Negligent security claims generally come up when harm is tied to a property’s failure to take reasonable steps to protect people from foreseeable criminal or dangerous acts.
In Lancaster, common fact patterns include:
- Assaults or robberies near parking lots and entrances where lighting was poor or access points were easy to bypass
- Incidents involving multi-family entrances, lobbies, or shared hallways where doors/locks weren’t functioning or entry procedures weren’t followed
- Threats, stalking behavior, or harassment that continued despite warning signs the property should have addressed
- After-hours incidents tied to staffing, patrol practices, or delayed response
- Visitor-related risks at properties with public access—where signage, monitoring, and supervision don’t match the level of public foot traffic
The point isn’t that a property guarantees safety. The legal issue is whether the owner or operator took reasonable precautions in light of what they knew (or should have known) about the risk.
