Is it common for SFH tenants to put up above ground pools? They keep popping up this summer! What do you do when it's a good tenant?

Tell them to take it down, it raises your liability, it isn't super common and you don't always catch it but most tenants aren't going to move over that alone.

One did say she's going to move now because I said no pool, and stopped paying rent (protected by Corona).  I know she had an overreaction.  But this has scarred me!

Tell them to remove the pool, too much liability for you and your insurance will not likely cover it unless you tell them and then they will raise your premiums. I don't allow trampolines either, same issue.
