[header] How to sublet an apartment in new york city [title] Ensure your lease or condo agreement allows it. [step] Some renters or condo associations will not allow subletting so be sure to research this before initiating the process. Some will allow it but only with notification, sometimes with a period of notice like 30 days in advance of move-in. 
Some will charge additional fees or have their own process for approving subletters. Read your lease, condo agreement, or directly ask your renter/condo association.
