Summary: A Manhattan polyomino, is a finite union of integer rectangles put on a same line. We give a simple characterization of Manhattan polyominoes which can be tiled by rectangles ${1 \times p, q, \times 1}$ and consequently a linear time (with short encoding) algorithm to decide if a Manhattan polyomino is tilable by ${1 \times p, q, \times 1}$.
