The New York City Housing Authority (NYCHA) is the largest public housing authority in North America, providing affordable housing to over 400,000 low- and moderate-income residents across New York City. Established in 1934, NYCHA manages approximately 177,000 apartments in 335 developments throughout the city's five boroughs. The authority generates revenue primarily through federal funding, tenant rent payments, and partnerships with private developers. NYCHA has faced challenges over the years, including infrastructure maintenance and funding shortfalls, but it continues to play a crucial role in addressing the city's affordable housing needs.
