At least six people have been rushed to the hospital, including 4 adults, a 15-year-old and an infant.
Additional rescue units have been called to the scene in the 400 block of Daly Street.
Laura McColgan lives around the corner when the house came down.
“I was upstairs brushing my teeth. I heard a very loud noise. Not being sure what it was, I came downstairs and went out my back door,” McColgan said. “I went outside and saw everyone running around the corner. I saw the building down, saw the smoke and smelled the horrible smell of gas as well.”
Emergency crews have shut off traffic in the immediate area and have been going door-to-door.
