While zoning height limits remain local, structural height and construction-type rules in South Carolina are governed by the statewide-adopted International Building Code under SC Code Title 6, Chapter 9, applying uniformly to all jurisdictions.
SC Code Section 6-9-50 mandates statewide adoption of the IBC and IRC. The IBC limits building heights based on construction type, occupancy, and fire-resistance ratings (Chapter 5 height and area limitations). For example, Type V-B wood-frame construction is limited to specific story counts depending on use. Local zoning ordinances may impose lower height caps but cannot exceed IBC structural maxima. Coastal jurisdictions also follow Chapter 16 wind-load provisions tied to ASCE 7 maps. The Building Codes Council reviews local amendments for consistency with state minimums.
Exceeding code height-area limits results in plan-review denial, stop-work orders, and civil penalties enforced by local building officials operating under state delegation.
