Toronto Building Permits for Home Additions
If you’re planning a home addition in Toronto, getting the right permits is a must. Don’t worry—we take care of everything, but here’s a quick look at what’s involved:
I. Building Permit – Required for any structural changes to your home. The city checks your plans to make sure they meet safety and building codes. You can find more details in Toronto’s official permit guide.
II. Committee of Adjustment – If your addition doesn’t follow local zoning rules (like how close it is to your neighbour’s property), we may need to apply for a minor variance. This includes a hearing and takes extra time.
Learn more about minor variances and consent applications.
III. Heritage Permit – If your home is in a heritage district, special approval is needed to keep the area’s historic character.
IV. TRCA Review – Homes near ravines or rivers might need extra approval from the Toronto and Region Conservation Authority.
How long does a Toronto Building Permit take?
We typically submit applications 4–6 weeks before construction begins. A standard Toronto building permit review takes about 10–15 business days, depending on the project scope and approvals needed.

What are the benefits of a home addition versus moving?
A home addition offers several advantages over moving:
Cost Savings: Adding space is often more cost-effective than buying a new, larger home, especially when considering real estate fees, moving expenses, and potential renovation costs in a new property.
Stay in Your Neighborhood: You can remain in the community you love, with your preferred schools, amenities, and social connections.
Customization: A home addition allows you to create a space that perfectly suits your needs and style, something you may not find in an existing home.
Investment: A well-designed home addition can significantly increase your property value, providing a strong return on investment.
Convenience: Avoid the stress and upheaval of moving, including packing, unpacking, and adjusting to a new environment.
How disruptive is a home addition to daily life?
Clear Communication: We provide a detailed project timeline and keep you informed of progress, potential disruptions, and any schedule changes.
Dust and Noise Control: We use dust barriers, air filtration systems, and other measures to control dust and debris. We also schedule noisy work during reasonable hours.
Site Management: We maintain a clean and organized work site, minimizing disruption to your property and neighborhood.
Temporary Access: We ensure you have safe and convenient access to essential areas of your home throughout the project.
Phased Construction: We may phase the construction to minimize the impact on your daily routines, such as completing the exterior shell before working on the interior.
Living On-Site: For side and rear additions, you can typically remain in your home. Second-story additions may require temporary relocation during certain phases.
Our goal is to make the process as smooth and stress-free as possible.
How Do Additions Affect Property Value?
Well-designed additions typically return 70-85%+ of their cost in increased property value. For example, a $150,000 addition might increase your home’s value by $105,000-$127,500+.
ROI depends on:
- The addition’s type and quality
- Neighborhood and market conditions
- Design and integration
- Materials and workmanship
Highest returns typically come from:
- Master suite additions
- Open-concept kitchen and family room expansions
- Second-story additions
- Income suite creation
- Enhanced curb appeal
We provide insights on how your addition may impact property value during your consultation.
