The State of Illinois purchased Hotel Florence and the Administration and Factory Complex in 1991 and incorporated it into a state historic site through the Illinois Historic Preservation Agency. However, a 1998 arson destroyed much of the latter building before it could open to visitors. It is now in the process of reconstruction. President Barack Obama designated Pullman as a National Monument, thus a component of the NPS, on February 19, 2015. It became the first unit of the NPS in Chicago. In 2015, the National Parks Conservation Association and the Chicago Chapter of the American Institute of Architects published a report on development for the park.
