Carson FAQ
I'm building a new pool in Carson — what fence do I need?
If you choose 'isolation enclosure' as one of your two required safety features, it must be at least 60 inches high (measured from outside grade), have no climbable surface, gaps under 4 inches, less than 2 inches off the ground, and a self-closing self-latching gate that opens AWAY from the pool with the latch at least 60 inches above ground (HSC §115923).
Do I need TWO fences or just one fence plus another feature?
One compliant 60-inch isolation fence counts as ONE feature. You must add a second feature — e.g., an ASTM F1346 safety cover, ASTM F2208 water alarm, exit alarms on doors to the pool area, or a self-closing device on the house door (HSC §115922).
Does the law apply to my existing pool?
SB 442 requirements trigger only when you pull a building permit to build new or remodel. Existing pools without permit activity are not retroactively forced to install new features, but local rules and HOA covenants may still apply.
Are inflatable/portable pools regulated?
HSC §115921 defines 'swimming pool' broadly to include any structure intended for swimming or recreational bathing containing water over 18 inches deep — many portable pools qualify. Carson Building & Safety can clarify case-by-case.

In Lancaster, pool barriers must be at least 48 to 60 inches tall depending on local code. Check your specific requirements.
