Missouri Rent Increase Laws: The Landlord and Tenant Guide
No Rent Cap · Local Control Barred · One Month’s Notice · Mid-Lease Limits · Retaliation · Fair Housing
Missouri is a free-market rent state. Unlike California or New York, it has no rent cap and no statewide rent control, and Missouri Revised Statutes section 441.043 goes a step further and bars every county and city from adopting a rent-control ordinance of its own. So the dollar amount of an increase is largely up to the landlord. What the law does regulate is the process: the written notice a month-to-month increase requires under section 441.060, the rule that a fixed-term lease locks the rent until it ends, a narrow set of retaliation protections, and the fair-housing limits that apply to every landlord. Get the process right and your increase holds; miss the notice or the timing and the old rent simply continues.
The stakes are practical. Missouri does not cap the number, but an increase served with too little notice does not take effect, a mid-term increase with no lease clause is unenforceable, and an increase aimed at a protected class is unlawful no matter how small it is. Because a subsidized-housing program, a specific lease term, or a local ordinance can add rules the state statute does not, treat every figure and timeline in this guide as a starting point and verify the current law for your property and program before you serve anything.
Below, a detailed overview video summarizes the Missouri framework; the sections that follow break down each piece — the no-cap rule and the section 441.043 preemption, the one month’s written notice under section 441.060, when you may raise rent at all, why a fixed lease locks the rent, Missouri’s limited retaliation protection, fair housing under the federal act and the Missouri Human Rights Act, documentation, and a step-by-step landlord playbook — plus a Missouri-specific FAQ.

No Cap and No Rent Control in Missouri
The defining feature of Missouri rent-increase law is what it does not contain: there is no statewide rent control and no ceiling on the amount of an increase. A landlord may set and raise the rent to whatever the market will bear, subject to the process rules that follow. This is the opposite of a capped state, where a formula limits the annual increase; in Missouri, the constraint is timing, form, and motive, not the dollar figure.
Section 441.043 Bars Local Rent Control
Missouri does not merely decline to impose rent control at the state level — it forbids local governments from creating their own. Under Missouri Revised Statutes section 441.043, no county or city, including a county or city with a charter form of government, may enact, maintain, or enforce any ordinance or resolution that regulates the amount of rent to be charged for privately owned single-family or multiple-unit residential or commercial rental property. In plain terms, a Missouri city cannot pass a rent-stabilization ordinance the way Los Angeles or New York City can. The statute carries a narrow exception for property the government itself owns and for certain projects using federal community-development-block-grant funds, but for ordinary private rentals the preemption is complete.
What “no cap” does not mean
The absence of a cap removes the ceiling on the amount, not the rest of the law. A Missouri rent increase still has to follow the written-notice rule, wait for the right point in the tenancy, and stay clear of discrimination. Landlords sometimes read “no rent control” as “no rules,” which is where trouble starts. The amount is free; the process is not.
A subsidized unit can still be capped by its program
Section 441.043 is about state and local law. It does not touch the contractual and regulatory limits that ride with a housing subsidy. A unit in the Housing Choice Voucher program, a Low-Income Housing Tax Credit property, or another assisted program is subject to that program’s rent-increase rules and approvals, which can cap the amount and require advance sign-off regardless of the general no-cap rule. If the unit is subsidized, check the program terms first.
Takeaway
Missouri has no rent cap and no rent control, and section 441.043 bars every county and city from adopting its own. The amount of an increase is set by the market, not a statute — but the notice, timing, and anti-discrimination rules still apply, and a subsidized unit follows its program’s limits.
Notice: One Month, in Writing
Missouri has no rent-increase-specific notice statute the way capped states do. Instead, a rent increase on a month-to-month tenancy runs through the general termination-and-new-terms mechanism in Missouri Revised Statutes section 441.060. That section lets either the landlord or the tenant end a month-to-month tenancy by written notice, and a landlord raises the rent by giving that same written notice of the new terms — effectively ending the old rent arrangement and offering the tenancy on the new rent going forward.
| Tenancy type | Notice to raise rent | When the new rent begins |
|---|---|---|
| Month-to-month | At least one month’s written notice under section 441.060 | On a periodic rent-paying date at least one month after the tenant receives the notice |
| Fixed-term lease | No increase during the term unless the lease allows it | At renewal, when a new term begins |
Under section 441.060, the notice must be in writing and must state that the tenancy shall terminate upon a periodic rent-paying date not less than one month after the notice is received. For a rent increase, the practical reading is that the landlord gives at least one full month’s written notice, tied to a rent-paying date, before the new rent takes effect. Counting matters: the month runs to the next rent-paying date, so a notice that lands mid-cycle generally takes effect on the following period, not partway through one. Because Missouri’s periodic-tenancy notice is anchored to the rent-paying date rather than a flat count of calendar days, give yourself margin and serve the notice well before the intended effective date.
