Data through July 2026 · updated 21 Oct 2026
1,416 building permits were issued in unincorporated Benton County from August 2024 to July 2026, about 708 a year. HVAC permits lead with 319, then garages, sheds & shade structures (267) and new homes (240). 86% were for homes. The county's file names contractors, but we don't rate, rank or profile firms from it: these pages show what was built, where and when.
Building permits the Benton County Building Department issues for unincorporated land only: Finley, Plymouth, Paterson, Whitstran and the rural areas around Kennewick, Prosser, Benton City and West Richland. Kennewick, Richland, West Richland, Prosser and Benton City issue their own permits and are not in this file; a Kennewick or Prosser mailing address here belongs to land outside those cities. Electrical permits are issued by the Washington State Department of Labor & Industries, not the county, so there are none in this file.
The permit file can't tell you who does good work. Ask for the contractor's license number and look it up at the Washington State Department of Labor & Industries contractor search, then ask the county whether they pulled the permit for your job.
Permits issued August 2024 through July 2026, every kind of work with 100 or more. Last 12 months on file is Aug 2025–Jul 2026. Homes is the share issued as residential permits.
