One man, Ben Anthony Reyes, suffered a cut in his right foot while trying to save some valuables from his burning house.
At least 1,800 people are now seeking shelter in a covered court, a church, and a compound.
The Sitio Salvacion Day-Care Center, which was put up by Mayor Jaime Fresnedi for poor children, was also burned to the ground.
Fresnedi said he has organized the citys disaster coordinating council together with various departments to provide assistance to the fire victims.
At least 50 sacks of rice and other food items have already been distributed while health officers are keeping watch over the refugees health to prevent disease.
