This lawsuit, filed by Public Advocates, stopped displacement of over 4,000 elderly, low-income persons from San Francisco’s Yerba Buena Redevelopment and spurred creation of 1,000 replacement units. A May 1973 agreement allowed TOOR to develop 400 additional low-income units within the program area. TOOR evolved into Tenants and Owners Development Corporation (TODCO), an organization which persists today and oversees, in the SoMa area of San Francisco, almost “1,000 living units for the elderly, homeless, hotel tenants and people with disabilities.”
