Summary
Unincorporated Multnomah County bars any repair or assembly of motor vehicles as a home occupation, no matter which home-occupation tier the business is registered or permitted under.
No repair or assembly of any motor or motorized vehicles. A motorized vehicle includes any vehicle or equipment with an engine including automobiles, motorcycles, scooters, snowmobiles, outboard marine engines, lawn mowers, and chain saws.
Full Breakdown
If you run a business from a dwelling or accessory building in unincorporated Multnomah County, county code flatly prohibits repairing or assembling motor or motorized vehicles as part of that home occupation. The ban is written identically into the standards for all three home occupation tiers (Type A, Type B, and the conditional-use Type C), and it defines "motorized vehicle" broadly enough to reach a home mechanic's whole toolkit: automobiles, motorcycles, scooters, snowmobiles, outboard marine engines, lawn mowers, and chain saws. There is no permit path around it inside the home-occupation framework itself. This applies only outside the cities of Portland, Gresham, Troutdale, Fairview, and Wood Village, which enforce their own municipal codes.
Violations & Fines
Operating a home auto repair business violates the home occupation approval and can be enforced as a zoning code violation by Multnomah County Land Use Planning; a Type C permit found out of compliance can also be revoked.
