Codes adopted
2021 International Residential Code (IRC) for architectural design — per Wasatch County's own 'Plan Submission Requirements - Single Family Dwelling' checklist (wasatchcounty.gov/DocumentCenter/View/1032/Checklist-Single-Family-Dwelling), which states construction plans and drawings 'must be designed to and reflect the 2021 International Residential Code for architectural.'2021 International Building Code (IBC) for structural design — per the same county checklist, which states plans 'must be designed to and reflect... 2021 International Building Code for structural,' and that structural engineering calculations 'must be designed to and reflect the 2021 International Building Code and stamped and signed by the engineer of record.'Utah Energy Conservation Code — referenced directly on the same county checklist ('If using the Utah Energy Conservation Code, the ResCheck must have a passing score of 5% or better'); the statewide-adopted edition is the 2021 International Energy Conservation Code (IECC) per Utah Code Sec 15A-2-103, which Wasatch County's own building checklist does not separately re-cite by ICC edition number.Utah Wildland Urban Interface Code, adopted under Utah Code Sec 15A-2-103 — referenced directly on the same county checklist for site-plan defensible-space requirements ('defensible space provisions and elevations, if required by the Utah Wildland Urban Interface Code adopted under Section 15A-2-103').2021 International Plumbing Code (IPC), 2021 International Mechanical Code (IMC), 2021 International Fuel Gas Code (IFGC), 2023 National Electrical Code (NEC), 2021 International Existing Building Code (IEBC), and 2021 International Swimming Pool and Spa Code (ISPSC) residential provisions — Wasatch County's own Building Department pages and Forms & Checklists index (wasatchcounty.gov/380) do not republish a distinct county code-adoption list beyond the IBC/IRC citation on the Single Family Dwelling checklist; per Utah's Title 15A compliance-agency model (Utah Code Sec 15A-1-202, Sec 15A-2-103), unincorporated Wasatch County is bound by these statewide-adopted specific editions absent its own published amendment, consistent with the same statutory-default pattern documented for unincorporated Iron and Tooele Counties in this corpus.NOTE: As of this file's lastVerified date (2026-07-03), the statutory rollover date of 7/1/2026 (Utah Code Sec 15A-2-103) has passed; the 2024 editions of IBC, IPC, IMC, IFGC, IECC, IEBC, and ISPSC are the current statewide default, superseding the 2021 editions wherever they overlap. IRC remains 2021 and NEC remains 2023 across that rollover. Wasatch County's own 'Plan Submission Requirements - Single Family Dwelling' checklist (fetched 2026-07-04) still explicitly names '2021 International Residential Code' and '2021 International Building Code' without a superseding revision date visible on the document itself — reported verbatim as the county's own published text, flagged here rather than silently reconciled to the post-rollover statutory default.
