A commercial kitchen build is a web of interlocking systems: exhaust hoods and make-up air, grease interceptors, fire suppression, and heavy plumbing, electrical, and refrigeration loads, all meeting health and safety requirements. Coordinating those systems with the front-of-house and the opening date is what makes a restaurant build work.
A Kitchen Is a System, Not Just a Room
From the dining room, a restaurant looks like design and hospitality. Behind the pass, it's engineering. A commercial kitchen ties together ventilation, fire protection, plumbing, electrical, refrigeration, and gas, all of which have to be sized to the menu and the equipment and signed off by the authorities having jurisdiction. Get one system wrong and it ripples through the rest.
Understanding how these pieces fit together is what keeps a restaurant build on track. Here's what goes into the back of house, and how it connects to the front.
Exhaust Hoods and Make-Up Air
The exhaust hood over the cooking line pulls heat, smoke, and grease-laden vapor out of the kitchen. But you can't just exhaust air without replacing it. Make-up air systems bring conditioned air back in to balance what the hoods remove, which keeps the kitchen comfortable, the doors easy to open, and the whole building's air pressure in balance. These two systems have to be designed together and sized to the cooking equipment beneath them.
Grease Handling and Fire Suppression
Cooking produces grease, and grease has to be managed at every stage. A grease interceptor keeps it out of the building's drains and the municipal system, and its size is driven by the kitchen's output. Above the line, a fire suppression system tied into the hood is required to protect the cooking equipment. Both are non-negotiable, inspected systems, and both need to be planned into the build from the start.
- Grease interceptor sized to the kitchen's volume and local requirements
- Hood-integrated fire suppression over the cooking line
- Coordination between suppression, gas shut-off, and the exhaust system
- Inspection and sign-off built into the schedule
Plumbing, Electrical, and Refrigeration Loads
Commercial kitchens carry heavy loads in every utility. Plumbing serves sinks, dishwashing, prep stations, and food-safety fixtures. Electrical has to support cooking equipment, refrigeration, and the exhaust and make-up air systems. Refrigeration, from walk-ins to line coolers, adds significant electrical and sometimes plumbing demand. Each of these is sized to the specific equipment plan, which is why the kitchen layout has to be settled early.
- Plumbing: Dish areas, prep sinks, hand-wash stations, and food-safety fixtures positioned to the workflow.
- Electrical: Capacity for cooking equipment, refrigeration, and mechanical systems, planned to the equipment schedule.
- Refrigeration: Walk-ins and coolers coordinated with electrical, drainage, and floor finishes.
Health, Safety, and the Authorities
A commercial kitchen has to satisfy health-authority and building requirements covering surfaces, drainage, hand-washing, ventilation, and food-safety separation. Finishes need to be cleanable and durable, floors need proper drainage and the right slip rating, and the layout has to support safe food flow. Planning these requirements in from the beginning, rather than reacting to them at inspection, keeps the project moving toward sign-off.
Where Front-of-House and Back-of-House Meet
The kitchen doesn't exist in isolation. The pass, the service stations, the bar, and the dining room all connect to the back of house, and the systems have to flow cleanly across that line. The same project that's building grease interceptors and hoods is also delivering the finishes, lighting, and atmosphere your guests experience. Coordinating both halves under one contractor keeps the technical and the hospitality sides of the build aligned.
That coordination is why a single point of contact matters so much on a restaurant. One team is managing the specialized food-service trades, the inspections, and the front-of-house finish, so the two sides come together on schedule rather than colliding at the end.
Planning Around Opening Day
Restaurants live and die by their opening. Staff are hired, inventory is ordered, and marketing is timed to a date, so the build has to be sequenced backward from it, with the long-lead equipment, the mechanical systems, and the inspection points all mapped against the calendar. While no responsible contractor guarantees a date before seeing the space, a clear plan tied to your opening lets you commit your staffing and launch with confidence.
If you're planning a restaurant or commercial kitchen, let's talk through your menu, your equipment, and your target opening, and map out what your build will take from back of house to front.
