Required

The 2021 edition of the International Residential Code applies statewide by force of Utah Code 15A-2-103(1)(b); the IBC adopted alongside it is a different edition, the 2024 IBC -- the two should not be conflated. 15A-1-204(1)(a) requires "the state and each political subdivision of the state" to follow the State Construction Code, and 15A-1-204(8) bars a political subdivision from adopting or enforcing anything "more restrictive than, the State Construction Code" on a subject it addresses, except as expressly provided in state law. What is expressly provided for Park City is Utah Code 15A-4-206, the only codified local IRC amendment in the entire state naming Park City: it deletes and replaces IRC Section R905.7 (Wood shingles) and R905.8 (Wood shakes) with a wildfire hazard-severity rating scale -- "Wood roof covering is prohibited in areas with a combined rating of more than 11" -- and separately adopts "Appendix P, of the 2006 IRC" and Appendix K. That is a wildfire/material-prohibition rule, not an impact-resistance or layer-count rule, and it is stated here as the statute states it: Appendix P is frozen to the 2006 IRC even though the state's general residential base is the 2021 IRC; this record does not reconcile that gap (Utah Code 15A-1-204(9) grandfathers only pre-2015 local rules and does not address it either). Separately, Park City Municipal Code Chapter 11-21 (Ordinance 2016-31, adopted June 30, 2016, as amended by Ordinance 2020-35, adopted July 9, 2020) adopts "The 2006 Utah Wildland-Urban Interface Code, as adopted by the State of Utah," applying to "all the lands within the city limits of Park City designated by the Utah Division of Forestry, Fire and State Lands as Wildland-Urban Interface," with compliance triggered for new construction, additions, and remodels valued over $50,000. The ordinance itself requires new buildings and qualifying remodels in that area to use a Class A roof covering and prohibits wood shingle or shake materials -- a fire rating, not an impact rating. Since 2026-01-01, Utah Code 65A-8-203(9)(a) (enacted by 2025's HB 48) makes adoption and enforcement of a state-authorized WUI code a duty for every Utah municipality; Park City's 2016/2020 ordinance already satisfies that duty. The 2006 Utah Wildland-Urban Interface Code's own Section 507 separately provides that a roof covering with 25 percent or more replaced in a 12-month period must meet the ignition-resistant standard required for new construction; this record discloses that model trigger without reconciling it against Park City's own stated $50,000 remodel-value threshold, which is a different test. This record also does not decide whether tying WUI applicability to the state's own Division of Forestry, Fire and State Lands hazard designation, rather than a separately declared and clerk-filed City zone map, satisfies the WUI code's own requirement that the legislative body itself declare the wildland-urban interface area.

Required — Neither Utah's statewide IRC amendments nor Park City's own lawful local amendment vehicle (Utah Code 15A-4-206, the only codified local IRC change naming Park City) touches drip edge; the base 2021 IRC's own drip edge provision applies in Park City unmodified. About drip edge

Not required — Utah's statewide IRC amendments (Utah Code Title 15A Chapter 3, Part 2) and Park City's own local amendments (Utah Code 15A-4-206 and Park City Municipal Code Chapter 11-21) contain no UL 2218 or Class 4 impact-resistance requirement. Park City's local amendments instead prohibit wood shingles and shakes above a wildfire hazard rating and require a Class A roof covering in its designated wildfire area -- a fire rating under a different standard, and not a substitute for one.

No dollar-value or square-footage exemption specific to roof repair was found in the Park City materials read this session. The City's own construction and development fee schedule prices a building permit generically by project valuation (0.61 percent of the total valuation of construction, subject to a minimum) rather than by a roofing-specific threshold, and does not name roofing in any exemption. Separately, Park City's own Wildland-Urban Interface ordinance (Chapter 11-21) sets its own applicability line for that code at new construction, additions, and remodels valued over $50,000, which is not a general roofing-permit threshold.

Utah's statewide IRC amendments do not fill in a wind speed or ice-barrier column for any jurisdiction; those remain each jurisdiction's own entries. Park City's own published Climatic and Geographic Design Criteria table (Building Department, revised June 27, 2022) gives: basic wind speed 115 mph, topographic wind effects not required, not in a special wind region, not in a wind-borne debris zone, seismic design category D or D1, and mean annual temperature 42 F. Ground snow load is not a fixed figure in Park City's own table; it directs users to the Utah State University Ground Snow Load Map (the same study referenced by the state's own Table R301.2(3), which does not separately list Park City among its 29 named locations).

Utah's statewide IRC amendment package (Title 15A Chapter 3, Part 2) amends nothing in IRC Chapter 9, and Park City's only lawful local IRC amendment vehicle, Utah Code 15A-4-206, amends only R905.7, R905.8, and Appendices P and K -- it does not touch R908 or any other reroofing provision. The base 2021 IRC's own reroofing section, R908.3.1.1, therefore governs in Park City; this record points to that section rather than restating its content, which was not opened for this record.

Not amended for Park City. Utah's statewide IRC amendment package (Title 15A Chapter 3, Part 2) amends nothing in IRC Chapter 8, and Park City's only lawful local IRC amendment vehicle, Utah Code 15A-4-206, is limited to R905.7, R905.8, and Appendices P and K -- it touches no roof-deck-sheathing provision. Under 15A-1-204(8), Park City may not adopt a different roof-sheathing standard outside that Chapter 4 vehicle. The base 2021 IRC's Chapter 8 roof sheathing provisions apply unmodified.

In Utah a roofing contractor performing a furnish-and-install contract is the consumer of the materials it converts to real property and pays sales tax on its own purchase of those materials; the charge to the homeowner for installed roofing is not separately taxable, and a repair is taxed exactly like a replacement, since both convert personal property to real property (Utah Admin. Code R865-19S-58; Utah Code 59-12-103(1)(g) taxes only services on tangible personal property, not real property or labor performed on it). The combined sales tax rate for Park City, per the Utah State Tax Commission's own quarterly Combined Sales and Use Tax Rate chart (rates in effect July 1, 2026, location code 22-030), is 9.55 percent: 4.85 percent state, 1.00 percent local sales, 0.25 percent county option, 0.30 percent mass transit, 0.25 percent additional mass transit, 0.25 percent county option transportation, 0.25 percent transportation infrastructure, 0.20 percent county public transit, 0.50 percent rural hospital, 0.10 percent botanical/cultural/zoo, and 1.60 percent resort community tax. The Commission's own chart notes that the Snyderville Basin Transit District, in unincorporated Summit County, uses Park City as its mailing city and generally ZIP code 84098, and shares this same rate.
