Wisconsin landlord-tenant utility laws require landlords to disclose who pays for water, heat, and electricity before a lease is signed, forbid landlords from shutting off service to force a tenant out, and obligate landlords to keep heating, plumbing, and electrical systems in working order throughout the tenancy. The rules live mainly in Wisconsin Administrative Code ATCP 134 and Wisconsin Statutes Chapter 704, with additional protections from the Public Service Commission and the municipal utility statute.
What the Landlord Must Disclose Before You Sign
If water, heat, or electricity charges are not included in the rent, the landlord has to tell you so before you enter a rental agreement or hand over any earnest money or security deposit.1Legal Information Institute. Wisconsin Administrative Code ATCP 134.04 – Disclosure Requirements A landlord who skips this step cannot later claim you agreed to cover those costs, which usually leaves the landlord stuck with bills meant for the tenant.
When one meter covers more than one apartment, or covers common areas like hallways, laundry rooms, or parking lot lighting, the landlord has to disclose the shared arrangement and spell out the formula used to divide the bill.1Legal Information Institute. Wisconsin Administrative Code ATCP 134.04 – Disclosure Requirements The split might be by square footage, by number of occupants, or an equal share. If you discover after moving in that your meter runs a shared hallway or another unit, and nothing was disclosed, you have grounds to complain to the Department of Agriculture, Trade and Consumer Protection.
Wisconsin does not cap late fees on utility charges billed through the landlord. The fee has to be “reasonable,” and signed lease terms usually hold up unless the amount is clearly excessive.
The 67-Degree Heating Standard
Every residential rental in Wisconsin must have heating equipment capable of maintaining at least 67°F in all living areas during every season the unit is occupied.2Wisconsin State Legislature. Wisconsin Administrative Code ATCP 134.04(2)(b) – Disclosure Requirements Temperature is measured at the center of each room, midway between floor and ceiling. The rule runs year-round, not just in winter.
This is a habitability standard, and a lease clause trying to waive it is void and unenforceable.3Wisconsin State Legislature. Wisconsin Statutes 704.44 – Residential Rental Agreement That Contains Certain Provisions Is Void If a landlord knows before renting that the heating system cannot meet the 67°F threshold, that deficiency has to be disclosed to the prospective tenant as a condition affecting habitability.2Wisconsin State Legislature. Wisconsin Administrative Code ATCP 134.04(2)(b) – Disclosure Requirements
Shutting Off Utilities Is Illegal
A Wisconsin landlord cannot exclude, forcibly evict, or constructively evict a tenant except through formal judicial eviction under Chapter 799.4Wisconsin State Legislature. Wisconsin Administrative Code ATCP 134.09 – Prohibited Practices Disconnecting utility services counts as constructive eviction, right alongside changing the locks or removing doors. Months of unpaid rent does not change this: the landlord has to go to court, not to the breaker panel.
A separate rule targets retaliation. A landlord cannot terminate or substantially reduce heat, water, or electricity because a tenant reported a code violation to a government agency, organized or joined a tenants’ union, or asserted any right granted under state or local law.5Wisconsin State Legislature. Wisconsin Administrative Code ATCP 134.09(5) – Retaliatory Eviction The statute goes further: in a residential tenancy, a landlord cannot increase rent, decrease services, bring an eviction, or refuse to renew if the move was motivated by retaliation for a good-faith habitability complaint.6Wisconsin State Legislature. Wisconsin Statutes 704.45 – Retaliatory Conduct in Residential Tenancies Prohibited
Keeping Utility Systems Working
The landlord’s duty does not end at move-in. Under state law, landlords must keep in reasonable repair all equipment necessary to supply services they agreed to provide, including heat, water, and air conditioning. They also must make necessary structural repairs and repair or replace plumbing, electrical wiring, and machinery that is no longer in reasonable working condition.7Wisconsin State Legislature. Wisconsin Statutes 704.07 – Repairs and Maintenance of Premises
If a broken furnace or burst water line makes the unit unlivable, the tenant has two choices under the statute. One, move out without further rent liability; the landlord has to refund any prepaid rent covering time after the unit became unlivable. Two, stay and pay reduced rent, abated in proportion to how much normal use of the unit has been lost.7Wisconsin State Legislature. Wisconsin Statutes 704.07 – Repairs and Maintenance of Premises A tenant who stays cannot withhold rent entirely, but partial abatement is built into the law. These remedies do not apply when the tenant’s own negligence caused the problem.
