The building is listed on the New South Wales State Heritage Register and the (now defunct) Register of the National Estate, with its interior listed in the City of Sydney Local Environmental Plan. A plaque commemorating the building's history and continuing association with Hong Kong was unveiled on 23 June 2011 by Governor of NSW, Marie Bashir, and Hong Kong Chief Executive, Donald Tsang. In late 2014, during the "Umbrella" protests in Hong Kong, the street-level frontages of Hong Kong House were covered with yellow, pink and blue Post-it notes containing messages of solidarity with the protests.
