This tag describes the number of residential units (flats, apartments) in a building.

It is very similar to building:flats=* which Key:Building recommends the use of in line with the terminology of addr:flats=* and the general preference towards British English for tags and wiki.

As of 2016, the vast majority (>99.8%) of uses of this tag came from the Los Angeles County, California, building import in which it was specifically defined as the number of living units. An apartment building with 5 apartments would have building:units=5.
