Landlord Tenant rental dispute

Asked in Hoboken, NJ - almost 2 years

My landlord refused to make repairs so I contacted the management office & owner to discuss the situation, but I was dismissed. I informed the management company that I would not pay any rent increases until the repairs were made. My landlord accepted my rental payments that did not include the 3% annual increases. It took years, but the state eventually forced the landlord to repair the leaks. I then started to pay rent increases after the repairs were made. Now my landlord is subjecting me to 3 rent increases in 1 year which amounts to over $400. I cannot locate a copy of my lease, but my rent was supposed to increase 3% per year (rent stabilized). The landlord refuses to give me a copy of the lease.Can I file a case against my landlord re: the rent increases or do I have to pay?
