A tenant keeps complaining about the noise from the tenant upstairs, described as "dragging furniture or something". I spoke to the tenant upstairs and I was assured that they are trying their best as to not cause any disturbance to the tenant underneath their unit. The complaining tenant has called the police on the tenant upstairs, but no findings. What will happen next if the complaining tenant keeps complaining? There is no evidence of the "nuisance" like the complaining tenant calls it. Will the Landlord be fined if the complaining tenant persists in his complaints about the noise and feels that nothing has been done to resolve the issue? How can I handle/solve this situation for the best interest of both parties?
