Johnstown, Colorado has adopted: 2024 International Building Code (IBC) — Town of Johnstown Building Codes page, https://www.johnstownco.gov/211/Building-Codes, adopted per Ordinance No. 2025-274 (enacted September 15, 2025); 2024 International Residential Code (IRC), per the same ordinance and Building Codes page; 2024 International Fire Code (IFC); 2024 International Fuel Gas Code (IFGC); 2024 International Energy Conservation Code (IECC); 2024 International Mechanical Code (IMC); 2024 International Plumbing Code (IPC); 2023 National Electrical Code (NEC); Colorado Wildfire Resiliency Code, as adopted/referenced on the Town's Building Codes page; Colorado Model Electric and Solar Ready Code, as adopted/referenced on the Town's Building Codes page; Johnstown Municipal Code, Chapter 18 (Building Regulations); NOTE (data-integrity flag): Several individual project-specific pages on johnstownco.gov (Addition, Electrical, Roofing, Siding, Water Heater, Furnace, Air Conditioning, Basement Finish, Residential Solar) still display a stale 'applicable codes' footer citing the superseded 2018 I-Code suite (with only the NEC correctly updated to 2023) — this appears to be unupdated boilerplate predating Ordinance No. 2025-274's September 2025 adoption of the 2024 I-Codes. The Building Codes landing page (2024 codes) is treated as the current governing citation in this corpus; the discrepancy itself is disclosed rather than silently resolved, since the individual permit pages have not been corrected as of this review.. Local amendments apply — see the Johnstown overview page for the full list.
