An AG pool is not considered a permanent structure/pool, so that might make a difference.
Since you've spoken with the inspector, ask him what he wants to see. If you can put the heater and electrical next to the house.
Directions we originally followed showed equipment next to the pool had to be 4 ft away to avoid climbing hazard for kids trying to get in the pool.
We moved our equipment 20 ft away from the pool to hide it and the pipes are buried.
