Transform your Mississauga property into a high yielding multi unit residential masterpiece.
We focus on designs that specifically increase rental yield and property value in the Mississauga market. By using professional CAD layouts, we maximize every inch of floor space to accommodate premium features that attract high-paying tenants. Our strategy involves balancing upfront construction costs with long-term rental income potential to ensure your investment pays off quickly.
Navigating Mississauga's building department can be daunting, but we handle all the paperwork for your multi-unit conversion. From initial zoning reviews to final occupancy permits, we ensure every aspect of the project is 100% legal and up to code. This protects you from future city orders and ensures your insurance remains valid for a multi-residential property.
We utilize advanced noise-mitigation technologies, including resilient channels and specialized acoustic insulation, to create peaceful living environments. In multi-unit setups, privacy is the top tenant requirement, and our methods significantly reduce the transfer of foot traffic and vocal noise. This leads to higher tenant retention and fewer management headaches for Mississauga landlords.
We begin by assessing your Mississauga lot and structure against local zoning bylaws to determine the maximum unit potential. This step prevents wasted investment on non-compliant designs and pinpoints necessary utility upgrades early. We provide a preliminary budget so you can understand your projected ROI before signing a contract.
Our internal design team creates CAD drawings that optimize interior flow while meeting all Ontario Building Code safety requirements for multi-unit dwellings. We manage the entire submission to the City of Mississauga, handling any revisions requested by the building department. This ensures that when construction starts, every change is fully legal and documented.
During the main construction phase, we focus on the core infrastructure, including fire separations, soundproofing, and updated electrical panels for multiple meters. We also handle specialized tasks like basement underpinning if more height is needed to meet Mississauga's legal standards. This stage is critical for the longevity and safety of the rental units.
We install high-durability, high-aesthetic finishes that stand up to the Mississauga rental market's demands. Once the work is complete, we coordinate all city inspections to ensure your multi-unit property receives its final occupancy permit. We don't consider the job done until your property is legally recognized and ready for tenants.
Under the current Mississauga Official Plan and Ontario's Bill 23, most residential lots now allow for up to three units—the primary residence and two additional residential units (ARUs), such as a basement apartment and a garden suite. However, specific lot sizes, parking requirements, and setbacks can still impact your specific project. We conduct a thorough zoning analysis at the start of every project to determine local limitations and maximize your property's potential.
Mississauga adheres to the Ontario Building Code, which generally requires a minimum ceiling height of 6 feet 11 inches (2.1 meters) over at least 75% of the required floor area. If your basement is currently too shallow, we offer underpinning and benching services to lower the floor, ensuring your unit is fully legal and comfortable. This structural work is a common part of our space optimization process in older Mississauga neighborhoods with low-clearance foundations.
Yes, to meet fire safety and privacy standards, each unit must have its own dedicated means of egress. One of these must lead directly to the exterior of the building. Our team specializes in designing creative entrance solutions, such as side-door walkouts or integrated stairwells, that comply with Mississauga building codes while maintaining the property’s aesthetic. Providing separate entrances is not just a legal requirement but also a major factor in tenant desirability and rental pricing.
For a standard basement-to-legal-suite conversion in Mississauga, the construction phase typically lasts between 3 to 5 months. However, the pre-construction phase, including architectural drawings and City of Mississauga permit approvals, can add another 2 to 4 months to the timeline. We provide a detailed project schedule during our consultation and use aggressive project management to ensure we meet our deadlines, minimizing the time your property is dormant during construction.

Learn MoreBuilt By Pros Inc. helped us convert our large bungalow in the Applewood area into a triple-unit investment property. Ricardo and his crew were spectacular, managing the structural changes and fire separation requirements flawlessly. The project took about six months from the first drawing to completion, and we were impressed with how they maximized the basement footprint to include two full bedrooms. The finish quality, especially the custom cabinetry and vinyl flooring, is top-tier and helped us find tenants within a week of listing.
After researching several contractors for our garden suite project, we chose Built By Pros for their deep knowledge of Mississauga's new ARU bylaws. Suzanne's design for the 600 sq ft unit was incredibly efficient, making the space feel much larger than its footprint suggested. The team navigated the permit hurdles with the city expertly, even when we hit a snag with the sewer lines. They completed the project on time and within 5% of the initial quote, which is rare in this industry.
I hired Built By Pros Inc. to optimize a multi-story townhome for a dual-rental configuration. They managed to add a secondary kitchen and a dedicated entrance without ruining the architectural flow of the building. The use of high-efficiency HVAC units for both suites has kept our utility costs low during the Mississauga winter months. It was a 4-month project that completely transformed my financial outlook for this property. Highly recommended for any serious real estate investor.
