The City of Stone Mountain is a small historic village whose water and sewer belong to DeKalb County, while its own Building Permits Department handles plumbing permits for addresses inside the city. Plumber Atlanta puts callers in touch with independent plumbers at no cost and does not do the work itself. Call the number on this page to be connected with a local plumber in Stone Mountain.

The city and the mailing address are not the same
The City of Stone Mountain is a village of 6,703 people at the western foot of the mountain, with a preserved Main Street dating from around 1900. But the Stone Mountain ZIPs, 30083, 30087 and 30088, cover large unincorporated suburbs well beyond the city; 30083 alone has more than 62,000 residents. The city's permit office covers only addresses inside the city limits, so for an unincorporated Stone Mountain address, ask DeKalb County about permits.
A village with deep roots
Founded around 1839 as New Gibraltar and renamed Stone Mountain in 1847, the city lies in DeKalb County about 13 miles east of downtown Atlanta. Stone Mountain Park sits next door, and East Ponce de Leon Avenue and the PATH trail connect it to the rest of the county.
Housing from the 1960s to the 1980s
About two-thirds of homes in the city were built between 1960 and 1989, and just over half predate 1980, for a median year of 1979. Plumbing that old commonly includes galvanized or early copper supply lines, cast iron drains, and sewer laterals that have settled or let in roots. A plumber may want to check pressure at the main, look at the water heater's age and venting, or run a camera down a lateral that keeps backing up.
DeKalb County handles water and sewer
City Public Works does not touch water or sewer; those calls go to DeKalb County Watershed Management at (770) 270-6243 for emergencies, or 770-621-7200 for general questions. DeKalb treats Chattahoochee River water at its Scott Candler plant and publishes a yearly water quality report. DeKalb owns the service line from the main through the meter, and the property owner is responsible from the meter to the house. Multi-family and commercial buildings fall under DeKalb's backflow program, with an annual test by a certified tester.
Permits inside the city
The City of Stone Mountain requires separate trade permits and offers a Plumbing Permit Application. Permits are processed by Permit Service Group for the city, inspections are done by SAFEbuilt, and the city asks residents to contact City Hall at 875 Main Street ((770) 498-8984) before starting any construction.
Gas
Gas in Georgia is deregulated, and the city's utilities page points to the Public Service Commission for choosing a marketer. Atlanta Gas Light is the expected pipe utility. If you smell gas, leave first, then call 911 and AGL at 877.427.4321.
