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.
Thursday's fire was the second time in less than 24 hours that firefighters were called to Mount Misery. On Wednesday evening, at about 8:35 p.m., a motorist passing by reported smoke coming from a house on or near Denise Street. The fire department responded, along with the Sag Harbor Volunteer Ambulance Corps, but it turned out to be a false alarm.
