Contact your local law authority to find out the legal limits on noise for where you live. Often regular living noises are allowed until ten or eleven at night. You may have to have these authorities explain this law to your problem neighbours. Otherwise it certainly constitutes a harassment charge.
My Neighbor Is Constantly Filing False Complaints Against Us For Making Too Much Noise. How Can I Properly File A Harassment Case Against Him Considering. He Has Also Complained About Noises While We Were Not At Home. What Should I Do?
I lived in a condo once and I know the type of neighbour you are talking about. First of all, comply with the bylaws, as you have been. Secondly, get active in your HOA, so that you can make allies. Host a meeting in your place, so all the other owners realize you have a no-shoe rule. Eventually someone will realize that your downstairs neighbour is just a Crabby Patty.
