THE 2021 INTERNATIONAL RESIDENTIAL CODE (WITH THE 2024 INTERNATIONAL BUILDING CODE), MANDATORY STATEWIDE UNDER UTAH LAW -- NOT A LOCAL MILLCREEK 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." Millcreek's own Building Department page independently lists its "CONSTRUCTION CODES (15A-2-1-103)" as "The 2024 edition of the International Building Code ... The 2021 edition of the International Residential Code ... Appendix AQ of the 2021 edition of the International Residential Code," plus the 2024 IPC, IMC, IFGC, the 2023 National Electrical Code, and the 2024 IECC and IEBC -- matching the state schedule exactly. 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 Millcreek. SEPARATELY, that same City page lists "The 2006 edition of the International Wildland-Urban Interface Code and Fire Hazard Severity Form" among its own adopted construction codes, and the City's dedicated Wildland Urban Interface page states: "Effective on January 1st 2026 Millcreek began administration of the Wild Land Urban Interface Code," publishing an associated WUI map and Fire Hazard Severity Form. That is the duty Utah Code 65A-8-203(9)(a) (enacted by 2025 HB 48, effective 2026-01-01) now imposes on every Utah municipality; the UWUIC's own Section 507 pulls in any roof covering replacement of 25 percent or more of the roof surface in a 12-month period, requiring the ignition-resistant covering used for new construction. This record does not establish whether that WUI code currently applies to any particular parcel in Millcreek, and its Section 507 covering standard is a FIRE rating, not an impact rating (see impact_resistant_required). The City's own local Municipal Code Title 15 (Buildings and Construction), which layers on top of the state code, was not independently reachable this session: its code host, millcreek.municipalcodeonline.com, returned an empty JavaScript shell rather than content.

Required — Utah's statewide amendment packet to the 2021 IRC (Title 15A, Chapter 3, Part 2, all six sections, 48,780 characters) 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, not Millcreek. This record points at the section rather than quoting its operative text, which has not been opened by this project. About drip edge

Required — Millcreek's own Climate and Geographic Design Criteria, published on the City's Building Department page and as a standalone PDF, states: "Ice Barrier Underlayment Required: Yes." The same table publishes an "Air Freezing Index" of 2500 (BF-Days) and a "Mean Annual Temperature" of 53.6 degrees Fahrenheit, both City-published figures a roofer would need alongside the underlayment requirement. About ice & water barrier

Not required — Millcreek's own "Required Inspections" list, published by the Building Department and read in full (fourteen named inspection stages: drop ceiling, drywall, electrical, final, footing, foundation, four-way, framing, gas line, insulation, rebar, mechanical, plumbing, power to panel, shear wall, and weather barrier), names no roof-covering, roof-sheathing, or mid-roof inspection stage. The "weather barrier" stage covers siding, brick, stucco, and lath, and is expressly described that way; it does not name a roof.

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, Millcreek's own Building Department page states that, effective January 1, 2026, the City began administering the 2006 Utah Wildland Urban Interface Code (the duty Utah's 2025 HB 48 now imposes on every municipality), publishing an associated WUI map and Fire Hazard Severity Form alongside the code text. That code, obtained directly from Millcreek's own site and read in full (154,416 characters), contains zero occurrences of "UL 2218," "FM 4473," "Class 4," "Class IV," and "hail"; its two "impact" hits concern the community's fire-protection delivery system and the visual and ecological impact of fuel modification, and its own roof-covering provision calls for "approved roof covering of noncombustible material," a fire test, not an impact test. So even where Millcreek's wildland-urban-interface administration reaches a given roof, it does not impose an impact-resistance requirement.

NO MINIMUM SIZE OR DOLLAR THRESHOLD IS STATED FOR A ROOF. Millcreek's own Building Department page lists the projects exempt from a building permit -- small detached accessory structures, low fences, small retaining walls, small water tanks, sidewalks and driveways, finish work, shallow pools, playground equipment, small window awnings, low decks, and small conex boxes -- and none of those exemptions names a roof covering or roof repair. The City's own FY26 Consolidated Fee Schedule prices "Re-Roof (Residential)" as a single flat $70.00 fee under Millcreek Municipal Code 15-08-030, with no square-footage or valuation break for the residential tier (only the separate commercial re-roof tier is priced by valuation). So on the City's own published schedule, any residential re-roof needs a permit regardless of size or cost.

RESIDENTIAL WIND SPEED 115 MPH (3-SECOND GUST); EXPOSURE CATEGORY B; NO SPECIAL WIND REGION; NO WINDBORNE DEBRIS ZONE; SEISMIC DESIGN CATEGORY VARIES D2 TO E BY LOCATION. Millcreek's own Building Department page and its standalone Climate and Geographic Design Criteria document state: "Wind Design: Wind Speed; 115 MPH, Exposure category B. Topographic Effects; No. Special Wind Region; No. Wind-borne Debris Zone; No. Seismic Design Category; Varies from D to E depending on location. Fault and Fault Study Areas; Yes, please see the Millcreek Interactive Map for specific locations." The same document does not state whether this wind figure is a nominal or an ultimate design wind speed; this record reports the number as the City publishes it without resolving that question. Ground snow load is 28 lb/ft^2 at or below 4,239 feet elevation (with a 100-foot tolerance), citing Utah's own snow load study for other elevations, consistent with Utah Code 15A-3-202(19)-(20)'s statewide ground-snow-load table. Subject to damage from: weathering severe, frost line depth 30 inches, termite slight to moderate. Air freezing index 2500 (BF-Days); mean annual temperature 53.6 degrees Fahrenheit; Climate Zone 5B.

THIS RECORD DOES NOT ASSIGN A LAYER-COUNT CLASSIFICATION. Utah's statewide amendment packet to the 2021 IRC (Title 15A, Chapter 3, Part 2, all six sections, 48,780 characters) contains zero occurrences of "R908," "Chapter 9," or any "R9xx" section number, so the state amendments do not touch the base code's reroofing provision. Millcreek's own Municipal Code, which would be needed to confirm no local amendment exists, was not reachable this session: the City's code host, millcreek.municipalcodeonline.com, returned an empty JavaScript shell (48,554 bytes, zero occurrences of "roof" or "chapter") rather than content. This record accordingly states the state-level absence without asserting what number, if any, governs a Millcreek reroof.

7.45% COMBINED, MILLCREEK LOCATION CODE 18-094 (SALT LAKE COUNTY, SAME P.S.D. AS THE REST OF THE 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).
