Rialto FAQ
Does my kid's inflatable pool need a permit in Rialto?
No, if it holds water less than 18 inches deep and is drained when not in use. Larger inflatable pools meeting the 18-inch threshold do need a permit.
Can the pool's metal wall serve as the safety barrier?
Yes, if it's at least 60 inches tall, non-climbable from outside, and ladders/stairs are removable or behind a locking gate.
San Bernardino FAQ
Do I need a permit for an inflatable pool in San Bernardino?
Only if it holds water more than 18 inches deep. Small kiddie pools below that threshold are exempt, but any soft-sided pool that qualifies as a swimming pool under state law needs a building permit and barrier compliance.
Can I use the pool ladder instead of a fence?
Only if the pool wall itself is at least 60 inches tall and the ladder has a locking cover or the steps are behind a self-closing gate with a high latch. Otherwise a separate perimeter barrier is still required.
