Manitoba publishes municipal-planning guidance for secondary suites, including basement, garden and coach-house forms. The local zoning bylaw decides whether and how those forms are enabled.
Manitoba secondary-suite planning guidance ↗What the Brandon source actually tells you
The Brandon link is topic-specific, so it is the strongest local starting point for this page rather than a generic city homepage. The verified local material specifically points toward zoning.
For Brandon, the current source summary is therefore most useful for checking zoning. Do not substitute a neighbouring municipality’s numeric rule for anything the local source leaves open.
