Missouri Rent Increase Notice

What Missouri law says

• The guide says 'A landlord can evict the tenant or raise rent with only one month's notice.'
• It says one month's notice means a full calendar month and must include a full rental period.
• RSMo 441.060 says a tenancy of less than one year may be ended by one month's notice in writing; it does not address rent increases.
• The guide does not mention rent control.

Steps for a landlord

• Pick an effective date at least one full rental period after notice.
• Give the notice before the start of that period.
• Put the notice in writing and keep a copy.
• Check the lease for its own notice terms.

What to put in the notice

• The tenants' names and the rental address
• The current rent and the new rent
• The date the new rent starts, after the required notice period
• The date of the notice and how it was delivered
• Your name and signature

Things to watch

• The guide does not say whether a rent increase notice must be written. Check the statute or a local attorney before relying on this.
• Fixed-term leases: the pages we read do not say.
• Cities and counties can add their own rules, including rent control and extra notice requirements. Check your local rules too.
