Breaking a Lease in Wisconsin: Mitigation, Safety Exits and Subleases

By Steve Levine · Updated November 3, 2026

Short answer: Breaking a lease in Wisconsin starts with one strong protection: under Wis. Stat. § 704.29(2), anything your landlord claims is reduced by the net rent obtainable through reasonable efforts to re-rent. Tenants facing an imminent threat of serious physical harm, or sexual assault, can also end the tenancy under § 704.16 and owe no rent after the end of the month following their notice, and an untenantable unit lets you move out under § 704.07(4).

Wisconsin backs the mitigation rule with an unusual penalty. A rental agreement that accelerates rent on default or waives the landlord’s duty to mitigate is void and unenforceable under Wis. Admin. Code ATCP 134.08(3), not just the offending clause.

Safety exits under § 704.16

Imminent threat of serious physical harm

Section 704.16(1) lets you terminate and move out if you or your child faces an imminent threat of serious physical harm from another person if you stay. You must give the landlord notice in a manner allowed by § 704.21 and a certified copy of one of these:

a domestic abuse injunction under § 813.12(4) protecting you;
a child abuse injunction under § 813.122 protecting your child;
a harassment injunction under § 813.125(4) based on stalking conduct against you or your child;
a condition of release under chapter 969 ordering the person not to contact you;
a criminal complaint alleging the person stalked you or your child; or
a criminal complaint filed after the person’s arrest for a domestic abuse offense against you.

Sexual assault

Section 704.16(1m) lets you terminate after a sexual assault against you or your child with notice and a certified copy of a harassment injunction based on sexual assault, or a criminal complaint alleging the assault. This version does not require you to show an ongoing imminent threat.

What you owe afterward

Under § 704.16(2) and (2m), you are not liable for rent after the end of the month following the month in which you give notice or move out, whichever is later. That liability is itself subject to the landlord’s duty to mitigate under § 704.29(2), so if the unit is re-rented sooner, you owe less. Every Wisconsin residential lease must also include a notice of domestic abuse protections under § 704.14.

Military orders

Chapter 704 has no separate military clause, so servicemembers rely on the federal Servicemembers Civil Relief Act, 50 U.S.C. § 3955. It covers a lease signed before you entered service, and a lease signed while in service if you then get permanent change-of-station orders or deployment orders of at least 90 days. Deliver written notice with a copy of the orders. A monthly lease ends 30 days after the next rent due date following delivery, and no early termination charge is allowed.

When the unit becomes untenantable

Under § 704.07(4), if the premises become untenantable because of fire, water or other casualty, a condition hazardous to health, or a substantial violation of the landlord’s maintenance duties materially affecting your health or safety, you may move out unless the landlord promptly repairs, rebuilds or eliminates the hazard. You may also move out if the repairs themselves would impose undue hardship on you. If you stay, rent abates to the extent you are deprived of the normal use of the unit. Section 704.07 applies to all residential tenancies and cannot be waived.

Document the condition with photos and a building inspector’s report where possible before relying on this section. Our repairs and habitability guide covers the notice steps.

Leaving early without a statutory exit

If you simply move out, your landlord can claim rent and damages, but § 704.29(2)(b) reduces the claim by the net rent obtainable through “reasonable efforts” to re-rent. The statute defines those efforts as the steps the landlord would have taken if you had left in due course, in line with local rental practice for similar properties. Without proof that more was obtainable, you are credited with rent actually received from a new tenant, minus reasonable expenses. The landlord can also recover reasonable listing and advertising costs.

Early termination clauses are common, so read yours closely. A clause that accelerates all remaining rent on default, or waives the mitigation duty, does not just fail; under ATCP 134.08(3) it makes the rental agreement void and unenforceable. A reasonable fixed buyout that preserves mitigation may be enforceable and can be the cheapest route.

Subleasing and assignment

Wisconsin’s transfer rule turns on your type of tenancy. Under § 704.09(1), a tenant at will or a periodic tenant with a period shorter than year-to-year may not assign or sublease without the landlord’s agreement or consent. Other tenants, including most fixed-term tenants, may transfer unless the lease expressly restricts it. Either way, § 704.09(2) says a transfer does not release you from the lease without an express release, so ask for one in writing.

Worked example from Milwaukee

Tyrone rents a Milwaukee flat for $1,250 a month on a lease ending July 31. He accepts a job in Minneapolis and moves out February 28, five months early, after giving written notice on January 25. The landlord lists the unit the way it normally would and signs a new tenant at $1,200 a month starting April 1, spending $150 on listings.

Rent claim without mitigation: March through July, 5 x $1,250 = $6,250.
Credit for rent received from the new tenant, April through July: 4 x $1,200 = $4,800.
Remaining claim: $1,450, plus $150 in listing costs, for $1,600.

Under § 704.28(4)(b), because the landlord re-rented before Tyrone’s lease ended, his deposit, less lawful deductions, is due within 21 days after April 1, the date the new tenancy began. Estimate your own case in the break-lease cost calculator.

Your security deposit

For an early move-out, § 704.28(4)(b) sets the 21-day clock from the date your rental agreement terminates or, if the landlord re-rents first, the date the new tenant’s tenancy begins. The landlord must deliver or mail the full deposit less amounts lawfully withheld, such as unpaid rent and damage. Details on itemization and penalties are in the Wisconsin security deposit guide.

How to give notice and document your move-out

Give notice in writing; for a § 704.16 exit, attach the certified copy and deliver it by a method in § 704.21.
On a periodic tenancy, § 704.19(3) generally requires at least 28 days’ written notice.
Photograph the unit, return keys, and give a forwarding address in writing.
Keep any listings or applicants you referred, in case reasonable efforts are disputed.

Frequently Asked Questions

Does a Wisconsin tenant need a certified copy of the restraining order?

Yes. Section 704.16 requires a certified copy of the injunction, release condition or criminal complaint, not a photocopy, along with notice served in a way § 704.21 allows. Request certified copies when you obtain the order or complaint.

My lease says I owe all remaining rent if I leave. Is that enforceable in Wisconsin?

No. ATCP 134.08(3) makes a rental agreement void and unenforceable if it accelerates rent on default or waives the landlord’s mitigation duty under § 704.29. Talk to legal aid or DATCP before paying such a demand.

Can I sublet my Wisconsin apartment to cover the rest of my lease?

On a fixed-term lease, yes, unless the lease expressly restricts transfer, under § 704.09(1). Month-to-month tenants need the landlord’s consent. You stay liable unless the landlord expressly releases you.

When does my deposit come back if my landlord re-rents quickly?

Within 21 days after the new tenant’s tenancy begins, if that is before your own lease would have ended, under § 704.28(4)(b).

Is there a Wisconsin rule if the tenant dies mid-lease?

Yes. Under § 704.165, the tenancy ends 60 days after the landlord learns of the death, or at the end of the lease if sooner, and the estate owes no rent after that, subject to mitigation.
