Hawaii Equine Laws: A Practical Guide
Hawaii offers a unique blend of rural charm, tropical climate, and island lifestyle that attracts equine lovers and homesteaders alike. If you’re raising horses—or thinking about keeping backyard chickens alongside them—understanding Hawaii’s equine laws is essential. While the Aloha State promotes agricultural living, it also enforces strict laws around liability, land use, and animal welfare.
This guide breaks down what you need to know to own and manage horses legally in Hawaii, especially if you also raise poultry on your property.
Why Equine Law Matters in Hawaii
Horse ownership in Hawaii isn’t just a lifestyle choice—it’s a legal commitment. The state’s laws are influenced by its unique island geography, agricultural zoning systems, and animal protection regulations. If you’re managing both equines and poultry, the overlap in laws can affect:
-
Liability protections for horse owners
-
Zoning regulations for mixed-species properties
-
Animal cruelty prevention
-
Health and safety requirements
-
Fencing, contracts, and facility rules
Smart property planning is key. Tools like chickencoopcalculator.com help you design a layout that supports both species while staying compliant with Hawaii’s local ordinances.
Hawaii’s Equine Activity Liability Laws
Does Hawaii protect horse owners from lawsuits if someone is injured?
Yes—Hawaii has adopted a version of the Equine Activity Liability Act (Haw. Rev. Stat. § 663B-1 to 663B-3), which protects horse owners, stable managers, and instructors from being held liable for inherent risks associated with equine activities.
Here’s what the law provides:
-
You are not liable if someone is injured while riding or handling a horse, unless gross negligence or willful misconduct is proven.
-
Inherent risks include things like falls, bites, and unpredictable behavior.
-
You must post clear signage on your property warning of these risks.
Important: Without proper signage, you could still be sued—even if the injury resulted from an expected risk. Always post and maintain the required language at riding areas and barns.
Zoning Laws for Horses and Chickens in Hawaii
Can you keep horses and chickens together legally in Hawaii?
Yes, but the rules vary depending on your county (Oʻahu, Maui, Kauaʻi, Hawaiʻi Island) and zoning designation. Hawaii’s land use is tightly regulated due to limited space and environmental protection priorities.
What to check in your county zoning code:
-
Property must be zoned agricultural or rural residential
-
Minimum acreage per horse is often required (commonly 1–2 acres)
-
There may be limits on poultry numbers and rooster ownership
-
Coops and stables must meet setback requirements from neighboring property lines and water sources
Some municipalities require permits for animal structures, so check local regulations before you build. Chickencoopcalculator.com is a helpful tool to determine if your property meets space and layout requirements.
Animal Cruelty and Welfare Laws in Hawaii
What are the legal responsibilities for animal care in Hawaii?
Under Haw. Rev. Stat. § 711-1109, animal cruelty is a criminal offense. The law applies to all animals, including horses and poultry.
It is illegal to:
-
Deny animals necessary food, water, or shelter
-
Abandon or confine them in unsanitary conditions
-
Fail to provide medical care when needed
-
Overwork or mistreat animals physically or emotionally
Violations can lead to fines, jail time, and permanent bans on animal ownership. Even backyard poultry operations must meet basic animal care standards. Planning ahead with chickencoopcalculator.com ensures you create a legal, humane environment for all your animals.
Health Regulations: Coggins Tests and Biosecurity
Do horses in Hawaii need a Coggins test?
Yes. A negative Coggins test for Equine Infectious Anemia (EIA) is required when:
-
Transporting horses between islands or into Hawaii from the mainland
-
Attending equine events or shows
-
Selling or transferring horses
While poultry disease regulation falls under the jurisdiction of the Hawaii Department of Agriculture, horse owners must maintain separate feed, clean enclosures, and monitor for signs of illness to reduce risk.
If you’re raising poultry and horses on the same land, use biosecure design strategies—something you can plan easily with this animal layout calculator.
Hawaii’s Fence Laws for Horse Owners
Are you required to fence your horses in Hawaii?
Yes. Hawaii law follows a “fence-in” rule, which means you are legally responsible for keeping your horses on your property at all times.
Fencing guidelines:
-
Minimum fencing height: 4.5 to 5 feet for horses
-
Avoid barbed wire or broken materials that could cause injury
-
Ensure fencing is sturdy and maintained, especially with Hawaii’s high humidity and vegetation growth
-
Chickens should be securely enclosed to prevent predation by mongooses, wild dogs, and other local predators
For an accurate estimate of fencing needs and cost, chickencoopcalculator.com offers simple tools for measuring and designing perimeters.
Equine Sales, Leasing, and Boarding in Hawaii
Do you need a contract to sell or lease a horse?
Not legally, but written agreements are essential in case of disputes. Whether you’re selling a horse, leasing it, or boarding one for someone else, contracts help clarify responsibilities and legal risks.
What to include in an equine contract:
-
Horse identification and health history
-
Sale price or lease terms
-
Care obligations (e.g., farrier, vet)
-
Emergency and liability clauses
Likewise, if you sell eggs, chicks, or poultry equipment, document any sales or recurring transactions. It protects you in case of buyer disputes or animal health concerns.
Public Trail Riding and Land Use in Hawaii
Can you ride horses on public land in Hawaii?
Yes—but only in designated areas. Hawaii’s natural beauty offers stunning trails, but land use is highly regulated due to environmental protection concerns.
Follow these trail riding tips:
-
Ride only on officially approved horse trails
-
Clean up manure near staging and parking areas
-
Respect native vegetation and wildlife
-
Get a permit if required—some areas limit equine access by season or capacity
The Na Ala Hele Trail System offers equestrian options across the islands, but check with your local Division of Forestry and Wildlife before heading out.
Homesteading in Hawaii: Managing Horses and Chickens Together
Many Hawaii homesteaders aim for sustainability by raising multiple species—but doing it legally and efficiently takes some planning.
Smart mixed-species tips:
-
Build separate shelters and feed areas
-
Compost manure and bedding regularly
-
Rotate outdoor access to reduce soil degradation
-
Keep coop airflow high and use predator-proof materials

When to Talk to a Lawyer or Agriculture Official
Do you need legal help for your horse or poultry operation?
You might—especially if you:
-
Run a boarding or lesson-based equine business
-
Face a zoning dispute or neighbor complaint
-
Are drafting a sales or lease agreement
-
Need permits for a larger poultry or livestock setup
An agricultural or equine attorney familiar with Hawaiian law can help you stay on the right side of compliance and avoid penalties.
