The provisions of this chapter shall <br />control the design of barriers for residential swimming pools, <br />spas and hot tubs. These design controls are intended to provide <br />protection against potential drownings and near-drownings by <br />restricting access to swimming pools, spas and hot tubs. <br /> <br />AG105.2 Outdoor swimming pool. An outdoor swimming <br />pool, including an in-ground, aboveground or on-ground pool, <br />hot tub or spa shall be provided with a barrier which shall com- <br />ply with the following: <br /> 1. The top of the barrier shall be at least 48 inches (1219 mm) <br /> above grade measured on the side of the barrier which <br /> faces away from the swimming pool. The maximum verti- <br /> cal clearance between grade and the bottom of the barrier <br /> shall be 2 inches (51 mm) measured on the side of the bar- <br /> der which faces away from the swimming pool. Where <br /> the top of the pool structure is above grade, such as an <br /> aboveground pool, the barrier may be at ground level, <br /> such as the pool structure, or mounted on top of the pool <br /> structure. Where the barrier is mounted on top of the pool <br /> structure, the maximum vertical clearance between the <br /> top of the pool structure and the bottom of the barrier shall <br /> be 4 inches (102 mm). <br /> 2.

Spacing between vertical members shall not ex- <br /> ceed 1.75 inches (44 mm) in width. Where there are deco- <br /> rative cutouts within vertical members, spacing within the <br /> cutouts shall not exceed 1.75 inches (44 mm) in width. <br /> 5.