What a Proper Notice Contains and How to Serve It
A defensible Missouri rent-increase notice is in writing and states, at minimum, the tenant’s name and the property address, the current rent, the new rent, and the exact date the new rent takes effect — a rent-paying date at least a full month out. A verbal announcement, a text message, or an email the tenant never agreed to accept as a delivery method does not properly start the clock, and until a proper written notice is given, the old rent continues. Serve it by a provable method — certified mail with return receipt, personal delivery with a signed acknowledgment, or another method your lease allows — and keep a copy of both the notice and the proof of delivery.
Longer periods can override the minimum
Section 441.060 sets a floor, not a ceiling. If a lease, a subsidized-housing program, a recorded regulatory agreement, or a federal rule requires a longer notice period than one month, the longer period controls. Some landlords adopt a longer notice by practice — sixty days is common for annual renewals — to give the tenant time to decide and to reduce turnover disputes. A special rule also applies to certain mobile-home lot tenancies under section 441.060, where a longer notice can be required; confirm the exact rule if the unit is a manufactured or mobile home on leased land.
Takeaway
To raise rent on a month-to-month tenancy, give at least one month’s written notice under section 441.060, tied to a rent-paying date, stating the current rent, the new rent, and the effective date. Serve it by a provable method and keep proof — until a proper written notice is given, the old rent continues.
When You Can Raise the Rent at All
The notice rule only matters once you actually have the right to raise the rent. In Missouri, as everywhere, that right depends on the tenancy.
During a Fixed-Term Lease: Generally Locked
While a fixed-term lease is running, the rent is set at the agreed amount for the whole term. You cannot raise it mid-term unless the written lease itself contains an explicit escalation clause that permits the change. Absent that clause, the tenant is entitled to the agreed rent through the end of the term, and a “notice” purporting to raise it early does not bind the tenant. Missouri’s no-cap rule does not change this — a free-market amount still cannot be imposed in the middle of a term the lease fixed.
At Renewal or on a Month-to-Month Tenancy
The two ordinary windows to raise rent are at lease renewal, when a new term begins and both sides agree to new terms, and during a month-to-month tenancy, where a landlord may change the rent going forward by serving the proper section 441.060 notice. On a month-to-month, the increase takes effect only after the one month’s notice runs to the next rent-paying date; the tenant can accept the new rent and stay, or give the tenant’s own one month’s notice and move out.
A mid-term increase without authority is void
Trying to raise rent partway through a fixed-term lease with no escalation clause does not fail quietly — the increase is unenforceable, and a tenant who keeps paying the original rent is in the right. Do not treat a tenant’s silence, or a single overpayment, as agreement to a new rent. Wait for renewal, or move the tenancy to a lawful month-to-month process, before adjusting the number.
Takeaway
You may raise rent at renewal or on a month-to-month tenancy with proper notice, but never mid-term on a fixed lease unless the lease expressly allows it. The tenancy type decides whether you even have the authority; section 441.060 decides how.
Retaliation: Missouri’s Protection Is Limited
This is the area where Missouri differs most from tenant-protective states, and it is easy to overstate, so be precise. Many states have a broad statute that presumes a rent increase soon after a tenant complaint is retaliatory and shifts the burden to the landlord. Missouri has no such general statewide statute for rent increases. The Chapter 441 sections sometimes cited in this context — sections 441.870 and 441.880 — deal with eviction immunity and the stay of an eviction execution, not with retaliatory rent increases, so they do not supply a broad rent-increase retaliation defense.
