The NHDS Instant Zoning Report is a free tool for Toronto residential properties. Enter any Toronto address and lot dimensions to instantly retrieve the live zoning designation, including permitted uses, height, lot coverage, setbacks, FSI, and buildable footprint.
The tool interprets the city-wide Zoning By-law 569-2013 across all residential zones — RD, R, RS, RT, and RM — and automatically applies the Major Streets overlay (By-law 1062-2025) where applicable, identifying whether an apartment building of up to 6 storeys is permitted as-of-right.
Fourplex permissions under By-law 474-2023, sixplex eligibility under By-law 654-2025, and garden suite rights under O. Reg. 462/24 are all flagged automatically.
*Not a substitute for a professional zoning review, but a clear and accurate first look at what a site can support.
