Above-ground pool walls themselves can count as part of the enclosure where the wall meets the height standard.

Carson FAQ
Can I use a chain-link fence as my pool barrier in Carson?
Chain-link can comply only if the mesh openings do not exceed the 4-inch sphere test in HSC § 115923. Most standard 2-inch mesh chain-link is compliant for the gap rule, but it can be climbable; many jurisdictions require slats or a smaller mesh to satisfy the climbability standard. Confirm with Carson Building & Safety before installation.
Does my existing house wall count as part of the pool barrier?
Yes — the house wall can serve as one side of the enclosure provided that any doors leading from the house to the pool area are equipped with an SB 442-compliant safety feature, such as an exit alarm (HSC § 115922(a)(4)) or self-closing/self-latching door device with release no lower than 54 inches above the floor (HSC § 115922(a)(5)).
Do hot tubs need the same 60-inch barrier?
Hot tubs and spas at single-family homes are subject to HSC § 115922, but a locking safety cover meeting ASTM F1346 (HSC § 115922(a)(3)) is the most common compliance path for spas in lieu of a full 60-inch enclosure.
