One challenge in creating affordable housing is finding land that can legally accommodate the type and scale of housing needed. Cambridge's new Zoning By-law removes many of these barriers by allowing a much wider range of housing forms across the city.
By allowing single detached homes, semi-detached homes, townhouses, stacked townhouses, triplexes, multiple dwellings, and apartment buildings to be permitted in more residential areas, there are significantly more sites that could be considered for affordable housing development.
The expanded permissions for Additional Residential Units (ARUs) are particularly important for affordability. Allowing additional units on a residential lot creates new rental opportunities without requiring large-scale redevelopment. These smaller rental units are often more affordable than newly built apartments and can increase rental supply throughout the city, support seniors aging in place, enable multi-generational living arrangements and provide homeowners with rental income that helps offset housing costs.
The zoning framework creates a housing range. Residential 1 and 2 zones support low and medium-density housing, enable infill development and neighbourhood intensification and create opportunities for townhouses, triplexes, and other "missing middle" housing. Residental 3 zones allow higher-density development, including buildings up to 15 storeys along major roads. It also supports larger affordable housing projects near transit, services, and employment areas and makes more efficient use of urban land and infrastructure.
