Toronto's 2025 zoning reform made laneway and garden suites as-of-right on roughly 80% of residential lots. We design and build them end-to-end, including pre-approved plans that save $15K–$20K in design fees.
A laneway suite is a detached residential building accessed from a public laneway behind a property. A garden suite is similar, but built on lots without laneway access — typically in the rear yard with side-yard access. Until recently, both required individual rezoning and Committee of Adjustment hearings. As of 2025, neither does in most of Toronto.
Toronto's By-laws 847-2025 and 849-2025 made laneway and garden suites as-of-right (no Committee of Adjustment) on lots meeting basic dimension requirements. The province's setback reforms further expanded eligibility — roughly 80% of GTA single-family lots now qualify. The City also released a portfolio of "Made in Toronto" pre-approved plans, which save $15,000–$20,000 in design fees and shave 6–8 weeks off permit timelines.
Combined with the federal $80,000 Secondary Suite Loan and Toronto's 20-year interest-free development charge deferral, the financial conditions for backyard suites in 2026 are dramatically more favourable than at any point in the last decade.
Current GTA construction costs for laneway and garden suites land at $450–$600 per square foot all-in, with most projects falling between $365,000 and $525,000 total for a 700–900 sq ft suite. The variance comes down to four factors: site complexity (servicing distance, grade, tree protection), suite size, finish level, and whether you use pre-approved plans or fully custom design.
All-in pricing including design, permits, build, financing paperwork, and warranty.
Roughly 80% of single-family lots in Toronto now qualify as-of-right. The key dimensions: minimum 7m of rear lot width for laneway suites, minimum 5m setback from the main house for garden suites, and adequate side-yard access for construction. Use our Lot Eligibility Checker for a quick read, then we confirm exact dimensions during the site visit.
Laneway suites are accessed via a public laneway behind the property — typically in older Toronto neighbourhoods (Trinity-Bellwoods, Leslieville, Riverdale, etc.). Garden suites are built on lots without laneways and accessed via the side yard. Both fall under similar zoning rules now, but garden suites have stricter setback and access requirements.
Typical timeline: 10–14 months from contract signing to occupancy permit. About 4 months covers design and permits (faster with pre-approved plans), 6–8 months is the actual build, and the rest is final inspections and servicing connections. Pre-approved plans can shrink the design phase to about 6 weeks.
In Toronto's core (Leslieville, Riverdale, the Beaches), a 1-bedroom laneway suite typically rents for $2,200–$2,800/month. A well-built 2-bedroom can hit $2,800–$3,500. Suburb pricing is lower — usually $1,900–$2,400 for comparable size. We provide a rental comparable analysis as part of every assessment.
Sometimes. The City's pre-approved plans cover a range of lot widths and configurations, but not every lot fits. We assess this upfront — if your lot needs custom design, we'll tell you, and the pre-approved plan savings ($15K–$20K) won't apply. About 60% of our laneway projects use pre-approved plans.
Toronto's tree protection by-law applies to any tree over 30cm in diameter. We obtain tree protection plans where required. Shadow studies are now only required for suites taller than the standard envelope. Neighbour notification is no longer required for as-of-right suites — though we always recommend a courtesy conversation with adjacent neighbours before construction begins.
As-of-right zoning, $80K federal financing, 20-year DC deferral, and pre-approved plans. We don't know how long this combination will last — but right now, it's real.
