Thank you for the links and info, I think these people are within their limits on plants...if I can't reason with my mom to look into it for legalities sake then maybe she will if only to see if there has been damage to the indoor areas.

They have not had a walk thru in 5 years and all she knows is that they put up a huge fence around the field and told her there was nothing to see, "just storage" in the garage and upstairs bedrooms
