Commercial electrical work runs on schedule and code. General contractors need a subcontractor who shows up, wires it right, passes inspection, and doesn’t hold up the trades behind them. Z&J subcontracts commercial electrical across the DFW metroplex — tenant finish-outs, retail, restaurants, offices, and light commercial — with the reliability and documentation that commercial projects demand.
We bring the same precision we apply to high-end residential lighting to commercial spaces, where lighting quality increasingly drives how a brand and an environment are perceived. The difference between a flat fluorescent box and a well-lit retail or restaurant space is real money in foot traffic and dwell time.
Tenant finish-outs and fit-outs
Tenant improvement and finish-out work is the core of commercial electrical: taking a shell or a previous tenant’s space and wiring it for a new use. We handle panel and circuit work, lighting, power and data provisions, and the controls and life-safety systems a commercial space requires, all coordinated to the architect’s and the GC’s plans.
We read commercial drawings, pull permits where needed, and execute to the jurisdiction’s commercial code — which differs meaningfully from residential — so the job sails through inspection.
Commercial lighting and controls
Commercial lighting carries both a design and a compliance burden. We install layered lighting that makes retail merchandise, restaurant interiors, and office environments look their best, and we implement the energy-code-required controls — occupancy sensing, daylight harvesting, and automatic shutoff — that commercial jurisdictions now mandate.
Getting both right means a space that performs commercially and passes the energy-code inspection, without the value-engineered, lifeless lighting that makes so many commercial interiors feel cheap.
Schedule, documentation, and reliability
On commercial work, reliability is the product. We integrate into the GC’s schedule, communicate proactively, document our work, and hit our milestones so the other trades and the certificate of occupancy stay on track. Delays cascade on commercial projects, and we build our reputation on not being the cause of them.
From rough through trim and final inspection, we keep the paperwork and the workmanship at the standard commercial GCs and building departments expect.

Frequently asked questions
What size commercial projects do you take?
We focus on tenant finish-outs and light-to-mid commercial — retail, restaurants, offices, and similar fit-outs across DFW — where our blend of electrical reliability and lighting quality is a real advantage.
Do you handle the energy-code lighting controls?
Yes. Commercial jurisdictions require controls like occupancy sensing, daylight harvesting, and automatic shutoff. We design and install them to pass the energy-code inspection.
Can GCs count on you to hold the schedule?
That’s the point of hiring us. We integrate into your schedule, communicate proactively, and hit our milestones so we’re never the trade holding up the certificate of occupancy.
