Wisconsin Landlord-Tenant Laws: The Complete 2026 Overview

Wisconsin sets no cap on the deposit amount, but ATCP 134.06 locks down the return: a landlord must refund the deposit within twenty-one days after the tenant surrenders the unit. Any amount withheld requires a written statement of claims under ATCP 134.06(4), describing each item of damage or other claim and the amount withheld for it. Two widely repeated beliefs about that clock are wrong. A written forwarding address is not a condition precedent: ATCP 134.06(2) and Wis. Stat. 704.28(4) tie the twenty-one days to the termination date of the rental agreement, to the date a new tenancy begins if the landlord re-rents early, or to the date the landlord learns the tenant has vacated after the termination date – and ATCP 134.06(5) provides that a landlord who has otherwise complied is not in violation merely because the postal service could not complete delivery. And Wisconsin has no statutory presumption of bad faith. The teeth are in Wis. Stat. 100.20(5): a tenant who suffers a pecuniary loss from any ATCP 134 violation recovers twice that loss plus costs and a reasonable attorney fee, negligent violations included, and Boelter v. Tschantz, 2010 WI App 18, makes the fee award mandatory on a successful claim. Where the landlord never delivered the accounting at all, Pierce v. Norwick, 202 Wis. 2d 587 (1996), runs the doubling on the deposit itself. Wisconsin does not require the landlord to hold the deposit in a separate account or to pay interest on it. Disputes are heard in Circuit Court, with smaller claims handled through small claims procedure.

Wisconsin requires a written notice before an eviction can be filed, and the type depends on the tenancy and the ground. For nonpayment of rent under a lease of one year or less, the landlord serves a five-day notice giving the tenant a chance to pay or move, under Wis. Stat. section 704.17; a five-day cure-or-quit notice covers many lease violations, while repeat or serious violations can support a fourteen-day unconditional notice. If the tenant does not comply, the landlord files an eviction action in the Circuit Court where the property sits, and the tenant has a statutory window to respond before a hearing. Self-help evictions – changing locks, removing doors, or shutting off utilities – are illegal in Wisconsin. Only a sheriff acting on a writ of possession may physically remove a tenant.

Wisconsin does set a statutory entry-notice period: ATCP 134.09 requires a landlord to give at least twelve hours’ advance notice before entering an occupied unit for a non-emergency purpose such as inspection, repairs, or a showing, and the entry must occur at reasonable times. This sits alongside the tenant’s common-law right to quiet enjoyment. In practice, most landlords give twenty-four hours’ written notice, which is the accepted best practice and a more defensible record. Genuine emergencies such as fire, flooding, or a gas leak permit immediate entry without notice. A landlord who repeatedly enters without proper notice can face liability under the same double-damages framework that governs deposits, so spelling out the entry procedure in the lease is the single best way to avoid a dispute.

Wisconsin has no rent control. There is no statutory cap on how much a landlord may raise the rent, and state law bars local governments from adopting rent control. During a fixed-term lease the rent is locked at the agreed figure unless the lease itself allows an increase; a raise takes effect only at renewal or on a month-to-month tenancy. For a month-to-month tenancy, the landlord must give at least twenty-eight days’ written notice of the increase under Wis. Stat. section 704.19 – the same notice used to change or end the tenancy. The limits that do apply are anti-retaliation and anti-discrimination: a landlord may not raise rent to punish a tenant for a good-faith code complaint or for exercising a legal right, and may not raise it on a discriminatory basis under fair-housing law.

Wisconsin does not set a fixed dollar cap on late fees, and chapter 704 imposes no late-fee conditions at all – they come from Wis. Admin. Code ATCP 134.09(8), and there are three of them. First, no landlord may charge a late rent fee or penalty except as specifically provided under the rental agreement, so a fee the lease never mentions does not exist. Second, before charging any late fee the landlord must apply all rent prepayments received from that tenant to offset the rent owed. Third, no landlord may charge any fee or penalty for nonpayment of a late fee, which blocks fees stacked on fees. On top of the rule, the amount must be a reasonable estimate of the landlord’s actual loss rather than a punitive penalty. ATCP 134.09(8) contains no dollar figure and no percentage, and no percentage is automatically safe, so a modest fee tied to documented costs is far easier to defend than a round number. Wisconsin sets no statutory grace period, so any grace window is purely contractual, and the fee cannot be imposed until the rent is actually past due. A fee that operates as a penalty rather than a genuine damages estimate is unenforceable, and improper fees can expose a landlord to the code’s double-damages remedy.

