Understanding Additional Residential Units in Barrie: What Homebuyers and Investors Need to Know
As Barrie’s real estate market evolves, more homebuyers and investors are exploring ways to maximise property potential. The City of Barrie recently amended its zoning by-law to allow up to four dwelling units on residentially zoned properties. This move aligns with the City’s Official Plan, which promotes gentle intensification and more affordable housing options while preserving neighbourhood character.
What Are Additional Residential Units?
An additional residential unit (ARU) is a self-contained space with its own kitchen and bathroom. Property owners can create these units within the main house or in a separate accessory building on the same lot.
Examples of permitted ARUs include:
-
Basement apartments
-
Apartments over garages
-
Additions to existing homes
-
Backyard suites or tiny homes
-
Laneway or coach houses
-
Granny flats or garden suites
These units serve as low-impact housing options and provide added value for homeowners and real estate investors alike.
How Do They Work?
Thanks to the 2024 zoning amendment, homeowners can now add up to four dwelling units on a residentially zoned lot. You can add units to existing homes or incorporate them into new builds—as long as they meet the required zoning and safety standards.
For investors, this opens the door to generating passive income or increasing a property’s long-term value. For multi-generational households, ARUs can offer flexibility and privacy within a shared property.
What Are the Requirements?
To ensure quality and safety, the City of Barrie enforces several requirements:
-
Zoning Design Standards: ARUs must comply with local zoning guidelines, which define placement, size, and lot coverage.
-
Ontario Building Code: All ARUs must meet structural and safety standards.
-
Registration: Owners must register additional residential units with the City. Registration ensures the unit is legal and safe, and confirms compliance with the zoning by-law and health regulations.
This step protects property owners and tenants alike and ensures the City’s housing inventory remains accountable.
Why Does This Matter?
For buyers, purchasing a property with ARU potential could mean future rental income or flexible living space. For real estate investors, it creates an opportunity to build wealth through smart intensification strategies that align with Barrie’s housing goals.
As demand for affordable housing continues to rise, properties that already include—or can legally support—additional residential units will stand out in the market.
