Tips

  • Water heater replacement is a flat $141.20 fee ONLY for tank-style units (electric or gas) — tankless water heaters and new gas piping instead fall under the plan-review category with valuation-based fees.
  • Residential vs. commercial backflow preventer permits carry different flat fees ($100 vs. $225) — confirm which category applies before applying.
