The report gives a brief history of Boston's South End, its housing situation, and the Low Cost Housing Corporation (LCHC), founded in 1965 as a nonprofit organization to provide housing for low income tenants. The rehabilitation process for brickfront row houses is described thoroughly. Details of a training program which utilized volunteers and LCHC construction supervisors to assist trainees in renovating neighborhood buildings for low income tenants are given. Trainees were employed by LCHC or other building rehabilitation or construction firms and received classroom instruction (from LCHC supervisors, five hours per week) and on the job training (from skilled crew members at the construction sites) in plumbing, plastering, painting, woodworking, and electrical work. After varying periods of time in the program, the trainees were employed as follows: 11 as skilled tradesmen, 15 as experienced helpers, and 14 as construction laborers. The report also gives information on tenant relations and community development. Conclusions stress the economic value of the human commitment factor as contributing to the program's success. (NTIS)
