you should have distinct osm objects for the building and its occupants. Buildings typically are mapped as ways, get a building=* tag and in case they have a name, add a name-tag.

Offices (or doctors, or any other occupant) on the other hand can be mapped as nodes (inside the building), or overlapping way, or multipolygon relation (e.g. to reuse the building geometry), get their own tags (e.g. office=*, amenity=*, etc.) and will have their own name in their own name tag.

Another common way to map in osm is adding all kinds of tags (for different entities/objects) on the same geometry. I think despite this being very common it is a bad way of mapping, because it becomes unclear (especially to non-intelligent map data consumers) which tags refer to which object (while humans able to understand the language of the name might nonetheless be able to guess right/infer to which object it belongs)

cheers,
