Wisconsin landlord heat requirements: what the law says

Last updated 2026-07-26

What does Wisconsin law actually require for rental heat?

Wisconsin doesn't have a single "heat law" the way some cities do. The core rule sits inside the state's landlord-tenant trade practice code, Wis. Admin. Code ATCP 134.04(2), which covers habitability generally. The relevant standard most practitioners point to requires that heating facilities be capable of maintaining a minimum room temperature, commonly cited as 67°F, in each habitable room during the heating season, when the landlord supplies the heat. The exact number and season dates get confirmed at the local level because many Wisconsin cities layer their own housing codes on top of the state floor. Madison's rental housing code, for example, sets its own minimum temperature and season window under its municipal code. If you own units in Madison, Milwaukee, Green Bay, or another licensed rental city, check that city's rental housing or building code section directly, because it can be stricter than the state default. The practical split is this: if you (the landlord) provide the furnace, boiler, or building heat system, you're on the hook for keeping it capable of hitting the minimum temperature. If the tenant has their own separate heat source they pay for and control, like a space heater plugged into their own outlet with no landlord-supplied system, the calculus changes and the duty can shift. Always confirm which situation applies to your unit before assuming either way ^[1][2].

What temperature must a Wisconsin landlord keep the apartment at?

The number landlords hear most often is 67°F as the minimum a rental unit's heating system must be capable of maintaining in habitable rooms during cold months. This comes from the general habitability standard under Wisconsin's landlord-tenant trade practices rule, ATCP 134.04, which requires landlords to maintain the structural elements and building systems, including heat, in a condition that doesn't create a health or safety threat to tenants ^[1]. Some cities set their own explicit number that's a degree or two different, and some spell out exact clock hours (for example, a higher daytime minimum and a lower overnight minimum). Because that variance is real and changes over time, don't rely on a number you read online for your specific city. Pull the actual housing code section your city rental inspector enforces and confirm the number and the season dates (heating season typically runs roughly October through May in Wisconsin, but again, confirm with your city). A quick gut check: if a tenant calls in January saying their apartment reads 58°F on a thermometer and your furnace is the building's only heat source, that's very likely a code violation regardless of which specific city ordinance applies. Get a technician out same day or next day. Waiting a week is how a habitability complaint becomes a rent-withholding case or a fine from city inspection staff.

Who pays for heat, the landlord or the tenant, in Wisconsin?

It depends entirely on what the lease says and who controls the equipment. Wisconsin law doesn't force landlords to include heat in rent. Plenty of Wisconsin leases pass heat cost through to the tenant, especially in single-family rentals or duplexes with separate furnaces and separate utility meters. What the law does require, per ATCP 134.04, is that whoever's system supplies the heat, that system has to be capable of reaching the minimum temperature. If you supply a working furnace but the tenant's gas account lapses because they didn't pay the bill, that's a different problem than your furnace being broken. Document which scenario you're in. If your lease requires the tenant to keep utilities active and they don't, that's a lease violation on their end, not a habitability failure on yours, though you still can't retaliate or shut off heat yourself to pressure them. Self-help shutoffs are risky territory. Wisconsin's tenant protection statute, Wis. Stat. § 704.45, and related consumer protection rules generally treat landlord-caused utility shutoffs as prohibited practices when done to force a tenant out or punish them, separate from any habitability heat claim ^[3]. Never cut heat, water, or electricity yourself to deal with a nonpaying or difficult tenant. Use the eviction process instead.

What happens if a landlord doesn't fix a broken furnace in Wisconsin?

A few things can happen, and none of them are good if you drag your feet. First, tenants can report the issue to the city building or health inspection department. Cities with rental licensing programs, like Madison or Milwaukee, typically have a code enforcement track where a broken heat complaint triggers an inspection within days, not weeks, especially in cold months. Second, under Wisconsin law a tenant may have remedies including rent abatement, the right to arrange repairs and deduct the cost from rent (subject to specific notice and cost limits under local ordinance or lease terms), or in serious cases, a claim that the unit is uninhabitable. Wisconsin doesn't have one uniform statewide repair-and-deduct statute for every scenario, so how this plays out often depends on your city's housing code and your lease language. Confirm the specific remedy framework with your city's tenant resources office or a landlord-tenant attorney before assuming either direction. Third, if a city inspector issues a violation notice for inadequate heat and you don't fix it by the deadline in that notice, you're looking at a citation and a re-inspection fee, and if it drags on, daily fines are possible in some municipal codes. This is exactly the kind of thing that turns a five-hundred-dollar furnace repair into a two-thousand-dollar mess once fines, legal notices, and a possible tenant relocation get involved. Fix heat problems fast. It's the cheapest option every time.

