To ensure the safety and security of the U.S. Capitol Complex, certain items are prohibited from being brought into the Capitol Buildings and Grounds. While this may be a small inconvenience, planning ahead by leaving these items at home will allow for an expeditious security screening process. Failure to adhere to these established regulations can result in arrest, fine and/or imprisonment, as well as the confiscation and/or destruction of the item. This list is not intended to be all encompassing but to serve as a general guide for what is and is not allowed to be brought into the various buildings on the Capitol Grounds.



The United States Capitol Police thanks you in advance for your attention and adherence to these established regulations in order to maintain the safety of all who visit the U.S. Capitol Complex. We hope you have an enjoyable experience visiting the U.S. Capitol Complex.

Except as otherwise noted, these prohibitions apply to both staff and members of the public. Staff should display and wear their Congressional ID cards during the screening process.
