How long does it take to plan a restaurant build-out in Ontario?
Planning a restaurant build-out is a sequence of ordered decisions with explicit stop points. Follow these steps to protect your schedule, keep costs visible, and give contractors enough information to price accurately. This guide is focused for owners and operators in the GTA and Ontario, but the process applies broadly. Where municipal timing matters, cited resources explain what to expect.
Step 1: Define your concept, budget and hard dates
Write a one-page brief that answers three core questions: what is the concept, when must you open, and how much capital is available. The brief should capture service style, target covers, expected peak hours, and any deal-breakers such as late-night operation, rooftop seating, or unique equipment needs. Defining concept and capacity up front keeps layout, ventilation and seating density decisions consistent with your business plan and permits.
Early direction helps your designer and contractor avoid rework and keeps the budget meaningful. For a broader view of how concept informs team and cost decisions, consult industry guidance on restaurant construction and design.

Step 2: Confirm the site, lease terms and landlord approvals before scoping
Pause before you commission drawings and confirm the lease and landlord permissions in writing. Obtain explicit approval for items that affect scope: alterations to mechanical systems, kitchen exhaust and grease trap installation, hours of operation, signage, and loading or parking arrangements. Landlord limitations are a frequent cause of late scope changes and cost growth, so secure approvals before instructing designers or contractors to price demolition, ductwork or structural work.
For Ontario projects, confirm whether tenant improvements must be returned to base building condition at lease end and who is responsible for utility upgrades. Municipal reviewers expect a scope that matches the lease when assessing permit submissions.

Step 3: Create a floor plan and a submission-ready drawing package
Produce plans that separate front of house and back of house, show circulation and egress, and place major kitchen equipment in a functional workflow. A useful drawing package contains:
- Floor plan with fixed seating, exit paths and aisle widths
- Kitchen plan showing equipment layout, service zones and ventilation hoods
- Plumbing and electrical risers for major appliances and washrooms
- Mechanical notes for HVAC and exhaust ducts
- Finish schedule and lighting concept for FOH and BOH
Detailed plans reduce guesswork and let trades price specific work instead of adding conservative allowances. For advice on balancing efficiency, customer experience and compliance in a floor plan, see the layout guidance.

Step 4: Permits and municipal reviews: stop here until approvals are clear
Permits determine when physical work can begin. In Ontario and across the GTA, restaurant tenant improvement plan reviews require a complete submission package. Expect municipal plan review time to be part of your schedule. Many GTA municipalities process restaurant TI plan review packages in roughly four to seven weeks for a clean submission, though additional submission rounds will extend that window. Treat permit review as a formal stop point before demolition or major mechanical work.

Required approvals commonly include building permits, fire department sign-off for egress and suppression, public health approvals for food handling, and sometimes zoning or committee of adjustment approvals if the use or hours change. Use your drawing package to determine which reviewers must sign off before construction starts.
Step 5: Prepare a detailed scope: what to bring so contractors can give accurate quotes
Bring this packet to every contractor meeting. Deeroi Constructions asks clients for the address, scope and deadline to create accurate quotes and a coordinated plan; mirror that intake to avoid vague estimates. Include:
- The exact address and unit boundaries, with the lease pages that show allowed alterations
- Submission-ready drawings or concept sketches, existing site photos and MEP plans if available
- A short equipment list for the kitchen showing major items that need electrical, gas or plumbing hookups
- Target opening date or milestones and any critical lease dates
- High-level budget range and any items you will self-supply
- Photos or portfolio references demonstrating the finish level you expect
Providing these items reduces the guessing that drives contingency line items in bids. If you want a turnkey approach that bundles millwork, lighting and finishes, review contractor portfolios to confirm the match with your expectations.
Step 6: Choose and interview contractors: questions, decision criteria and warning signs
A useful filter when interviewing general contractors is the questions they ask back. A competent contractor will probe the project, not race to a price. Expect them to ask about lease restrictions, mechanical capacity, grease management, fire protection, utility metering, and whether the landlord requires after-hours work.
Questions a competent contractor should ask
- Can you share the lease clauses that affect alterations and hours?
- Do you have existing MEP drawings or service reports?
- What is your equipment list and who supplies the major appliances?
- What is your target opening date and required milestone dates?
- Are there landlord or building rules for noisy work or after-hours access?
Decision criteria and warning signs
- Prefer firms that provide a written scope tied to drawings, a clear schedule, and an allowances list for unspecified finishes.
- A fast fixed-price quote after a short walkthrough is a warning sign; that indicates guesswork rather than scoped pricing.
- Ask for a photo-rich portfolio of similar restaurant work to confirm finish quality, especially for millwork and bar counters.
- Confirm the contractor’s process for trade coordination and who will submit shop drawings to you and the municipality.

