Tips

  • A Core and Shell buildout is valued at 70% of full new-construction valuation, while a pure Tenant Improvement (finishing an existing shell) is valued at just 30% — confirm which category your commercial project falls into before estimating fees, since it changes your Building Permit Fee substantially.
  • Commercial projects trigger Bennett-Watkins Fire Rescue's own separate, more extensive review (suppression/detection systems, water supply/cisterns) on top of the Town Building Department's own commercial plan review — budget for both processes running in parallel.
