There are things I'm not sure I understand here.

The example you show is a shopping mall, with the address tagged on
the building as a set of housenumbers (as you say, 97, 99, 101...)

But  then you say all the stores share the same housenumber.

I'm not sure I understand that, so maybe you an clarify it for me.

Are you saying that all the stores are 97, 99, 101, 103, etc. or that
one store, say the Garde bakery, is at 99, and the Schäfer's Backshop
(you people sure do love your bakeries!) is at 103?

If the stores have a housenumber- and you know that housenumber,
include it in the store.

If they're shared amongst all the stores equally, ie they all have 97,
99, 101, etc. then I'd tag the building.

Very useful to have an example...

If each shop had one housenumber, then I'd remove it from the building
as I added it onto the shop.

It's okay if both objects have the address tag, because both are correct.

The building I live in is mixed use. Some of the building contains
retail shops, and then there's a large apartment complex (which is
where I live).

I've tagged the shops with the same addr:housenumber as the apartment
complex, because that's the truth.

Google is confused about this and thinks I live in a store, but
Nominatim simply asks if I mean the apartment complex, or the

[1] I'm anthropomorphizing a bit here. What really happens is that
Google returns a single value for the address, while Nomatim returns
multiple values.
