Installing a home EV charger in Benton County follows Washington electrical code: a Level 2, 240-volt charger needs a state L&I electrical permit and inspection. New commercial and multifamily projects must include EV-ready parking under the state building code.
Benton County residents installing a Level 2 (240-volt) home charger need an electrical permit through Washington Labor & Industries, which inspects electrical work in the county, plus adequate panel capacity. A Level 1 cord-and-plug charger on an existing outlet needs no permit. Washington's building and energy codes require a share of EV-ready or EV-capable parking spaces in new commercial, multifamily, and larger developments, with conduit and panel capacity roughed in. Public charging stations must meet ADA accessibility standards. Washington law also limits how much an HOA can restrict an owner's EV charger. Benton PUD and Benton REA may offer charging guidance or rebates.
Unpermitted electrical work: L&I stop-work order, required correction, penalties, and possible re-inspection fees. Non-compliant EV-ready construction must be corrected before occupancy.
