Retaining Wall

I have a large retaining wall which holds up the hillside supporting my home and a neighbor's home. It was built by Toll Brothers circa 2013. I would like to place a swim spa/hot tub near the edge of the wall, but I want to be certain that the load will not cause any structural issues. I really just need to know if the structural integrity of the wall be be compromised in any way by the weight of a swim spa/hot tub. Thank you.
