New Parking Requirements

Bookmark and Share

New parking requirements for multi-dwelling developments went into effect May 10, 2013. Previous regulations did not require off-street parking in some commercial zones and on sites that are well-served by transit. The new requirements apply to all multi-dwelling developments with over 30 units outside of plan districts without parking minimums (e.g. Central City, Northwest, Gateway and East Corridor).

New Parking Requirements for Multi-Dwelling developmentsThe new multi-dwelling residential parking requirements are:

  • One space per five units for developments with 31-40 units,
  • One space per four units for 41-50 units, and
  • One space per three units for 51 or more units.

(All fractions for minimum requirements round up to the next whole number.)

The code change also includes additional options for using car-sharing and bike-sharing facilities to reduce the number of off-street parking spaces. Use of all exceptions is capped at 50 percent of the required parking spaces. Any additional reduction in the number of parking spaces will need to be approved through a Type II Adjustment land use review. Loading spaces will be required when more than 40 units are proposed. Provisions for the size for long-term bike parking spaces, clarification of transit street main entrance requirements and joint use of residential parking spaces are also part of the code amendment package.
