Laneway suite vs garden suite vs rooftop addition — which should I consider?
Answered by AskBaily Editorial · Updated
Short answer
Toronto's Changing Lanes by-law (CPLS) permits laneway suites on lots with a public laneway abutting the rear; typical cost CAD $350K-$550K, 10-18 months timeline. Garden suites (permitted city-wide since 2022) sit in the backyard without requiring a laneway; cost CAD $300K-$500K, 8-16 months. A rooftop third-storey addition typically costs CAD $250K-$450K, 6-14 months, but usually triggers Committee of Adjustment for FSI and height variance. Baily sizes all three at scope review.
