Wisconsin Rent Increase Notice

What Wisconsin law says

• DATCP: There are no state laws limiting the amount of a rent increase.
• Wis. Stat. 704.19(3) and DATCP: at least 28 days written notice to end a month-to-month tenancy; this is for termination, not a rent increase.
• Rent increases are barred if retaliatory (704.45(1)) or follow a tenant contacting law enforcement or health and safety services (704.44(1m)).
• DATCP guide: state rules do not cancel local ordinances, so check the municipality.

Steps for a landlord

• Check the lease for rent terms and any notice clause.
• Give written notice well before the new rent starts.
• Do not raise rent in response to a complaint or report.
• Check local ordinances.

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 pages we read do not set rent increase notice days; check the statute or a local attorney.
• Rules for fixed-term leases: the pages we read do not say beyond the lease terms controlling.
• Cities and counties can add their own rules, including rent control and extra notice requirements. Check your local rules too.
