Recent Operating History

In 1986, Kennedy Supplee Associates LP (KSA) signed a 55-year lease with the National Park Service, restored the building, and operated it as the Kennedy Supplee Mansion Restaurant. Following the 1987 renovation by KSA, the restaurant operated with approximately 1,100 square feet of dining space located on the first and approximately 2,200 square feet of dining and bar space on the second floor. The third floor was largely given over to HVAC equipment, but it also contained an office and liquor cage. Sections of the basement were used for cold storage and dry storage. See foor plans below. The company entered Chapter 11 bankruptcy in 2005. The mansion has been vacant since 2006.
