Commercial Office & Tenant Improvement Electrical
Corporate headquarters and office interiors get built on tight schedules, often inside occupied buildings, with no tolerance for disruption to the tenants next door or the base-building systems overhead. H&M Electric delivers commercial office and tenant-improvement electrical across Seattle, Bellevue, and the greater Puget Sound region — coordinated, on time, and unobtrusive.
Tenant improvements delivered on the schedule that matters
A tenant-improvement project lives and dies by its schedule. A signed lease sets a move-in date, and every trade is measured against it. H&M staffs and sequences office fit-outs to hit those dates — power and lighting for open offices, conference and huddle rooms, cafés and reception, plus the branch circuits, floor boxes, and low-voltage pathways that a modern workplace runs on.
We plan the electrical scope against the architecture and the furniture layout early, so that whip locations, floor boxes, and device placement are right the first time and not reworked after the millwork lands. On fast-track interiors, that coordination is the difference between an on-time turnover and a scramble at the end.
H&M has delivered high-profile corporate interiors in the region, and the discipline is the same whether the space is a floor or a campus: build to the drawings, coordinate relentlessly, and protect the schedule the tenant is counting on.
Base-building coordination and occupied-building fit-outs
Tenant work does not happen in isolation. It ties into base-building electrical — the risers, house panels, and metering that serve the whole property — and those tie-ins have to be coordinated with the building's engineer and its other tenants. H&M plans panel space, feeder capacity, and points of connection so a fit-out integrates cleanly with the base building rather than fighting it.
When the building is occupied, coordination becomes choreography. Deliveries, noisy work, and any shutdown of shared systems have to be scheduled around the businesses already operating in the building. We work with property managers to time disruptive activities for off-hours, protect common areas and occupied floors, and keep the building running normally while we build out the new space.
This is where a contractor's professionalism shows. A clean, well-communicated fit-out protects the owner's relationship with every other tenant in the building, and we treat that as part of our scope.
Lighting and lighting controls
Lighting is where an office project is most visible and most scrutinized. H&M installs and commissions modern lighting and lighting-control systems — daylight harvesting, occupancy sensing, dimming, and zoned scene control — that meet Washington's energy-code requirements while giving occupants comfortable, tunable spaces.
Controls are only as good as their commissioning. We program and verify zones, sensors, and schedules so the system behaves the way the design intended on day one, rather than becoming a facilities headache after move-in. Proper commissioning is also what turns an energy-code obligation into real, documented performance.
The payoff is a workplace that looks the way the architect intended and performs the way the owner is paying for.

Frequently asked
Questions buyers ask us
What is tenant improvement electrical work?
Tenant improvement (TI) electrical work is the power, lighting, and low-voltage scope that fits out a leased space for a specific tenant — open offices, conference rooms, break areas, and reception — including branch circuits, floor boxes, and lighting controls, tied into the building's existing base-building electrical.
Can electrical work be done in an occupied office building?
Yes. Most office fit-outs happen in occupied buildings. H&M coordinates with property management to schedule noisy or disruptive work and any shutdown of shared systems for off-hours, protects common areas and occupied floors, and keeps the building operating normally while the new space is built out.
How does H&M coordinate a fit-out with base-building systems?
H&M plans panel space, feeder capacity, and points of connection early and coordinates them with the building engineer and existing tenants, so a tenant fit-out integrates cleanly with the base-building risers, house panels, and metering rather than conflicting with them.
Does H&M install and commission lighting controls?
Yes. H&M installs and commissions lighting-control systems including daylight harvesting, occupancy sensing, and dimming, programming and verifying zones and schedules so the system meets Washington energy code and performs as designed from the first day of occupancy.
What areas does H&M serve for commercial office projects?
H&M serves the greater Puget Sound region with a core market in Snohomish and King counties, including Seattle and Bellevue, and works throughout Washington on commercial office and tenant-improvement projects.
