Yes, a plumber can run a gas line, and in California it has to be someone who holds a contractor license for it. Gas pipe is not a weekend project. One poor joint can seep into a wall cavity for months. Hence the permit, and hence the inspector. Ahead: the jobs we get asked about, the paperwork, the warning signs, and the figures national price guides publish. Browse everything else on the Del Amo Plumbing home page.
Can a plumber put in a gas line?
Yes. Running, extending, moving and capping gas piping for appliances is ordinary plumbing contractor work in California. The plumber works out pipe diameter from the combined appliance load, ties into an existing branch or the line after the meter, tests the new run under pressure, and sets up the city inspection. Homeowners and handymen should not do it themselves.
Typical jobs we get asked about:
- a stove or range feed, typically when going from electric to gas;
- a fireplace or fire pit, indoors or outside;
- a dryer hookup in a laundry room that has only a 240-volt outlet;
- a barbecue or outdoor kitchen drop from the house;
- a tankless water heater that needs a bigger pipe than the old tank did;
- relocating a line during a kitchen remodel, or capping one left over from a removed appliance.
Contractors who specialize in gas work know sizing tables, material choices and the way the city reads them. A plumber who rarely does gas may still be fine, but ask how many such jobs they do and who pulls the permit.
Who is responsible for natural gas lines?
In general SoCalGas looks after the service pipe as far as the meter, itself included. Everything downstream, from the meter through the house to each appliance, is the owner's. Torrance and most South Bay cities are served by SoCalGas, but check your own bill. Leaks past the meter are yours to repair, and the utility can shut service off until they are.
If you smell gas, the rule is the same whoever owns the pipe. Leave first. Once you are clear, SoCalGas answers at 1-800-427-2200, and lives at risk mean 911 as well. SoCalGas advises against switching lights or appliances, lighting flames or trying to fix a pipe yourself. On closing your meter, the company is firm: only after a smell, a hiss or other evidence of a leak, and with relighting left to its crews.
Landlords and tenants split duties by lease, but a gas smell is never something to wait on. Houses with a seismic trip valve should read resetting that valve after a quake.
What does gas line work cost in Torrance?
Fixr's national guide puts a gas line job at $500 to $2,000, averaging about $800, with new pipe at $15 to $25 per foot and a permit at $50 to $300. These are national guide figures, not Torrance quotes, and the written quote sets your price.
The numbers rise or fall with five things:
- Distance. Pipe is charged by length, which makes a patio run pricier than a hop to the kitchen wall.
- Access. Open crawlspace is easy. Finished walls, slabs and stucco mean cutting and patching.
- Pipe material. Black iron, flexible stainless tubing and CSST each carry different labor and fitting costs.
- Permit and inspection. Fees depend on the city. Torrance says plumbing permits are applied for online through Building and Safety.
- Appliance load. A new range may need only a branch. A tankless heater plus a fireplace may need a larger supply pipe throughout.
For a closer breakdown see gas line costs in Torrance. A per-foot rate is something we will not state, since the guides disagree; the plumber measures and quotes.
Is a permit part of this?
Almost always. Torrance's Building and Safety division puts pipes, fixtures, water heaters and sewer work under one plumbing permit. Inspectors normally look at new or changed gas pipe too, frequently running a pressure test before the drywall goes up. Ask Building and Safety at (310) 618-5910 to confirm the exact requirement for your job, because the city's FAQ does not spell out gas piping.
A skipped permit surfaces later, at a sale or a claim, and an untested joint is an unknown. Pulling the permit and booking the inspector is normally the contractor's task. Ask for the permit number before work starts. Our summary of residential gas piping codes explains what inspectors look at.
How do I recognize a dodgy gas plumber?
Watch for these gas-specific red flags: a contractor license number that cannot be confirmed with the state board, a quote silent on the permit, no talk of pressure testing, and flexible appliance connectors snaked through walls or hidden voids. Be wary too of anyone who pressures you to decide on the spot, or who asks for the full price before work starts.
Look the number up at the state contractor board (plumbing is C-36) and read what the record shows. Then insist on a written scope: which appliances, how many feet of pipe, which material, and whose job the permit is. A gas job that costs hundreds, not thousands, should still come with paperwork. If the plumber says no permit is needed, check with Building and Safety yourself.
What if a plumber or a digger hits a gas line?
People move away, nobody touches a switch, and SoCalGas is told by phone (1-800-427-2200) from a distance, and danger to anyone brings 911 in too. Do not try to squeeze, plug or wrap a damaged pipe. SoCalGas says gas escaping from plastic pipe can build static electricity that ignites it.
Most line strikes happen when someone digs without marking the route first. Call 811 before any digging in your yard, including for a fence post or a sprinkler line. For work inside walls, a plumber should know where gas runs before cutting.
Are there extra rules for a gas fireplace or a line to a stove?
A gas fireplace or log set needs the right size pipe, a shutoff within reach, and venting that suits the model. A stove line needs a proper shutoff and a flexible connector rated for the appliance. Both are specified by the manufacturer's installation manual and checked at inspection. A plumber reads that manual before the quote, not after.
A few practical notes. Capping a line is not just twisting a plug: it needs a proper cap on threaded pipe, tested for leaks. Moving a line during a remodel is cheaper before the walls are closed, so get the plumber in early. Planning a tankless heater? The pipe diameter is part of that bill too, as water heater replacement cost explains.
Common questions
What is the time commitment for a gas line job?
Hooking up one appliance may take only a few hours. Longer runs, finished walls or a vented fireplace stretch it toward a full day, and the city picks the inspection date. Ask for a time estimate and an itemized scope, and clear space around the meter and the appliance beforehand.
What should I get answered before I say yes?
Check the contractor's license with the state board before anything else. Then ask whether permit and inspection sit inside the price, what pipe material and diameter will go in, whether the run gets pressure tested, and who patches the drywall afterward. Get scope and price on paper. Straight answers are a good sign.
Should somebody be home while the gas work happens?
Yes. Someone should open the door, point to the appliance and shutoffs, and return at the end to check the result and let the inspector in. Gas will likely be off for a stretch, and pilot lights get relit at the end. A relative or property manager can stand in.
What is the highest paid type of plumber?
No sourced figure exists in our reading, so no guess either. Earnings usually climb with specialty and responsibility. Gas fitters, industrial pipefitters and plumbing contractors who own their firms tend to out-earn apprentices. For a homeowner, the useful question is not pay but whether the person at your door is properly qualified under state contractor rules.
Can I get a quote today?
On the quote page, name the appliance, its location and whether the walls are closed. Phones are covered weekdays, nine to five. After that a local plumber measures and writes the price down. A photo of the meter and of the appliance location speeds things along.
