Someone slipped on your driveway. A guest fell down your porch steps. California law has a specific answer to whether that is your legal problem, and it depends on what you knew about the hazard and whether you acted reasonably.
This guide covers:
- How California defines property owner liability
- Which visitors are owed a duty of care, including trespassers
- What defenses apply when a hazard was obvious or the visitor was partly at fault
- When to consult an attorney
The Reasonable Care Standard: What California Actually Requires
California does not hold property owners responsible for every injury on their land. Under California Civil Code Section 1714, the standard is ordinary care: the owner knew or should have known about a dangerous condition and fixed it or warned about it within a reasonable time. An owner who had no way to discover a hazard is in a different legal position from one who saw a broken step months ago and did nothing.
Courts look at how long the condition existed, whether the owner had prior notice, and how serious the foreseeable injury was. A spilled drink that sits ten minutes with no signage is different from rain pooling at a front door nobody used all day. Context drives the analysis.

Who Can Sue You, Including People Who Weren’t Invited
California abolished the old common-law categories that shielded property owners from injured trespassers. Under the Rowland v. Christian decision, owners owe reasonable care to all people on the property, with narrow limits under Civil Code Section 846 for certain recreational land. Even a trespasser can bring a claim if the owner’s negligence caused the injury and the trespasser was not committing a felony.
According to the National Safety Council, falls caused over 7 million preventable injuries in the United States in 2021. Visitor classification still influences claim strength, with invited guests in a stronger position, but it is no longer a hard legal barrier.
When You May Have a Defense
Liability is not automatic. The most commonly used defense is the open and obvious doctrine: if a hazard was so plainly visible that any reasonable person would have avoided it, the owner’s duty to warn is reduced. A pothole in a well-lit lot surrounded by cones differs from a crack hidden under a wet mat at an entrance.
California’s pure comparative negligence rule also applies. If the injured person was partly at fault, their recovery is reduced proportionally. Someone texting while walking past a clearly marked wet floor sign shares responsibility for the outcome. If you or someone close to you was hurt on someone’s property, you can ask a Los Angeles premises liability lawyer at ER Lawyers whether the facts support a claim.
When the Situation Calls for Legal Advice
Insurance coverage does not resolve whether liability exists. Insurers run their own investigations and assign fault percentages before making any offer, and the opening number is rarely the final one. Assuming it is often means accepting responsibility that was never yours, or leaving a valid claim undervalued.
ER Lawyers handles premises liability cases across Los Angeles, advising both injured parties and property owners on how insurers assign fault and what the evidence actually supports.
Frequently Asked Questions
Who is liable if a trespasser gets hurt on my California property?
California allows trespassers to bring premises liability claims after statute overturned the rule that shielded owners entirely. Liability depends on whether the owner’s negligence caused the injury and whether the trespasser was committing a felony. Owners who create conditions that attract trespassers, such as an unfenced pool near a school, carry more exposure than owners who had no reason to expect an uninvited visitor.
Does California require proof of negligence to win a premises liability claim?
Yes. The injured person must prove the owner knew or should have known about the condition, failed to fix or warn about it in time, and that the failure caused the injury. A fall does not automatically create liability. Notice, the hazard’s nature, and what a reasonable owner would have done all factor in.
Can posting a warning sign protect a California property owner from liability?
Signs reduce liability when clearly posted and specific enough to inform a reasonable person of the actual risk. A sign does not eliminate liability if the hazard was serious enough that repair was the appropriate response. They work as a short-term measure while a fix is arranged, not as a permanent substitute.
