Palo Alto FAQ
Is my Intex pool legal without a permit?
Only if it holds less than 18 inches of water; deeper pools require a permit and safety barriers.
Does the pool wall count as the fence?
Not by itself in most cases; state law requires a 60 inch barrier or a compliant combination of features.
San Jose FAQ
Do above-ground pools need a permit in the County?
Yes, when they are deep enough to be regulated as swimming pools they require a County building permit and must meet the five-foot setback in Zoning Ordinance Section 4.20.J, the same as in-ground pools.
Can the pool wall act as the fence?
An above-ground pool's rigid wall can count as part of the required barrier if it is at least 60 inches high under the Pool Safety Act. If the wall is lower or a ladder gives access, you need additional fencing or a securable ladder so the barrier still meets state standards.
