Three adults required housing assistance from the American Red Cross Sunday after fire ripped through the Niagara Falls home they were living in at 1967 Falls St.

Niagara Falls firefighters responded to a call at 1:22 a.m. Sunday for the two-and-a-half-story home that sustained $15,000 in damage - $10,000 to the home and $5,000 to its contents, fire officials said.

The cause of the blaze, which began in a second floor stairwell, is under investigation. No injuries were reported.

The Red Cross was notified to help and a building inspector had been dispatched to the home. Fire officials identified the home’s owner as George Sawyer, though he was not one of the three living there when the fire broke out. Fire officials brought the fire under control within an hour.

Falls firefighters also are investigating the cause of an early-morning fire at a vacant home at 1150-and-a-half Whitney Ave.

The 2:50 a.m. fire started on the second floor and caused $5,000 damage, firefighters said. The home is owned by the City of Niagara Falls. No injuries were reported.
