I don't know about where you live, but here the city has all sorts of owner, address, structure and parcel shape data on-line for all to see. They likely have more for internal use. The wrong address thing should be a less not more frequent event.
That, however, implies competence and enough 'give-a-d@mn' to get things right in the first place.
I think we are seeing less of that aspect, and that is something all the tools in the world won't offset.
