Read on GoogleWe recently completed a full home renovation plus addition with Built By Pros and we were so happy with our decision! We looked at many different companies and ultimately decided on Built By Pros after meeting with Ricardo and Suzanne and getting a good feeling from them right off the bat. They were very helpful and involved in every step of the process which gave us complete trust and confidence in them. They hold themselves to a high quality and customer service standard and it shows through their approach and their work.
The whole team was great to work with. The crew was friendly, respectful, helpful and went the extra mile to ensure all our requests were accommodated. The project was on budget and on time and we couldn’t have asked for a smoother process.
We have now moved into our new house and are loving our new space. If you’re looking to do a home reno, look no further than Built By Pros!

Read on GoogleIncredible team to work with, exceptional quality of work!
We've just underwent a major home renovation - When you are taking on a project of this magnitude, you need to have trust in your partners, and the Built by Pros team earned our trust every step of the way. They worked tirelessly to get the job done on time, and to a high quality of finish. They were honest and open in their communications - which is so important when you are renovating a 100+ year old home and bound to discover some issue hidden behind dry wall. They were reasonable in their pricing - the team has a great designer and architect who helped us find creative design solutions that helped us fall in love with our house, but also do it within budget.
For people in the GTA considering a home reno - we highly recommend this team.

Read on GoogleI chose Built By Pros for my en suite bathroom renovation after meeting with them at the Toronto Home Show. From the initial meeting with Suzanne to subsequent conversations about what I wanted for the renovation as a part of the contract signing - the process was smooth and feedback was always heard and quickly addressed. I felt very comfortable moving forward with the contract and project given the amount of details provided for the initial assessment and a clear understanding of the project milestones, cost and timelines. It was a pleasure working with Suzanne and Petra through the planning and construction - I had an idea / vision of what I wanted the bathroom to look like and they both made sure it was possible, down to every last detail. The crew was also great - very meticulous with their work and receptive to feedback (also very detail oriented which was excellent).
The bathroom construction timeline itself was extended a bit but was totally worth the wait. It is beautiful, functional and exactly what I hoped for. I would highly recommend Built By Pros for your construction project.

Learn MoreThe Evolution of East York Housing and the Need for Space
East York is characterized by its unique architectural history, featuring a mix of post-war bungalows and 1920s-era residential properties. As families grow, these charming but often compact 800 to 1,400 square foot homes require strategic expansion to meet the demands of modern life. In neighborhoods like Parkview Hills, homeowners frequently find that their existing footprint no longer supports a home office, a primary suite, or a spacious kitchen. This is where Home Additions in East York become the most viable path to increasing property value while avoiding the high costs of moving in the current Toronto real estate market. Many residential lots in the area are generous, often spanning 30 to 40 feet in width and reaching depths of 120 feet, which provides significant opportunity for rear extensions.
Choosing to build an addition requires a deep understanding of local infrastructure. According to the East York housing and renovation context, the aging plumbing and electrical systems common in these older homes must be carefully integrated with new construction. Whether you are considering a full custom home rebuild or a targeted extension, it is vital to work with a team that respects the historical neighborhood fabric while implementing high-efficiency modern materials. At Built By Pros Inc., we specialize in bridging this gap by providing full-service design, permit, and build solutions that respect the local character of areas like Olde East York.
Furthermore, the trend toward multi-generational living has increased the demand for multiplex conversions in East York. By adding a lateral extension or a nested apartment above a garage, homeowners can create autonomous living spaces for aging parents or adult children. These projects are governed by specific provincial and municipal standards that require professional oversight to ensure long-term safety and compliance. Our decades of experience in the Greater Toronto Area allow us to navigate these complexities smoothly, ensuring that your home addition feels like a natural part of the original structure rather than an afterthought.
Navigating Zoning By-laws and Permits in East York
The regulatory landscape in East York is governed primarily by East York By-law 6752, which sets strict parameters for setbacks and lot coverage. For example, detached dwellings in the R1A to R1C zones typically must adhere to a front yard setback of 6.0 meters and side yard clearances between 0.6 and 0.9 meters. Understanding these measurements is critical during the initial design phase to prevent costly delays at the Committee of Adjustment. Many property owners in Pape Village find that even minor deviations from these rules necessitate a minor variance application, which can add significant time to the project schedule.
Building permits are mandatory for any structural addition, particularly for projects that exceed 100 square meters. According to the City of Toronto's guide on small residential additions, homeowners must also post a Residential Infill Construction Public Notice on-site. This transparency ensures that neighbors are informed of the development, which is a standard procedure meant to maintain community harmony during construction. Our architectural and engineering partners are well-versed in these specific East York requirements, handling everything from CAD drawings to final inspections to ensure your project remains fully compliant with the Ontario Building Code.
Beyond simple footprint changes, the City of Toronto also oversees vertical expansions. For those seeking home renovations in East York, adding a second story is a popular way to double the square footage of a bungalow. This approach often triggers specific zoning restrictions related to the angular plane and maximum building heights, which vary by street. A professional contractor must evaluate the existing foundation's load-bearing capacity before adding vertical mass. At Built By Pros Inc., we conduct thorough site assessments to determine if underpinning or structural reinforcement is necessary, providing a solid foundation for your family’s future.
Pricing Factors and Budgets for Home Additions in East York
Budgeting for a major construction project in East York requires a nuanced understanding of current market rates and localized costs. According to data provided by BVM Contracting, homeowners should expect to pay between CAD 325 and CAD 450 per square foot. This range covers the core addition as well as the necessary integration and renovation of the existing adjacent spaces. Professional fees, including architectural and engineering services, typically range from CAD 20,000 to CAD 40,000 depending on the complexity of the interior design and technical requirements of the build.
Several factors can influence the final cost. Permits and administrative fees usually amount to CAD 2,000 to CAD 8,000, while navigating the Committee of Adjustment, if required for a minor variance, can cost an additional CAD 3,000 to CAD 5,000. It's also important to account for seasonal pricing; construction costs often fluctuate based on the availability of trades and raw materials. In East York, seasonal ground conditions can also impact excavation costs for rear additions, particularly during the spring thaw when site access and mud management become more challenging for workers. Our team provides transparent, itemized quotes to ensure there are no surprises during the build.
Additionally, the choice of finishes and mechanical updates can shift the budget significantly. Upgrading an older HVAC system to support a new second story is an essential investment that ensures comfortable year-round temperatures. Many East York residents also choose to combine their addition with aging in place renovations to ensure their home remains functional for decades to...

