California Civil Code 3342 — Plain English Explanation

Strict liability means dog owners are responsible even if their dog never showed aggression before.

California Civil Code § 3342 is the statute that makes California a strict liability state for dog bites. If you were bitten in California, this is the law that governs whether the owner is automatically responsible — and under what circumstances that responsibility can be reduced or avoided. Here's what it actually says, and what it means in practice.

The statute reads: "The owner of any dog is liable for the damages suffered by any person who is bitten by the dog while in a public place or lawfully in a private place, including the property of the owner of the dog, regardless of the former viciousness of the dog or the owner's knowledge of such viciousness."

Breaking that down, three things matter. First, "the owner" — the person who owned the dog at the time of the bite, not a boarder, walker, or temporary caretaker. Second, "in a public place or lawfully in a private place" — coverage extends to parks, sidewalks, and streets, and also to private property where you had a legal right to be: an invited guest, a mail carrier, a delivery driver, a contractor performing work. The trespassing exception is real: if you were unlawfully on the owner's property, § 3342 generally doesn't apply. Third, "regardless of the former viciousness of the dog or the owner's knowledge" — this is the no-free-bite rule. The owner can't defend by showing their dog had never bitten anyone before. The bite itself establishes liability.

The phrase "lawfully in a private place" has been interpreted broadly by California courts. A person on the property in performance of a duty imposed by law — including postal workers, utility workers, and emergency responders — is lawfully there. A person with express or implied invitation from the owner is lawfully there. A neighbor who wanders into an unfenced yard without any invitation, on the other hand, may have a harder argument.

Section 3342 covers bites specifically. If you were injured by a dog without being bitten — knocked down, chased into traffic, or frightened into a fall — your claim likely runs instead under California's common-law negligence rule, which does require showing the owner knew or should have known the dog was dangerous. That's a meaningfully higher bar. An attorney can tell you whether your situation qualifies under § 3342 or requires a negligence theory.

Comparative fault still applies. California follows a pure comparative negligence rule: if an insurer can show you provoked the dog or ignored a warning, your recovery is reduced by your percentage of fault. But unlike states with a contributory negligence bar, California never eliminates your recovery entirely on fault grounds — even if you were 60% responsible, you still recover 40% of your damages.

The filing deadline under § 3342 is two years from the date of the bite for most adult victims, under California Code of Civil Procedure § 335.1. For children, the deadline is tolled until age 18, giving them until their 20th birthday. Government-entity defendants require a separate pre-lawsuit tort claim to be filed within six months.

One practical point that often surprises people: § 3342 doesn't require you to prove the dog's breed, history, or prior incidents. It doesn't require you to prove negligence on the owner's part. It just requires that you were bitten, that you were in a place you had a right to be, and that the named defendant owned the dog. That simplicity is why California dog bite claims tend to move faster and settle for more than claims in one-bite rule states — fault isn't in dispute, so the fight is about damages.
