This page is for California residents thinking about keeping a few backyard hens. California has no statewide right to keep backyard chickens, and no state law sets hen limits, rooster bans or coop setbacks for homes. Those rules come from your city or county, usually in the zoning code, the animal-control ordinance or both. The state's right-to-farm law (Civil Code §3482.5) protects commercial farms, not backyard flocks, so local rules and neighbor nuisance complaints still apply. The California Department of Food and Agriculture asks all poultry owners to practice biosecurity against bird flu and to report sick birds.
City rules vary widely across the 9 cities we cover for this topic. Lafayette and Los Altos allow hens without a permit: Lafayette scales the flock to lot size (4 birds on a 6,000 to 10,000 sq ft lot, up to 16 on lots over 40,000 sq ft), and Los Altos allows one small animal per 1,000 sq ft of lot. Hillsborough, Pasadena and Tiburon require a permit, registration or letter of permission first. Roosters are banned in Hillsborough, Lafayette, Manhattan Beach and Pasadena. Coop distances can be large: 35 feet from a neighbor's home in Pasadena and 125 feet in Hillsborough. Manhattan Beach counts hens toward its five-pet limit, Del Mar allows them only on large lots that meet distance rules, and Piedmont has no chicken-specific rules beyond its noise and odor limits. Pick your city below for the details and the municipal code text.
Town-by-town comparison
| Town | Verdict | Short answer |
|---|---|---|
| Los Altos | Allowed | Yes. In Los Altos single-family (R1) districts you may keep one small animal, such as a chicken, duck or rabbit, per 1,000 sq ft of lot area, so a 10,000 sq ft lot allows 10 in total. Coops can't be in the front setback and must be at least 10 ft from side and rear property lines. |
| Saratoga | Allowed | Probably yes, as pets, but this is our reading rather than an explicit rule: Saratoga's code doesn't mention chickens or hens by name, but R-1 zones allow keeping a "reasonable number" of birds for private use, as pets only and not for sale or breeding. There's no set hen limit or permit; the City judges what is reasonable based on lot size, noise, odor and closeness to neighbors. Confirm with Community Development before getting hens. |
| Tiburon | Allowed with a permit | Yes, with a chicken keeping permit from the Community Development Director. The permit is ministerial (no hearing), but your flock must meet the town council's adopted chicken keeping standards, which set the detailed rules such as numbers and coop placement and are not in the code text we reviewed. |
| Piedmont | Not specifically regulated | Piedmont's city code chapters we reviewed don't specifically regulate backyard chickens: there's no ban, hen limit, rooster rule or permit. Any animal kept in a way that causes excessive noise or offensive odors is prohibited, so a flock (and especially a crowing rooster) can be treated as a nuisance. |
| Lafayette | Allowed | Yes. Lafayette allows backyard chickens in all single-family zones without a permit: up to 4 on a 6,000-10,000 sq ft lot, 6 on lots up to 20,000 sq ft, 8 up to 40,000 sq ft, and 16 on larger lots. Roosters are banned, and the coop must sit in the side or rear yard, no taller than 8 feet, meeting the house's setbacks. |
| Manhattan Beach | Restricted | Hens appear to be allowed as small domestic pets in Manhattan Beach's residential districts, but they count toward a limit of five small household pets per home. Roosters, ducks, geese and other farm animals or livestock are not allowed. |
| Pasadena | Allowed with a permit | Yes, hens are allowed if you register with the city poundmaster. Keep chickens at least 35 feet from any neighbor's home and out of zoning setbacks, give each bird at least 10 sq ft of permeable enclosure, and keep no more than 10 fowl and rabbits in total. Roosters are banned citywide. |
| Del Mar | Restricted | Possibly, but only on a large lot. Del Mar's R1-10 zone allows 'other domestic animals' as long as any animal or coop is at least 75 feet from any window or door of a home and 40 feet from every adjacent property line. The code doesn't name chickens or set a hen limit, and outside such zone allowances only household pets are permitted. |
| Hillsborough | Allowed with a permit | Yes, but only with a letter of permission from Hillsborough's city manager. Roosters three months or older are banned, and the coop or pen must be at least 125 feet from any neighbor's house. |
California state rules on backyard chickens
California has no statewide right to keep backyard chickens, and no state law sets hen limits, rooster bans or coop setbacks for homes. Those rules come from your city or county, usually in the zoning code, the animal-control ordinance or both. Some cities allow a few hens by right, some require a permit, some ban poultry in residential zones, and many ban roosters.
A few state laws still matter:
- Right-to-farm protection is for commercial farms: Civil Code §3482.5 shields commercial agricultural operations that have run for more than three years from new nuisance claims. It doesn't protect a backyard flock from local rules or neighbor complaints.
- Cockfighting is a crime: under Penal Code §597b, making roosters fight for amusement or gain, or allowing it on your property, is a criminal offense. That's one reason some cities limit roosters.
- Bird flu (H5N1): the California Department of Food and Agriculture (CDFA) asks all poultry and livestock owners to practice biosecurity (limit contact with wild birds, monitor flock health) and to report sick birds. The CDFA bird flu line is 1-866-922-2473.
- Hen housing standards (Prop 2 / Prop 12, Health & Safety Code §25990 et seq.) set minimum space for egg-laying hens. They're aimed at commercial egg production and sales, not typical backyard flocks.
- Nuisance and health rules still apply: cities and counties can address odor, noise, flies and rodents under local nuisance and health ordinances.
Check your city's municipal code, and any HOA rules, before getting birds.
Common questions about chicken laws in California
- Is it legal to own a chicken in California?
- It depends on your city. No state law grants a right to keep backyard chickens or bans them; cities and counties decide through zoning and animal-control rules. Some allow a few hens by right, some require a permit and some ban poultry in residential zones, so check your city's municipal code and any HOA rules first.
- What are the backyard chicken laws in California?
- There's no statewide backyard chicken law setting hen numbers, coop setbacks or permits; those rules are local. State law does make cockfighting a crime (Penal Code §597b), and the right-to-farm law protects only commercial farms. In the cities we cover, limits range from a lot-size formula in Los Altos and Lafayette to a five-pet cap in Manhattan Beach.
- Can I keep a rooster in California?
- It depends on your city, but many ban them. State law doesn't ban roosters, but Hillsborough, Lafayette, Manhattan Beach and Pasadena prohibit them, and in other cities a crowing rooster can be treated as a noise nuisance.
- Do I need a permit to keep chickens in California?
- It depends on your city. There's no state permit for a small backyard flock. Among the cities we cover, Lafayette and Los Altos need no permit, while Pasadena requires registration with the poundmaster, Tiburon a chicken keeping permit and Hillsborough a letter of permission from the city manager.
- What should I do about bird flu with backyard chickens in California?
- The California Department of Food and Agriculture asks all poultry owners to practice biosecurity, such as limiting contact with wild birds and monitoring flock health, and to report sick birds. The CDFA bird flu line is 1-866-922-2473.
