Learn more about The Cannon House Office Building’s renewal and their commitment to preserving our nation’s history.



The Cannon House Office Building, the oldest Congressional office building outside of the Capitol Building, was in need of a complete renewal. The Cannon 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. The 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.

The renewal process is scheduled to take approximately 10 years, with two-years phase aligned to fall between Congressional move cycles. Construction work occurs around the clock, with activities ongoing throughout the day and night.

When completed at the end of 2024, the Cannon Renewal project will provide an effective workplace for the next century to serve the needs of the U.S. House of Representatives and support Congressional operations. The Cannon Renewal is an example of the AOC’s commitment to preserving our nation’s history one project at a time for future generations to appreciate and enjoy.
