Tips

  • Mechanical permits follow the same fee-calculation method as a standalone building permit when not bundled with one — confirm with the Building Division whether bundling your mechanical scope into a broader building permit changes your total cost.
  • Solid-fuel-burning and direct-vent appliances (fireplaces, stoves) require specific compliance details on the Mechanical Design Sheet — don't treat these as a standard HVAC swap.
