Pet Deposits, Pet Rent & ESA Rules in Wisconsin 2026
State pet-deposit treatment, federal Fair Housing Act assistance-animal rules, and what Wisconsin landlords can and cannot ask.
In Wisconsin, your freedom to set pet policies stops where disability law begins. You can ban pets outright, cap their number, charge pet rent, and collect a pet deposit, but none of that applies to service animals or emotional support animals (ESAs), which the law treats as reasonable accommodations, not pets. The controlling state authority is the Wisconsin Open Housing Law, Wis. Stat. § 106.50, layered on top of the federal Fair Housing Act. Wisconsin is one of the few states that wrote ESA-specific rules directly into its housing statute, including a documentation standard and a $500 minimum forfeiture for faking a disability. This page explains where your ordinary pet rules apply, where they must yield, and how to handle accommodation requests without stepping into a discrimination claim.
How Wisconsin Treats Pet Deposits
Wisconsin has no statutory cap on the security deposit or pet deposit. ATCP 134.06 governs return procedures but sets no maximum.
Ordinary pets: your rules control
Nothing in Wisconsin or federal law forces you to allow pets. For an ordinary pet, a dog, cat, or other companion animal with no disability connection, you set the terms. You may prohibit pets entirely, restrict breed, size, or number, and charge a refundable pet deposit, non-refundable pet fee, or monthly pet rent. Those charges are separate from the tenant's security deposit and should be spelled out in the lease or a pet addendum. The one thing to keep clean: a pet policy cannot be a backdoor way to refuse a service animal or ESA. If you advertise “no pets” but a qualified applicant needs an assistance animal, the accommodation rules below override your pet ban for that animal.
Service animals vs. emotional support animals
The two categories are governed differently, and treating them the same is a common landlord mistake. A service animal under the Americans with Disabilities Act is a dog (or in limited cases a miniature horse) individually trained to do work or perform tasks for a person with a disability, guiding, alerting, retrieving, interrupting a seizure. An emotional support animal, defined in Wis. Stat. § 106.50(2r), is an animal that provides comfort, companionship, or emotional support but is not trained to perform disability-related tasks. In housing, both qualify as reasonable accommodations under the federal Fair Housing Act and § 106.50. The practical difference is documentation: when a person's disability and a trained service dog's work are obvious, you generally cannot demand paperwork; for an ESA, Wisconsin expressly lets you request reliable documentation, as explained below.
No pet fees, deposits, or breed limits on assistance animals
Because service animals and ESAs are not pets, you may not charge a pet fee, pet deposit, or pet rent for them, and you may not apply breed, size, or weight restrictions to them. This holds even in a strict no-pets building. A tenant does, however, remain fully responsible for the animal's conduct. Wis. Stat. § 106.50(2r)(br)3 states that a person who keeps an ESA “shall accept liability for sanitation with respect to, and damage to the premises caused by, the animal.” So while you cannot front-load a special deposit, you can apply the tenant's ordinary security deposit and pursue them personally for animal-caused damage beyond normal wear, chewed trim, urine-soaked flooring, yard destruction, exactly as you would for any tenant-caused damage.
What documentation you can request
For a service animal whose handler's disability and the dog's task are apparent, asking for proof is generally off-limits. Where the need is not obvious, follow HUD's two-question approach: you may ask whether the person has a disability-related need for the animal and what work or task it performs, you may not ask about the diagnosis or demand medical records.
For an ESA, Wisconsin gives you a clearer footing. Under § 106.50(2r)(br)2, you may request reliable documentation that the individual has a disability and reliable documentation of the disability-related need for the animal from a licensed health professional, a physician, psychologist, social worker, or other health professional licensed or certified in Wisconsin and acting within the scope of that license. That standard lets you reject a pay-per-download “ESA certificate” from an out-of-state website mill that reflects no real provider relationship. Request the documentation in writing, keep it confidential, and respond to a complete request promptly; unreasonable delay can itself be treated as a refusal to accommodate.
