Strict Liability vs. the One-Bite Rule in California

By the FigureMyTax Editorial Team · How we calculate

California has been a firmly strict-liability state for dog bites for nearly a century — its statute specifically displaced the older one-bite rule back in 1931.

What strict liability actually requires

Under Cal. Civ. Code §3342, a dog owner is liable for a bite when the victim is in a public place or lawfully present on private property — regardless of whether the owner knew the dog had ever bitten anyone before. This is the defining feature of strict liability: you don't need to establish the owner's prior knowledge, the way you would under a one-bite / scienter rule.

Where one-bite-style proof still matters

Strict liability has real limits. If you were trespassing when bitten, §3342 doesn't apply at all — you'd need to fall back on an ordinary negligence theory, which in practice often requires showing the owner knew or should have known the dog posed some risk, much like the one-bite approach California itself used before 1931.

Bites only, not every dog-related injury

California's strict liability statute is narrowly focused on bites. A dog that knocks someone down, scratches them, or causes injury some other way without biting falls outside §3342 entirely, requiring an ordinary negligence claim to recover.

Nearly a century of victim-favorable law

Because this strict liability framework has been in place since 1931, with no history-of-aggression requirement, California is routinely cited as one of the more victim-favorable states for dog bite claims — a meaningful contrast to the roughly dozen states that still rely primarily on a knowledge-based one-bite standard for most dog bite cases.

This is general information, not legal advice. Which theory applies, and how strong your evidence is under it, depends on the specific facts. Confirm your situation with a licensed California attorney.
