Service animals, emotional-support animals, and reasonable accommodation duties under the federal Fair Housing Act and Wis. Stat. § 106.50.
Wisconsin does not run a separate accessibility regime on top of the federal Fair Housing Act. Instead, the state Open Housing Law, Wis. Stat. 106.50, folds the same two duties every landlord owes into state law: you must allow reasonable modifications and make reasonable accommodations for tenants and applicants with disabilities. The disability protections sit in Wis. Stat. 106.50(2r), and they track the federal baseline under 42 U.S.C. 3604(f) closely enough that a request handled correctly under the FHA is almost always handled correctly under Wisconsin law. The practical difference is enforcement: a Wisconsin tenant can file with the state Equal Rights Division, not just HUD, and the state's own accessible-design cross-reference (Wis. Stat. 101.132) governs newer multifamily buildings.
Adds sexual orientation, marital status, lawful source of income (Wisconsin's analog covers HCV in housing context), age, ancestry.
The single most useful distinction in this area is between an accommodation and a modification, because it controls who writes the check.
A reasonable accommodation is a change to a rule, policy, practice, or service — waiving a no-pets rule for an assistance animal, assigning a reserved parking space near the unit, or accepting a co-signer for an applicant whose income comes from disability benefits. Under Wis. Stat. 106.50(2r)(b)4. and the federal FHA, the landlord absorbs the cost of an accommodation, because the cost is usually just the administrative effort of bending a policy.
A reasonable modification is a physical change to the unit or common areas — grab bars, a ramp, widened doorways, a roll-in shower. Under Wis. Stat. 106.50(2r)(b)3., you must permit the modification, but the statute expressly says it is done “at the expense of a person with a disability.” The tenant pays for the work and for maintaining it. Your obligation is not to fund it — it is not to stand in the way.
Because the tenant is altering your property, Wisconsin lets you protect the asset — within limits. For an interior modification, you may require a written agreement that the tenant will restore the interior to the condition that existed before the change, other than reasonable wear and tear. Where restoration is reasonably likely to be needed, you may also require the tenant to pay a reasonable amount into an interest-bearing escrow account to cover it.
Two hard limits trip up landlords. First, restoration agreements reach interior work only. You cannot demand that a tenant remove an exterior feature such as a wheelchair ramp at the front door — exterior modifications stay. Second, you may not charge extra fees, surcharges, an increased deposit, or require the tenant to buy special liability insurance as a condition of approving a modification or an accommodation. The cost the tenant bears is the cost of the work itself, nothing bolted on.
Neither Wisconsin nor federal law requires magic words — a tenant does not have to say “reasonable accommodation” or cite a statute. Once a tenant links a request to a disability-related need, your duty to engage is triggered. Treat it as a good-faith back-and-forth:
Assistance animals — both service animals and emotional support animals — run through this same accommodation process. They are not pets, so no pet fee, pet deposit, or breed/weight limit applies, though the tenant remains responsible for any actual damage the animal causes.
“Reasonable” is a real qualifier, and a denial is defensible when it rests on the recognized grounds rather than inconvenience:
Document your reasoning and offer an alternative before refusing outright. A denial that skips the interactive process is far harder to defend than one that shows you engaged and explained.
Existing rentals are governed by the permit-and-accommodate rules above. New buildings carry an added design duty. Under Wis. Stat. 106.50(2r)(c), covered multifamily housing must be designed and built to accessible standards, cross-referencing the state building requirements at Wis. Stat. 101.132(2)(a)1.-4. This mirrors the federal FHA rule that covered multifamily housing first occupied after March 13, 1991 meet baseline accessibility features — accessible entrances, usable doors and routes, reinforced bathroom walls, and reachable controls.
Enforcement gives Wisconsin tenants two doors. They may file with the Wisconsin Equal Rights Division (Department of Workforce Development) under Wis. Stat. 106.50, generally within 1 year of the alleged violation, or with HUD under the federal FHA, also within 1 year. Both can investigate, conciliate, and pursue damages. For landlords, the takeaway is simple: a clean, documented interactive process is the cheapest insurance against either forum.
This statute is generally enforced in public-accommodation contexts (restaurants, retail) rather than as part of a landlord-tenant dispute. For housing, the practical landlord defense against a fraudulent ESA claim is to require reliable documentation from a healthcare professional with a therapeutic relationship to the tenant, not to attempt criminal enforcement.
The most common mistake in Wisconsin reasonable-accommodation 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 than HUD permits, or imposes a pet fee on an assistance animal will lose at HUD even if the underlying accommodation could have been reasonably denied.
Reasonable modification (42 U.S.C. § 3604(f)(3)(A)) is a structural change, a grab bar, a ramp, lowered cabinets. The tenant pays. The landlord must permit the modification and may require restoration to original condition at move-out (except for changes that would not significantly affect re-rental). Reasonable accommodation is a change to a rule or policy. The landlord pays no out-of-pocket cost; the cost is administrative. Wisconsin follows the federal rule.

This page summarizes the reasonable accommodation and modification duties that Wisconsin landlords owe under the state Open Housing Law, Wis. Stat. 106.50 (disability provisions at subsection (2r)), read alongside the federal Fair Housing Act at 42 U.S.C. 3604(f). Statutory citations, restoration and escrow rules, the accessible-design cross-reference to Wis. Stat. 101.132, and the 1-year filing window with the Wisconsin Equal Rights Division were verified against the Wisconsin Legislature's statute text and Department of Workforce Development guidance current to 2026. It is general information for rental-housing owners and operators, not legal advice; fact patterns vary, and you should confirm a specific request with the Equal Rights Division, HUD, or Wisconsin counsel before denying it.
The tenant does. Under Wis. Stat. 106.50(2r)(b)3., a physical change like a ramp is a reasonable modification made at the expense of the person with the disability. Your duty is to permit it, not to fund it. And because an exterior ramp is outside the unit, you cannot require the tenant to remove it when they move out.
No. Service animals and emotional support animals are treated as a reasonable accommodation under Wis. Stat. 106.50(2r)(b)4. and the federal FHA, not as pets. No pet fee, pet deposit, or breed or weight restriction applies. The tenant is still liable for any actual damage the animal causes.
Only when the disability or the need is not obvious. In that case you may request reliable disability-related verification that the person has a disability and needs the requested change, usually a letter from a treating professional. You may not ask for a diagnosis, demand medical records, or ask about the nature or severity of the condition.
For interior modifications, yes. You can require a written agreement to restore the interior to its prior condition, other than reasonable wear and tear, and where reasonable you may require funds paid into an interest-bearing escrow account. This does not apply to exterior modifications, which the tenant is not required to remove.
When it would impose an undue financial or administrative burden, fundamentally alter your services, or create a direct threat to health, safety, or property that no alternative can reduce, or when the request is not actually connected to a disability. Denials that skip the interactive process are the hardest to defend.
A Wisconsin tenant can file with the state Equal Rights Division (Department of Workforce Development) under Wis. Stat. 106.50, generally within 1 year, or with HUD under the federal Fair Housing Act, also within 1 year. Both can investigate, conciliate, and award damages.
