Yes, keeping backyard chickens is legal in Oregon, but compliance with state and local ordinances is mandatory. The Oregon Department of Agriculture (ODA) permits poultry ownership under health and zoning regulations, while cities and counties impose additional restrictions, particularly in urban areas. Recent 2026 amendments to the Oregon Revised Statutes (ORS 602) emphasize biosecurity measures to mitigate avian influenza risks.
Key Regulations for Keeping Backyard Chickens in Oregon
- Flock Size and Zoning: Municipalities like Portland and Eugene cap flock sizes at 6–12 hens, excluding roosters, due to urban density concerns. Rural areas often allow larger flocks but require minimum lot sizes (e.g., 1 acre per 12 birds in Jackson County).
- Permits and Inspections: Some jurisdictions, including Multnomah County, mandate annual permits ($10–$25) and unannounced inspections by local animal services to verify coop sanitation and disease prevention.
- Coop Standards: ODA mandates coops be predator-proof, at least 2 feet from property lines, and equipped with proper ventilation. Counties like Clackamas require coops to be elevated to prevent flooding and rodent infestations.
