THE 2021 INTERNATIONAL RESIDENTIAL CODE, MANDATORY STATEWIDE UNDER UTAH LAW -- NOT A LOCAL SOUTH JORDAN ADOPTION, AND CONFIRMED BY THE CITY'S OWN CURRENT STATEMENTS. 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." South Jordan's own Building Department page independently lists "Applicable Building Codes in use in South Jordan City" and names the 2021 International Residential Code (including Appendix E and Q) first among them, alongside the current-edition International Building, Plumbing, Mechanical and Fuel Gas Codes and a pointer to "Applicable Utah State Amendments." A separate, signed "Re-Roof Requirements Official Statement" issued by the City's Chief Building Official also lists the 2021 International Residential Code, though that same document names the 2021 International Building Code where the City's current webpage names the 2024 edition -- a discrepancy this record discloses without resolving, and one that does not affect the residential roofing edition, which both documents state as 2021. 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 South Jordan. The City's own Title 15 Buildings and Construction, which would be needed to confirm whether any further local amendment exists, was not independently reachable this session: its code host, southjordan.municipalcodeonline.com, returned an empty JavaScript shell (zero occurrences of "roof," "building," or "Title 15" across 48,613 bytes) rather than content. Separately, Utah Code 65A-8-203(9)(a) (enacted by HB 48, effective 2026-01-01) required 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. South Jordan's City Council did so: Resolution R2025-53, adopting the 2006 Utah Wildland-Urban Interface Code, and Resolution R2025-54, adopting a corresponding WUI map, both passed 5-0 on December 2, 2025. The Fire Chief's presentation to the Council described the map as covering newly annexed undeveloped land on the city's west side, portions of Bingham Creek, and especially the Jordan River corridor, and stated that the City's own map is separate from a further high-risk boundary map the state is developing, which the presentation said reaches only "a very small portion of South Jordan's far west side." This record does not reproduce the map itself and does not determine whether any particular parcel falls inside a designated area.

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; the only two local IRC Chapter 9 amendments the Legislature has authorized anywhere in Utah apply to Park City and Sandy City, neither of which is South Jordan. This record points at the section rather than quoting its operative text, which has not been opened by this project. About drip edge

Required — South Jordan's Building Department publishes a signed "Re-Roof Requirements Official Statement," over the Chief Building Official's signature, stating: "Referenced codes include requirements for ventilation, ice and water shield, drainage performance and other criteria that must be followed," and that all roof work "are required to follow all the State and City adopted codes." The Department's own Design Criteria page separately states a Frost Depth of "30 inches minimum from the bottom of the footing to the finished grade," published alongside the same code list. 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, South Jordan has adopted the 2006 Utah Wildland Urban Interface Code and a WUI zone map (Resolutions R2025-53 and R2025-54, both passed 5-0 on December 2, 2025), covering newly annexed land on the city's west side, portions of Bingham Creek and the Jordan River corridor. That code is fire-only: counted across its full 118,402 characters, "UL 2218," "FM 4473," "Class 4," "Class IV" and "hail" are each zero, and its two "impact" hits concern community fire protection and ecological effects of fuel modification, not roofing materials. A wildfire code adoption implies nothing about hail impact resistance.

WIND LOADS DETERMINED IN ACCORDANCE WITH CHAPTERS 26-30 OF ASCE 7, EXPOSURE CATEGORY C. South Jordan's Building Department page states, under "Design Criteria in South Jordan City": "Wind loads shall be determined in accordance with Chapters 26-30 of ASCE 7. Exposure C." The same page states snow loads "shall be determined in accordance with Chapter 7 of ASCE 7," a Seismic Zone of "D," and a Frost Depth of "30 inches minimum from the bottom of the footing to the finished grade." The page does not publish a numeric design wind speed, ground snow load figure, or state whether the wind figure is nominal or ultimate; this record reports the City's criteria exactly as published without resolving those questions. Separately, Utah Code 15A-3-202(19)-(20) replaces IRC Figure R301.2(3) with a statewide 29-location ground-snow-load table and directs any location not listed to the state's own snow load study tool at utahsnowload.usu.edu.

NO CLASSIFICATION VALUE IS SET HERE PENDING FURTHER CORPUS-WIDE RESEARCH. 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. South Jordan's own Title 15 Buildings and Construction, which would be needed to confirm no local amendment exists, was not reachable this session: the City's code host, southjordan.municipalcodeonline.com, returned an empty JavaScript shell (zero occurrences of "roof," "building" or "Title 15" across 48,613 bytes) rather than content. This record accordingly carries the state-level absence without asserting a classification.

7.45% COMBINED, SOUTH JORDAN LOCATION CODE 18-138 (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).