How much notice does a landlord have to give before entering to fix heat?

Wisconsin statute Wis. Stat. § 704.05(2) generally requires landlords to give advance notice, commonly at least 12 hours, before entering a rental unit for repairs, inspections, or showings, except in emergencies ^[4]. A furnace that's completely dead in January with tenants reporting dangerously low indoor temperatures reasonably qualifies as an emergency, which allows entry without the standard advance notice, though showing up unannounced should still be a last resort and you should try to reach the tenant first. For routine, non-emergency heat maintenance, like an annual furnace inspection or a scheduled filter change, give the standard notice window and put it in writing (text or email works, and it creates a paper trail). Many Wisconsin leases specify a longer notice period than the statutory minimum, so check your own lease language too, because you're bound by whichever is more protective of the tenant if your lease promises more than the statute requires. Documenting entry notices matters more than people think. If a tenant later disputes an inspection or claims you entered without proper notice, a dated text message or email showing you gave 12+ hours' notice is your best defense.

What can a landlord look at during a rental inspection?

During a routine or city-mandated inspection, a landlord (or the city inspector, if it's a licensing inspection) can generally check the visible condition of the unit: smoke and carbon monoxide detectors, electrical outlets and panels, plumbing fixtures for leaks, window and door locks, heating system function, water heater condition, and signs of pest infestation or mold. Inspectors are typically checking against a written municipal housing code checklist, and in licensed rental cities that checklist is a public document you can request in advance from the building inspection office. What a landlord or inspector generally cannot do is search through a tenant's personal belongings, closets full of the tenant's property, or private papers, unless there's a specific safety reason tied to a reported problem (like checking behind a couch for a suspected gas leak source). The inspection is about the property's condition and code compliance, not a general audit of how the tenant lives. For a city-mandated rental licensing inspection specifically, most Wisconsin cities require the landlord to schedule it, be present or have a representative present, and give tenants advance notice consistent with Wis. Stat. § 704.05(2). If you're prepping for a first-time city rental license inspection, building your own pre-inspection checklist from the city's published code, room by room, catches most of the easy violations (missing detector, torn screen, non-functioning outlet cover) before the inspector ever walks in. This is the exact prep work covered in our $79 City Rental License & Inspection Prep Packet, built around the checklist categories cities actually use.

Who is responsible for a rental walk-through inspection, and does it differ by state?

In most states, including Wisconsin and California, the landlord is responsible for scheduling and conducting the move-in and move-out walk-through inspection, and for documenting the unit's condition with photos or a written checklist. California actually has a specific statutory process: California Civil Code § 1950.5(f) requires landlords to offer tenants an initial move-out inspection before the final one, giving tenants a chance to fix deficiencies before final deductions from a security deposit are calculated ^[5]. Wisconsin doesn't have that exact statutory two-step inspection process, but the same practical logic applies. A landlord who wants to withhold part of a security deposit under Wis. Stat. § 704.28 needs to be able to show the unit's condition at move-in versus move-out, and a documented walk-through with tenant sign-off is the strongest evidence you can have ^[6]. Skipping the move-in walk-through is one of the most common mistakes new landlords make, and it's the reason deposit disputes end up in small claims court. Whether you're in Wisconsin, California, or anywhere else, do the walk-through yourself (or have a property manager do it), use a written form, take dated photos, and get the tenant's signature if they're willing. If a tenant refuses to participate, document that refusal too.

What is landlording, and what is a landlord, exactly?

