Al Smith had a zoo built, and Nelson Rockefeller added the mansion's tennis courts.

In April 2009, Michelle Paige Paterson, wife of Governor David Paterson, announced that as a result of efforts to "green" the operations and maintenance of the building and grounds, the mansion had earned a Leadership in Energy and Environmental Design (LEED) Gold certification from the US Green Building Council.

The mansion is the first governor's residence in the country to earn Gold status using the LEED for Existing Buildings (LEED-EB) rating system.
