Frequently Asked Questions About Sunrooms In Toronto
How much does a sunroom addition cost in Toronto?
The cost of a sunroom addition in Toronto generally ranges from $35,000 to $100,000 per square foot.
Pricing depends on the size, design complexity, materials, and any required structural work.
Site conditions and finish levels can also impact the final price. We provide clear, detailed estimates upfront so you know exactly what to expect before construction begins.
Is it cheaper to build a sunroom or an addition?
In most cases, building a sunroom is cheaper than a full home addition.
Sunrooms typically require less structural work, fewer utilities, and simpler insulation, especially if it's a 3-season room.
However, costs can rise for 4-season sunrooms with full HVAC, high-end finishes, or complex designs. The right choice depends on how you plan to use the space and your overall budget.
Do I need a permit to build a sunroom in Toronto?
Yes, you typically need a building permit to construct a sunroom in Toronto.
Whether it’s a 3-season or 4-season sunroom, the city requires permits to ensure the addition meets zoning bylaws, building codes, and structural safety standards.
At TGC, we handle the entire permitting process for you to keep your project compliant and stress-free.
Do sunrooms increase home value?
Yes, sunrooms can increase your home's value by adding usable square footage, enhancing natural light, and improving overall appeal. A well-designed sunroom - especially a fully insulated 4-season space - can boost resale value and attract buyers looking for flexible living areas like home offices, reading lounges, or garden retreats.
Can I live in my home while the sunroom is being built?
Yes, in most cases you can live in your home while the sunroom is being built.
Since sunroom additions are typically separate from main living areas, construction can often take place with minimal disruption.
However, we’ll always assess your specific project to ensure safety and convenience throughout the process.
What’s included in your design-build process?
Our design-build process includes everything from initial concept planning and architectural drawings to permit applications and final construction.
You’ll work with a dedicated project manager throughout the process who serves as your single point of contact, ensuring a smooth and coordinated experience from start to finish.
