Comment (by lonvia):

 This is tricky because there are three objects involved in the
 computation. First, Nominatim has to figure out that the fire station node
 is inside a building and then that there is also a house number node in
 the building that might be related. It gets even more tricky if there are
 multiple house numbers. Then it would have to find all of them and decide
 which one is closest. All not impossible but unlikely to happen in the
 near future.

 One thing does already work, though: if the house number is tagged on the
 building outline, then all POIs inside (including that fire station in the
 example) will inherit that house number if they don't have already one of
 their own.
