This article is for planning purposes only. Cost, timeline, permit, code, gas, grease trap, public health, and accessibility requirements vary by project scope, municipality, landlord, site condition, engineering, equipment list, and current trade and supplier availability. Confirm specific requirements with the municipality, architect, engineer, landlord, public health unit, fire reviewer, AGCO, registered or certified fuels contractor, electrical contractor, or other applicable authorities.
If you are about to interview general contractors for a restaurant build-out in Toronto or the GTA, the single most useful filter is the questions they ask back. A restaurant build-out contractor's worth is in the questions they ask before quoting, not the speed of the answer. A contractor who quotes a price after a fifteen-minute walkthrough is guessing; a contractor who comes back with a list of clarifying questions about your hood, your interceptor, your equipment list, and your lease work-letter scope is doing the work that protects you from change orders later. Use the ten questions, the line-item checklist, and the red-flag list below to vet your shortlist before you sign anything. These are general-market observations that vary by site, supplier, and trade availability — your final shortlist depends on the specific project in front of you.
If you would like a contractor to walk a unit with you and read the panel, the ceiling, and the work letter before you commit, Buildup Contracting does free pre-construction site walks across Toronto and the GTA.
A great office contractor can be the wrong fit for a restaurant. The reason is that restaurant tenant improvement involves a stack of trades that residential, retail, and even commercial-office contractors do not usually coordinate together on a regular basis:
None of those are line items on a typical office build. A contractor who has done a hundred office TIs but no restaurants is going to learn on your project — and you are going to pay the tuition through change orders.
The right question is not "have you built commercial spaces", it is "have you coordinated grease hoods, fresh-air systems, gas piping, and pre-opening health inspections on restaurant projects". You want a contractor whose answer is specific.
These are the ten questions experienced operators ask in a contractor interview. None of them have right or wrong answers in the abstract — what you are listening for is whether the contractor has actually thought about each one before, and whether the answer matches your project.
You want a yes with detail. "We've worked with [hood supplier] and [mechanical engineer] on hoods of this size" is a good answer. "We can sub that out" is a worse answer — it means trade coordination falls on you or your architect.
The interceptor is one of the most expensive plumbing items on the job, especially if the existing one is too small or in the wrong location. A contractor who quotes a restaurant build without confirming the interceptor situation has not actually scoped the job.
Most working restaurant general contractors are construction-only. Permit drawings come from your architect or a permit consultant; the contractor coordinates with that team but does not stamp the drawings. A contractor who claims they "pull permits for you" is either oversimplifying for the sales conversation or confused about what an architect actually owns. Either is a flag.
A restaurant has six to twelve trades on a small footprint. The order they show up in matters as much as the quality of the work. You want to hear about a written schedule, weekly trade meetings, and a single point of contact who is on site.
Landlords often deliver a base building that is short on capacity for a restaurant load. Who flags it? Who chases the landlord to fix it? Who absorbs the cost if the landlord refuses? A contractor with restaurant experience has seen this five times and has a process.
This is the most underrated question of the ten. Engineering coordination, sign permit and fabrication, equipment installation, low-voltage cabling, security, audio-visual, the final cleaning — all of these get dropped from quotes that are trying to look low. Ask for the exclusions list in writing.
Restaurant projects almost always have a few change orders — menu tweaks, equipment substitutions, a hidden condition under the slab. The right answer involves a written change-order process with prices and schedule impact agreed before the work happens, not after.
You should hear: building, electrical (ESA), gas (TSSA), plumbing, fire, and public health pre-opening. Bonus points if the contractor explains the order they happen in and which ones gate which. We've broken down the Ontario restaurant permits picture for operators who want a longer view.
This is gold when the answer is yes. Plaza and mall landlords have idiosyncratic work letters, hoarding rules, and after-hours restrictions. A contractor who has run a job in the same plaza already knows the property manager, the loading dock rules, and the on-site quirks.
You want a weekly progress report at minimum, a single point of contact, and a clear escalation path if something goes wrong. "We'll be in touch" is not an answer; "we send a Friday update with photos and the next-week schedule" is.
A real restaurant build-out quote is not one number. It is a line-item breakdown that mirrors the trades on the project. If a contractor's quote does not contain most of the items below, ask why before you sign.
A quote that breaks these out lets you compare contractors apples to apples. A single-page total with no breakdown forces you to take the number on faith.
These are the patterns that experienced operators have learned to walk away from. None of them are automatic disqualifications on their own — but two or three together usually means the contractor is either inexperienced with restaurants or pricing the job to win, not to deliver it.
We are a restaurant-focused general contractor. So you can compare us against your other shortlist contractors with the same vetting questions, here is what we actually do and do not do.
We have published our broader process on the project experience page and our FAQ for the questions we hear most often.
Use this as a scoring sheet during your contractor shortlist meetings. Mark each contractor against each item.
Score each contractor out of ten. Anything below seven is a flag worth following up on before you sign.
How many contractors should I get quotes from?
Three is the working standard. Two does not give you a triangulation point; four to five is more than the operator usually has time to vet thoroughly. Three contractors with comparable scopes give you the spread.
Should I take the cheapest quote?
Almost never. The cheapest quote is usually cheapest because it has the least scope. Read the exclusions list against the other quotes — if the cheap quote is missing the hood, the interceptor, or the engineering coordination, it is not actually cheaper, it is incomplete.
What references should I ask for?
Two restaurant operators the contractor has finished a project for in the last twelve months, ideally on the same kind of concept (QSR, full-service, hotpot, bubble tea). Ask each reference: did the project hit the budget within ten percent, did it hit the schedule within two weeks, and what would they do differently next time.
Does Buildup pull my permits?
No — Buildup is a construction-only general contractor. Your architect or permit consultant submits the permit drawings; we coordinate with that team and run the construction once the permit is issued. We have written more on this in our restaurant permits Toronto guide.
What is a typical deposit on a restaurant build-out?
Industry-typical maximum is 10–15 percent of the contract value at signing, with progress draws against milestones. Anything significantly higher is worth questioning. The deposit is for material procurement and mobilization — it is not the contractor's profit upfront.
Is the lowest construction window the best?
Not always. A contractor offering a four-week construction window for a full-service casual restaurant is either skipping coordination steps or using a number to win the job. Realistic windows are 6–8 weeks for QSR refreshes and 8–12 weeks for full-service casual; the longer window usually reflects the actual time to coordinate trades and inspections cleanly.
What if my landlord recommends a contractor?
Landlord-recommended contractors are often genuinely good — they know the building. But the relationship can also create a soft conflict during deficiency disputes ("the contractor will not press the landlord because the landlord is the bigger client"). Take the recommendation seriously, but vet the contractor on the same checklist as everyone else.
Should I sign a lump-sum or cost-plus contract?
Lump-sum is the standard for most restaurant fit-outs of known scope. Cost-plus tends to apply on projects with unknown structural conditions or heavy customization where a lump-sum forces the contractor to pad the number. For most plaza and mall restaurant TIs, lump-sum with a written change-order process is the cleaner deal for the operator.
