California Negligent Security Law: Statute, Standards & Key Cases

A woman is raped in the underground parking garage of a Los Angeles apartment complex. The garage has one working light out of twelve. The electronic gate that controls vehicle access has been stuck open for two months. There are no security cameras. Management received written complaints from four tenants about the broken gate and the dark conditions. The response was the same each time: nothing.

The rapist faces criminal prosecution. The property owner faces a negligent security claim under California's broad premises liability framework — and California gives plaintiffs more tools to pursue these claims than most states.

California imposes a general duty of care on all property owners, follows pure comparative negligence (meaning you can recover even if partly at fault), and has decades of California Supreme Court decisions defining when criminal acts are foreseeable. This guide covers the current law.

Statute of Limitations

Two years from the date of the injury. Under California Code of Civil Procedure § 335.1, you have two years to file a negligent security lawsuit.

Claims against government entities have much shorter deadlines. You must file an administrative claim with the government agency within six months of the injury. If the claim is denied, you then have six months to file a lawsuit. Missing the administrative claim deadline can bar the lawsuit entirely.

Tolling exceptions: The statute may be tolled for minors (until they reach 18), for persons who are mentally incapacitated, or under the delayed discovery rule — if the plaintiff did not know and could not reasonably have discovered the basis for the claim. However, California courts have held that suspicion of wrongdoing triggers a duty to investigate, and the plaintiff cannot simply wait for facts to find them (Norgart v. Upjohn Co., 21 Cal.4th 383 (1999)).

Legal Standard

The General Duty of Care

California's approach to premises liability is broader than most states. Under California Civil Code § 1714, every person is responsible for injuries caused by their failure to exercise "ordinary care" in managing their property. This statute imposes a general duty of care on all property owners — there is no threshold requirement to prove a special relationship before the duty kicks in.

For negligent security claims, this means property owners must exercise ordinary care to protect people on their property from foreseeable criminal acts by third parties.

California Does Not Use a Status-Based System

Unlike Texas and some other states, California does not classify visitors as invitees, licensees, or trespassers to determine the duty of care. Since the landmark decision in Rowland v. Christian, 69 Cal.2d 108 (1968), California applies the same general duty of ordinary care to all persons on the property, regardless of their legal status. The question is simply whether the property owner acted reasonably under the circumstances.

Foreseeability

The central issue in California negligent security cases is whether the criminal act was foreseeable. California courts evaluate foreseeability using a totality of the circumstances test, not a rigid "prior similar incidents" requirement.

The California Supreme Court has developed a sliding scale for the relationship between foreseeability and the burden of the required security measures:

• High foreseeability (multiple prior similar incidents) may require heightened security measures such as hiring security guards.
• Lower foreseeability (general awareness of crime risk without specific prior incidents) may only require minimal security measures such as adequate lighting and functioning locks.

Factors courts consider:

• Prior criminal incidents on or near the property
• The nature and character of the surrounding neighborhood
• The type of business and its hours of operation
• The property's physical layout and design
• Whether the owner was aware of conditions creating a crime risk
• Industry security standards for the property type

Pure Comparative Negligence

California follows pure comparative negligence as established by Li v. Yellow Cab Co., 13 Cal.3d 804 (1975). Under this system, a plaintiff can recover damages even if they are mostly at fault. The recovery is simply reduced by the plaintiff's percentage of fault.

If a jury finds the plaintiff 70% at fault and the property owner 30% at fault, the plaintiff recovers 30% of their total damages. There is no threshold that bars recovery entirely.

This makes California significantly more favorable for plaintiffs than states with modified comparative fault systems (like Florida and Texas), where being more than 50-51% at fault bars all recovery.

Key California Cases

Isaacs v. Huntington Memorial Hospital (Cal. 1985)

The California Supreme Court held that a hospital could be liable for the shooting of a doctor in its parking lot, even without evidence of prior similar violent crimes on the property. The court established that foreseeability should be assessed under the totality of the circumstances — including the property's location in a high-crime area, inadequate lighting, and poor security — rather than requiring prior similar incidents as a prerequisite. This case rejected the narrow "prior similar incidents" test that some jurisdictions require.

Ann M. v. Pacific Plaza Shopping Center (Cal. 1993)

The California Supreme Court established the sliding scale between foreseeability and the duty to provide security. The court held that imposing a duty to provide security guards requires a high degree of foreseeability — typically shown through prior similar violent incidents on the property. Mere awareness of property crimes (like theft) was not enough to require the hiring of guards. But lesser security measures (lighting, locks, design changes) may be required with lower levels of foreseeability.

Delgado v. Trax Bar & Grill (Cal. 2005)

The California Supreme Court clarified that a business has a special duty to respond when it becomes aware of an imminent risk of harm to a patron. In this case, bar employees were told about a potential confrontation in the parking lot and failed to intervene. The court held that even absent prior similar incidents, a duty to take reasonable protective action arises when the business has actual knowledge of an imminent threat. This expanded the duty beyond the Ann M. framework for situations where the business has real-time notice of danger.

What Property Owners Must Do

California's duty of ordinary care requires property owners to take reasonable steps to protect people on their property from foreseeable crime. The specific measures depend on the level of foreseeable risk:

Baseline Requirements for All Properties

• Functioning lighting in parking areas, walkways, and common areas
• Working locks on entry doors, gates, and access points
• Maintenance of physical security infrastructure (no broken gates left unrepaired, no burned-out lights left unreplaced)
• Reasonable visibility and sightlines (trimmed landscaping, no design features creating hidden areas)

Elevated Requirements for Properties With Crime Histories

• Security cameras in areas where criminal activity has occurred
• Controlled access systems (electronic gates, key-card entry)
• Security patrol or guard presence for properties with repeated violent incidents
• Response protocols when staff become aware of an imminent threat (per Delgado)

Tenant-Specific Protections

California's strong tenant protection laws impose additional obligations on residential landlords, including:

• Deadbolt locks on all exterior doors (California Civil Code § 1941.3)
• Working window locks
• Functioning entry systems for multi-unit buildings
• Maintenance of common area security features

Available Damages

Successful California negligent security claims may recover:

• Medical expenses — past and future, including emergency care, surgery, rehabilitation, and ongoing treatment
• Lost wages and earning capacity — past and future income
• Pain and suffering — physical pain from the injury
• Emotional distress — PTSD, anxiety, depression, and other psychological harm
• Loss of consortium — a spouse's claim for loss of companionship
• Wrongful death damages — if the victim died, under California Code of Civil Procedure § 377.60 (see our California wrongful death guide)
• Punitive damages — available where the property owner acted with malice, oppression, or fraud. Requires clear and convincing evidence.

California does not impose statutory caps on compensatory damages in negligent security cases. Punitive damages have no statutory cap, though courts may reduce excessive awards under due process considerations.

Practical Next Steps

If you were a crime victim at a California property with inadequate security:

Act within two years (six months if the property is government-owned). The statute of limitations is strictly enforced.

Document the property conditions. Photograph lighting, cameras, gates, locks, and any visible security deficiencies. Take time-stamped photos as close to the time of the incident as possible.

Get the police report. This documents the crime, location, time, and the officer's observations about the property.

Preserve all medical records. Emergency treatment, follow-up care, psychological treatment — all are evidence of damages.

Do not sign anything from the property owner or their insurer. Quick settlement offers are almost always below the claim's actual value.

Consult a California premises liability attorney. Expert testimony on security standards is typically required. An attorney can issue preservation demands to prevent the property owner from destroying security footage, maintenance records, and incident logs.
