📏 Fence Height & Coverage

Fence is at least 48 inches (4 feet) tall — measured from the ground outside the fence to the top of the barrier. The CPSC minimum; 60 inches is safer.
Four-sided isolation fencing — the fence separates the pool from the house and yard on all four sides. A three-sided fence using the house as the fourth wall is NOT isolation fencing.
No gap larger than 4 inches under the fence — walk the full perimeter and check every low spot. Ground erosion, burrowing animals, and pet digging create new gaps over time.
No climbable objects within 36 inches of the outside of the fence — trash cans, coolers, pool equipment, patio furniture, tree limbs, and planters all become ladders for a determined toddler.
Fence is solid and stable — push firmly on every section. No loose posts, rotting wood, rusted-through metal, or wobbly segments.

Vertical slats are less than 4 inches apart — use a tape measure or a 4-inch ball. If the ball fits through, a small child's torso can follow.
Decorative cutouts are less than 1¾ inches wide — lattice, scroll work, or cut-outs that exceed this give a foothold for climbing.
Chain-link mesh is no larger than 1¾ inches — wider mesh makes an easy ladder. Slat the openings if your mesh is too wide.
Horizontal rails are spaced at least 45 inches apart — closer horizontal rails create a ladder. If yours are close together, the vertical slats between them must be under 1¾ inches.
No gap between fence sections exceeds 4 inches — check every seam, corner, and join where the fence meets the house or another structure.

Self-closing gate closes from any open position — open the gate to 6 inches and release; it must swing fully shut and latch on its own. Repeat from 45°, 90°, and fully open.
Self-latching hardware engages every time — the latch catches automatically when the gate closes. No manual push required.
Latch is at least 54 inches above the ground — or, if lower, located on the pool side with no opening larger than ½ inch within 18 inches of the latch (prevents reach-through).
Gate opens outward, away from the pool — an outward-swinging gate resists a child pushing from inside and closes in the direction of gravity if hinges slip.
Hinges are rust-free and tight — lubricate hinges; tighten loose screws. A sagging gate will not self-close.
No temporary fixes in place — no bungee cords, zip ties, propping rocks, or duct tape substituting for proper hardware. Replace broken parts immediately.
Every gate is locked when the pool is not in use — a padlock, keyed lock, or keypad lock confirms the gate cannot be opened by a child or guest.

Ground under the fence is level — fill washouts, ruts, and animal burrows that create openings under the barrier.
No landscaping acts as a step — retaining walls, raised beds, decorative rocks, and mulch piles next to the fence shorten the effective barrier height.
Tree branches do not overhang the fence — trim any limb that could be used to climb over or fall onto the fence.
Pool equipment is outside the fenced area — pumps, heaters, and chemical storage should not sit adjacent to the fence on the outside, where they become climbing aids.
Door alarms on any house-to-pool doors — if the house wall borders the pool area, every door from the house must have a door alarm (UL 2017 rated) as an additional layer.

Fence posts are plumb and anchored — high winds can shift posts, especially in sandy or wet soil. Push-test every post after heavy weather.
No debris propping the gate open — fallen branches, pool toys, outdoor furniture, or mulch can wedge the gate. Clear the gate swing path.
Gate still self-closes after a storm — wind can bend hinges and move pins. Re-test the self-close and self-latch every time after severe weather.
No new gaps under the fence — heavy rain causes washouts. Walk the perimeter after every major storm looking for new low points.
Re-inspect after any pool maintenance — contractors often prop gates open. Confirm every gate is restored to self-closing, self-latching condition when work is done.

A fence is one layer — not the only layer — four-sided isolation fencing prevents up to 83% of childhood pool drownings (CPSC), but no fence replaces active supervision, swim skills, and rescue readiness.
Fix problems the day you find them — a gate that does not self-close is not a partial fence. It is an open pool. Close the pool to children until the fence is repaired.
Replace, don't patch, failed hardware — latches and closers wear out. Outdoor-rated self-closing hinges and magnetic latches typically last 5–10 years; replace on schedule, not just when broken.
Check local code after any major change — replacing a section, adding a gate, or altering your yard may trigger a permit or code re-inspection. Your municipal code may exceed CPSC minimums.
