Start typing an address in Toronto. Select from the suggestions to look up zoning information from the City of Toronto's Zoning By-law 569-2013.
Understanding Toronto Zoning
Most Toronto properties are governed by Zoning By-law 569-2013, a citywide by-law that harmonized the former municipal zoning regulations following Toronto's 1998 amalgamation. Your zone designation determines what can be built on your property: building types, heights, lot coverage, setbacks, and more.
Reading your zoning results
The lookup above queries the City of Toronto's official geospatial service and returns five pieces of information that shape what you can build. Tap a row to read more:
What you can typically build by zone
Under the 2023 Multiplex Amendment (Official Plan Amendment 649, adopted May 10, 2023), duplexes, triplexes, and fourplexes are permitted as-of-right in all residential zones (R, RD, RT, RS, and RM) citywide. This was the most significant residential zoning change in decades, eliminating the requirement for minor variances or rezoning to add units on most residential lots.
Specific building forms still depend on lot dimensions, height limits, main-wall height rules, building length limits, and any property-specific exceptions shown in the lookup above. The summary card at the top of your results lists typical projects suited to your zone.
When to request a Preliminary Zoning Review
For any project beyond a straightforward interior renovation, a Preliminary Zoning Review from Toronto Building is strongly recommended before investing in architectural plans or retaining a builder. As of March 1, 2022, the City offers three programs:
- Zoning Applicable Law Certificate (ZAP) — a comprehensive review of zoning and applicable law. Enables a complete application for a building permit.
- Zoning Certificate Review — detailed zoning compliance review. Fee is 25% of the future building permit fee and is credited back when the permit is issued.
- Zoning Use Review — confirms whether a proposed use is permitted, without requiring plans.
Full application details and forms are on the City's Apply for a Zoning Review page. For a visual check of surrounding properties and overlays, the Zoning By-law Interactive Map is the authoritative source.
