Stonecrest gets water and sewer from DeKalb County Watershed Management, whose backflow rules require commercial properties to carry a hazard-rated assembly tested every year. The City of Stonecrest's Building Department treats plumbing as subcontracted work by a state-license holder, with no inspections until the plumber's subcontractor affidavit is filed. Call the number on this page to be connected with a local plumber in Stonecrest.

Local conditions in Stonecrest
Stonecrest became a city in 2017 and is the largest city entirely within DeKalb County. It's built around The Mall at Stonecrest and I-20, with the Arabia Mountain heritage area to the south, and mail is often addressed 'Lithonia.' The city runs no water utility. DeKalb County Watershed Management treats Chattahoochee River water at its Scott Candler plant and handles both water and sewer; its 24-hour emergency repair line is 770-270-6243.
DeKalb's backflow section covers every customer. Commercial and multi-family properties need an assembly matched to their hazard level on the customer side of the meter, installed by a plumbing contractor holding a Georgia license and tested yearly by a GBPAT-certified tester. DeKalb is responsible for the service line through the meter, and the owner from there to the building.
Permits come from the City of Stonecrest Building Department on Stonecrest Boulevard, through the Citizenserve portal. Its building permit application lists plumbing as subcontracted work, and each subcontractor, who must hold a state license, has to file a Subcontractor Affidavit before inspections can happen. If a contractor hasn't filed one, the job will stall at inspection.
The ZIP 30038 housing figures show about 23% of homes built before 1980, so most of the commercial stock around the mall is newer, though older buildings exist along the corridors.
What affects the cost
- Whether the space is a standalone building or part of a larger center with shared lines

- After-hours work around retail hours
- City permit and affidavit steps

What happens when you call
You'll be connected with an independent local plumber who takes commercial jobs in Stonecrest. Mention the type of business and whether the landlord or management company controls the building's plumbing. Retail tenants in larger centers often can't shut water off to their own space without the property manager, so have that contact ready, along with your store hours and any past backflow test reports.
