David, I found these in the County code...
From the county code:
http://co.hawaii.hi.us/countycode/County...apters.pdf
in the section: Section 5-1.0.133. Adding chapter 63.
Chapter 63 is added to read as follows:
Chapter 63. PUBLIC SWIMMING POOLS.
is this:
"Section 6309. Fences and Other Protective Devices. Every person in possession of land, either as
owner, lessee, tenant or licensee, upon which is situated a swimming, dipping or wading pool which
contains water 18 inches or more in depth at any point shall erect and maintain thereon a fence, wall or
other enclosure completely surrounding such pool or the property on which the pool is situated, sufficient
to make the pool inaccessible to small children; provided that a dwelling or other building which may
serve as a barrier, may be used as a part of such enclosure. Such fence, wall or other enclosure, including
gates, shall be at least 4-½ feet high (4 feet for residential swimming pools) and with openings that does
not allow passage of a 4 inch diameter sphere.
All gates or doors must be self-closing and equipped with a self-latching device capable of keeping
such gate or door securely closed, with latches placed at least 4 feet above ground or otherwise made
inaccessible from the outside to small children; provided that the door of any dwelling forming any part
of the enclosures hereinabove required need not be so equipped.
EXCEPTION: The provisions of this section shall not apply to any swimming, dipping, or wading
pool on the premises of a hotel as defined in the Zoning Code.*"
Do not know if this applies to residential.... but it reads like it does.... also found:
"Section 25-4-46. Projection of pools.
