Detached Garden Suites

Detached Garden Suites provide an important form of affordable housing in the City of Maple Ridge that benefits both renters and homeowners. A detached garden suite (or DGS) is not intended to be a second principal house on the one family lot but is rather meant to be detached, accessory and subordinate in nature to the main house.

What is New?

At the April 26, 2022 Council Workshop, Council received a report that presented eleven accessory dwelling unit (such as secondary suites) regulatory options that would support affordable housing options by expanding the rental stock in a community where infrastructure and amenities, such as schools, parks, and shopping/services, already exist. At this meeting, Council directed staff to bring forward a report that provides detailed information and description of the amendments for ten of the eleven recommendations. The ten recommendations are:

  1. Removal of the maximum and minimum gross floor area requirement for secondary suites 
  2. Development of ‘Alternate Compliance Methods for Alterations to Existing Buildings to Add a Secondary Suite’ in the BC Building Code 
  3. Options to potentially allowing secondary suites in all single-detached residential zones 
  4. Permitting secondary suites in ground-orientated duplexes and townhouses 
  5. Permitting secondary suites and detached garden suites on the same lot in the Agricultural Land Reserve 
  6. Allowing flexible siting of a detached garden suite on a lot 
  7. Removal of the minimum gross floor area requirement for detached garden suites 
  8. Permitting larger detached garden suites in specific residential zones 
  9. Permitting secondary suites and detached garden suites on the same lot in all residential zones 
  10. Development of program, for council consideration, that would create “pre-approved” building plan templates for detached garden suites

Council also directed that the current bylaw enforcement related to the issue of unregistered secondary suites be held in abeyance while the work to expand the secondary suites and detached garden suites program is underway. At this workshop meeting, Council directed staff to not bring forward a report with potential amendments to permit lock-off suites in apartments and stacked townhouses.

Business Licence Requirements


A Business Licence is required if there are two rental units on the property. This means if the single detached home is being rented and there is a detached garden suite on the property that is also being rented, the property owner must have a business licence in order to rent both dwellings.

There is a business licence fee for rental units and there is a one-time Application Review Fee of $500. To obtain a Business Licence, please visit: https://www.mapleridge.ca/191/Business-Licensing
