Key Zoning Facts
Hilton Head Island is a town of approximately 40,000 residents in Beaufort County, South Carolina. As a premier resort and residential community, the town manages land use through a zoning ordinance that balances environmental preservation, resort development, and residential quality of life.
Hilton Head Island's zoning framework uses a density-based residential system with RM-4 (4 units/acre), RM-8 (8 units/acre), and RM-12 (12 units/acre) districts, along with a Suburban district (S, 20,000 sq ft minimum lots), Light Commercial (LC), and Resort Commercial (RC) districts.
Key Zoning Districts
The Suburban (S) district requires minimum 20,000 sq ft lots with 25-foot front setbacks, 10-foot side setbacks, and 20-foot rear setbacks. The residential medium districts (RM-4, RM-8, RM-12) regulate density by units per acre rather than strict lot size minimums. The RM-4 and RM-8 districts have a 35-foot height limit, while RM-12 allows up to 45 feet. The Light Commercial and Resort Commercial districts serve the island's retail and tourism-oriented businesses.
ADU Regulations
ADU (Accessory Dwelling Unit) regulations have not been confirmed for Hilton Head Island. South Carolina does not have a statewide ADU mandate, so ADU policies are determined at the local level. Contact the Planning Department to verify whether ADUs are currently permitted and what requirements may apply.
Development Process
Development on Hilton Head Island 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
- Design Review -- Projects may require review for compliance with the town's design standards
- 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 on Hilton Head Island, property owners should:
- Verify the zoning classification of their property
- Review setback, height, and lot coverage requirements
- Check for any overlay districts or environmental protection regulations
- Determine if the property is in a flood zone using FEMA's flood map service
- Confirm whether HOA covenants or deed restrictions apply (very common on the island)
- Contact the planning department at (843) 341-4757 for pre-application guidance
