Gas Line Repair in San Anselmo, CA
76% of households in San Anselmo heat with utility gas, which means a buried service line runs from the street to a meter on most of these properties. Where that line ends is a federal definition, and it decides who repairs what.
Read this first
A buried service line and a meter sit on most properties in San Anselmo, where 76% 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 San Anselmo is supplied
Under 49 CFR § 192.3, a service line ends at "the outlet of the customer meter or at the connection to a customer’s piping, whichever is further downstream". Upstream of the meter is the operator’s regulated line. Downstream is customer piping, under local code.
That is where the regulated line stops. Who pays is a separate question set by tariff and state regulation, and it is worth asking your utility rather than assuming.

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. San Anselmo sits 10 points above the state on mains and 1 point below it on propane. The state number would tell you something true about the state and very little about here, which is why it is not the number above.
Before anyone digs on the property
8-1-1 is free and nationwide, and PHMSA gives callers a 99 percent chance of avoiding an incident, injury or worse. Ask them what they will and will not mark: privately owned buried lines on your own side of the meter frequently are not covered.

What to ask whoever quotes it
Ask them to describe the fault before they price it. "The line needs replacing" is not a diagnosis, and on a buried run the difference between one damaged point and a line at the end of its life is most of the cost.

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. We serve San Anselmo for plumbing that has nothing to do with gas.
