Wisconsin Lease Agreement Requirements for Landlords

Wisconsin's lease requirements are shaped by both the Wisconsin Statutes (Chapter 704) and the detailed administrative code ATCP 134. These rules define what clauses a lease can and cannot include, how nonstandard provisions must be disclosed, and whether an oral lease is enforceable.

Oral vs. Written Leases

Wisconsin recognizes both oral and written leases:

• Oral Leases: Legally binding for terms of one year or less. However, they are extremely difficult to enforce in court because neither party has documented proof of the terms.
• Written Leases: Required for any lease with a term longer than one year to satisfy the Statute of Frauds. All lease terms must comply with ATCP 134.

Best Practice: Always use a written lease, regardless of the term length. A written lease protects both parties and is critical for enforcing late fees, security deposit deductions, and eviction proceedings.

Required Lease Disclosures and Attachments

Under ATCP 134, the following must be provided to the tenant before the lease is signed:

1. Identification of Owner/Agent: Written notification of who manages the property and can accept legal process.
2. Habitability Deficiencies: Written disclosure of any known code violations or serious hazards.
3. Utility Responsibilities: Written notice if water, heat, or electricity is not included in the rent.
4. Nonstandard Rental Provisions: A separate, clearly titled document (see below).
5. Security Deposit Inspection Rights: Written notice that the tenant has 7 days to document pre-existing damages.
6. Lead-Based Paint Disclosures: For properties built before 1978.

Nonstandard Rental Provisions

One of the most unique aspects of Wisconsin rental law is the Nonstandard Rental Provisions requirement.

If a landlord's lease contains any clause authorizing the landlord to take an action not expressly authorized by Wisconsin statutes (e.g., entering the premises for reasons beyond legal defaults, or deducting amounts from the security deposit for specific scenarios), those clauses must be:

1. Listed on a separate document titled "NONSTANDARD RENTAL PROVISIONS."
2. Provided to the tenant before the lease is signed.
3. Signed or acknowledged by the tenant separately.

If a nonstandard provision is not properly disclosed on this separate form, it is unenforceable—even if it appears in the body of the lease.

Prohibited Lease Clauses

ATCP 134 explicitly bans several types of lease clauses. A Wisconsin landlord cannot include terms that:

1. Waive the tenant's right to a habitable dwelling — The implied warranty of habitability cannot be eliminated by contract.
2. Allow self-help evictions — Clauses permitting a landlord to change locks, remove belongings, or shut off utilities without a court order are void.
3. Impose excessive late fees — Late fees that are unreasonable or that don't comply with the mandatory 5-day grace period are unenforceable.
4. Charge a fee for nonpayment of a late fee — A landlord cannot assess penalties on top of late fees.
5. Waive the right to recover the security deposit — The tenant's right to a deposit return and itemized statement cannot be waived.
6. Require tenants to pay for normal wear and tear — Clauses making tenants automatically responsible for repainting or carpet replacement at move-out are generally void.
7. Confession of Judgment — Unlike some states, residential confession of judgment clauses are not enforceable in Wisconsin.

Automatic Renewal and Holdover Tenancies

If a fixed-term lease expires and neither party gives notice, the tenancy usually converts to a month-to-month arrangement under the same terms (excluding the fixed-term duration). Landlords should plan ahead by offering renewal terms or serving a 28-day notice to terminate.
