Six-plex Multi Residential
Six-plex multi-residential projects offer a compact, efficient form of “missing middle” housing that adds density while remaining compatible with low-rise neighbourhoods. They typically combine multiple self-contained units within a residential-scale building, making them well suited to infill sites, redevelopment of underused lots, or conversion of existing detached properties. Benefits include stronger land efficiency, added rental or resale value, and more attainable housing supply in established communities.
In Toronto, this project type is gaining momentum as the City continues expanding multiplex permissions through its EHON housing program. As of June 2025, City Council adopted permissions for fiveplexes and sixplexes in Toronto and East York District and Ward 23, reflecting a broader market and policy shift toward gentle density, infill redevelopment, and neighbourhood-based housing growth.
