When crews arrived, they found heavy smoke coming from the apartment.
They say the fire started on the second floor and spread to the attic of a unit next to it.
Crews say this was a wind-driven fire and this is what caused it to spread.
They were able to stop it with an aggressive fire attack. It took an hour to get the flames under control.
Four units were damaged; two were damaged from the fire and the others were damaged due to smoke and water damage.
Crews are still watching it for flare ups since it is still windy in the area.
