"19. Section R301 is amended to add as follows: Table R301.2(1) -- FLAT ROOF SNOW LOAD REPLACES GROUND SNOW LOAD as determined by Garfield County snow load based on elevation: To 7000 ft. 40 psf; 7001 to 8000 ft. 50 psf; 8001 to 9000 ft. 75 psf; 9001 to 10,000 ft. 100 psf...

WINTER DESIGN TEMPERATURE - minus 2 to 7000 ft.; minus 16 over 7000 ft. of elevation... AIR FREEZING INDEX - 2500 deg F-days to 7000 ft. elevation; above 7000 ft. to be determined by Building Official. MEAN ANNUAL TEMP - Variable." (Garfield County Building Code Resolution of 2017, Resolution No. 2017-23, Exhibit A, Alteration to International Codes, Part A / Sec. R301 amendment. Corroborated by the county's own "Building Requirements -- Residential Projects" summary sheet, effective October 15, 2018 and updated June 12, 2023, which reprints the same elevation-tiered figures and adds a 40 PSF roof load / Load Duration = 1.0.) Elevation-tiered snow load is a defining feature of Garfield County's amendment -- unlike flat-elevation Front Range towns, snow load (and frost depth, winter design temp, air freezing index) scale in steps keyed to the property's elevation band.

3.9% combined for UNINCORPORATED Garfield County (state 2.9% + Garfield County 1%; no RTA — the Roaring Fork RTA's boundary is defined by specific city limits (Carbondale/Glenwood Springs at 1%, Basalt/New Castle at 0.80%) that do not extend to unincorporated county area, and no county-level use tax applies to construction materials). This figure applies only to permits issued in unincorporated Garfield County; permits within Carbondale, Glenwood Springs, New Castle, Parachute, Rifle, or Silt town/city limits are governed by that municipality's own combined rate (state + county 1% + the town/city's own rate) instead. Re-verified 2026-08-27 against the January 2026 edition of Colorado Department of Revenue form DR 1002, read from a rendered image of its tables rather than from extracted text: the state, county and city figures above match that edition exactly. Where the text above names the June 19, 2019 revision of DR 1002, that describes the edition the figure was originally taken from and is not a current citation.
