Chelan County, WA Home Business: Zoning & Home Occupation Permits (2026)

230 sets nine minimum conditions for any home occupation in the unincorporated county. The use cannot occupy more than 25% of the dwelling's total floor area and must remain secondary to the home's primary residential use (subsections (1)-(2)). Only one person outside the resident family may be employed on-site (subsection (3)). 92's sign standards (subsection (4)), and the business may not have a separate exterior entrance other than through the dwelling itself, except where law requires one (subsection (5)). The code bars exterior display or storage of materials (subsection (6)) and limits stock-in-trade to goods produced on the premises or items stored entirely indoors for off-premises sale (subsection (7)).

Equipment or materials that create vibration, noise, dust, smoke, odor, or interference with radio or television reception detrimental to the residence or neighbors is prohibited (subsection (8)), and deliveries requiring commercial vehicles with more than two axles are barred (subsection (9)). A home occupation may operate out of an accessory building if at least two parking spaces beyond those required for the dwelling are provided and the building used is no larger than 500 square feet (subsection (10)). These standards apply uniformly across the county's rural residential and resource zones under Title 11 and are reviewed by Community Development at permit application; violations are handled through code enforcement under Title 16, which can require correction or revoke the underlying land use approval for the home-based use.
