Castle Pines, Colorado has adopted: 2021 International Building Code (IBC), Chapters 1-35 inclusive, exclusive of Appendices — adopted by Ordinance No. 23-02 (Feb. 28, 2023), City of Castle Pines Municipal Code Chapter 18, Article I; 2021 International Residential Code (IRC), 1st printing; Chapter 11 of the 2018 edition of the International Residential Code (retained separately alongside the 2021 IRC per Ordinance No. 23-02's title recitals — Chapter 11 of the IRC covers energy efficiency; the City kept the 2018 version of this chapter rather than adopting the 2021 IRC's Chapter 11 wholesale); 2020 National Electrical Code (NEC) — City of Castle Pines Municipal Code Chapter 18, Article III, Sec. 18-3-10, adopted pursuant to Title 31, Article 16, Part 2, C.R.S., 'as adopted, amended and updated to the most current edition by the Colorado State Electrical Board from time to time' per the authority in Article 23 of Title 12, C.R.S. — the City ties its NEC edition to whatever the Colorado State Electrical Board currently recognizes, rather than freezing a single print edition; 2021 International Mechanical Code (IMC), Chapters 1-15 inclusive — Article IV; 2021 International Plumbing Code (IPC), Chapters 1-13 inclusive — Article V; 2021 International Fire Code (IFC) — adopted by Ordinance No. 23-07 (2023); enforced by the South Metro Fire Rescue Fire Protection District, which Ordinance No. 23-02/23-07 designates as the Fire Marshal's Office / fire code official for the City; 2021 International Fuel Gas Code (IFGC); 2018 International Energy Conservation Code (IECC); 2021 International Swimming Pool and Spa Code (ISPSC); 2021 International Existing Building Code (IEBC); Note on code-adoption sourcing: the 2021 IBC/IRC/IMC/IPC/IFGC/IECC(2018)/ISPSC/IEBC + 2020 NEC list above is drawn directly from the recitals and Sections 1-5 of Ordinance No. 23-02 (a scanned/image PDF, read via rendered page images since it is not machine-text-extractable), the definitive code-adoption ordinance for Chapter 18 of the Municipal Code. The City's own Building Department FAQ page states more casually that the City 'is currently under the 2021 International Building Code/International Residential Code and the 2023 National Electrical Code' — this FAQ-page NEC reference (2023) is NOT used as the governing citation in this file because it conflicts with the specific, dated ordinance text (2020 NEC, floating to the State Electrical Board's current edition); the ordinance is treated as authoritative and the FAQ's '2023 NEC' is noted as a likely informal/rounded reference to whatever edition the State Electrical Board currently recognizes, consistent with the ordinance's own floating-adoption mechanism.; HB22-1362 (Colorado statewide energy code floor via updated model electrical/energy provisions): no City of Castle Pines ordinance, code-adoption page, or fee schedule references HB22-1362 or a specific electric-vehicle-readiness / electrification-readiness local amendment as of this review (Ordinance No. 23-02 predates HB22-1362's later compliance deadlines and does not mention it); not asserted as inapplicable, simply unconfirmed for this jurisdiction after checking the governing ordinance and the Building Department's public-facing pages directly.. Local amendments apply — see the Castle Pines overview page for the full list.
