From our cross-city data studies: the same measure, read the same way, for every city we cover.
HVAC permits for other places in the Tri-Cities. Each permit office keeps its own file, so the numbers are not added together.

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