Plumbing Inspection in Lithonia, GA

Is my house in the City of Lithonia?

Maybe not. The City of Lithonia is a small historic granite-quarrying town centered on Main Street, but the Lithonia mailing area is much larger and overlaps Stonecrest and unincorporated DeKalb. That matters for permits. Inside city limits, the City of Lithonia's Building and Permitting Division at 6920 Main Street issues plumbing permits as their own trade permit type. Outside the city, permits go to the City of Stonecrest or DeKalb County instead.

Who handles the water and sewer?

DeKalb County Watershed Management, across the whole area. Its water comes from the Chattahoochee River and is treated at the Scott Candler plant. DeKalb is responsible from the main in the street through the meter, and the owner from the meter to the house's plumbing. DeKalb's service line inventory lets customers check their line's material, and its 2026 report advises extra flushing for homes with lead or galvanized service lines. Water main breaks go to DeKalb's 24-hour line at 770-270-6243.

How old are the homes?

Housing data for the small city isn't published separately. For ZIP 30058, which covers far more than the city, only about 16.3% of houses predate 1980. The older residential streets ringing Main Street are where a plumber is more likely to find galvanized supply pipe and aging drains, and where a sewer camera run makes the most sense.

Homes on DeKalb water with a separate irrigation system need a backflow assembly tested every year by a certified tester. Ask the seller for the last report. For any purchase, book the plumber early in the due-diligence period and share the general inspector's report so flagged items get attention first. Ask for written findings that separate urgent repairs from items to watch, so you have time to collect quotes and raise them with the seller. A camera run on the sewer line is worth adding on older lots or anywhere the drains have backed up before, and a meter test with every fixture off is a quick way to rule out a hidden leak on the line from the meter to the house.
