Centennial, Colorado has adopted: Colorado has no statewide mandatory building code for general construction; code adoption is a home-rule/local decision that varies by city and county. Applicants must confirm the specific edition and local amendments adopted by their own city — do not assume any other Colorado jurisdiction's adopted codes apply to Centennial. Source: City of Centennial Building Division page (jurisdiction-specific adopted-codes list, current as of this review).; Colorado HB22-1362 (Building Greenhouse Gas Emissions, signed June 2, 2022) establishes a statewide ENERGY-CODE FLOOR only (not a full building code): before July 1, 2026, municipalities and counties that update their building codes must adopt and enforce an energy code achieving equivalent-or-better efficiency than the 2021 IECC and the state Energy Code Board's model Electric and Solar Ready Code; on/after July 1, 2026 they must meet the Board's model Low Energy and Carbon Code. Centennial's currently adopted 2021 IECC satisfies this floor as of this review.
