The fire broke out around 3:35 p.m. at The Peaks apartment complex located at the intersection of Westerfield Lane and Richmond Lane in Nanuet.
When first responders arrived at the scene, there was a heavy fire that extended from the ground level to the top of the three-story building.
The fire completely gutted eight apartment units -- four on the first floor and found on the second.
Officials say the fire progressed rapidly due to the type of construction.
It took nine fire departments, and about 75 firefighters to get the blaze under control.
No injuries were reported, but one dog was rescued and another is still missing.
Several families have been displaced as a result of the fire.
There's no word yet what caused the fire, and the investigation is ongoing.
