Transform your multi-unit property with custom spatial design for maximum rental yield.



We handle the complex North York zoning regulations and building codes to ensure your multi-unit conversion is 100% legal. This avoids future fines and ensures smooth property inspections during the sale or rental process.
Every design choice is made with your return on investment in mind. We prioritize durable materials and layout optimizations that directly correlate to higher monthly rental rates in the North York market.
Our construction process utilizes advanced fire-suppression materials and soundproofing technology. This creates a safe, quiet environment for different households living under the same roof, minimizing resident conflicts and liability.
Before any design starts, we analyze your property's specific North York zoning to ensure a multi-unit conversion is permitted. This prevents wasting money on designs that the city will eventually reject. We look at lot coverage, setbacks, and density limits as the first step of our professional service.
Our designers create detailed floor plans that maximize rental income while maintaining high living standards. We focus on 'dead spaces' to integrate storage or laundry, ensuring every square foot is functional. This phase involves deep collaboration to match your investment goals with the architectural possibilities.
We navigate the bureaucratic layers of the North York building department and Committee of Adjustment if variances are needed. Our team prepares all necessary technical documentation, from HVAC heat loss calculations to fire safety plans. This stage is critical for ensuring the longevity and legality of your property investment.
During construction, we employ specialized trades familiar with multi-family requirements, such as fire-rated plumbing and electrical segregation. Daily supervision ensures that all work meets the documented design and the strict Ontario Building Code. We maintain a clean work site to minimize disruption to the neighborhood during the transformation.
North York parking requirements vary depending on the specific neighborhood and the number of units. Generally, the city requires a minimum number of off-street parking spots per dwelling unit, though some areas may allow for reductions if the property is near transit hubs like Finch or Sheppard stations. We conduct a preliminary bylaw review for every project to ensure your site plan can accommodate the necessary parking without violating green space minimums.
Costs vary significantly based on the existing structure's condition, but many North York conversions range from $100,000 to over $250,000. Key price factors include required electrical panel upgrades, separate HVAC ductwork, fire-safe ceiling assemblies, and the installation of secondary kitchens and bathrooms. We provide a detailed, itemized quote that breaks down these costs so you can accurately calculate your potential rental yield.
Yes, our team manages the entire process from initial CAD drafting to final city inspection. This includes hiring structural engineers for any load-bearing modifications and submitting architectural drawings to the North York building department. We act as your representative throughout the process, ensuring all technical requirements like MEP (Mechanical, Electrical, Plumbing) plans are professional and approved.
We use a multi-layered approach to sound attenuation, involving Roxul Safe'n'Sound insulation, resilient channels to decouple the drywall from the floor joists, and often double layers of Type X fire-rated drywall. We also pay special attention to sealing air gaps and using acoustic caulking around electrical boxes and plumbing stacks. This high-standard approach ensures that impact and airborne noise are significantly reduced between the upper and lower units.

Learn MoreBuilt By Pros converted my North York bungalow into a legal duplex over a six-month period. Ricardo and his team were incredibly professional, handling the difficult plumbing upgrades required for the second kitchen in the basement. The soundproofing between the floors is remarkable; I can barely hear the tenants upstairs. Their attention to detail on the new side entrance made the units feel completely independent.
We hired Suzanne to help us optimize a triplex in Willowdale. She found space for a common laundry area and bike storage that we hadn't even considered. The project was completed on schedule, and the modern finishes they suggested allowed us to rent out the units within one week of listing. It’s hard to find contractors in the GTA who actually stick to their timelines like they did.
As a first-time investor in North York, I was worried about the permit process for a multi-unit build. The team at Built By Pros handled everything with the city, and the final results exceeded my expectations. They used high-quality quartz for the kitchens and durable vinyl flooring that looks expensive but is very tenant-proof. I will definitely be using them for my next property acquisition.
