squalid - dirty
Something ‘squalid’ is filthy and in a bad condition. It is usually in such a state due to neglect or a lack of financial resources as opposed to that being its natural condition. It can also, less commonly, be used to refer to something that is squalid in a more figurative way, particularly with regards to a lack of moral standards.
