How to pull the permit

  1. Put together a site plan showing where the work goes, with dimensions.
  2. Apply through the Avondale building department.
  3. Pay the permit fee when the permit is issued. Work done before that isn't covered.
  4. Book each inspection listed on the permit as the job reaches that stage.

Either of you can pull it. When a contractor does the work, it is normally their job.
