Key Zoning Facts
Hanahan is a city of approximately 25,681 residents in Berkeley County, South Carolina. The city manages land use and development through its local zoning ordinance, which divides the municipality into residential, commercial, and industrial districts with specific development standards for each.
Hanahan's zoning framework includes standard single-family zones (R-1, 10,000 sq ft minimum), compact single-family zones (R-2, 7,500 sq ft minimum), a commercial district (C-1), and an industrial zone (I).
Key Zoning Districts
The R-1 district requires minimum 10,000 sq ft lots with 25-foot front setbacks, 8-foot side setbacks, and 20-foot rear setbacks. The R-2 district allows 7,500 sq ft lots with 20-foot front, 5-foot side, and 15-foot rear setbacks. Both districts have a 35-foot maximum building height.
ADU Regulations
ADU (Accessory Dwelling Unit) regulations have not been confirmed for Hanahan. South Carolina does not have a statewide ADU mandate, so ADU policies are determined at the local level. Contact the Hanahan Planning Department to verify whether ADUs are currently permitted and what requirements may apply.
Development Process
Development in Hanahan generally requires obtaining the appropriate permits from the city'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
- Inspections -- Schedule required inspections during construction
- Certificate of Occupancy -- Obtain final approval before occupying the structure
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.
Key Considerations
Before starting any development project in Hanahan, property owners should:
- Verify the zoning classification of their property

- Check for any overlay districts or special regulations
- Determine if the property is in a flood zone using FEMA's flood map service
