That is not a sun room, it is a screened pool enclosure and the pool rules take precedence over 210.52. It will also show up differently on the tax appraiser plot plan.
I would expect the receptacle serving the rear of the house to be outside the enclosure somewhere. That block wall is not really a "sea wall" it is just a retaining wall to hold the box of dirt the house sits on. You notice the hose bib is in it.
This must be an old pool. I doubt you could build that today and you certainly would need to relocate the door handle on the cage door. (53" min height).
The door has to open "out"
I would also want to know if the windows are tempered glass and are the frames bonded. Is the cage bonded?
Where is the 36" of clear walkway behind the pool?
The strange thing is the screen cage seems fairly new, based on the cable anchor and the size of the roof members.
It is possible it was inspected by a structural inspector who doesn't understand pool rules (or unpermitted).
Pool finals are usually done by the electrical inspector, strange as that seems.
