How Much Does It Cost To Remodel a House in Toronto?

Remodeling a house in Toronto can range from about $50,000 for smaller single-room updates to $550,000+ for large structural additions and full-floor expansions. 

Costs vary widely based on the type of project, the square footage involved, and the level of finishes you choose. 

Here is a clear breakdown of what homeowners can expect when planning a remodel in Toronto.

Kitchen Renovation Costs in Toronto

Kitchen remodels are one of the most significant upgrades you can make to a Toronto home, and they typically fall between $50,000 and $150,000 or more. Smaller kitchens with modest layouts and standard materials land near the lower end of the range. These projects usually include new cabinetry, updated counters, improved lighting, flooring, and appliance upgrades without major structural changes.

Most homeowners, however, fall into the mid-range, where budgets of $75,000 to $100,000 allow for semi-custom cabinetry, quartz countertops, upgraded lighting design, and moderate layout adjustments. Larger or luxury-level kitchens with custom millwork, premium appliances, stone surfaces, and full layout reconfigurations often reach $100,000 to $150,000+. Kitchens are labour-intensive and involve plumbing, electrical, ventilation, installation, and high-value materials, which is why they consistently represent one of the highest renovation costs per square foot.

Basement Renovation Costs in Toronto

Basement remodeling costs range from $25 to $150 per square foot or $25,000 to $150,000, for a finished 1,000 square foot project. depend heavily on the condition of the existing space and the purpose of the renovation. A basic finish focuses on insulation, flooring, drywall, trim, lighting, and painting, while more involved basement projects can add bathrooms, bedrooms, laundry rooms, wet bars, or full rental suites. As the scope grows, the cost rises, especially when plumbing and HVAC upgrades are required.

Many older Toronto basements need underpinning, waterproofing, or structural adjustments before finishing work can begin. These factors are major contributors to total budget. Although Toronto General Contractors publishes basement renovation guidance in a dedicated article, the themes are consistent: a well-planned basement remodel is a major transformative project that can significantly increase both value and livable square footage.

Second-Story Addition Costs in Toronto

Adding a second story to a Toronto home, especially a bungalow, is one of the largest-scale remodels available and typically costs between $250,000 and $550,000+. These projects often involve adding 800 to 1,500+ square feet of new space, including bedrooms, bathrooms, a laundry room, and a redesigned circulation system with a new staircase.

The lower end of the range reflects straightforward additions with standard finishes and limited changes to the main floor. As designs become more complex, or when higher-end finishes are used, costs rise. Reconfiguring the main floor, adding structural reinforcement, or incorporating premium exterior and interior materials contributes significantly to the upper end of the cost spectrum.

Design, engineering, and permitting are critical components of these projects. Toronto General Contractors emphasizes that zoning rules, structural requirements, and permit timelines all influence both the cost and duration of the remodel. A second-story addition delivers one of the largest increases in square footage and property value but requires careful planning.

Four-Season Sunroom Costs in Toronto

A four-season sunroom is designed as a fully conditioned, year-round living space. Costs vary from $35,000 - $100,000 depending on size, insulation, glazing quality, HVAC requirements, and the chosen foundation type. According to Toronto General Contractors, four-season sunrooms function similarly to traditional additions in terms of construction complexity. They must be engineered for Toronto’s climate, tied into the existing home, and finished to interior-grade standards.

This places them in a mid-to-upper cost range for home additions. While more affordable than a full second story, they are more complex and expensive than cosmetic remodels because they require roofing, insulation, windows, mechanical integration, and weather-tight construction.

Garage Addition Costs in Toronto

Garage additions, whether attached or detached, range from $60,000 to $120,000+. They require a foundation, framing, roofing, siding, and electrical work. Toronto General Contractors notes that garage additions are often more affordable than habitable room additions because they typically require fewer interior finishes. However, the exact cost depends on whether the garage is attached, incorporates storage or workshop space, or includes insulation and heating.

Garages provide functional square footage that homeowners can use for parking, storage, or future conversion. Even though they generally cost less per square foot than living-space additions, they still involve significant construction components, making them a meaningful part of a whole-home remodel budget.

What a Full Toronto Home Remodel May Cost

When homeowners combine multiple projects—such as remodeling the kitchen, finishing the basement, and building a sunroom or second-story addition—the cost quickly scales into the mid-to-high six figures. For example, pairing a $75,000–$150,000 kitchen with a complete basement renovation and adding a four-season sunroom can easily surpass $200,000 to $300,000. Adding a second story pushes a remodel into an even higher range, often landing between $300,000 and $550,000+ depending on the size and design.

This is why Toronto General Contractors emphasizes planning, sequencing, and design integration for homeowners tackling multi-project remodels. Coordinating structural work, layout changes, mechanical upgrades, and inspections can reduce inefficiencies and keep costs predictable.

Factors That Influence Toronto Remodel Costs

Several elements consistently shape the total price of a home remodel in Toronto. Structural changes, such as removing load-bearing walls or reinforcing foundations, quickly increase costs. Plumbing and electrical reconfiguration also adds complexity, as do HVAC upgrades. Finish levels - ranging from builder-grade to high-end custom materials - strongly influence the final number.

Local permitting, engineering requirements, and Toronto’s construction standards also contribute meaningfully to budgeting. Finally, the age and condition of the home are major variables, with older properties often needing more upgrades to meet today’s building codes.

Final Thoughts

The cost to remodel a house in Toronto varies widely depending on the type of renovation, scale of work, and finish level. Kitchen remodels often start around $50,000, basement renovations depend on scope and structure, four-season sunrooms offer a mid-to-high cost addition, garage builds add functional space at a moderate cost, and second-story additions range broadly from $250,000 to $550,000+. Whether you plan a single-room renovation or a major home transformation, working with a full-service contractor like Toronto General Contractors ensures accurate design, permitting, budgeting, and execution from start to finish.
