What’s Changed?

City Council approved changes to the Zoning Bylaw regulations governing the height and grade of buildings with the adoption of Bylaw 16733 and Bylaw 17062 on July 8, 2015. Changes apply to every standard zone and overlay in the city and will be implemented as property owners and builders come forward with development applications. 

The changes are part of ongoing work to align Zoning Bylaw regulations with consumer preference for more choice in residential housing. Additional height regulation changes are slated to go before City Council later this year.

To help reduce complexity and increase clarity and understanding of the changes, the approved height and grade regulation changes have been grouped into two parts. 

Part 1 - Bylaw 16733 (July 8, 2015) 

Bylaw 16733 makes the following regulation changes:

  • Removes reference to storeys as a measure of maximum height, increasing flexibility in the internal layout of buildings.
  • Makes most walkout basements and drive-under garages Class A developments, allowing them to be built without special permission.
  • Housekeeping items such as making sure that defined terms are used properly and consistently, and images are updated to reflect changes identified.

Previously proposed changes to the Special Information Requirement regulations and the Mature Neighbourhood Overlay (MNO) are no longer included as part of Bylaw 16733.  Changes to the Special Information Requirements regulations were addressed in a separate bylaw that was approved by City Council on July 6, 2015.  

Part 2 - Bylaw 17062 (July 8, 2015)

Bylaw 17062 makes the following regulation changes:

  • Simplifies the definition of height by relocating the regulations from the definition to Section 52.
  • Provides specific guidance for measuring height of buildings based on roof type (eg. flat, gambrel, gable, mansard, etc).
  • Adds an additional method for calculating average grade for walkout basement developments.
  • Increases the height of multi-tenant buildings from 14 metres to 14.5 metres for those with flat roofs and 16 metres for those with pitched roofs in select zones and overlays. This helps align the bylaw with current construction practices, such as the additional height required for open-webbed floor trusses, steeper-pitched roofs, engineered I-beams, and more challenging building sites.
  • Housekeeping items such as reorganizing and renumbering of Section 52.
