The TIAA, like Seagram & Sons, supported landmark status for the building. In early 1988, just over thirty years after the Seagram Building had been completed, the TIAA filed documentation with the LPC requesting that the Seagram Building's exterior, lobby, and plaza be considered for landmark status. The Four Seasons' operators separately also endorsed landmark designation for their restaurant's interior in the Seagram Building. On October 3, 1989, the Seagram Building's exterior was designated as a landmark, while the lobby and Four Seasons Restaurant were both designated as interior landmarks. The Four Seasons was only the second restaurant interior in the city to be designated a landmark, after Gage and Tollner in Brooklyn. While the TIAA had no issue with the exterior and lobby landmark designations, it sued the LPC in 1990 to get the designation for the Four Seasons removed, on the basis the restaurant was personal property. The designation was held up by the state's Court of Appeals in 1993. The Brasserie, not covered in any of the landmark designations, was renovated in 1999 after being damaged by a fire in 1995.
