The building was constructed in 1963 asFederal Office Building No. 8to house laboratories for theFood and Drug Administration,an agency of the neighboring Health and Human Services, located across the street in theHubert H. Humphrey Building.

Starting in 2008, the office building underwent an extensive, $130 million renovation. The building received new green spaces, heating and air conditioning, electrical systems, more glass and numerous energy- and water-saving features, earning it a "gold" rating under theLeadership in Energy and Environmental Designsystem.

The House of Representatives voted in 2012 to name the building after O'Neill, after a suggestion by thenminority leaderNancy Pelosi.

The O'Neill building opened for occupancy in 2014.

A 2017 law transferred ownership of the building to theArchitect of the Capitol,the agency that owns and maintains congressional buildings. It was then given its current name and opened to public access, like the other House and Senate office buildings.
