Southampton Town Fire Marshal John Rankin said Tuesday that summonses, including violations for not having working smoke or carbon monoxide detectors, were filed against the owner of the house at 364 North Sea Road and one of the occupants, whose names were not immediately available.
"There were two [smoke detectors] that were there but they were not functional," he said.
Rankin said several other town code violations were issued as part of the appearance tickets.
Southampton Fire Department Second Assistant Chief Chris Brenner said firefighters arrived to find the fire in one locked bedroom after receiving a call of heavy smoke coming out of the house on Monday at 2:52 p.m. At one point, firefighters threw a mattress out the window.
Rankin would not confirm whether the room was locked or if the fire started on the bed. "I can't comment on that right now because it is a very active investigation," he said.
He would not comment on whether the fire was suspicious other than to say the cause has not yet been determined.
Firefighters held the flames to one room on the second floor of the house, extinguishing the fire within 15 minutes of arrival. There was smoke and water damage to the second floor, and water damage to the first floor.
No one was in the house when firefighters arrived and no one was hurt during the course of the fire.
