If you smell gas in a Lithonia home, leave the house and call 911 and Atlanta Gas Light at 877.427.4321 from away from the possible leak. Repairs past the meter, new appliance lines and pressure tests are plumber work, so call the number on this page to be connected with a local plumber in Lithonia.

Am I actually in the City of Lithonia?
Maybe not. The City of Lithonia is a small historic granite-quarrying town around Main Street, about 18 miles east of downtown Atlanta. The Lithonia mailing area is much larger and overlaps Stonecrest and unincorporated DeKalb County. That matters for gas work because of permits: the City of Lithonia's Building and Permitting Division at 6920 Main Street issues plumbing permits only inside city limits, through its Citizen Portal. Addresses outside go to the City of Stonecrest or DeKalb County instead.
Who owns the gas pipes in Lithonia?
The city has no gas department. Atlanta Gas Light is almost certainly the pipe utility, though AGL's lookup was not used to confirm it, and residents buy gas from certificated marketers. Check your bill to confirm. For a leak, leave first and call 911 and AGL at 877.427.4321.
What should I expect in an older Lithonia house?
Around Main Street and the Lithonia Historic District, older homes are common. For the much larger 30058 ZIP, city-data figures show about 16% of houses built before 1980, but the historic core is older than that average. In older houses, plumbers often find black iron gas pipe that has been tapped for new appliances over the decades, valves that no longer turn freely and brass connectors that should be replaced. Newer homes in the surrounding area typically have flexible stainless tubing that needs bonding to the electrical grounding. In either case, new work is pressure tested before gas is turned on.
A Lithonia note
When you call the number on this page, an independent plumber who works in east DeKalb will ask whether the address is inside city limits so the right office handles the permit. Keep any AGL tag or paperwork from a leak call; it tells the plumber what the utility found.
For a repair, the plumber locates the leak on the house side of the meter, replaces the bad fitting or section, and pressure tests the whole system. For a new appliance, they size a branch, add a shutoff at the appliance and arrange the inspection with whichever office covers your address.
