Codes adopted
Colorado has no statewide-mandated building code edition. Under the Colorado Constitution's home-rule provisions (art. XX, home rule for municipalities since 1902; home rule for counties since 1970), building codes and zoning are an enumerated home-rule charter power, so cities and counties adopt and amend their own construction codes independently — predominantly the I-Codes, with editions and local amendments varying by jurisdiction. The one statewide floor is for energy: HB22-1362 (2022) created the Energy Code Board (jointly appointed by the Colorado Energy Office and the Department of Local Affairs) and requires that, on or after July 1, 2023 and before July 1, 2026, any municipality or county that adopts or updates a building code must adopt and enforce an energy code achieving performance equivalent to or better than the 2021 IECC together with the board's Model Electric Ready and Solar Ready Code (which includes electric-ready, EV-ready, and solar-ready provisions); from July 1, 2026 onward the floor shifts to the board's Model Low Energy and Carbon Code or an equivalent. Electrical and plumbing permitting defaults to the Colorado State Electrical Board and State Plumbing Board (within DORA's Division of Professions and Occupations) — the state issues permits and inspects statewide except in counties/jurisdictions that operate their own certified Electrical or Plumbing Inspection Program, in which case the local program has authority instead. Always confirm the currently adopted code edition, local amendments, and inspection authority (state board vs. local program) with the specific jurisdiction before submitting plans.
- 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.
Permit types & fees
New Residential Building Permit
Required for new single-family or duplex residential construction in Castle Pines. Categorized as a Plan Review Permit under the 2021 IRC/IBC as locally adopted; requires two identical, scaled, stamped drawing sets.
Residential Addition / Remodel Permit
Required for additions and remodels to existing single-family dwellings. Categorized as a Plan Review Permit under the 2021 IRC as locally adopted.
Electrical Permit
Required for electrical service changes, wiring, and equipment installation in Castle Pines. Governed by the National Electrical Code as adopted (2020 NEC base edition, floating to the Colorado State Electrical Board's current recognized edition). Fees follow the Colorado state-mandated schedule rather than a City-set table; electrical contractors need only a current Colorado Electrical Board (DORA) license (no City license fee) plus City contractor registration.
Plumbing Permit
Required for plumbing installation, alteration, or repair. Governed by the 2021 International Plumbing Code as locally adopted. Plumbing contractors must hold a Colorado Plumbing Board (DORA) Master Plumber license plus a City of Castle Pines Class F Plumbing Contractor registration ($50/year).
Mechanical / HVAC Permit
Required for heating, cooling, and ventilation equipment installation or replacement. Governed by the 2021 International Mechanical Code as adopted. Air Conditioning System and Furnace Replacement qualify as 1-Stop Permits.
Reroof Permit
Required for any re-roofing project or roof repair replacing more than 100 square feet of roofing. Qualifies as a 1-Stop Permit (no drawings required). Governed by the 2021 IRC/IBC and the City's own Residential Roofing Requirements handout, which explicitly waives the ice-barrier-underlayment requirement.
Rooftop Solar Photovoltaic Permit
Required for rooftop photovoltaic system installations. Not explicitly listed among the City's 1-Stop Permit examples, so it is treated as falling under the Plan Review Permit track (structural roof-mounting plus electrical interconnection). Electrical portion governed by the NEC as adopted; a Colorado statutory fee cap applies to the aggregate of all local solar permit fees.
Demolition Permit
Required for interior or whole-structure demolition. Listed on the Building Permit Application as a distinct permit type and separately as a 1-Stop Permit example on the Building Department FAQ.
Commercial Alteration / Tenant Improvement Permit
Required for commercial tenant finish and alteration work. Listed as 'Commercial Alteration' on the City's Building Permit Application; categorized under the Plan Review Permit track with the City's longer 10-business-day commercial review timeline.
Deck / Patio Cover / Carport Permit
Required for decks, carports, patio covers/pergolas, and fences over seven feet. Categorized as a Plan Review Permit under the 2021 IRC as locally adopted.
