How to Become a Landlord in Wisconsin: Disclosures, Deposits, and Leases

To become a landlord in Wisconsin, you need to get the property into legally habitable condition, make a specific set of pre-tenancy disclosures, use a lease that avoids Wisconsin’s long list of prohibited provisions, and follow strict rules for deposits, entry, and eviction under Wis. Stat. ch. 704 and ATCP 134. The state does not license landlords, but it does impose precise procedural duties, and missing any of them can void your lease or expose you to double damages in court.

Here is the order of operations that actually works, starting with the business decisions you make before a tenant ever walks through the door.

Set Up the Business Side Before You List the Unit

Wisconsin does not require you to form a business entity to rent out property, but holding a rental in your personal name means any lawsuit against the property goes directly at your personal savings, home, and other assets. A limited liability company creates a legal wall between the rental and the rest of what you own.

You form a Wisconsin LLC by filing articles of organization with the Department of Financial Institutions. You will need a registered agent with a physical Wisconsin address. The DFI accepts online and paper filings, and expedited processing costs an additional $25. If you plan to own more than one rental, putting each property in its own LLC keeps a claim against one from reaching the others. The protection only holds if you keep the LLC’s finances fully separate from your personal accounts and maintain proper records. Commingling funds or ignoring corporate formalities lets a court “pierce the veil” and treat the LLC as though it never existed.

Landlord insurance is not legally required, but your standard homeowner’s policy almost certainly does not cover a property you rent to others. A landlord policy generally covers property damage from fire and storms, liability for injury claims, and lost rental income if a covered event forces tenants out during repairs.

Check your city before you do anything else. Many Wisconsin municipalities impose their own registration or inspection requirements on top of state law. Milwaukee, for example, requires all non-owner-occupied properties to register with the Department of Neighborhood Services. Other cities require periodic rental inspections or separate occupancy permits. Call your local building or housing department before you list the unit, because unresolved municipal code issues can turn into state-level disclosure obligations later.

Make Sure the Property Meets Wisconsin’s Habitability Rules

Wis. Stat. 704.07 puts the duty to maintain rental property squarely on the landlord, and any lease clause trying to waive these duties is void.¹ Before you rent, confirm the unit meets each of these standards:

Common areas you control are in a reasonable state of repair.
Any building system you agreed to supply — heat, water, air conditioning — works and is maintained.
Structural components, including the roof, walls, and foundation, are sound.
Plumbing, wiring, machinery, and equipment that came with the unit function properly, unless a local housing code assigns that responsibility differently.
The property complies with any applicable local housing code.

You are not responsible for repairs caused by the tenant’s own negligence or misuse. Everything else is on you.

Heating Capacity Must Be Disclosed

Wisconsin’s administrative code requires you to disclose before move-in whether the heating system can maintain at least 67°F in all living areas during every season the unit may be occupied. If you say nothing, the law treats the system as if it meets that standard, and you are liable when it doesn’t.²

Required Disclosures Before Any Deposit Changes Hands

Wisconsin front-loads disclosure. Several items below are preconditions to collecting a security deposit at all, not just paperwork you can catch up on later.

Any building or housing code violation you actually know about that affects the unit or common areas, presents a significant threat to health or safety, and has not been corrected.¹
Any heating-system limitation under the 67°F standard above.
Whether the tenant is responsible for utilities, and if the building is not individually metered, how charges are divided.
For any property built before 1978, the federally required lead-based paint disclosures: a copy of the EPA pamphlet “Protect Your Family From Lead in Your Home,” disclosure of any known lead hazards, and a lead warning statement in the lease.³
The name and address of the property owner and any authorized property manager.

Wisconsin allows oral leases for terms of one year or less, but a written agreement protects both sides. If you use a written lease, give the tenant a copy to keep.

Write a Lease That Won’t Be Voided

This is where new Wisconsin landlords get hurt. Wis. Stat. 704.44 and ATCP 134.08 list specific clauses that make an entire residential lease void and unenforceable, not just the offending clause. A lease is void if it does any of the following:⁴

Attempts to relieve the landlord of the duty to deliver or maintain a habitable unit.
Authorizes eviction by any method other than the court process under Chapter 799.
Accelerates rent on default, or waives the landlord’s duty to try to re-rent the unit and reduce the tenant’s losses.
Requires the tenant to pay the landlord’s attorney fees in any dispute (a court can still award fees under Ch. 799 or 814).
Has the tenant agree in advance to any accusation of a lease violation.
Says the landlord is not liable for property damage or personal injury caused by the landlord’s own negligence.
Holds the tenant responsible for injuries from causes beyond their control, or for damage from natural disasters or other people.
Allows the landlord to raise rent, cut services, or pursue eviction because the tenant contacted law enforcement, health, or safety services.

If you are starting from a template you found online, compare it to this list clause by clause. One prohibited provision is enough to lose the whole lease.

Screen Applicants Within Fair Housing Limits

Wisconsin’s Open Housing Law goes further than the federal Fair Housing Act. Federal law prohibits discrimination based on race, color, religion, sex, national origin, disability, and familial status.⁵ Wisconsin adds marital status, age, ancestry, lawful source of income, sexual orientation, and status as a victim of domestic abuse, sexual assault, or stalking.⁶

Build your screening criteria before you show the unit. Keep them objective — income, employment, rental history — apply them the same way to every applicant, and leave protected characteristics off your application entirely. Consistent written criteria are what you will rely on if a rejected applicant challenges your decision.

