Full Breakdown

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.

Violations & Penalties

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.

Frequently Asked Questions

Can a city allow taller buildings than the IBC permits?

No. The IBC structural height-area limits are the maximum, not the minimum. Cities may impose stricter zoning height limits but cannot waive code requirements.

Are there special rules for hurricane-prone areas?

Yes. Coastal counties follow IBC wind-load provisions referencing ASCE 7 wind maps, with stricter design requirements in high-wind zones along the coast.

Does this apply to single-family homes?

Single-family homes follow the IRC, which has its own height limitations typically capping wood-frame construction at three stories above grade.
