A building:flats=* key contains a number of residential units (flats, apartments) in an apartment building (building=apartments), residential building (building=residential), house (building=house), detached house (building=detached) or similar building. Note that this is a quantity (e.g. 4) rather than the individual numbers of the apartments (e.g. 101;103;105, for which the tag addr:flats is used instead).
Often this can be surveyed without entering the premises by counting the number of letter boxes for numbered flats.
