Wisconsin Landlord-Tenant Law 2026: The Plain-English Guide
Wisconsin's landlord-tenant rules live mostly in ATCP 134 (an administrative code, not just statutes) — which surprises out-of-state landlords. The headline quirks: 21-day deposit returns, 5-day pay-or-vacate notices, and 12 hours' entry notice (not 24).
Security deposits
- No state cap on the amount.
- Return within 21 days of move-out, with a written itemized statement.
- ATCP 134 requires specific disclosures at the time you collect the deposit — including any pre-existing damage and the tenant's right to a check-in sheet.
- Penalty: violations of ATCP 134 can mean 2x damages plus attorney's fees — and tenants can bring claims under Wisconsin's consumer protection statutes.

Rent rules
- No rent control — prohibited statewide.
- Late fees must be in the lease and reasonable.
- Raising rent: 28 days' notice for month-to-month tenancies (Wisconsin uses 28 days, not 30 — another quirk). See how to raise rent legally.
Eviction in Wisconsin
1. 5-Day Notice to Pay or Vacate for nonpayment.
2. 14-Day Notice for lease violations — no right to cure if it's the second violation within 12 months.
3. 28-Day Notice to terminate a month-to-month tenancy.
4. File in Small Claims Court — eviction actions, low fees, fast hearings.
Uncontested cases typically resolve in 3–5 weeks. Self-help is illegal. Full process: how to evict a tenant.
Repairs and habitability
- Implied warranty of habitability; local housing codes (Milwaukee, Madison) add enforcement.
- Tenant remedies after written notice: repair-and-deduct (with procedures), rent abatement, or lease termination for serious violations.
- Retaliation is prohibited.
Entry rights
- 12 hours' notice required — half the 24 hours most states use. Entry at reasonable times.
- Emergencies excepted. Put the 12-hour rule in your lease so everyone's clear.
The bottom line
Wisconsin is fast and landlord-manageable, but the numbers are all slightly off from the national norms: 21 days (not 30) for deposits, 28 days (not 30) for termination notices, 12 hours (not 24) for entry. Learn Wisconsin's numbers and you're fine; assume the national defaults and you'll trip.
