Office Renovation — Tenant Improvement
Office tenant improvements in GTA typically run $60–$150/sqft for a complete fit-out including:
- Demising walls and glass partitions
- Electrical — new circuits, lighting, data infrastructure
- HVAC — zone controls, duct modifications
- Flooring — commercial carpet or LVT
- Millwork — reception desk, kitchenette, storage
- Washroom upgrades if required
Many commercial leases include a Tenant Improvement (TI) allowance from the landlord — typically $30–$60/sqft. Dotch Construction can work directly with your landlord and property manager to maximize your TI budget.
Medical & Dental Clinic Renovation
Medical and dental offices have the highest cost per sqft of any commercial renovation due to specialized mechanical requirements:
- Plumbing — multiple wet locations (dental chairs, exam rooms, sterilization areas)
- Electrical — high-amperage circuits for dental equipment, medical gas lines
- HVAC — specialized ventilation, negative pressure rooms
- Accessibility — AODA compliance required
- Lead-lined walls — X-ray rooms require lead shielding
- Infection control — specific materials and sealing requirements
A complete dental office build-out for a 2,000 sqft clinic typically costs $400,000–$700,000 including all equipment rough-ins and specialized systems.
Restaurant Renovation
Restaurant renovations are among the most complex commercial projects due to the density of mechanical systems required:
- Commercial kitchen exhaust and ventilation
- Gas lines for commercial cooking equipment
- Grease traps and specialized plumbing
- Fire suppression systems
- Health department compliance
- LLBO (Liquor License) requirements if applicable
A restaurant fit-out in Toronto typically costs $100–$250/sqft. A 1,500 sqft restaurant runs $150,000–$375,000 for a complete build-out.
Key Considerations for Commercial Projects
Business Continuity
Unlike residential renovations, commercial renovations often need to happen while the business remains partially operational. Dotch Construction plans phased work schedules to minimize disruption to your business.
Building Permit & Inspection
All commercial renovations in Ontario require a building permit. Work must be inspected at key stages — framing, mechanical rough-in, and final inspection. Dotch Construction manages the entire permit process.
AODA Accessibility Compliance
The Accessibility for Ontarians with Disabilities Act (AODA) requires that commercial spaces be accessible. Any renovation triggering significant work must include accessibility upgrades — ramps, accessible washrooms, door width requirements.
Landlord Approval
If you're a tenant, all renovation work requires landlord approval. Dotch Construction has extensive experience working with Toronto commercial property managers and can help navigate the approval process.
