The building was completed in 1908 and served as a post office and federal building . The federal government sold the building to Weaver Witwer in 1932 after the new federal courthouse was built on First Street . The first floor housed Witwer 's Farm Market and the Me Too Grocery Store and the upper floors housed offices for Witwer 's various operations . The store closed in the mid 1960s and Witwer bequeathed the building to Linn County in 1970 . It was renovated several times between 1972 and 1989 . Before the Cedar River flood in 2008 the building housed several county offices , including Linn County Community Services , Mental Health and Developmental Disability , General Assistance , Protective Payee and State of Iowa juvenile probation offices . It also housed the Witwer Senior Center , which was a non-county organization . The county sold the building to an Iowa City developer in 2010 for $ 570,004
