BUILDING LENGHT in deep lots for Triplex and Fourplex ( Toronto )

Building Length on Deep Lots

Regulation 10.20.40.20(3)

(3) Maximum Building Length for a Duplex, Triplex, or Fourplex with Specific Lot Frontage and Depth:

• Despite regulation 10.20.40.20(1), in the RD zone, a duplex, triplex, or fourplex can have a maximum building length of 19.0 meters if the lot:
  • (A) Has a lot depth of 36.0 meters or greater and a lot frontage of less than 10.0 meters; or
  • (B) Has a lot depth of 40.0 meters or greater and a lot frontage of 10.0 meters or greater.

Additional Information:

• While a detached house with an extension in the RD and RS zones is allowed a 19-meter building length, the extension is limited to one story in height, 50% of the building's width, and must have 3-meter setbacks from side lot lines. Multiplexes do not have these restrictions.

Tip:

• The required lot sizes for the 19-meter length permission ensure that the lot is big enough for the multiplex to meet minimum setback and lot coverage requirements, despite the extended length.
