When someone gets hurt on another person’s property, the first legal question isn’t how badly they were injured. It’s why they were there in the first place.

Arizona ties the duty a property owner owes to the status of the person who got hurt. The same broken step can produce a strong claim or none at all, depending on whether the injured person was a customer, a guest, or someone who had no permission to be there.

This guide walks through that visitor-class ladder, explains what “notice” of a hazard means for an owner, and covers the sharpest exception in Arizona law: the rules that govern pools and the children drawn to them. It closes on how comparative fault and the filing deadlines shape what a premises liability claim is worth.

The Duty Depends on Why the Visitor Was There

Arizona premises liability sorts a person on someone else’s land into one of three classes. The class sets the duty.

Visitor classWho it describesDuty the owner owes
InviteeA person on the property for a purpose tied to the owner's business, or a member of the public the land is held open to: a store customer, an apartment tenant, a paying guestThe highest duty. Reasonable care to keep the property safe, which includes inspecting for hidden hazards and warning about or repairing them
LicenseeA person present with permission but for their own purpose: most often a social guest in a homeA duty to warn of known dangers the guest is unlikely to discover. No duty to inspect for hazards the owner doesn't know about
TrespasserA person with no permission to be on the propertyUnder ARS 12-557, only a duty to refrain from causing intentional, wilful, or wanton injury

The gap between the top and bottom of that ladder is wide. An owner owes an invitee an active duty to look for danger, not just to react to it. A grocery store can’t wait for a customer to find the spill; the law expects the store to inspect its own aisles.

A licensee gets less. The owner has to warn a social guest about a known trap the guest wouldn’t spot, like a rotted deck board the host already knows is soft, but the owner doesn’t have to go hunting for hazards on the guest’s behalf.

A trespasser gets the least. ARS 12-557 limits an owner’s duty to a single line: refrain from intentional, wilful, or wanton injury. An owner who sets a deliberate trap can be liable, but ordinary carelessness toward a trespasser usually isn’t enough.

Status can shift

A person’s class isn’t fixed for all time. A customer invited into the front of a store becomes something closer to a trespasser if they push through a marked “employees only” door into a back room.

Where the injury happened, and whether the visitor had permission to be in that spot, can change the duty that applies.

What “Notice” of a Hazard Means

Naming the duty is only half the analysis. Even for an invitee owed the highest care, an owner isn’t automatically liable for every hazard on the property. In most cases the injured person has to show the owner had notice of the dangerous condition.

Notice comes in two forms, and the difference often decides the case.

Actual notice means the owner knew. An employee created the spill, a tenant reported the broken railing weeks ago, or a manager walked past the hazard and left it. The owner had direct knowledge and did nothing.

Constructive notice means the owner should have known. The hazard sat there long enough that a reasonable owner inspecting the property on a sensible schedule would have found it and fixed it. A puddle that formed thirty seconds before a fall is different from one that sat for two hours.

That is why a premises case so often turns on a narrow question of fact: how long was the hazard there. The answer decides whether the owner had a fair chance to catch it.

This same notice problem drives most retail falls, which is why a store slip and fall usually rises or falls on the timeline.

Pools, Children, and the Attractive Nuisance Rule

Arizona’s most important premises exception involves water. A pool is the classic attractive nuisance, a hazard that draws young children who can’t understand the danger, and the ordinary trespasser rule bends around it.

Arizona has adopted the attractive nuisance doctrine, drawn from Section 339 of the Restatement (Second) of Torts. It can hold a property owner liable when a child too young to appreciate the risk is drawn to an artificial condition like a pool.

The duty attaches when the owner failed to take reasonable steps to guard against that risk. The doctrine can apply even though the child had no permission to be on the property, and that is the point.

The trespasser floor in ARS 12-557 doesn’t shield an owner who left a pool open to a wandering toddler.

Arizona backs that duty with a specific safety statute. ARS 36-1681 requires a barrier at least five feet high around a residential pool or contained body of water eighteen inches or more deep and wider than eight feet that is intended for swimming.

The statute is detailed on purpose. The barrier can’t have openings a four-inch sphere can pass through, has to sit at least twenty inches from the water’s edge, and can’t offer exterior footholds a child could climb.

Gates have to be self-closing and self-latching, open outward from the pool, and latch at least fifty-four inches above the ground. When a house wall forms part of the enclosure, the statute demands added protection, such as a four-foot interior barrier, a motorized safety cover, or self-latching doors.

A violation of ARS 36-1681 is only a petty offense on its own. But its real weight is civil: a barrier violation can support a negligence claim when a child reaches an unsecured pool and is hurt.

The data behind the pool rule

Drowning is the leading cause of death for Arizona children ages one through four, and the state’s own child-fatality reviewers judged 100% of those deaths preventable.

Three out of four of those children died in a pool, hot tub, or spa. The barrier rule and the attractive nuisance doctrine exist because an open pool is a known, foreseeable danger to a small child.

Comparative Fault Trims a Claim, It Doesn’t Kill It

Property owners and their insurers often argue the injured person is partly to blame: they weren’t watching where they walked, they ignored a warning sign, they wore the wrong shoes. In many states that argument can end a case. In Arizona it can’t.

ARS 12-2505 makes Arizona a pure comparative negligence state. If a jury finds the injured person partly at fault, the claim isn’t barred. The full damages are reduced in proportion to that person’s share of fault that was a proximate cause of the injury.

The math is straightforward. A jury that values the harm at $100,000 and assigns the injured person ten percent of the fault returns $90,000. Even a person found mostly responsible still recovers the share tied to the owner’s fault.

