The "One Flag for All Act" seeks to standardize flag displays at federal properties by prohibiting the flying, draping, or other display of any flag other than the flag of the United States . This prohibition applies to the exterior and public-accessible interior areas, such as entryways and hallways, of covered public buildings . These buildings include general federal public buildings, those under the Architect of the Capitol's jurisdiction, military installations, and U.S. embassies and consulates. However, the bill outlines several specific exceptions to this general prohibition. These exceptions permit the display of flags such as the POW/MIA flag , flags representing units of the Armed Forces , and flags of historical significance to the United States. Additionally, flags of visiting diplomats, State flags (for Members of Congress), Indian Tribe flags , and flags representing the local jurisdiction where the building is located are also permitted.
