Adopted code
Town of Gypsum Building Code requirements are codified under Title 15 of the Gypsum Municipal Code, which adopts the 2021 International Building Code (IBC), 2021 International Residential Code (IRC), 2021 International Mechanical Code (IMC), 2021 International Fuel Gas Code (IFGC), 2021 International Plumbing Code (IPC), 2018 International Energy Conservation Code (IECC), 2021 International Fire Code (IFC), 2023 National Electric Code (NEC), and the 2009 ICC/ANSI Accessibility Standards.
Drip edge
Required — Not separately amended by the Town of Gypsum. Sec. 15.01.040, the town's combined itemized amendment list to the 2021 International Building Code (items (a)-(w)) and 2021 International Residential Code (items (a)-(r), including R902.1 Class A roofing and R903.5 snow retention), does not delete or modify R905.2.8.5, so the base IRC drip-edge requirement stands as adopted code. About drip edge
Ice & water shield
Required — Town of Gypsum Municipal Code Sec. 15.01.040's printed climatic and geographic design criteria table lists "ICE BARRIER AIR UNDERLAYMENT = Yes" as the townwide determination. About ice & water barrier
Impact-resistant roofing
Not required — Town of Gypsum Municipal Code Sec. 15.01.040, the town's full itemized amendment list to the 2021 IBC and 2021 IRC, was read in full (closed by "(Ord. No. 2023-08, Sec. 1(Exh. A), 6-27-23; Ord. No. 2024-04, Sec. 4(Exh. A), 3-12-24; Ord. No. 2024-09, Sec. 1, 8-27-24)") and contains no provision addressing impact-resistant roofing, UL 2218, or hail. Item (n) mandates "Class A roofing only" for all roof coverings (R902.1), which is a fire classification, not an impact/hail-resistance mandate.
Wind design criteria
Town of Gypsum Municipal Code Sec. 15.01.040 prints a climatic and geographic design criteria table as: "CLIMATE ZONE = 6B; GROUND SNOW = 50; WIND SPEED = 115; TOPOGRAPHIC EFFECTS = B; SEISMIC = C; WEATHERING DESIGN = Severe; FROSTLINE = 42"; TERMITE = Slight; WINTER DESIGN TEMP = -5; FREEZING INDEX = 2500." Quoted as printed; the town's own "TOPOGRAPHIC EFFECTS" column is filled with "B" rather than the conventional Yes/No.
Sales & use tax
7.4% combined (state 2.9% + Eagle County 1.5% + Town of Gypsum 3%, self-administered — the Town's own Sales Tax Return form states "AMOUNT OF TOWN SALES TAX: 3% of LINE 4," filed directly with the Town of Gypsum at PO Box 130). The Town separately runs a residential-only Construction Use Tax Refund program: "For residential construction projects only, a Use Tax is collected at the time a building permit is issued. The Use Tax is charged at 3% of 50% of the valuation of residential construction," with a refund available for any sales tax already paid on building materials for that project (excluding tools, appliances, landscaping materials, fences, and similar non-structural items).
