Benton County sets maximum building height by zoning district in Title 11, measured to the highest point of the roof. Inside Kennewick, Richland, West Richland, Prosser, and Benton City, each city's own zoning code fixes the height limits instead.
Building height in unincorporated Benton County is governed by the district standards in Title 11 of the Benton County Code rather than left unregulated. Height is measured from grade to the highest point of the structure, and customary projections such as chimneys, antennas, and farm silos are handled separately. Agricultural and rural districts allow the tall accessory buildings that ranching and vineyard operations need. Near the Richland Airport and the Tri-Cities Airport across the river in Pasco, FAA airspace surfaces can further limit height. Kennewick, Richland, West Richland, Prosser, and Benton City each set their own height limits within city limits.
Exceeding the district height limit violates Title 11. Benton County Planning can withhold permits and require the structure be lowered. Added height needs a variance from the county hearing examiner.
