Sacramento County Chicken Ordinance: Limits, Coops, and Permits

The Sacramento County chicken ordinance allows hens, roosters, ducks, and geese on residential lots of at least 10,000 square feet in the unincorporated county, with the exact number of birds set by a density formula tied to your parcel size and rear yard area.¹ Beyond the headcount, the rules dictate where the coop sits, how far it stands from neighbors, and how you maintain it. A single neighbor complaint can bring an inspection, so the details matter before you build.

Does the County Ordinance Even Apply to You?

These rules govern only unincorporated Sacramento County. If your address is inside the city limits of Sacramento, Elk Grove, Citrus Heights, Rancho Cordova, Folsom, or Galt, that city’s municipal code applies instead. The City of Sacramento, for instance, caps residents at three hens per lot, far tighter than the county.² If you aren’t certain which jurisdiction you’re in, check the Sacramento County Assessor’s parcel lookup or call the county planning department before you do anything else.

How Many Chickens You Can Keep

The lot minimum is firm: 10,000 square feet of residentially zoned property.¹ Clear that threshold and the density formula kicks in. You’re allowed one bird for every 1,000 square feet of total parcel area, or one bird for every 200 square feet of rear yard area, whichever number is lower.³

That “whichever is less” catch trips people up. A 10,000-square-foot parcel suggests ten birds. But if the rear yard is only 1,500 square feet, the rear-yard calculation caps you at seven. Run both numbers and go with the smaller one.

Roosters Are Treated Differently

Hens and roosters are not interchangeable under the ordinance. On the smaller qualifying residential lots, roosters are generally prohibited because of the noise. In several residential zoning designations (RD-4 through RD-7), a rooster requires a discretionary permit, typically a Minor Use Permit, and the allowed number may be capped at one or two birds even then. Larger, lower-density parcels face fewer restrictions, though the 20-foot setback from neighboring homes still applies.

If a rooster is part of your plan, confirm what your specific zoning designation allows with Sacramento County Planning and Environmental Review before you bring one home. A rooster kept without the proper permit is one of the fastest routes to a code enforcement complaint.

Coop Placement, Setbacks, and Size

Chapter 5 of the county zoning code governs how coops and aviaries are built on residential parcels.⁴ The requirements that matter most:

Chickens and their enclosures must stay in the rear yard. No coops in the front or side yard.³
The coop or fenced area must sit at least 20 feet from every neighboring residential dwelling.⁴
The structure must be at least 3 feet from interior side and rear property lines.⁴
Coops cannot exceed 8 feet at the peak of the roof.
The coop footprint cannot cover more than 30% of the required rear yard area.
The enclosure must provide at least 3 square feet per bird, up to a maximum enclosure size of 30 square feet.

Watch the cumulative accessory structure cap too. On lots under 20,000 square feet, all accessory structures combined, including the coop, cannot exceed 50% of the habitable floor area of your primary home. Lots of 20,000 square feet or more get a higher cap of 100%.⁴ An existing shed or detached garage eats into that allowance before you add a coop.

Maintenance, Noise, and What Triggers Complaints

Keeping a legal number of birds in a compliant coop still doesn’t shield you from a nuisance complaint. Sacramento County Code Title 6 requires animal owners to provide adequate food, water, and clean shelter at all times. That means keeping the coop free of accumulated droppings, storing feed in sealed containers so it doesn’t attract rats or flies, and preventing odors strong enough to reach your neighbors.

Noise sits in a separate ordinance. Sacramento County Code Section 8.08.050 prohibits animals from making loud or disturbing noises without provocation, including chronic vocalizations. The ordinance carves out an exemption for animal noises coming from areas where keeping fowl is otherwise permitted.⁵ Hen keepers on qualifying lots get some protection. A rooster crowing at 4 a.m. on a lot where roosters aren’t permitted gets none. Complaints are filed by calling 311 or through the county’s online reporting system.

Permits for Larger Flocks or Non-Standard Setups

If you want to exceed the baseline density formula or deviate from the standard rules in another way, you’ll need a discretionary permit from Sacramento County Planning and Environmental Review. The vehicle is usually an Administrative Permit for a modest expansion or a Minor Use Permit for more significant departures.

The application typically requires a site plan showing the proposed coop location relative to property lines and neighboring structures, along with your parcel dimensions and zoning designation. Renters need written consent from the property owner. Applications go through the planning office, and the review period generally includes notification to adjacent neighbors, who can submit feedback that affects the outcome. Fees are published on the Sacramento County Land Use Regulation Library website and change with periodic updates, so pull the current schedule before filing.⁶
