The Bar Harbor Post Office was entered onto the National Register for Historic Places on May 2, 1986 , and as a federal government commission was affected by two government policies. The first was the omnibus public buildings law in 1902  which was a congressional policy to approve the building, remodeling, purchasing, and budgets of multiple public buildings  through construction standards based on the area’s geography and population . The second was the Tarnsey Act  enacted in 1893 which allowed private contractors and architects to bid on public jobs lobbied as a way to save money and increase the quality of work because under the original process the supervising architect created all designs and oversaw all jobs .
At this time, the Supervising Architect for the Treasury Department’s Bureau of Construction  was James Knox Taylor who served from 1898 to 1912 . During his tenure, federal architecture was influenced by the Chicago World Fair in 1893 and its French “Beaux Arts” designs . Taylor was known for a Greek and Roman style that employed large lobbies and entrances, and although Taylor’s designs tended to circumvent design standardization , the Bar Harbor Post Office’s architecture, as with most government buildings, reflected ideals such as leadership and democracy .
