Tips

  • Commercial and technically complex projects can have their Substantive Review extended from 105 to up to 165 working days by written/electronic agreement per A.R.S. §11-1605(I) — factor this into project timelines.
  • Temporary Certificate of Occupancy costs $500 (residential or commercial) and must be renewed every 30 days at the same $500 fee until the permanent C of O is issued.
  • Shell buildings (no interior trades, no designated tenant) are billed at a flat per-square-foot rate ($50/sq ft wood, $65/sq ft concrete/masonry) rather than full ICC valuation.
