Gas Line Repair in Pasadena, CA
Most of Pasadena is on the gas main: 68% of households. That means a meter on the wall and a service line under the ground, and a boundary between them that federal rules put in a specific place.
Read this first
The utility's regulated line ends at the meter outlet and the piping beyond it belongs to the property owner. That boundary decides most gas line questions in Pasadena, where 68% of households heat with utility gas and a buried service line runs from the street on most properties.
Source: US Census Bureau, American Community Survey table B25040; the service line boundary is 49 CFR § 192.3.
If you smell gas right now
Leave the building on foot. Do not use a phone or a light switch inside. Call 911 and your gas utility from somewhere else, and do not call us — we are a referral service, not an emergency line. The full list, in order.
How Pasadena is supplied
Two questions hide behind one. Where does the regulated line end — the federal answer is the meter outlet. And who pays for a repair on either side of that — which is tariff and state regulation, and varies.
The second one is the one that costs money, and it is answered by your utility rather than by any rule you can look up.
| Households in Pasadena | Share |
|---|---|
| Utility (mains) gas | 68% |
| Bottled or tank propane | 1% |
| Electricity | 28% |
| Fuel oil and kerosene | under 1% |
| Wood and everything else | 2% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 62,683 occupied housing units. The table counts heating fuel rather than pipework. A house on mains gas almost certainly has a service line; the Census does not say so directly and neither do we. Service line definition: 49 CFR § 192.3, via PHMSA interpretation PI-12-0003.
Across California as a whole, 65% of households are on mains gas and 2% on tank propane. Pasadena sits 3 points above the state on mains and 1 point below it on propane. That spread is what a state average hides, and it is why this page carries the town’s own figures rather than inheriting them.
Before anyone digs on the property
Before any digging — a fence post as much as a foundation — call 8-1-1. It is a nationwide toll-free number, it costs nothing, and PHMSA puts the chance of avoiding an incident afterwards at 99 percent.

What to ask whoever quotes it
Ask what they will do about the existing load. Adding an appliance changes what the existing pipe has to deliver, and sizing is a calculation against the whole system rather than the new run alone.

Checking a plumber in California
California licenses are issued by the Contractors State License Board, which publishes a public search you can use before work begins. California licenses the C-36 plumbing contractor; there is no state journeyman license.
Gas work is separately permitted and separately licensed in most jurisdictions, so ask specifically about gas rather than plumbing in general.
For repair work, not for a suspected leak.If you can smell gas, leave and call 911 or your utility from outside; this is the wrong number for that. For everything else — a line, a meter, an appliance connection — we will route you to a contractor covering your area, free of charge to you. Non-emergency work in Pasadena goes through this number as well.
