Political signs are allowed on private property throughout Benton County with no permit, protected as free speech. Signs staked in a county road or state highway right-of-way are prohibited — WSDOT removes them without notice — and county guidance requires removal within 10 days after the election.
In unincorporated Benton County, campaign and political signs are permitted on private property without a permit, and content-based limits are unconstitutional after Reed v. Town of Gilbert (2015). The catch is placement off your land: a sign in a state highway right-of-way is a public nuisance that WSDOT may remove without notice under RCW 47.42.080, and signs in county road rights-of-way, medians, and traffic-island planting areas are prohibited and removed. County guidance requires taking political signs down within 10 days after a voting day. Kennewick, Richland, West Richland, and Prosser apply their own municipal sign codes.
A political sign in a state highway or county road right-of-way is removed by WSDOT or county crews. Signs left up more than 10 days after the election are removed as abandoned.
