Cannon Renewal Project

The Cannon House Office Building has not received a comprehensive systems upgrade since the 1930s, and many of the building's systems are original – dating back to 1908 or earlier. These systems are past the end of their useful lives and the increasing risk of their failure jeopardizes the building's long-term functionality and safety. Other necessary work includes upgrading infrastructure systems andrepairing the exterior stone façade.

Full project details are at aoc.gov/cannon.
