Laneway and garden suites are self-contained residential units built in the backyard of an existing property. Toronto has aggressively promoted these units to increase housing supply, and 2025–2026 zoning updates have made them easier to build than ever. If your property qualifies, a suite can generate rental income, house family members, and increase your property value.
Laneway suite: Built on a lot that borders a public laneway. The suite typically faces the laneway and uses it for primary access. It remains legally tied to the main property.
Garden suite: Built on a lot without laneway access. Accessed via a clear pedestrian path from the street, alongside the primary residence, into the backyard.
Both are independent, self-contained units with their own kitchen, bathroom, and entrance. Learn more about our laneway suite construction services or our dedicated garden suites in Toronto page.
Toronto updated its laneway and garden suite zoning in 2025 through By-laws 847-2025 and 849-2025, following provincial regulation 462/24. Both suite types are now permitted as-of-rightin most residential zones (R, RD, RS, RT, and RM designations). "As-of-right" means if your design meets the predefined parameters, the City must issue a building permit — no rezoning or Committee of Adjustment hearing required.
| Zoning Metric | Laneway Suite | Garden Suite |
|---|---|---|
| Fire / emergency access | Entrance within 45 m of a public street via the laneway, or 90 m through the main property | Clear, unobstructed path at least 1.0 m wide from street to suite (45–90 m max travel distance) |
| Separation from main house | Min. 4.0 m if suite ≤ 4.0 m tall; min. 7.5 m if taller | Same as laneway |
| Maximum height | Up to 4.0 m (one storey) or up to 6.0–6.3 m (two storeys), depending on separation distance | Same as laneway |
| Rear yard setback | Min. 1.0 m from laneway lot line | Min. 1.5 m from rear lot line |
| Side yard setback | 0.0 m allowed if no windows/doors on that wall | Greater of 1.5 m or 10% of lot frontage |
| Soft landscaping | 85% of space between main house and suite must be permeable planting (lots > 6 m wide); 60% for lots ≤ 6 m | Similar minimums for stormwater management |
| Lot coverage | Max 45% for all buildings on the lot | Same |
| Parking | One parking space per unit | Same |

The City now offers free pre-approved building plans through its Made in Toronto program. These comply with the Ontario Building Code and can significantly reduce architectural fees and speed up permit approvals. You still need a building permit, and the plan must be adapted to your specific lot placement.
Development charges for laneway and garden suites can be deferred interest-free for 20 years — a significant financial benefit that reduces your upfront costs.
| Suite Type | Cost per Sq Ft | Typical Total |
|---|---|---|
| Garden suite | $400–$550 | $350,000–$600,000 |
| Laneway suite | $450–$600 | $350,000–$600,000+ |
Costs depend on foundation requirements, utility connections, interior finishes, and architectural complexity. Premium suites in Forest Hill, Rosedale, and Lawrence Park include higher-end finishes at the upper end of these ranges. Using the City's pre-approved plans can reduce design costs. See our cost calculator for a detailed breakdown.
Despite the high upfront investment, the return profile is strong because you already own the land:

Book a Free ConsultationToronto's Private Tree By-law protects any tree with a trunk diameter of 30 cm or more. Removal without a permit carries fines up to $100,000 per tree. If your suite construction encroaches on protected root zones, you will need an ISA-certified arborist report. Contact Urban Forestry early in the planning process.
Start by confirming whether your property qualifies — check your zoning designation and whether your lot borders a public laneway. The City's interactive zoning map is the best starting point.
