Accessory Dwelling Units

What is an Accessory Dwelling Unit?

Accessory Dwelling Unit (ADU) is a collective term used for various types of suites that have their own entrance, kitchen, sleeping and bathroom facilities, including: 

Why Would I Want an ADU? 

Mortgage helper: With rising housing costs, purchasing a house with an ADU or adding an ADU can make it easier to facilitate the ownership of entry-level housing.
Aging in place: Owners on a limited income can remain in their own homes longer by renting an ADU. Also, having someone close by can help to provide a sense of security.
Deductible expenses: There are a number of expenses that can be deducted against rental income, including 
advertising, insurance, interest, repairs and maintenance, and utilities.
Allowing families to stay together: An accessory suite may provide a home for an adult child, elderly parents, or a disabled relative.

How Do I Know if ADUs are Allowed in my Area?

The Land Use Bylaw allows for accessory dwelling units within all residential land use districts with the exception of:

  • R3 Residential Comprehensive Multiple Unit District
  • R5 Residential Apartment District
  • MHP Residential Manufacted Home Park District 
  • EHD Employee Housing District

As an incentive to encourage the development of ADUs in these districts, Detached Dwellings with an ADU are now listed as a permitted use. As a result, if a Detached Dwelling with an ADU is capable of meeting all the requirements of the Land Use Bylaw, a Development Permit will not be required and can therefore be approved through the Building Permit process. 

One on-site parking stall must be provided per ADU.
