What the current Burlington suite source says
Burlington’s additional-residential-unit page covers units inside, attached to and detached from the main dwelling. A building permit is required, and the number of additional units that can be considered depends on the property and current zoning.

Ontario: the provincial layer
Ontario’s province-wide additional-unit rules create broad permission on identified residential lands, including three units in a primary house or a two-plus-one main/ancillary configuration. Local setbacks, height and site standards continue to matter.

What kind of unit?
Basement, secondary, garden and laneway units are not interchangeable labels in every municipality. Match the project to the local category.
Is the use allowed?
Before drawing walls, confirm that the property qualifies for the unit type under the current provincial and municipal framework.
Can the building comply?
Do not budget only for finishes. Code work can include exits, alarms, fire separations, mechanical changes and structural alterations.
Can the site serve it?
Site constraints can include parking, sewer and water capacity, electrical service, waste access and setbacks for a detached unit.
The practical Burlington suite sequence
A good sequence is property eligibility, unit type, building design, utilities/trades and inspections. Starting with finishes can hide the expensive constraints.
When a property is marketed with a suite, verify the actual municipal approval file before relying on the rental income in your planning.
