Beaufort County manages building permits for all unincorporated areas, while incorporated municipalities like Beaufort, Bluffton, Hilton Head Island, and Port Royal maintain their own independent building and planning departments. The county enforces strict coastal and environmental overlays, including the Special Protection Areas and critical area requirements managed by the South Carolina Department of Environmental Services (SCDES).
The county enforces a rigorous Community Development Code that includes specific tree protection ordinances and strict architectural standards for development within the Rural and Critical Lands Preservation areas.
How this fits with the state
The state authority here is South Carolina Contractor's Licensing Board; Residential Builders Commission. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
