Wisconsin Rent Increase Laws for Landlords (2026)
What Wisconsin law requires
Wisconsin has no statute about raising rent. That surprises most landlords, and it is the single most misreported fact in this area - plenty of sites will quote you a “Wisconsin rent increase notice law” that does not exist.
What Wisconsin does have is the notice required to end or change a month-to-month tenancy, and that is the mechanism you have to use: raising the rent is legally a change of terms. The period is 28 days' notice, in writing, under Wis. Stat. § 704.19.

How much can you raise it in Wisconsin?
There is no statutory ceiling. No cap, and no rent-increase statute. Wisconsin's periodic-tenancy notice is 28 days, not 30 - a detail that catches out landlords using an out-of-state template.
Only four US jurisdictions cap the size of an increase - California, Oregon, Washington and the District of Columbia. Wisconsin is not one of them, so the amount is a business decision, not a legal one. The usual constraint is practical: a tenant who leaves over an increase costs you a turnover, and a turnover costs more than the increase was worth.
Can you raise rent mid-lease in Wisconsin?
Not unless the lease says so. A fixed-term lease fixes the rent for its term, whatever the statute does or does not require about notice. An increase belongs at renewal, or on a month-to-month tenancy after proper notice.
Serving the notice so it holds up
Most rent increases that fall apart fall apart on the date, not the amount: the notice went out too late, or nobody can prove when it went out. Count the days from delivery, not from the day you wrote it, and keep the proof.
LandlordPro generates the notice against the state's rule, dates it, records when it was sent, and carries the new rent onto the rent roll on the right day so the ledger and the notice agree.

No. Wisconsin sets no cap on the size of an increase. Only California, Oregon, Washington and the District of Columbia cap the amount.
Can rent be raised during a lease in Wisconsin?
No, unless the lease itself provides for it. A fixed-term lease fixes the rent for the term; an increase belongs at renewal or on a month-to-month tenancy after notice.

Yes.
Do city rules change this in Wisconsin?
We found no local rent regulation in Wisconsin, but ordinances change faster than statutes. Check with the municipality before serving notice on a large increase.
