Plan Your Kitchen Layout, Workflow and Utilities
A kitchen works when food, people and dishes move in a logical order and the building can supply what the equipment needs. Both are far cheaper to settle on paper than after construction starts.
Use the Utilities Checklist Builder to see what your equipment asks of the building, then use the guide to plan the layout, ventilation and health review around it.
Utilities Checklist Builder: What Does Your Equipment Ask of the Building?
Tick the equipment you expect to install. You get a list of what to confirm, who confirms it, and the layout type that suits your space.
Plan the Flow First, Then the Equipment
Start with how food moves: receiving, storage, preparation, cooking, holding or service, and warewashing. Then match the layout to how you serve customers, and check each piece of equipment against gas, electrical, water, drain and ventilation capacity.
Who This Guide Is For
Plan the Flow of Food
Food should move in one direction without backtracking.
A good layout follows the order of work, keeps clean and soiled items on separate paths, and keeps raw preparation away from ready-to-eat food. Draw the path first, then place equipment along it.
Walk the sketch as a cook would
- Receiving to storage without crossing the prep area.
- Storage close to the prep that uses it.
- Cooking under ventilation, close to service.
- One warewashing path, separate from the food.
| Stage | What it needs | Common problem |
|---|---|---|
| Receiving | A clear route from the delivery door and space to check and sort | Deliveries pass through the prep area |
| Storage | Dry, refrigerated and frozen storage close to receiving and to prep | Cold storage at the far end of the kitchen |
| Preparation | Prep surfaces, sinks and refrigeration within easy reach of each other | Prep and cooking share one bench |
| Cooking | The line under the hood, with gas and electrical service | Equipment chosen before the hood is sized |
| Holding and service | Hot and cold holding, plating or the counter handoff | Pass too small for the rush |
| Warewashing | A separate path where soiled dishes enter and clean dishes leave | Dish return crosses the cooking line |
Choosing a Layout Type
Match the layout to the room, then to the menu.
Most commercial kitchens use one of five arrangements, or a mix. The room you have usually narrows the choice before the menu does.
Rules of thumb
- Narrow rooms suit a galley or a line.
- Large square rooms suit an island or zones.
- Open kitchens add noise, odour and cross-contamination care.
| Layout | Best suited to | Watch for |
|---|---|---|
| Assembly line | High-volume, limited-menu operations such as cafeterias and pizza shops | Less flexible if the menu changes a lot |
| Galley | Limited square footage, smaller menus, low to mid volume | Cramped at heavy volume, with two people sharing a narrow aisle |
| Zone | Medium-sized kitchens with a logical sequence of stations | Needs enough floor space for an open centre |
| Island | Large, roughly square kitchens | Needs generous open floor space; ventilation over the island is a bigger project |
| Open kitchen | Concepts where customers see the cooking | More noise and odour, and more care separating raw and ready-to-eat food |
How Your Service Model Changes the Plan
Plan for every way you will serve, not just the main one.
How you serve customers affects the counter, the storage and the workflow behind it. Also decide how much space goes to the front of the house and how much to the back. Customer-facing space earns revenue, but a back-of-house that is too small slows everything down.
| Service model | Plan for |
|---|---|
| Counter service | Counter footprint, handoff, queuing, undercounter storage for high-frequency items |
| Takeout and pickup | A pickup point away from the order line, packaging storage, holding for ready orders |
| Grab-and-go | Refrigerated display or storage at the front, easy restocking from the back |
| Dine-in | The route between the kitchen, the dining room and the dish area |
| Delivery and catering | Packaging, holding and transport, and staging space near the door |
| Banquet and event service | High-capacity holding, transport and a path for service peaks |
Plan Your Utilities
Check every spec sheet against what the space can supply, before you order.
Each piece of equipment lists what it needs: fuel, voltage and phase, water, drain and ventilation. Add them up for the whole line, because a service that suits one unit can fail when everything runs together.
Look for the certification marks your authority accepts, such as CSA or cULus, on gas and electrical equipment.
Who confirms what
- Gas: licensed gas fitter and the gas utility.
- Electrical: licensed electrician.
- Water and drains: licensed plumber.
- Ventilation: mechanical contractor and local authorities.
| Utility | What to confirm | Who confirms |
|---|---|---|
| Gas | Natural gas or propane, total connected load, pipe size and meter capacity, shut-off and connector for each unit. Adding load later can mean utility upgrades with long lead times. | Licensed gas fitter and gas utility. In Ontario, fuel safety is administered by TSSA; other provinces have their own authority. |
| Electrical | Voltage, phase, amperage and circuits for every plug-in or hard-wired item. A panel sized for the last tenant may not suit your concept. | Licensed electrician |
| Water | Hot and cold supply, pressure, and filtration for ice makers, beverage equipment and steamers | Licensed plumber |
| Drains | Floor drains, indirect waste connections for equipment, and any grease interceptor your municipality requires | Plumber and local authority |
| Ventilation | Hood coverage over cooking equipment, fire suppression, and make-up air to replace what the hood removes | Mechanical contractor, building and fire authorities |
| Refrigeration | Space around air-cooled units for airflow, electrical circuits, and where the heat goes | Refrigeration contractor and electrician |
Standards that commonly apply in Canada include the CSA B149.1 Natural Gas and Propane Installation Code for gas, and the Canadian Electrical Code (CSA C22.1) for electrical work. Your provincial rules and local authority decide what applies to your building.