A landlord is a person or entity that owns residential or commercial property and rents it to someone else (the tenant) in exchange for periodic payment, usually monthly rent. Landlording is the ongoing work of managing that relationship: collecting rent, maintaining the property, handling repairs, following state and local landlord-tenant law, screening new tenants, and managing lease renewals or terminations. It sounds simple until you're doing it. A landlord with even one unit is legally on the hook for habitability standards (heat, water, working locks, structural safety), fair housing compliance under the federal Fair Housing Act, security deposit handling rules specific to their state, and increasingly, local rental registration or licensing rules if their city requires it. None of that is optional once you have a paying tenant in a unit you own. Some landlords self-manage everything. Others hire a property manager to handle day-to-day landlording work (maintenance calls, rent collection, lease enforcement) while the landlord keeps ownership and final decision-making. Either way, the legal responsibilities described in this article, heat, habitability, entry notice, inspections, attach to the property owner regardless of who's doing the daily management.

How do you become a landlord, step by step?

Becoming a landlord starts with owning (or having legal authority to rent, if you're subletting under a master lease with permission) a residential property, then getting it ready to legally rent out. The rough order most new landlords follow: 1. Confirm the property meets local zoning and occupancy rules for rental use. Some cities restrict rentals in certain zones or require a special permit for renting out a single-family home. 2. Check whether your city requires rental registration or a rental license before you can legally lease the unit. This is the step most new landlords miss entirely, and it's the one that generates the fines this site covers. 3. Get the unit inspection-ready: working smoke and CO detectors, functioning heat that meets the minimum temperature standard discussed above, no obvious code violations. 4. Set your rent and screen applicants consistent with fair housing law (you can't discriminate based on race, color, national origin, religion, sex, familial status, or disability under 42 U.S.C. § 3604) ^[7]. 5. Draft a lease that complies with your state's landlord-tenant statute (Wisconsin's is chapter 704 of the Wisconsin Statutes) ^[4]. 6. Collect the security deposit within your state's legal limits and handle it per your state's deposit statute. 7. Get renters insurance requirements sorted (see the next section) and confirm your own landlord insurance policy covers the property as a rental, not an owner-occupied home. Skipping step 2, the licensing check, is the single most expensive mistake in this whole list, because unlicensed rental fines in some Wisconsin cities compound the longer you go without fixing it.

Why do landlords require renters insurance?

Landlords require renters insurance mainly to cover the tenant's personal belongings and personal liability, not the building itself. Your landlord insurance policy covers the structure, but it typically won't reimburse a tenant if their laptop, furniture, or clothes are destroyed in a fire, burst pipe, or theft. Requiring renters insurance shifts that risk off the landlord's dispute plate entirely: if a pipe bursts and ruins the tenant's belongings, their renters insurance handles it, not a claim against you. The liability piece matters just as much. If a tenant's dog bites a visitor, or a guest slips on a wet floor inside the tenant's unit, renters insurance liability coverage (typically included with a standard policy, often with a baseline like $100,000 in liability coverage) can cover the claim instead of it becoming a lawsuit against the landlord. That's a real cost-avoidance move, more than paperwork. Wisconsin law doesn't require renters insurance statewide, but landlords are legally allowed to require it as a lease condition in most states, including Wisconsin, as long as the requirement is applied consistently to all tenants (never selectively, which could raise fair housing concerns). Many landlords write it into the lease as a condition of tenancy and require proof of an active policy before move-in and at each renewal.

What rights do tenants have if there's no written lease?

A tenant without a written lease still has real legal rights. In Wisconsin, an oral or implied rental agreement generally creates a month-to-month tenancy, and the tenant still gets the protections under Wisconsin Statutes chapter 704, including the habitability standards under ATCP 134, proper notice before entry under § 704.05(2), and proper notice before termination ^[4]. For month-to-month tenancies without a lease, Wisconsin generally requires at least 28 days' written notice to terminate the tenancy, though this can vary based on how rent is paid and specific lease history, so confirm the exact notice period that applies to your situation before sending anything. A tenant paying rent and being accepted by the landlord, even with nothing signed, has an implied agreement that courts will treat seriously. What a lease-free tenant does lose out on is the specificity a written lease provides: agreed rent amount in writing, specific rules about guests or pets, and clear renewal terms. That ambiguity cuts both ways and tends to cause more disputes, not fewer, which is exactly why every landlord, even one renting to a family friend, should use a written lease.

