Chelan County, WA Parking Rules: Commercial & Oversized Vehicles (2026)

S. S. 97, SR 97A, SR 207 and SR 971. To qualify, the parcel must have existed in its current legal configuration as of August 20, 2024, meet the underlying zone's minimum lot size, and carry at least two hundred feet of continuous frontage on one of those routes. Subsection (14) of that section requires that parking of commercial vehicles used in the business be reasonably screened from all adjacent residentially zoned properties, on top of a matching ban on outdoor storage of materials or vehicles and machinery awaiting repair in subsection (13).

The same section caps the cumulative building footprint at ten thousand square feet or the zone's maximum lot coverage, whichever is smaller, bars new highway access and any use that would require access improvements, forbids on-site retail sales, and requires a lighting plan limited to indirect, shielded illumination of areas immediately around structures. This is a narrower rule than a general residential-district truck-parking ban: it applies specifically to a business already operating under a highway low impact conditional use permit next to residentially zoned land, not to trucks or commercial vehicles parked at an ordinary home. 93, and can add further screening or noise, light and impact mitigation under subsection (15).
