Gas Line Repair in Concord, CA
Utility gas heats 64% of homes in Concord. That puts a buried service line and a meter on most properties here, and puts the boundary between the two sides of the system exactly at the meter.
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 Concord, where 64% 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 Concord is supplied
The meter is the boundary the federal rules draw: a service line terminates at the meter outlet, or at the connection to customer piping if that is further downstream. Everything past it is customer piping.
Ownership and maintenance responsibility follow tariff and state regulation rather than that definition, and they do not always land in the same place. Ask where your utility’s responsibility ends before you need to know.

What B25040 measures is the heating fuel, not the connection. It is the closest published proxy for whether there is a buried service line here, and it is a proxy. 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. Concord 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
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 whether the job needs a permit and who is pulling it. Gas work is separately permitted in most jurisdictions and the answer should not be you.

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. Any Concord job, gas or otherwise, is routed from here.