What can't a landlord do (using Ohio as a comparison point)?

Since Wisconsin landlords sometimes compare notes with out-of-state peers or manage properties in more than one state, it helps to know how another state's rules line up. Ohio's landlord-tenant law, Ohio Revised Code § 5321.04, requires landlords to keep the premises in a fit and habitable condition, comply with building and housing codes, and maintain electrical, plumbing, and heating systems in good working order . Ohio law, like Wisconsin's, prohibits landlords from shutting off utilities, changing locks, or removing a tenant's belongings to force them out without going through the formal eviction process (a self-help eviction), a practice sometimes called an illegal lockout . Ohio also restricts retaliatory conduct: a landlord generally cannot raise rent, decrease services, or start eviction proceedings in retaliation for a tenant reporting a code violation or joining a tenant organization, under Ohio Rev. Code § 5321.02 . Wisconsin has parallel protections against retaliatory eviction under Wis. Stat. § 704.45 ^[3]. The throughline across every state, Wisconsin, Ohio, California, wherever, is the same: landlords can't take unilateral, punitive, or unsafe action outside the legal eviction and code enforcement process, no matter how frustrated they get with a nonpaying or difficult tenant. Every shortcut around that process (shutoff, lockout, seizing belongings) tends to create bigger legal and financial exposure than just following the process, slow as it is.

How does Wisconsin's heat rule compare to other cold-weather states?

Wisconsin (state floor)	~67°F (habitable rooms, landlord-supplied heat)	Not fixed statewide; confirm with city	Wis. Admin. Code ATCP 134.04 [1]
Chicago, IL	68°F daytime (8:30am-10:30pm), 66°F overnight	Sept 15 - June 1	Chicago Municipal Code 5-12-140
New York City, NY	68°F daytime, 62°F overnight	Oct 1 - May 31	NYC Admin. Code § 27-2029
Minneapolis, MN	68°F	Oct 1 - Apr 30	Minneapolis Code of Ordinances Ch. 244	The pattern across all of these: a daytime minimum somewhere in the high 60s, a defined heating season roughly October through May, and enforcement handled through the local building or housing inspection department, not the state. If you own property in more than one Wisconsin city, or across state lines, don't assume the number and dates transfer from one city to the next. Pull each city's actual code section before winter.

Wisconsin's approach (a general habitability rule under ATCP 134.04 rather than one specific statewide statute naming an exact degree and date range) is actually looser on paper than some neighboring states, though local ordinances often fill that gap. Here's a rough comparison of how a few cold-climate jurisdictions structure their heat rules. | Jurisdiction | Minimum temp cited | Heating season | Primary source |

How do city rental licensing and inspection rules interact with the state heat rule?

Here's the layering most new landlords don't expect: the state habitability rule (ATCP 134.04) sets a floor that applies everywhere in Wisconsin, but if your city requires a rental license or registration, that city's own housing code inspection checklist is usually what actually gets enforced against you, and it can set stricter numbers or add extra requirements like carbon monoxide detector placement near sleeping areas, working thermostats, or specific furnace maintenance records. This is exactly why a landlord who's fine under the general state standard can still fail a city inspection: the city's checklist asks for more. If you're bringing a property up to code for a first rental license application, or dealing with a violation notice tied to heat, treat the city's specific written checklist as the actual test you need to pass, and treat the state rule as the background law that backs it up. Before your next scheduled inspection or license renewal, pull your specific city's rental housing code section (most Wisconsin cities publish it on their building inspection or health department page) and walk your unit against it room by room. That single hour of prep, checking detector placement, testing the furnace, confirming thermostat function, catches most of what turns into fines later. If you'd rather not build that checklist from scratch for each property, our $79 City Rental License & Inspection Prep Packet organizes the common inspection categories cities use so you're not starting cold.

Frequently asked questions

What temperature is a landlord legally required to keep an apartment in Wisconsin?

Wisconsin's general habitability standard under Wis. Admin. Code ATCP 134.04 is commonly interpreted as requiring heating systems capable of maintaining around 67°F in habitable rooms during the heating season, when the landlord supplies the heat. Many cities set their own specific number and season dates, so confirm the exact figure with your city's rental housing or building inspection office.

