Full Breakdown
Municipal Code §129.0401–129.0410 requires a Plumbing/Mechanical Permit before any plumbing, heating, ventilation, air conditioning, or refrigeration work is installed, altered, or replaced. Limited exemptions cover minor repairs, like clearing stoppages or replacing fixtures in kind without touching supply or vent piping. The permit must be pulled before work starts; emergency work allows 2 business days to file. Each building needs its own permit for rough plumbing or HVAC work, except unoccupied accessory buildings. The Building Official may withhold gas or electrical meter approval until the structure passes occupancy inspection, and inspects all installations before sign-off.
Violations & Fines
Skipping the permit can trigger a stop-work order, denial of gas or electrical meter approval until occupancy is cleared, and mandatory correction with reinspection by the Building Official.
