Mountain View FAQ
Do I need a permit for an above-ground pool?
Yes, if it is deeper than 18 inches. Inflatable pools below that depth usually do not require permits.
Can the pool wall replace a fence?
The sidewall can count toward the barrier if it meets the 60-inch rule, but the ladder access must be controlled.
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.
