Ephraim, Utah has adopted: No separately adopted local building code was found for Ephraim City or Sanpete County; both apply Utah's statewide State Construction Code under Utah Code Title 15A. Per Utah Code § 15A-2-103 (version effective 7/1/2026, current as of 2026-07-19): 2024 International Building Code (including Appendices C and J), 2021 International Residential Code (including Appendix AQ), 2024 International Plumbing Code, 2024 International Mechanical Code, 2024 International Fuel Gas Code, 2023 National Electrical Code, 2024 International Energy Conservation Code, 2024 International Existing Building Code, the HUD Code and 2005 NFPA 225 for manufactured homes, and the residential provisions of the 2024 International Swimming Pool and Spa Code.; Utah Code § 15A-2-103(2) separately authorizes a local compliance agency to adopt the 2006 Utah Wildland Urban Interface (WUI) Code by local ordinance. Sanpete County's Building Department page links a WUI page and county WUI maps and requires an onsite inspection before a WUI plan is approved (per the county's Residential Building Plans Requirement Checklist), indicating the WUI code is applied in practice, but no formal county or city WUI-adoption ordinance was located to confirm the exact edition/amendments.; DISCREPANCY FLAGGED: Sanpete County's own 'Residential Building Plans Requirement Checklist' (sanpetecountyutah.gov/DocumentCenter/View/722/Building-Plans-Checklist) still labels its general construction plan section 'GENERAL CONSTRUCTION PLAN AS PER 2009 IRC' and cites '603 IMC 2012' for duct sizing — both several code cycles behind the current statewide-adopted 2021 IRC / 2024 IMC. This checklist document itself does not carry a visible revision date. Applicants should confirm the currently enforced code edition directly with the Building Official rather than relying on the checklist's code-year references.. Local amendments apply — see the Ephraim overview page for the full list.

Only if it is larger than 200 square feet. Smaller accessory buildings do not need a written permit but must still meet the City's setback, height, and coverage standards under Ephraim City Ordinance § 10-12-020-L.
