Can the mayor order the flag to be half-staffed?

Answer: No, the mayor cannot order Flags to be half mast.

Only the president of the United States, or the governor of the state in which the Flag is being flown, can order the Flag to be lowered to half-mast. To fly the Flag at half-staff is a profoundly solemn act. As the American Legion notes, “Those individuals and agencies that usurp authority and display the flag at half-staff on inappropriate occasions are quickly eroding the honor and reverence accorded this solemn act.” That being said, no one below the ranking of governor in each state has the ability to determine the status of the Flag.
