This appears to be an old carriage house (more photos), and the way it's set back from the surrounding houses on an oddly shaped lot (Lot 71) suggests that it predates the other dwellings on the block. Also, if you compare an aerial image from 1924 with one from 2012, you'll see a building of the same dimensions in the same location in 1924, but without all the newer houses around it.
