Costco to open Stone Mountain store in Atlanta metro expansion

Costco’s next Atlanta-area warehouse is taking shape on 31.1 acres at 1915 West Park Place Blvd. in Stone Mountain, where crews are turning the former Stone Mountain Tennis Center into Mountain Marketplace. The August 2026 opening adds another anchor to Costco’s Georgia footprint and gives the region’s warehouse workforce another hiring, transfer and staffing point as metro Atlanta keeps expanding.

Fuqua Development is leading the project just off U.S. Highway 78 and says Mountain Marketplace will be a Costco-anchored mixed-use development with Chick-fil-A, Whataburger, a bank and a community park. One report put the total investment at about $200 million. Fuqua has also said nearly 45,000 residents live within three miles of the property, a dense customer base for a site that once served the 1996 Atlanta Olympics and then sat long after the games were over.

The site’s shift from sports venue to retail corridor has been years in the making. Gwinnett County commissioners approved the sale of the former tennis center land in March 2024, voting unanimously to move the property to Fuqua Acquisitions. At the time, county leaders framed the deal as a chance to spur reinvestment in the historically underserved Park Place area near Stone Mountain, while the development plan called for a Costco, four restaurants and 248 apartments, including affordable housing.

That mix matters beyond the real estate. A warehouse opening inside a larger retail-and-housing project changes how work gets distributed in a market that already has a heavy Costco presence. Georgia’s warehouse directory lists 17 Costco locations in the state, so Stone Mountain will not be entering a thin market or a new part of the country. It will be another node in an established metro Atlanta network where managers will need to staff departments, move employees where they are needed and absorb another wave of local demand.

For Costco workers across the region, the new store signals more than another opening on the calendar. It adds another place where front-end, stock, forklift, meat, bakery, optical and management jobs will have to be filled and trained, while existing warehouses around Atlanta adjust to a larger footprint in one of the company’s busiest Southern markets. The Stone Mountain project turns an abandoned Olympic site into a working warehouse district, and that changes the labor map as much as the landscape.
