Wisconsin Landlord-Tenant Laws (2026): Deposits, Notice, and Tenant Rights

Wisconsin has no statutory cap on security deposits, and landlords must return the deposit within 21 days of move-out. Landlords must give at least 12 hours of advance notice before entering a rental unit, and rent control is preempted statewide.

Security deposits in Wisconsin

Wisconsin does not set a maximum dollar amount for security deposits. A landlord can legally require any amount, though requiring an unusually high deposit may signal problems with a tenancy. Whatever amount is charged must be clearly stated in the rental agreement. At move-out, the landlord has 21 days to either return the full deposit or provide a written, itemized accounting of any deductions. Deductions must be for actual damages beyond normal wear and tear, unpaid rent, or other charges specifically authorized by the lease.

Wis. Stat. 704.28 sets the 21-day deadline and limits what a landlord may withhold, but it contains no penalty of its own. The itemized statement and the tenant's remedy come from the DATCP rental-practices rule. Wis. Admin. Code ATCP 134.06(4) requires a written statement describing each item withheld and the amount claimed for it, within the same 21-day window.

Enforcement runs through Wis. Stat. 100.20(5). A tenant who suffers a pecuniary loss because of a violation of an order issued under that section, which is how the ATCP 134.06 deposit rule is enforced, may sue and shall recover twice the amount of the loss, together with costs and a reasonable attorney fee. The doubling is not discretionary and does not turn on proving bad faith; the tenant has to show the violation and the resulting loss.

Wisconsin does not require landlords to hold deposits in a separate escrow account or pay interest on deposits, though the rental agreement may impose those terms voluntarily.

When can a landlord enter? Notice rules

Wisconsin requires landlords to give tenants at least 12 hours of advance notice before entering a rental unit (Wis. Admin. Code ATCP 134.09). This rule applies to routine inspections, showings to prospective tenants or buyers, and non-emergency repairs. The notice should state the reason for entry and the approximate time. Entry must occur at a reasonable hour unless the tenant consents otherwise.

The 12-hour minimum is a firm rule, not a guideline. A landlord who repeatedly enters without proper notice can be found in violation of ATCP 134, which is enforced by the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP). Tenants who experience repeated unauthorized entry can file a complaint with DATCP or assert the violation as a defense in eviction proceedings.

Emergency exceptions apply when there is an immediate threat to life, health, or property, such as a fire, flood, or burst pipe. In those situations a landlord may enter without advance notice to prevent further damage. The landlord should still document the reason for the emergency entry.

Ending a lease: notice to vacate

To end a month-to-month tenancy in Wisconsin, either the landlord or the tenant must give at least 28 days written notice (Wis. Stat. 704.19(3)). Two separate requirements apply and both have to be met. The 28 days is the minimum length of the notice, and under Wis. Stat. 704.19(2)(b)1 a periodic tenancy can be terminated by notice only at the end of a rental period.

That second rule is the one people miss. Notice given in the middle of a month does not end a month-to-month tenancy 28 days later. If notice is delivered on the 10th with rent due on the first, the end of that month is only about three weeks away, so the earliest valid termination date is the last day of the following month.

Under Wis. Stat. 704.19(5), a notice naming too early a date is still valid but does not take effect until the first date that could properly have been specified. The parties may agree expressly on another method of termination, but Wis. Stat. 704.19(2)(a)1 requires that agreement to be established by clear and convincing proof.

Fixed-term leases end at the lease expiration date; no separate notice is needed unless the lease itself requires one. If a tenant remains in the unit after the lease expires without a new agreement, Wisconsin courts generally treat the tenancy as month-to-month, and the 28-day notice rule then applies.

For nonpayment of rent or a lease violation, different procedures apply. Wisconsin landlords must provide a 5-day notice to pay or vacate for nonpayment, or a notice to remedy or vacate for a lease violation, before proceeding with an eviction. See the Wisconsin eviction notice page for step-by-step requirements.

Repairs and the warranty of habitability

Wisconsin landlords are required to keep rental units in a habitable condition under Wis. Stat. 704.07. This includes maintaining the roof, walls, windows, plumbing, heating, and electrical systems in working order. The duty to repair generally falls on the landlord unless the tenant caused the damage. Tenants must notify the landlord of defects; the landlord then has a reasonable time to make repairs.

Wisconsin does not provide a statutory repair-and-deduct remedy. A tenant cannot simply hire a repair contractor and subtract the cost from rent. Instead, if the landlord fails to make required repairs after notice, the tenant's main remedies are rent abatement (a court-ordered reduction in rent proportional to the loss of habitability), termination of the lease if conditions are severe, or a DATCP complaint. Rent abatement requires a court proceeding; tenants should not withhold rent unilaterally without legal counsel, because doing so can trigger an eviction action.

Serious habitability failures, such as no heat in winter or a broken sewage system, may also allow tenants to notify DATCP or local housing inspectors, who can cite the landlord independently. Documentation with dated photos and written communications to the landlord is essential before pursuing any remedy.

Rent, late fees, and rent control

Wisconsin does not cap the amount of a late fee, but the fee must be expressly stated in the rental agreement or lease; a landlord cannot charge a late fee that was not disclosed before the tenancy began. Wisconsin also has no statutory grace period before a late fee may be assessed, so the rental agreement governs when rent is considered late. DATCP guidance encourages landlords to make late-fee terms clearly visible in the rental agreement.

Rent control is preempted in Wisconsin. Wis. Stat. 66.1015(1) provides that no city, village, town or county may regulate the amount of rent or fees charged for the use of a residential rental dwelling unit, and subsection (3) separately bars local inclusionary zoning requirements. That reaches rent stabilization and rent ceilings.

The preemption is written in terms of the amount of rent, not the procedure for changing it, so by its own terms it does not address local rent-increase notice requirements.

No Wisconsin statute requires a landlord to give advance notice of a rent increase on a month-to-month tenancy. In practice, a landlord who wants a higher rent gives a 28-day notice under Wis. Stat. 704.19 ending the existing tenancy at the end of a rental period and offers a new agreement at the new rate, or the parties simply agree to the change. For fixed-term tenants, rent is locked at the lease rate until the lease expires.

If you have a landlord-tenant dispute in Wisconsin

When a dispute arises, your most powerful tool is contemporaneous documentation. Send all repair requests, notices, and complaints in writing (email with read receipts or certified mail) and keep copies. A written paper trail protects both parties and is often decisive if the dispute reaches small claims court or a DATCP hearing.

For deposit disputes, you do not need an attorney. Wisconsin small claims court handles claims up to $10,000 and is designed for self-represented litigants. File in the county where the property is located, and bring your lease, move-in checklist, move-out photos, and the landlord's itemized deduction statement (or evidence it was never sent).

For habitability or entry violations, file a complaint with the Wisconsin DATCP Consumer Protection Hotline or your local housing inspector. DATCP can investigate ATCP 134 violations and, in serious cases, impose fines or issue orders against the landlord. If the issue is a pattern of discrimination or retaliation, the Wisconsin Equal Rights Division handles fair-housing complaints.

Legal aid is available for income-eligible tenants through Wisconsin Judicare (northern Wisconsin), Legal Action of Wisconsin (southeastern Wisconsin), and other regional providers. The State Bar of Wisconsin's Lawyer Referral Service can connect tenants or landlords with a licensed attorney for a paid consultation.

This article is general legal information, not legal advice. Landlord-tenant rules vary by state and city and change, and some cities add their own ordinances. For advice about a specific situation, consult a licensed attorney or your state housing agency.
