New Jersey.....rental is a multidwelling; a private house divided into three apartments.
My housemate and I are on the main level. Above his bedroom, is a tenant who plays music excessively loud. I cannot get cooperation from the tenant, the landlord or the police to modify this problem. The landlord has been notified by certified mail of the ongoing nature of this problem and my calls to the police. I have gotten no further cooperation from the landlord.
My housemate may leave. If he does, I may have difficulty rerenting this room because of the problem from upstairs. In addition, the landlord could also refuse my request to replace my current housemate.
What are my rights given the problem of this upstairs noise and possible difficulty in rerenting? What do I do if the landlord refuses me the right to replace my housemate? (I would not be able to afford the rent on my own.)
Thank you.
