Gas Line Repair in Greenbrae, CA
Greenbrae is a mains gas town — 71% of households heat with utility gas. The useful thing to know before anything goes wrong is where the utility’s responsibility stops.
Read this first
A buried service line and a meter sit on most properties in Greenbrae, where 71% 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 Greenbrae is supplied
On a mains connection there are two systems, not one, and the meter divides them. The federal definition puts the end of the regulated service line at the meter outlet; local code governs everything beyond it.
Practically, that means part of the problem may not be yours at all — and part of it certainly is.
| Households in Greenbrae | Share |
|---|---|
| Utility (mains) gas | 71% |
| Bottled or tank propane | 2% |
| Electricity | 23% |
| Fuel oil and kerosene | 0% |
| Wood and everything else | 4% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 5,651 occupied housing units. The table counts heating fuel rather than pipework. A house on mains gas almost certainly has a service line; the Census does not say so directly and neither do we. 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. Greenbrae sits 6 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
PHMSA describes excavation damage as the leading cause of pipeline incidents, and puts the effect of one free phone call plainly: someone who calls 8-1-1 before they dig has a 99 percent chance of avoiding an incident, injury, harm to the environment and even death.

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. Other Greenbrae requests are covered by the same line.
