THE STATE-MANDATED 2021 IRC, CONFIRMED BY THE CITY'S OWN CURRENT DESIGN-CRITERIA SHEET. Utah Code 15A-2-103(1)(b) incorporates "the 2021 edition of the International Residential Code" by reference, and 15A-1-204(1)(a) provides that "the State Construction Code is the construction codes ... that the state and each political subdivision of the state shall follow" -- no local adoption ordinance is needed for the IRC to apply here. West Valley City's own Building Inspections Division publishes a "Design Criteria" sheet, effective April 18, 2026, that names the same edition and adds the rest of the adopted suite: "2021 International Residential Code (2021 IRC Chpt 11 - per State Amendments)," "2024 International Building Code," "2024 International Mechanical Code," "2024 International Fuel Gas Code," "2024 International Energy Conservation Code," "ASHRAE Standard 90.1-2016 (Energy)," "2023 National Electrical Code," "2009 ICC A117.1 Accessibility," and "2024 International Fire Code" and "2024 International Plumbing Code." The IBC and the trade codes carry a NEWER edition (2024) than the IRC (2021); the two are not the same edition and this record does not conflate them. Utah's Title 15A Chapter 4 Part 2 is the state's own codified, closed registry of every jurisdiction with a lawful local amendment to the IRC roof-assembly provisions, and it lists exactly two cities, Park City and Sandy City; West Valley City is not among them, so no lawful local IRC Chapter 8 or Chapter 9 variation exists here. Separately, Utah Code 65A-8-203(9)(a) (HB 48, 2025 General Session, effective 2026-01-01) requires a municipality to adopt and enforce the 2006 Urban Wildland Interface Code (UWUIC) in any area it has declared wildland-urban interface under that code's own Section 301; this record found no West Valley City ordinance or map declaring such a zone, and does not assert either way whether the UWUIC applies here. Dated change, read 2026-09-23 in the enrolled bill and in the codified Title 15A Chapter 2: H.B. 41 (2026 General Session, Laws of Utah 2026 Chapter 386) will take effect on January 1, 2027 for Utah Code 15A-2-103, whose Subsection (2) then reads "the Legislature adopts the 2024 edition of the International Wildland-Urban Interface Code, issued by the International Code Council" in place of the 2006 Utah Wildland Urban Interface Code "that may be adopted by a local compliance agency by local ordinance or other similar action as a local amendment". The same act enacts Section 15A-3-1101, which amends that code's Section 302.1 and deletes its Section 602. Section 65A-8-203(9)(c), in its current codified text, provides that where "the state adopts a different wildland urban interface building standard", a county or municipality "has two years from the date the state adopts the different wildland urban interface building standard to adopt the appropriate wildland urban interface building standard." This record does not decide how Subsection (9)(a), which still speaks of an edition of the Utah Wildland Urban Interface Code, reads against the 2027 text, or what the 2024 code requires of a reroof. Where the UWUIC does apply, its Section 507 pulls a roof covering replacement of 25 percent or more of the roof surface within a 12-month period into the same class of covering required for new construction.
