Madison FAQ
Does my above-ground pool need a fence?
If the pool walls are at least 48 inches tall and the ladder is lockable or removable, the pool walls can serve as the barrier.
Is a pool cover enough?
Not for pools. Only hot tubs and spas with a rigid, locking ASTM-compliant cover can substitute for a fence.
Middleton FAQ
Does my existing 42-inch privacy fence meet Madison's pool barrier rule?
No. SPS 390 and the ISPSC require 48 inches minimum. You would need to add 6 inches (often via trellis or lattice extension) or replace the section facing the pool. Madison inspectors will not pass the final pool inspection without it.
Do I need a barrier for an inflatable kiddie pool?
Not if water depth is 24 inches or less. Pools deeper than 24 inches (including most inflatable family pools) trigger the full ISPSC barrier requirements under SPS 390.
