//Quick answer
- New runs for ranges, dryers, pool heaters, fire pits and outdoor kitchens: permit usually required.
- The inspection generally centers on a pressure test of the new or repaired piping.
- The gas utility has its own requirements at the meter; the building department covers the house side.
- Gas line pricing is not published; call for pricing.
01Definition
Why are gas permits strict?
Because the failure mode is a leak inside a building. A permit creates an inspection where the new or repaired piping is pressure tested and the sizing, support, materials and shutoffs are checked before the appliance is connected. Nothing about a gas line tells you it is wrong until it leaks; the test is what tells you first.
What does the inspector generally check?
That the piping holds pressure for the test period, that the pipe size matches the total demand on the system, that the materials and fittings are the right type, that the run is supported and protected, and that each appliance has a shutoff. The details are the authority having jurisdiction's; confirm them with the building department for your address.
02When it applies
When is the utility involved?
At the meter. If the new load needs a larger meter or a pressure change, or if the utility has to shut off and restore service, their requirements apply on their side of the meter and the building department's on yours. Handling the gas company's requirements is part of a gas line job.
When is a permit usually not needed?
Connecting an appliance to an existing, correctly sized stub with a flexible connector generally is not permitted work. Anything that adds pipe, changes size or repairs a section usually is. Ask if you are unsure; there are many things that require a permit that you would not think of.
03What goes wrong
What goes wrong with unpermitted gas work?
An undersized line starves appliances and can make burners misfire. An untested joint leaks slowly into a closed space. Neither shows up on day one. The pressure test and inspection exist to catch both before an appliance is lit.
What about carbon monoxide alarms?
In Done-Rite's field experience, the most common thing an Orange County inspector flags on a permitted plumbing job is a missing carbon monoxide alarm, so the crew checks for one before scheduling the inspection. That is field experience with local inspectors, not a statement of what the code requires: the California Residential Code (R315.2.2) exempts installation, alteration and repair of plumbing systems from the carbon monoxide alarm trigger.

Common questions
Gas line work usually needs a permit. When a permit is required, Done-Rite pulls it.
The practical answer is that gas piping carries code, permit and safety consequences, and getting it wrong is expensive and dangerous. Whether an owner may do their own work is a jurisdiction-specific question for your building department.
