Gas Line Repair in Aliso Viejo, CA
Most of Aliso Viejo is on the gas main: 68% of households. That means a meter on the wall and a service line under the ground, and a boundary between them that federal rules put in a specific place.
Read this first
Responsibility changes hands at the meter outlet. The line under the ground between the street and the meter is the utility's up to that point, and the yard line and house piping after it are the property owner's. 68% of homes in Aliso Viejo heat with utility gas.
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 Aliso Viejo is supplied
Everything upstream of the meter outlet is the operator’s service line under 49 CFR § 192.3. Everything after it is customer piping under local code. That single point is what a contractor establishes before quoting.
It is also why the answer to "is this my problem" is sometimes no, and why it is worth asking before assuming it is yes.

| Utility (mains) gas | 68% |

Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 20,226 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. Aliso Viejo sits 3 points above the state on mains and about level with it on propane. That distance from the state average is the whole argument for publishing a town figure at all.
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 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 Aliso Viejo job, gas or otherwise, is routed from here.
