Before work starts, the permit must be prominently displayed at the job site after it has been authorized. Inspectors and officials are informed that your project is approved and under observation by this visible authorization.

4. Inspections During Construction

Permits frequently phone to perform multiple inspections at various stages of the project:

 

  • Rough-in inspections—plumbing, electrical, and HVAC—prior to wall completion
  • Framing inspections: before to insulation but following structural framing
  • Final inspections following the completion of all work

 

Every inspection verifies that the work complies with the code. Experienced contractors arrange work to pass the first time because failed inspections sometimes call for adjustments.
