Gas Line Repair in Annapolis, MD
Annapolis runs on both: 33% mains gas, 2% tank propane, 36% on gas of some kind. The two arrangements answer the ownership question completely differently.
Read this first
In Annapolis, 33% of homes are on mains gas and 2% on bottled, so the town average settles nothing about any one address. Mains gas ends the utility's regulated line at the meter outlet; a tank supply has no such boundary.
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 Annapolis is supplied
Two arrangements in one town, and the difference is not cosmetic. A mains connection has a meter, and 49 CFR § 192.3 ends the regulated service line at its outlet. A propane installation has no meter boundary and belongs to the property owner end to end.
Establish which you have before anything else on this page applies.

It does not enumerate service lines, and no table does at this geography; what it gives is the best available indication of which arrangement a property is on. Service line definition: 49 CFR § 192.3, via PHMSA interpretation PI-12-0003.
Across Maryland as a whole, 45% of households are on mains gas and 3% on tank propane. Annapolis sits 12 points below 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
Excavation damage remains the leading cause of pipeline incidents according to PHMSA. That is not a fact about pipelines so much as a fact about gardening, and the prevention is one free call to 8-1-1 before the first spade goes in.

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 Maryland
Maryland licenses are issued by the Maryland State Board of Plumbing, Department of Labor, 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. Gas is one part of what Annapolis calls us about.
