Summary
Unincorporated Cowlitz County's home occupation ordinance, CCC § 18.10.552, only lists a closed set of low-impact uses like artists, musicians, clergy and professional services as eligible home businesses, and bars any home occupation from emitting sounds, exhausts or vibrations beyond the property, standards a vehicle repair operation generally cannot meet without a different zoning classification.
A. The following occupations, when conducted in compliance with the standards set forth in subsection B of this section, shall be permitted as home occupations in all land use districts and shall not be required to obtain special use permit approval: 1. In home workspaces for artists, musicians, craft practitioners, clergy, professional services including classes led by such practitioners and other similar uses that meet the requirements of subsection B of this section; ... B. ... 2. ... The outward appearance of the structure shall not be altered or the occupation be conducted in a manner that would cause the premises to differ from its residential character either by the use of colors, materials, construction, lighting, or the emission of sounds, exhausts, or vibrations that carry beyond the premises;
Full Breakdown
552, the general home occupation ordinance for unincorporated areas. ' Auto repair is not on that list, and subsection B's standards work against it even if an operator argued it was a 'similar use': a home occupation cannot be conducted in a manner that would cause the premises to differ from its residential character through the emission of sounds, exhausts or vibrations that carry beyond the premises. Vehicle repair work, from running engines and power tools to venting exhaust, is difficult to keep within that boundary.
220(C) only permits it in the urban commercial (C-2) district 'where conducted entirely within a building,' not as a home occupation in a residential district. A resident who wants to run a repair business from a residential lot in unincorporated Cowlitz County therefore needs the property to carry, or be rezoned to, a commercial or industrial classification and go through the applicable permitted-use or special-use process rather than relying on the home occupation exemption.
Violations & Fines
Running a vehicle repair operation from a house or residential accessory building without meeting CCC § 18.10.552's incidental-use and no-off-site-emissions standards is not a lawful home occupation. Cowlitz County Building and Planning can cite the use as an unpermitted commercial operation in a residential district and require it to stop, relocate to a properly zoned property, or obtain the applicable land use approval.
