Shawn, It may depend on what the rental agreement or lease says. If the people congregating in the hallway are there because of your neighbor, he/she may be in violation of something in the rental agreement or lease. There may be a rule as broad as: the tenant agrees to refrain from causing disturbances in the common areas. And if his or her visitors insist on congregating in the building's common areas, his tenancy may well be in jeopardy. On the other hand, if your neighbor really has nothing to do with the presence of those congregating, he needs to make this perfectly clear to the landlord. Your neighbor may be able to get help from Legal Aid for an eviction, if you qualify for their services.
