Rent and Utilities: Rent Increase in New Jersey 16.67%

My question involves landlord-tenant law in the State of: New Jersey I live on 2nd floor, 2 family private home where landlord does not reside in Hudson County, 07029 zip, NJ.My current rent is 1200/mo. I just received a rent increase to $1400/mo. I pay my rent usually before date due and have never been late. No problem with landlord whatsoever. This is an increase of 16.67%. Is this legal? I live in Harrison, NJ.

Thanks in advance for your help!
