Two unit bldg does not have a back door

[Wave Taylor]

I looked at a 2-unit bldg. in a not so great neighborhood. The lower unit  looks like the bedroom was an  addition and the building for does not have a backdoor. Should this be a concern, as far as being able to rent, especially for Section 8 purposes? Has anyone ever run into a situation like this?

Make sure that the property is Legally known to the city an 2 units property. 

If its not a Duplex you may have cod violation issues....
