Enter your address and in 60 seconds you’ll know your zoning designation, maximum building height, what your neighbours have built recently, and which projects you’re eligible for under current Toronto zoning rules — including the 2023 EHON policy that allows multiplexes city-wide.

Frequently Asked Questions
What does this property assessment tool do?
Our free Property Assessment analyzes your Toronto address against the City of Toronto's official zoning data (By-law 569-2013) and tells you what you're eligible to build — garden suite, multiplex, new home, or renovation. It also shows your property's maximum building height and recent building permit activity on your street.
Is this property zoning data accurate?
Yes. We query real-time zoning data directly from the City of Toronto's ArcGIS open data platform, the same source used by city planners. Height restrictions come from the official Zoning Height Overlay (Layer 9). Building permit data comes from Toronto Open Data's active permits dataset, updated daily. Results are labeled "eligible" or "likely eligible" with a recommendation to verify during consultation.
Can I build a garden suite in Toronto?
As of February 2022, garden suites (also called ADUs or laneway suites) are permitted as-of-right on most residential lots in Toronto — no rezoning required. Our assessment checks your specific zoning designation to confirm eligibility. Most detached and semi-detached properties in RD, RS, RT, and RM zones qualify.
What is EHON and how does it affect what I can build?
EHON (Expanding Housing Options in Neighbourhoods) is a City of Toronto policy passed in May 2023 that allows multiplexes — up to 4 residential units — as-of-right in all residential zones. This means you can convert a detached home into a duplex, triplex, or fourplex without a rezoning application. Our assessment factors in EHON when determining your eligibility.
How many storeys can I build on my property?
The maximum building height varies by property. While EHON allows multiplexes up to 3 storeys, your specific lot may have a height overlay that restricts you to 2 storeys. Our assessment pulls the exact height limit for your address from the City's Zoning Height Overlay data — so you get your property's actual limit, not a generic rule.
What building permits have been issued on my street?
Our assessment queries Toronto's active building permits database (updated daily) and counts how many garden suites, multiplexes, new builds, and renovations have been permitted on your street in the last 2 years. This shows you what your neighbours are building and confirms that the projects we recommend are actually happening in your area.
Is this assessment really free?
Yes, completely free with no obligation. You'll receive your results instantly on screen, plus a detailed email summary with links to learn more about each recommended service. A member of our team will follow up within one business day if you'd like to discuss next steps.
What areas of Toronto does this tool cover?
The assessment covers all properties within the City of Toronto municipal boundary — including former municipalities like Scarborough, Etobicoke, North York, East York, and York. Properties under the current By-law 569-2013 get the most detailed analysis. Properties under former municipal bylaws receive a slightly broader assessment with a recommendation to verify specifics during consultation.
