Multiple units with the Lubbock Fire Department responded to the scene of a structure fire at a duplex in South Lubbock Saturday afternoon.

Division Chief Steve Holland tells EverythingLubbock.com the fire was reported at 4315 53rd Street at 2:38 p.m.

Fire units arrived on the scene and found heavy smoke coming from the structure and a fire inside a wall downstairs on the “B” side of the duplex. Crews quickly extinguished the fire in the wall and in the ceiling of that room. A second alarm was called at 2;45 p.m. when it was discovered the fire has spread up a chase to an upstairs room and into the attic.

Both sides of the duplex were undergoing renovations and the structure was unoccupied.

Holland said firefighters had the fire out by 3:20 p.m. A total of 12 apparatus and 41 personnel responded to the fire. There was one minor injury that was treated on scene.

The Fire Marshal’s Office is investigating the cause of the fire.
