Multiplex Conversions and New Builds
Turn existing homes into multiple self-contained units. This can be done by dividing the existing home, adding storeys with an addition, or increasing the footprint with an extension. Multiplexes can also be entirely new from the ground up.
Laneway and Garden Suites
Convert your unused garage or backyard to extra living space or a rental unit.
Commercial To Residential Conversions
Repurpose vacant commercial properties into multiple self-contained residential units.
Renovations
Give new life to existing spaces by overhauling the interior and exterior. Renovations modernize your property and add lasting value.

faq
Here are some of the questions we get asked most often.
Up to four units are permitted as-of-right on any residential lot city-wide. Up to six units are permitted as-of-right if your property is in one of the nine sixplex wards. This includes eight wards in the Toronto and East York district plus Ward 23, Scarborough North. Everywhere else remains capped at four.
No, in most cases. A compliant multiplex needs no rezoning, no Official Plan amendment, and no public meeting. It goes straight to a building permit. A variance is only needed if your plans exceed zoning limits like height, setbacks, or lot coverage.
Toronto has relaxed parking requirements for multiplexes as part of its zoning changes, reflecting a broader push toward transit-oriented, walkable development. Parking is often not the limiting factor it once was. Lot width, depth, and servicing tend to matter more.
The short answer is yes. Toronto has steadily been removing development charges from small-scale housing for years. All units up to a fourplex have been exempt from development charges since 2022. In 2025, the City expanded that exemption to cover all units up to a sixplex.
In most cases, yes. However, CMHC offers a free Housing Design Catalogue that features over 50 standardized, near-permit-ready designs, ranging from duplexes to sixplexes and laneway and garden suites, that were developed by architects and engineers to meet regional building codes. These can reduce design costs and timelines, but still require an architect to adapt the designs to your specific lot.
Yes. CMHC’s MLI Select program offers up to 95% loan-to-value financing and extended amortization for purpose-built rental properties with a minimum of five units. Laneway and garden suites are included in the unit count. So a fourplex plus a laneway or garden suite would also qualify.
It depends on the scope of the specific project. Factors like unit count, whether it’s a conversion or new build, and permit complexity all affect the timeline. Time of year also plays a role, as winter construction tends to move much slower than projects that run through the spring, summer, and fall.
Yes, conversions are one of the most common options. However, the existing structure must be strong enough to support the new layout. In some situations it may be too expensive to salvage the existing structure and might be more cost effective to just build a new structure entirely.
