Summary
Operating as a general contractor in Charleston, South Carolina requires obtaining the appropriate Residential Builders License through the state Department of Labor, Licensing and Regulation, which involves passing an exam, demonstrating experience, and meeting financial requirements. Contractors must secure building permits for most projects through the Charleston Building Department, maintain proper insurance coverage including general liability and workers' compensation, and ensure all work complies with local building codes and historic preservation requirements where applicable. Charleston's unique historic districts add additional compliance considerations, as many areas require special approvals for exterior modifications. The city has streamlined its permitting process with online applications, but contractors should allow adequate time for plan review and inspections. Success in Charleston's market requires understanding both standard construction regulations and the special requirements that come with working in one of America's most historic cities.
