Full Breakdown
Sonoma County Code § 26-88-121(b)(3) lists 'automotive and other vehicle sales, repair, services, painting, storage, or upholstery, or the repair of engines, including automobiles, boats, motorcycles, trucks, or recreational vehicles' among the business activities flatly barred from operating as a home occupation in unincorporated county territory. The same ban carries over to live/work units (§ 26-88-122), work/live units (§ 26-88-124), and mixed-use developments (§ 26-88-123). The rule applies only outside the county's nine incorporated cities. Santa Rosa, Petaluma, Rohnert Park, Windsor, Healdsburg, Sebastopol, Cotati, Cloverdale, and the City of Sonoma each set their own home-based business rules.
Violations & Fines
County code enforcement can issue a stop-work or cease-operation order and administrative citations under § 1-7.6 for running a prohibited home occupation; the underlying zoning clearance can also be revoked.
