It took firefighters several hours to bring the fire under control.
Tuesday afternoon, town officials inspected what was left of the building -- the center unit in the complex.
More than a dozen families have been displaced, and two residents were taken away on stretchers. Those are the two in critical condition. Three others were treated for injuries in the fire.
The building has since been condemned, and the Red Cross is helping displaced residents.
