Codes adopted
2021 International Building Code (IBC), including Appendices C & J — Utah Code § 15A-2-103(1)(a). Iron County's own building.gov page and forms index do not publish a distinct county code-adoption page; per Utah's Title 15A compliance-agency model, unincorporated Iron County (like unincorporated Washington County in this corpus) is bound by the statewide-adopted specific editions absent its own published amendment.2021 International Residential Code (IRC), including Appendix Q — Utah Code § 15A-2-103(1)(b); this edition continues in force after the 7/1/2026 statutory rollover (only the IRC is held at 2021 while other codes advance to 2024).2021 International Plumbing Code (IPC) — Utah Code § 15A-2-103(1)(d) (2021 edition in force through 6/30/2026; 2024 IPC takes effect 7/1/2026 per the same statute).2021 International Mechanical Code (IMC) — Utah Code § 15A-2-103(1)(e) (2021 edition through 6/30/2026; 2024 IMC effective 7/1/2026).2021 International Fuel Gas Code (IFGC) — Utah Code § 15A-2-103(1)(f) (2021 edition through 6/30/2026; 2024 IFGC effective 7/1/2026).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Electrical Code (NEC) — Utah Code § 15A-2-103(1)(g); NEC remains 2023 across the 7/1/2026 statutory rollover (not superseded by a 2024/2026 NEC edition in that cycle).2021 International Energy Conservation Code (IECC) — Utah Code § 15A-2-103(1)(h) (2021 edition through 6/30/2026; 2024 IECC effective 7/1/2026).2021 International Existing Building Code (IEBC) — Utah Code § 15A-2-103(1)(i) (2021 edition through 6/30/2026; 2024 IEBC effective 7/1/2026).2021 International Swimming Pool and Spa Code (ISPSC), residential provisions — Utah Code § 15A-2-103(1)(n) (2021 edition through 6/30/2026; 2024 ISPSC effective 7/1/2026).NOTE: As of this file's lastVerified date (2026-07-03), the statutory rollover date of 7/1/2026 has passed; the 2024 editions of IBC, IPC, IMC, IFGC, IECC, IEBC, and ISPSC are the current statewide default per Utah Code § 15A-2-103 (version effective 7/1/2026), superseding the 2021 editions cited above wherever they overlap. IRC remains 2021 and NEC remains 2023. Iron County's own building.gov/building page and its Forms index (ironcountyut.gov/building/forms) do not independently republish specific code-edition numbers, so this file reports the statutory default rather than a county-specific citation — flagged here rather than silently assumed identical to Cedar City's page, which does publish its own distinct Current Adopted Codes list.
