Inadequate security and assaults on property

Someone attacked you in a car park, a corridor, a lobby, or a hotel hallway. The person who did it is the one at fault, and is usually the one with no insurance and no assets. Whether anyone else answers for it depends on two things: foreseeability, and what a reasonable response would have cost. This is general information, not legal advice.

The starting point is unfavourable, and then it moves

There is no general duty to protect another person from the criminal conduct of a third party. A claim of this kind therefore depends on a special relationship between the defendant and the plaintiff — the kinds of relationship California recognises include landlord and tenant, business and customer, and hotel and guest — and on the harm having been foreseeable.

The duty, once it exists, is the ordinary one: reasonable care under all the circumstances, assessed on the multi-factor analysis California has used since Rowland v. Christian abolished the old visitor categories.

Sources: Rowland v. Christian (1968) 69 Cal.2d 108 (unified duty of reasonable care under all the circumstances); CACI No. 1000 (premises liability — essential factual elements), Judicial Council of California Civil Jury Instructions (2026 edition); Civ. Code, § 1714(a) (general duty of ordinary care).

Foreseeability, and why prior incidents dominate

This is the element the case lives or dies on, and prior similar incidents are the strongest evidence of it. What builds the picture:

• Prior crimes at the property. The closer in kind, location, and time, the stronger. A pattern of assaults in the same car park is worth far more than a general crime rate.
• Crimes in the immediate area, particularly where the owner knew of them.
• Police call history for the address, which is often obtainable and frequently reveals more than the owner's own records.
• Complaints from tenants, staff, or customers about lighting, broken locks, loitering, or trespassers.
• The owner's own prior recognition of the risk. The most useful category: an owner who once had guards, or working gates, or cameras, and then removed or stopped maintaining them, has already conceded that the risk was real.
• The nature and hours of the operation, and the physical layout — concealed approaches, unlit corners, isolated stairwells.

The burden side of the balance

Foreseeability alone does not settle what was required. California weighs the burden of the proposed measure against the degree of foreseeability, and the more onerous the measure, the more foreseeable the harm must have been before it is demanded.

In practice that sorts measures roughly into:

• Low burden, readily required. Working lighting, locks that lock, gates that close, trimmed landscaping, cameras that are actually recording, and repairing what is broken.
• Higher burden, requiring more. Staffed security patrols, controlled access systems, and monitored camera systems.

Which is why the strongest of these cases is rarely "they should have hired guards." It is "the gate had been broken for months, the lights in that corner had been out since spring, and three people had already complained."

Causation

The second real hurdle. It is not enough that security was inadequate — the inadequacy has to have been a substantial factor in the harm. A working lock on the door the assailant used, lighting in the place the attack happened, a functioning camera the assailant would have seen. The doctrine belongs to the claims process; what matters here is that the specific failure has to connect to the specific attack.

Evidence to secure early

• Surveillance footage — from the property and from neighbouring businesses. Days, not weeks.
• Police reports for the incident, and call history for the address.
• Prior incident reports and complaints held by the owner or manager.
• Maintenance records for lighting, locks, gates, and camera systems.
• Security contracts, patrol logs, and any decision to reduce or end a service.
• Photographs of the lighting and layout at the same time of day.
• Witnesses, including staff and residents who knew the history.

Common questions

Can a property owner be responsible for a crime someone else committed?

Sometimes. There is no general duty to protect against third-party criminal conduct, so the claim depends on a special relationship and on foreseeability. Where the risk was foreseeable and the owner failed to take reasonable measures, responsibility can attach.

What makes an assault foreseeable?

Most powerfully, prior similar incidents at or near the property. Also relevant: the nature of the business and its hours, the physical condition of the site, complaints from tenants or staff, and whether the owner had already recognised the risk by installing measures and then letting them fail.

Does the owner have to hire security guards?

Not necessarily. The more burdensome the measure, the higher the degree of foreseeability required before it will be demanded. Lighting, working locks, trimmed landscaping, and functioning cameras sit at the low-burden end and are required far more readily than staffing.

The assailant was caught and convicted. Does that end my civil claim?

No. The criminal case punishes the assailant and rarely produces a recovery. The civil claim against the property owner is separate, reaches insurance, and turns on the owner’s own failure rather than on the assailant’s guilt.
