Garden suites — self-contained residential units in the backyard of existing homes — became permissible across Toronto in 2022. Here’s the 2026 guide.
Garden suite vs. laneway suite:
Laneway suite: Requires the lot to abut a public lane. The suite faces the lane. Established and popular in older Toronto neighbourhoods.
Garden suite: No lane required. Accessed via pathway through the side yard or along the main lot. Opens up the option to many more properties.
Toronto’s garden suite rules (2026):
- Maximum floor area: 60 sq m + 10% of lot area
- Maximum two storeys (with height limits)
- Minimum access path: 1.5m width
- Rear and side setback requirements apply
- Parking: not required
- Zoning: permitted as-of-right in most Toronto residential zones (verify your specific zone)
Cost (Toronto, 2026):
- Design and permit: $25,000–$50,000
- Construction: $275,000–$450,000
- Total: $300,000–$500,000 for a quality build
The income case:
One-bedroom garden suite in Toronto: $2,000–$3,000/month.
On a $400,000 investment: gross yield = 6–9%.
Plus capital value of the additional structure.
Timeline: 12–18 months from concept to first tenant (design, permit, construction).
