EV Charger / EVSE Permit (via General Building Permit) in Duncan, Arizona
Required for installation of an electric vehicle charging station in Duncan. As with solar PV (see this file's solar-pv-permit entry), the Town of Duncan does not maintain a separate electrical permit at all — its permitTypes are limited to a single general-purpose Building Permit, a Mobile Home Permit, a Zoning Use Permit, and a Floodplain Development Permit. An EV charger circuit or wall-mounted charging unit is therefore filed as a standard Building Permit on the Town's one-page 'Application for Building Permit and Inspection' form (checking 'Alteration' or 'Repair' as appropriate), billed on the Town's standard valuation-based fee formula — there is no distinct EV-charger/EVSE line anywhere in the Town's Schedule of Fees and Charges.

Tips
- Duncan has no separate electrical or EV-charger permit — the Town's only construction-related permits are the general Building Permit, Mobile Home Permit, Zoning Use Permit, and Floodplain Development Permit, so an EV charger installation is filed as a standard Building Permit.
- There is no distinct EV-charger/EVSE fee line anywhere in the Town's Schedule of Fees and Charges — the same $30.00 plus $4.11 per $1,000 valuation formula used for any other construction/alteration work applies.
- Because Duncan's adopted electrical code is the National Electrical Code referenced as 'current edition' (Town Code Article 7-3), a standard Level 2 charger installation should meet current NEC EV-charging provisions even though the Town's other codes (e.g., the 2006 IBC) are considerably older.
