Maximize your real estate investment returns with expert multi-unit design and construction services.
Our designers create specialized architectural layouts that maximize human-centric floor area while ensuring full compliance with fire safety codes. We focus on eliminating wasted hallway space to increase bedroom counts or living room dimensions in tight urban footprints. This expert planning can increase your potential rental yield by up to 30% compared to standard generic layouts.
We install high-performance sound dampening systems and fire-rated barriers that exceed the standard Ontario Building Code requirements. By utilizing specialized insulation and staggered stud wall construction, we create independent living environments that feel private and secure. This reduces tenant friction and protects your liability as a property owner across multiple units.
We handle the complex plumbing and electrical engineering required to separate utility services for each individual unit. This allows you to transfer the responsibility of electricity and water costs directly to your tenants, significantly lowering your overhead. Our team coordinates with local utility providers in Toronto and Vaughan to ensure all connections are professional and legally certified.
We begin with a deep dive into your property's specific zoning bylaws and structural potential. We identify the maximum allowable density for your lot and check for common pitfalls like inadequate ceiling heights or parking requirements. This step ensures you don't spend money on designs that the city will ultimately reject.
Once a strategy is set, we create detailed CAD drawings that optimize the floor plan for maximum rental return. We handle the entire application process with the city building department, navigating the back-and-forth required for building permits and Committee of Adjustment if necessary. This removes the administrative burden from you while ensuring 100% legal compliance.
Construction starts with the foundational elements often hidden behind walls: upgraded electrical panels, new plumbing stacks, and fire-resistant framing. We prioritize these core systems to ensure that each unit functions independently and safely, preventing future maintenance headaches. This phase is critical for passing the city's mandatory inspections before we move to finishing work.
The final stage involves high-quality finishing—cabinetry, flooring, and paint—tailored to attract premium tenants. We perform a final walkthrough to ensure every detail meets our 'Built By Pros' standard and assist with obtaining the final occupancy permits from the city. This allows you to list your units on the market immediately with full confidence in their quality and legality.
Most residential properties in Toronto are now eligible for some form of multi-unit conversion, following the city's Multiplex policy changes. However, eligibility depends on specific factors like lot size, parking availability, and existing structural integrity. We conduct a thorough feasibility study during our initial consultation to determine exactly how many legal units your property can support given current zoning and the Ontario Building Code.
A standard multi-unit conversion generally takes between 4 to 8 months, depending on the complexity of the project and the speed of city permit approvals. The design and permitting phase often takes 2-3 months, followed by active construction which usually lasts 3-5 months for internal renovations. Larger projects involving external additions or separate garden suites will naturally require additional time for site preparation and structural work.
While every project is unique, a legal basement suite conversion in the GTA typically starts around $100,000 to $150,000. This price includes crucial elements like separate entrances, fire-rated exits, independent heating/cooling systems, and full kitchen/bathroom installations. We provide a detailed quote that breaks down these costs so you understand exactly where your investment is going and can accurately project your rental ROI.
Yes, converting a single-family home into a multi-unit property generally increases the assessed value of your home, which will reflect in your property taxes. However, the additional rental income generated usually far outweighs the increase in tax obligations. We can help you estimate these costs as part of your investment planning to ensure the project remains financially viable over the long term.
Transform your property into a high-value asset by navigating Toronto's specific legal requirements for basement apartments and garden suites.

Learn MoreI hired Built By Pros to convert my North York bungalow into a legal duplex, and the results were incredible. Suzanne and Ricardo managed the entire permit process with the city, which was a huge relief given the zoning changes last year. They finished the 1,200 sq ft basement suite in under 4 months, using high-end quartz counters and luxury vinyl flooring that looks amazing. The soundproofing between the two floors is so good I can barely hear the tenants walking upstairs.
We worked with the team to optimize a large commercial-residential mix property in East York. They managed to find space for an additional studio unit we didn't think was possible by reconfiguring the old stairwell and storage rooms. The craftsmanship on the custom cabinetry in the micro-kitchens is top-notch, and they even handled the complex HVAC separation. Every step of the way, Marco kept us informed of the progress, and they stuck to the original budget perfectly.
After struggling with another contractor, I brought in Built By Pros for a triplex conversion in Etobicoke. The quality difference was night and day; they fixed existing structural issues and installed proper fire separation that the previous guys ignored. Their design for the third-story addition is the highlight of the neighborhood now. They integrated modern glass railings and large windows that flooded the units with light, making it very easy to find high-quality tenants quickly.
