Keeping chickens and other fowl in unincorporated Orange County is governed by the County Zoning Code's animal-keeping standards (section 7-9-105, Pets and animals). Poultry and birds are limited by lot area, roosters and peacocks are generally not allowed in residential zones, and birds must be kept set back from neighboring dwellings and property lines.
In unincorporated Orange County, raising chickens is treated as animal keeping under the County Zoning Code rather than the OC Animal Care ordinances. The County standard limits the number of poultry, birds, rabbits, and rodents to one animal per 1,800 square feet of lot area, meaning the size of your parcel determines how many hens you may keep. Roosters and peacocks are not permitted in residential zones, a rule aimed at controlling crowing noise. Birds and other livestock must also observe setbacks: no bird (or equine, bovine, sheep, swine, or goat) may be kept, stabled, tethered, corralled, or confined within 50 feet of any structure used for human habitation other than the owner's, or within 20 feet of any property line. Because these are zoning standards, the exact allowance can be modified by the underlying zone, and the County may apply different rules in agricultural or specific-plan areas. Owners should confirm their parcel's zoning with OC Planning before building a coop. Separately, any nuisance from odor, accumulated manure, or noise can trigger county code enforcement regardless of the bird count.
Exceeding the per-square-foot bird limit, keeping a prohibited rooster or peacock, or violating the setback distances is a zoning code violation enforced by Orange County code enforcement, which can issue notices, citations, and orders to remove animals or come into compliance. Nuisance conditions may be cited independently.
