Key Takeways: A negligent security lawsuit holds a property owner or business responsible for failing to take reasonable steps against a foreseeable crime on its property. In California you must prove the crime was foreseeable, the security was unreasonable, and better security likely would have prevented the attack. The deadline is usually two years.
The light over the parking structure stairwell had been out for weeks. Tenants complained. The gate that was supposed to lock never did.
Then one night someone was waiting at the bottom of those stairs. The attacker ran off and was never found, but the hospital bills did not go anywhere.
That is a tough case to win, and also a case worth fighting for. Here is how California courts actually decide them.
The Legal Duty Behind a Negligent Security Lawsuit
It starts with California Civil Code 1714, which makes everyone responsible for injuries caused by their failure to use ordinary care in managing their property. Property owners cannot ignore known dangers just because the person who does the harm is a stranger.
California’s civil jury instruction for these cases, CACI 1005 (from the Judicial Council of California Civil Jury Instructions), puts the rule plainly. A business open to the public, or a landlord, must use reasonable care to protect patrons, guests, or tenants from another person’s criminal conduct on its property if the owner can reasonably anticipate that conduct. The jury then decides whether the steps the owner took were adequate and reasonable under the circumstances.
One quirk worth knowing: whether a duty exists at all is decided by the judge, not the jury.
Where Negligent Security Cases Happen
Negligent security claims come out of places people trust to be reasonably safe:
- Apartment complexes and gated communities
- Bars, nightclubs, and their parking lots
- Hotels and motels
- Shopping centers, strip malls, and parking structures
- Gas stations and convenience stores
- Hospitals and office buildings
The common thread is control. The owner or business controls the lighting, locks, cameras, gates, and staffing. Those choices decide how easy the property is for a criminal to use.
What You Have to Prove
California courts use a sliding scale. The more expensive and burdensome the security measure you say was missing, the more foreseeable the crime has to be.
| What the owner failed to do | How foreseeable the crime must be | Leading case |
|---|---|---|
| Hire security guards | High foreseeability, usually shown by prior similar crimes at the property | Ann M. v. Pacific Plaza Shopping Center (1993) |
| Take simple steps once danger is obvious, like calling 911 or providing an escort | Ordinary foreseeability is enough | Delgado v. Trax Bar & Grill (2005) |
| Fix broken locks, lights, or gates the owner knew about | Depends on the burden and the warning signs; balanced case by case | Rowland v. Christian (1968) factors |
Foreseeability: Did the Owner See It Coming?
In Isaacs v. Huntington Memorial Hospital (1985), a doctor was shot in the parking lot of the Pasadena hospital. The California Supreme Court looked at the totality of the circumstances rather than asking only whether an identical crime had happened there before.
Eight years later, in Ann M. v. Pacific Plaza Shopping Center, the court revisited that approach. It held that a property owner has no duty to hire security guards unless the danger is highly foreseeable. The court added that this “rarely, if ever, can be proven in the absence of prior similar incidents.” So for claims built around missing guards, the history of crime at that property matters a lot.
Reasonable Steps: Small Failures Still Count
Delgado v. Trax Bar & Grill shows the other side of the scale. A bar patron was asked to leave and was beaten by a group in the parking lot.
The court held that when a business knows danger is imminent, it must take reasonable, relatively simple, and minimally burdensome steps, such as calling the police. No prior crimes were required to impose that smaller duty.
Causation: The Hardest Part
This is where owners fight hardest. In Saelzler v. Advanced Group 400 (2001), a delivery driver was assaulted at an apartment complex with a known crime problem, and she still lost.
The court said “a mere possibility of such causation is not enough.” You must show that better security more likely than not would have prevented your attack. Video, police reports, and testimony about how the attacker got in become everything here.
Renters: Your Landlord’s Lock Obligations
If you rent in Los Angeles or anywhere in California, Civil Code 1941.3 sets minimum security rules. Landlords must install and maintain an operable deadbolt on each main swinging entry door and working locks on windows designed to open, with some exceptions for louvered and casement windows and certain upper windows. Exterior doors to common areas in multifamily buildings need locks that comply with fire and safety codes.
The landlord’s liability under 1941.3 generally kicks in after you give notice and they fail to fix the problem within a reasonable time. Report broken locks in writing and keep a copy. That piece of paper can become the backbone of a claim. For a broader look at owner responsibility, read our guide on when property owners are liable for your injuries in California.
Who Pays When the Criminal Is the One at Fault
California splits the blame between a negligent property owner and the criminal.
Under Civil Code 1431.2, each defendant’s share of non-economic damages, such as pain and suffering, is limited to their percentage of fault. In Weidenfeller v. Star & Garter (1991), a man shot in a bar parking lot had a jury assign 75% of the fault to the shooter, 20% to the bar, and 5% to him.
The bar paid non-economic damages based on its 20% share. Economic damages, like medical bills and lost wages, remain joint and several, so a negligent owner can still be on the hook for the full amount of those.
The attacker usually has no money and no insurance. The property owner and its insurer usually do. That is why who pays for economic losses, and how the jury divides fault, can decide what an injured person actually recovers.
Deadlines and Evidence
California generally gives you two years from the date of injury to file under Code of Civil Procedure 335.1. If the attack happened on public property, such as a Metro station, a public housing complex, or a city parking structure, a government claim must be filed within six months under Government Code 911.2.
Evidence disappears faster than deadlines. Security systems can record over old footage automatically. Ask for the footage to be preserved right away, photograph broken lights or locks, and keep every complaint, email, and text you or other tenants sent about safety. Retail properties raise their own issues, covered in our post on common premises liability cases in retail stores.
Final Thoughts
Being attacked changes how a person moves through the world. The parking lot you used every day feels different. So does your own front door.
Some survivors feel guilty for not being “more careful,” as if a broken gate were their fault. It was not. Healing takes the time it takes, and asking why someone else ignored a danger they could see is a fair question to ask.

Frequently Asked Questions
Can I file a negligent security lawsuit if the attacker was never caught?
Yes. A negligent security lawsuit is against the property owner or business, not the attacker, so it does not require an arrest or conviction. You still need to prove the crime was foreseeable and that reasonable security more likely than not would have prevented it. A police report helps establish what happened.
Can I still recover if I was partly to blame for what happened?
Yes, in most cases. California uses pure comparative fault, so your own share of blame reduces your compensation instead of wiping it out. Under Civil Code 1714, the same rule applies to injuries a person brings partly on themselves. A jury decides each party’s percentage based on all the evidence about what happened.
Can a hotel guest bring a negligent security claim?
Yes. Hotels owe guests reasonable care against foreseeable crimes on the property, which can include working door locks, controlled access, and adequate lighting in hallways and parking areas. The claim follows the same rules as other negligent security cases: foreseeability, unreasonable security, and a causal link to the injury.
What damages can I recover in a negligent security case?
Damages in a negligent security case can include medical bills, future treatment, lost wages, lost earning capacity, and pain, suffering, and emotional distress. Medical bills and lost wages are proven with records and pay stubs, while non-economic damages depend on how severe the injuries are and how long their effects last.
Does it matter if I was trespassing or did not belong on the property?
It can. California applies a general duty of care under Civil Code 1714 to everyone, and courts weigh the Rowland v. Christian factors, but your reason for being there may affect foreseeability and comparative fault. Guests, customers, and tenants are in the strongest position to bring a negligent security claim.
