Firefighters made an aggressive interior attack to extinguish the fire while simultaneously searching the home to ensure there were no occupants inside.

Mastandrea said the area does not have fire hydrants and fire tender trucks were called to haul water to the home.

The fire was deemed under control within 20 minutes. There were no residents or firefighters injured.
