Multiplex Development
Turn One Property Into a Portfolio
A multiplex is a residential building containing two to four self-contained dwelling units on a single lot. Duplexes, triplexes, and fourplexes offer a proven path to building rental income while contributing to neighbourhood housing supply.
In 2023, the Province of Ontario passed Bill 23 (More Homes Built Faster Act), which allows up to three units as-of-right on most residential lots across the province. Many municipalities, including Toronto, have expanded this to permit up to four units without rezoning or minor variance applications.
