In the question Tennessee, a-1 zone - can i rent out on Airbnb? a new tag, a-1,was created. In that question "a-1", was a zoning designation for agricultural land. But in other contexts it might have a quite different meaning. Even where it is a zoning designation, it may not mean the same thing in different municipalities, let alone different states.
I don't think this tag is helpful. Can it be deleted?
