Washington City Building Department's own 'Climatic and Geographic Design Criteria' notice was live-checked 2026-07-16 (raw HTML, not an AI summary) and STILL displays '2021 IBC' — the city page has NOT been updated to reflect the statewide 7/1/2026 transition; 2021 Utah State Residential Code (based on IRC) — REMAINS CURRENT; Utah Code § 15A-2-103(1)(b) did not change this edition in the 7/1/2026 amendment.

The Washington City Building Department page states it directly: “MAY 7 2025 UPDATE OF ADOPTED CODES BY THE STATE OF UTAH: 2023 NEC code update,” superseding the 2020 NEC still shown struck through on that page. Most Washington County-area jurisdiction pages leave the electrical edition to be inferred from state law; this one states it on the page itself.; 2024 International Energy Conservation Code (IECC), single unsplit statewide edition — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(h). Washington City's own page was live-checked 2026-07-16 and STILL displays '2021 IECC' — the city page has NOT been updated; Residential provisions of the 2024 International Swimming Pool and Spa Code (ISPSC) — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(n).

Washington City's own Building Department page (its 'Climatic and Geographic Design Criteria' notice) still displays 2021 editions for the IBC, IMC, IPC, IFGC, IECC and ISPSC — it has not been updated to reflect the statutory transition, unlike its NEC line, which was updated in May 2025. The governing codes are the statutory editions (2024/2021/2023 by subsection) under Utah's statewide-mandatory code regime (Utah Code § 15A-1-204); the City's own page text is preserved above as local-document context.
