Restaurant and Cafe Renovation Contractors in Toronto and the GTA

A restaurant renovation is not a fit-out with a kitchen bolted on. It is a mechanical and public-health project wearing a design front. The exhaust hood, the make-up air, the grease interlocking, the washroom count, the accessible path and the seating capacity all talk to each other, and get one wrong and the whole layout moves. Deomax renovates restaurants and cafes across Toronto and the GTA, coordinating the trades, the drawings and the approvals on one contract.

What a restaurant or cafe renovation covers

• Front of house. Seating layout and capacity, bar and service counter, millwork, lighting, acoustics, flooring, and the accessible route from the entrance through to the washroom.
• Back of house. Kitchen line, prep and dish areas, walk-in and dry storage, staff areas, and the finishes that survive being cleaned every night.
• Mechanical and electrical. Kitchen exhaust and make-up air, HVAC balance so the dining room is not fighting the hood, gas and electrical capacity for the equipment schedule, and the panel upgrade if the capacity is not there.
• Plumbing. Grease interceptor, floor drains and slope, hand sinks where public health requires them, and the mop sink nobody remembers until inspection.
• Washrooms and accessibility. Fixture count against occupancy, barrier-free washroom, door widths, thresholds and clearances.
• Finishes that pass. Washable, non-porous surfaces in food areas, coved flooring, and sealed junctions.

The part that decides the schedule

Restaurants live and die on opening dates, and the two things that move them are approvals and equipment lead times, not construction. Build the schedule backwards from those:

• Get the equipment schedule locked early. Every mechanical, electrical and plumbing decision hangs off it. Changing a piece of equipment after rough-in is the expensive change order.
• Landlord approval runs in parallel with the permit. In a leased unit the landlord’s approval of drawings, plus any base-building work they owe you, is a second queue running alongside the municipal one.
• Health approval is a separate track. Food premises are reviewed by the local public health unit. That review is not the building permit and it does not run on the same clock.
• Phasing for a trading restaurant. Where a renovation happens around an operating business, we work in zones with hard hoarding and dust control, and take the disruptive work into closed hours.

Permit requirements are set by your municipality and food-premises requirements by your public health unit, and both change. We confirm the position for your address and your use before design starts rather than after. See our permits and process page for how that runs.

Frequently Asked Questions

What does a restaurant renovation involve?
It is a mechanical and public-health project as much as a design one. The kitchen exhaust hood, make-up air, grease interceptor, floor drains, washroom fixture count, accessible path and seating capacity all depend on each other, so changing one usually moves the layout.

Do I need a permit to renovate a restaurant?
Almost always, and there are usually two separate tracks. The municipal building permit covers the construction, and food premises are reviewed by the local public health unit on their own timeline. In a leased unit the landlord’s approval of drawings is a third queue. We confirm all three before design.

Can I stay open during a restaurant renovation?
Sometimes, depending on scope. Where it is possible we work in zones behind hard hoarding with dust control and take the disruptive work into closed hours. A full kitchen replacement normally needs a closure, and it is better to plan one short closure than a long half-open period.

What controls the opening date?
Approvals and equipment lead times, not construction. Lock the equipment schedule early, because every mechanical, electrical and plumbing decision hangs off it, and a change after rough-in is the expensive one.

What we can show you is the trade work underneath it, and there is plenty of it in our project gallery: commercial washrooms, commercial kitchens, partition and demising walls, structural repairs, flooring and corridor finishes. Ask for sector references at the site visit and we will tell you straight what we have and have not done.