Winter Shutoff Protection From the Utility Company
From November 1 through April 15 each year, Wisconsin utilities are prohibited from disconnecting residential service used for home heating because of nonpayment.8Wisconsin State Legislature. Wisconsin Administrative Code PSC 113.0304 – Cold Weather Disconnection The moratorium limits what the utility company can do; it does not create a separate rule for landlords, who are already barred from cutting service year-round.
The protection is not absolute. Utilities can still disconnect households whose gross quarterly income exceeds 250% of the federal poverty guidelines, provided a shutoff would not endanger someone’s health or safety due to age, disability, or being very young.8Wisconsin State Legislature. Wisconsin Administrative Code PSC 113.0304 – Cold Weather Disconnection Once April 15 passes, utilities can resume disconnection for overdue accounts, so a tenant who fell behind during winter should line up a payment plan before the moratorium ends.
Who Pays When a Tenant Skips a Municipal Utility Bill
Where the water or sewer service comes from a government-owned utility, unpaid charges can become a lien on the rental property itself, including penalties.9Wisconsin State Legislature. Wisconsin Statutes 66.0809 – Municipal Utility Charges and Liens The lien attaches to the real estate, not to the tenant, so the landlord ultimately pays for service the tenant consumed.
Municipal utilities can set different deposit and collection practices for owners versus tenants. If a landlord gives the utility written notice identifying the occupant as a tenant, the utility must notify the landlord within 14 days of any past-due charges before placing them against the property.9Wisconsin State Legislature. Wisconsin Statutes 66.0809 – Municipal Utility Charges and Liens Any landlord with property on municipal water or sewer should register with the utility to receive those warnings.
Security Deposit Deductions for Unpaid Utilities
At move-out, a Wisconsin landlord may withhold from the security deposit for two kinds of utility charges. First, utility service the landlord provided but did not include in the rent. Second, charges owed to a government-owned utility, but only to the extent the landlord actually becomes liable for the tenant’s nonpayment.10Wisconsin State Legislature. Wisconsin Statutes 704.28 – Withholding From and Return of Security Deposits A landlord cannot deduct for an unpaid bill from a private utility company where the account sits solely in the tenant’s name and the landlord has no legal liability for it.
The deposit, minus any lawful deductions, has to come back within 21 days after the tenancy ends.10Wisconsin State Legislature. Wisconsin Statutes 704.28 – Withholding From and Return of Security Deposits Deductions have to be itemized. A landlord who misses the 21-day window risks losing the right to withhold at all.
Help Paying Heating Bills
The Wisconsin Home Energy Assistance Program (WHEAP) helps eligible households pay heating costs. It runs October 1 through September 30, and eligibility is set at 60% of Wisconsin’s median income. For the 2025–2026 program year, income limits range from $38,421 for a single-person household up to $101,965 for a household of eight.11Wisconsin.Gov. Wisconsin Home Energy Assistance Program The ceilings are higher than most tenants assume, so apply even if you think you earn too much.
One boundary worth knowing: Wisconsin’s HE+ HVAC emergency furnace repair program serves homeowners who already receive WHEAP, not renters. If your furnace fails, the fix is your landlord’s responsibility under the repair statute, regardless of whether the landlord qualifies for any assistance program.
How to Push Back on a Utility Problem
Start with a written notice to your landlord describing the problem, what you want done, and a reasonable timeframe. Written communication creates a dated record, and both agencies and courts will want to see that you tried to resolve the issue directly first.
If that fails, where you go next depends on who is causing the problem:
- For landlord-tenant disputes, including billing, disclosure failures, shutoffs, and shared meter issues, file a complaint with the Wisconsin Department of Agriculture, Trade and Consumer Protection, which enforces ATCP 134. DATCP uses a landlord-tenant complaint form separate from its general consumer form.12Wisconsin Department of Agriculture, Trade and Consumer Protection. File a Consumer Complaint
- For disputes with the utility company itself over service quality, disconnection, or billing, contact the Public Service Commission of Wisconsin. You have to try to resolve the dispute with the utility first; if that fails, the PSC can step in.13Public Service Commission of Wisconsin. File a Utility Complaint
- For financial claims up to $10,000, including overcharged utility costs, unreturned security deposits, or damages from an illegal shutoff, small claims court is faster and cheaper than a full civil case.14Wisconsin Court System. Small Claims
Hold onto your lease, every utility bill from the disputed period, any messages exchanged with the landlord, and records of repair requests. Attach copies to any complaint. Utility disputes are won on documentation, and saving everything from day one is the most useful thing a tenant can do.
