Washington building permits

Where these numbers come from

Build Radar reads the public permit records of each county and city - the permits, their status and their inspections - and puts every new building on one map. These counts were made on Oct 21, 2026.

Each number is rounded down to the nearest 10, and a number under 10 is not shown. Finished houses, cancelled or expired permits and permits a year old with no recent inspection are not counted. Each dot on the map is moved to its own spot inside a square about 450 m across, so no dot sits on a house.

Inside the app each project shows its build stage, the builder, the plans when the county posts them and the phone numbers on file.
