-1, if there is no gap in reality, no shouldn't map one.

-1. You can do this to be faster in the beginning, but it is less
acurate, looses information, and get's less practical when you come to
the point that you add additional information to some of the
buildings.

They should share boundaries. I personally tend to draw separate
polygons (boundary ways overlapping) but there is also other mappers
that promote shared ways (requires MP-Relation, why I think this gets
stuff more complicated in simple situations (2 common nodes)).
