That doesn't seem like a useful security question at all. Anyone can trivially find out the answer via online maps, and meanwhile the actual person who lived at that location might not necessarily know the answer themselves without looking it up. At most, if you use it as a trick question ("Hah, caught you, the person you wanted to authenticate as never lived on RandomName St!"), you get one bit of information, which you could get much more straightforwardly by asking "Have you ever lived on RandomName St?".


Street names are quite common though, knowing the street name is unlikely to give you enough information to answer the question. The real person however, would know the location of the street and be able to use this to look up the right answer if they didn't already know.
