Commercial Electrical for Working Properties & Businesses
Commercial electrical work has to fit around a business that is trying to stay open.

Work is scoped from drawings or a walkthrough, priced in writing, and scheduled around operating hours.

What Changes on an Occupied Property
The electrical is often the simple part. Access, timing and approvals decide whether the job goes well.
- —Work scheduled around business hours where the space cannot be taken offline during the day.
- —Notice, access and work areas planned in advance rather than negotiated on site.
- —Written scope suitable for owner, board or corporate approval before work starts.
- —Older buildings modified over decades, where circuits get traced instead of read off a schedule.
- —Circuits sized from equipment nameplates and coordinated with the equipment vendor when needed.
- —Permitted work carried through inspection, coordinated with the GC and landlord requirements.
Scope, access constraints and schedule are agreed in writing before mobilization.
On an occupied property, a wrong diagnosis costs more than hours
Downtime, tenant complaints and a second visit are the real costs. Approximately 20 years of field work is what keeps scope, access and schedule honest before anyone signs off.
Commercial proof means scope, challenge, solution and completion photos. These two completed projects are the closest match in scale and difficulty — multi-metered distribution, and concealed routing through finished masonry.

Two-unit infill, separately metered
- Property / project type
- Two-unit modern infill on a single urban lot
- Electrical challenge
- Two metered services and two inspection scopes on one schedule
- Scope of work
- Separate metering and panels per unit, parallel rough-in, recessed and linear lighting, kitchen and laundry circuits, device layout around full-height glazing
- Result
- Both units trimmed and passed on the same inspection cycle

Hacienda estate renovation
- Property / project type
- Hacienda-style estate — exposed timber ceilings, brick and plaster
- Electrical challenge
- Almost no stud cavity to conceal wiring in
- Scope of work
- Concealed routing through beams and masonry, sconce and vanity circuits, mini-split feeds, pool and spa circuits with bonding, panel upgrade, terrace and landscape lighting
- Result
- Finished rooms show fixtures only — no surface raceway
Commercial Questions
Can you work outside business hours?+
Scheduling around operating hours is normal on occupied properties, and it is agreed with the scope before mobilization.
Do you handle tenant improvements?+
Yes — lighting, equipment circuits, panel and distribution work, and buildout electrical coordinated with the GC and the landlord work letter.
Can you work from drawings?+
Yes. Send the drawings and the bid date and J.I.C. will confirm fit and availability before bidding.
What if the building has no panel schedule?+
That is common. Circuits get traced and the resulting schedule is documented so the next person is not starting over.
What size commercial work fits J.I.C. best?+
Troubleshooting, lighting, equipment circuits, tenant improvements, service and distribution work, and small commercial construction. Larger scopes are assessed case by case.
Can you provide a written scope for approval?+
Yes. Scope and pricing are provided in writing in a form suitable for owner or board approval.
