Neighbor’s Dog on Your Property in Hawaii: What the Law Actually Says
July 1, 2026
A neighbor’s dog wandering onto your property in Hawaii is more than a minor annoyance — it can be a genuine legal matter with real consequences for the dog’s owner. Whether the dog is digging up your garden, threatening your chickens, or simply trespassing on a regular basis, Hawaii law gives you a clear framework for understanding your rights and your options.
Hawaii addresses dog trespass through a combination of state statutes and county-level ordinances, and the rules are not identical across every island. What applies in Honolulu may differ slightly from what applies on the Big Island, Maui, or Kauai. This guide walks you through each layer of the law so you know exactly where you stand.
Important Note: This article is for general informational purposes only and does not constitute legal advice. If you are dealing with a serious or ongoing situation involving a neighbor’s dog, consult a licensed Hawaii attorney for guidance specific to your circumstances.
Is It Illegal for a Neighbor’s Dog to Be on Your Property in Hawaii
Yes — under Hawaii law, a dog that enters your property without your consent is legally classified as a stray. Honolulu’s Revised Ordinances define a “stray” or “stray dog” as any dog on the premises of a person other than the owner of the dog, without the consent of an occupant of those premises. This definition makes the situation clear: if you did not invite the dog, it is trespassing under local law.
The classification as a stray is not just a technicality. It triggers enforcement authority, gives you grounds to contact animal control, and establishes the legal foundation for any liability claim you may later pursue. When an owner fails to confine or control their dog, and that failure leads to an injury, they may face civil liability and even criminal penalties in some situations.
It is also worth understanding that Hawaii’s counties — Honolulu, Maui, Kauai, and the County of Hawaii (the Big Island) — each maintain their own animal control ordinances on top of state law. Hawaii’s counties have their own ordinances concerning dog ownership and control, and violations of these local rules can serve as strong evidence of negligence or fault in a dog bite or property damage claim. So even if state law sets the baseline, your county’s rules may provide additional protections.
At-Large and Leash Laws That Apply in Hawaii
Hawaii does not have a single statewide leash law, but every county enforces rules that effectively prohibit dogs from roaming freely off their owner’s property. Hawaii law requires dog owners to keep their pets under control at all times, and dogs cannot roam freely in public spaces unless they are in designated off-leash areas.
In Honolulu, the leash requirement is specific and enforceable. The law requires anyone handling a dog on a public street, school grounds, or other public places to have the dog on a leash, and this also applies if you are on private property without the owner’s consent. The leash must not be longer than eight feet, with some exceptions for service dogs and police dogs.
On the Big Island, Hawaii County’s code sets a similar standard. No person shall bring or permit any dog in any County park, public school ground, or airport unless it is held under control by a suitable leash not more than six feet long, and dogs on leashes are not allowed in any County beach park. The Big Island code also specifically penalizes owners whose dogs stray. The owner of any dog that strays upon any public lands or the private lands of another shall be fined, with escalating penalties for repeat offenses.
The Hawaiian Humane Society on Oahu confirms the broader rule: by law, dogs must be leashed on all public property except for off-leash dog parks, dogs must be leashed on the beach or when swimming in the ocean, and dogs may only be off-leash on private property with the permission of the property owner.
Key Insight: Leash length limits vary by county — Honolulu sets a maximum of eight feet, while Hawaii County and most others cap it at six feet. Check your specific county’s code if you are outside of Oahu.
Penalties for leash violations in Honolulu are meaningful. It is a $50 fine for the first offense and up to a $1,000 fine or 30 days in jail for subsequent offenses. These are not trivial amounts, and they reinforce that Hawaii takes off-leash and at-large violations seriously.
What to Do When a Neighbor’s Dog Won’t Stay Off Your Property in Hawaii
If a neighbor’s dog keeps entering your property, your first practical step is a calm, direct conversation with the dog’s owner. Many trespass situations stem from a gap in a fence or a habit the owner may not know about. A polite conversation — framed around the legal definition of a stray — often resolves the problem without further action.
If the direct approach fails, you have several formal options. You can contact your county’s animal control agency or the relevant humane society, file a complaint with the Honolulu Police Department (on Oahu), or request mediation. The Honolulu Police Department may recommend that neighbors consider resolving animal nuisances through the Mediation Center of the Pacific, though both parties should be aware that the center charges each of them an administrative fee.
You can also take practical steps on your own property. If a dog is kept outside, it must be securely fenced or tethered in a way that prevents escape and protects others from being harmed — that obligation falls on the dog’s owner, but reinforcing your own fence line can reduce intrusions while you pursue the formal complaint process.
For ongoing issues, document every incident in writing before you escalate. Keep a log with dates, times, photos, and descriptions of any damage. This record will matter if you later pursue a civil claim or need to demonstrate a pattern of behavior to animal control. See the documentation section later in this article for specific guidance.

