Tips

  • Like-for-like water heater replacement (same type, size, location) does not require a permit — but the county still recommends verifying manufacturer specification compliance.
  • For gas line permits, be ready with BTU count, run length, and pipe size/type for the site plan — incomplete gas-line submittals are a common cause of review delay.
