A review of your building plans is required before a building, plumbing, mechanical, electrical, footing/foundation, or other permit will be issued. This review is to ensure your building plans meet municipal and national codes for life safety. After your plans have been reviewed the reviewer's comments will be sent to you.
ePlan allows building plans to be submitted electronically, improves the plan review cycle, reduces costs associated with obtaining residential and commercial construction permits, as well as supports green initiatives.
