The Sag Harbor Fire Department responded to a reported oven fire in Mount Misery, just outside the village, on Thursday afternoon.
The occupants of 92 Mount Misery Drive called 911 at 1:54 p.m. Dispatchers told them to evacuate the house.
Fire chiefs arrived within minutes. The fire did not appear to be spreading, as they only asked for a few of the fire trucks to respond.
A chief requested a Southampton Town fire marshal to respond to investigate the cause.
Southampton Town police also were on scene.
