If It Happened on Their Property, It May Be Their Responsibility
Property injuries have a legal name. If you were hurt because a property owner failed to maintain safe conditions, Wisconsin law may give you the right to recover — whether it happened at a business, a neighbor's house, or a government facility. We can tell you in one conversation whether you have a claim.

What Premises Liability Actually Means — and Why It Matters for Your Case
Premises liability is the area of Wisconsin law that holds property owners accountable when someone is injured due to unsafe conditions on their property. It covers far more than slip and fall accidents. If you were hurt because of a structural defect, a pool hazard, inadequate lighting, a security failure, dangerous equipment, or an electrical hazard, premises liability law may apply to your situation.
The legal question is not whether the property owner meant for you to get hurt. It is whether they knew — or should have known — about a dangerous condition and failed to fix it. Foreseeable means preventable. Preventable means liability. Our job is to connect the dots between their negligence and your injury.
As a premises liability attorney serving northeast Wisconsin, Janssen Law LLC handles these cases across commercial properties, residential homes, and government-owned land throughout the region.

The Types of Property Injuries We Handle
Premises liability claims arise from a wide range of unsafe conditions. We represent clients injured in situations including:
- Pool and water feature accidents on residential and commercial properties
- Inadequate or negligent security that allowed an assault or robbery to occur
- Structural defects — broken stairs, collapsing decks, unstable railings
- Dangerous or poorly maintained equipment on a property
- Electrical hazards, exposed wiring, and code violations
- Fires caused by negligent maintenance or missing safety equipment
- Falling objects and overhead hazards in commercial or industrial settings
If you were hurt in a situation that isn't listed here, that doesn't mean you don't have a claim. If the injury happened on someone else's property and an unsafe condition played a role, it's worth a conversation.
Commercial vs. Residential Properties — What Changes and What Doesn't
The standard of care differs between commercial and residential property owners, but liability exists in both contexts. Commercial businesses — retail stores, restaurants, hotels, office buildings, and industrial facilities — typically carry general liability insurance specifically designed to cover premises injury claims. That insurance exists because these businesses know people are on their property and accept a responsibility to keep it safe.
Residential property owners are held to a somewhat different standard, but they are not exempt. A homeowner who knows about a dangerous condition and fails to address it before guests arrive can be held liable. Landlords face additional obligations to tenants and their visitors under Wisconsin landlord-tenant law.
The presence of insurance on a commercial property is significant — it means there is typically a mechanism in place to compensate injured visitors. Insurance adjusters, however, work to minimize what they pay out. Having a premises liability attorney on your side changes the dynamic of that negotiation.
How We Build a Premises Liability Case
Some clients come to us days or even weeks after an injury — sometimes without having sought immediate medical attention. That delay does not erase the property owner's liability, and it does not prevent us from building a strong case.
We investigate premises liability claims by gathering:
- Incident reports filed at the time of the injury
- Maintenance logs and inspection records from the property
- Photographs and surveillance footage of the hazard
- Witness statements from others who saw the condition or the incident
- Expert documentation from engineers, safety consultants, or medical professionals
- Code compliance records and prior complaint history for the property
Evidence we uncover speaks louder than delay. Our team reconstructs what happened, documents the property owner's failure to act, and builds the record that connects their negligence to your injury — independent of how quickly you were able to see a doctor.

Frequently Asked Questions About Premises Liability in Wisconsin
What is premises liability in Wisconsin?
Premises liability is the legal doctrine that holds property owners responsible for injuries caused by unsafe conditions on their property. Under Wisconsin law, property owners have a duty to maintain reasonably safe conditions for people who enter their property. When they fail to meet that duty and someone is injured as a result, the injured person may have a legal claim for damages.Does it matter that I wasn't a paying customer or official guest?
It depends on your status under Wisconsin law. Invitees — people present for a business purpose — receive the highest protection. Licensees, such as social guests, are owed a duty to warn of known hazards. Even trespassers have limited protections in certain circumstances, and children may be protected under the attractive nuisance doctrine. We can assess your situation in a free case review and tell you exactly where you stand.What if the property owner says it was just an accident?
An accident caused by negligence is still a legal claim. Wisconsin law does not require the property owner to have intended the injury — only that they knew or should have known about a dangerous condition and failed to address it. If the hazard was foreseeable and the owner did nothing, that is the basis for liability.Can I still file a claim if I didn't get medical attention right away?
Yes. A delay in seeking treatment does not eliminate the property owner's responsibility for creating or ignoring an unsafe condition. We build premises liability cases from documentation — incident reports, maintenance records, witness accounts, and expert analysis — not solely from the timing of your medical care.What kinds of damages can I recover in a premises liability case?
Recoverable damages in a Wisconsin premises liability claim typically include medical expenses, lost wages, future medical care costs, pain and suffering, and in serious cases, compensation for long-term disability or loss of enjoyment of life. If a premises liability injury resulted in a death, surviving family members may have a wrongful death claim as well.
