Over 1 year ago I took chicken wire and some 1" x 4' sticks and made a big area for my dogs to run. I recently had a pool put in but have only move 1 side of erected chicken wire. I have received a letter in the mail today from my HOA stating that my pool was done and I needed to remove my safety fence immediatly. Well it was never a safetly fence. Since it has existed for over 1 year is there any grandfather law or am I able to leave it and call the area around the chicken wire a garden. My HOA is run by 2 freinds in the neighborhood and don't get along with either one. This is really a way for them to pretend that they run the community. I just want to know if there is anything I can do to keep it there legally. I do plan to put up a wood fence in the very near future, but now its a principle thing. In the letter there was no time frame to remove it just said immediately is that legal or do they need to give a time frame.
Thanks for all or any help anyone can provide.
