Missing Middle Housing

Missing middle housing refers to multi-family housing options – as opposed to single, detached houses – that can increase density in single-family neighborhoods while providing affordable rental and purchase options. These housing options can include rowhomes, multiplexes, laneway houses, duplexes, triplexes, fourplexes, and cottage clusters, as well as accessory dwelling units (ADUs), backyard cottages and mother-in-law suites. Exclusionary single-family zoning often makes such forms of mixed-income home types illegal to add, retrofit or build.
