Gas Line Repair in Union City, CA
68% of households in Union City take mains gas. Two things follow: there is a buried line on the property, and somebody other than you is responsible for part of it.
Read this first
A buried service line and a meter sit on most properties in Union City, where 68% 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 Union City 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.

Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 21,202 occupied housing units. B25040 records what heats the house, which is the best available guide to whether a property has mains gas or a tank — it does not count service lines directly. 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. Union City sits 3 points above the state on mains and about level with it on propane. That is the gap a statewide number papers over, and the reason the figures above are this town’s rather than the state’s.
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
If any part of the job is in the ground, ask when they are calling 8-1-1 and whether a private line may be in the way. Both answers should come before the excavation, not during 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. Any Union City job, gas or otherwise, is routed from here.
