Client Success Story
Nima, as a project manager in Renotec, came here from the beginning, gave us his advice, helped us move forward through the process, and converted our 1920s home in East York into a legal duplex. The whole team handled zoning approvals, permits, and construction properly. Completed in 16 weeks, we now have two modern units, each with its own separate entrance and meters. Our rental income has increased significantly, even for the rent they helped us with the process, and we highly recommend them to all our neighbours and family friends.

General Questions About Home addition
1.What is a multiplex conversion?
Upgrading a single-family home into more legal rental units, such as duplexes or triplexes, to increase rental income and property value. The zoning bylaws change regularly, and Toronto encourages homeowners to follow these options to meet housing needs. Before starting, check the ROI to identify the best approach. When converting your home to a multiplex, consulting experienced professionals is necessary to deciding on the cap rate, which helps you make wise decisions more easily.
2. Are permits required?
We explain the permit process, the fees, and development charges, or even the rebate you can get, but all multiplex conversions must follow Toronto and GTA zoning and building codes. Attempting to proceed without permits or city coordination can create legal issues for both homeowners and builders.
3. How long does a multiplex conversion take?
Every single project is different. We will create a Gantt chart for our customers, typically taking 4 to 9 months, depending on project complexity and permitting. We recognize that the interest rate during the construction process is significant for the customer. Timing is the most critical item, and New rules and regulations help homeowners understand city allowances, making the process smoother.
4. How much does it cost?
Projects usually range from $150,000 to $500,000, depending on size and scope. Experienced architects and planners are recommended, especially for heritage homes, basements, underpinning, and accessibility, which can affect costs. Analyzing budget and cost is different for each project, but we will help you achieve the best return on your investment.
5. Can I live in my home during construction?
This depends on the extent of renovation. Our team advises on the best options, but due to safety and the scope of work, it is generally not recommended.
6. Can I finance my multiplex conversion with CMHC loans?
Yes, many projects qualify under CMHC’s RCFI and MLI programs. We recommend consulting an experienced loan professional to explore all options and interest rates. CMHC offers up to 95% financing on construction costs with low interest, provided you have a strong portfolio.
7.How long does a multiplex conversion take to complete?
The typical project timeline is 4–8 months, which includes both permitting and construction phases.
8.Are there any hidden costs?
No. We provide transparent quotes with detailed estimates upfront, so you know exactly what to expect before starting your project. To prevent any future conflict, we will provide you with a clear contract and detailed scope of work.
