| IEBC — International Existing Building Code | NO STATEWIDE EDITION — SOUTH CAROLINA ADOPTS NO IEBC EDITION AT STATE LEVEL. This is a negative finding, not a missing value, and it must never be rendered as an edition badge. S.C. Code Ann. § 6-9-60 places the existing building code in the PERMISSIVE tier: a municipality or county MAY adopt it by local ordinance, and until it does, no IEBC applies in that jurisdiction. Where a local government does adopt, the statute confines it to "only the latest editions", so the operative edition is whatever ICC edition is current at the time of that local ordinance and is NOT fixed by the state. Contrast the eight mandatory code types (IBC, IRC, IFC, IPC, IMC, IFGC, NEC, IECC), whose editions the Building Codes Council fixes statewide under § 6-9-50. | S.C.

Contrasted with S.C. Code Ann. § 6-9-50(A), read first-hand at the same time, whose mandatory list of seven ICC codes plus the NFPA National Electrical Code DOES NOT INCLUDE the existing building code. § 6-9-60 history: 1962 Code Section 14-400.586, amended through 2003 Act No. 83, § 1, eff. 2003-07-02.

| IECC — International Energy Conservation Code | 2009 IECC — CORRECT AND RE-VERIFIED 2026-09-14. Fixed by STATUTE (S.C. Code Ann. § 6-10-30), not by the Building Codes Council, and therefore NOT on the 2021 or 2024 ICC cycle its sibling codes follow. NOT 2021. NOT 2024.

Building Codes Council's own "Building Codes in Effect for South Carolina" (rev. 12/2022) confirms the mechanism verbatim: legislative adoption "thus removing it from the normal adoption process" and "Future updated versions must also be adopted by statutory amendment." Adopted 2012-04-02 by Act 143 (H4639); implementation 2013-01-01. NOT adopted under § 6-9-40/§ 6-9-50, which govern every other South Carolina code type. · source ↗ |

CORRECT AND IN FORCE AS OF 2026-09-27. NOT the 2024 IPC YET: the Building Codes Council HAS adopted the 2024 cycle, but with an implementation date of 2027-01-01, so the 2021 edition remains the operative one until 2026-12-31. (CORRECTION 2026-09-27, run 1785: this field previously asserted that as of 2026-09-08 the Council had "only a Notice of Intent ... posted, no adoption vote and no implementation date". THAT WAS FALSE AND WAS ALREADY FALSE WHEN WRITTEN — the Council's own 2024 Building Code Modification Index, Version 1.0 dated 2025-11-03, enumerates the adopted 2024 modifications and states the implementation date.
