Founded in 1981, the Tenderloin Neighborhood Development Corporation's (TNDC) mission is to provide safe, affordable housing with supportive services for low-income people in the Tenderloin community and be a leader in making the neighborhood a better place to live. TNDC owns and operates 45 buildings and houses over 6,300 residents providing 4,293 homes in 7 San Francisco neighborhoods. Most of our tenants earn less than $20,000 a year and are considered by the U.S. Dept. of Housing and Urban Development as being extremely low-income. In addition, TNDC supportive services (a team of on-site social workers and an after-school center for children and teens) are providing a foundation for building better lives.
