Full Breakdown
Adams County Ordinance No. 12 repeals the 2018 International Building Codes and 2017 National Electrical Code and replaces them with the 2024 International Building Codes and the 2023 National Electrical Code, effective July 1, 2026 under Resolution 2026-125. Section 1 adopts the codes by reference along with specific appendices, including Appendix AB (Permit Fees) from the 2024 International Residential Code, Appendix C (Group U Agriculture Buildings) and Appendix I (Patio Covers); any appendix not listed is excluded from adoption. Section 3 limits the ordinance to unincorporated Adams County: it is not enforced inside Thornton, Westminster, Brighton, Commerce City, Northglenn, Federal Heights or Aurora unless that city separately elects to apply it.
Section 5(3)(i) directs that electrical provisions shall follow the NEC requirements, deleting the International Building Code's electrical chapters 34 through 43 so the 2023 NEC governs wiring, service equipment and permit standards for construction work in the unincorporated area. Section 5(1) defines a Building Permit as the official county document authorizing construction activity under the primary and secondary codes, and names the Adams County Building Safety Division as the Authority Having Jurisdiction. 15 and the parallel IBC/IRC appeal sections, to hear disputes when the code official disapproves an application, refuses a permit, or misapplies the code; an applicant must file that appeal within 30 days of the disputed decision. Farm and ranch buildings still need electrical permits even though they are exempt from the separate county fire code.
Violations & Fines
Ordinance No. 12 Section 6 makes any violation punishable under C.R.S. § 30-28-409 by a fine of up to $1,000 for each separate violation, with each day the illegal activity continues counted as a new offense. The county can pursue this penalty alongside any other remedy available under federal, state or local law, at the enforcing agency's discretion.
