Five questions about your GTA property. We'll match you to the secondary suite types your lot most likely qualifies for — basement, laneway, garden suite, or addition — and the realistic cost range for each.
Note: This is a screening tool based on Toronto's 2025 by-law changes. Final eligibility requires a site visit and zoning verification.
Select the property type. This determines which secondary suites are typically eligible.
Approximate frontage (the side facing the street). You'll find this on your property tax assessment or MPAC.
A laneway is a public lane behind your property — common in older Toronto neighbourhoods like Leslieville, Roncesvalles, the Annex, Riverdale, and Beaches.
Different goals favour different builds. Pick the one that matters most.
Last step. We'll email your eligibility report — no spam, no follow-up calls unless you want one.
Your information is used only to send your report. We never share or sell data.
Based on your answers, here are the secondary suite options most likely available to you, ranked by fit.
This screen is based on by-law averages. The only way to confirm exact eligibility, setbacks, and cost is a free 45-minute site visit. We'll bring a tape measure, walk the lot, and email you a written feasibility report within 5 business days.
Toronto's 2025 by-law changes (847-2025 and 849-2025) made laneway and garden suites as-of-right — no Committee of Adjustment hearings. Provincial setback reductions made roughly 80% of Toronto homes eligible for some kind of suite. But most owners still assume they're not allowed to build. This tool is the fastest way to find out where you actually stand.
