Maximum Height of building in Triplex and fourplex (Toronto Area)

Maximum Height of building in Triplex and fourplex 

Determining the Height of a Building (Regulation 10.5.40.10(1)):

• In the Residential Zone Category, the height of a building is measured from the established grade (ground level) to the highest point of the building.

Maximum Height (Regulation 10.20.40.10(1)):

• Maximum Height Allowed:
  • (A) The maximum height allowed for a building or structure on a lot in the RD zone is given by the number (in metres) following the letters "HT" on the Height Overlay Map.
  • (B) If there is no number following the letters "HT" on the Height Overlay Map, the maximum height is 10.0 metres.
  • (C) For duplexes, triplexes, or fourplexes, the maximum height is the greater of:
    • (i) The number (in metres) following the letters "HT" on the Height Overlay Map, or
    • (ii) 10.0 metres.

Tips:

• This regulation ensures that multiplexes (duplexes, triplexes, or fourplexes) are allowed a height of at least 10 metres city-wide, even if the Height Overlay Map shows a lower maximum height.
• If a Chapter 900 exception sets a maximum building height of less than 10 metres for multiplexes, that exception will still apply.

Quick Reference Across All Residential Zones:

• Residential (R): Regulation 10.10.40.10(1)(C)
• Residential Detached (RD): Regulation 10.20.40.10(1)(C)
• Residential Semi-Detached (RS): Regulation 10.40.40.10(1)(C)
• Residential Townhouse (RT): Regulation 10.60.40.10(1)(C)

Additional Tips:

• For sites without a value on the Height Overlay Map, most zones default to a height of 10 metres. In the RM zone, multiplexes on such sites are allowed a height of 12 metres as per Regulation 10.80.40.10(1)(B)(ii).
