Charleston-specific permitting context
Charleston contractors register through the Customer Self Service portal to apply for permits and schedule inspections, and work in the historic district requires Board of Architectural Review approval before permits issue. Flood-zone elevation, hurricane wind ratings, and tidal-flooding rules add layers most inland markets never see.
Climate factors: A humid subtropical coastal climate with hot humid summers, a June-to-November hurricane season, and salt air plus tidal flooding that demand elevation, corrosion resistance, and wind-rated construction.
