Frederick, Colorado has adopted: 2024 International Building Code (IBC) — Town of Frederick Building Codes page; 2024 International Residential Code (IRC); 2024 International Fire Code (IFC); 2024 International Mechanical Code (IMC); 2024 International Fuel Gas Code (IFGC); 2024 International Plumbing Code (IPC); 2024 International Existing Building Code (IEBC); 2024 International Energy Conservation Code (IECC); 2024 International Swimming Pool and Spa Code (ISPSC); 2024 International Property Maintenance Code (IPMC); 2023 National Electrical Code (NEC); 2025 Colorado Wildfire Resiliency Code (as published by the State of Colorado Division of Fire Prevention and Control); Colorado Model Electric Ready and Solar Ready Code; All codes adopted with local amendments per Frederick Municipal Code, Chapter 18 (Buildings and Building Regulations) — Town of Frederick Building Codes page (frederickco.gov/141/Building-Codes); Note on code-cycle currency: the Town's own Residential/New Construction Building Permit Checklist (a submittal-requirements document, not the code-adoption page) still directs energy-code compliance via '2021 IECC Energy Code' (REScheck, energy rating report, or prescriptive HERS documentation), even though the live Building Codes page lists 2024 IECC as currently adopted — this is the same pattern seen in other Colorado jurisdictions in this corpus where a static submittal PDF lags the actively-maintained code-adoption webpage. The 2024 IBC/IRC/IECC/IMC/IPC/IFGC/IEBC/ISPSC/IPMC + 2023 NEC list from the Building Codes page is treated as the current, governing adopted-code list for this file; confirm current code edition directly with the Building Department (720-382-5516) before finalizing a code analysis for any specific project, since the checklist PDF may not yet be updated to match the webpage.. Local amendments apply — see the Frederick overview page for the full list.

The Town of Frederick Building Department issues its own building, electrical, mechanical, and plumbing permits for all work within town limits. Inspections are performed by Town staff or by CAA (Code Administration & Associates), described by the Town as its private building inspection partner.
