Backyard chickens in Mission Viejo, California
Everything you need to know before you start a backyard flock in Mission Viejo – the rules, the climate and the neighbors with teeth.
Can you keep chickens in Mission Viejo?
Thinking about a backyard flock in Mission Viejo? Before you build a coop, know this: Mission Viejo's municipal nuisance code specifically excludes chickens from the definition of allowed "household pets," effectively prohibiting backyard chickens within city limits. Read on for exactly what the ordinance says, why it differs from surrounding Orange County rules, and what alternatives exist.
No. Under the Mission Viejo Municipal Code, keeping chickens (or any poultry) on residential property is not permitted as of right. Section 9.59.110(a) designates as a public nuisance any "animals, livestock, poultry or bees kept, bred or maintained for any purpose or in violation of any provision of the City Municipal Code" (§ 9.59.110(a)). While Section 9.59.115(l) carves out an exception for "household pets," the ordinance expressly defines household pets to exclude chickens: "Household pets shall not include horses, cows, goats, sheep, other equine, bovine, ovine or ruminant animals, pigs, predatory wild animals, chickens, ducks, geese, turkeys, game birds or other fowl, or animals which normally constitute agricultural uses" (§ 9.59.115(l)). Because chickens are specifically excluded from the household-pet exemption, keeping them falls back under the general "animals/poultry" nuisance provision of § 9.59.110(a), and the City's Code Enforcement and Animal Services staff have confirmed to residents that chickens are not allowed within city limits. This differs from unincorporated Orange County (surrounding Mission Viejo), where a Residential Backyard Chicken Permit program allows up to 4 hens on qualifying lots — but that county ordinance does not apply inside incorporated Mission Viejo city limits.

Keeping a flock happy in Mission Viejo
🌡️ Climate
USDA Hardiness Zone 10b (Mediterranean/coastal Southern California)
Mission Viejo sits in USDA Hardiness Zone 10b, with mild, wet winters and warm, dry summers typical of coastal Orange County. Even though the city currently prohibits backyard chickens, residents interested in poultry-keeping in nearby unincorporated Orange County or other permissive cities should note that the mild climate here is generally very forgiving for chickens — frost is rare and extreme heat during Santa Ana wind events is the bigger husbandry concern, requiring good ventilation and shade in coops.
🦝 Who's after your hens
Suburban Orange County communities like Mission Viejo border open space and canyon habitat, so coyotes, raccoons, opossums, and skunks are regularly reported in residential neighborhoods, and red-tailed hawks and other raptors are common overhead. Anyone keeping poultry nearby (e.g., in unincorporated county areas) should use fully enclosed, hardware-cloth runs and secure latches, since these predators are agile and persistent.
🐔 Breeds that do well here
Heat-tolerant, calm breeds such as Leghorns, Australorps, Easter Eggers, Plymouth Rocks, and Rhode Island Reds generally do well in Southern California's warm, dry climate (for informational purposes only, given local keeping restrictions).
Our package comes with two Rhode Island Reds – hardy in heat and cold, and friendly with kids.
Questions people ask about Mission Viejo
▸Can I legally keep chickens in Mission Viejo, CA?
No. The City's nuisance ordinance (§ 9.59.110(a)) lists poultry among prohibited nuisance animals, and § 9.59.115(l) expressly excludes chickens from the definition of permitted 'household pets.' The City's Animal Services staff have confirmed to residents in writing that chickens are not allowed.
▸Are there any exceptions that let residents keep a couple of hens?
The ordinance's household-pet exception (§ 9.59.115(l)) does not cover poultry — it explicitly lists 'chickens, ducks, geese, turkeys, game birds or other fowl' as excluded from household pets, so there is no small-flock carve-out for residential lots in the city.
▸Is it different in unincorporated Orange County near Mission Viejo?
Yes. Unincorporated Orange County adopted Ordinance 2021-34, which allows chickens on properties zoned for and developed with detached single-family residences, subject to the county's Residential Backyard Chicken Permit. That county program does not extend into incorporated cities like Mission Viejo.
▸Are roosters allowed anywhere in Mission Viejo?
No. Since all poultry, not just roosters, are excluded from the household-pet exception and fall under the general animal-nuisance provision, roosters are likewise not permitted in the city.
▸What happens if code enforcement finds chickens on my property?
Residents have reported being cited under § 9.59.115 (referenced informally as '9.59.115-1' by some residents) for nuisance violations after neighbor complaints, with the City's Code Enforcement and Animal Services divisions confirming the prohibition and requiring removal of the birds.
