Hawaii Dog Bite Laws: Liability, Dangerous Dog Rules, and Insurance
What Hawaii law expects from you as a dog owner — who pays after a bite, how a dog gets designated dangerous, and whether the state requires liability insurance. Every citation links to the official statute.
This page is not legal advice. It summarizes Hawaii state law as of 2026-07-13. Laws change and cities add their own rules — personally check the official statutes linked below, and talk to a licensed Hawaii attorney before acting on anything that matters.
| Liability rule | Mixed (statute + common law) |
|---|---|
| Bite statute | HRS § 663-9 (Liability of animal owners) and § 663-9.1 (Exception of animal owners to civil liability) |
| Dangerous-dog statute | HRS §§ 711-1140 to 711-1148 (Chapter 711, Part III, Dangerous Dogs) |
| Insurance requirement | "$50,000 minimum (court can set higher)" — conditional |
| When insurance is required | Only after a criminal conviction for negligent failure to control a dangerous dog under HRS § 711-1144 — not a blanket requirement for owning a dog, or even for owning a dog already declared "dangerous" |
Who pays when a dog bites — the Hawaii rule
Hawaii's core statute, HRS § 663-9, reads like strict liability: an owner is liable for a bite even without proof of knowing the dog was dangerous. But the statute's case notes cite a 1986 appeals ruling that this does not create true strict liability for an ordinary bite; it just removes a victim's need to prove prior knowledge. A separate part of the statute imposes absolute liability, but only for animals already known to be dangerous, wild, or vicious, similar to a "one bite" rule. Practically, a first bite can still make you liable under negligence, but once a dog has shown dangerous tendencies, liability is harder to avoid.
Hawaii gives owners defenses under HRS § 663-9.1: unlawful trespass by the injured person, or provocation of the dog without the owner's negligence. Under HRS § 142-75, once your dog bites a person, you take on an ongoing duty to prevent a repeat, and anyone can sue to force a review of your confinement or seek the dog's removal.
How a dog gets designated dangerous
Hawaii's dangerous-dog rules sit in the criminal code, HRS §§ 711-1140 to 711-1148, added in 2024. A dog is dangerous if, without provocation, it causes a bite injury to a person or another animal (§ 711-1140); breed cannot factor into that call. An officer can declare a dog dangerous on probable cause, and the owner has 30 days to contest it.
Once declared, HRS § 711-1142 requires microchipping and registration, adult supervision indoors, a locked escape-proof kennel when unattended outside, a leash of 4 feet or less with adult supervision on the property, and a leash plus basket muzzle off the property. Owners must post a warning sign and spay or neuter the dog unless a vet objects. After 3 years of compliance and a behavior-modification program, an owner can apply to lift the designation (§ 711-1143).
Violating these rules is itself a crime and can lead to seizure of the dog. A violation causing a bite is a misdemeanor: $1,000 to $2,000 and up to 6 months in jail. A violation causing serious injury or death is a felony, 1 to 5 years in prison, with mandatory euthanasia of the dog (§ 711-1144).
Insurance requirements
Hawaii does not require liability insurance just for owning a dog, even one already declared dangerous. The requirement only appears after a conviction: under HRS § 711-1144(3), an owner convicted of negligently failing to control a dangerous dog must get liability insurance or post a bond of at least $50,000, an amount a court can raise to cover future costs.
Hawaii state law has no broader insurance mandate tied to dog ownership. Counties may add their own requirements.
Worth knowing
- Breed cannot factor into the state's dangerous-dog designation, but counties can pass breed-specific rules. Maui and Kaua'i reportedly restrict pit bull-type dogs locally, per secondary sources, not verified county code.
- Hawaii is rabies-free and requires nearly all incoming dogs to go through quarantine, either 120 days or a faster release track for pets meeting pre-arrival requirements, with fees from $98 to $244.
- No Hawaii statute labels a leash-law violation as negligence per se in a civil bite case, though it could still count as evidence of negligence.
- HRS § 142-74 makes owners liable when their dog injures livestock or property on someone else's land, and requires confinement or destruction of the dog after a first incident.
Other states
Rules change at the state line — a dog that is fine at home can put you under a different liability standard on vacation. See the full 50-state table.
