Multiplex FAQ

A multiplex is a residential building with two to six self-contained units on one lot, for example a duplex, triplex, fourplex or sixplex. Each unit has its own kitchen, bathroom and entrance, and the units share the lot.

Fourplexes are generally permitted in residential neighbourhoods across Toronto. Sixplexes are currently permitted only in certain wards. Lot size, frontage, height, setbacks and heritage status all matter, so every address needs its own zoning check. (TODO verify against the City's current by-law.)

It depends on the condition of the structure, ceiling heights, foundation, and how many units you want. Converting is often faster and cheaper per unit; a new build gives you full control of layout and can reach the maximum unit count. A feasibility study compares both with real numbers for your property.

As a rough guide, design and permits take several months, and construction takes several more, depending on scope. We give you a project-specific schedule after the feasibility study. (TODO verify ranges with company project data.)

Costs vary widely with scope, finishes, site conditions and unit count. We do not publish a single number because it would be misleading. The feasibility study gives you a budget range for your specific property.

The City of Toronto has waived development charges for many small multiplex projects and offers a deferral program for qualifying garden and laneway suites. Eligibility rules apply, so confirm with the City for your project. (TODO verify current rules.)

MLI Select is for rental properties with five or more units, so it can apply to some sixplex projects. It rewards commitments to affordability, energy efficiency or accessibility. A mortgage professional can confirm eligibility. (TODO verify.)

Only if your design does not meet the zoning by-law and needs a minor variance. Many projects can be designed to comply as of right, which saves months. We identify this early in the feasibility stage.

Yes. Many owners live in one unit and rent the rest. Financing, tax treatment and insurance differ from a fully rented building, so speak with your lender and accountant.
