Transform your Richmond Hill property into a high performing multi unit investment today.
We focus on high-impact upgrades like custom cabinetry and modern lighting that directly increase rental income in Richmond Hill. Our team analyzes local market trends to ensure your renovation costs translate into significant property appreciation and monthly cash flow. We help you avoid over-improving while ensuring the unit remains competitive.
Navigating Richmond Hill's specific secondary suite policies can be daunting for many homeowners. We manage the entire administrative process, from obtaining zoning variances to securing final building permits from the York Region authorities. This ensures your multi-unit property is fully legal, insurable, and safe for all occupants.
The number one complaint in multi-unit living is noise transmission between floors. We utilize advanced sound-dampening insulation and resilient channeling to create a quiet environment for every tenant. This technical precision reduces tenant turnover and minimizes conflicts, making property management much easier for the owner.
Our first step is to visit your Richmond Hill property to assess the structure and review local zoning bylaws. We identify any potential hurdles with the Ontario Building Code or municipal regulations early on to avoid costly delays. This step ensures that your vision for a multi-unit space is actually achievable and legal.
We create detailed architectural and engineering drawings that maximize the available square footage for your new units. Our team handles the entire submission to the Richmond Hill building department, responding to any requests for information from city planners. This ensures all life-safety elements like fire separations are correctly documented.
Before the finishes go in, we perform critical structural work and update the plumbing and electrical systems to support multiple households. This often involves upgrading the water service or installing a second electrical meter to make utility management easier. This 'behind the walls' work is vital for long-term property durability and tenant safety.
The final stage involves installing high-quality materials that stand up to rental wear and tear while looking modern and attractive. We coordinate all mandatory inspections with the city of Richmond Hill to ensure the project meets every standard for occupancy. Once we receive the final sign-off, your property is ready to generate income.
Most residential zones in Richmond Hill allow for secondary suites, but they must comply with specific criteria regarding lot size, parking, and fire safety. The property must be your principal residence in some cases, and it must be registered with the city. We provide a preliminary consultation to check your specific address against the latest municipal zoning bylaws.
Costs vary significantly based on the existing state of the property and the level of finishes. Generally, a legal basement suite conversion starts around $80,000 to $120,000, while more complex multi-story optimizations can be higher. Factors like plumbing stack relocation, egress window excavation, and electrical upgrades are the primary drivers of the budget.
A standard multi-unit optimization project typically takes 3 to 5 months from the initial design phase to final completion. This includes 4-6 weeks for permit approval from the City of Richmond Hill and roughly 12-16 weeks for the construction phase. We provide a detailed project schedule at the start to ensure you can plan your rental listing accordingly.
Richmond Hill generally requires at least one dedicated off-street parking space for the secondary unit in addition to the spaces required for the primary dwelling. Tandem parking (one car behind another) is often permitted, but this must be verified during the permitting stage. We help design landscaping and driveway extensions that meet these requirements without sacrificing curb appeal.

Learn MoreBuilt By Pros Inc. helped us convert our large basement in the Jefferson side of Richmond Hill into a legal two-bedroom suite. The project took exactly 10 weeks, and the craftsmanship on the new kitchen was outstanding. Suzanne handled all the tricky permits with the city, which was a huge relief for us. We now have a high-quality rental unit that pays for half our mortgage.
We wanted to optimize our multi-unit townhouse exterior and interior to lure better tenants. Ricardo's team replaced the old flooring with durable LVP and completely redesigned the shared entrance for better privacy. They worked through a cold Richmond Hill winter to finish on time, and the glass railings they installed in the stairwell really modernized the whole space. Highly recommend their professional approach.
After interviewing four contractors, we chose Built By Pros for our multi-unit optimization project in Mill Pond. They were the only ones who truly understood the soundproofing requirements needed for a legal duplex conversion. The project was over 1,200 square feet and included a full electrical panel upgrade to 200 amps. The final result exceeded our expectations and passed all inspections on the first try.
