Rialto FAQ
Can my house wall count as one side of the pool fence?
Yes, if doors leading to the pool have one of the SB 442 safety features (door alarm, self-closing/self-latching, or power safety cover).
Does a spa with a locking cover need a fence?
An ASTM F1346 listed safety cover can satisfy barrier requirements for a spa under CBC §3109, but a permit and inspection are still required.
San Bernardino FAQ
Can I use my backyard fence as the pool barrier?
Only if the fence meets every requirement of Health and Safety Code 115923, including 60-inch height, no 4-inch openings, proper gate hardware, and restrictions on climbable horizontal members. Most existing residential fences fail at least one criterion.
Is a pool cover by itself enough to satisfy the rules?
An ASTM F1346 compliant safety cover satisfies the second drowning-prevention feature requirement, but you still need the 60-inch perimeter barrier. The cover alone is not a barrier under California law.