Local Considerations and Climate Resiliency
Building in East York, Toronto, means designing for a climate that experiences extreme seasonal shifts. A home addition must be thermally efficient to withstand harsh winters and humid summers. We prioritize high-performance insulation and vapor barriers that exceed the standard Ontario Building Code to promote energy savings. In neighborhoods like Parkview Hills, where homes are often tucked into leafy pockets, managing moisture and potential flooding from mature tree canopies is also a consideration. We ensure that all roofing and drainage systems are integrated flawlessly with the existing house to prevent ice damming and water ingress.
Another specific local consideration is the type of soil found in the Don Valley area. Some sections of East York feature silty or clay-heavy soils that may require specialized foundation work, such as helical piles or deeper footings, to guarantee the stability of the addition. Older infrastructure in neighborhoods like Olde East York can also present challenges regarding sewer line capacity when adding new bathrooms. Before we break ground, we coordinate with the City of Toronto to verify that the local services can handle the increased load of your expanded home. We also assist with commercial renovation projects in the area that require similar infrastructure upgrades.
Common housing stock, specifically the 1.5-story 'war bungalows,' offers a unique advantage for vertical expansion. Because these homes have smaller footprints, they often have ample yard space to accommodate a generous rear expansion. This allows homeowners in Pape Village to keep their backyard while still gaining the indoor space they need. By choosing a local specialist like Built By Pros Inc., you benefit from our 18 years of experience navigating these exact lot conditions and historical architectural styles, ensuring your renovation is both beautiful and structurally superior.

Home Additions in East York: Your Questions Answered
How much does a typical home addition cost in East York?
A high-quality addition in East York generally ranges from $325 to $450 per square foot. This includes all construction labor, premium materials, and necessary renovations to the existing structure to accommodate the new space. Factors such as custom finishes, structural underpinning for basements, or specialized mechanical upgrades will influence the final cost. We provide a detailed, itemized quote after our initial site visit so you can budget with total confidence.
Will I need to move out during construction of my addition?
For major second-storey additions, we usually recommend moving out for 3 to 5 months while the roof is off and the main structural work is performed. For smaller rear extensions, it may be possible to remain in the home if the construction area can be safely sealed off from the living quarters. We prioritize keeping the job site clean and minimizing disruption, and we will discuss all living arrangements during the project planning phase. Our goal is to ensure your family's safety and comfort throughout the entire process.
How long does the permit process take with the City of Toronto?
The timeline for permits in East York typically takes between 2 to 4 months for straightforward applications. If your project requires a minor variance through the Committee of Adjustment, you should plan for an additional 3 to 5 months for the hearing and appeal period. We handle all documentation and representation for these meetings, which boasts a high success rate due to our deep knowledge of local zoning by-laws. Early planning is key to ensuring your construction starts on your desired timeline.
Can you match the existing look of my older East York home?
Yes, matching the character of your original home is one of our signatures. Whether you have a heritage brick exterior or unique architectural trim, our sourcing team finds materials that blend the addition seamlessly with the existing house. We work with specialized masons and carpenters who understand the textures and techniques used in 1920s and post-war construction. This ensures your home maintains its market value and fits perfectly within your established neighborhood aesthetic.
