I've gotten similar calls many times. It seems that they want someone to come over and inspect the whole house as part of a Free Estimate process. It's difficult to know how to handle it sometimes. When something potentially dangerous is found unless you convince them that something will definitely happen it will probably remain as is.
I don't think it would ever be a good idea to tell someone that a violation or a problem is OK. It could come back to haunt you someday.
