Toronto Multiplex Zoning, Permits & Feasibility Analysis
A multiplex is a residential building containing 3 to 6 self-contained dwelling units on a single lot.
In Toronto, multiplex feasibility depends on zoning, Major Street eligibility, lot dimensions, setbacks, angular planes, servicing, and existing building conditions.
Check this against your actual Toronto property.
