Rebuilding Together New York City is the leading national volunteer organization that, in partnership with the community, rehabilitates the houses of low-income homeowners, particularly people who are physically challenged and elderly, and facilities of nonprofit organizations in need so that they may live in warmth, safety, and independence.

Rebuilding Together New York City takes its cue from the old fashioned idea of "barn raising", with skilled and unskilled volunteers assigned to a particular project. Homeowners and organizations are frequently amazed at the massive amount of work that can be accomplished by caring volunteers in a short period of time!
