You went somewhere you had every right to be. A parking garage, an apartment complex, a bar, a gas station at night. And someone attacked you there, hurt you, took something from you, or worse.

Now you’re wondering if anyone besides the attacker can be held responsible. In Arizona, the answer is often yes. A negligent security claim lets you pursue the property owner when their failure to provide basic protection, like working lights, cameras, or locks, made the crime possible.

Luis P. Guerra, LLC has spent more than 25 years pushing back when property owners cut corners on safety, and someone else paid the price. If a crime you didn’t cause left you hurt, here’s what proving that case in Arizona takes.

Key Takeaways

  • Negligent security is a type of premises liability claim, and Arizona courts require the same four elements as any negligence case: duty, breach, causation, and damages.
  • Foreseeability decides most of these cases, and the leading Arizona case on the subject grew out of a shooting in a Phoenix-area condominium parking lot.
  • Arizona’s pure comparative negligence system means you can still recover even if you share some of the blame.
  • Incident reports, maintenance logs, and lighting records usually settle these cases long before a jury ever sees them.

What Counts as Negligent Security in Arizona

Negligent security means a property owner failed to take reasonable steps to protect visitors from a foreseeable crime, and that failure allowed the crime to happen. It falls under premises liability, the branch of law that holds landowners responsible for injuries on their property, but it works differently than a typical slip-and-fall case.

A wet floor is a physical hazard. A dark stairwell with a broken camera, in a complex that’s logged several break-ins in recent months, is a security hazard, and the harm comes from another person’s criminal act rather than the condition itself. Arizona law still allows a claim in that scenario, because the property owner’s decision to ignore a known risk is what opened the door for the attacker.

The Four Things You Have to Prove

Every negligent security claim in Arizona rests on the same four elements that any negligence case needs, and missing one of them sinks the whole thing.

Duty

Property owners owe a duty of care to invitees, meaning customers, tenants, and guests invited onto the property for business or social reasons. That duty includes taking reasonable security measures once the owner knows, or should know, that criminal activity is a real risk on the premises.

Breach

A breach happens when the owner had that knowledge and did nothing meaningful about it. Ignoring a security guard’s warning, letting exterior lights stay broken for months, or cutting a security contract for budget reasons are the kinds of decisions that turn a known risk into a breach.

Causation

You have to connect the missing security measure directly to what happened to you. If a functioning camera or a working gate likely would have stopped or deterred the attack, that link supports your claim. If the attack would have happened regardless of what the owner did, causation gets harder to prove.

Damages

Finally, you need actual losses: medical bills, lost income, therapy costs, pain and suffering. Without measurable harm, there’s no claim to bring, no matter how careless the property owner was.

Foreseeability Is Where Most Cases Are Won or Lost

Foreseeability is the piece that separates a winning claim from a dismissed one, and Arizona courts take it seriously enough that it usually decides the case before a jury hears the facts.

Martinez v. Woodmar IV Condominiums Homeowners Association, decided by the Arizona Supreme Court after a man was shot in a Phoenix-area condo parking lot where the homeowners association knew a gang loitered there and had been warned it needed more security patrols. The court ruled that once an owner knows about a pattern of danger and does nothing, a jury gets to decide whether that inaction caused the harm. That single ruling is why prior incident reports carry so much weight in Arizona negligent security cases today.

Insurance adjusters lean hard on the idea that crime is random and unpredictable. It generally isn’t. Phoenix police logged 785 aggravated assaults and 185 robberies citywide in a single month in 2026, and national victimization data from the Bureau of Justice Statistics’ National Crime Victimization Survey shows violent crime tends to cluster around specific property types rather than spread evenly across a city.

A pattern of prior incidents, whether it’s assaults in the same parking lot, a string of break-ins, or complaints management ignored, is what turns unpredictable into foreseeable in the eyes of an Arizona court.

The Evidence That Actually Moves These Cases

Property owners rarely admit fault outright, so these claims usually come down to documentation.

  • Police reports from the incident itself and from any prior crimes on the property
  • Maintenance and repair logs showing how long lights, locks, or cameras sat broken
  • Security company contracts or termination records, especially budget-driven cuts
  • Photos or video of the scene taken close to the time of the incident
  • Witness statements from tenants, employees, or neighbors about known problems

A Phoenix negligent security attorney typically requests these records early, before a property manager has a reason to lose them. Cases that don’t settle end up in front of the Maricopa County Superior Court, where none of this evidence gets easier to find once it’s gone missing.

Frequently Asked Questions

Can I still file a claim if the police never catch the person who attacked me?

Yes, you can. Your claim is against the property owner for failing to protect you, not against the attacker directly, so an unsolved case doesn’t block it. What matters is whether the owner knew about the risk and ignored it.

What if I was somewhere I probably shouldn’t have been, like past closing hours?

It might reduce what you recover, but it won’t always wipe out your claim. Arizona’s comparative negligence rule splits fault by percentage, so a jury could still find the property owner mostly responsible. If you were trespassing at the time of the incident, that might change whether the business owed you a duty at all. Talk to an attorney before you assume you have no case.

How much is a negligent security case worth in Arizona?

It depends on your injuries, your medical bills, and how clearly the evidence points to the owner’s negligence. Cases involving permanent injury or wrongful death settle far higher than ones with short-term harm. An attorney can give you a realistic range once they’ve seen your records.

What if the property is owned by an out-of-state company?

You can still sue in Arizona, since the incident happened here and Arizona courts have jurisdiction over property located in the state. Out-of-state owners often carry larger insurance policies, which can work in your favor. It just takes a bit more work to serve them properly.

Do I need a lawyer, or can I deal with the insurance company on my own?

You’re allowed to handle it yourself, but insurers know most people undervalue these claims. Property owners and their insurers have lawyers built into the process from day one. Having your own levels that out.
