Frequently Asked Questions

Toronto's zoning for laneway and garden suites was updated in 2025 (By-laws 847-2025 and 849-2025) following provincial regulation 462/24, making them as-of-right in most residential zones. Key rules include height limits of up to 6.3 m when properly separated, minimum 4 m or 7.5 m separation from the main house depending on height, and one parking space per unit. Laneway suites require your lot to abut a public laneway with a minimum 3.5 m frontage; garden suites are the alternative for lots without laneway access. The City now offers free pre-approved "Made in Toronto" plans that comply with the Ontario Building Code, saving thousands in custom architectural fees and speeding permits. Development charges can be deferred interest-free for 20 years. Strict soft landscaping minimums apply — 60% of the area between the main house and suite on lots 6 m wide or less, and 85% on wider lots. Fire access must provide a clear path within 45 m of a public street via the laneway or 90 m through the side yard.

While we specialize in second-floor additions, we also design and build ground-level rear additions, side additions, and laneway or garden suites. Whether you need to expand your main floor living space, add a family room, or build an income-generating secondary suite, we handle design, permits, and construction as a single integrated team.

These additions typically provide strong returns: an immediate property value increase of roughly 80–90% of construction cost, rental income potential of $2,500–$3,500 per month for premium units, and increased buyer appeal — properties with suites often sell 20–25% faster. In neighbourhoods like Forest Hill and Rosedale, high-quality suites that match the main residence deliver the highest returns.

For homeowners in Toronto's established neighbourhoods, adding on is often the more strategic choice. You avoid land transfer taxes and real estate commissions while building equity in a location you already love. An addition lets you create a space tailored exactly to your family's needs without the stress of a move. On average, you can expect an immediate return of 70–85% of your investment in increased property value.
