Grant County, WA Garage & Yard Sales: Frequency, Duration & Permits (2026)

400. Subsection (a) defines a temporary outdoor event broadly as any social or cultural outdoor gathering lasting less than four cumulative weeks in a 12-month period that draws 250 or more people in a day. ' Unlike several neighboring exemptions on the same list, the garage-sale exemption carries no numeric limit: rummage and fundraising sales by nonprofits are capped at thirty days per calendar year, personal social events are capped at four occurrences per year, and Christmas tree lots are capped at thirty days, but garage and yard sales are simply exempt outright with no comparable cap written into the text.

That means a homeowner in the unincorporated county, whether near Moses Lake, Ephrata, or out in the Columbia Basin irrigation blocks, does not need a temporary use permit, does not pay a fee to Development Services, and faces no county-imposed limit on how many weekends a year the sale runs, so long as it stays on residential property and does not itself balloon into a 250-person, multi-week event covered by the broader definition. If a sale grows large enough to meet that threshold, or moves off residential premises onto commercial or vacant land, it falls out of the by-right exemption and into the discretionary or conditional review tracks the same section sets up for circuses, carnivals, and multi-day commercial sales.
