Electric Vehicle (EV) Charger / EVSE Permit (State of Idaho)
VerifiedThe City of Ketchum does not issue electrical permits — like all other electrical work, EV charger/EVSE circuit installation is permitted and inspected directly by the State of Idaho Division of Building Safety (DBS)/DOPL, confirmed on the City's own Inspections page ('All mechanical, electrical and plumbing inspections are handled by the State of Idaho.'). No dedicated EV charger/EVSE fee category exists in IDAPA 24.39.10 (Rules of the Idaho Electrical Board) — a new EV charger circuit added to an existing residence is billed under the flat $65 Existing Residential Dwelling Unit Permit fee, confirmed directly against DOPL's currently published electrical board rules (the same statewide schedule verified for Idaho City, Jerome, and Kellogg, ID in this same research pass). A grid-connected renewable-energy Plan Check Fee line exists on DOPL's older Homeowner Electrical Permit Application & Fee Worksheet, but it is scoped to solar/renewable generation interconnection, not EV charging load.

Requirements

- Idaho state law allows a homeowner to pull their own electrical permit for EV charger installation on their primary or secondary residence and associated outbuildings not used commercially or rented to a tenant

| Fee type | Amount | Notes |
|---|---|---|
| Existing Residential Dwelling Unit Permit | $65 per inspection | No distinct EV charger/EVSE fee line exists; a new EV charger circuit added to an existing residence is billed under this general existing-dwelling-unit fee. IDAPA 24.39.10, Rules of the Idaho Electrical Board, Section 050.02 (Residential Permits, Existing Residential Dwelling Unit) -- current rule text. Note: the City-linked DOPL 'Homeowner Electrical Permit Application & Fee Worksheet' (rev. 8/17/2022) still shows an older formula ('$65 plus $10 per additional branch circuit'); that per-circuit add-on was dropped in a subsequent DOPL rulemaking and does not appear in the current IDAPA 24.39.10 rule text, confirmed 2026-07-20 directly against DOPL's currently published Idaho Electrical Board rules PDF. Use the flat $65/inspection figure, not the stale worksheet's formula. |
| New Single Family Dwelling — up to 1,500 sq ft | $130 | Applies if the EV charger circuit is installed as part of new residential construction, billed under the same whole-house new-construction fee tier as other electrical work. IDAPA 24.39.10, Section 050.01.a; confirmed 2026-07-20 against DOPL's current rules PDF -- matches the 2022 worksheet's figure, so this one remains current. |
