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.

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 Rise of Multiplex Conversions in Etobicoke ON
The housing landscape in Etobicoke is undergoing a significant transformation as homeowners and investors pivot toward high-density residential solutions. Multiplex conversions—the process of turning single-family detached homes into duplexes, triplexes, or fourplexes—have become the preferred method for increasing property yield without the high costs of a complete teardown. In neighborhoods like Humber Bay, where the demand for modern living spaces near the lake is at an all-time high, these conversions provide a sustainable way to house more residents while maintaining the historical charm of the streetscape. Unlike standard home renovations, a multiplex project requires a deep understanding of multi-unit fire separations, soundproofing between floors, and individual utility metering to ensure high-quality tenant experiences.
According to recent data on multiplex development trends, permit activity for 2-4 unit buildings has surged across Toronto, tripling in volume since the 2023 zoning amendments. This shift is particularly visible in Etobicoke's RD (Residential Detached) zones, where the expansive lots of the post-war era provide the ideal footprint for rear-yard additions or internal suite divisions. Homeowners are increasingly looking at their properties as long-term investment vehicles, utilizing the EHON multiplex framework to add up to three additional units within an existing building envelope. This "as-of-right" permission has reduced the traditional barriers of NIMBYism and long-drawn-out OMB hearings, though site-specific technical reviews remain mandatory.
Working with Built by Pros Inc. ensures that your conversion is not just a renovation, but a strategic asset upgrade. We specialize in navigating the complexities of the Ontario Building Code (OBC) while ensuring that the aesthetic of the building remains consistent with the prestigious avenues of neighborhoods like The Kingsway. Our team handles everything from the initial structural audit to the final occupancy permit, often incorporating aging in place features into primary units to allow owners to downsize into their own income-generating properties. By choosing a conversion over a custom home rebuild, you are choosing a faster route to market and a more environmentally conscious way to build, preserving the structural carbon already embedded in your home.
Local Considerations and Regulatory Navigation in Etobicoke
Navigating the regulatory waters of Etobicoke requires a builder who understands the specific jurisdiction of its local building departments and the nuances of the City of Toronto’s zoning by-law 569-2013. Since May 2023, the allowance of up to four units on most residential lots has opened the door for projects in Mimico and beyond, but successfully obtaining a permit requires more than just a conceptual sketch. The city requires a comprehensive set of documents, including a survey showing all current rights-of-way and a fully dimensioned site plan that accounts for landscaped open space and parking requirements. While Ontario Bill 23 has eased some development charges, local site-specific reviews are still used to determine how new utility services—such as upgraded water mains for fire sprinklers—will be integrated.
Climate also plays a significant role in Etobicoke multiplex designs. Given our proximity to the lake, moisture management and high-efficiency HVAC systems are non-negotiable for multi-unit dwellings. Unlike a single-family home where heating imbalances are an annoyance, a duplex or triplex must provide independent climate control for each tenant to prevent disputes and comply with modern building standards. This often involves intricate ductwork or the installation of ductless split systems, which are more efficient for the diverse floor plans found in Rexdale's post-war bungalows. Furthermore, the structural integrity of older Etobicoke foundations must be assessed before adding the weight of a third or fourth unit; often, underpinning or benching is required to create high-ceiling basement units that meet the legal multi-unit criteria.
Specific challenges such as managing construction staging on the leafy, narrow streets of The Kingsway or Rexdale require a meticulous logistical plan. Built by Pros Inc. manages this process by coordinating with local neighbors and city officials to ensure that the increased density doesn't result in local traffic headaches. We emphasize the use of high-performance fire separations and resilient channels for soundproofing, ensuring that a converted triplex in Mimico feels as private as a standalone detached home. Our expertise ensures that every unit—whether a garden suite or a top-floor studio—is bathed in natural light and optimized for the unique lot orientations common in the western GTA, turning regulatory hurdles into design opportunities.
Pricing Factors and Budgeting for Etobicoke Conversions
Budgeting for a multiplex conversion in Etobicoke depends heavily on the existing condition of your property and the desired number of units. According to local cost estimates, a basic two-unit basement legalization or simple duplex conversion generally starts between $100,000 and $250,000. For homeowners looking to maximize their footprint with a three-unit conversion involving structural modifications and floor-plan reconfigurations, the budget typically ranges from $250,000 to over $500,000. These costs account for the specialized labor required for fire-rated drywalling, plumbing stacks for multiple kitchens, and separate electrical panels. In areas with older housing stock like Rexdale, homeowners should also reserve a contingency fund for potential mechanical upgrades, such as replacing lead water pipes or upgrading 60-amp electrical services to 200 or 400 amps to support multiple dwellings.
Material availability and seasonal fluctuations also impact pricing in the GTA. Winter conversions in Etobicoke often face higher costs for concrete work or exterior plumbing due to the need for heated enclosures, though interior-focused projects can often proceed at standard rates. Furthermore, the permit and professional fees—including architectural drawings and structural engineering sign-offs—often account for 10% to 15% of the total budget. While these upfront costs may seem high, the return on investment (ROI) in the Etobicoke rental market is substantial. A well-executed conversion in a high-demand area like Humber Bay can command premium rents that triple the property's gross income compared to a single-family tenant.
Investors must also consider the cost of "soft" requirements such as sound attenuation and fire safety. Unlike a standard home addition, multiplexes are held to more stringent fire codes under Part 11 of the OBC. This means that if you are converting a 1950s bungalow into a triplex, you must invest in fire-stopping at every penetration and potentially install a localized sprinkler system if exit paths are constrained. Built by Pros Inc. provides transparent, itemized quotes that break down these specialized requirements, avoiding the 'hidden surprises' that often plague inexperienced contractors. By locking in prices and selecting finishes early in our comprehensive process, we help our Etobicoke clients secure financing with confidence and ensure their projects stay on track.

Multiplex Conversions in Etobicoke: Your Questions Answered
Can any home in Etobicoke be converted into a fourplex?
Most residential detached (RD) lots in Etobicoke now allow up to four units as-of-right thanks to the 2023 zoning changes. However, site-specific limitations such as lot width, existing trees, and parking requirements under Zoning By-law 569-2013 still apply. We perform a detailed feasibility study and architectural review to ensure your specific property meets the necessary criteria before we begin the permit application process.
How does Bill 23 affect my development charges in Etobicoke?
Ontario Bill 23 provides significant relief for certain multiplex projects by exempting or reducing development charges for 'additional residential units'. For an Etobicoke homeowner adding a second or third unit, this can result in savings of tens of thousands of dollars. We work closely with our planning consultants to ensure you take full advantage of these provincial incentives while remaining compliant with current City of Toronto financial bylaws.
What are the specific parking requirements for a multiplex in Toronto?
Under the new multiplex policies, many residential lots in Etobicoke no longer require providing one parking space per unit, especially in areas well-served by transit. However, we still have to provide a site plan that shows how existing parking is managed and ensures that no new driveways violate city bylaws regarding soft landscaping. We help you navigate these rules to maximize your green space while still providing the amenities your future tenants will demand.
Do I need a separate water and electrical meter for each unit?
While not strictly required by the building code for all projects, we highly recommend separate metering for any Etobicoke multiplex conversion to simplify property management. Installing separate electrical panels and sub-meters for water and gas allows tenants to pay for their own usage, which typically increases the property's resale value and net operating income. It requires coordination with Toronto Hydro and Enbridge, a process we handle entirely as part of our mechanical planning phase.
