What could be built at 20 Thelma Ave
The largest filing here created 2 units. Ward 12 is one of the wards where six units are permitted as-of-right, so the ceiling on this street may be higher than what was filed. PlexCheck reads the City zoning stamped at this address, applies the multiplex rules for Old Toronto, and prices the build against CMHC survey rents for the surrounding area.
