Antioch FAQ
Do existing pools have to be retrofitted to today's barrier standard?
The Swimming Pool Safety Act applies when a building permit is issued for new construction or a remodel. Existing compliant pools generally do not need to be retrofitted until a permit is pulled for remodeling work that triggers HSC section 115922.
Are hot tubs and spas included in the rules?
Yes. HSC section 115921 expressly defines 'swimming pool' to include hot tubs, spas, portable spas, and nonportable wading pools. Hot tubs or spas with locking ASTM F1346-23 safety covers can satisfy the safety-feature requirement.
Can my house wall be one side of the pool barrier?
Yes, but the doors and windows providing access to the pool must be protected by exit alarms or by a self-closing, self-latching device with a release mechanism placed no lower than 54 inches above the floor (HSC section 115922).