Who Is Liable for Damage Caused by a Neighbor’s Dog in Hawaii
Hawaii law establishes clear liability for dog owners when their animal trespasses and causes damage. The primary statute is Hawaii Revised Statutes § 142-74. Under HRS § 142-74, if any dog, while on private property without the consent of the owner of that property, injures or destroys any sheep, cattle, goat, hog, fowl, or other property belonging to any person other than the owner of the dog, the owner of the dog shall be liable in damages to the person injured for the value of the property so injured or destroyed.
This statute is notable because it does not require you to prove the owner knew the dog was dangerous. The trespass itself, combined with the damage, is enough to establish liability for property losses. A historical Hawaii court annotation further reinforces this: facts showing that a dog was a trespasser and seen carrying off something were justification for an attack on the dog (8 H. 115, 1890).
For personal injury — such as a bite that occurs while the dog is on your property — the governing statute is HRS § 663-9. The owner or harborer of an animal, if the animal proximately causes either personal or property damage to any person, shall be liable in damages to the person injured regardless of the animal owner’s or harborer’s lack of scienter of the vicious or dangerous propensities of the animal. In plain terms, the owner cannot escape liability simply by claiming they did not know the dog was dangerous.
However, courts have interpreted § 663-9 carefully. The Hawaii Court of Appeals held in Hubbell v. Iseke that § 663-9 does not establish strict liability for canine-inflicted injuries, but merely clarifies that a victim who bases a case on negligence does not have to prove scienter. The statute means that one can prove negligence without having to prove scienter — the owner’s conduct simply has to be shown to be unreasonable.
There are limited defenses available to the dog’s owner. The owner or holder generally will not be liable if you were trespassing, the dog bit you because it was teased, tormented, or otherwise abused without the negligence of the owner, or the dog was defending itself or another. Since you are on your own property, the trespass defense does not apply to you — it would only apply if you had entered the dog owner’s premises unlawfully.
Keep in mind that Hawaii has a two-year statute of limitations for personal injury claims, including dog bite cases, meaning you must file your lawsuit within two years of the date of the injury.
| Type of Damage | Governing Law | Proof Required |
|---|---|---|
| Property damage (livestock, fowl, other property) | HRS § 142-74 | Dog was on your property without consent; damage occurred |
| Personal injury (bite or attack) | HRS § 663-9 | Dog caused injury; owner’s conduct was unreasonable (no scienter required) |
| Absolute liability (wild/vicious animal) | HRS § 663-9(b) | Animal is known by species or nature to be dangerous, wild, or vicious |
Can You Legally Remove or Detain a Neighbor’s Dog in Hawaii
This is one of the most misunderstood areas of the law, and it is important to get it right. In general, you cannot simply take a neighbor’s dog to a shelter or keep it as your own — doing so could expose you to theft or conversion claims. You cannot take a neighbor’s pet to an animal shelter or anywhere else; if you are concerned about the dog’s safety or worried it will hurt someone, call animal control.
That said, Hawaii state law does provide a specific procedure for stray dogs. Every person who takes into their possession any stray dog shall immediately notify the animal control officer and release the dog to the animal control officer upon demand. This means if a dog enters your property and you are able to safely contain it temporarily, your legal obligation is to notify animal control right away — not to hold the dog indefinitely or transport it yourself.
Animal control officers and authorized humane societies have the formal authority to seize and impound dogs found at large. Every officer shall seize any unlicensed dog found running at large or found upon any public highway, street, alley, court, place, square, or grounds, or upon any unfenced lot, and confine it in a pound or suitable enclosure for a period of forty-eight hours, during which time it shall be subject to redemption by its owner.
The practical takeaway: if a dog is on your property without consent, you may safely and temporarily contain it to prevent further damage, but you must call animal control immediately. Do not transport the dog yourself, and do not attempt to return it to the neighbor’s yard by crossing their property line.
Can You Harm or Kill a Dog That Trespasses on Your Property in Hawaii
This is one of the most sensitive questions in this area of law, and the answer requires careful reading of both state statutes and county codes. Hawaii does not give property owners a blanket right to harm or kill a trespassing dog.
Hawaii County’s code contains an explicit prohibition: Section 4-4-28 of the Hawaii County Code addresses injuring or poisoning dogs, providing that unless otherwise provided by law, no person shall willfully or negligently injure or poison a dog. Violating this provision can result in criminal penalties.
At the same time, Hawaii law does recognize a limited historical justification for defending property. The annotation to HRS § 142-74 notes that facts showing a dog was a trespasser and seen carrying off something were considered justification for an attack on the dog (8 H. 115). This is an old case annotation, not a modern statute, and it should not be read as a general license to harm a dog simply because it crossed your property line.
