Premises liability: when a property owner is responsible for an injury

Premises liability is the part of negligence law that applies to people who own, lease, occupy or control property. If a dangerous condition on the property injures someone, the person in control can be responsible when they failed to use reasonable care about that danger. Being hurt on someone else’s property is not enough on its own. An owner is not an automatic insurer of every visitor’s safety.

The rules come from state law, so the details differ. This guide uses California’s official civil jury instructions as a worked example, because they spell out the elements a jury is actually asked to find.

Negligence applied to property

In California, the official premises liability instruction asks a jury to decide four things: that the defendant owned, leased, occupied or controlled the property; that the defendant was negligent in the use or maintenance of the property; that the plaintiff was harmed; and that the defendant’s negligence was a substantial factor in causing the harm (CACI No. 1000, 2026 edition). The commentary to that instruction quotes the California Supreme Court’s statement that the elements of negligence and premises liability are the same: duty, breach, causation and injury.

Notice the word “controlled.” The same California commentary quotes a court holding that a defendant need not own, possess and control the property; control alone is enough. A tenant running a shop, or a business managing a building, can be the right defendant even if someone else holds title.

The basic duty in California is stated in CACI No. 1001: a person who owns or controls property “is negligent if that person fails to use reasonable care to keep the property in a reasonably safe condition.” The instruction adds that the person must use reasonable care to discover unsafe conditions and to repair, replace, or warn about them. Jurors may weigh factors such as the likelihood of harm, how serious it could be, whether the defendant knew or should have known of the condition, and how hard it would have been to protect against the risk.

Invitees, licensees and trespassers

Many states still decide how much care an owner owes by sorting the injured person into a category. Cornell’s Wex encyclopedia, an educational secondary source, describes the three traditional groups:

• Invitees. People who enter with the owner’s express or implied invitation, such as store customers. Wex says owners owe invitees reasonable care to keep the premises reasonably safe and to warn of known dangerous conditions (Wex: invitee).
• Licensees. People who enter with permission but without a mutually beneficial commercial relationship. Social guests are the usual example. Wex notes the duty varies by jurisdiction: some states impose liability only for willful or wanton injury, while others require owners to share what they know about dangerous conditions (Wex: licensee).
• Trespassers. People with no permission to be there. Wex says an owner is usually not liable to an injured trespasser, with an exception for some artificial hazards that endanger child trespassers (Wex: trespass). That exception is often called the attractive nuisance doctrine, which Wex describes as narrowly applied (Wex: attractive nuisance).

States that use a general reasonable-care standard

Not every state uses those categories as the test. Wex explains that in Rowland v. Christian (1968), the California Supreme Court abandoned the trespasser, licensee and invitee classifications in favor of a general duty of reasonable care, and that many states have since adopted that standard (Wex: invitee).

The categories have not vanished entirely in California. The commentary to CACI No. 1001 quotes the California Supreme Court: duties are no longer imposed “solely on the basis of rigid classifications,” but the reason a person was on the land may still bear on liability. That is why CACI No. 1001 lets jurors consider the likelihood that someone would come onto the property the way the plaintiff did.

Some states also limit owners’ duties by statute in specific settings. In Texas, for example, an owner, lessee or occupant who gives someone permission to enter property for recreation does not, by giving that permission, owe that person a greater degree of care than is owed to a trespasser. That limit does not protect an owner who was grossly negligent or acted with malicious intent or in bad faith (Tex. Civ. Prac. & Rem. Code § 75.002). This is a Texas rule with its own definitions, not a general one.

Notice: what the owner knew or should have known

Most premises claims turn on notice. California’s instruction on unsafe conditions says a defendant was negligent if a condition created an unreasonable risk of harm, the defendant knew or should have known about it through reasonable care, and the defendant failed to repair it, protect against it, or adequately warn of it (CACI No. 1003).

“Knew” is actual notice: the owner or its staff was aware of the hazard. “Should have known” is constructive notice. In California, CACI No. 1011 asks whether the condition was of such a nature and existed long enough that the defendant had time to discover it and, using reasonable care, repair it, protect against it, or warn about it. In cases involving a store or similar business, the instruction can add that owners must make reasonable inspections, and that a failure to inspect within a reasonable time before the accident may show the condition existed long enough to be discovered.

The flip side matters too. The CACI commentary quotes the California Supreme Court’s statement that if a store owner inspects its premises in a reasonable manner, no breach will be found even if someone is injured.

Evidence in a slip-and-fall case

California’s court self-help guide lists slips and falls as a common type of personal injury case and suggests keeping evidence such as photos of the scene or injuries, medical bills or doctor reports, witness statements and police reports (California Courts: personal injury). In a premises case, the evidence that tends to matter most is evidence about the condition and how long it was there: what the floor, stair or walkway looked like, whether there were warning signs, and when anyone last checked the area. Some of that evidence is in the owner’s hands, such as inspection logs or video, and may not be kept long. Our guide to spoliation of evidence explains preservation in more detail.

Your own fault, and government property

An owner may argue that you were careless too, for example by not watching where you walked. How that affects the claim depends on the state’s fault rule, which can reduce an award or, in a few places, bar it. See our guide to comparative vs. contributory negligence.

Injuries on public property often follow separate rules. California’s jury instructions point premises cases against public entities to a different set of instructions on dangerous conditions of public property (CACI Nos. 1000 and 1100). California’s court self-help guide also says that before you can sue a government agency, you must first file a claim with the agency, within 6 months for an injury (California Courts: government claims). Those are California rules. Other states set their own procedures, and our guide to civil statutes of limitations covers deadlines more generally.

• Identify who controlled the property. The owner, a tenant or a manager may each be a possible defendant.
• Photograph the condition. Capture the hazard, any warning signs, and the surrounding area as soon as you can.
• Collect witness names. Anyone who saw the hazard before or after the incident can speak to how long it was there.
• Ask that records be kept. Inspection logs, incident reports and video can be overwritten or discarded.
• Check for a government owner. Public property can carry a separate claim process and shorter deadlines.
