Chino FAQ
Does the house wall count as part of the pool barrier?
Only if you use a different SB 442 feature on doors providing direct pool access (exit alarms or self-closing door device with release 54+ inches high). Otherwise the enclosure must fully isolate the pool from the home per HSC §115923.
Is chain-link fence acceptable?
Only if mesh is small enough (commonly 1.75 inches or less) to prevent footholds and pass the no-handhold rule in HSC §115923(d). Standard 2-inch chain link generally fails the climbability test without slats.
Ontario FAQ
Is a standard 6-foot block wall enough for an Ontario pool?
The wall counts as one of the seven features, but the Act requires at least two. A second feature such as a door alarm or pool cover is also required.
Does my existing Ontario pool need to meet the new rules?
Existing pools are generally grandfathered, but remodel permits trigger full compliance with current H&S 115920 barrier and safety feature requirements.
