Rooftop Solar Photovoltaic Permit
VerifiedRequired 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.
Verified 2026-07-20 · Source
Requirements
- Requires both a building permit (structural/mounting compliance) and an electrical permit (NEC-compliant wiring/interconnection), consistent with the general Colorado approach to rooftop PV
- Electrical portion governed by the National Electrical Code (2020 NEC as adopted, updated to the Colorado State Electrical Board's current recognized edition)
- Contractors must hold City of Castle Pines contractor licenses (Class E Electrical at minimum) plus applicable Colorado DORA licenses
- IFC fire-code amendments (Ordinance No. 23-02/23-07) explicitly allow the fire code official to exempt or modify fire apparatus access road requirements for solar photovoltaic power generation facilities
- Colorado HB21-1284 caps the aggregate of all City-imposed fees and charges related to installing an active solar energy system at $500.00 for a residential permit ($1,000.00 for commercial)

| Aggregate solar permit fee cap (commercial) | $1,000.00 maximum, per Colorado HB21-1284 | — |
| Electrical Permit Fee component | Governed by CRS 12-23-117, Section B (All Other/valuation-based fees), which explicitly names photovoltaic as an example of a non-square-footage installation billed on total installed cost | No Castle-Pines-specific dollar table was located as of this review. For reference only, neighboring Douglas County's own published Section B schedule (Castle Pines is not bound by this exact table, but it illustrates how CRS 12-23-117 Section B is typically implemented) charges $57 flat up to $2,000 valuation, then $5 per $1,000 (or fraction) plus $57 above that. Whatever Castle Pines' own equivalent electrical fee comes to, the City's combined total remains capped by the HB21-1284 aggregate limit above. |

EV Charger / EVSE Permit
VerifiedCastle 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.
Verified 2026-07-20 · Source
Requirements
- EV charger circuit installation is electrical work; apply via the SmartGov online portal using the standard Building/Electrical Permit Application
- If the installation is limited to a service amp change, it qualifies as a '1-Stop Permit' (no drawings required, typically issued within 24 hours) per the City's own Building Department FAQ
- If the installation involves new circuit wiring beyond a simple amp change, it is not explicitly listed as a 1-Stop category and likely follows the standard Plan Review Permit process instead
- Contractors must hold a current Colorado Electrical Board (DORA) license and a City of Castle Pines Class E Electrical Contractor registration (no City license fee for this class)
