Wisconsin Slip and Fall Laws: Proving Premises Liability

To win a slip and fall claim in Wisconsin, an injured person must prove that the property owner was negligent, had actual or constructive notice of the hazard, and that the hazard caused the injury. Wisconsin uses a modified comparative-negligence rule (51% bar) under Wis. Stat. section 895.045.

Proving a slip and fall claim in Wisconsin

Wisconsin law requires a slip and fall plaintiff to establish four elements. First, the property owner owed a duty of care to the person who was injured. Under Antoniewicz v. Reszczynski, 70 Wis. 2d 836 (1975), Wisconsin abolished the old invitee/licensee distinction, meaning landowners owe a general duty of ordinary reasonable care to most visitors. The Safe-Place Statute (Wis. Stat. section 101.11) imposes an additional duty on employers and owners of public buildings to keep their premises as safe as the nature of the place reasonably permits.

Second, a dangerous condition must have existed on the property. Third, the owner must have had notice of the condition, either actual notice (direct knowledge) or constructive notice (the condition existed long enough that the owner should have discovered it through reasonable inspection). The notice standard is central to most slip and fall disputes in Wisconsin.

Fourth, the hazard must have been a cause of the plaintiff's injury and resulting damages. A plaintiff who can satisfy all four elements may recover compensation, subject to the comparative-fault reduction described below.

The open-and-obvious doctrine in Wisconsin

Many states treat an open-and-obvious hazard as a complete bar to a slip and fall claim. Wisconsin takes a different approach. In Wagner v. Wisconsin Mun. Mut. Ins. Co., 230 Wis. 2d 633, 601 N.W.2d 856 (Ct. App. 1999), the Court of Appeals held that in an ordinary negligence case, an open and obvious danger is merely a factor for the jury to consider when apportioning negligence, and it will not operate to completely bar the plaintiff's recovery.

This outcome follows directly from Wisconsin's comparative-negligence statute (Wis. Stat. section 895.045) and the Supreme Court's reasoning in Rockweit v. Senecal, 197 Wis. 2d 409, 541 N.W.2d 742 (1995). Because Wisconsin distributes fault proportionally, the jury can assign part of the fault to the plaintiff for confronting an obvious risk and reduce the damages accordingly, rather than eliminating the claim entirely.

The open-and-obvious doctrine survives as a true no-duty bar only in a narrow public-policy exception involving limited landowner-invitee relationships. In the typical slip and fall posture involving a business, apartment, or public premises, the doctrine is comparative, not absolute. If you slipped on a hazard you arguably could see, you may still have a valid claim.

Ice, snow, and natural accumulation in Wisconsin

Wisconsin does NOT follow the "natural accumulation" no-duty rule used in states like Illinois and Ohio. Under Antoniewicz v. Reszczynski, 70 Wis. 2d 836 (1975), and reinforced by the Safe-Place Statute (Wis. Stat. section 101.11), a land possessor owes invitees the ordinary duty of reasonable care to keep their premises safe. That duty extends to naturally accumulated ice and snow on parking lots, entryways, walkways, driveways, and stairs.

This means that if a store, office building, apartment complex, or private homeowner fails to reasonably address an icy or snowy condition on their own property, they can be held liable for a resulting fall. Liability is especially clear where the owner created or worsened the condition, such as through faulty drainage that causes refreezing, or by piling plowed snow in a way that melts and refreezes across a walkway.

Two narrow carve-outs exist. An abutting private owner is generally not liable for natural snow or ice on a public sidewalk that the municipality controls. And under Wis. Stat. section 893.83, a city, village, town, or county is not liable for ice or snow on a highway or bridge unless the accumulation has persisted for at least three weeks. Outside those two exceptions, Wisconsin property owners face real exposure for winter-weather slip and falls.

How fault is shared: Wisconsin's negligence rule

Wisconsin applies the modified comparative-negligence rule with a 51% bar, codified at Wis. Stat. section 895.045(1). Under this system, a plaintiff's contributory negligence does not bar recovery if their share of fault was "not greater than" the negligence of the defendant. This phrasing means that a plaintiff who is exactly 50% at fault can still recover (equal to the defendant). But a plaintiff who is 51% or more at fault is barred entirely.

When recovery is allowed, damages are reduced in proportion to the plaintiff's percentage of fault. For example, if your damages are $100,000 and the jury assigns you 30% of the fault, you recover $70,000.

An important nuance applies in multi-defendant cases. Wisconsin measures the plaintiff's negligence separately against each individual defendant. A plaintiff may therefore be barred from recovering against one defendant (whose fault is less than the plaintiff's) while still recovering from another defendant (whose fault is greater). This separate-comparison approach can significantly affect strategy in cases involving multiple property owners, contractors, or municipalities.

Deadlines: statute of limitations and government claims

The standard personal-injury statute of limitations in Wisconsin is three years from the date of injury. Wis. Stat. section 893.54(1m)(a) requires that an action to recover damages for personal injury be commenced within that three-year period. Wisconsin's discovery rule applies, but the clock starts when the plaintiff has sufficient evidence that a wrong was committed by an identified person, not simply when the full extent of the injury is known.

If you were hurt on property owned or operated by a state or local government, a second and much shorter deadline applies. Under Wis. Stat. section 893.80(1d)(a), you must serve a written notice of injury on the responsible government entity (and the responsible officer or employee) within 120 days of the incident. A separate itemized claim for damages must also be presented and disallowed before you can file suit. For injuries caused by a state employee, a parallel 120-day notice requirement applies under Wis. Stat. section 893.82(3).

Missing the 120-day notice deadline typically bars a government-entity claim even if the three-year filing window has not yet closed. The notice requirement is strictly enforced. If you slipped on a sidewalk, in a government building, or in a public park, contact an attorney promptly. For more detail on Wisconsin's general injury filing window, see the Wisconsin statute-of-limitations page.

What a Wisconsin slip and fall claim is worth

A successful slip and fall claim in Wisconsin can recover two categories of damages. Economic damages cover medical expenses (past and future), lost wages, reduced earning capacity, and the cost of any ongoing care. These are calculated based on actual financial losses and are not capped.

Non-economic damages compensate for pain and suffering, emotional distress, and loss of enjoyment of life. Wisconsin does not impose a general cap on non-economic damages in ordinary slip and fall cases. However, if your claim is against a government entity, Wis. Stat. section 893.80(3) caps total governmental liability at $50,000 per occurrence, which can significantly limit recovery in public-property falls.

Because Wisconsin uses modified comparative negligence, any fault assigned to the plaintiff directly reduces the final award. A jury finding of even 25% plaintiff fault on a $200,000 case reduces the net recovery to $150,000.
