EV Charger / EVSE Electrical Permit in Unincorporated Ada County, Idaho

Unincorporated Ada County requires an ev charger / evse electrical permit for: Electrical permit required for EVSE circuit/branch-circuit and charger installation — issued by Idaho DOPL, not Ada County, since Ada County Development Services issues no electrical permits; Homeowners performing electrical work on their own primary/secondary residence may pull a Homeowner Electrical Permit directly from DOPL; otherwise a licensed Idaho electrical contractor must pull the permit; Residential EVSE added to an existing dwelling is billed under DOPL's 'Existing Dwelling Unit' fee (per inspection) — there is no separate EV-charger fee category in the DOPL fee rule; Commercial/multi-family EVSE installations are billed under DOPL's wiring-cost-based commercial/industrial fee formula (percentage of total wiring cost, tiered by valuation); No county building permit is required for a standalone EVSE circuit unless it is paired with structural work (e.g., a new carport/canopy), in which case a separate Ada County building permit applies to that structural scope. If your project isn't listed, confirm with Ada County Development Services — Building Division at 208-287-7900 before starting work.

There is no distinct EV-charger fee category. A residential EVSE circuit added to an existing home is billed at DOPL's flat $65 'Existing Dwelling Unit' per-inspection rate. Commercial installations use DOPL's wiring-cost-based formula: $60 + 2% of wiring cost up to $10,000, $260 + 1% of the amount over $10,000 up to $100,000, or $1,160 + 0.5% of the amount over $100,000.