Where Protection Can Still Exist
That the state statute is narrow does not mean anything goes. Protection against a retaliatory increase can arise from several other sources: a subsidized-housing program rule that forbids retaliation as a condition of participation; a lease term the landlord agreed to; common-law or equitable defenses a court may recognize on the facts; and, importantly, a local ordinance. Kansas City, for example, prohibits a landlord from raising the rent because a tenant complained to the landlord or an agency about a health or safety condition of the property. Because coverage depends on the program and the locality, confirm the rule that actually applies to your unit rather than assuming Missouri either forbids or permits retaliatory increases across the board.
Do not overstate — or ignore — the retaliation rule
It would be wrong to tell a Missouri tenant that a statewide statute automatically voids a rent increase that follows a complaint; in most of the state, no such statute exists. It would be equally wrong to assume a landlord may freely punish a complaint; a program rule or a city ordinance may forbid exactly that, and courts do not favor transparent reprisals. The honest answer is that Missouri’s rent-increase retaliation protection is limited and fact-specific — verify the program and local rule for the property.
Why timing still matters even without a broad statute
Regardless of whether a statute applies, an increase served days after a tenant reports a code violation or requests a repair invites a dispute, a bad-faith argument, and a hard-to-defend optics problem. The safest practice is the same one capped states require by law: time increases to the ordinary schedule — renewal or an annual anniversary — and document the market or cost reason behind the number, so the increase reads as routine rather than as reprisal.
Takeaway
Missouri’s statutory retaliation protection for rent increases is limited — there is no broad statewide statute, and sections 441.870 and 441.880 address eviction matters, not retaliatory increases. Protection can still come from a subsidized-housing rule, a lease term, common-law defenses, or a local ordinance such as Kansas City’s. Verify the rule for the unit, and never time an increase to a complaint.
Fair Housing Limits on a Missouri Increase
Even with no cap and a narrow retaliation rule, one limit applies to every Missouri landlord: a rent increase cannot be a vehicle for housing discrimination. An increase that clears the notice and timing rules is still unlawful if its motive is discriminatory.
The Federal Fair Housing Act and the Missouri Human Rights Act
Two laws work together. The federal Fair Housing Act prohibits discrimination in the terms or conditions of a rental — which includes a selectively applied rent increase — because of race, color, religion, national origin, sex, familial status, or disability. The Missouri Human Rights Act, at Missouri Revised Statutes section 213.040, makes it an unlawful housing practice to discriminate in the terms, conditions, or privileges of a rental because of race, color, religion, national origin, ancestry, sex, disability, or familial status. Raising one tenant’s rent more steeply, or on a different schedule, because of a protected characteristic is discrimination under both laws, no matter how small the dollar amount.
No statewide source-of-income protection in Missouri
Unlike California and several other states, Missouri does not add source of income to its protected classes. Neither the Missouri Human Rights Act nor the federal Fair Housing Act requires a landlord to accept a Section 8 Housing Choice Voucher on that basis alone, so a statewide voucher-based claim generally does not exist. A city or county could adopt its own source-of-income ordinance, however, so confirm the local rule for the property before assuming there is no such protection. And once a landlord does accept a voucher, the subsidized-housing program’s own rent and increase rules then apply to that unit.
Consistency is your best defense
Increases applied evenly across comparable units on a regular schedule are far easier to defend than a one-off increase aimed at a single tenant. A selectively applied hike invites a fair-housing claim even when Missouri sets no cap on the amount — because the claim is about why this tenant was singled out, not about how large the number is. Set the increase by an objective, even-handed method — market rate, a fixed schedule, or a documented cost basis — and apply it the same way to comparable units.
Takeaway
A no-cap increase is still unlawful if it is discriminatory under the federal Fair Housing Act or the Missouri Human Rights Act (section 213.040): race, color, religion, national origin, ancestry, sex, disability, familial status. Missouri adds no statewide source-of-income protection. Apply increases consistently, on schedule, by a documented method.
Screening Before You Reset the Rent
A rent increase is also a moment to think about who is in the unit. When a tenant declines an increase and moves on — which, in a no-cap state, can happen at the market’s edge — the next applicant should be screened to the same standard you use for everyone. Consistency here is not just good practice; the federal Fair Credit Reporting Act governs that report whether you are in Missouri or anywhere else.
