In Illinois, negligent security claims generally turn on whether a landowner took reasonable steps to protect people from foreseeable criminal or harmful conduct.
In Algonquin, that “foreseeability” question often becomes complicated by the way people move through the area:
- Parking lots and drive lanes where vehicles and pedestrians mix
- After-hours access (late shifts, evening business hours, weekend activity)
- High-traffic entry points where doors, gates, or vestibules may be used by many people
- Lighting and sightlines that change with seasons and construction
A key question is what the owner knew or should have known based on prior incidents, complaints, or conditions. For example, if there were earlier calls for service, documented safety complaints, or repeated trespass/assault reports and nothing meaningful changed, that can support the argument that the risk was not a surprise.
