Cannon Renewal Project Updates

Below is the latest information on current work underway to renew the Cannon House Office Building during the Cannon Renewal Project.

Cannon Building Roof

A protective covering has been erected over the existing roof to help mitigate noise disturbances and provide a watertight seal during the rebuilding of the fifth floor. The west wing's entire fifth floor – including the walls and roof – has been dismantled. Crews are in the process of rebuilding the fifth floor.


Phase 1

Location: West wing
Dates: January 2017-November 2018

The entire west side of the building, from the basement to the fifth floor, is closed. Work includes demolishing and rebuilding the fifth floor, conserving the exterior stonework and rehabilitating the individual office suites.

Cannon Building Basement Rotunda Enclosed Walkway

An enclosed walkway is now located in the Cannon Building basement rotunda. The walkway allows the Cannon Renewal Project to perform construction work in the basement rotunda while also maintaining underground access to the U.S. Capitol and other House office buildings.

Access from the Cannon Building to the U.S. Capitol (Cannon Tunnel) and Longworth Building will be available at all times. There will be lines for staff-led tours to the U.S. Capitol and for staff and official business visitors. The enclosed walkway will remain in place for the duration of Phase 1, scheduled for completion in November 2018.
