The blaze broke out just before 11:30 a.m. at 3736 Southeast 40 highway. 33-year-old Jamie Mechtley was home at the time.
His sister Nicole Cott says he dumped an ash tray in the trash with a hot cigarette in it. He was folding laundry in the bedroom when he smelled smoke and found the kitchen engulfed in flames.
He grabbed his two dogs and got out safely.
Cott says the family had just brought the Christmas Tree in Wednesday night and had hoped to decorate it Thursday.
Damage is estimated at $15,000.
