Garden suites - also called detached accessory dwelling units or backyard suites - are now permitted on most single-family and duplex lots in Victoria, Saanich, Langford, and across Greater Victoria following provincial zoning changes in 2023-2024. If you have a large enough lot, you can build a self-contained, rentable dwelling unit in your backyard. Here is the complete guide.
What Is a Garden Suite?
A garden suite is a smaller, self-contained home built on the same lot as a primary residence. It has its own entrance, kitchen, bathroom, and sleeping area. Garden suites are typically 400-800 sq ft and are separate from the main house - either detached or connected by a breezeway. They are distinct from basement suites, which are attached.

Rental Income Potential in Victoria
Victoria has one of the lowest rental vacancy rates in Canada, consistently below 2%. A well-built 1-bedroom garden suite in a desirable neighbourhood (Fairfield, Fernwood, Saanich) can realistically rent for $1,800 to $2,500 per month. A 2-bedroom can reach $2,400 to $3,000/month. At these rates, a $250,000 investment can pay itself back in 8-12 years while appreciating with the property.
Financing a Garden Suite in Victoria
- ✓HELOC: A home equity line of credit is the most common financing tool. With Victoria home values averaging $850,000+, most homeowners have significant equity to draw from.
- ✓CMHC MLI Select: For purpose-built rental housing, CMHC offers insured financing at favourable rates. A garden suite built with the intent to rent may qualify.
- ✓BC Housing Programs: Check with BC Housing for current homeowner renovation programs that may apply to secondary and garden suite construction.
- ✓Refinance: Some homeowners refinance their primary mortgage at build completion when the appraised value reflects the new suite.
