The municipal government is divided into three branches: executive, legislative and judiciary. The judicial branch is administered solely by the Supreme Court of the Philippines. The executive branch is composed of the mayor and the barangay captain for the barangays. The legislative branch is composed of the Sangguniang Bayan (town assembly), Sangguniang Barangay (barangay council), and the Sangguniang Kabataan for the youth sector.
St. Anne parish's present church is made of stone and bricks. The heritage building was constructed by Fr. Ferrer in 1853 and completed by Fr. Lucas Gonzalez using adobe stones from Meycauayan City, Bulacan and wood from Betis and Porac, Pampanga. The church is 58 metres (190 ft) long, 14 metres (46 ft) wide and 13 metres (43 ft) high. Parish convent was built in 1866 by Fr. Antonio Redondo. The massive 1857 hexagonal four-storey belltower has blind and open recesses, keeping with the symmetry of the façade. It ends in a balustrade dome topped by a cross.
