i rented the upmarket aprtment to tenant. over the year in 2024 and 2025, the occupant upstairs has children that run around and stomping affected my tenant. if I were the tenant, I will also want to shift out. so we engage the management office (issue warning letter), security guard and even make police report. the building rules has a regulation no excessive noise after 10pm. but each time the owner upstair will just repeat the same problem.

can I know what else should I do as a owner.
