In addition to his political interests, Hart contributed considerable amounts of his time and energy to the housing industry, serving in leadership roles at the local, state and national levels. He was elected president of the Builders Association of Greater Indianapolis in 1966 and president of the Indiana Builders Association in 1969. He received numerous awards from these associations, including “Builder of the Year,” in recognition of his enormous contribution to housing in the Hoosier State. Each year the state association presents the John C. Hart Presidential Award in his honor.
Hart was elected secretary/treasurer of NAHB in 1973 and climbed the leadership ladder to become the association’s president in 1976. That same year, he was inducted into the National Housing Hall of Fame.
Capping a long career in the housing industry and pursuing his keen interest in housing finance, in the early 1980s Hart was appointed chairman of the board and executive director of the Indiana Housing Finance Authority, an agency he was instrumental in creating to help provide mortgages for low- and moderate-income families.
Hart was preceded in death by his wife, Mary Haselmire Hart, and is survived by his brother, William Hart, of Austin, TX, and nine children, 21 grandchildren and 12 great grandchildren.
Memorial services were held on June 10.
