The following uses, by the nature of the investment or operation involved, have a pronounced tendency, once started, to rapidly increase beyond the limits specified above for home occupations and thereby impair the use, value and quiet enjoyment of adjacent residential properties. Therefore, the uses specified below and other similar or comparable uses shall not be permitted as home occupations:(1)Automobile, vehicle, lawn mower, and large appliance repair or service;

Full Breakdown
The county's home occupation ordinance does not merely limit auto repair at a residence, it forbids it outright. 072(C) opens by explaining why: uses on the prohibited list have, in the county's own words, a pronounced tendency, once started, to rapidly increase beyond the limits specified above for home occupations and thereby impair the use, value and quiet enjoyment of adjacent residential properties. Automobile, vehicle, lawn mower, and large appliance repair or service tops that list, followed by medical and dental offices, freight and trucking operations, vehicle painting, restaurants, tool rental, and welding or machine shop work.
The ban applies regardless of scale: there is no threshold for occasional versus regular repair work, and no exception for repairing only the household's own vehicles for pay or working out of a garage rather than a dedicated shop. 072(A) that cap commercial-grade equipment and commercial vehicle storage for occupations that are otherwise allowed; auto repair does not get to that stage because it is excluded as a use in the first place. A resident who wants to run an auto repair business from a residential property in the county has to locate it in a business, commercial, or industrial district where standalone repair uses are permitted under the district's own use table, not under the home occupation provisions.
Violations & Fines
Running an auto repair operation as a home occupation is a zoning violation under section 154.999, since the use itself is prohibited outright rather than merely restricted. The zoning administrator can issue a notice of violation and, if the repair activity continues, a citation with a fine from the ordinance's fee schedule, due within 14 days in a residential district; each additional day of operation counts as a separate violation, appealable to the Board of Zoning Appeals.
