Gas Line Repair in Topanga, CA
42% of households in Topanga heat with bottled or tank propane. On propane there is no utility service line and no meter boundary — the tank, the regulator and the buried run to the house are all the property owner’s.
Read this first
No regulated utility service line is involved where the gas comes out of a tank, and 42% of homes in Topanga run on propane. The tank and the buried line from it are governed by the supply agreement rather than by a meter boundary, which changes who is responsible for what.
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 Topanga is supplied
A tank, a regulator, and buried line between them and the house. All of it is the property owner’s, and none of it sits under the federal service line definition that governs a mains connection.
That makes the buried run private buried line — which is exactly the sort a standard locate may not mark before somebody digs.

| Utility (mains) gas | 20% |

B25040 is a fuel count, not an infrastructure count. It tells you what burns in these houses, from which the arrangement follows — but it is an inference, not a meter reading. 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. Topanga sits 46 points below the state on mains and 40 points above it on propane. That distance from the state average is the whole argument for publishing a town figure at all.
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 how much gas work they actually do, not whether they can. Gas is separately licensed in most jurisdictions and plenty of capable plumbers do very little of it.

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. Gas is one part of what Topanga calls us about.
