At its core, a negligent security claim asks whether the person in charge of a property took reasonable security steps in light of the risk that criminal harm could occur. This doesn’t mean a property owner guarantees absolute safety. Instead, the law generally looks at whether the security measures were reasonable for the property’s setting and history, and whether the owner had notice of risks that required stronger prevention.
In South Dakota, the “setting” matters. A downtown building with ground-level entrances and high foot traffic can require different precautions than a remote property with limited access. Likewise, a business that hosts events, attracts late-night customers, or operates in an area with documented public safety concerns may be expected to plan for foreseeable threats.
These cases frequently involve assaults, robberies, harassment, and other violent acts that occur on the premises or in areas closely tied to the property’s operations, such as parking lots, building entrances, hallways, stairwells, and shared walkways. Even when the attacker is a third party, a civil claim may still be possible if the property’s lack of reasonable security contributed to the opportunity for harm.
Because negligent security disputes are often fought on details—what the owner knew, what security policies existed, what equipment worked, and what response was taken—your claim needs more than a general statement that “security was inadequate.” It needs a documented story supported by records, witness information, and the timing of events.
