Summary
Snohomish County bars automobile, truck and heavy equipment repair as a home occupation. SCC 30.28.050(3)(g) prohibits fueling, maintenance, repair, auto-body work or painting for home occupations run from an accessory building or garage, and (4)(o) extends the same ban to rural and resource-based home occupations, with a narrow carve-out for repairing vehicles used in that specific business.
(3)(g) The following activities, including any similar activities, are prohibited as home occupations: minor or major automobile, truck or heavy equipment fueling, maintenance or repair; auto-body work or painting; parking or storage of heavy equipment; and any Group H occupancies as defined in the building code except for woodworking and spray finishing in conjunction with woodworking activities; ... (4)(o) The following activities, including any similar activities, are prohibited as rural home occupations: processing of minerals, sawmills, retail or wholesale sale of motor vehicles, major and minor automobile repair (except repair of vehicles and equipment used in a rural residential based or resource-based home occupation business), motor vehicle body work or painting, and any Group H occupancies as defined in the building code, except for woodworking and spray finishing in conjunction with woodworking activities.

Full Breakdown
050(3)(c). Within that framework, subsection (3)(g) flatly prohibits, as home occupations, 'minor or major automobile, truck or heavy equipment fueling, maintenance or repair; auto-body work or painting; parking or storage of heavy equipment,' along with Group H hazardous occupancies, though it carves out woodworking and spray finishing tied to woodworking. The same ban carries into subsection (4), which covers resource-based and rural home occupations tied to agriculture, forestry, or rural residential land uses. Subsection (4)(o) prohibits 'major and minor automobile repair' and 'motor vehicle body work or painting' as rural home occupations, but unlike (3)(g) it includes a limited exception: repair of vehicles and equipment actually used in that rural residential or resource-based business itself is allowed, so a landscaping or farming operation can service its own trucks without that work counting as a prohibited home occupation.
Outside that narrow exception, opening any kind of paid auto repair, body shop, or fueling operation out of a home garage or accessory building in unincorporated Snohomish County is not permitted under the home occupation provisions regardless of lot size, and no home occupation approval process can authorize it because the activity is excluded outright rather than merely restricted. 120, not as an accessory home occupation.
Violations & Fines
An unauthorized home-based auto repair operation is enforced as a Title 30 land-use violation under SCC chapter 30.85 by the Department of Planning and Development Services' code enforcement division, which can issue a warning notice, citation, or notice of violation. Monetary penalties under SCC 30.85.170 run from $500 for a non-commercial violation up to a $10,000 cap, or from $1,500 up to $25,000 for a commercial operation, with repeat violations doubled under SCC 30.85.280. The property owner has 14 calendar days to appeal a notice of violation to the hearing examiner under SCC 30.85.190.
