Commercial electrical service covers the wiring, power and lighting that keep a business running: tenant improvements, 3 phase equipment, panel and service upgrades, code corrections, lighting and repairs. In Federal Way, that work comes with its own permit and inspection process through the City of Federal Way, plus Washington energy code rules for lighting. Electrician Federal Way connects property owners, managers and business owners with licensed local commercial electricians. Call (253) 555-0100 and tell us about your space.
Commercial Electrical Services Businesses Ask For

Where Federal Way Businesses Are
Federal Way sits on I-5 between Seattle and Tacoma, and its commercial property ranges from older strip centers to newer mixed use and office buildings. Each area tends to bring its own kind of electrical work.
- City Center and The Commons area
- S 320th St corridor
- Pacific Hwy S (SR 99)
- S 348th St retail area
- Enchanted Pkwy S
- West Campus and former Weyerhaeuser campus area
- Town Square Park area
- SR 18 and I-5 interchange area
Along Pacific Hwy S and in older centers, electricians often find aging panels, past tenant add-ons and lighting that no longer meets energy code once a space is remodeled. Offices and medical suites near City Center tend to need tenant improvement work and data circuits, while restaurants throughout the city need kitchen equipment circuits and exhaust hood power.
Tenant Improvements in Federal Way: How the Electrical Side Works
A tenant improvement (TI) is any build-out or remodel of a commercial space for a tenant. According to the City of Federal Way’s TI checklist, separate permits are required for electrical, fire alarm and fire suppression work, so the electrical permit is its own application alongside the building permit. The checklist also calls for Non-Residential Energy Code compliance forms for lighting and mechanical work when they apply.
Scope and site visit
Your electrician reviews the lease plan or drawings, checks the existing panel and service, and confirms voltage and phase (for example 120/208 volt or 277/480 volt 3 phase).
Load calculation and layout
Equipment loads are added up to see whether the existing service can handle them, and circuits, panels and lighting are laid out.
Permit through the City of Federal Way
The electrical permit is applied for with the city, which handles electrical permits and inspections inside city limits instead of Washington L&I. Larger projects may need plan review.
Rough-in and inspection
Boxes, conduit and wiring go in before walls and ceilings are closed, and the city inspects the rough-in.
Finish, final inspection and handoff
Devices, fixtures and panels are finished, circuits are labeled, and the final inspection is passed so the space can move toward occupancy.
Talk with your landlord, general contractor and electrician early. Utility upgrades with Puget Sound Energy, lead times on switchgear and transformers, and inspection scheduling can all affect your opening date.

Single Phase vs 3 Phase Power
| Single phase | 3 phase | |
|---|---|---|
| Where you find it | Homes, small offices, some small retail | Most larger commercial buildings, restaurants, shops, warehouses |
| Common voltages | 120/240 volt | 120/208 volt or 277/480 volt |
| Good for | Lighting, outlets, small equipment | Motors, compressors, rooftop HVAC, commercial kitchens, large machines |
| What to check | Enough capacity for new loads | Equipment voltage matches the building, phase balance, available space in panels |
Before buying equipment for a new space, confirm the building’s voltage and phase with your electrician. A 480 volt machine will not simply plug into a 208 volt building, and adding a transformer or new service changes both cost and schedule.
Code, Licensing and Energy Rules
- Licensing. Washington requires electrical contractors to be licensed and electricians to be certified by the Department of Labor & Industries. You can check any contractor on the L&I website.
- Electrical code. Washington electrical rules are in WAC 296-46B, which adopts the National Electrical Code (NEC) with state amendments.
- Energy code. Commercial lighting work often needs Washington State Energy Code compliance, including lighting controls such as occupancy sensors and daylight controls.
- Emergency and exit lighting. Businesses need working exit signs and emergency lights, which are often checked during fire inspections.
- Working clearance. Panels need clear space in front of them. Storage stacked in front of an electrical room is a common inspection finding.
- GFCI protection. Commercial kitchens, restrooms, rooftops and outdoor areas have GFCI requirements.
Signs Your Business Needs an Electrician
- Breakers trip when equipment starts up
- Lights flicker or dim across the space
- Motors run hot or fail early
- Panels are full or hot to the touch
- Extension cords used as permanent power
- A correction notice from the fire marshal or inspector
- Exit or emergency lights fail their test
- New equipment is on order for your space
What Affects the Cost of Commercial Electrical Work
| Factor | Why it matters |
|---|---|
| Size and type of space | Square footage and use (office, retail, restaurant, medical) drive the amount of wiring and lighting. |
| Existing service capacity | If the service or panels are too small, upgrades or utility work may be needed. |
| Wiring method | Conduit, MC cable and open ceiling work take different amounts of time and material. |
| Equipment list | 3 phase equipment, kitchens and HVAC add dedicated circuits. |
| Permits and plan review | Larger or more complex projects take more design and paperwork. |
| Working hours | Work done after hours to keep a business open can change the price. |
| Material lead times | Switchgear, transformers and special fixtures can affect the schedule. |
Ask about phasing the work, scheduling shutdowns outside business hours and labeling every circuit when the job is done. A clear panel directory saves time on every future service call.
