Where these numbers come from
Build Radar reads the public permit records and the plan sets the city posts, and its plan search finds the words on every page. Each project here was found by that search and read: code text, legends, abbreviation lists and "X or Y" options do not count. Only projects in progress count - not finished, not cancelled, not a year old with no inspection - and only the ones that trade sees in the app.
Each number is rounded down to the nearest 10, and a number under 10 is not shown. These counts are from Nov 4, 2026. 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.
