What Southside United HDFC does

Southside United HDFC, doing business as Los Sures, is a New York State-chartered Housing Development Fund Corporation founded in June 1972 on the South Side of Williamsburg, Brooklyn. It is a community-based non-profit that develops and manages affordable housing for low-income residents, with a stated portfolio serving 5,000+ residents and operating across seven locations. In 1975 it became the first community-based organization in New York City to manage City-owned residential properties, and between 1975 and 1979 it executed a large-scale rehabilitation initiative that established its managed housing portfolio.

The organization's service stack extends well beyond housing. It operates the Southside Senior Center, the Men on the Move senior fitness program, the Southside Childcare program, Casa de la Familia for Latino family support, El Museo de Los Sures community museum, and a food pantry paired with an on-site hydroponic farm serving 1,200+ users monthly and 80–100 seniors daily. It runs the Neighborhood Safety Coalition and Los Sures Lucha, a grassroots tenant organizing coalition, and publishes the Williamsburg Now! neighborhood periodical since 1977. It serves low-income tenants, seniors aged 60+, Latino families, youth, and residents facing displacement in North Brooklyn, with programmatic extension to Queens via a borough director of the Neighborhood Safety Coalition.

The revenue model is a non-profit funding stack: government grants from HPD, NYCHA, NYC DFTA, and federal/state sources; a tiered corporate sponsorship program (Bronze/Silver/Platinum) anchored by Two Trees Management, JP Morgan Chase, Con Edison, Dime Community Bank, Apple, and Mega Contracting; affordable housing development financing; and individual donations collected online via Givebutter. Services are provided free to eligible community members; there is no consumer pricing. Operating headcount is 51–100 employees across the seven locations.