Credit Checks and Adverse Action

If you run a credit or background check, the federal Fair Credit Reporting Act requires written permission from the applicant before you pull the report. Wisconsin caps the credit-check fee at your actual cost, up to the limit in Wis. Stat. 704.085, and requires you to give the applicant a copy of the report.⁷ If you reject an applicant based wholly or partly on a credit or background report, you must send an adverse action notice explaining the reason and identifying the reporting agency.⁸

Earnest Money Deposits

You cannot accept an earnest money deposit until you have identified which unit the applicant is being considered for. If you reject or the applicant withdraws, you must return the full deposit by the end of the next business day. If you do not approve the application within three business days — or a longer period the tenant agrees to in writing, up to 21 calendar days — the deposit must also be returned.⁷

Take and Hold the Security Deposit by the Book

Wisconsin does not cap the amount of a security deposit, but the handling rules are strict and the penalties for mistakes are among the most commonly litigated issues in landlord-tenant law.

Check-In Notice

Before you accept the deposit, give the tenant written notice that they have at least seven days after the start of the tenancy to inspect the unit and report pre-existing damage. The notice must also tell them they can request a list of damages charged to the previous tenant’s deposit. If they request it, you have 30 days to provide the list, or seven days after you notify the previous tenant of the deductions, whichever is later.⁹

Returning the Deposit

You have 21 days after the tenancy ends to either return the full deposit or mail an itemized written statement explaining each deduction. The 21-day clock starts on different dates depending on how the tenancy ended:

Normal move-out: the date the rental agreement terminates.
Early departure or eviction before the lease ends: the lease termination date, or the date a new tenant’s tenancy begins if you re-rent sooner.
Holdover tenant: the date you learn the tenant has vacated, or the date the sheriff removes them.

What You Can Deduct

You can withhold only what is reasonably necessary to cover tenant-caused damage beyond normal wear and tear, unpaid rent, unpaid utility charges the tenant owed under the lease, and government-owned utility charges that became your liability because the tenant did not pay.¹⁰ Routine painting or carpet cleaning is not deductible unless you are repairing actual tenant-caused damage. Intentionally inflating a claim against a deposit can trigger double damages plus attorney fees.

If you want to deduct for anything beyond the standard categories, those terms must appear in a separate document titled “NONSTANDARD RENTAL PROVISIONS,” and you must specifically discuss each one with the tenant before signing.⁹

Entering the Unit After the Tenant Moves In

Once a tenant is in, you cannot walk in whenever you want. Wisconsin limits entry to inspections, repairs, and showings to prospective tenants or purchasers. You must give at least 12 hours of advance notice and enter only at reasonable times. The tenant can agree to a shorter notice period, but only after you tell them you want to enter.¹¹

Three exceptions apply: the tenant consents to entry in advance, there is a health or safety emergency, or the tenant is absent and you reasonably believe entry is necessary to protect the property from damage. When you enter, announce yourself and identify yourself if asked. A lease clause that tries to bypass these rules is void unless it qualifies as a properly disclosed nonstandard rental provision.

Ending a Tenancy

Wisconsin’s termination notice periods are shorter than many states, but they are precise. A defective notice gets your eviction case thrown out.

For nonpayment of rent in a month-to-month, week-to-week, or year-long lease, you give the tenant a written notice allowing at least five days to pay or vacate. If the tenant pays within five days, the tenancy continues. If the same tenant defaults on rent a second time within one year after receiving a five-day notice, you can give a 14-day unconditional notice to vacate with no chance to cure.¹² Leases longer than one year give the tenant at least 30 days to pay and let them avoid termination by taking reasonable steps to fix the default promptly.¹³

For non-rent violations by a month-to-month tenant, a five-day cure-or-quit notice applies the first time, escalating to a 14-day unconditional notice if the tenant violates again within a year. The same five-then-14 pattern applies to tenants under leases of one year or less.

If the notice period runs out without compliance, you file a summons and complaint in circuit court under Wisconsin’s small-claims eviction procedure in Chapter 799.¹⁴ Only a sheriff can physically remove a tenant. Changing the locks, shutting off utilities, or moving a tenant’s belongings out without a court order is an illegal self-help eviction under ATCP 134.09(7), and a tenant can sue for double their actual damages plus court costs and attorney fees.¹⁵ No matter how frustrating a tenant situation becomes, the court process is the only legal path.

Reporting Rental Income to the IRS

Rental income is taxable, and the IRS expects you to report it on Schedule E of Form 1040.¹⁶ You can deduct mortgage interest, property taxes, insurance premiums, advertising, property management fees, repairs, cleaning, and legal or professional fees, usually in the year you pay them.¹⁷

Repairs and improvements are treated differently. A repair keeps the property in its current working condition and is fully deductible the year you pay it — fixing a faucet, patching drywall, replacing a broken window. An improvement adds value, extends the property’s useful life, or adapts it to a new use, and must be depreciated instead: a new roof, a deck addition, a garage conversion. The cost of the building itself (not the land) is depreciated over 27.5 years starting when the property is placed in service, and depreciation is mandatory, not optional. When you eventually sell, the IRS recaptures the depreciation you claimed, so keep thorough records from the first year.¹⁷

What It Costs to Get This Wrong

The penalty structure in ATCP 134 applies across almost everything above. A tenant who suffers a monetary loss from any violation of the chapter can sue for double that loss plus court costs and reasonable attorney fees, and the state can also prosecute.¹⁸ A $1,500 security deposit dispute can quickly become a $3,000 judgment with several thousand more in legal fees on top. For a landlord with one or two units, that is a year of profit.

The protection is straightforward: hit the disclosure timelines, use a lease without prohibited provisions, document the unit’s condition at move-in and move-out, give proper notice before entry, and never shortcut the eviction process. Do those things and the Wisconsin landlord rules are workable. Skip them and the double-damages math catches up fast.
