Summary
A home occupation in unincorporated Island County cannot bring more customer or client traffic than the surrounding zone would normally see. Island County Code section 17.03.180.K.2.j bars any home business from generating "traffic in excess of that normally generated by typical uses found within the particular zone," and caps outside staff at one non-family employee working on site.
K.Home occupation standards. Home occupations are accessory to the primary residential use and are permitted in any dwelling unit or accessory structure. ... j.The proposed use shall not generate traffic in excess of that normally generated by typical uses found within the particular zone.k.The home occupation does not employ on-site or report to work on-site, more than one (1) full time person other than those of the immediate resident family.
Full Breakdown
K. 2, which requires the operation to be clearly incidental and secondary to residential use, limits floor area to 50 percent of the dwelling or 800 square feet (whichever is smaller), bars outside storage or exterior signs of the business, and limits on-site staffing to one full-time employee beyond the resident family. Because the traffic cap is judged against what the particular zone "normally" sees, a home business in a Commercial Agriculture or Rural Center parcel, where mixed-use and farm traffic is already common, is measured differently than one in a low-density Rural Residential subdivision.
Planning and Community Development reviews home occupation applications and can attach traffic-related conditions, such as limiting hours of customer visits or requiring off-street parking, if a proposed use would otherwise exceed the zone's normal traffic pattern. There is no fixed numeric trip cap in the code; compliance is judged case by case against the surrounding zone's typical traffic character.
Violations & Fines
A home occupation that draws more vehicle traffic than the zone normally sees, that employs more than one non-family worker on site, or that shows exterior signs of commercial activity is out of compliance with section 17.03.180.K.2 and can have its home occupation approval revoked by Planning and Community Development. Continued operation after a violation notice exposes the owner to code enforcement action and potential civil penalties under the county's general enforcement provisions, plus a requirement to relocate the business to a nonresidential zone.
