If the condo committee has the authority under the documents creating the condominium and subject to which your friend purchased the condo (e.g. any deeds or master deed) to ban renters, then they can do this. If your friend does not remove you as renter in that case, she could be fined or the condo could try to take other legal action against her. Since you are on an oral (also often called a verbal--though oral is the better term) lease, you are a month to month tenant and your friend can give you notice terminating your tenancy--there is simply no such thing as a five-year oral or verbal lease (to have a five-year lease, it would have had to have been in writing). Therefore, you can be required to leave.
