Commercial Electrician in Seattle, WA

Konsker Electric handles commercial electrical for Seattle businesses start to finish: tenant improvement and buildout wiring, LED retrofits with the controls the Seattle Energy Code requires, service and panel work across 120/208V and 277/480V up to 600V, standby generators, and documented code compliance inspections. Seattle is the one part of our service area where the permit runs through Seattle DCI and the utility is Seattle City Light, so we pull the Seattle DCI electrical permit, coordinate the disconnect and reconnect with Seattle City Light when the job touches the service, and give you a flat-rate quote in writing before any work begins. Licensed, bonded, and insured for 20+ years. Call (206) 260-1981.

Tenant Improvement Electrical Through Seattle DCI

A Seattle tenant improvement runs on two permits, and confusing them is where buildouts stall. The electrical permit is separate from the general contractor's building permit and, per Washington rules, has to be pulled by the licensed electrical contractor, not the GC. Inside Seattle city limits that electrical permit goes through Seattle DCI, not Washington State L&I, and the city enforces its own amendments on top of the 2023 NEC. We meter the existing service, size the panel and feeders for the new tenant loads Downtown, in SODO, along Ballard Avenue, or on a Capitol Hill mixed-use floor, and sequence the rough-in around framing so the electrical is not the item holding up occupancy. See our commercial construction and tenant improvement service for the full head-term scope.

LED Retrofits and Service Work to 600V

Commercial LED retrofits are estimate-driven, not flat-priced, because the honest number depends on fixture count, whether you are relamping troffers or swapping housings, and whether you are adding the occupancy and daylight controls the Seattle Energy Code requires. We flag any Seattle City Light commercial lighting rebate the retrofit qualifies for, and we handle service and panelboard work across 120/208V and 277/480V three-phase systems up to 600 volts. The same crew covers our commercial maintenance and LED upgrades.

Standby Generators and Seattle City Light Coordination

For a commercial standby generator, we size the unit to the standby load, install a listed automatic or manual transfer switch, and coordinate the interconnection with Seattle City Light inside the city so critical loads at a medical office, grocery, or data closet stay up through the wind-driven outages that hit the Puget Sound lowlands every winter. When a buildout upsizes the service, we book the City Light disconnect and reconnect window on the front end so the meter work does not blindside your schedule.

Code Compliance and Permits, Handled

We document commercial code compliance against WAC 296-46B, the Seattle amendments, and the 2023 NEC, covering NEC 110.26 working clearances, panel labeling, grounding, and emergency and exit lighting, with a written report and photos within 24 hours. As a contractor licensed through Washington State L&I, we pull the Seattle DCI electrical permit, schedule the inspection, and book the City Light window for you.
