This seems incorrect. If I build a structure on two tax parcels, it can 
exist as a single building. It may not be legal, or may require planning 
tricks that make it two buildings in the eyes of the city, but if I 
survey it and it's one building, I will map it so.

In dense urban areas the edges of buildings can often only be determined 
by surveys, not by imagery, as the imagery only shows the roofs 
generally, and roofs may change appearance within a building or not 
change appearance between two adjacent buildings.
