Gas Line Repair in Larkspur, CA
Larkspur is a mains gas town — 61% of households heat with utility gas. The useful thing to know before anything goes wrong is where the utility’s responsibility stops.
Read this first
A buried service line and a meter sit on most properties in Larkspur, where 61% of homes are on mains gas. Federal rules end the utility's service line at the meter outlet, so everything downstream of the meter is the owner's to maintain and repair.
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 Larkspur is supplied
The meter is doing two jobs: measuring gas, and marking where the federally regulated line stops. The second is the one that matters when something fails.
Buried customer piping past the meter — out to a garage, a grill, a generator — is the owner’s, and it is easy to forget it exists until somebody digs.

|---|---|
| Utility (mains) gas | 61% |

Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 3,431 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. Larkspur sits about level with the state on mains and about level with it on propane. Averages are where this kind of difference disappears. The figures on this page are the town’s own for that reason.
Before anyone digs on the property
Digging is the risk, not age or material. PHMSA names excavation damage as the leading cause of pipeline incidents and puts a caller’s chance of avoiding one at 99 percent. 8-1-1 is nationwide, toll-free, and costs nothing.

What to ask whoever quotes it
Ask how the work will be tested and what happens at the end of it. An inspection on gas work is normal rather than a complication, and a contractor who treats it as one is telling you something.

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. Other Larkspur requests are covered by the same line.