Can a Wisconsin landlord shut off heat to force a tenant out?

No. Wisconsin Statute § 704.45 generally prohibits landlords from shutting off utilities, changing locks, or removing belongings to force a tenant out outside the formal eviction process. This applies regardless of whether rent is unpaid or the tenant is causing other problems. Use the eviction process, not a utility shutoff.

How much notice does a landlord have to give before entering a Wisconsin rental?

Wisconsin Statute § 704.05(2) generally requires at least 12 hours' advance notice before entry for non-emergency purposes like repairs or inspections. Emergencies, like a completely failed furnace in freezing weather, can allow faster entry, but try to reach the tenant first and document the situation.

What can a landlord look at during a rental inspection?

A landlord or city inspector can generally check smoke and CO detectors, electrical and plumbing systems, heating equipment, locks, windows, and signs of pest or mold problems, against the local housing code checklist. They generally cannot search a tenant's personal belongings or private papers without a specific safety reason.

Who is responsible for a rental property walk-through inspection?

The landlord is generally responsible for scheduling and documenting move-in and move-out walk-through inspections. California Civil Code § 1950.5(f) specifically requires landlords to offer an initial move-out inspection before the final deposit deduction is calculated. Wisconsin doesn't have that exact statute, but documented walk-throughs are still the landlord's best evidence in a deposit dispute.

What is landlording?

Landlording is the ongoing work of owning and managing a rental property: collecting rent, handling repairs, following habitability and safety codes, screening tenants, and managing lease terms and renewals. It applies whether you self-manage or hire a property manager, since legal responsibility stays with the property owner.

What is a landlord?

A landlord is the owner of residential or commercial property who rents it to a tenant in exchange for periodic payment. Landlords carry legal responsibilities for habitability, safety, fair housing compliance, security deposit handling, and, in many cities, rental registration or licensing requirements.

How do you become a landlord?

Confirm your property's zoning allows rental use, check for any local rental licensing or registration requirement, get the unit inspection-ready (working heat, detectors, no code violations), screen tenants consistent with fair housing law, use a written lease compliant with your state's landlord-tenant statute, and handle the security deposit within legal limits.

What rights do tenants have without a written lease?

A tenant without a written lease in Wisconsin generally has a month-to-month tenancy with the same core protections: habitability standards, proper notice before entry, and proper notice before termination (generally at least 28 days for month-to-month tenancies under Wisconsin law). Confirm exact notice periods for your specific situation.

Why do landlords require renters insurance?

Renters insurance covers the tenant's personal belongings and personal liability, which the landlord's own property insurance doesn't cover. It shifts risk for tenant property loss and liability claims (like a guest injury) away from the landlord, and landlords can generally require it as a lease condition as long as it's applied consistently.

What can't a landlord do in Ohio?

Under Ohio Revised Code § 5321.04, a landlord must keep the unit habitable and maintain heating, electrical, and plumbing systems. Ohio law also prohibits self-help evictions (utility shutoffs, lockouts, removing belongings) and retaliatory actions like rent increases after a tenant reports a code violation, under Ohio Rev. Code § 5321.02.

Does Wisconsin have a statewide law setting an exact minimum heat temperature and date range?

Not a single specific statute naming one universal number and date range for the whole state. The general standard comes from Wis. Admin. Code ATCP 134.04's habitability rule, commonly cited around 67°F, and many Wisconsin cities add their own specific numbers and heating season dates through local housing codes.

Can a tenant withhold rent if the landlord won't fix the heat in Wisconsin?

Depending on your city's code and the lease terms, tenants may have remedies including rent abatement or repair-and-deduct options, but Wisconsin doesn't have one blanket statewide repair-and-deduct statute covering every case. Confirm the applicable remedy with your city's housing office or an attorney, since acting on the wrong assumption can create legal risk for either side.

What happens if a Wisconsin landlord gets a heat-related code violation notice?

You'll typically get a deadline to fix the issue and schedule a re-inspection. Missing that deadline can lead to a citation, re-inspection fees, and in some municipal codes, daily fines that accumulate the longer the violation stays open. Fixing heat issues quickly, ideally same-day or next-day, is almost always cheaper than the fines.
