How to use this page

A comparison is a starting point, not a clearance.

  1. 1Choose the state where the work will occur and the trade that matches the project scope.
  2. 2Read the state/trade record for the specific requirement and its linked board information.
  3. 3Confirm current requirements and a contractor’s status directly with the relevant public authority before hiring or starting work.

What the counts do not answer

The rankings do not assess a contractor, predict project quality, or replace local permitting rules. Requirements can vary by classification, project and municipality, and the underlying record may change after its shown vintage.