Wisconsin law requires a landlord to keep the premises in a fit and habitable condition, and Wis. Stat. section 704.07 governs the repair duty and the doctrine of untenantability. The tenant triggers the duty by giving written notice of the defect – certified mail with return receipt is best – and the landlord must act within a reasonable time. Section 704.07 fixes no number of days at all, and no Wisconsin statute supplies one; reasonableness scales to severity, so a gas leak, a loss of heat in a Wisconsin winter, a loss of water or a sewage backup demands action within hours, while a routine repair is measured against what a reasonable landlord would have done. If a condition renders the premises untenantable and the landlord fails to repair after notice, the tenant may be entitled to rent abatement or, in serious cases, to move out and end the tenancy. The ATCP 134 code reinforces these duties and bars a landlord from misrepresenting the condition of a rental. Retaliation against a tenant who asserts habitability rights is prohibited.

Wisconsin codifies specific reasons a tenant may end a fixed-term lease early without owing the full balance. The most important is Wis. Stat. section 704.16, which lets a victim of domestic abuse, stalking, or sexual assault terminate the tenancy after giving written notice with a certified copy of a qualifying document such as an injunction, a criminal complaint, or a condition of release; the tenant is not liable for rent past the end of the month following notice or the move-out. Military servicemembers are protected by the federal Servicemembers Civil Relief Act, and a tenant may terminate when the premises become untenantable under section 704.07. For a tenant who simply leaves without a statutory ground, Wis. Stat. section 704.29 imposes a duty on the landlord to mitigate damages by making a reasonable effort to re-rent, so the departing tenant owes only the vacancy gap, not the entire remaining term.

Ending a Wisconsin tenancy depends on its type. A month-to-month tenancy is terminated by written notice of at least twenty-eight days under Wis. Stat. section 704.19, from either party. A fixed-term lease generally runs to its end date and cannot be cut short without a statutory ground or mutual written agreement. Wisconsin does not require just cause to decline to renew a lease, and an automatic-renewal clause is enforceable only on the statutory terms: under Wis. Stat. 704.15, reinforced by ATCP 134.09(3), such a clause is not enforceable against the tenant unless the landlord gave the tenant separate written notice of the pending renewal or extension at least fifteen days but not more than thirty days before the deadline for the tenant’s own notice. Miss that window, or fall outside it on either side, and the renewal cannot be enforced. A tenant who stays past the lease end date becomes a holdover; Wisconsin allows double rent against a holdover who remains without consent under Wis. Stat. section 704.27, and the landlord must pursue possession through an eviction action in Circuit Court rather than self-help. When any tenancy ends, the twenty-one-day deposit-return rule of ATCP 134.06 still applies to the move-out.

For an actual pet, Wisconsin lets a private landlord set pet policies, including breed and weight restrictions and a no-pet rule, and any pet deposit is governed by the same security-deposit rules as the rest of the deposit. Assistance animals are treated completely differently. Under the federal Fair Housing Act and the Wisconsin Open Housing Act, a service animal or emotional support animal is not a pet – a landlord may not charge any pet deposit, fee, or rent, and may not apply a breed or weight restriction or a no-pet policy to it. When the disability or the animal’s role is not obvious, the landlord may request reliable documentation from a licensed professional, but may not demand certification or registration. The tenant remains liable for any actual damage the animal causes, and a reasonable accommodation must be granted unless it imposes an undue burden.

Wisconsin adds real state-level rules on top of the federal screening baseline. With the applicant’s written authorization, a landlord may pull a consumer report covering credit, rental history, income, and criminal records – the Fair Credit Reporting Act requires a permissible purpose and consent first. Wisconsin then limits the credit-check fee to the landlord’s actual cost, and under ATCP 134.05 the landlord must notify the applicant before charging it and provide a copy of the report. If a denial, a higher deposit, or a co-signer requirement rests in any part on a consumer report, the FCRA requires an adverse action notice naming the reporting agency. The Wisconsin Open Housing Act, Wis. Stat. section 106.50, also lists lawful source of income as a protected class. Note carefully what the statute does and does not say: section 106.50(1) and (1m)(h) name the class, but nothing in section 106.50 defines “lawful source of income,” so whether a federal Housing Choice Voucher falls inside it is not answered by the statutory text and should be checked with Wisconsin counsel before you rely on either answer. What is clear is that a landlord may not treat the class itself as a disqualifier, and that some municipalities have adopted their own source-of-income ordinances covering voucher holders.
