Full Breakdown
City Code section 14-4C-2T3 sets the enclosure standard for private pools, hot tubs, and similar water features. The trigger is a pool with a depth of 18 inches or more where the edge sits less than 4 feet above grade; once that threshold is met, the pool must be completely enclosed by a fence built so a 5-inch diameter sphere cannot pass through any part of it, and the fence must stand at least 4 feet tall. A principal or accessory building can serve as part of the required enclosure instead of a separate fence section.
Every gate and door that opens through the enclosure must have a self-closing and self-latching device that keeps it securely closed at all times when not in use; the only exception is a door on a building that itself forms part of the enclosure, which does not need the self-closing hardware. The building official has discretion to approve an alternative protective device or structure in place of the standard fence, but only if it offers a degree of protection that is not less than an enclosure built to these specifications.
This fencing standard applies on top of, not instead of, the setback conditions in subsection T1 and the lighting condition in subsection T2 that also govern pool placement.
Violations & Fines
Operating a pool 18 inches deep or more without a compliant 4-foot enclosure, leaving a gate without a working self-closing and self-latching device, or using an unapproved substitute barrier violates section 14-4C-2T3 and is enforced as a municipal infraction under section 1-4-2, with civil penalties of $100 for a first offense, $250 for a second offense, and $500 for a third or later offense, each day treated as a separate violation.
