Gas Line Repair in Pasadena, CA
Century-Old Buildings, Present-Day Gas Loads
Pasadena asks a lot of old pipe. The Craftsman bungalows near the Gamble House and the commercial buildings of Old Pasadena went up a century or more ago, and original piping is still in service in many of them. Rooter & Plumbing Masters carries out gas line repair in Pasadena, CA in both: tracing and repairing leaks, replacing lines that have corroded beyond repair, and running new ones for the kitchens, water heaters and outdoor features being added. All of it is pressure tested before the gas is turned on again.
Suspect a leak? Then nothing on this page matters until you are outside. Leave at once, do not switch anything on or off, do not light anything, and call SoCalGas at 1-800-427-2200 or 911 from the street. Pasadena runs its own water and power utility, but gas here is SoCalGas, and it is their crew that shuts the supply and secures the building. With that done, our plumbers, on call around the clock, find the fault and repair it.

Plumbing Tips
Gas Line Work Particular to Pasadena
Old buildings and new appliances meet in three common ways here:
A range or cooktop upgrade in a Craftsman kitchen — the house usually sits on a raised foundation, the original threaded line runs through the crawlspace, and the new range wants more gas than the old one. We inspect the run from below, replace what is corroded and bring a properly sized line up to the kitchen.
A restaurant fit-out in Old Pasadena or on South Lake Avenue — a new tenant, a new kitchen layout and a building whose piping predates everyone involved. We test the existing gas line before equipment is planned around it, and repipe to the new layout where it will not serve.
Capped and abandoned lines — generations of heaters and appliances have come and gone in these houses, each leaving a stub behind. A poorly capped stub is a leak waiting to be found; we remove or properly cap them and test the system.
Does Pasadena’s electrification ordinance stop me from adding a gas line?
For most of the work we do, no. The ordinance, adopted in 2022, was written for newly constructed multi-family, mixed-use and commercial buildings and for large additions to commercial ones; single-family homes, accessory dwelling units, food service kitchens and alterations to existing buildings were exempt. Rules like this change, so we confirm the current position with the Permit Center when the permit is applied for.
Which Pasadena office issues gas line permits?
From the Building & Safety Division, through the city’s Permit Center on North Garfield Avenue. A new or extended line, or a replaced run, generally needs a plumbing permit and an inspection. You may apply as the owner. If you prefer that we apply, the permit costs what the city charges plus our administrative fee, and the estimate says so.
