A restaurant is one of the most electrically demanding spaces you can build. It packs the power needs of a small factory, the lighting design of a boutique hotel, and a health-and-fire-code checklist all into a few thousand square feet — on a schedule where every day past opening is money lost. We've wired Greek restaurants, specialty coffee bars, and even an indoor mushroom farm supplying Michelin kitchens, so here's the honest breakdown of what the work involves.
1. Kitchen power is the heavy lift
Commercial kitchen equipment — ranges, ovens, fryers, walk-in coolers, dishwashers, hood exhaust — is a wall of dedicated high-amp circuits, much of it 208V or 3-phase. The build starts with a real load calculation against the building's service, because the honest answer is sometimes "the existing service can't carry this menu." Catching that on day one instead of during inspection is the difference between opening on time and not.
2. Hood, exhaust, and make-up air coordination
The kitchen hood isn't just an electrical connection — it ties fire suppression, exhaust fans, and make-up air together, and it has to interlock correctly to pass inspection. On a build-out for an indoor grow facility (Four Star Mushrooms) we coordinated exhaust and make-up air units with the mechanical contractor and did the 3-phase load analysis for the utility — the same discipline a serious kitchen hood demands. Get the coordination wrong and the two trades finger-point while your opening date slips.
3. Lighting is the customer's first impression
Front-of-house lighting is where a restaurant's design lives or dies — layered ambient, accent, and task lighting on dimming controls that shift from brunch-bright to dinner-warm. At Avli on the Park, a Greek restaurant in Lakeshore East, the scope was bar and architectural lighting with dimming controls worked out alongside the lighting designer. At Allez Cafe and Brew Coffee Lab, cafe build-outs mean getting counter, display, and signage lighting exactly right because that's what the customer photographs. This is the part where an electrician who only does new-construction tract wiring will disappoint you.
4. The stuff nobody sees but inspectors check
- Emergency and exit lighting — required, inspected, and easy to under-scope.
- GFCI protection everywhere near water — which in a kitchen is nearly everywhere.
- Fire-alarm coordination — tie-ins and device placement that have to satisfy the fire prevention bureau.
- Dedicated circuits for POS, refrigeration, and IT — you do not want the walk-in and the point-of-sale sharing a breaker.
- Panel labeling and clearances — the boring items that fail a rushed job at final inspection.
5. The build-out lives and dies on coordination
Electrical is one trade among many — GC, plumber, mechanical, low-voltage, equipment vendors — all working a tight sequence in a small space. The electrician who shows up when the schedule says, sequences rough-in around the other trades, and doesn't hold up the drywall is worth more than one who's a few dollars cheaper per hour. Most of our restaurant work comes through general contractors precisely because we don't have to be chased. If you're a GC, here's how we work with builders.
6. It doesn't end at opening
Kitchens are brutal on electrical systems — heat, grease, moisture, and equipment that runs 16 hours a day. The relationships that work are the ones where the same crew that built it out also handles service calls when a circuit trips mid-dinner-rush. We do ongoing service for the restaurants we build, which means when something fails at 7pm on a Friday, you're calling someone who already knows your panel.
