Drip edge
Required — Not separately amended by the Town of Avon. Sec. 15.10.020 states: "The 2021 International Residential Code is amended and changed as described in Sections 15.10.030 through 15.10.110 of this Chapter" -- a closed, self-declared list of nine amended sections (R101, R104, R108, R109, R110, R112, R114, Table R301.2, Appendix AT), none of which touch R905.2.8.5, so the base IRC drip-edge requirement stands as adopted code.

Town of Avon Municipal Code Sec. 15.10.100 amends Table R301.2 of the 2021 International Residential Code to read: "Ground and Snow Loads (psf) = <= 8,200 ft.: 75; > 8,200 ft.: 90; Wind Design Speed (mph) = 115; Topographical effects = No; Special wind region = No; Wind borne debris zone = No; Seismic Design Category = B; Weathering = SEVERE; Frost line depth = 48''; Termite = None to Slight; Flood Hazards = Slight; Air Freezing Index = 2500; Mean Annual Temp = 37.4."
