The reasons usually come down to one of four things.

Rental income is the most common: a well-built legal suite in the Halton and Peel market commands steady monthly rent, which can offset the cost of the build over a few years and keep returning after that. Family is the next. An aging parent who wants to stay close with their own space, an adult child who is not ready to buy, or a relative with accessibility needs.

A suite handles that without everyone sharing one kitchen. Then there is value. A legal, permitted unit adds to what your property is worth, while an unpermitted one does the opposite and complicates any future sale.

The fourth reason is the simplest: a basement or garage full of boxes is space you already paid for. Recent provincial changes under Bill 23 opened the door for many residential properties in Burlington, Oakville, and Mississauga to add up to three units without a zoning amendment.



We don't take that as given for your property, though.

Whether it applies to your lot, and which type of unit suits it, comes down to a handful of details we check and verify with the city before you commit to anything. Lot size and configuration. Garden suites need a minimum lot area and room for setbacks, so a narrow or small lot may rule them out.

Existing structures. The state of your basement, garage, or home shapes what makes sense to build. Servicing and parking. The unit needs municipal water and sewer, and each city treats parking requirements a little differently.

The honest answer is that the only way to know for certain is to look at your property, which is exactly what the free feasibility call is for.
