Backyard chickens in Modesto, California

Yes. Modesto's municipal ordinances permit residents to keep backyard hens, but only up to a set limit and with no roosters allowed. According to the city's fowl-keeping rules, residents may keep a maximum of twelve (12) hens per household, while roosters are prohibited in order to minimize noise disturbances to neighbors.

Coops and enclosures must be located at least 40 feet away from any residence (the keeper's own home or a neighbor's), per the city's zoning/animal-keeping guidelines. Chickens are generally associated with the R-1 residential zone requirements for animals and fowl. For final confirmation of permit status and any recent code updates, the city recommends contacting the Zoning Information office at (209) 577-5267.

Modesto sits in California's Central Valley, with long, very hot, dry summers (frequently topping 95–105°F) and mild, wet winters. Chicken keepers need to prioritize summer heat mitigation — shade, ventilation, and constant cool water — while winter cold stress is rarely a major concern. Tule fog in winter can reduce visibility and raise humidity around coops, so good drainage and ventilation help prevent respiratory issues.

Modesto's mix of urban, suburban, and adjacent agricultural land means backyard flocks can face raccoons, opossums, and skunks raiding coops at night, hawks (including red-tailed hawks) hunting by day, and coyotes and foxes wandering in from nearby orchards, canals, and open fields, especially at dusk and dawn. Secure, buried-wire coop construction and a covered run are strongly recommended.
