The mayor holds office at Iba Municipal Hall.

Like all local government heads in the Philippines, the mayor is elected via popular vote, and may not be elected for a fourth consecutive term (although the former mayor may return to office after an interval of one term).

In case of death, resignation or incapacity, the vice mayor becomes the mayor.
