The most important thing is to do document the repair request to your landlord. If you can send an email or certified letter that would be ideal. Secondly, you must read in detail what your current lease states and if you are still unable to decipher the answer reach out to a NJ Real Estate attorney and/or NJ Realtor. Feel free to contact me if you would like for me to look at your lease for you. Best of luck, Joshua Baris RealtorofNJ.
