Altadena FAQ
What safety features are required for pools in LA County?
A barrier (fence/wall) at least 5 feet high plus at least one additional feature: pool alarm, safety cover (ASTM F1346), isolation fence, or alarmed doors from the house to pool. Anti-entrapment drain covers are also required.
What are anti-entrapment drain covers?
Drain covers compliant with the Virginia Graeme Baker Act that prevent hair, limbs, and body entrapment at pool drains. All pools and spas must have them. Covers must be replaced before their expiration date.
Do I need CPR signs at my pool?
The CA Building Code requires CPR signage and emergency contact information posted in the pool area. This applies to residential and commercial pools. Signs are available from pool supply stores.
Carson FAQ
Do I have to retrofit my old pool to add safety features?
No. HSC § 115922 applies at the time a building permit is issued for new construction or remodeling. Pre-existing pools are not required to retrofit, though doing so is strongly recommended and is often required by home insurance carriers.
Are public or apartment-complex pools covered by the same rules?
No. HSC § 115925 exempts public swimming pools and most apartment/condo complex pools from Article 2.5; those are regulated as public pools under separate California Code of Regulations Title 22 Division 4 Chapter 20 standards enforced by LA County Environmental Health.
Does Carson require alarms on every door if I choose option 4?
Yes. HSC § 115922(a)(4) requires exit alarms on every door and window providing direct access to the pool area, not just one.
