I own my mobile home I recieved a notice (all neighbors did) that we MUST take our skirting off and check to see if any pipes are leaking if they are its a 75 dollar fine and you have 48 hrs to fix is this legal? (in nebraska) also the land is (and water) containmented and there are holes everywhere in the yards notice said we must get the dirt to fill in I only own my mobile and pay lot rent thank you
