Our Proven 4‑Step Home Addition Process
We follow a structured and transparent workflow to deliver quality and consistency. Every home addition follows a clearly defined path with accountability at every stage.
01 In‑Home Consultation & Needs Assessment
This project consultation phase starts with an on-site visit where we evaluate your property’s structure, discuss your goals, and assess zoning bylaws and space limitations. We also identify any foundational or structural challenges to determine the feasibility of your vision.
02 Design, Budget & Permit Planning
Next, we move into architectural design and renovation budget planning. We develop detailed 3D home design mockups and create a realistic cost per square foot forecast. Our team handles every step of the permit application process, including committee hearings and building permit requirements.
03 Construction & Quality Assurance
Our general contractor team coordinates the full construction timeline, keeping the site safe, clean, and organized. We conduct milestone inspections to ensure work meets Ontario Building Code standards. Communication is maintained through each step of the build, giving you peace of mind.
04 Final Walk‑Through & Post‑Completion Support
Once the project is complete, we conduct a final walk-through to address any final adjustments. Post-renovation warranty services are activated at this stage, and we remain available for any follow-up care or concerns, reinforcing long-term trust.

Planning Your Home Addition in Toronto
Choosing the Right Home Addition for Your Needs
At renoWOW!, we understand that no two families—and no two homes—are the same. That’s why we tailor every home addition to your unique needs. Whether you’re expanding for a growing family, adding an income suite, or creating a private office or studio, we guide you through the best-fit options.
From second-story additions to garage conversions, our team helps you balance lifestyle goals, zoning requirements, and long-term value. With over 32 years serving Toronto homeowners, renoWOW! ensures your home addition is not only functional—but a smart investment in the way you live.
Modular vs Traditional Home Additions
When planning a custom home addition, homeowners in Toronto often weigh the choice between modular home addition options and traditional builds. Modular additions are pre-fabricated in controlled environments and then assembled on-site, reducing the construction timeline and offering cost predictability. Traditional additions, on the other hand, allow for greater architectural design flexibility and integration with existing structures but often involve longer build times and weather-related delays. renoWOW! provides expert guidance on which method suits your goals, property conditions, and renovation budget planning needs.

COMMON QUESTIONS ABOUT HOME ADDITION
How much does a home addition cost in Toronto?
At renoWOW!, most home additions in Toronto start around $200–$350 per square foot, depending on the type, finishes, and structural work required. We provide detailed quotes based on your goals, zoning limits, and site conditions—no surprises, just clear, transparent pricing.
Do I need a permit for a home addition in Toronto?
Yes, most home additions require building permits—and often zoning approvals too. At renoWOW!, we handle the entire permit process for you, including drawings and submissions, so you don’t have to worry about red tape or costly delays.
How long does a typical home addition take to complete?
On average, our home addition projects take 4 to 8 months from design to final inspection. Timelines depend on the scope, permits, and weather. We give you a realistic schedule upfront and keep you updated at every step.
Can I live in my house during the addition project?
In many cases, yes. We plan carefully to minimize disruption and keep construction zones secure. For major second-story or full-home additions, a temporary move may be needed—but we’ll always walk you through what to expect before work begins.
What’s the difference between a home extension and a second-story addition?
A home extension expands outward into your yard—great for larger lots. A second-story addition builds upward, ideal for Toronto’s narrow properties. At renoWOW!, we’ll help you choose the right option based on your space, structure, and future plans.
Will a home addition increase my property value?
Yes—when done right, additions typically boost property value. Extra bedrooms, bathrooms, or income units can significantly increase resale appeal. renoWOW! focuses on smart design and lasting quality, so your investment pays off both now and in the future.
Is it cheaper to build up or out when adding space?
Building out is often simpler and slightly less expensive, but not always feasible on tight city lots. Second-story additions cost more due to structural work but add major square footage. We assess both options based on your home and goals.
What kind of home additions are best for rental income?
Garage conversions, basement apartments, and above-garage suites are great for rental potential. We help homeowners design legal, livable spaces that meet city codes and appeal to renters—ideal for generating extra income or supporting multigenerational living.
