If you’re dreaming of opening a restaurant in Ontario, you’re not alone. With a thriving culinary scene, a diverse population, and a steady demand for new dining experiences, Ontario is a hotbed for food entrepreneurs. But before you start designing menus or choosing furniture, there are key construction, design, and regulatory steps that can make or break your project.
As expert contractors in Ontario, Diamond Builders Group has worked with entrepreneurs across the province to bring their restaurant visions to life. Here’s what you need to know before you break ground.
1. Zoning & Permits: Your First Major Hurdle
The first step is making sure your chosen location is properly zoned for restaurant use. Zoning regulations vary between municipalities, and even between neighborhoods. You’ll need to:
- Check municipal zoning bylaws to confirm your space allows for commercial food service.
- Apply for change-of-use permits if you’re converting a residential or retail space.
- Secure a building permit for any construction or structural changes.
💡 Pro Tip: Partner with a contractor who understands Ontario’s zoning landscape and can work with local officials to fast-track approvals.
2. Health & Safety Regulations
Restaurants in Ontario are subject to strict health and safety codes. You’ll need to plan for:
- Commercial-grade ventilation systems
- Non-slip and easy-to-sanitize flooring
- Proper food storage areas (dry, refrigerated, and frozen)
- Accessible washrooms for staff and customers
Your contractor should collaborate with a health inspector from the design phase to avoid costly delays or rebuilds.
3. Design for Efficiency and Flow
Design isn’t just about aesthetics — it’s about workflow. An efficient kitchen layout can save thousands over time in labor costs and service speed.
Key considerations include:
- Back-of-house design: Prep area, cooking line, dishwashing, and dry storage should all follow a logical flow.
- Front-of-house: Tables, bar area, and waiting zones should allow for smooth circulation and comply with accessibility standards.
- Mechanical needs: Grease traps, gas lines, and electrical loads must be planned early to avoid system overloads.
4. HVAC & Exhaust Systems
One of the most overlooked (but critical) parts of restaurant construction is the HVAC and exhaust system. You’ll need:
- High-powered hoods and exhaust systems to handle heavy cooking fumes
- Make-up air units (MAUs) to replace air removed by ventilation
- Grease-rated ductwork for fire safety
This isn’t a DIY job — make sure your contractor is licensed and experienced with restaurant builds.
5. Budgeting for Construction Costs
Restaurant builds vary widely depending on size, location, and design complexity. Here’s a basic range to expect in Ontario:
| Type of Work | Estimated Cost (per sq. ft.) |
|---|---|
| Basic Build-Out | $150–$250 |
| Full Custom Build | $250–$450 |
| Kitchen Equipment Installation | $50,000–$200,000+ |
| Permits and Inspections | $5,000–$20,000 |
Working with a builder who provides accurate estimates and cost transparency can help you stay within budget and avoid unpleasant surprises.
6. Timelines: How Long Does It Take?
A full restaurant build can take anywhere from 12 to 24 weeks, depending on:
- Permit approvals
- Site conditions
- Complexity of design
- Availability of materials and equipment
At Diamond Builders Group, we create detailed construction timelines and project plans to help you launch on schedule — and start serving guests sooner.
7. Choosing the Right Contractor
Your restaurant build is a serious investment. Make sure your contractor:
- Has experience with restaurant projects in Ontario
- Understands the health, fire, and building codes
- Offers design-build services to simplify the process
- Can work with your designer, chef, or operations team to bring the vision to life
