Unincorporated Marin County allows backyard chickens under zoning rules: one hen per 1,000 square feet of lot area, up to 20 hens maximum, with coops up to 12 feet tall. Livestock keeping standards in the Development Code prohibit animals on slopes exceeding 50 percent.
Marin County's Development Code (Title 22) governs animal-keeping standards in unincorporated areas. Backyard chickens are permitted at a density of one hen per 1,000 square feet of lot area, up to a maximum of 20 hens, with chicken coops limited to 12 feet in height. Roosters are generally limited or restricted under nuisance noise rules. For larger livestock — horses, donkeys, mules, ponies — Title 22 standards apply, including a prohibition on keeping these animals on slopes exceeding 50 percent. Setback requirements for animal enclosures vary by zoning district.
Exceeding chicken limits, oversized coops, or keeping livestock on prohibited slopes are zoning violations handled by CDA Code Compliance. Enforcement begins with a notice of violation and correction deadline. Rooster noise complaints are enforced under Chapter 6.70.
