At-a-glance
- Licensing body: South Carolina Contractor's Licensing Board
- License threshold: Residential builder license required for projects over $5,000; specialty license under that
- Permit authority: County or city building department
- Typical fees: $100–$400 for a window replacement permit
License threshold: $5,000
The South Carolina residential builder license threshold is lower than most states - $5,000. Any whole-home window project crosses this line, so a state-licensed builder is required.
Coastal & moisture considerations
Charleston, Myrtle Beach, and Hilton Head homes sit in windborne-debris zones, so impact-rated glass or approved shutters are typically required, and salt air favors vinyl or fiberglass frames over bare aluminum.
