Dreaming of keeping backyard hens in Hawaii? You may—but rules vary widely by island and city. Many places only allow two birds. Some allow more if your land is zoned agricultural. Roosters often cause issues due to noise. This guide explains key rules in Honolulu (Oʻahu), Maui County, Hawaiʻi Island, Kauaʻi and more—all in clear, simple English.
Island-by-Island Differences
In Hawaii, no single statewide rule covers chickens. Instead, each county sets its own rules—like Honolulu on Oʻahu, Maui County, Hawaiʻi County (Big Island), and Kauaʻi County. Urban zones tend to be strict. Rural or agricultural-zoned land often allows more birds and sometimes roosters.
Oʻahu (City & County of Honolulu)
- You may keep up to **2 chickens (or peafowl)** per household in most residential zones.
- Roosters are generally **not allowed**, especially where their crowing can disturb neighbors.
- Animal nuisance laws ban continuous noise—like crowing—for more than 10 minutes straight or intermittently for 30 minutes in a day.
- If your chickens are judged a nuisance, you may be ordered to remove them or face fines.
- No special permit is typically required—but nuisance laws still apply.
Maui County
County code doesn’t specify an exact limit for backyard birds—it refers to zoning under Chapter 16.08A. In practice:
- Residential zones usually mirror Oʻahu’s strict limits (around two hens).
- Agricultural or rural-zoned lots over one acre may allow more—up to **20 birds**, depending on parcel size.
- Check your zoning district—and contact the Department of Public Works to confirm if chickens are permitted.
Hawaiʻi County (Big Island)
Rules differ depending on zoning:
- In residential zones, small flocks (like two hens) are typically allowed—but keep them clean and quiet.
- Agricultural or larger zoned properties are freer—you may keep more hens and possibly roosters.
- Coops should meet general spacing, sanitation, and nuisance prevention guidelines.
Kauaʻi County
There is no clear published limit—but recent state legislation effective July 1 2024 requires counties to control feral chicken populations. That means:
- Feral chicken control programs are expected, including education and humane contraception.
- Rules around domestic flocks may tighten to reduce wild chicken impact.
- Residential zones likely follow a two-chicken default—unless local code provides otherwise.
Where You Live Matters Most
Your zoning district determines what’s allowed:
- Residential lots (city/town): Usually allowed up to 2 hens; roosters banned; no permit.
- Agricultural or rural zoned land: May allow larger flocks and roosters; rules based on lot acreage.
- No permit in most areas, but nuisance enforcement can require removal or penalties.
Key Rules to Follow
- Keep quiet hens—avoid noise more than 10 minutes nonstop or 30 minutes total in a day.
- Limit number of birds—typically **2 per property** unless zoning says otherwise.
- Roosters are usually not permitted in urban zones.
- Store coops clean and pest-free; prevent odors and rodents.
- Avoid roaming chickens—they must stay on your property.
Why These Rules Exist
Hawaii’s islands are small and densely lived. Too many birds can make noise, spread waste, attract pests, or disturb neighbors. Feral chickens have become a state-wide nuisance. Laws aim to balance personal chicken keeping with public comfort and environmental safety.
Summary Table
| Location | Hens Allowed | Roosters? | Permit Required? | Notes |
|---|---|---|---|---|
| Honolulu (Oʻahu) | Up to 2 hens | No | No | Strict noise nuisance law |
| Maui County | ~2 hens in residential; ≤20+ in ag zones | No in residential; possible in ag | Check zoning | Zone‑based limits |
| Hawaiʻi County (Big Island) | ~2 hens residential; more agriculturally | Possible in rural zones | Check county rules | Vary by zoning |
| Kauaʻi County | Probably ~2 hens, may vary | No in urban | Check local | State feral control law active |
Voices from Hawaii
“Each household within the city and county of Honolulu is permitted to possess up to two chickens or peafowl.” — Revised Ordinance of Honolulu, §7‑2.5(d)
Residents on Oʻahu have pointed out:
“Oʻahu’s city codes allow for two hens per household, but roosters are banned in residential zones.”
Steps to Stay Legal
- Check your **zoning map** to see if your property is residential or agricultural.
- Contact your **county planning or animal control** department to verify chicken allowances.
- If your parcel is over 1 acre or zoned agricultural, ask about larger limits.
- Avoid keeping roosters unless your land is agriculturally zoned.
- Maintain coop cleanliness, secure feed, and ensure chickens do not wander off property.
- Watch for nuisance complaints—excessive noise or odor may invite enforcement.
Final Thoughts
Hawaii’s chicken laws vary greatly by island and zoning. In most residential areas, you can keep up to two hens and no roosters, with no permit—but you must avoid creating a noise or odor nuisance. On agricultural or larger lots you may keep more birds, possibly including roosters, but zoning must support it. Recent state action on feral chicken control may lead to stricter rules, especially on Kauaʻi. If you share your island and area (or zoning type), I can help verify the latest rules for your property.
