rental housing — tenants in many jurisdictions rely on local housing codes instead.

(3) HB 595 (effective August 28, 2025) is one of the broadest landlord preemption laws in the country, preventing cities from enacting source-of-income discrimination protections, security deposit caps, or tenant right-of-first-refusal ordinances. (4) Missouri does not require landlords to provide a reason for non-renewal of a lease or for a rent increase, as long as the increase is not discriminatory or retaliatory.

(5) The RSMo 441.043 preemption statute has narrow exceptions allowing rent regulation only for government-owned property, voluntary subsidized housing agreements, and CDBG-funded properties.

Understanding Missouri Rent Increase Laws

Whether a Missouri rent increase is legal depends on the cap (if any), the notice given, and whether the increase is retaliatory. Missouri rent increase laws protect tenants from surprise hikes by requiring a minimum notice period before any increase takes effect.

If you believe a Missouri rent increase violates these rules, document the notice you received, check the math against the cap, and contact your local housing authority or legal-aid office.

Knowing the Missouri rent increase rules before your lease renews puts you in a much stronger position.
