Summary
Auto repair and painting cannot be run as a home occupation anywhere in unincorporated Placer County. County Code Section 17.56.120(B)(2) puts auto repair or painting on the flat list of uses barred from home-based operation, regardless of zone district, lot size or acreage, alongside general commercial retail sales and other outdoor business activity.
Uses Prohibited. For guidance, the following and similar uses are not allowed as home occupations: commercial retail sales (except as allowed pursuant to subsection (C)(8)); auto repair or painting; any outdoor business activity not otherwise consistent with this chapter.
Full Breakdown
120 governs home occupations in every zone that allows them, and subsection (B)(2) puts auto repair or painting on the county's short list of uses that can never qualify, alongside unrestricted commercial retail sales and any outdoor business activity. The ban applies no matter how large the parcel is or how enclosed the work area might be, because home occupations must stay accessory to the residence under subsection (C). 120(C)(4) separately bars any mechanical equipment that creates noise, odor, glare, smoke or dust 'not normally associated with residential uses,' the same performance standard that would keep an auto repair operation off the approved list even without the explicit ban.
320 (Vehicle repair in residential areas), a separate provision limited to personal, noncommercial use; it does not authorize a paying auto repair or painting operation. 6 acres or more), three patrons on-site at a time, and 15 patron visits per day. An auto repair or paint shop run from a residence does not fit within any of these performance standards and cannot be permitted as a home occupation under this section, whether or not it is advertised or signed.
Violations & Fines
Operating unpermitted auto repair or painting from a residence is enforced as a zoning violation by Placer County code enforcement. Because Section 17.56.120 sets no specific penalty, the county's general penalty at Section 1.24.010 applies: a fine up to $1,000 per occurrence, up to six months in county jail, or both, charged as a misdemeanor or infraction, plus a civil penalty of up to $500 per day (capped at $100,000 per violation) and a court order to bring the property into compliance.
