In Washington State, there’s no single rule for backyard chickens. Instead, cities and towns set their own limits—often based on zoning, lot size, and whether chickens become a nuisance. Many counties don’t regulate chickens directly; local rules apply. This guide explains common patterns and highlights sample rules from key cities and counties across Washington.
Common Themes Across Washington
- Most places allow a set number of hens—typically 3 to 8—depending on lot size.
- Roosters are almost always banned in residential zones due to noise concerns.
- Chickens usually must be enclosed in predator-resistant coops or pens.
- Setbacks often require coops be 5–50 feet from property lines or neighbor dwellings.
- Some cities allow unlimited chickens—others cap them strictly.
- Egg sales or commercial uses are usually prohibited for backyard flocks.
- Complaints may result in enforcement or fines.
County-Level Overviews
King County (outside Seattle and Bellevue)
In unincorporated King County, rules depend on property size. There are limits such as one hen per 1,000 sq ft, often up to about 5 hens for smaller parcels. Chickens must stay in coops, and roosters are not allowed. Always check with county planning for specific lot-based limits.
Clark County (including City of Vancouver)
Backyard chickens are permitted, but roosters are banned within Vancouver city limits and its urban growth area. Local code allows hens with coop and enclosure in rear yard, following setbacks.
Other Counties (Spokane, Thurston, Yakima, etc.)
Many counties allow chickens in rural residential areas—often a standard of 4–10 hens with coop setbacks. Roosters are usually prohibited. Specific rules vary, so contact local county planning departments for exact limits and setbacks.
City-Specific Regulations
Seattle
Standard lots allow up to eight domestic fowl (hens or ducks). If your lot exceeds 10,000 sq ft, you may add one additional bird per 1,000 sq ft. Roosters are not allowed. Coops must be at least 10 ft from any dwelling on adjacent property. Structure must be fenced, predator-proof, clean, and odor controlled.
Bellingham
Hens and roosters are allowed with no set number limit, but coops must be enclosed, nuisance-free, and at least 50 ft from neighboring residences.
Everett
Up to five hens allowed without permit. For six or more, a facility license is required from Animal Services. Roosters are prohibited. Chickens must be enclosed, coops must meet health standards, and kept clean.
Federal Way
Up to four poultry (hens or ducks) allowed on lots under 0.8 acres. Larger lots (≥0.8 acre) may keep up to 20. No roosters except on large agricultural zones. Coops must be at least 10 ft from side and rear lines, not in front yard, and smaller than 200 sq ft unless a building permit is obtained.
Bremerton
A single license allows up to five hens per single-family lot; roosters are not permitted. Permit is annual and enforced through local code.
Tacoma
Up to six adult chickens per parcel (plus up to six pigeons). Roosters prohibited. Coop must be at least 12 ft from nearest dwelling, located behind the front building wall, and less than 200 sq ft (otherwise building permit applies).
Vancouver (Clark County)
Up to three hens allowed; roosters are not permitted. Chickens must be confined within the property, and coop/run must be in back or side yard. A livestock plan may be needed in urban growth areas.
Kirkland (King County)
In low-density residential zones, up to three chickens are allowed on small lots; more hens may be allowed for larger lots (not exceeding 20 total). Roosters are banned. Coops and runs must respect setbacks—structures larger than 100 sq ft must be 40 ft from property lines.
Checklist Before Starting in Washington
- Determine if you’re within city limits or unincorporated county.
- Contact your local city or county planning/zoning department.
- Ask how many hens are permitted and whether roosters are banned.
- Find out if a permit or licensing is required, and cost.
- Learn coop and run setback rules (distance from lot lines or homes).
- Build coop that’s predator-proof, ventilated, clean, and odor-free.
- Ensure feed is stored securely and manure is managed properly.
- Keep chickens confined; no free-ranging unless local code allows.
- Avoid selling eggs—backyard flocks are usually for personal use.
- Know enforcement rules—complaints may lead to fines or permit revocation.
Why These Rules Matter
Local regulations balance your right to keep hens with public health and neighbor comfort. Well-maintained, enclosed coops reduce pests, odor and noise. Limits on hens and bans on roosters prevent disturbance. Setbacks keep neighbors safe and reduce runoff or view impacts. Permits and inspections ensure sanitary standards. By following these rules, you can keep hens responsibly and legally.
Conclusion
Washington doesn’t regulate backyard chickens at the state level—local cities and counties do. Places like Seattle, Tacoma, Everett, Vancouver, Bellingham, Bremerton, and Kirkland each offer different rules, but most allow hens (3–8 or more depending on lot size), ban roosters, and require enclosures with setbacks. Rural counties often permit hens with fewer rules. Before getting chicks, check your exact location’s rules, plan a suitable coop, and respect your neighbors—then you can enjoy fresh eggs legally and responsibly.
