History/Overview

Construction on the Herbert C. Hoover State Office Building began in 1975. At the time, the General Assembly was unable to agree on a name so an essay contest was held among all Iowa public school history classes. The name "Herbert Clark Hoover," in honor of the 31st U.S. president and only Iowan to hold that office, was declared the winner. The original plans for the building called for four floors above ground and two floors below ground. However, when bids were received it developed that there was enough money in the appropriation to add another floor. Today the seven-story Hoover Building houses the largest number of employees on the Capitol Complex.
