does not work really in this case:
- There is no "roof" depending on he direction  from which you appraoch. It
may look like a building with a roof from one side, but from the opposite
it looks, as if your are entering onto a park
- It looks and is used as leisure=park

Is it best to just tag the part of the roof that is a green roof with
> landuse=grass?

What about two polygons with landuse type of tags on different layers
the commercial/garage layer:
landuse=commercial
layer=0
the park layer:
leisure=park
layer=1
This would be in analogy to how we tag street or railway tunnels (thanks
for pointing out the missing layer on the tunnel and the building_passage
tag value, which I did not know)

But if we consider it as a building we would need to use the 3D tagging
approach with levels.
