What can you build here?
Lot dimensions: 11.1 m x 35.0 m (36'-5" x 114'-10")
A fourplex is as-of-right on nearly any detached lot in the GTA, and many go further, a sixplex in the right ward, a garden suite, or a two-lot severance. Whether the numbers work comes down to the zone, the overlays, and the parcel, which is exactly what a TESA development read tells you. Get one on this lot before it goes.
