Riverbay Corporation is a not-for-profit housing corporation that manages Co-op City, the largest cooperative housing development in the world, located in the Bronx, New York. Established in 1965, Riverbay oversees a massive residential complex spanning 320 acres, consisting of 35 high-rise buildings and seven townhouse clusters, housing approximately 45,000 residents. The corporation is responsible for managing all aspects of Co-op City’s operations, including maintenance, security, utilities, and community services. Riverbay employs over 1,000 staff members and manages an annual operating budget exceeding $200 million. The development includes various amenities such as shopping centers, educational facilities, houses of worship, and recreational spaces. As a Mitchell-Lama development, Riverbay Corporation operates under New York State’s supervision to provide affordable housing to middle-income families. The organization maintains a cooperative ownership structure where residents purchase shares in the corporation rather than owning their apartments outright. Riverbay’s board of directors is elected by the shareholders and works in conjunction with professional management to oversee the community’s operations. The corporation has played a significant role in maintaining one of New York City’s largest and most stable middle-class communities, while facing challenges such as aging infrastructure maintenance and energy efficiency improvements.
