The Administration Building, Building 1, was formerly used as office space by officers and still showcases restored post office boxes and intricate tin ceiling tiles. Now, the Administration Building offers single room occupancy units. Adjacent areas, including the historic post office, have been renovated into a shared kitchen, dining, community, and living rooms.

Single room occupancy, commonly abbreviated as SRO, is a form of housing consisting of one private bedroom and closet space, with shared amenities available for all to use.
