Tips

  • Furnace, boiler, air conditioner, and swamp cooler replacements use the Town's Flat Fee Schedule ($175-$275) rather than the valuation-based Building Permit Fee table — a simpler, cheaper path for like-for-like equipment swaps.
  • The Non-Structural Building Permit form itself states the Town has adopted the 2021 IBC and 2023 NEC — useful confirmation of currently-applicable code editions when filling out this specific form.
