How to pull the permit
- Put together a site plan showing where the work goes, with dimensions.
- Apply through the Avondale building department.
- Pay the permit fee when the permit is issued. Work done before that isn't covered.
- 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.
