Permit process note

Inspection requirements
The department maintains a dedicated Roofing Permit Required Inspection Policy that outlines the mandatory inspections for roofing projects.
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. About drip edge
Ice & water shield
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 barrier
Impact-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.
Wind design criteria
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)." Ground Snow Load is not a single printed figure; the resolution directs applicants to the department's site-specific GIS map instead. Applies to unincorporated Routt County.
Sales & use tax
3.9% combined in unincorporated Routt County (state 2.9% + county 1%). Always state-collected — the County's own page states plainly: "The State of Colorado administers the collection of sales tax for Routt County." The County separately administers a Building Use Tax on construction materials ("If you have Building Use Tax questions please contact the Routt County Building Department"), matching DR1002's state-collected-county table entry for Routt (county sales rate 1%, use tax rate 1%, applicable to "Motor Vehicles, Building Materials").
