From our cross-city data studies: the same measure, read the same way, for every city we cover.
Permit statistics for other places in the Tri-Cities. Each permit office keeps its own file, so the numbers are not added together.
Source: City of Kennewick EnerGov public permit layer (Public/EnerGovPublicInspection, EnerGovPermits), behind the city's Permit & Plan Explorer, read 19 Oct 2026. We count permits issued October 2024 through September 2026; denied and withdrawn permits are left out.
Building, mechanical, plumbing, sign and fire-system permits the City of Kennewick issues inside the city limits only. Richland, Pasco, West Richland and unincorporated Benton County run their own permit offices and are not in this file. Public works, utility-connection, right-of-way and grading permits are left out. Electrical permits in Washington are issued by the state Department of Labor & Industries, not the city, so they are not 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 →
