Hi John - happy new year to all!

Each unit will also have a unique addr:unit too. In theory Nominatim
should pick up the address from the feature enclosing the node (that is,
the building) but in practice it likely won't. It's not wrong to include
addr:housenumber and addr:street for each node, and I wouldn't say that
this was mapping for the renderer at all.

Yes, each with addr:housenumber and possibly addr:unit

Yes, if you have the information separate from the building. There
doesn't seem to be much consensus —
https://wiki.openstreetmap.org/wiki/Addresses#How_to_map_addresses — so
do the easiest thing your conscience can live with.

Yeah; don't do this. We can afford nodes for separate business.

Hey, as a dedicated dweller of duplex land, there are semi-detached
houses everywhere! I've tagged some of them as one building with two
address nodes, as this matches local municipal address point data
practice. [Not that I've imported municipal address data, he adds

“Simple Indoor Tagging”
tagging non_existent_levels=<list>, but I haven't seen that live. You'd
need pretty good internal knowledge to know which were missing. Many
buildings in BC and ON are also missing level 4, 14, etc. Superstition
is a powerful thing ...