Ventilation and Make-Up Air
The hood is a system, not a product. It only works if the building replaces the air it removes.
An exhaust hood pulls air out of the kitchen, and the building has to bring the same air back in. Without enough make-up air the hood cannot perform as designed, and the kitchen can feel hot, smoky and hard to work in. Coordinate make-up air with the hood and control it to run together.
Rules differ between municipalities. As one Ontario example, the City of Oshawa's published requirements for commercial cooking equipment refer to the NFPA 96 standard through the Ontario Building Code. They describe approved fire extinguishing equipment protecting hoods and ducts, and fuel or heat shut-off when it activates. They also set minimum clearances of 457 mm (18 in) to combustible material, 76 mm (3 in) to limited-combustible material and 0 mm to non-combustible material, with reduced clearances allowed for listed equipment.
Ask your contractor
- Does the hood cover every unit on the line, including any I add later?
- Is make-up air included, and how is it controlled?
- What clearances do my units and the wall behind them need?
- Who inspects the fire suppression before I open?
Hood coverage
Every piece of grease- or heat-producing equipment should sit under the hood. A fryer added later may fall outside what was designed.
Fire suppression
Systems protect the hood, duct and cooking surface, and are normally inspected by the fire authority before occupancy.
Make-up air
Outside air replaces what the hood exhausts. Poor balance shows up as heat, smoke and doors that are hard to open.
Clearances
Distances to walls and combustible materials come from the unit's manual and from local rules. Check both before you place equipment.
Submit Your Plans for Health Review
Ask your health unit what to submit before you build.
Most public health units review plans for new food premises and renovations. Requirements vary by province and by health unit, so treat this as a list of questions to bring to yours.
The following examples come from Ontario Regulation 493/17 (Food Premises). Other provinces have their own rules.
Bring to your health unit
- Scaled floor plans showing equipment, sinks and finishes.
- Where handwashing stations will be.
- How utensils and dishes will be washed and sanitized.
- Where food, chemicals and waste will be stored.
| Topic | What the regulation says (O. Reg. 493/17) |
|---|---|
| Handwashing | Requires an adequate number of handwashing stations. A handwashing station means a hand basin with hot and cold running water close to a soap dispenser and either a mechanical hand dryer or a single-service towel dispenser. |
| Utensil washing | A three-compartment sink, or mechanical equipment. A mechanical dishwasher's wash water is not lower than 60°C or higher than 71°C, and the sanitizing rinse is at least 82°C for at least 10 seconds, or uses a chemical solution. |
| Water | Potable water adequate for the operation, with hot and cold running water under pressure where food is prepared. |
| Floors | Tight, smooth and non-absorbent in food preparation areas. |
| Ventilation | The system must ensure the elimination of odours, fumes, vapours, smoke and excessive heat. |
| Temperature | Potentially hazardous food must be kept at 4°C or colder or 60°C or hotter, with limited exceptions such as up to two hours during preparation. |

Common Planning Mistakes
Most of these are cheap to fix on paper and expensive to fix after construction.
Choosing equipment before the building
The space decides what you can install. Check gas, electrical, water, drains and ventilation first.
Trusting the last tenant's setup
A hood, panel or gas supply sized for one concept may not suit another.
Adding a fryer late
It can force changes to the hood, make-up air and gas supply.
Running the hood without make-up air
The hood cannot do its job without replacement air.
Crossing food and dish paths
Soiled dishes should never share a route with food.
Skipping the plan review
Changes after construction cost far more than changes on paper.
Forgetting delivery access
Doors, lifts and turns matter on the day a large unit arrives.
Leaving no room to grow
Leave space and utility capacity for one more unit.

Frequently Asked Questions
Short answers to what new operators ask most.
Do I need an architect or kitchen designer?
For anything beyond a very simple kitchen, usually yes. Your health unit and building authority will want scaled plans, and a specialist can coordinate equipment, layout and utilities together. Russell Hendrix Design/Build can support the full kitchen.
When should I submit plans to public health?
Before construction or renovation begins. Ask your local health unit what to include and how long review takes.
Can I choose equipment before I choose a space?
You can plan categories and capacity, but check every item against the space before you buy. The building decides what you can install.
Does a small kitchen need a different layout?
Often a galley or compact line works best, with equipment kept on the countertop or under it where possible.
What if I want to add a fryer later?
Plan for it now if it is likely. Ventilation, make-up air and gas supply are much easier to size up front than to change later.
Do all cooking appliances need a hood?
Not necessarily. It depends on the appliance, its certification, and your local building and fire rules. Ask your ventilation contractor and your authority before you order.
When to Involve a Specialist
The checklist finds the questions. A specialist helps answer them with your plans in front of them.
Equipment, layout and utilities interact. Changing one often changes the others, and it is cheaper to resolve that before drawings are final.
Bring Sales or Design/Build in when
- You have a space but no layout yet.
- Gas, electrical or ventilation capacity is uncertain.
- The line includes more than one grease-producing appliance.
- You want one team to plan equipment and install it.
Plan the Building, Then Buy the Equipment
The strongest kitchens connect the layout, the building's utilities and the equipment before any purchase is final.
