What this page can and can't show

  • ✓Permits the county issued, by kind of work, month and ZIP code.
  • ✓Which permits finished or are still open.
  • ✓What the job was declared at on the permit.
  • ✓Which contractors filed the most permits (volume, not quality).
  • Who does good work. The county's file names contractors, but we don't rate, rank or profile firms from it.
  • How long a permit takes to final. The file has too few final dates.
  • Street addresses or owners. We publish counts and permit rows without them.

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.

Hiring someone here?

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.

How these numbers are made

Source: Benton County Building Permits (ArcGIS Online: Building_Permits_Assessor_VIew), read 21 Oct 2026. We count permits issued August 2024 through July 2026; denied and withdrawn permits are left out.

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 county's file names a contractor on about three in four recent permits; most of the rest are owner-builders. Older permits name one far less often.
  • The value is the job valuation the county records for its permit fee.
  • The window ends in July 2026: most permits applied for since then had no issue date yet when the file was pulled.
  • A completion date is filled on too few permits to time them, so we show which permits the county marks complete or closed but not how long they took.
  • Recent permits carry no parcel number, so the file can't be placed by ZIP code.
  • The county files its permits under short codes; SOB (small mechanical, plumbing and other jobs) and DRA (home remodels and additions) are split into kinds of work by their descriptions, and SFD and FAS (manufactured homes) count as new homes.

Counts are permits, not jobs: one job can need several permits. Nobody paid to be on this page and nobody can. Sources and definitions →
