Required

THE 2021 INTERNATIONAL RESIDENTIAL CODE (WITH THE 2024 INTERNATIONAL BUILDING CODE), MANDATORY STATEWIDE UNDER UTAH LAW -- NOT A LOCAL WEST JORDAN ADOPTION, AND CONFIRMED BY THE CITY'S OWN CURRENT STATEMENT. Utah Code 15A-2-103(1): "the following construction codes are incorporated by reference ... (a) the 2024 edition of the International Building Code ... (b) the 2021 edition of the International Residential Code." Utah Code 15A-1-204(1)(a): "The State Construction Code is the construction codes ... that the state and each political subdivision of the state shall follow." 15A-1-204(1)(b)(ii)(A) reaches an existing building whose owner is "voluntarily engaged in ... the repair, renovation, remodeling, alteration, enlargement, rehabilitation, conservation, or reconstruction of the building." West Jordan's own Building & Safety Division Design Criteria page (last revised 07/2026) independently states: "BUILDING CODES: The Building Division enforces the following building codes with State of Utah amendments. 2024 International Building Code (including Appendices C & J), 2021 International Residential Code (including Appendix AQ) ... City of West Jordan - Title 10 Building Regulations." The City's own local Title 10 layered on top of the state code was not independently reachable this session: its code host, codelibrary.amlegal.com, returned an access-denied response rather than content. The only codified local IRC Chapter 9 amendments the Legislature has authorized anywhere in Utah (Title 15A, Chapter 4, Part 2) apply to Park City and Sandy City only, both wildfire wood-roof or ignition-resistant construction provisions, and neither names West Jordan. Separately, Utah Code 65A-8-203(9)(a) (enacted by HB 48, effective 2026-01-01) requires every municipality to "adopt and enforce" the 2006 Utah Wildland Urban Interface Code (adopted at 15A-2-103(2)) in any area it designates as wildland-urban interface; nothing self-executes and no statewide registry of adopting jurisdictions exists, so this record does not establish whether West Jordan has declared a UWUIC zone under Section 301. The City's own newsroom article (January 21, 2025) states publicly: "Is West Jordan vulnerable to a wildfire disaster? Thankfully, we sit well insulated from the wildland-urban interface." That is disclosed as the City's own public statement about its wildfire exposure, not as a Section 301 zone finding either way.

Required — Utah's statewide amendment packet to the 2021 IRC (Title 15A, Chapter 3, Part 2, all six sections, 48,780 characters swept) contains zero occurrences of "drip edge" and does not touch IRC Chapter 9's drip-edge provision (Section R905.2.8), so the base 2021 IRC requirement stands unmodified statewide; West Jordan has adopted no local amendment to Chapter 9 (the only two the Legislature has authorized anywhere in Utah apply to Park City and Sandy City). This record points at the section rather than quoting its operative text, which has not been opened by this project. About drip edge

Required — West Jordan's own Building & Safety Division Design Criteria page (last revised 07/2026) lists, among its published plan-review criteria: "ICE SHIELD UNDERLAYMENT: Yes." The same page states an "AIR FREEZING INDEX: <= 1000" and a "WINTER DESIGN TEMP: 8 F," both City-published figures a roofer would need alongside the underlayment requirement. About ice & water barrier

Not required — Counted across the full statewide 2021 IRC amendment packet (48,780 characters) and the enrolled 2026 amending act (H.B. 65, 253,370 characters): "UL 2218" 0, "Class 4" 0, "Class IV" 0, "hail" 0; the act's four "impact" hits are all attack-resistant glazing standards (ASTM F3561), not roof coverings. The only codified local IRC Chapter 9 amendments authorized anywhere in Utah (Park City and Sandy City) are both wildfire wood-roof provisions and name no impact-rating standard. Separately, Utah's 2006 Wildland Urban Interface Code, which every municipality must now adopt and enforce in any area it designates wildland-urban interface (Utah Code 65A-8-203(9)(a)), is fire-only: counted across its full 118,402 characters, "UL 2218," "FM 4473," "Class 4," "Class IV" and "hail" are each zero. No statewide registry of adopting jurisdictions exists, so this record does not establish whether West Jordan has designated a WUI zone; the City's own newsroom (January 21, 2025) states publicly that it sits "well insulated from the wildland-urban interface," disclosed as the City's own description of its wildfire exposure rather than a formal zone finding. Either way, a wildfire code implies nothing about hail impact resistance.

RESIDENTIAL WIND SPEED 105 MPH (3-SECOND GUST, 33 FEET ABOVE GROUND); EXPOSURE ASSUMED "C" UNLESS JUSTIFIED; SEISMIC DESIGN CATEGORY D2 (RESIDENTIAL). West Jordan's own Building & Safety Division Design Criteria page (last revised 07/2026) states: "WIND: Speed: All wind speeds listed below are 3-second gusts at 33 feet above the ground. Residential: 105 mph ... Exposure: Site specific (per Section 1609.4 of the IBC). Assumed to be 'C' unless justified." The page does not state whether this residential figure is a nominal or an ultimate design wind speed; this record reports the number as the City publishes it without resolving that question. The same page states ground snow loads must be determined for residential projects using the state's own tool at utahsnowload.usu.edu, per Utah Code 15A-3-202(19)-(20) (which separately replaces IRC Figure R301.2(3) with a 29-location Utah ground-snow-load table and directs the rest to that same study). Seismic Design Category is published as D2 for residential and D for commercial, with site-specific ground motions obtained from the ASCE Hazard Tool. Soils: frost depth 30 inches; residential bearing capacity 1,500 psf per IRC Table R401.4.1 unless a geotechnical report states otherwise. Climate Zone 5B; Weathering Severe; Termite None to Slight; Mean Annual Temperature 45 F.

No classification is set on this record. Utah's statewide amendment packet to the 2021 IRC (48,780 characters swept across all six Chapter 3, Part 2 sections) contains zero occurrences of "R908," "Chapter 9," or "R9" section numbers, so the state amendments do not touch the base code's reroofing provision. West Jordan's own Title 10 Building Regulations, which would be needed to confirm no local amendment exists, were not reachable this session: the City's code host, codelibrary.amlegal.com, returned an access-denied response rather than content. This record accordingly carries the state-level absence without asserting a classification.

7.45% COMBINED, WEST JORDAN LOCATION CODE 18-155 (SALT LAKE COUNTY). Per the Utah State Tax Commission's quarterly "Combined Sales and Use Tax Rates" chart (rates in effect as of July 1, 2026): State Sales & Use Tax 4.85%, Local Sales & Use Tax 1.00%, County Option Sales Tax 0.25%, Mass Transit Tax 0.30%, Additional Mass Transit Tax 0.25%, County Option Transportation 0.25%, Transportation Infrastructure 0.25%, County Public Transit 0.20%, and Botanical/Cultural/Zoo Tax 0.10%, totaling 7.45%. Under Utah Admin. Code R865-19S-58(2), a roofing contractor performing a furnish-and-install (repair or replacement) contract is the consumer of the materials and owes sales tax on the contractor's own purchase of them; the charge to the homeowner for the completed job, and the roofer's labor, is not itself taxed. R865-19S-58(2)(a): "The contractor or repairman who converts the personal property to real property is the consumer of tangible personal property regardless of the type of contract." Utah treats repair and replacement alike for this purpose; there is no repair/replacement split in the tax rule. A contractor may not separately state the tax it paid on materials as a line item on a customer invoice (Tax Commission Publication 42).
