Summary
Island County allows small auto repair shops as a "home industry" on Rural, Rural Agricultural, Rural Forest or Commercial Agricultural land under Island County Code section 17.03.180.J, which lists "Auto repair with a maximum of two (2) service bays" among its illustrative uses, subject to a minimum 2.5-acre parcel and a 50-foot setback from every property line.

Full Breakdown
5 acres if the shop employs no more than two non-family workers on site, rising to a 5-acre minimum if more than two are employed, and the owner must sign an agreement acknowledging the standards and consenting to shut down or conform if the county finds a violation. 15 is required, all repair work must occur inside an enclosed structure or be fully screened from view, and outdoor storage of vehicles, parts or supplies can trigger additional conditions. Floor area is limited to 800 square feet or 50 percent of the dwelling as a Type II application; a Type III application is needed for anything larger, up to a 4,000-square-foot cap that is waived only on parcels of 10 acres or more.
The minimum building setback for the repair structure is 50 feet from every property line, which the approving authority can increase to limit impacts on neighbors, and the business must relocate to a nonresidential zone if it later exceeds these thresholds.
Violations & Fines
Running more than two service bays, employing more than the permitted number of non-family workers without the larger 5-acre minimum parcel, or storing vehicles and parts outside without required screening violates section 17.03.180.J and can result in code enforcement action by Planning and Community Development. Under the signed home industry agreement required at approval, the county can order the business "discontinued or brought into strict conformance," and repeated or unresolved violations can force relocation to a properly zoned nonresidential parcel.
