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 record 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 the last verification (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.
