The history of the EEOB began long before its foundations were laid. The first executive offices were constructed between 1799 and 1820. A series of fires (including those set by the British in 1814) and overcrowded conditions led to the construction of the existing Treasury Building. In 1866, the construction of the North Wing of the Treasury Building necessitated the demolition of the State Department building.

艾森豪威尔行政办公大楼的历史早在其奠基之前很久就开始了。最早的行政办公楼建于1799年至1820年间。一系列火灾（包括1814年英国人纵的火）和过度拥挤的状况促成了现有财政部大楼的建造。1866年，财政部大楼北翼的建设使得国务院大楼不得不被拆除。
