Where do you live? I'm assuming it is in the US and if that is the case, I do beleive you have solid legal standing. You can't just be kicked out without formal warning and if the landlord neglected to so this, then he/she is liable for your expenses. If you are in the US, see if there is a tenant/landlord number or even visit one of those lawyers that let you talk to them for the first 1/2 hour. Why don't you call up the City and ask directly.
