Maximize your property revenue with expert multiplex design and legal unit conversions.



Proud to serve communities throughout Oakville, ON
Every Oakville lot is different, requiring a bespoke approach to unit layout. We create architectural plans that maximize every square inch, ensuring separate entrances and private living areas that attract premium tenants. This custom approach ensures compliance with the specific height and density bylaws of the Halton region.
The Town of Oakville requires detailed documentation for multi-unit conversions, including electrical, HVAC, and fire safety plans. Our team handles the entire submission process, from initial zoning research to final occupancy inspections. This eliminates the stress of navigating municipal bureaucracy and prevents costly delays in your construction timeline.
We don’t just build; we consult on the financial feasibility of your multi-unit project. By analyzing local Oakville rental market trends and construction costs, we help you determine the most profitable configuration for your property. Our goal is to ensure your renovation delivers the highest possible cash flow and equity growth.
We start with a comprehensive site visit to Oakville to assess your property's potential under the latest by-laws. We review lot coverage, existing plumbing lines, and structural capacity to determine if a duplex, triplex, or fourplex is the best fit. This step saves time and money by confirming the project's viability before expensive drawings are made.
Our designers create detailed floor plans that prioritize space efficiency and legal compliance. We coordinate all architectural, mechanical, and structural engineering to meet Oakville's rigid permit submission standards. Having 'permit-ready' drawings is essential for avoiding city back-and-forth and ensuring a fast approval process.
Once permits are in hand, our licensed crews begin the transformation with daily on-site supervision. We manage all trades, from rough-in plumbing for multiple kitchens to the installation of fire-rated separations. We maintain constant communication with Oakville's building inspectors to ensure every milestone is signed off without delay.
We complete the project with a rigorous quality check and a full walkthrough with you. We handle the final inspections required for the 'Notice of Completion' from the town and hand over all warranties and documentation. You are left with a fully legal, move-in-ready property that is ready to start generating income.

Learn MoreWe worked with Built By Pros to convert our older bungalow in Kerr Village into a legal triplex. The team was exceptional at handling the unexpected structural issues we found with the foundation and managed the entire Oakville permit process seamlessly. The project was completed in just six months, and we were able to rent out all three units immediately. The quality of the fire separation and soundproofing was a major selling point for our new tenants.
Transforming my carriage house into a dual-suite rental was a daunting idea until I met Suzanne and Ricardo. They respected the heritage aesthetic of Old Oakville while modernizing the interior with high-end kitchens and separate HVAC units. Their attention to detail on the electrical upgrades and the exterior stone work was incredible. I highly recommend them for anyone looking for a stress-free conversion experience.
I hired Built By Pros for a basement conversion and addition in Glenorchy to create a multi-generational living space. The design maximized the natural light in the lower unit, and the custom finishes mirror the luxury feel of the main house. They navigated the city's strict lot coverage and parking rules without any issues. It took eight months from initial design to move-in, exactly as promised in our original contract.
