Firefighters arrived within minutes and found flames from the two-story residence, which was spreading to the next-door house.

The alarm was upgraded to a Code 4 assignment to bring additional fire crews to the scene.

Firefighters quickly extinguished the fire outside that was spreading next door, while fire crews began an interior attack on the fire at the first home and searched for occupants.
