Under NYC rent laws, a landlord generally must provide adequate notice before refusing to renew a lease typically 30 to 90 days, depending on how long you’ve lived in the unit. However, if the non-renewal stems from discrimination, retaliation, or attempts to force you out without proper legal grounds, you may have a case. Document everything: emails, texts, maintenance requests, or anything that may show your landlord's intent. Consult an experienced tenant attorney who can evaluate your situation and help you respond with a legal defense or court filing if necessary.
