2026 Toronto renovation planning guide
Full home renovation
cost in Toronto.
The short answer: plan approximately $300–$400 per renovated sq. ft. for a major full-home renovation and $400–$500+ per renovated sq. ft. for a full gut renovation with substantial structural work, new mechanical systems and custom finishes.
These are early construction-planning ranges, not quotes. Add professional fees, permits, contingency, temporary housing and 13% HST to understand the full cash requirement.
Realistic early ranges
What should you plan per square foot?
Broad interior reconfiguration across multiple floors, kitchens and bathrooms, coordinated mechanical work and a considered finish package, with limited-to-moderate structural intervention.
Extensive demolition, structural changes, new electrical, plumbing and HVAC, premium kitchens and bathrooms, custom millwork and complex existing conditions.
Measure the area actually being renovated—not simply the home’s listing square footage. A smaller project can carry a higher unit cost because kitchens, bathrooms, mobilization and mechanical systems are concentrated expenses.
Addition pricing
Planning ranges by addition type.
Renovations or reconfiguration of the existing main floor are priced separately.
Typically 200–300 sq. ft. added. Pricing varies based on foundation and structural requirements, exterior finishes and the complexity of integrating the addition with the existing home.
Renovations or reconfiguration of the existing main floor are priced separately.
A complete new second storey, with pricing depending on structural requirements, layout, bathrooms, mechanical upgrades, exterior work and level of finish.
For larger additions that expand both the footprint and upper level of the home. Pricing varies based on addition size, structural complexity, approvals, interior scope and finishes.
Worked examples
What the range can mean in dollars.
Construction subtotal only, before professional fees, permits, contingency, temporary housing and HST.
1,500 sq. ft. major renovation
$450,000–$600,000At $300–$400 per renovated sq. ft. Suitable as an early test for a broad interior transformation with moderate structural scope.
2,000 sq. ft. full gut renovation
$800,000–$1,000,000+At $400–$500+ per renovated sq. ft. Appropriate when the project includes significant structural changes, systems and custom finish work.
2,000 sq. ft. renovation + 300 sq. ft. rear addition
Build the scopes separatelyPrice the renovated area using the applicable renovation range and the new rear-addition area at approximately $500–$700 per sq. ft. Then add shared site and integration costs once.
The complete budget
Construction is not the whole number.
Labour, materials, management, trades and defined allowances in the construction proposal.
Architectural or design work, structural and mechanical engineering, surveys, arborist or planning work, permit and approval fees. Use actual proposals as soon as the team is known.
A homeowner-held reserve for concealed conditions, design development and changes—not an invitation to spend more.
Confirm whether every proposal and allowance is shown before or after tax.
Rent, utilities, storage, insurance implications and two moves for the period the house cannot be occupied.
Appliances, decorative lighting, furniture, window coverings and other items excluded from the construction contract.
What moves the price
What Changes the Cost?
- 01
Structural scope
Removing bearing walls, relocating stairs, underpinning or repairing framing adds engineering, temporary support and skilled labour.
- 02
Kitchens + bathrooms
Cabinetry, stone, plumbing, waterproofing, tile, fixtures and appliances concentrate cost into relatively small areas.
- 03
Mechanical systems
Rewiring, service upgrades, new plumbing, HVAC redesign and ventilation are more efficient when coordinated before walls close.
- 04
Existing conditions
Older Toronto houses can reveal undocumented work, water damage, uneven structure, hazardous materials or inadequate services.
- 05
Finish level
Custom millwork, natural stone, specialty glazing, premium fixtures and detailed trim raise both material and installation costs.
- 06
Approvals
Zoning reviews, Committee of Adjustment, permits and consultant coordination affect soft costs and the pre-construction schedule.
- 07
Access + logistics
Narrow lots, limited parking, neighbour protection, waste handling and downtown delivery constraints affect productivity.
- 08
Decision timing
Late selections and revisions can create redesign, reordering and schedule costs that early coordination can avoid.
Professional fees + permits
Carry soft costs outside the construction subtotal.
For early planning, 8–15% of construction is a useful combined allowance for design, engineering, surveys, approvals and permits, but it is not a fee quote. Complexity and the services retained determine the actual amount.
Toronto calculates many residential renovation permit fees by the affected floor area and updates its schedule annually. Review the current City of Toronto building permit fees when the scope is defined.
HST
Tax changes the cash requirement.
Ontario HST is 13%. On an $800,000 taxable construction subtotal, 13% HST is $104,000. Ask whether every early range, professional proposal and allowance is before or after tax. The Canada Revenue Agency confirms Ontario’s 13% HST rate.
Contingency
Protect the project from what drawings cannot reveal.
Hold 10–15% of the construction budget outside the contract for many older-home renovations. Consider 15–20% when the design is preliminary, the house has known issues or substantial areas will remain concealed until demolition.
Contingency is different from an allowance. An allowance is an estimated amount for a defined item not yet selected; contingency is a reserve for uncertainty and approved changes.
Temporary housing
Budget for living somewhere else.
Homeowners should generally plan to relocate during a full gut renovation. Build a monthly housing budget for the likely construction period, then include storage, utilities, insurance implications, pet needs and two moves. Avoid assuming the earliest completion date when choosing a lease.
Cost planning FAQ
Questions to settle before design advances.
How much does a full home renovation cost in Toronto?+
For early 2026 planning, allow approximately $300–$400 per renovated sq. ft. for a major full-home renovation and $400–$500+ per renovated sq. ft. for a full gut renovation with substantial structural work, new systems and custom finishes. Add professional fees, permits, contingency, temporary housing and HST.
How much does a Toronto home addition cost?+
Plan approximately $500–$700 per sq. ft. for a rear addition and $450–$650 per sq. ft. for a full second-storey or combined rear plus second-storey addition. Renovations or reconfiguration of the existing main floor are priced separately.
How much contingency should we carry?+
Plan on 10–15% of construction for many older Toronto houses. Consider 15–20% when drawings are preliminary, access is difficult or concealed conditions are especially uncertain.
Does the renovation estimate include HST?+
Confirm this explicitly. Ontario HST is 13%, and it materially changes the cash required when a proposal or early planning range is stated before tax.
Are appliances and temporary housing included?+
Not automatically. Keep a separate owner-cost schedule for appliances, decorative lighting, furniture, window coverings, rent, storage, utilities and moving.
When can we establish a property-specific budget?+
After the house, intended scope, existing conditions, design direction and approval path have been reviewed. The budget becomes more reliable as drawings, engineering and selections are resolved.
