✓ Law Verified August 2026
Wisconsin landlord retaliation law exists because rights you cannot safely use are not rights at all. This guide covers the two ugliest moves a landlord can make, punishing you for complaining, and forcing you out without a court, what each one costs the landlord in Wisconsin, and exactly what to do when it happens to you.

Wisconsin Landlord Retaliation and Lockout Law at a Glance
| Retaliation law | Wis. Stat. 704.45 (Retaliatory conduct in residential tenancies prohibited) is the main statute. A second, separate protection sits in the administrative rules: Wis. Admin. Code ATCP 134.09(5) (retaliatory eviction), enforceable through Wis. Stat. 100.20(5) and 704.95. Both are statutory/regulatory — this is not case-law-only protection. |
| Presumption window | NONE. Wisconsin has no fixed day-count presumption. Wis. Stat. 704.45(1) instead uses a but-for test: the tenant wins if a preponderance of the evidence shows the landlord’s action or inaction would not have occurred but for retaliation. Timing still matters as evidence, but no number of days creates an automatic presumption. |
| What retaliation costs the landlord | Wis. Stat. 704.45 itself sets no dollar figure and no statutory multiplier — it makes the retaliatory act prohibited, so many tenants use it as a defense to an eviction filed in retaliation and to block a retaliatory rent increase or service cut. Where the same conduct also violates ATCP 134.09(5), Wis. Stat. 100.20(5) lets a tenant who suffered a pecuniary loss recover twice the amount of that loss, together with costs of suit including reasonable attorney fees. Note the carve-out: under Wis. Stat. 704.45(2) a landlord may still bring an eviction for possession if the tenant has not paid rent, other than a rent increase that sub. (1) prohibited. Criminal prosecution of a 100.20 violation is possible under Wis. Stat. 100.26(3), but that is a state action, not tenant compensation. |
| Lockout law | Wis. Admin. Code ATCP 134.09(7) — “No landlord may exclude, forcibly evict or constructively evict a tenant from a dwelling unit, other than by an eviction procedure specified under ch. 799, Stats.” Related provisions: ATCP 134.09(5) (constructive eviction by cutting heat, water or electricity), ATCP 134.09(4) (landlord may not seize or hold the tenant’s personal property except as specifically allowed), and Wis. Stat. 799 (the only lawful eviction route, executed by the sheriff on a court order). |
| What a lockout costs the landlord | Wisconsin sets no per-day statutory lockout amount and no flat statutory penalty figure. The remedy is Wis. Stat. 100.20(5): a tenant who suffers a pecuniary loss from the ATCP 134.09(7) violation may sue and recover 2 times the actual loss, plus costs of suit including reasonable attorney fees. Recoverable actual loss commonly includes hotel or motel nights, meals out, replacement of property the landlord removed or destroyed, storage, lost wages and moving costs — all doubled. Because attorney fees are shifted to the landlord, many tenants can get a lawyer to take a lockout case they could not otherwise afford. A court may also order the landlord to let you back in; ask your court about emergency relief. |
Recognizing Wisconsin Landlord Retaliation When It Happens
Retaliation rarely announces itself. It looks like a sudden rent increase the month after you called the housing inspector, a non-renewal notice days after you asked for repairs in writing, new rules that only seem to apply to you, or an eviction filing right after you joined other tenants in a complaint.
The law does not require the landlord to admit anything, Wisconsin landlord retaliation cases are won on timing and paper.
That is why the habit that protects you most is boring: put every request and complaint in writing, date it, and keep a copy from day one.
Retaliation law does not make you eviction-proof, and it does not excuse unpaid rent. What it does is take away the landlord’s power to punish you for using rights Wisconsin gave you, and when the timeline shows punishment, judges notice.
What You Are Protected For
Under Wis. Stat. 704.45(1) the landlord may not increase rent, decrease services, bring an eviction action, refuse to renew a lease, or threaten any of those because the tenant: (a) made a good faith complaint about a defect in the premises to an elected public official or a local housing code enforcement agency; (b) complained to the landlord about a violation of Wis.
Stat. 704.07 (repair/maintenance duties) or a local housing code; or (c) exercised a legal right relating to residential tenancies.
ATCP 134.09(5) separately protects a tenant who reported a violation of ch. ATCP 134 or a building or housing code to a governmental authority or filed suit over it, joined or attempted to organize a tenants union or association, or asserted or attempted to assert any right specifically given to tenants under state or local law.
The timing presumption: NONE. Wisconsin has no fixed day-count presumption. Wis. Stat. 704.45(1) instead uses a but-for test: the tenant wins if a preponderance of the evidence shows the landlord’s action or inaction would not have occurred but for retaliation. Timing still matters as evidence, but no number of days creates an automatic presumption.
Locked Out or Utilities Cut? Do This Today
1) Call the local police or sheriff and say clearly that this is an illegal lockout or utility shutoff under ATCP 134.09(7), not a rent dispute; ask for an incident or case number even if the officer will not force the door open.
2) Photograph and video everything the same day — the changed or added lock, your key not working, the removed door or window, a dead meter, missing belongings, the thermostat or a thermometer reading, and any notice the landlord posted.
3) Text or email the landlord in writing demanding immediate restoration of access and services, and keep the sent copy. 4) Go to the clerk of the small claims branch of your county circuit court and ask to file against the landlord for the illegal lockout, and ask the clerk about emergency relief — a temporary restraining order or injunction under Wis. Stat. ch. 813 — to get you back in or restore utilities.
