Iron County's own building.gov page and forms index publish no distinct county code-adoption page; under Utah's Title 15A compliance-agency model, unincorporated Iron County is bound by the statewide-adopted editions absent its own published amendment.; 2021 International Residential Code (IRC), including Appendix Q — Utah Code § 15A-2-103(1)(b); unchanged by the July 1, 2026 revision — only the IRC (and NEC) held at their prior editions while the other codes advanced to 2024 — still the current edition.; 2024 International Plumbing Code (IPC) — Utah Code § 15A-2-103(1)(d); current edition as of July 1, 2026 (2021 edition governed through June 30, 2026).; 2024 International Mechanical Code (IMC) — Utah Code § 15A-2-103(1)(e); current edition as of July 1, 2026 (2021 edition governed through June 30, 2026).; 2024 International Fuel Gas Code (IFGC) — Utah Code § 15A-2-103(1)(f); current edition as of July 1, 2026 (2021 edition governed through June 30, 2026).; 2023 National Electrical Code (NEC) — Utah Code § 15A-2-103(1)(g); NEC remains 2023 across the 7/1/2026 statutory rollover (not superseded by a 2024/2026 NEC edition in that cycle) — still the current edition.; 2024 International Energy Conservation Code (IECC) — Utah Code § 15A-2-103(1)(h); current edition as of July 1, 2026 (2021 edition governed through June 30, 2026); statute has no residential/commercial split — one edition applies to both.; 2024 International Existing Building Code (IEBC) — Utah Code § 15A-2-103(1)(i); current edition as of July 1, 2026 (2021 edition governed through June 30, 2026).; 2024 International Swimming Pool and Spa Code (ISPSC), residential provisions — Utah Code § 15A-2-103(1)(n); current edition as of July 1, 2026 (2021 edition governed through June 30, 2026).; Utah Code § 15A-2-103, in the version headed 'Effective 7/1/2026 / Superseded 1/1/2027', put the 2024 editions of the IBC, IPC, IMC, IFGC, IECC, IEBC and ISPSC listed above into effect on July 1, 2026, replacing the 2021 editions; the IRC (2021) and NEC (2023) did not change. The 1/1/2027 version of the statute carries identical editions, so no further flip is expected then. Iron County's own building.gov/building page and its Forms index (ironcountyut.gov/building/forms) do not republish specific code-edition numbers, so the editions here are the statutory default rather than a county-specific citation — Cedar City, by contrast, does publish its own distinct Current Adopted Codes list.. Local amendments apply — see the Unincorporated Iron County overview page for the full list.
