How Many Units Can I Add to My House in Ontario?

A common question among investors is, how many units can I add to my house in Ontario? Thanks to recent provincial legislation aimed at increasing housing supply, homeowners are generally permitted to have up to three residential units on a single property. This typically includes the main house, a basement apartment, and a detached garden suite or laneway house. However, local municipal zoning bylaws regarding parking and lot coverage still apply.
