San Diego Fire-Rescue battled a fire inside a two-story building in Mission Hills.
Firefighters arrived to smoke and flames inside the large home on Alameda Drive around 11:00 p.m. Thursday.
One man was transported to a nearby hospital with what officials described as minor injuries.
A neighbor, who only wants to go by the name Alex, was in his jacuzzi tub when he says he heard loud bangs coming from outside.
That's when he grabbed a towel and worked to get the man out as fast as possible.
"Because there was some big bangs and there was some oxygen bottles inside the house so that's what I was scared about," Alex told NBC 7.
Officials said there were no oxygen bottles involved in the fire.
