OSM Tag History
The
building:levels
tag is used for marking the
actual
number (see
value section
) of above-ground non-roof levels (= floors = storeys) of a building (
building
=*
) or part of a building (
building:part
=*
). The underground levels and the roof do not count as levels here. However, levels that are part-way underground do count (see example below).
It can be useful to also add
height
=*
, especially if the height per level is different for each building part. Keep in mind that
height
=*
includes the roof, while
building:levels
does not.

Examples
Ground level (
level
), first floor, (
level
) + second floor, (
level
) counts as
building:levels
Underground level (
level
-1
) counts as
building:levels:underground
A roof level (
level
) counts as
roof:levels
A building (part) with only one ground level will be tagged with
building:levels
A building full in the ground (for example an archeological tomb like at
Tierradentro
) will be tagged with
building:levels
building:levels:underground
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.
It is therefore imperative that
building:levels
=*
is always strictly greater than
building:min_level
=*
Values
Values should be a positive
integer
number. Fractional values (like
1.5
) are
not valid
(what is the meaning of a 0.5 floor?) and probably means that the mapper diverted the tags *:levels to express a height instead of using the appropriate tags. The usual dimension is a height of
3 meters
for each floor (default floor height used for 3D renderings when the height tags are not specified). Use height and roof:height if a building has unusual dimensions. For example, use
building:levels
and
height
4.5
if the building has one 4.5 m high floor instead of
building:levels
1.5
The height of buildings (in meters) is usually difficult to determine if there is no right data, e.g. from a cadastre. But the default value of 3 meters for one floor is probably a good approximation of the actual height, if you don't know it, for most of the buildings. So you don't need to add the height tags for a normal 4-storey building. If floors are clearly larger or smaller than the default value (for example a sport hall 6 meters high, or a small shelter 2 meters high, or a 4-storey retail building higher than a 5-storey residential building), use the tags
height
=*
or/and
roof:height
=*
For a better understanding, see
Simple_3D_Buildings#Usage_of_height,_roof:height,_building:levels,_roof:levels
The number of levels is a relative value – you know only how many levels a building has and when drawing
building:parts
, you give their relative number of levels in relation to the whole building.