Get written consent, pull a consumer report for a permissible purpose, apply the same objective criteria you apply to every applicant, and send an adverse-action notice if the report drives a denial. The same discipline that makes a rent increase defensible — objective criteria, applied uniformly, documented — makes the screening behind the next tenancy defensible too. For the Missouri-specific rules on what you can check and how, see our guide to Missouri tenant screening laws.
Takeaway
When an increase turns a unit over, screen the next applicant to the same objective, documented standard under the Fair Credit Reporting Act — written consent, a permissible-purpose report, uniform criteria, and an adverse-action notice on a denial. Consistent screening protects the next tenancy the way a consistent increase method protects the last one.
The Missouri Landlord Playbook
Put the whole framework into a repeatable sequence and a rent increase becomes routine instead of risky. Follow these steps every time.
Confirm the tenancy type and the point in the term
Determine whether the tenancy is month-to-month or a fixed term. A fixed-term lease locks the rent until it ends unless it contains an escalation clause; a month-to-month can be raised with proper notice.
Check for program or local rules
If the unit is subsidized or sits in a city with its own tenant ordinance, confirm any rent-increase approval, cap, or retaliation rule that program or locality adds. The state no-cap rule does not override a program limit.
Set the new rent by an objective method
Choose the number from market comparables, a fixed schedule, or a documented cost basis, and apply the same method to comparable units so the increase is even-handed and defensible.
Serve at least one month’s written notice
Under section 441.060, give at least one month’s written notice tied to a rent-paying date, stating the current rent, the new rent, and the effective date. Give more time if a lease or program requires it.
Clear the timing of any complaint
Make sure the increase is not landing right after a tenant complaint or repair request. Even where no statute applies, an increase that reads as reprisal invites a dispute.
Document everything
Keep a copy of the notice, the proof of delivery, and a note of the market or cost basis behind the number. Consistent, documented increases are the ones that hold up.
Need the notice itself?
A ready-to-fill notice keeps the required fields in place. See our free Missouri rent increase notice form, and the Missouri lease agreement form if you need an escalation clause or a fresh renewal term. Always tailor the numbers to your unit and verify current law.
Common Scenarios, Quickly Answered
✓ Usually Defensible
- Month-to-month raise with proper notice. A written notice of at least one month, tied to a rent-paying date, stating the new rent and effective date.
- Renewal increase. A raise announced well ahead of a fixed-term renewal, with sixty days a common practice for annual leases.
- Market reset at turnover. Setting a new market rent for a new tenant after the prior one moves out — no cap constrains the starting rent.
- Consistent annual adjustment. The same method and schedule applied across comparable units, with documented comparables.
✕ Likely Unlawful
- Mid-term hike, no clause. Raising rent during a fixed lease with no escalation clause — unenforceable.
- Under-noticed or verbal. A spoken or texted increase, or one served with less than the one month’s written notice section 441.060 requires.
- Discriminatory increase. A steeper raise aimed at a tenant because of a protected characteristic, no matter how small the amount.
- Program or local-rule breach. Exceeding a subsidized-program limit, or a local rule such as a Kansas City complaint protection.
Rent Increases Go Smoother With the Right Tenant
The tenants who fight every lawful increase are often the ones who show red flags on screening. Comprehensive credit, income, and eviction-history reports catch the mismatch before you ever sign a lease.
Frequently Asked Questions
How much can a landlord raise the rent in Missouri?
Missouri sets no statutory limit on the amount of a rent increase. There is no statewide rent control, and Missouri Revised Statutes section 441.043 bars counties and cities from adopting their own rent-control ordinances, so a landlord may generally raise the rent by any amount. What the law regulates is not the dollar figure but the process: the written notice, the timing within the tenancy, and the bar on discriminatory increases. Confirm current law and any subsidized-housing or local program rule before you set an increase.
Does Missouri have rent control?
No. Missouri has no statewide rent control, and under Revised Statutes section 441.043 no county or city, including a charter-form government, may enact, maintain, or enforce an ordinance that regulates the amount of rent charged for privately owned residential or commercial rental property. A narrow exception in the statute covers property the government itself owns and certain community-development-block-grant projects. The practical result is that the amount of a Missouri rent increase is not capped by state or local law.
How much notice must a Missouri landlord give before raising rent?
