Pool Requirements

All outdoor pools, spas and hot tubs with water over 24" deep, must be protected with a barrier as outlined below:

Height

  • 48" minimum above grade measured from the outside face of the barrier.

Openings

  • 2" maximum between grade and bottom of barrier
  • 4" maximum between top of above-ground pool wall and bottom of barrier when barrier is attached to top of pool wall.
  • All other openings shall not allow the passage of a 4" diameter sphere.

Climability

  • Solid barriers (stone walls, etc.) must have no protrusions or indentations.
  • Horizontal members less than 45" apart must be located on the inside face of the barrier. In such cases, the space between corresponding vertical members must be 1.75" or less.
  • Maximum mesh size for chain link fences shall be a 2.25-inch square unless the fence is provided with slats fastened at the top or the bottom which reduce the openings to not more than 1.75".
  • Decorative cut-outs within a vertical member must not have openings greater than 1.75".

Access Gates

  • Must meet height, opening and climb ability requirements for barriers.
  • Must be self-closing and self-latching, and must open outward away from pool.
  • Latches less than 54" from the bottom of the gate must be located on pool side at least 3" from top of the gate. There shall be no openings 1/2" or greater within 18" of the latch.
  • Latches located greater than 54" from the bottom of the gate may be located on both sides.

  • Dual Drain Separation:
    • Minimum of two suction outlets of the approved type.
    • Minimum distance of three feet horizontal or vertical separation between suction outlets.
    • They shall be piped so that water is drawn through them simultaneously through a vacuum relief-protected line to the pump or pumps.
