Landlord–tenant law in Wisconsin
The rules that come up in practice — returning a deposit, charging a late fee, raising the rent — each read against the Wisconsin statute and quoted on its own page.
Security deposit return
Full rule →21 days
The 10th shortest of 49 states with a deadline.
Wis. Admin. Code ATCP 134.06(2)
Late fee limit
Full rule →No statutory cap
No mandatory grace period — a fee may be charged as soon as rent is late, if the lease provides for it.
Wis. Admin. Code ATCP 134.09(8)
Rent increase notice
Full rule →28 days
From the month-to-month termination rule, not a rent-increase statute. The 3rd shortest of 49.
Wis. Stat. 704.19
What is distinctive about Wisconsin
- Deposits: 21 days. An administrative rule rather than a statute. Start date varies with how the tenancy ended, including re-renting.
- Late fees: uncapped by statute, so the limit is whatever a court would call reasonable. There is no mandatory grace period.
- Rent increases: 28 days, borrowed from the termination rule because Wisconsin has no rent-increase statute.
The mistake that costs the most here
Treating “no statutory cap” as no limit. A late fee in Wisconsinis liquidated damages, and one set as a round percentage with no relation to the landlord’s actual cost is the kind of clause a judge strikes out.
Where these figures come from
Each rule above was read against the section it cites and the statutory wording is quoted on the dedicated page, so you can check it rather than take our word for it. That matters more than it sounds on this subject: when we read all 51 jurisdictions we found several widely-published figures to be wrong, including a Kentucky deposit deadline that does not exist, a South Dakota one reported as 14 days when the statute says 21, and late-fee caps for nine states that actually come from their self-storage statutes.
Local ordinances can add requirements the state does not, and statutes move — Washington, Connecticut, Nevada, Rhode Island and Maryland have all changed in the last three years. Each figure carries the date we read it.
States with the same deposit deadline
Common questions about Wisconsin
- How long does a Wisconsin landlord have to return a security deposit?
- 21 days under Wis. Admin. Code ATCP 134.06(2).
- What is the maximum late fee in Wisconsin?
- Wisconsin sets no statutory cap. A reasonableness standard applies instead, so a fee has to bear some relation to what the late payment actually costs the landlord.
- How much notice before a rent increase in Wisconsin?
- 28 days under Wis. Stat. 704.19, which is the month-to-month termination rule — Wisconsin has no statute specifically about rent increases.
- Does Wisconsin have rent control?
- No statewide frequency limit is verified for Wisconsin. Only California, Oregon and Washington cap the amount of an increase statewide; some cities do so locally.
