Tips

  • The Town's Turn Around Times for Submittals document lists 'Engineering - Civil on-site (separate submittal)' at 8 working days; Mechanical is not separately broken out on that table from the Electrical/Plumbing/Engineering block, so the 8-working-day Engineering/civil figure is used here as the closest directly-published mechanical-adjacent MEP review figure — this should be reconfirmed with Willdan Engineering for a mechanical-specific number if greater precision is required.
  • A/C unit replacement is billed as a flat per-unit fee ($65 residential / $175 commercial) rather than valuation-based, per the Town's Fee Schedule.
