3 rules for unincorporated Dorchester County, South Carolina.
Verified from official government sources
Unincorporated Dorchester County is generally permissive about occasional yard sales, but towns regulate them. Summerville treats frequent sales as a business under zoning, so repeat sales can trigger a license requirement.
There is no single countywide cap, but Summerville leans on state law: selling more than once a quarter can count as business activity, which residential zoning bars. That effectively limits frequent sales in town.
Yard sales are daytime events across Dorchester County and its towns, typically running roughly sunrise to dusk. Signs, tables, and unsold goods must be cleared promptly so the property does not read as blight.
