TL;DR: my management company is not taking care of smoking, squatters, and trash. I don't have the money for a legal battle. What are some good options to research?

Good morning,

Let me start with a picture I took with my phone this morning from my stairwell: https://ibb.co/zmMBySv. (a picture of a make-shift shelter a neighbor built in my stairwell)

In my building, neighbors constantly use the stairs to smoke (weed and cigs), talk loudly on the phone, and let their friends come into the building and join them at times. The apartment has a door that goes from the stairwell directly to the kitchen/common area, so the smoke and loud noises often come in when we eat or hang out and watch TV.

In the picture, you see a shelter of a person I recognize (I know him by the cloth) who has a sad story of some sort and he got kicked out of the apartment below us for not being able to pay rent. He doesn't speak a word of English, and he chain smokes. I've seen him live on the street at the corner too. One time I went there to take out the trash (we have to place trash outside at the stairwell because there's no trash room or a schute; the super takes care of trash) and there was human feces blocking the door from closing; I think it was him as well, since he has nowhere to go.

The lease obviously says no smoking in the staircase and there are signs everywhere, not that anyone gives a shit (or apparently they do, har har) management is helpless and the super, who I'm on good terms with, told me something along the lines of "what do you want me to do, call the cops? They'll be gone by the time the cops show" - and I get it. I also don't want to call the police: besides a few assholes in their 20s, most people would apologize and move if I say the smoke bothers me, and the story of the guy below is horrible.

Rather, I feel the management company needs to look into this problem once and for all. This is a rent-stabilized building, and they are doing the minimum possible. I've contacted them throughout the years, but the best that happened is to install signs maybe, which everyone ignores. I'm NOT looking to be some kind of a hero and get the neighbors behind me, matter of fact, I hope to move out of here sooner than later. I've put up with much worse in the past and I can go on living (I have been) with this a bit longer.

Still, I want to know, what are some options that I have? Is there something that would not warrant some legal battle in eyewitness news, or something of the sort? Did anyone here manage to handle a case like this successfully and quietly? This is a big management company, you know the type.
