Abstract: A header board bracket for coupling a deck to a structure includes a brace that comprises first, second, third, and fourth plates. The second plate is coupled to and extends perpendicularly between bottoms of the first and third plates. The first plate is dimensionally longer than the third plate. The fourth plate is scalene right triangularly shaped. The fourth plate is coupled to and extends perpendicularly from the first and second plates. The third and fourth plates define a slot. Each of a plurality of holes that is positioned through the first plate is configured to insert a connector to couple the brace to a structure. A plurality of the braces is configured to couple to the structure with the braces horizontally aligned. The slots of the braces are configured to insert a board to retain the board as a deck that comprises the board floats relative to the structure.
