Mississauga Garden Suite Regulations

Mississauga permits Additional Residential Units (ARUs) as detached garden suites under Peel Region's official plan and Zoning By-law 0225-2007 (as amended). Garden suites in Mississauga must be between 55 and 100 square metres in size. The City offers pre-approved architectural plans to streamline the permit process, saving homeowners design costs and approval time. Your property must have adequate lot area, meet rear and side yard setback requirements, and provide parking as specified. A building permit is required through the City of Mississauga, and the unit must meet Ontario Building Code standards for a full dwelling — including bedrooms, bathrooms, kitchen, and a separate entrance.

Why Mississauga Homeowners Are Building Garden Suites

Mississauga's housing market makes garden suites an attractive investment. With average home prices among the highest in the GTA outside Toronto, adding a rental unit generates significant income. Neighborhoods like Port Credit and Lorne Park have large lots well-suited for backyard dwellings, while areas like Erin Mills and Meadowvale offer suburban lots that comfortably accommodate garden suites within setback requirements. Mississauga's proximity to Toronto employment centres via the GO Transit network also makes garden suites desirable rental units for commuters.

Rental Income Potential in Mississauga

A one-bedroom garden suite in Mississauga rents for approximately $2,000 to $2,400 per month based on 2025 CMHC and rentals.ca market data for Peel Region. That translates to $24,000-$28,800 in annual gross rental income. Against total construction costs of $250,000-$450,000, a Mississauga garden suite delivers a gross rental yield of roughly 7-8% at midpoint costs — comparable to or better than most GTA real estate investments. Port Credit and Lorne Park units tend toward the higher end of the rent range due to lakefront proximity and GO Transit access to Union Station.
