Negligent security falls under the broader category of premises liability law in California. Property owners and operators owe visitors a duty of care to ensure that their premises are reasonably safe from foreseeable harm. This includes not only protecting visitors from hazardous conditions such as slip and fall risks but also from foreseeable criminal activities. If a visitor is harmed due to a lack of adequate security measures, they may have a claim for negligent security.
Duty of Care and Foreseeability
For a negligent security claim to be valid, the plaintiff must show that the property owner owed them a duty of care. This duty exists in most cases where an individual is legally on the property, such as customers, tenants, or guests. In contrast, trespassers typically aren’t owed the same level of care.
An essential aspect of this duty is foreseeability. The property owner or operator must be aware, or reasonably should have been aware, of the potential security risks on their property. For instance, if a particular neighborhood has seen a recent uptick in criminal activity and a property owner fails to implement additional security measures, they may be found negligent if a visitor becomes a victim of a crime on their premises.
Types of Establishments at Risk
While any property can be subject to a negligent security claim, some establishments are more prone to such issues due to the nature of their operations or their location. Examples include:
- Hotels and motels
- Shopping malls and retail stores
- Parking lots and garages
- Apartment buildings and condominiums
- Bars and nightclubs
Proving Negligent Security
For a plaintiff to successfully claim negligent security, they must demonstrate:
1. Existence of Duty: The property owner or operator owed a duty of care to the plaintiff.
2. Breach of Duty: The property owner or operator breached that duty by failing to provide reasonable security measures.
3. Causation: The breach of duty was a substantial factor in causing the plaintiff’s harm.
4. Damages: The plaintiff suffered actual harm, which may include physical injuries, emotional distress, or financial loss.
Typical Security Measures
Reasonable security measures can vary based on the type of property and its location. Common measures include:
- Surveillance cameras
- Security personnel or patrols
- Adequate lighting in parking lots and common areas
- Locks, gates, and access control systems
- Alarm systems


Defenses Against Negligent Security Claims
Property owners might defend against a negligent security claim by asserting:
- Lack of Foreseeability: The criminal act was unforeseeable and, therefore, they had no duty to prevent it.
- Comparative Negligence: The plaintiff’s actions contributed to their harm.
- Lack of Causation: The inadequate security wasn’t a significant factor in the plaintiff’s injury.
Taking Legal Action
Negligent security claims in California premises liability law highlight the responsibility property owners and operators have in ensuring the safety of their visitors. Given the broad range of factors to consider — from the type of property to the nature of the security risk — such claims can be complex. Still, they underscore the importance of being proactive in preventing foreseeable harm. For those considering a claim, or property owners seeking to understand their obligations, consulting with legal experts knowledgeable in this area of law is crucial.
