Transform your Scarborough property into high yield rental units with expert design and construction.
We focus on high-yield configurations that maximize every square inch of your Scarborough property. Our designs prioritize features that increase rental rates, such as private entrances, in-suite laundry, and modern kitchenettes, ensuring your conversion pay for itself quickly through consistent cash flow.
We handle the complex zoning and permit applications required by the City of Toronto for Scarborough residential areas. This includes ensuring full compliance with the Ontario Building Code, fire safety regulations, and egress requirements, giving you peace of mind and a fully insurable investment.
Our multi-unit conversions utilize advanced sound-dampening technologies including Sonopan panels and resilient channeling. This minimizes noise transfer between units in your Scarborough home, which is the number one cause of tenant turnover and disputes, ensuring a peaceful environment for all occupants.
We begin with a thorough inspection of your Scarborough property's structural integrity and local zoning status. We identify any obstacles to legality, such as insufficient ceiling height or parking constraints, before any money is spent on design. This prevents the common pitfall of planning a conversion that the City of Toronto will ultimately reject.
Our architects create detailed drawings that maximize space and light while meeting all Ontario Building Code requirements. We handle all interactions with Scarborough's building department, managing the application process from start to finish. This ensures that the permits are issued as quickly as possible, allowing us to break ground without unnecessary delays.
During construction, we prioritize the 'invisible' infrastructure like plumbing, electrical upgrades, and soundproofing. We maintain a clean and safe worksite to minimize disruption to you or your existing tenants. Our site supervisors, like Marco or Bastian, monitor quality daily to ensure every stud and wire is installed precisely according to the approved plans.
We coordinate all mandatory city inspections to ensure the work is signed off at every stage, from framing to final occupancy. The project concludes with a detailed walkthrough to ensure every finish meets our high standards. Once we hand over the keys, your new Scarborough multi-unit space is fully legal and ready for immediate tenant move-in.
Eligibility depends on several factors including ceiling height (typically 6'5" minimum under beams), the presence of adequate parking, and zoning bylaws. In Scarborough, most residential properties are now eligible for secondary suites under recent city-wide zoning changes. We offer a preliminary site assessment to check your foundation, plumbing depth, and egress possibilities before you commit to the project.
Costs vary significantly based on the existing state of the property, but a standard basement-to-apartment conversion in Scarborough usually starts around $80,000 to $120,000. Factors like the need for underpinning, separate utility metering, and the level of finishes will impact the final price. We provide a detailed fixed-price contract after the design phase to ensure there are no surprises during construction.
Fire separation is achieved through a combination of Type X fire-rated drywall on ceilings and walls, along with specialized mineral wool insulation (like Roxul) for its fire-resistant properties. We ensure all ductwork and pipe penetrations are sealed with fire-caulking. In Scarborough, we strictly follow the City of Toronto's requirement for interconnected smoke and CO alarms to ensure that if one unit detects a fire, the entire building is alerted immediately.
Almost certainly. Most single-family homes in Scarborough have a 100-amp service, which is insufficient for two or more modern households with electric appliances. We typically upgrade clients to 200-amp or 400-amp service. We also recommend sub-metering so tenants can be responsible for their own electricity usage, which significantly reduces the landlord's monthly overhead and encourages energy conservation.

Learn MoreBuilt By Pros Inc. transformed my large bungalow basement into a stunning two-bedroom legal suite. They navigated the tricky Scarborough zoning permits flawlessly and finished the project in exactly 12 weeks. The quality of the soundproofing they installed between floors is incredible; I can't even hear the tenants below. Their use of high-end vinyl plank flooring and custom cabinetry made the unit so attractive I had it rented within three days of listing.
We hired Ricardo and his team to turn our detached garage into a garden suite. Despite the tight space and local drainage challenges we face in this part of Scarborough, they engineered a perfect solution. The modern finishes, especially the quartz countertops and recessed lighting, really elevated the space. The project was completed within our budget, and the communication throughout the demolition and construction phases was outstanding.
I've worked with several contractors in the past, but Built By Pros is the only one I'll use for my rental properties now. They converted my older three-story home into a triplex, managing all the separate electrical meters and plumbing stacks. They handled a unique challenge with the main sewer line which saved me thousands in potential future repairs. The project took about five months, which was exactly what they quoted at the start.
