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.

For Steinbach, 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.