Step 7: Identify the trades, cost drivers and coordination priorities
Typical trades for a turnkey restaurant build-out include demolition, carpentry and millwork, mechanical and HVAC contractors for hoods and exhaust, plumbing for grease traps and fixtures, electrical for power and lighting, fire suppression installers, tile and waterproofing, and finish painters. Major cost drivers are mechanical upgrades, hood and exhaust installation, custom millwork, and any structural or storefront changes.
Sequence coordination this way to avoid rework: confirm permits and drawings, install or modify major mechanical systems and hoods, complete rough-ins for electrical and plumbing, then follow with millwork and finishes. Early coordination meetings with the kitchen equipment supplier prevent layout clashes and last-minute rerouting of services.

Step 8: Key milestones before construction and the next step to get a quote
Before you sign a construction contract, verify these milestones in order:
- Signed lease and written landlord approvals for tenant work
- Submission-ready drawings and consultant signoffs where required
- Permit submission and acceptance of the municipal plan review package
- Permit issuance, or a documented plan for phased work allowed before permit
- Contractor award with agreed scope, schedule and payment terms
- Shop drawing approvals and material lead-time confirmations
- Site mobilisation and trade scheduling
Next step: collect your address, scope and deadline and request a construction quote so a contractor can price to drawings and timelines. Deeroi Constructions accepts that intake and provides portfolio examples of complete restaurant build-outs to help owners compare finish levels before hiring.

Frequently asked questions
How long do restaurant permits and plan reviews typically take in the GTA?
Review times vary by municipality and by how complete the submission is. Many GTA cities process restaurant tenant improvement plan reviews in about four to seven weeks for a clean submission. Expect extra rounds to extend that time and build the review window into your schedule.
Example plan review guidance
What exact documents should I bring when I ask contractors for a build-out quote?
Bring the address and lease pages that limit alterations, existing MEP plans and photos, submission-ready floor plans or sketches, a kitchen equipment list, and your target opening date. Supplying these items reduces guesswork in bids and mirrors the intake construction firms use to price projects accurately.
Who is normally responsible for mechanical or ventilation upgrades during a tenant improvement?
Responsibility depends on the lease. Some landlords cover base building mechanical capacity upgrades, while tenant contracts often pay for tenant-specific hoods, ductwork and exhaust within the unit. Confirm responsibility in writing before pricing begins and include mechanical scope in your contractor packet. For regulatory and layout implications, review Ontario build-out guidance.
Ontario permits and ventilation considerations
How much contingency should I allow when budgeting for a restaurant build-out?
Contingency depends on site condition and the level of unknowns. Instead of a single fixed number, discuss specific risk items with your contractor and set a reserve sized to address mechanical surprises, concealed conditions, or bespoke millwork changes. A contractor experienced in restaurant work will help you size a contingency based on the actual scope.
Can I start fit-out work before municipal approvals are complete?
Starting work before permits are issued risks stop-work orders, fines, and rejected inspections. Some municipalities allow limited non-structural work or preparatory activities with written conditional permission. Treat permit issuance as a formal stop point unless you have explicit written approval from the building department to proceed with specific tasks.
Final checklist and next step
Transcribe this short checklist before your next contractor meeting: signed lease pages, address and unit plan, submission-ready drawings, equipment list, target opening date, and site photos. When you have those items, request a quote so a contractor can provide a scoped estimate and schedule.
