My neighbors upstairs are letting their dogs urinate on their balcony, which urine then drips through the cracks of the plank balcony floor and lands on my balcony. I have reported this time and time again to management and also to corporate when I got no help from the on-site landlord. After each complaint my neighbors retaliate by stomping loudly on the floor for long periods of time and by playing loud music during "quiet hours". I have had to resort to calling the local police on one occasion. What can I do? I have been in this same apartment for 3 years now and have 10 months to go on my present lease.
