Do I need a permit for ev charger installation in Unincorporated Grant County?
Yes. In Washington, ev charger installation generally requires a permit, and Unincorporated Grant County is no exception.
A new 240-volt circuit, outlet, or hardwired charger needs an electrical work permit; only like-in-kind swaps such as one household appliance or a circuit breaker are permit-exempt Class A work (WAC 296-46B-901). L&I issues the permit and inspects unless the address is in a city with its own electrical program or in Tacoma Power's service area. An owner may wire their own residence without an electrical license (RCW 19.28.261), but must still buy the permit; a hired contractor must buy its own permit.
