Based on data retrieved from the archives of the Taiwanese Governor General's Office during the Japanese period, this paper examines the shaping and the evolution of the ”Building Standards of Official Residences.” During 1901 to 1920,there were sweeping changes in the structures of the local political administrations, which led to changes in the roles of both central government(the Taiwanese Governor General's Office)and the local governments(county, chou)related to governing of local constructions. During the ensuing years following changes of the local political administrations, the ”Building Standard of Ordinary Official Residences” and the ”Building standard of Taiwanese Governor General's Office” have been written and modified. These two documents outlined the basis for the ”Building Standards of Official Residencies.” The ”Building Standard of Official Residence” was abolished after 1945. However, it is still the most important tool to identify and to grade an existing official residence built during the Japanese period.
