Gas Line Repair in Mission Viejo, CA
In Mission Viejo, 78% of homes are on mains gas. Every one of them has a service line under the ground between the street and the meter, and part of it belongs to somebody else.
Read this first
A buried service line and a meter sit on most properties in Mission Viejo, where 78% 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 Mission Viejo 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. Mission Viejo sits 12 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
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. Other Mission Viejo requests are covered by the same line.
