Regulatory framework
The code baseline for Montrose County.
Montrose County's current official code resolution for unincorporated areas adopts the 2018 International Building Code, 2018 International Residential Code, 2018 International Energy Conservation Code, 2018 International Property Maintenance Code, 2018 International Existing Building Code provisions for relocated/moved buildings, and the NCSBCS/ANSI A225.1-1994 Non-Permanent Foundations Guide for Manufactured Housing, as amended by the County. The International Fire Code is enforced by the applicable local fire-protection district; Colorado State electrical and plumbing permits and codes are enforced by the State. The County's 2026 materials do not show a newer building-code adoption.
