Electric Vehicle Charging Station Permit
VerifiedThe Town of Crested Butte does not publish a standalone EV charger/EVSE permit application or fee line distinct from its general Electrical Permit -- checked the Building Department page, Town Code Chapter 18 Article 5 (Electrical Code), and the 2026 Fee Schedule directly; none name a separate EV charger permit or fee. Installing or retrofitting an EV charger (or completing the wiring to an already-provisioned EV-Ready circuit) is electrical work and is processed as a standard Electrical Permit under the 2023 NEC as adopted (Town Code Sec. 18-5), billed on the same valuation-based Building Permit fee table used for all electrical work in Crested Butte. This is distinct from the EV-Ready parking-space wiring mandate that applies automatically to new residential construction and Level 3 alterations (documented in this file's residential-building-permit and residential-addition-remodel entries) -- that mandate provisions the circuit/receptacle during new construction, while this entry covers permitting an EV charger installation itself, whether as part of new construction or a standalone retrofit to an existing home.

- For a STANDALONE EV charger retrofit to an existing home not otherwise triggering a Level 3 alteration, a standard Electrical Permit is required for the new circuit/charger installation
- Current Gunnison County building contractor license required for contractor-performed work
- Fees billed under the same valuation-based Building Permit fee table as other electrical work; no separate EV-charger-specific fee line item found in the 2026 Fee Schedule

If the parcel falls within a mapped Class 1/Class 2 Colorado Wildfire Resiliency Code fire hazard area and the re-roof replaces more than 25% of the existing roof covering, the entire roof must meet CWRC Class A roof-covering and valley-flashing requirements.

VerifiedRequired for solar photovoltaic installation in Crested Butte, using the Town's dedicated Solar Permit Application. Requires drawings showing panel locations, solar specifications with required emergency shut-off and electrical code requirements, and a structural engineer stamped letter confirming the existing roof will remain structurally sound.

Building Relocation and Demolition Permit
VerifiedRequired to demolish or relocate any primary or accessory structure larger than 200 square feet in Crested Butte.

- Structures 200 sq ft or smaller are not subject to this permit track per the Town's own application scope language
- Historic structures may be eligible for a variance under CWRC Section 102.9 if a required upgrade would jeopardize continued historic designation, but this is a separate CWRC provision, not a demolition-permit exemption
