Hello, I was looking to maybe purchase a multi unit home in New Jersey. It appears to be a legal two family home. Both units only have one means of egress; except the 1st floor you I suppose you could get out through the basement. The second floor only has one doorway with steps that lead up to the apartment. That is the only means of egress in the apartment and there are no fire escapes, balconies or steps of any sort. In the event of a fire blocking the one doorway me or a potential tenant would be at the mercy of jumping out a window. Is this legal? The home is old and appears to have been built in 1890 (I am unsure if it was always a 2 family or was converted; still waiting on bldg files from town hall). I'm told that the lack of second egress and fire escape might be legal because of when it was built. If that is accurate, is there anything that would trigger a required update? Thanks.
