Key Zoning Facts
Summerville Zoning Overview
Summerville is a town of approximately 53,643 residents in Dorchester County, South Carolina. Known as the "Flower Town in the Pines," Summerville manages land use through a comprehensive zoning ordinance administered by the town's planning department.
Summerville's zoning framework includes large-lot single-family zones (RS-1, 12,000 sq ft minimum), standard single-family zones (RS-2, 8,000 sq ft minimum), multi-family residential (RM), neighborhood commercial (C-1), general commercial (C-2), and industrial (I) districts.
Key Zoning Districts
The RS-1 district requires 12,000 sq ft minimum lots with 25-foot front setbacks, 8-foot side setbacks, and 20-foot rear setbacks. The RS-2 district allows 8,000 sq ft lots with 20-foot front, 5-foot side, and 15-foot rear setbacks. Both single-family districts have a 35-foot height limit.
The RM district permits multi-family housing including apartments and townhomes, with dimensional standards that vary based on the specific development.
ADU Regulations

Property owners interested in building an accessory dwelling unit should contact the Planning Department at (843) 871-6000 for current rules.
Development Process
Development in Summerville generally requires obtaining the appropriate permits from the town's planning and building departments. The process typically involves:
- Zoning Verification -- Confirm that your proposed use is permitted in the applicable zoning district
- Site Plan Review -- For commercial and multi-family projects, submit a site plan for review
- Building Permit -- Apply for a building permit with construction documents

For projects that do not conform to existing zoning, property owners may need to seek a variance, special exception, or rezoning through the local board of zoning appeals or planning commission.
