Missouri Rent Increases: Can Your Landlord Raise Rent Mid-Lease?

If you're renting in Missouri and have received notice of a rent increase partway through your lease, you may be wondering if that's legal. Missouri renters deserve clear, accurate information about their rights regarding rent hikes and lease agreements. Knowing what state law allows can help you take the right steps and protect your housing.

Missouri Law on Rent Increases During a Lease

In Missouri, the law distinguishes between fixed-term leases (for example, a 12-month agreement) and month-to-month rental arrangements. Your rights depend on your lease type.

Fixed-Term Lease Agreements

If you have a written lease for a specific period (like one year), your landlord generally cannot increase your rent until the lease ends unless your lease specifically says otherwise. The rent amount agreed upon at the beginning of the lease must remain unchanged for its entire term, unless:

• The lease contains a clear provision allowing mid-lease rent increases under specific conditions.
• Both you and the landlord formally agree in writing to amend the lease and adjust the rent.

Unless these exceptions apply, a mid-lease rent increase is not legal in Missouri. Consult your lease agreement to see what it says about rent changes.

Month-to-Month and Other Periodic Leases

If you're renting month-to-month (no end date specified), landlords are allowed to raise rent. However, they must provide written notice at least one month (30 days) before the increase takes effect.¹ This is governed by Missouri Revised Statutes Section 441.060.

The notice period applies to any change in lease terms, including a rent hike. Rent increases can only take effect at the start of a new rental period after notice has been properly delivered.

How Does a Landlord Notify You of a Rent Increase?

The notice usually must be written. There's no official Missouri government form for rent increase notices, but a written letter dated and signed by the landlord is typical. This must be delivered per your lease terms (hand delivery, mail, or as outlined in your lease).

What Should You Do if Your Landlord Raises Rent Mid-Lease?

If you get a mid-lease rent increase and your lease does not allow for it, you are not required to pay the higher rent. Consider these steps:

• Review your lease agreement and check for any clauses about rent adjustments.
• Politely notify your landlord in writing that your lease does not permit a rate change until renewal.
• If your landlord persists or threatens eviction, you can seek legal advice or file a complaint with a local civil court (there is no dedicated housing tribunal in Missouri).

Relevant Official Forms and Where to Find Help

• Missouri Notice to Terminate Tenancy (Form 441.060): Used if you wish to leave after a rent increase on a month-to-month lease. You must give your landlord at least 30 days’ written notice (see the sample at Missouri Revised Statutes Section 441.060). Example: If you can't afford the increase, use this written notice to advise your landlord you are moving out.
• Small Claims Court Forms: If you need to recover money for overpaid rent, access forms at the Missouri Courts Small Claims Forms page.

Which Tribunal Handles Landlord-Tenant Issues?

In Missouri, rental disputes are handled by your county or city’s Circuit Court, not by a separate housing tribunal.

Relevant Missouri Legislation

The main law covering tenancies, including when rent can be increased, is Missouri Revised Statutes Section 441.060 (Termination of tenancy—notice, how given). Always refer to current legislation or seek local legal help for the latest updates.
