ooooow... your in trouble! I got one of the infamous HOA LETTERS, when my wire tomato cage was 6in above the fence. Your backyard looks like mine in Tucson, till I moved further out in the boonies. Also got one for a new backporch light I installed ..(no direct lighting outside)..
This post is partly tounge in cheek, but also because I hate HOA's.
Beautiful job! Hope it flys.
