A quiet street. Somewhere on it, a permit was just filed.
Permit records, turned into work.
Cities publish every building permit. We read them every morning, work out who needs which trade next, and put it on a map, so you see the job before the competition does.

How it works
From a city spreadsheet to the job you call first.
Every morning the maps pull the newest permits from the city’s own records. They work out which stage each project is at and which trade it needs next, then group them by area so you can plan a route.
- Built from the city’s own permit records
- Refreshed every morning
- Shows which trade each job still needs
- No homeowner names or phone numbers
For builders, trades and ADU companies
