Summary

In Stanislaus County's Rural Residential (R-A) district, any building used for keeping livestock or poultry must sit at least fifty feet from any public street and forty feet from any adjacent property, a setback set out at Zoning Code Section 21.24.080(D) that is far stricter than the five-foot side-yard rule that applies to ordinary accessory buildings.

City-specific rules exist: Modesto has its own chickens & livestock rules that differ from Stanislaus County's county-level regulations. If you live in Modesto, check the city-specific page instead.

Buildings for Keeping Livestock or Poultry. Not less than fifty feet from any public street, measured from edge of pavement, nor less than forty feet from any adjacent property.

Full Breakdown

080 lays out the yards and open-space rules for the county's Rural Residential district, and subsection (D) singles out one use for its own, larger buffer: 'Buildings for Keeping Livestock or Poultry. ' That is roughly ten times the ordinary five-foot interior side- and rear-yard setback the same section sets for a standard R-A home in subsection (B), reflecting the county's judgment that barns, coops, and stables need more separation from neighbors and roadways than a garage or shed. 080(D) instead governs where any qualifying livestock or poultry structure can physically be placed once that threshold analysis is done.

060(F) imposes on parcels fronting specific county roads such as McHenry Avenue or State Highway 108. Because the R-A district borders both the A-2 general agriculture district and denser residential zones, the fifty-foot street setback and forty-foot property-line setback are the tools the county uses to keep barns and stables from crowding an adjoining home.

Violations & Fines

Erecting a livestock or poultry building closer than fifty feet to a public street or forty feet from an adjacent property line without approval is a zoning violation under Stanislaus County Code Section 1.36.010, punishable as a misdemeanor by a fine of up to one thousand dollars, up to six months in county jail, or both, and the planning department can require the structure be relocated or removed to bring the parcel into compliance.

Frequently Asked Questions

How far from the road must a barn or chicken coop be in unincorporated Stanislaus County?
At least fifty feet from any public street, measured from the edge of pavement, under Section 21.24.080(D) of the Rural Residential district regulations: far more than the standard building setback that applies to a garage or storage shed.
What is the required distance from my neighbor's property for a livestock building?
Forty feet from any adjacent property line, per the same Section 21.24.080(D), which applies specifically to buildings used for keeping livestock or poultry rather than to ordinary residential accessory structures.
Does this setback apply everywhere in the county?
The fifty-foot street and forty-foot property-line setbacks are set in Section 21.24.080, which governs the Rural Residential (R-A) district specifically; other districts such as General Agriculture (A-2) carry their own yard and building-site rules under separate sections of Chapters 21.20 and 21.24.
