Can You Build on Your Lot?
Can you build one on your lot?
Toronto has allowed laneway suites since 2018 and garden suites city-wide since 2022 — but not every lot qualifies. Eligibility hinges on a handful of specifics: emergency-access distance from the street, rear and side setbacks, the size and height of the suite relative to your lot, protected trees, and how water, sewer and hydro can reach the new building.
That's why every CNB project starts with a free feasibility check. Send us the address, and we confirm what's actually buildable on your property — before you spend anything on design.
Rules summarized as of 2026 — we verify what applies to your exact address during the free check.
Garden suite vs laneway house
For lots that back onto a public laneway. The suite fronts the lane, and parking or garage combinations are possible.
No laneway needed — a detached backyard home on a regular residential lot, sized to your yard and setbacks.
Both are self-contained homes with kitchen, bath and laundry — same permits logic, same team, same fixed price.

What homeowners ask before hiring us
Access. A laneway house sits on a lot that backs onto a public laneway and fronts the lane; a garden suite doesn't need a laneway at all. Otherwise the idea is the same — a detached, self-contained second home on your lot, with its own kitchen, bath and laundry.
No. Garden suites are allowed city-wide where the lot meets access, setback and servicing rules — no laneway required. The free feasibility check answers this definitively for your address.
It depends on your lot size, setbacks and height limits. Typical builds range from compact studios to two-storey two-bedroom homes. At feasibility we show you the maximum envelope your specific lot allows, so you design to real numbers.
Feasibility takes days. Design and approvals take months, and construction takes months more depending on the size of the suite. You get a dated schedule together with the fixed-price quote — a commitment, not an estimate.
Yes — drawings, permits, tree and servicing reviews, all submissions and all responses to city comments. One in-house team owns the approvals from start to finish.
If the suite is part of a bigger play, see our fourplex & multiplex conversions — a garden suite can be the 5th door on a multiplex property, run as one coordinated project.
