Tips

  • Air Conditioning, Furnace Replacement, Gas Piping, and Hot Water Boiler/Heater all fall under the Town's 'Over the Counter One-Stop' flat-fee track ($150 base + $25 admin + $25 tech = $200 total each) rather than the full valuation-based Building Permit Fee schedule — this is typically faster and cheaper for straightforward like-for-like replacements.
  • Even a straight gas-furnace replacement in new construction should account for the Electric Ready code's dedicated branch-circuit and panel-space requirements for future electrification, per Appendix RM/CK.