EV Charger / EVSE Permit
Castle Pines has no standalone EV-charger/EVSE permit type or fee line item. Installing electric vehicle charging equipment is electrical work, and per this file's own electrical-permit entry, is issued directly by the City (not routed to a state agency) under the National Electrical Code as adopted (2020 NEC base edition, floating to the Colorado State Electrical Board's current recognized edition per Municipal Code Sec. 18-3-10). The City's own Building Department FAQ lists 'Electrical Service Amp Change' among its '1-Stop Permits' (no drawings required, typically issued within 24 hours), but does not separately list EV chargers, EVSE, or electric vehicle charging as a named 1-Stop category -- checked the FAQ page directly, no mention found. A simple EV charger circuit addition that does NOT involve a service amp change would therefore likely require the standard (non-1-Stop) electrical permit process rather than the expedited 24-hour track. Fees follow the Colorado state-mandated schedule (CRS 12-23-117(3)) rather than a City-set table, same as all electrical work -- this is a real, currently-in-force governing fee mechanism, confirmed directly against the City's own 2026 Fee Schedule, which lists the electrical permit line item as 'As outlined by State Statute' rather than substituting a City dollar table. Colorado's HB24-1173 (C.R.S. Sec. 31-23-316, effective August 7, 2024) requires municipalities with population 10,000+ to adopt a standardized EV-charging permitting process, adopt the state's model land use code, or formally opt out, by December 31, 2025; Castle Pines' 2020 Census population (11,036) exceeds this threshold. Checked directly on 2026-07-20 against the City's Municode library (library.municode.com/co/castle_pines), City Council/Planning Commission agenda archives, and the Colorado Energy Office's EV-charging-permitting page -- no adopted ordinance, resolution, model-code adoption, or opt-out resolution referencing HB24-1173 or C.R.S. Sec. 31-23-316 was found published by the City as of this review; this is reported as a genuine compliance-status gap in Castle Pines' public materials, not an inferred status.

Tips & gotchas
- Castle Pines is a home-rule city (incorporated 2008) with its own Building Department; Douglas County's Building Division does not issue permits inside Castle Pines city limits — do not assume county rules or fees apply to a Castle Pines address.
- Castle Pines splits ALL building-permit work into exactly two tracks: '1-Stop Permits' (no drawings, typically issued within 24 hours) and 'Plan Review Permits' (two scaled drawing sets, 5-day residential / 10-day commercial review). Identifying which track a project falls into is the single most important scheduling factor — check the City's published example lists rather than assuming.
- Electrical permitting in Castle Pines is unusually state-deferred for a Colorado home-rule city: the NEC edition itself floats to whatever the Colorado State Electrical Board currently recognizes, the City's own 2026 Fee Schedule lists Electrical Permit Fees as 'As outlined by State Statute' rather than a City table, and the City charges $0.00 for its own Class E Electrical Contractor registration (just requires proof of the State DORA license). Plumbing is only partially state-deferred: a Colorado Plumbing Board Master Plumber license is required, but the City still charges its own $50/year Class F local registration fee on top.
- Castle Pines explicitly does NOT require ice barrier underlayment for reroofing, per the City's own Residential Roofing Requirements handout — a notable local departure worth flagging since several neighboring/peer Colorado jurisdictions do require it.
- No formal Climatic and Geographic Design Criteria chart (ground snow load, seismic design category, frost depth) was found published anywhere on the City's site after full chasing — only a 105 mph/3-second-gust wind speed and Wind Exposure Category B figure (from the roofing requirements handout). This is a genuine information gap in the City's public-facing documentation, not an oversight in this research; do not substitute a neighboring jurisdiction's chart.
- The City's Building Department FAQ page states the City is 'currently under the 2021 IBC/IRC and the 2023 National Electrical Code,' but the governing code-adoption ordinance (No. 23-02) specifies the 2020 NEC edition, floating to whatever the Colorado State Electrical Board currently recognizes — the ordinance is treated as authoritative in this file; the FAQ's '2023 NEC' phrasing is likely an informal reference to the State Electrical Board's current recognized edition rather than a distinct City re-adoption.
- Work started before a permit is issued triggers a 100% penalty fee (full doubling of the building permit fee) under a local amendment to IBC Section 109.4 — this is a real, specific local amendment, not the generic 'may be subject to a stop-work order' language seen in many jurisdictions' code recitals.
- The 2026 Fee Schedule PDF (effective document dated May 2026, cited throughout this file) supersedes the older Table 1-A fee schedule (dated 05/11, roughly 2011) and the 2020 general Fee Schedule found earlier in this research — always confirm you are pricing off the current-year schedule linked from the City's live Building Permits and Inspection Services page, since Castle Pines republishes this PDF annually at a dated upload path.
- No dedicated ADU (Accessory Dwelling Unit) permit type or ordinance provision was found; the City handles accessory structures generically (Accessory Structures guide, Pole Barns guide) without a distinct ADU zoning/permitting category as of this review — not modeled as its own permitType in this file.
- Right-of-way and grading/erosion/sediment-control permits (GESC) are a genuinely separate Public Works permitting track under the City's Roadway Design and Construction Standards, distinct from Building Division building permits — not modeled as permitTypes in this file.
- Solar photovoltaic permits are not named in either the City's 1-Stop or Plan Review example lists, and no dedicated solar submittal checklist was found; Colorado's statewide HB21-1284 fee cap ($500 residential / $1,000 commercial aggregate) is the clearest governing constraint located for this permit type after full chasing.
- Castle Pines' site occasionally routes through Municode's JavaScript-rendered library.municode.com viewer, which cannot be scraped as plain text; the governing code-adoption ordinances (No. 23-02, No. 23-07) are scanned/image-based PDFs with zero machine-extractable text and were read via rendered page images rather than pdftotext, per this project's zero-tolerance policy for chasing every recovery avenue before treating a fact as unverifiable.
