Gas Line Repair in Boulder, CO
63% of households in Boulder heat with utility gas, which means a buried service line runs from the street to a meter on most of these properties. Where that line ends is a federal definition, and it decides who repairs what.
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 Boulder, where 63% 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 Boulder 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: 54,241 occupied housing units. Read it as fuel rather than as plumbing. The share on utility gas is how many houses burn it, which is the nearest thing published to how many have a service line. Service line definition: 49 CFR § 192.3, via PHMSA interpretation PI-12-0003.
Across Colorado as a whole, 68% of households are on mains gas and 3% on tank propane. Boulder sits 5 points below the state on mains and 1 point above 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
Ask which side of the meter the work is on before anything else. On the utility side it may not be a contractor job at all, and a quote that has not established that has not established whose problem it is.

Checking a plumber in Colorado
Colorado licenses are issued by the Colorado State Plumbing Board, Division of Professions and Occupations, which publishes a public search you can use before work begins.
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. Non-emergency work in Boulder goes through this number as well.
