Wisconsin Rent Increase Rules at a Glance
| Statewide rent cap | NO — Wisconsin has no statewide rent cap. There is no maximum percentage or dollar limit on how much a landlord can raise rent. Landlords may raise rent by any amount as long as proper notice is given and the increase is not retaliatory or discriminatory. |
| Notice required before increase | 28 days written notice for month-to-month tenancies (Wis. Stat. § 704.19). For tenancies where rent is paid on a basis less than monthly, notice must equal at least one full rent-paying period. For year-to-year agricultural tenancies, 90 days notice is required. For fixed-term leases, landlords cannot raise rent during the lease term unless the lease specifically allows it — any increase takes effect only at lease renewal. |
| How often rent can be raised | No statutory limit on frequency. For month-to-month tenants, a landlord may raise rent as often as every rental period (monthly) as long as 28 days written notice is given each time. For fixed-term leases, rent can only change at lease renewal unless the lease itself provides otherwise. |
| During a fixed-term lease | NO — A Wisconsin landlord generally cannot raise rent during a fixed-term lease unless the lease agreement itself contains a specific provision allowing mid-lease rent increases. If no such clause exists, the rent remains locked for the entire lease term. Any increase takes effect only when the lease expires or renews. |
Retaliatory increases: YES — Wisconsin prohibits retaliatory rent increases under Wis. Stat. § 704.45. A landlord may not increase rent, decrease services, bring an eviction action, or refuse to renew a lease if there is a preponderance of evidence that the action is retaliation against a tenant for: (1) making a good faith complaint about a defect in the premises to an elected official or local housing code enforcement agency; (2) complaining to the landlord about a violation of Wis.
Stat. § 704.07 or a local housing code; or (3) exercising any legal right relating to residential tenancies. If you believe your rent increase is retaliatory, you may raise this as a defense in court.
Wisconsin Cities With Local Rent Control
NONE — No cities in Wisconsin have local rent control ordinances. Wisconsin state law (Wis. Stat. § 66.1015) expressly prohibits any city, village, town, or county from regulating the amount of rent charged for residential rental units.
Exempt properties: Because Wisconsin has no rent cap or rent control, there are no exemption categories. All private residential rental properties — including new construction, single-family homes, condos, and small landlord units — are subject to the same rules: no cap on increases, 28 days notice for month-to-month tenancies.
The only exception is government-owned or government-subsidized housing (e.g., public housing authorities, Section 8, WHEDA-funded units), which may have federally or contractually imposed rent limits.
State preemption: YES — Wisconsin fully preempts local rent control. Under Wis. Stat. § 66.1015, no city, village, town, or county may regulate the amount of rent or fees charged for a residential rental dwelling unit. This means no Wisconsin municipality can pass its own rent cap, rent stabilization, or rent control ordinance.
The only exception is that a municipality or housing authority may regulate rent on units it directly owns or operates, or through voluntary agreements with private landlords.
What to Do If Your Rent Increase Is Illegal
If you believe a rent increase is illegal — for example, retaliatory, discriminatory, or imposed mid-lease without a lease clause allowing it — you may be able to: (1) File a complaint with the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) at datcp.wi.gov, which enforces Wis.

Adm. Code ch. ATCP 134; (2) Contact a local tenant rights organization such as the Tenant Resource Center (tenantresourcecenter.org); (3) File a complaint with HUD or the Wisconsin Equal Rights Division if you suspect housing discrimination; (4) File an action in Wisconsin Small Claims Court — under Wis.
Stat. § 100.20(5), many tenants can recover twice the amount of actual monetary loss plus court costs and reasonable attorney fees if the court finds a violation of ATCP 134; (5) Raise retaliation as a legal defense if the landlord takes you to eviction court after you complained about housing conditions. Check with your local court or a legal aid organization before acting.
Other Wisconsin rent rules: Wisconsin does not have a standalone rent increase statute — rent increase notice requirements are derived from the general tenancy termination notice rules in Wis. Stat. § 704.19, because a landlord who raises rent effectively offers new lease terms that the tenant may accept or refuse.
Also, Wis. Stat. § 66.1015 additionally prohibits municipalities from imposing inclusionary zoning requirements that would mandate below-market-rate units in new developments.
Wisconsin law (ATCP 134) also prohibits landlords from including certain provisions in rental agreements, such as requiring tenants to waive their rights — any lease clause waiving a tenant’s right to challenge a retaliatory increase would be void.

Understanding Wisconsin Rent Increase Laws
Whether a Wisconsin rent increase is legal depends on the cap (if any), the notice given, and whether the increase is retaliatory. Wisconsin rent increase laws protect tenants from surprise hikes by requiring a minimum notice period before any increase takes effect.
If you believe a Wisconsin rent increase violates these rules, document the notice you received, check the math against the cap, and contact your local housing authority or legal-aid office.
Knowing the Wisconsin rent increase rules before your lease renews puts you in a much stronger position.
