The Town of Carbondale has adopted the 2021 International Building Code, International Residential Code, International Plumbing Code, International Mechanical Code, International Energy Conservation Code, International Existing Building Code, International Fuel Gas Code, and International Swimming Pool and Spa Code, along with the most current electrical code adopted by the State of Colorado, effective July 1, 2025.
Drip edge
Required — Not separately amended by the Town of Carbondale. Sec. 18-3-20, the town's full itemized amendment list to the International Residential Code (62 numbered items, Chapter 1 through Appendix K), 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 Carbondale Municipal Code Sec. 18-3-20 item (7), amended Table R301.2, lists "Ice Barrier Underlayment Required = Yes" as the townwide determination. About ice & water barrier
Impact-resistant roofing
Not required — Town of Carbondale Municipal Code Sec. 18-3-20, the town's full itemized amendment list to the International Residential Code, was read in full (62 numbered items, closed by "(Ord. No. 3-2025, Sec. 3(Exh. C), 4-4-2025)") and contains no provision addressing impact-resistant roofing, UL 2218, Class 4 shingles, or hail. Item (62) references an "impact insulation class (IIC)" rating, but that is an acoustic (sound-transmission) standard for floor/ceiling assemblies, not a roof-covering impact/hail-resistance requirement.
Wind design criteria
Town of Carbondale Municipal Code Sec. 18-3-20 item (7) amends Table R301.2 of the International Residential Code to read: "Ground Snow Load = 50psf*; Wind Speed = 105 (mph); Topographic effects = No; Special wind region = No; Windborne debris zone = No; Seismic Design Category = C; Weathering = Severe; Frost line depth = 36"; Termite = None to Slight; Flood Hazards = 1986; Air Freezing Index = 2500 Degree days (F); Mean Annual Temp = 45°."

Sales & use tax
10.15% combined effective 1/1/2026 for ordinary retail sales (Town of Carbondale 3.5% + State of Colorado 2.9% + Garfield County 1.0% + Regional Transportation Authority (RTA) 1.0% + Confluence Early Childhood Service District 0.25% + Carbondale and Rural Fire Protection District 1.5%) — per the Town's own page, ALL SIX components, including the Town's own 3.5%, are now "Paid to the State of Colorado": Carbondale (a home-rule town) transitioned its general sales tax to STATE COLLECTION (a 2024 change; the Town's site still carries a "SALES TAX NOTICE 2024" about the transition). Construction materials are taxed differently: the Town itself still directly collects a separate Building Use Tax — "Must be paid to the Town by anyone performing construction work which requires a Carbondale building permit, for the cost of construction materials used, stored, or consumed. Building use tax is collected prior to issuance of the building permit. The use tax amount paid is 3.5% of the estimated amount of construction materials to be used in the project... Municipal sales tax is NOT charged to the buyer if the building permit is presented to the seller when the building materials are being purchased. County, State, and RTA sales taxes are still charged" on top of that 3.5% town use tax.
