NORTH CHARLESTON, S.C. — One of the nation’s most popular retailers appears poised to expand its Lowcountry footprint.
According to documents submitted to the South Carolina Department of Environmental Services, Costco Wholesale is planning a new warehouse in North Charleston near Interstate 26 and Blue House Road. The proposed development would include a 181,000-square-foot membership warehouse and a fuel station with more than 30 gas pumps, making it one of the largest retail projects currently proposed for the area.
If approved and constructed, the new location would become South Carolina’s eighth Costco warehouse and the second in the Charleston region, joining the existing West Ashley store. The expansion reflects the continued population and economic growth across Berkeley, Charleston, and Dorchester counties, where demand for retail services continues to increase.
The proposed site along the I-26 corridor would provide convenient access for residents in North Charleston, Goose Creek, Summerville, Hanahan, Moncks Corner, and surrounding communities. It would also place Costco closer to one of the fastest-growing commercial corridors in the state.
Costco’s arrival would introduce another major competitor into the Lowcountry retail market, joining existing warehouse clubs while complementing nearby shopping destinations such as Tanger Outlets. Beyond shopping, the project is expected to generate construction activity and create new permanent jobs once the store opens.
At this stage, the project remains in the planning and permitting process. While site plans have been submitted to state regulators, no official construction schedule or opening date has been announced. Additional local approvals will likely be required before work can begin.
For many Lowcountry residents, the news is likely to be welcomed. Costco has built a loyal following for its bulk groceries, household goods, pharmacy, optical services, fuel stations, and rotating selection of seasonal merchandise. The new North Charleston location would offer shoppers another convenient option while helping accommodate the region’s continued growth.
As permitting moves forward, more details—including timelines and construction milestones—are expected to emerge in the coming months.
