My question involves landlord-tenant law in the City of New York.
this is another issue involving the case discussed in the "Roommate: can my girlfriend move in if I have a roommate" thread.
I am on a lease with my girlfriend. My girlfriend does not currently live with me. Instead, I live with a roommate, which I have a right to do under NY Real Property Law 235-f. My landlord inquired about who was living with me, and I told her this because I am required to do so within 30 days under that same law. the landlord responded with the claim that I am violating the lease because I am not permitted to sublet without advance authorization from her. She also demanded several forms of ID from my roommate and my roommates permanent address.
Questions:
1. Am I right to think that I am not subletting, given that a subletter is someone who occupies the premises while the tenant is not there, but I am in fact here? So therefore I cannot be in violation of the requirement to request permission before subletting?
2. Am I right to think that I do not have to supply my roommate's identification, but merely inform the landlord of who my roommate is?
3. Lastly, am I right to think that it is not legally possible for a landlord to prohibit you from entertaining any guests at all in your apartment?
Thank you. I will also see a tenant lawyer on Monday and will report back after that, but would certainly apprezziate any of your thoughts.
