time time live: 30 days (to find shelter AND move, or be on the streets with everything you worked for seized)
if you don't leave: police arrest you for trespassing, judge puts you in jail. you are then maybe cut off from all welfare because you have a "conviction" in your past
reason: any reason landlord has
problem: if rent is very high or there are no vacancies you are in ALLOT of trouble, quite possibly dead, if you receive an eviction notice
if your landlord descriminated or cheats: you may not be able to fight it - the Court fees of usa's "free courts" are SO EXPENSIVE that if eviction doesn't kill you the Court fees of the landlord CERTAINLY WILL KILL YOU, with both debt and lack of housing. noting - all local shelters are usually full - often occupied by people who don't even qualify - friends of democrats and etc.