Misrepresentation and the $500 forfeiture
Wisconsin backs its ESA rules with a penalty aimed at fraud. Under § 106.50(2r)(br)5, a person who, for the purpose of obtaining housing, intentionally misrepresents that they have a disability or misrepresents the need for an ESA shall forfeit not less than $500. The same minimum forfeiture applies under § 106.50(2r)(br)6 to a licensed health professional who misrepresents a patient's disability or need for an ESA to help that patient obtain housing. This is a real deterrent against fake letters, but it does not license you to interrogate every applicant, the safe path is to request proper documentation, evaluate it in good faith, and grant legitimate requests. Note a separate proposal, 2025 AB366 / SB327, would penalize falsely claiming a service animal in a public place of accommodation; it is not yet law and concerns public access, not housing.
The Cost of Mishandling a Wisconsin ESA Request
The most common mistake in Wisconsin ESA cases is responding with a flat denial, "no pets means no pets", instead of engaging in the interactive process. The interactive process is itself a substantive duty. A landlord who refuses to consider the request, demands more documentation than HUD permits, or imposes a pet fee on an accepted assistance animal will lose at HUD even if the underlying accommodation could have been reasonably denied on its merits.

It is written for landlords and property managers and is general information, not legal advice. Statutes and administrative interpretations change, and accommodation disputes turn on specific facts, confirm the current text at the Wisconsin Legislature's statute site and consult a Wisconsin housing attorney before denying an accommodation request or acting on a suspected misrepresentation.
Frequently Asked Questions
Can a Wisconsin landlord charge a pet deposit for an emotional support animal?
No. Service animals and ESAs are treated as reasonable accommodations, not pets, so you may not charge a pet deposit, pet fee, or pet rent for them. You can still hold the tenant's ordinary security deposit and, under Wis. Stat. § 106.50(2r)(br)3, pursue the tenant for any sanitation issues or damage the animal actually causes.
What documentation can I ask for when a tenant requests an ESA?
Under Wis. Stat. § 106.50(2r)(br)2 you may request reliable documentation that the tenant has a disability and reliable documentation of the disability-related need for the animal from a licensed health professional, a physician, psychologist, social worker, or other provider licensed or certified in Wisconsin and acting within their scope. You may not demand the underlying diagnosis or full medical records.
Do I have to accept an online ESA certificate?
Not automatically. Wisconsin's standard requires documentation from a licensed health professional with an actual relationship to the tenant. A generic pay-per-download certificate from a website that reflects no real evaluation does not meet that standard, and you may request compliant documentation before granting the accommodation.
Can I apply breed or weight restrictions to a service animal or ESA?
No. Breed, size, and weight limits are pet-policy tools and cannot be applied to service animals or ESAs. You may address an individual animal only if it poses a direct threat to health or safety or would cause substantial physical damage, based on that specific animal's conduct, not on its breed.
What is the penalty for faking a disability or ESA need in Wisconsin?
A person who intentionally misrepresents a disability or the need for an ESA to obtain housing shall forfeit not less than $500 under Wis. Stat. § 106.50(2r)(br)5. The same minimum forfeiture applies under (br)6 to a licensed health professional who misrepresents a patient's disability or ESA need to help that patient get housing.
Am I still protected if the animal damages my property?
Yes. Wis. Stat. § 106.50(2r)(br)3 makes the tenant responsible for sanitation and for damage the ESA causes. You cannot charge an upfront pet deposit, but you can deduct animal-caused damage beyond normal wear from the security deposit and pursue the tenant for amounts beyond it, just as with any other tenant damage.
Does Wisconsin law override the federal Fair Housing Act?
No, they work together. The federal Fair Housing Act sets the baseline duty to grant reasonable accommodations for assistance animals nationwide. Wis. Stat. § 106.50 mirrors that duty and adds Wisconsin-specific detail, including the licensed-provider documentation standard and the $500 misrepresentation forfeiture. Comply with whichever protection is stronger for the tenant.
