More Housing Types Coming to Mississauga Neighbourhoods

Official title: Increasing Housing Choices in Neighbourhoods Study

Closed Community Planning Housing & Communities
Mississauga has been changing its zoning rules to allow more housing types in single-family neighbourhoods. The city now permits garden suites, garage conversions, triplexes, and fourplexes on residential lots. A new by-law also makes it easier to build semi-detached homes on smaller lots. These changes aim to create more affordable options for families, young people, and newcomers.

Why This Matters

Looking for a place to live in Mississauga? These changes could mean more rental units in established neighbourhoods. Young adults might find options to stay in the city instead of moving away. Homeowners could add a garden suite for aging parents or rental income. If you live in a single-family neighbourhood, you might see new housing types next door.

Key Issues

  • Should fourplexes be allowed on low-rise residential lots?
  • How can zoning be simplified to allow more semi-detached homes on smaller lots?
  • What rules should apply to additional residential units like garden suites and garage conversions?

How to Participate

  1. Review the City's housing action plan to understand the broader housing strategy.
  2. Learn about the new fourplex zoning rules that have been approved.
  3. Mail your comments to Elizabeth Bang, City Planning Strategies, 7th FL - Planning and Building, City of Mississauga, 300 City Centre Dr, Mississauga, ON L5B 3C1, or email elizabeth.bang@mississauga.ca.

What Happened

The City has completed several phases of this study. New zoning and official plan rules for additional residential units (garden suites, garage conversions, triplexes, laneway suites) have been approved, allowing up to three residential units on one lot. Fourplexes have been approved for low-rise residential lots as-of-right. A by-law to simplify neighbourhood zones is now in force, making it easier to build semi-detached and detached homes on smaller lots. Staff consulted with the public in fall 2024 and brought a recommendation report to Planning and Development Committee on March 3, 2025.
