Pomona Chickens & Livestock Rules (2026): What You Need to Know

Pomona's zoning code under Title 18 establishes the framework for residential animal keeping, reflecting the city's transition from its historic agricultural roots to a predominantly urban community of approximately 150,000 residents. Hens are permitted as an accessory use in single-family residential zones provided the lot meets the minimum 7,200-square-foot threshold. Lots under 10,000 square feet are limited to a maximum of 5 hens, while lots of 10,000 square feet or larger may keep up to 10 hens. Roosters are categorically prohibited in all residential zoning districts to protect neighbors from crowing disturbances, consistent with the approach taken by most LA County cities.

Chicken coops and enclosed runs must comply with specific setback requirements. Enclosures must be positioned at least 20 feet from any habitable structure on an adjacent parcel and no closer than 5 feet to any property line. Coops must be fully enclosed to prevent free-roaming and must be constructed of durable materials that can be regularly cleaned and sanitized. The Planning Division issues Animal Keeping Permits, which require a site plan showing the proposed enclosure location relative to property boundaries and neighboring homes. Permits are subject to revocation if sanitation or nuisance complaints are sustained after investigation.

Larger livestock such as goats, sheep, and horses are limited to agricultural (AG) and rural residential (RR) zoning districts, with a minimum lot size of one-half acre. Equine keeping requires specific provisions for manure management and fly control consistent with LA County Department of Public Health guidelines. The city's proximity to Cal Poly Pomona, which maintains its own agricultural operations on campus, does not extend animal-keeping privileges to nearby residential neighborhoods. Residents interested in keeping livestock should verify their zoning designation through the Planning Division before acquiring animals.
