Full Breakdown
K of the Island County Code defines home occupations as accessory uses "permitted in any dwelling unit or accessory structure" in the county's rural and agricultural zones, and lists illustrative examples running from artists and authors to dressmakers, ministers' offices, a day care nursery, and wineries, cideries, distilleries or breweries without a tasting room. " The business must be owned and operated only by full-time residents of the parcel, retail sales are limited to items produced or accessory to services performed on site, and no mechanical equipment beyond normal residential use is allowed.
More than one home occupation can share a single parcel as long as the combined floor area and employee count stay within the limits, and staffing is capped at one full-time worker beyond the resident family. There is no separate permit fee schedule in this section; Planning and Community Development reviews compliance through the county's standard land use permitting process and can impose additional conditions to prevent the use from disrupting adjacent permitted uses.
Violations & Fines
A home occupation that exceeds 800 square feet or 50 percent of the dwelling's floor area, that is not operated by a full-time resident, that stores goods or equipment outdoors, or that shows any exterior sign of business activity violates section 17.03.180.K.2 and can lose its home occupation status. Planning and Community Development can order the use discontinued, deny future permits on the parcel, or require the operator to relocate to a properly zoned nonresidential parcel; continued noncompliance can escalate to formal code enforcement action.
