Negligent security is a civil legal theory used when someone is injured due to criminal conduct or foreseeable risks on a property, and the property owner or business did not provide reasonable protection. The focus is usually not on whether the attacker was “supposed” to be there, but on whether the property should have anticipated that harm could occur under the circumstances and took adequate steps to reduce that risk.
In Arizona, negligent security issues often arise in places where people routinely come and go: multi-unit housing, shopping centers, hotels, and parking structures. They can also arise in settings that feel private but still involve public access, such as leasing offices, employee entrances, and shared walkways. When a property’s security measures are outdated, poorly maintained, or ignored after warning signs, injuries can follow.
These claims are often emotionally complicated. Many victims worry they will be blamed for what happened, or that the property owner will argue the incident was “random.” A careful legal review looks past the attacker’s actions and examines whether the property’s own decisions created, increased, or failed to reduce the opportunity for harm.
