The building:levels tag is used for marking the number of above-ground levels of a building (building=*) or part of a building (building:part=*). The underground levels and the roof do not count as levels here (see example below).
It can be useful to also add height=*, especially if the height per level is different for each building part.

Example

Example

Buildings with parts that don't start at ground level

If a building part does not start at the ground level, building:levels=* should include the number of skipped levels below the building part (i.e the number of levels that would exist if the space between the ground and the bottom of the building part were filled with levels of the typical height for this building). The key building:min_level=* should be used to describe the number of skipped levels in this building part.
