Permits & inspections
Electrical work in Washington requires a permit and inspection, with exceptions at WAC 296-46B-901 (verified firsthand on the L&I permits page). Permits are purchased by the electrical contractor or by the property owner/homeowner doing the work. If the jobsite is in a city that does its own permits and inspections, or in Tacoma Power service area, the permit and inspection come from that jurisdiction; all other jobsites are permitted and inspected by L&I. L&I states it inspects electrical work using the 2023 NEC.
