If a Vienna home smells of gas, leave first, then call 911 and Washington Gas at 844-WASHGAS (844-927-4427), option 1, from outside. Gas piping work past the meter is permitted by Fairfax County, and in-town projects also need Town of Vienna approval. Call the number on this page to be connected with a local plumber in Vienna.

Who handles gas permits for a Vienna home?
Two offices, if you live inside town limits. Fairfax County Land Development Services issues the plumbing, gas and household appliance permits through PLUS, and projects in the Town of Vienna also need separate approval from the Town, which is uploaded to the County's PLUS record. The Vienna postal area (ZIPs 22180 through 22182) reaches well beyond the town, and homes outside its limits deal only with the County.
The County's rules are the same either way. A gas water heater or furnace replaced like-for-like uses a Household Appliance (HAPL) permit. New gas piping takes a Residential Plumbing permit. LDS answers questions at 703-222-0801.
Which gas utility serves Vienna?
Fairfax County says most residents are on Washington Gas, with Columbia Gas of Virginia covering some areas such as parts of Chantilly and Herndon. Vienna homes with gas are generally on Washington Gas. Not every house has a gas meter, though, so confirm service at your address before planning a gas appliance.
What should owners of older Vienna homes expect?
Vienna is an established town with largely older single-family neighborhoods; the median home in town was built in 1971. Gas piping in houses of that age is often original steel that has been extended for ranges, dryers and fireplaces over several remodels. Typical findings include valves that no longer turn freely, rust on pipe in damp basements or crawlspaces, abandoned branches left from removed appliances, and connectors older than the appliances they feed. When a house like this is expanded, a large addition often means the gas supply needs a fresh look, sometimes a larger line from the meter.
A Vienna note: when you call, say whether the house is inside town limits. It changes the paperwork, and a plumber who knows the Town approval step will build it into the schedule rather than discovering it at inspection. Also mention what fuels the house uses now. Switching an oil-fired furnace to gas, or adding gas to a home that has never had it, starts with Washington Gas confirming a main on the street and setting a meter, and only then does the inside piping get planned and sized.