The exact self-help form number the clerk gives you can vary by county, so ask at the counter or check wicourts.gov. 5) File a complaint with DATCP Bureau of Consumer Protection at 800-422-7128 or [email protected]. 6) Call Legal Action of Wisconsin, your local legal aid, or a tenant lawyer — fee-shifting under 100.20(5) means representation is often affordable.
7) Find somewhere safe to stay and keep every receipt; those costs are the loss that gets doubled.
Utility shutoffs: Yes, illegal. ATCP 134.09(5) expressly names “the termination or substantial reduction of heat, water or electricity to the dwelling unit” as a prohibited means of constructive eviction, and shutting off essential services to force a tenant out is also an exclusion/constructive eviction barred by ATCP 134.09(7). Same remedy: under Wis.
Stat. 100.20(5) you may be able to recover 2 times your pecuniary loss plus costs and reasonable attorney fees.
A landlord’s shutoff can also give a tenant grounds to treat the unit as uninhabitable — talk to a tenant lawyer before you stop paying rent or leave.
Whatever the details in Wisconsin, one rule holds everywhere in the country: a landlord cannot be the judge. Changing the locks, hauling your belongings to the curb, or cutting the power to force you out skips the court process every state requires, which is exactly why the law puts money penalties on it.
Do not respond in kind and do not break back in; document everything with photos and timestamps, keep receipts for every night of housing and every meal the lockout forces on you, and let the court hand the landlord the bill.
Ask the court clerk for the emergency form that restores possession, every state has one, most clerks will point you to it the same day, and judges hear these motions fast precisely because the law treats a lockout as an emergency.
How to Respond to Wisconsin Landlord Retaliation
Build a dated paper trail first. Write down the date you complained to the landlord, the building inspector, or the elected official, and keep the inspection report, complaint confirmation, or email.
Then log the landlord’s response — the rent increase notice, the nonrenewal notice, the 5-day or 14-day notice, the service that got cut — with its date, because the gap between the two is the core of your but-for proof under Wis. Stat. 704.45(1).

Send the landlord a short written letter or email stating that you complained about [specific defect] on [date], that Wis. Stat. 704.45 and ATCP 134.09(5) bar retaliation, and that you are asking the action be withdrawn; keep a copy.
If the landlord files an eviction, appear on your return date and raise retaliation as an affirmative defense — do not skip the hearing, since not appearing usually means a default judgment. You may also be able to counterclaim in that same case under Wis.
Stat. 100.20(5) for double your pecuniary loss plus costs and reasonable attorney fees. Keep paying rent into your normal channel unless a lawyer advises otherwise, because Wis. Stat. 704.45(2) lets a landlord evict for nonpayment even where retaliation happened. File a DATCP complaint at 800-422-7128 and check with your court or a tenant lawyer about deadlines.
The Paper Trail Playbook Every Wisconsin Tenant Should Run
Start a single folder, paper or phone, the first day anything feels off. Every repair request goes in writing, even if you also called: a short text or email saying what is broken and when you reported it is enough. Photograph problems with the date visible, save every reply, and after any phone call that matters, send a one-line follow-up confirming what was said.
None of this is aggressive; it is just memory that a court can read.
If pressure starts, write a timeline while events are fresh: the date of your complaint, the date of the landlord’s response, and every step after. Retaliation cases in Wisconsin are decided on exactly this sequence, and the tenant who can hand a judge a clean dated timeline almost always outperforms the one relying on memory.
Keep paying rent the lawful way while the dispute runs, withholding without following the proper procedure hands the landlord the very eviction ground retaliation law took away. And if you feel unsafe at any point, involve the police and local legal aid the same day; retaliation that crosses into intimidation is more than a housing matter.
The Evidence That Wins These Cases
Dated written repair requests, texts, and emails to the landlord. The building inspector’s or code enforcement agency’s complaint record, inspection report, and orders — these are the strongest 704.45(1)(a) proof because they are government records with dates. The landlord’s own notices with their dates on them (rent increase, nonrenewal, 5-day or 14-day notice), showing the sequence after your complaint.
Any statement by the landlord tying the two together — a text saying “you called the inspector, so you’re out” is close to a case-winner; save the original, not a retyped copy.
For lockouts: timestamped photos and video of the changed lock, removed door, or shut-off meter; the police incident number; a locksmith’s or utility company’s statement about who ordered the change or disconnection; utility account records showing who cut service and when. Receipts prove the pecuniary loss that Wis.
Stat. 100.20(5) doubles — hotel folios, restaurant receipts, storage invoices, replacement-property costs, mileage, lost-wage records from your employer. Neighbor or witness statements with names and phone numbers. Comparison evidence that other tenants who did not complain were not treated the same way. Your rent payment records showing you were current, which closes off the Wis. Stat. 704.45(2) nonpayment defense.
Worth knowing in Wisconsin: Wisconsin runs its tenant protections through the consumer-protection agency DATCP rather than the attorney general, so the ATCP 134 rules and the double-damages-plus-attorney-fees remedy in Wis. Stat. 100.20(5) are usually a stronger tool than Wis. Stat. 704.45 alone.
A series of state laws, including 2011 Wisconsin Act 143 and 2017 Wisconsin Act 317 (effective April 18, 2018), preempted much local landlord-tenant regulation, so Madison and Milwaukee tenants generally cannot rely on stronger city ordinances that existed before — check your local ordinance status before assuming extra protection.
Unlike many states, Wisconsin sets no day-count retaliation presumption and no per-day lockout penalty, so your dated documentation and your receipts do the work.
