There is continuously people at this apartment outside doing drugs, lighting items on fire in parking lot causing fire department to show up, and other disorderly conduct. Not sure who to report this to but I've had a lady from this building bang on my door (I live in building next door) along with multiple other of my neighbors at 6 in the morning demanding to use my phone and calling me foul names when I said no. They're have been several people in my next door unit who have complained about the behavior.
