If you meet the following rules for your district, you can apply for a building permit.  If you do not meet the rules, you need to apply for a development permit AND a building permit. Be sure to review the following rules for your district AND the building permit requirements.

There must not be more than one suite located on a property.

Please identify the following on your site plan:

  • Property width as it may affect maximum suite area.

Parking

  • The minimum number of parking stalls provided on the property is calculated based on the sum of all units and suites at a rate of 0.5 stalls per unit or suite. This number is always rounded up to the next whole number. For example – a townhouse with 3 units and 2 suites would require 3 parking stalls [ (3+2) x 0.5 = 2.5 -> 3.0).
  • Parking stalls must meet the following minimum dimensions:
    • 2.5 m (8'3") x 5.9 m (20') when not abutting a structure (like a house or garage)
    • 2.85 m (9'5") x 5.9 m (20') when abutting a structure on one side
    • 3.0 m (9'10") x 5.9 m (20') when abutting a structure on both sides

Mobility storage locker

  • A mobility storage locker is a secured location with grade access for the purpose of storing bikes, including heavier and large cargo and electric bikes, mobility scooters, strollers, etc.
  • The minimum number of lockers is calculated based on the sum of all units and suites, less the number of private garage parking stalls provided, at a rate of 0.5 stalls per unit or suite. For example, a 4-unit town house with two suites and three parking stalls an enclosed garage would require 2 mobility storage lockers [(4+2-3) x 0.5 = 1.5 -> 2.0]

Bicycle parking stalls

  • 1 bicycle stall is required for each unit or suite, where that unit or suite is not provided a parking stall in a garage or mobility storage locker.

Amenity space

  • Each suite must have outdoor amenity space. Amenity space can be common, private or a combination of both and must be labelled on the required plans.

Floor area

Note: Required floor area may be relaxed to a maximum of 10 per cent through development permit application.

There must not be more than one suite located on a property.

Please identify the following on your site plan:

Parking

  • The minimum number of parking stalls provided on the property is calculated based on the sum of all units and suites at a rate of 0.625 stalls per unit or suite. This number is always rounded up to the next whole number. For example – a development with 3 units and 3 suites would require 4 parking stalls [ (3+3) x 0.625 = 3.75 -> 4.0) ]
  • Where a parcel is located within 600 metres of an LRT station; 400 metres of a BRT station; or 200 metres of other bus service on the Primary Transit Network, the required parking rated is reduced by 25 per cent. Taking the example above, the final parking requirement would be 3 parking stalls [ 3.75 – (3.75 x 0.25) = 2.81 -> 3.0 ]
  • Parking stalls must meet the following minimum dimensions:
    • 2.5 m (8'3") x 5.9 m (20') when not abutting a structure (like a house or garage)
    • 2.85 m (9'5") x 5.9 m (20') when abutting a structure on one side
