 During the 1990s, Time Hill was occupied by an insurance firm, which subjected the building to an abortive attempt to create a modernistic office complex in the interior; nearly all of the interior was removed and replaced with new styling.After the venture failed, the building was sold at sheriff's sale to Union Institute & University, which already owned the similarly styled Procter and Collier-Beau Brummell Building across the street; a primarily online university, Union was outgrowing its space in the Brummell Building and bought Time Hill with intentions of converting it into the university's headquarters.In 1996, Time Hill was listed on the National Register of Historic Places, qualifying both because of its place in local history and because of its historically significant architecture.
