Cost guides for 2026 put new natural gas pipe at around $15 to $25 a foot once installed, while a short appliance hookup lands between $200 and $700. Those numbers cover the pipework alone. For the safety rules and the job itself, start at gas line plumbing, then come back here to price it.
How much is a gas line per foot?
Most 2026 guides settle on $15 to $25 a foot for new gas pipe. The spread depends on whether black iron or flexible CSST is used. Short appliance hookups usually total $300 to $800 regardless of footage. Because of that floor, a 5-foot job is not cheap per foot.
Material alone is a small slice: flexible tubing costs only a few dollars a foot, and labor, fittings, the shutoff valve, the permit, a pressure test make up the rest. CSST can come in lower because it needs fewer joints, but it also needs electrical bonding, which adds to the quote. Black iron suits exposed runs and is priced higher per foot.
What do appliance hookups cost?
Ballpark numbers from published guides: a gas range hookup $200 to $700 and a dryer $150 to $500. An existing stub-out behind a dryer cuts the job to $75 to $150. Converting an electric range to gas, or feeding a detached garage or outdoor kitchen, costs more and depends on the run.
Where the line is located inside the house matters as much as the length. A meter on the outside wall with a short run through the crawlspace is easy. A second-floor laundry, a finished ceiling to fish through, or a slab foundation that forces a route around the walls costs more. Add the flexible connector at each appliance.
Which extra charges show up on a gas quote?
Expect four: permit, pressure test, shutoff valve and, for outdoor runs, a trench. Permit fees are set by the city, and most plumbers roll them into the total. Passing inspection includes a leak test, and the plumber's time on testing goes on the quote.
Underground runs add the cost of a trench. Before anyone digs, DigAlert (811) must be called at least two working days ahead, and SoCalGas marks its lines for free. Hillside lots in Anaheim Hills and Yorba Linda add complexity, since slope and drainage affect where a trench can go.
Before accepting, check whether the quote lists:
- the city permit and inspection,
- the shutoff valve at the appliance,
- bonding for flexible tubing,
- patching of walls or concrete,
- hauling away old pipe.
Should the appliance installer handle the gas side too?
Bundling can save a second trip charge, so pairing a new range with its gas hookup makes sense. The piping itself belongs to a contractor (the Citrus Belt Plumbing home page shows how we arrange that) in California, and altering or adding a line triggers a permit through the city's Building Division. Skip any offer of an unpermitted gas line, whatever it saves.
Smelling rotten eggs inside means you walk out before anything else. Outdoors, call SoCalGas at 1-800-427-2200, plus 911 when anyone is endangered. Do not touch switches or strike a flame as you leave. Trial and error has no place with gas.
What will a seismic shutoff valve add to the bill?
Installed prices for seismic shutoff valves vary with the valve type and the layout of the meter and pipe, and some combination valves also react to a leak. No local price is published here, so the written quote sets the figure.
A seismic valve closes when shaking passes a threshold, while an excess flow valve responds to a sudden surge from a break, so they are not the same device. Installation normally needs a city permit and inspection. Background on the device sits in the earthquake valve guide, and what to do after one trips walks through the reset.
How do I pick a contractor for gas work?
Searches mentioning a "Gas Safe" register refer to a British scheme, and California has no equivalent by that name. What you want is a contractor whose California license number verifies on the CSLB site, with a named person pulling the permit. Gas jobs bill in the same hourly band as other plumbing in Orange County listings, about $100 to $200.
General rates are covered in the plumber price overview, and choosing a gas plumber covers selection. Repairing a weeping gas fitting is commonly billed at the hourly rate plus parts, with a minimum call charge.
Common questions
What is the flexible connector behind my range?
That short bendable tube joins a range or dryer to the fixed pipe in the wall. Swap it whenever the appliance moves, or once it kinks, corrodes or gets flagged as worn by a plumber. Parts are inexpensive. Fitting one to a new appliance is normally part of the hookup price.
Does natural gas line pipe come in different types?
Yes. Black iron is rigid steel that is threaded together, flexible CSST is corrugated stainless tubing that bends around obstacles, and some jurisdictions allow other materials. Which one applies depends on code and the route. The plumber picks it, and cost differences are in the table of extras above.
How long does a gas line job take?
One appliance close to an existing line may take about two hours. Fresh runs, trenches and inspections stretch it to a day or longer, and the inspector's calendar can add days before gas flows. The pressure test always comes first.
Could I do my own gas piping to cut the cost?
California expects a contractor to do gas piping, and a permit is part of it. Anaheim's published guidance allows an owner to take out a permit for a home they live in, yet a gas mistake risks an explosion, and the savings are small beside that. Hire it out and make sure the permit is on the paperwork.
