Heaviest fire appeared to be on the front porch with major extension to the inside of the house and up thru the 2nd floor. Arriving Truck Co #1 had to cut several large tree limbs in front of the house in order to raise their ladder. Fair Lawn Volunteer Ambulance Corps responded to the scene for any injuries and Rehab if needed. Public Service Electric responded to cut power to the fallen lines. Mutual Aid from surrounding communities in Central Bergen Mutual Aid Assn provided assistance at the scene.  There were no injuries at the scene, but the dwelling is uninhabitable.
