The short answer
In California a property owner is not automatically liable when someone commits a crime on their property, and is not an insurer of visitor safety. Liability turns on duty, and California scales duty to how burdensome the precaution is. Low-burden measures — lighting, locks, landscaping, cameras — can be required on ordinary foreseeability. A duty to hire security guards is treated as heavily burdensome and requires heightened foreseeability, which in practice means prior similar violent incidents on the property (Ann M. v. Pacific Plaza Shopping Center (1993) 6 Cal.4th 666; Delgado v. Trax Bar & Grill (2005) 36 Cal.4th 224).
We sell security guards, so start with the part that cuts against us: there is no general California law requiring a business to hire them, and a great deal of security marketing on this subject is legally wrong. “You could be liable, so hire guards” is not how California premises liability works, and an owner who buys on that basis has been sold something on a false premise.
What is true is more specific, more useful, and worth understanding before an incident rather than after one.
Where the duty comes from
The starting point is Civil Code section 1714: everyone is responsible for injury caused to another by their want of ordinary care. Property owners owe visitors a duty of reasonable care to keep the premises reasonably safe. Courts then work through the Rowland v. Christian factors to decide whether that general duty extends to the specific precaution a plaintiff says was missing.
The complication with crime is that the immediate cause is a third party's deliberate act. California's answer is a sliding scale, and it is the single most important thing to understand on this subject: the more burdensome the precaution, the more foreseeability is required before a court will impose it.
| Precaution | Burden as courts treat it | Foreseeability generally required |
|---|---|---|
| Working lighting in parking areas and walkways | Low | Ordinary. If it is dark and broken and you knew, that is a hard fact to defend. |
| Functioning locks, gates and door hardware | Low | Ordinary — and a repeatedly reported broken gate is close to indefensible. |
| Trimmed landscaping, clear sightlines | Low | Ordinary. |
| Cameras that record and retain footage | Low to moderate | Ordinary in most commercial settings. |
| Hiring security guards | Heavy | Heightened — normally prior similar violent incidents on the property. |
| Hiring armed guards, or additional guards beyond existing coverage | Heavy | Heightened, and courts have been explicit that this rarely succeeds without prior similar incidents. |
Ann M.established that a high degree of foreseeability is required before a landlord's duty of care includes hiring security guards, and that this degree of foreseeability rarely, if ever, can be proven without prior similar incidents of violent crime on the premises. Delgado refined the analysis, drawing the line between minimally burdensome measures and heavily burdensome ones. In Delgado itself, a few prior altercations between patrons were held insufficient to establish the heightened foreseeability needed to require the defendant to provide any guard, or additional guards.
The uncomfortable corollary
What actually decides these cases
Reading how negligent security claims resolve in California, the same handful of facts keep determining the outcome.
- What happened on this property before, and how similar was it. Not crime in the neighbourhood generally — on the property, and similar in kind. A history of vehicle break-ins is not usually notice of a violent assault.
- What the owner knew and when. Police call history, tenant and employee complaints, prior incident reports, insurer correspondence. All of it is discoverable.
- What the owner did after knowing. This is where cases are won and lost. An owner who received complaints and has a dated record of what they changed is in a fundamentally different position from one whose file is empty.
- Whether the measures in place were actually working. A camera system that was not recording, lights that had been out for months, a gate propped open nightly. Broken measures are worse than absent ones because they establish that the owner recognised the risk and then failed at it.
- If guards were on site, how the security was performed. Having undertaken the function, the standard becomes whether it was done with reasonable care — which is why licensing, supervision, post orders and reporting matter as much as headcount.
The framework in short
- Baseline duty
- Civil Code §1714 — ordinary care to keep premises reasonably safe
- Duty analysis
- Rowland v. Christian factors, applied to the specific precaution
- Low-burden measures
- Lighting, locks, landscaping, cameras — ordinary foreseeability
- Hiring guards
- Heavily burdensome — heightened foreseeability required
- Usual proof of heightened foreseeability
- Prior similar violent incidents on the same property
- Key authorities
- Ann M. (1993) 6 Cal.4th 666; Delgado (2005) 36 Cal.4th 224
- Not the standard
- General neighbourhood crime statistics, on their own
- Owner is not
- An insurer of visitor safety
What to do about it, in order of cost
- Fix the cheap things and keep them fixed. Lighting, locks, gates, sightlines, camera retention. These are the measures California requires on ordinary foreseeability, they are inexpensive, and failing at them is the most common fact pattern in a claim that survives summary judgment.
- Start a written incident and complaint log today. Date, what was reported, who reported it, what you did, when. This is the single highest-value hour of work available on this subject, and it costs nothing.
- Get the police call history for your address.If a plaintiff's lawyer will pull it after an incident, you should read it before one. It tells you precisely what your foreseeability picture looks like.
- Reassess after any serious incident. That is the moment the legal analysis changes, and the moment a decision to add coverage is both cheapest to make and most defensible.
- If you do use officers, use licensed and supervised ones. Verify the PPO licence at the BSIS lookup, confirm guard cards, insist on written post orders and daily activity reports, and confirm supervisor visits are scheduled and documented. If you have undertaken the function, the standard is whether you did it with reasonable care.
Do not let anyone sell you guards on a liability scare
Deciding whether your site needs officers
Tell us what has actually happened on your property and we will tell you honestly whether officers are the right answer or whether lighting, access control and a camera upgrade would do more for less. The quote tool returns exact pricing in about 60 seconds if you want the number first.
If you are working through this for a specific property, our property manager pages cover site-type specifics, and the cost guide sets out what coverage actually runs so you can weigh it against the other measures.
This is general information, not legal advice. Premises liability outcomes turn heavily on the specific facts of a property and an incident, and the law develops. Nothing here is advice about your situation, and it is not a substitute for a California attorney reviewing your circumstances. If you have had a serious incident, or you have received a claim, speak to counsel before making decisions about documentation or security changes.
