Garage-sale signs are fine on your own property in Benton County, but directional signs staked in a road right-of-way, median, or on utility poles are prohibited and removed. A sign in a state highway right-of-way is a public nuisance WSDOT may clear without notice.
Benton County treats yard- and garage-sale advertising as temporary signage: a sign at the sale on private property is allowed without a permit, subject to reasonable size limits and prompt removal after the event. The problem is the directional signs people stake at intersections. Signs placed in a county road right-of-way, a median, or on utility poles and public property are prohibited and removed by county crews, and a sign in a state highway right-of-way is a public nuisance WSDOT may take down without notice under RCW 47.42.080. Inside Kennewick, Richland, West Richland, or Prosser, the city sign code applies instead.
Directional signs in a road right-of-way, median, or on utility poles are removed by county or WSDOT crews. Signs left up after the sale are treated as abandoned and removed.