The statute draws one hard line. It withholds comparative negligence from a claimant who intentionally, wilfully, or wantonly caused or contributed to their own injury. Short of that, a partial-fault argument reduces a premises claim rather than defeating it.

That rule matters because owners raise fault in nearly every premises case. Knowing that comparative fault trims a recovery without erasing it changes how an injured person should weigh a lowball offer built on the idea that they were “careless.”

The Deadlines That Govern a Premises Claim

Deadlines decide premises cases before the facts ever get argued, so they deserve their own attention. More than one clock can run at once.

A general premises liability claim carries a two-year statute of limitations under ARS 12-542, measured from the date of the injury. Miss it, and the claim is gone regardless of how strong it was.

A separate and much shorter deadline applies when the property belongs to the government. A city park, a public swimming pool, a school campus, or a transit facility is a public entity, and ARS 12-821.01 requires a notice of claim within 180 days after the cause of action accrues.

That notice has to state the facts behind the claim and a specific settlement amount. Missing the 180-day window bars recovery against the public entity even though the two-year statute hasn’t run.

The notice deadline works differently for a child. Under ARS 12-821.01, a minor may file the notice of claim within 180 days after the disability of minority ends, which for a child means the clock can run from the eighteenth birthday, not the date of injury.

A family whose child was hurt on public property years earlier shouldn’t assume the claim has already expired.

When to Consult Counsel

Three situations warrant a same-week conversation with an attorney who handles premises cases.

The first is any injury on commercial or rental property where evidence disappears fast. Surveillance footage gets overwritten, spills get mopped, and broken fixtures get repaired, often before an injured person thinks to document them. The proof of how long a hazard existed, the heart of the notice question, is the first thing to vanish.

The second is a pool or water injury involving a child. The attractive nuisance doctrine and the ARS 36-1681 barrier rule make these claims distinct from an ordinary fall, and the analysis of who owed what duty is fact-heavy from the start.

The third is an injury on government property, where the 180-day notice deadline can quietly foreclose a claim long before the two-year statute. On any property where a city, county, or school district owns the land, an Arizona premises liability lawyer can identify which public-entity clock applies before it runs out.

For a household still deciding what to do in the days right after an injury, the companion resource on what to do when you’re injured on someone else’s property walks through the immediate steps. Read it alongside this guide for both the legal framework and the practical next moves.

Whether any premises claim succeeds always depends on the specific facts, which is why an early conversation with counsel is worth having.

Frequently asked questions

What are the visitor classes in Arizona premises liability?
Arizona sorts a person on someone else's property into one of three classes, and the duty owed changes with the class. An invitee is on the property for a purpose connected to the owner's business or as a member of the public the land is held open to, such as a store customer, and is owed the highest duty: reasonable care to keep the property safe, which includes inspecting for hidden hazards and warning about or fixing them. A licensee is present with permission but for the licensee's own purpose, such as a social guest, and is owed a duty to warn of known dangers the guest is unlikely to discover, but not a duty to inspect for unknown ones. A trespasser has no permission to be there, and under ARS 12-557 the owner owes only a duty to refrain from causing intentional, wilful, or wanton injury.
Does a property owner in Arizona have to know about a hazard to be liable?
Usually, yes. Outside a few exceptions, the injured person has to show the owner had notice of the dangerous condition, meaning the owner either knew about it or should have known about it. Actual notice means the owner knew, for example because an employee created the spill or a report was filed. Constructive notice means the hazard was there long enough that a reasonable owner inspecting the property would have found and fixed it. That is why the question of how long a hazard existed often decides a premises case.
Can a homeowner be liable when a child drowns in a backyard pool in Arizona?
Possibly. Arizona has adopted the attractive nuisance doctrine, drawn from Section 339 of the Restatement (Second) of Torts, which can hold an owner liable when a young child who can't appreciate the danger is drawn to an artificial condition like a pool and the owner failed to take reasonable steps to protect against the risk. The doctrine can apply even though the child was technically a trespasser. Separately, ARS 36-1681 sets residential pool-barrier requirements, and a violation of that statute can support a negligence claim. Whether any specific claim succeeds depends on the facts.
What does Arizona's pool fence law require?
ARS 36-1681 requires a barrier at least five feet high around a residential pool or contained body of water eighteen inches or more deep and wider than eight feet that is intended for swimming. The barrier can't have openings a four-inch sphere can pass through, must sit at least twenty inches from the water's edge, and can't have exterior footholds. Gates must be self-closing and self-latching, open outward from the pool, and latch at least fifty-four inches above the ground. Some exceptions apply, including a residence where every occupant is at least six years old. A violation is a petty offense, but it can also support a civil negligence claim.
Does comparative fault bar a premises claim in Arizona?
No. Under ARS 12-2505, Arizona follows pure comparative negligence. If a jury finds the injured person partly at fault, the claim isn't barred; the full damages are reduced in proportion to that person's share of fault that was a proximate cause of the injury. Someone found ten percent at fault recovers ninety percent. The statute withholds comparative negligence only from a claimant who intentionally, wilfully, or wantonly caused or contributed to the injury.
How long do you have to file a premises liability claim in Arizona?
A general premises liability claim carries a two-year statute of limitations under ARS 12-542, measured from the date of the injury. A much shorter deadline applies when the property belongs to a public entity, such as a city park, a public pool, or a school district: ARS 12-821.01 requires a notice of claim served within 180 days after the cause of action accrues, and missing that window bars the claim even though the two-year clock hasn't run. Because the deadlines differ and can apply at once, families should confirm each one with an attorney early.
