Social housing is housing where the land is purchased and construction is paid for with government money, owned by the government, a nonprofit, or a partnership. Units are rented to people of all incomes, with subsidies for lower-income people. The income from high-income residents covers operating costs and new construction. Residents meaningfully participate in all decision-making and governance. Social housing ensures permanent affordability and community stability. Cambridge could initiate social housing projects either through state funding (pending in the Governor’s Bond Bill) or through the establishment of a city revolving loan fund, or both.
