Wisconsin: Rent Increase Notice Requirements

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.
