Usually this would be mapped as a node (point) for the shop, set inside
the perimeter of the building. The node gets tagged with all the
information specific for the shop (name, phone, opening_hours, etc.) The
building area gets tagged with all of the physical attributes of the
building (height, building style, sometimes the building has its own
name that it keeps regardless of what shop is occupying the ground
floor.) The address tags would also generally go on the building itself
-- unless the building has multiple addresses.
We definitely don't want two buildings at the same location to indicate
the two different uses of a single building. It is possible to draw an
area for the bottom floor shop instead of a node -- just tag the area as
a shop, not as a building. And add the level=0 tag, as you mentioned.
(And it probably wouldn't be the *entire* bottom floor of course; you'd
want to leave room for the stairs for instance.)
The general rule is *not* to map any specifics of private areas of
buildings -- the apartments on the upper floors, for instance. You can
use the building:units= tag to indicate the number of apartments, and
addr:flats= tag to list the apartment numbers, but that's generally as
far as we go.
