The New York City 15/15 Supportive Housing Initiative aims to fund and develop 15,000 new units of supportive housing in New York City over the next 15 years. This far reaching and comprehensive initiative targets the most vulnerable homeless New Yorkers in need of supportive housing. Supportive housing combines affordable housing with social services to help special populations, including individuals and families with serious mental illness, substance use disorders, or disabling medical conditions. The City’s 15,000 unit plan is comprised of a projected 7,500 newly-developed congregate (single-site) apartments and a projected 7,500 scattered-site apartments. NYC 15/15 rental subsidy is available to provide project-based rental assistance to eligible households living in units awarded social service funding through the New York City Human Resources Administration’s (HRA) Request for Proposals (RFP) for the Provision of Congregate Supportive Housing.