Under HRS § 663-9.1, liability defenses exist when an animal causes damage as a result of being teased or tormented, or when the use of the animal to cause damage was justified under Hawaii Revised Statutes Chapter 703 — the state’s justification and self-defense chapter. In practice, courts will look at whether the threat was immediate, serious, and could not reasonably be avoided by other means.
Important Note: Harming or killing a dog that is merely wandering on your property — without posing an immediate, serious threat to a person or livestock — is likely to result in criminal charges or civil liability. Always contact animal control first. Only in a genuine emergency, where a dog is actively attacking a person or your animals and there is no other option, might a defense apply. Consult a Hawaii attorney before taking any such action.

When to Contact Animal Control in Hawaii
Animal control is your most important formal ally when a neighbor’s dog repeatedly enters your property. Each county in Hawaii has its own animal control structure. On Oahu, both the Honolulu Police Department and the Hawaiian Humane Society share enforcement responsibility. Enforcement of animal welfare laws is determined by jurisdiction and may involve the Hawaiian Humane Society, the Honolulu Police Department, or other agencies.
You should contact animal control when:
- A dog enters your property without consent on more than one occasion
- The dog has caused damage to your property, livestock, or pets
- The dog has behaved aggressively toward you, a family member, or a visitor
- You have already spoken to the owner and the problem continues
- You believe the dog may be abandoned or without an owner
When animal control responds to a complaint, the process typically follows a structured path. The assigned officer meets with the complainant and investigates the complaint, which includes attempting to locate the owner of the offending animal. The officer initiates a miscellaneous crime report for animal nuisance and presents the owner with a Notice of Animal Nuisance Complaint (HPD-517 form on Oahu).
For first-time offenses that do not involve a bite, warnings are the typical starting point. For situations other than dog bites, warnings are encouraged for first offenses to provide notice to owners that their animal is offending someone and to provide reasonable time to remedy the problem. If the behavior continues after a warning, citations and fines follow.
If the situation involves a dog that has bitten someone, the response is more immediate. Impoundment options include securing the dangerous dog within the dog owner’s property, having the owner take the dog to a licensed veterinary facility or commercial kennel for boarding, or having the Hawaiian Humane Society respond to take custody of the animal.

How to Document and Build a Case Against a Repeat Offender in Hawaii
If a neighbor’s dog keeps returning to your property despite complaints, a well-documented record is what separates a successful legal or enforcement outcome from a frustrating dead end. Start building your file from the very first incident.
Your documentation should include:
- An incident log — record the date, time, duration, and description of each trespass event. Note whether the dog caused damage, displayed aggression, or simply wandered through.
- Photographs and video — timestamped images of the dog on your property, any damage caused, and the entry point (broken fence, open gate, etc.) are powerful evidence.
- Damage records — if the dog has destroyed property, injured livestock, or damaged landscaping, document the replacement or repair costs with receipts.
- Written communications — keep copies of any texts, emails, or written notes you have exchanged with the neighbor about the issue.
- Animal control reports — every time you file a complaint, request the report number and ask for a copy of the written record. These official reports establish a timeline of repeat violations.
- Witness statements — if a neighbor or visitor has seen the dog on your property, ask them to write a brief, signed statement with the date and what they observed.
Under Hawaii law, the violation of an animal control law in Hawaii can result in liability on the part of the violator, whether or not they own the dog. States, counties, and cities often have laws requiring dogs to be on leash or prohibiting them from being at large or from trespassing, and the violation is considered to be evidence of negligence. A documented pattern of ordinance violations significantly strengthens any civil claim you bring.
If the dog has bitten you or another person on your property, Hawaii law provides a specific legal pathway. The owner of any dog that has bitten a human being has the duty to take reasonable steps to prevent recurrence. Any person may bring an action in district court to determine whether conditions of the dog’s treatment or confinement have been changed to remove the danger, and the court may make any order it deems appropriate, including removal of the animal from the area or its destruction by its owner.
When your documentation is thorough, you have three practical options for escalation:
- Continued animal control complaints — each new incident adds to an official record and can trigger escalating fines for the owner.
- Small claims court — for property damage covered under HRS § 142-74, Hawaii’s small claims court (District Court) handles claims up to $10,000 and does not require an attorney.
- Civil lawsuit — for larger damages or personal injury, a personal injury attorney can help you pursue a claim under HRS § 663-9. Remember the two-year statute of limitations.
Pro Tip: Save all animal control complaint numbers in one place. Hawaii county agencies track repeat complaints, and a history of filed reports makes it much harder for an owner to claim they were unaware of the problem.

Dealing with a neighbor’s dog that repeatedly enters your property is frustrating, but Hawaii law gives you a clear set of tools. Start with documentation, move to direct communication, escalate to animal control when needed, and pursue civil remedies if damage has occurred. Knowing which statutes and ordinances apply — and keeping a thorough paper trail — puts you in the strongest possible position to protect your property and your rights.
