The City of Lithonia is a small historic town, but the Lithonia mailing area is far larger and overlaps Stonecrest and unincorporated DeKalb, so which office issues your plumbing permit depends on where you live; DeKalb County supplies water and sewer throughout. Plumber Atlanta is a free connection to independent plumbers rather than a plumbing company. Call the number on this page to be connected with a local plumber in Lithonia.

Plumbing services in Lithonia
City of Lithonia or just a Lithonia address?
The City of Lithonia had 2,662 residents in 2020. ZIP 30058 alone has more than 62,000. Most people with a Lithonia mailing address live in the City of Stonecrest or in unincorporated DeKalb County, not in the city itself. For plumbing, that difference decides who issues the permit:
- Inside the City of Lithonia: the city's Building and Permitting Division, 6920 Main Street (770-482-8136, weekdays 8 to 4, closed noon to 1).
- Elsewhere with a Lithonia address: the City of Stonecrest or DeKalb County, depending on location.
The City of Lithonia treats plumbing as its own trade permit type alongside building, electrical and mechanical permits, with applications through its online Citizen Portal.
The City of Granite
Lithonia grew up around granite quarrying, and its Main Street commercial core is ringed by older residential streets. The Lithonia Historic District includes the Lithonia Women's Club, a 1916 Masonic Lodge and The Seminary. The city is a gateway to the Arabia Mountain National Heritage Area, where some former quarries are now parkland. It lies along Interstate 20 at Exits 74 and 75, about 16 miles east of downtown Atlanta.
DeKalb water and sewer everywhere
Whichever jurisdiction you are in, DeKalb County Watershed Management supplies the water, drawn from the Chattahoochee River upstream of Atlanta and treated at the Scott Candler plant, and runs the sewer system. Main breaks go to DeKalb's 24-hour emergency repair line, 770-270-6243; billing and water cutoff is 404-378-4475.
DeKalb owns the line from the street main through the meter; the owner is responsible from the meter to the house. DeKalb's service line inventory lets you check what your line is made of, and its water quality report advises extra flushing for homes with lead or galvanized service lines. Single-family homes with irrigation need a backflow assembly tested every year.
Housing
Across ZIP 30058, about 16% of houses were built before 1980, so most of the area is newer subdivision housing. Inside the old city, around Main Street, older homes are more common, and with them older supply and drain piping.
Gas and calling
The city has no gas department; Atlanta Gas Light is the pipe utility. If you smell gas, leave the house before calling 911 and AGL at 877.427.4321. For plumbing, call this page's number and say whether you are inside the City of Lithonia. You will be connected with an independent plumber who works in the Lithonia area, and you agree on cost and timing with them.
