Electric Vehicle (EV) Charging Station / EVSE Permit in Unincorporated Twin Falls County, Idaho

Unincorporated Twin Falls County does not itself issue electrical permits. Per the county's own building-permit documentation (confirmed on the paired solar-pv-permit entry in this file), electrical permitting and inspection -- which covers EV charging station/EVSE circuit installation -- is handled by the State of Idaho's electrical permitting program (Division of Occupational and Professional Licenses, Electrical Bureau, formerly the Division of Building Safety), not the Twin Falls County Building Department. No county-specific or state-published EV-charger/EVSE line item, distinct fee, or dedicated application was found; EVSE circuits are permitted as ordinary electrical work under the state's standard Electrical Permit Application.

Tips

  • Do not contact the Twin Falls County Building Department for an EV charger electrical permit -- electrical work in unincorporated Twin Falls County is permitted directly through the State of Idaho (DOPL Electrical Bureau, 1-800-955-3044 or dopl.idaho.gov), the same as the county's electrical component of solar PV installations.
  • The statewide Existing Dwelling Unit Permit fee ($65 per inspection, IDAPA 24.39.10 Section 500.02.a.ii) covers a residential EVSE circuit added to an existing home; contractor-installed EVSE tied to new construction/commercial work instead falls under the Other Installations tiered fee ($60 + 2% of wiring cost up to $10,000, per IDAPA 24.39.10 Section 500.02.b).
