Duplex, Triplex & Fourplex Regulation Changes
As Toronto’s population continues to grow, the city is embracing multiplex conversions to expand housing supply across Canada’s largest urban market. The City of Toronto has approved a city-wide zoning amendment that allows multi-unit residential homes in all residential zones.
In addition to these changes, multiplex development charges are now being waived—even if owners choose to convert or build units over time. This creates a powerful opportunity to transform a single-family home into a duplex, triplex, fourplex, or more—while significantly increasing your property’s rental value.
Take advantage of this opportunity by contacting SL Designs today to begin the evaluation process and understand how these regulations can work in your favor.
