South Carolina permits
Do you need a permit in South Carolina?
South Carolina enforces the SC Building Codes (IRC-based) with local enforcement, and stricter coastal provisions in the eight coastal counties. SC requires a residential builder or specialty contractor license through LLR for projects over $5,000. Electrical and plumbing are licensed. Charleston adds historic-district review on the peninsula.

Can a homeowner pull the permit?
Yes, in most cases. Owner-occupied primary residences. Homeowner self-perform exempt from LLR licensing; hired covered work needs a licensed builder.
Where to file: County or municipal building department. Charleston, Columbia, Greenville, Myrtle Beach have portals. Coastal projects get windstorm review. Plan review 1-3 weeks.
