Rocklin, CA Right to Farm: Agricultural Zoning Protection (2026)

Rocklin's municipal code does not contain a right-to-farm ordinance shielding agricultural operations from nuisance claims; the city's protection for agriculture instead comes from its zoning. Chapter 17.32 establishes the RA-3 zone, a three-net-acre-minimum agricultural-residential zone, and § 17.32.010 lists permitted uses that include a single-family dwelling alongside agricultural crops, fruit trees, nut trees, vines, and horticulture, so growing and cultivating on an RA-3 parcel needs no discretionary approval. Section 17.32.020 adds a list of uses the RA-3 zone allows only with a conditional use permit: sale of agricultural products produced on the premises, greenhouses and nurseries (as long as they don't retail plants or products grown elsewhere), and stables and barns for keeping animals, but only on lots with no occupied single-family dwelling and only when a separate conditional use permit for keeping animals is also issued.

Minimum lot area in the RA-3 zone is three net acres under § 17.32.040, and lot coverage is capped at ten thousand square feet under § 17.32.050, with an additional five hundred square feet allowed by use permit. Rocklin also maintains larger-acreage agricultural-residential zones, RA-5 and RA-10, with parallel permitted-use structures scaled to bigger minimum lot sizes. A legacy R-A zone under § 17.30.010 still governs a shrinking number of parcels that predate the current title and will cease to exist once each remaining parcel is rezoned.

Property owners wanting to sell farm products, run a nursery, or keep livestock in an RA-3 zone need a conditional use permit from the Community Development Department and Planning Commission before doing so.