Missouri has no rent-increase-specific notice statute. A rent increase on a month-to-month tenancy works through the termination-and-new-terms mechanism: under Missouri Revised Statutes section 441.060, either party may end a month-to-month tenancy by written notice given at least one month before a periodic rent-paying date, and a landlord raises rent by giving that one month’s written notice of the new terms. State the new rent and its effective date in writing, and give at least a full month before the rent-paying date on which the new rent begins. During a fixed-term lease the rent cannot change until the term ends.
Can a Missouri landlord raise rent in the middle of a lease?
Generally no. During a fixed-term lease the rent is locked at the agreed amount for the whole term unless the written lease itself contains an escalation clause that expressly permits a mid-term change. Without that clause the increase is not enforceable, and a tenant who keeps paying the original rent is in the right. A landlord may raise rent at renewal, when a new term begins, or on a month-to-month tenancy by giving the one month’s written notice under section 441.060.
Is there a limit on how much rent can go up in Missouri?
No. There is no statutory percentage or dollar cap on a Missouri rent increase, because the state has no rent control and section 441.043 forbids local rent control. The real limits are procedural and motive-based: the one month’s written notice on a month-to-month tenancy, the rule that a fixed-term lease locks the rent until it ends, and the fair-housing bar on a discriminatory increase. The market, not a statute, sets the ceiling on the amount.
Can a Missouri landlord raise rent in retaliation for a complaint?
Missouri’s statutory protection here is limited, so be precise. Unlike many states, Missouri has no broad statewide statute that forbids a retaliatory rent increase across the board, and the sections often cited (441.870 and 441.880) address eviction immunity and stay of execution, not retaliatory rent increases. Protection can still exist through a subsidized-housing program rule, a specific lease term, common-law defenses, or a local ordinance. Kansas City, for example, bars a landlord from raising rent because a tenant complained about a health or safety condition. Because the protection is narrow and fact-specific, confirm the rule for your program and locality, and as a matter of practice do not time an increase to follow a tenant complaint.
Can a rent increase be illegal even though Missouri has no cap?
Yes. An increase that is lawful in amount can still be unlawful in how it is delivered or why it is imposed. An increase served with less than the one month’s written notice on a month-to-month tenancy does not take effect, and a mid-term increase with no escalation clause is unenforceable. An increase that singles out a tenant because of race, color, religion, national origin, ancestry, sex, disability, or familial status is housing discrimination under the federal Fair Housing Act and the Missouri Human Rights Act, no matter how modest the dollar amount.
How often can a Missouri landlord raise the rent?
On a month-to-month tenancy, as often as the notice mechanism allows, with at least one month’s written notice each time under section 441.060 and the new rent taking effect on a rent-paying date. During a fixed-term lease the rent cannot change until the term ends, absent an escalation clause. There is no state frequency cap, but a subsidized-housing program or a local rule can limit how often an increase is allowed, so check any program terms that apply to the unit.
Does a Missouri rent increase have to be in writing?
For a month-to-month tenancy, yes. Section 441.060 requires that the notice ending the old terms and setting the new ones be in writing, so a verbal announcement, a text, or an email the tenant never agreed to accept as a delivery method does not properly start the clock, and the old rent continues until a proper written notice is given. Put the current rent, the new rent, and the effective date in a dated written notice, and keep proof of how and when you delivered it.
Does the Missouri Human Rights Act protect a tenant’s source of income?
No. The Missouri Human Rights Act, at Revised Statutes section 213.040, prohibits housing discrimination because of race, color, religion, national origin, ancestry, sex, disability, and familial status, and the federal Fair Housing Act covers the same core classes. Neither adds a statewide source-of-income protection, so Missouri has no state law that requires a landlord to accept a Section 8 Housing Choice Voucher on that basis alone. A city or county could add its own protection, so confirm the local ordinance for the property’s location before relying on the absence of one.
What is the safest way for a Missouri landlord to raise rent?
Confirm the tenancy type first, because a fixed-term lease locks the rent until it ends unless the lease allows a change. Set the new rent by an objective, even-handed method and apply it consistently to comparable units. Serve a clear written notice that states the current rent, the new rent, and the effective date, giving at least the one month’s notice section 441.060 requires before the rent-paying date. Avoid timing the increase right after a tenant complaint, and keep a copy of the notice and proof of delivery. A consistent, documented, non-discriminatory increase is the one that holds up.
