EV Charger / EVSE Permit in Unincorporated Cassia County, Idaho
Cassia County does not issue electrical permits at all — per the county's own Permit Information page (cassia.gov/permit-information), 'For Electrical, Plumbing and HVAC Inspections & Permits' applicants must use the Idaho Division of Occupational and Professional Licenses (DOPL) online system, not the County. Installing a Level 2 or DC fast EV charger's dedicated circuit is therefore a state-issued Electrical Permit, not a county permit; a county Building Permit only applies if the installation involves new structural or mounting work — a new carport or accessory structure housing the charger, for example. DOPL's Homeowner Electrical Permit Application (dopl.idaho.gov/wp-content/uploads/2023/11/ELE-Home-Owner-Electrical-Permit-Application.pdf, revised 8/17/2022) carries the governing statewide figure on its Electrical Permit Worksheet (Fee Schedule): 'Existing Residence... $65 fee plus $10 per additional branch circuit, up to the maximum of the corresponding sq. of the building (one circuit is included in the $65.00).'

When you need this permit
- The electrical circuit/service work for an EV charger requires a State of Idaho Electrical Permit from the Idaho Division of Occupational and Professional Licenses (DOPL) (dopl.idaho.gov/ele/ele-permits-and-inspections/) — Cassia County does not issue or inspect electrical permits
- A county Building Permit is required only if the EV charger installation is paired with new construction (e.g., a carport, garage, or accessory structure) subject to the 2018 IBC/IRC as adopted by Cassia County
- Homeowners self-installing on their own residence may use Idaho's Homeowners Electrical permit path; contractors must hold a valid Idaho electrical contractor license Contractor
- Installation must comply with the National Electrical Code edition currently adopted by the State of Idaho Electrical Board

Tips
- Cassia County issues NO electrical permits of any kind — an EV charger circuit is a State of Idaho Division of Occupational and Professional Licenses (DOPL) permit (dopl.idaho.gov/ele/ele-permits-and-inspections/), the same as any other electrical work in the unincorporated county.
- Only get a county Building Permit involved if the charger installation is part of new construction (e.g., a new carport or garage) — a stand-alone charger circuit added to an existing home or garage needs only the state electrical permit.
- This mirrors how the county's Solar PV Permit works: the County handles structural/mounting, the State handles all electrical interconnection — see the solar-pv-permit entry for the same split.
- directly against DOPL's current Homeowner Electrical Permit Application/Fee Worksheet PDF: the $65 + $10/additional-branch-circuit figure for an existing-residence EVSE circuit is current and live (note the old dbs.idaho.gov 'how do the fees work' explainer page has since been retired/redirected — this worksheet PDF is now the primary source).
