Based on Bethlehem's local building codes, you'll need a permit when:
Extending an existing gas line to serve a new appliance requires a gas permit. This includes running new branch lines for gas dryers, gas ranges, water heaters, fireplaces, outdoor fire pits, pool heaters, standby generators, and outdoor kitchens. A pressure test and inspection are required before concealing any piping.
Outdoor gas lines for fire pits, grills (hard-piped), pool heaters, patio heaters, outdoor kitchens, and generators require a gas permit. Underground gas piping must be polyethylene (PE) per ASTM D2513, buried at least 12 inches deep, with transition to metallic pipe before any building entry.
A new gas service line from the meter requires a gas/plumbing permit. The installation must meet IRC Chapter 24 (Fuel Gas) / IFGC Chapter 4 requirements, including pipe sizing, pressure testing at 3 psig minimum for 10 minutes, and inspection before the piping is covered or concealed. A licensed plumber is required in virtually all states.
These gas line projects are typically exempt in Bethlehem:
Relighting a pilot light or adjusting an existing appliance's shutoff valve does not require a permit. Replacing a listed flexible appliance connector at an existing appliance is also typically exempt. Any work involving new piping, pipe extension, or appliance connections requires a permit.
