Rent Increase Notice Requirements in Wisconsin

At a glance

Wisconsin's ordinary state-law framework

Wisconsin does not prescribe a general advance-notice period, percentage cap, or frequency limit for an ordinary residential rent increase. Local governments generally cannot create a rent ceiling instead: Wis. Stat. § 66.1015(1) prohibits a city, village, town, or county from regulating the amount of rent or fees charged for a residential rental dwelling unit.

Section 66.1015(2) preserves agreements governing rent for units owned or operated by the listed public bodies, as well as voluntary agreements with private persons who regulate rent or fees.

What trips people up

The 28-day period in § 704.19 is a termination rule, not a rent-change rule. The section requires written notice of the intent to terminate, says when a periodic tenancy ends, and states that the tenant loses the right to possession after the termination date. It does not say that 28 days' notice imposes a higher rent while the same tenancy continues.

Retaliation is a separate limit. Under § 704.45(1), a landlord may not increase rent when the evidence shows the increase would not have occurred but for retaliation over the tenant's listed complaints or exercise of a tenancy right. Subsection (2) excludes the prohibited increase when determining whether unpaid rent permits an action for possession.

Common questions

Does Wisconsin require 28 days' notice of a rent increase?

No general state statute says so. Section 704.19 uses 28 days for terminating most periodic tenancies; its notice must state an intent to terminate and a termination date.

Can a Wisconsin city adopt rent control?

Generally no. Section 66.1015(1) prohibits cities, villages, towns, and counties from regulating the amount of rent or fees for residential rental units. Subsection (2) preserves the limited agreement categories described above.

What if the increase follows a housing-code complaint?

Section 704.45 prohibits a rent increase that would not have occurred but for retaliation over a listed protected act. The cited section does not state a general damages formula for every defective or excessive increase.
