The Enterprise family of companies was launched in Maryland 30 years ago by Columbia’s founder, James W. Rouse, and his wife, Patty, to combat poverty by streamlining the financing and development of affordable housing. Three decades later, Enterprise has become an agenda-setter for the affordable-housing community in a challenging time. Financing for affordable-housing construction is growing scarcer as federal and municipal budgets are squeezed. Enterprise recently published a report, “Community Development 2020,” that lays out a vision for the way affordable housing should be approached in the coming years. The report details five points Enterprise sees as critical to maintaining a viable affordable-housing system in the United States.
