60 days notice: If you have a lease, I would say that the landlord would have to fix the premises for the period. If you are on a month to month, surely the landlord can terminate your tenancy. There may be legal issues which you will have to refer to an attorney. They would include the specific interpretation of the terms of the lease and any municipal laws regarding landlord-tenant relations but, as I remember it, generally, 60 days notice would cover the norm. I believe that in most cases it is a minimum of a full calendar month.
You might find that the health department will evict you, if they have a concern. If you have a lease, you might have an action against the landlord but it probably would not be worth fighting, as long as your security deposit was returned.
