Backyard Chicken Law in Hawaii: A Complete Guide to Keeping Hens Legally
This guide covers everything you need to know about backyard chicken regulations across Hawaii’s islands—plus how to plan your coop using smart tools like the Chicken Coop Calculator.
Is It Legal to Have Backyard Chickens in Hawaii?
Yes, it is legal to keep backyard chickens in most parts of Hawaii—but zoning rules, noise restrictions, and flock size limits apply. Hawaii doesn’t have a single statewide policy for backyard poultry. Instead, each county and city sets its own rules.
As a result, what’s allowed in Honolulu might be restricted in Hilo or Lahaina. That’s why checking your local municipal code is crucial before getting chickens.
General Rules for Keeping Chickens in Hawaii
- Flock size limits: Often capped at 2 to 10 hens in residential zones
- Roosters may be restricted: Most counties limit or ban them due to noise
- Permit requirements vary: Some islands require applications or fees
- Setbacks for coops: Required distance from homes, property lines, and neighbors
- Sanitation standards: Cleanliness is required to avoid health or pest issues
If you’re unsure how many chickens your space allows, the Chicken Coop Calculator helps you determine the right flock size based on coop area and run space.

Your chicken coop must meet local zoning codes and health standards. In Hawaii’s tropical climate, proper airflow and rain protection are also essential for healthy birds and odor control.

- Coop must be enclosed to prevent escape and protect from predators
- Elevated design recommended to avoid flooding and pests
- Minimum setbacks: Often 10-25 feet from property lines or homes

HOAs and Chickens in Hawaii
Even if your county or city allows chickens, your homeowners association (HOA) may not. HOAs often have bylaws that prohibit livestock or poultry in the neighborhood.
Always read your community’s covenants, conditions, and restrictions (CC&Rs) before setting up a coop. Getting written approval from the HOA can save you from future disputes or fines.
