Toronto’s Zoning Revolution: Why You Can Now Build Fourplexes (and Beyond)

Toronto’s Zoning Revolution: Why You Can Now Build Fourplexes (and Beyond)

Toronto—and the broader GTA—have recently shifted how we define “home.” What was once strictly single-family housing has transformed into an opportunity for gentle densification, and Hawk PD is keeping a close eye on what it means for custom home projects.

‍

🚧 What's Changed?

On May 10, 2023, Toronto City Council approved Official Plan Amendment 649 along with Zoning By-law 474‑2023, allowing duplexes, triplexes, and fourplexes as-of-right on residential lots across all neighbourhoods.

This is part of the Expanding Housing Options in Neighbourhoods (EHON) initiative, aiming to increase density without compromising the character of low-rise areas.

‍

🧱 What Comes Next?

Since permits rolled out in May 2023, over 200 multiplex permits were issued between May 2023 and July 2024, representing a threefold increase in fourplex builds.

Toronto is now also piloting five- and six-unit houseplexes, currently approved for Scarborough North, with broader city-wide expansion planned by late 2025.

✅ What This Means for Custom Builders and Homeowners

These zoning changes open up new possibilities:
