Adopted code
The Routt County Regional Building Department adopted the 2021 ICC Series for the IBC, IRC, IECC, IEBC, IFGC, IPC, IMC, and IPMC effective January 1, 2024, along with portions of the 2021 IWUIC and the Colorado Model State Electric and Solar Ready Code.
Drip edge
Required — Not separately amended for unincorporated Routt County. The county's adoption resolution adopts the 2021 IRC by reference (with a 2024 IRC cross-reference for seismic design per the same table) with amendments and deletions set out in the resolution's own IRC amendments section (the same adoption-clause-then-amendments-section structure as the City of Steamboat Springs' and Town of Hayden's companion resolutions); that section does not delete or modify R905.2.8.5, so the base IRC drip-edge requirement stands as adopted code for unincorporated Routt County.

Required — Routt County Un-Incorporated 2021 ICC Building Code Adoption resolution, Table R301.2(1) as amended: "Ice Shield Underlayment Required – Yes per IRC Section R905.1.2 Ice Barriers." Applies to unincorporated Routt County.
About ice & water barrierImpact-resistant roofing
Not required — No unincorporated-Routt-County amendment mandates Class 4 / UL 2218 impact-resistant roof coverings. The county's adoption resolution (39pp, OCR'd where scanned) was reviewed for its IRC amendments section and contains no UL 2218 or Class 4 reference.

The Routt County Un-Incorporated 2021 ICC Building Code Adoption resolution (recorded 12/11/2024, Reception #857748) amends Table R301.2(1) Climatic and Geographic Design Criteria to read: "Wind Speed – 115 MPH (ultimate design wind speed)," "Topographic Effects – No," "Seismic Design Category Per ASCE 7-22 Hazard Map as referenced by the 2024 IRC," "Climate Zone 7," "Subject to Damage by Weathering – Severe," "Subject to Damage by Frost line Depth – 48 inches (1220mm)," "Subject to Damage by Termite – None to slight," "Subject to Damage by Decay – None to slight," "Outdoor Winter Design Dry-Bulb Temperature – -15ºF (-26ºC)," "Flood Hazards – FIRM, February 4, 2005," "Air Freezing Index – Steamboat 2239," "Mean Annual Temperature – 40-45ºF (4.5-7.2ºC)."
