You do not need approval since there is no authority that could give it 
to you.  The requirement is only to discuss this with interested 
parties before you start.

Since there was relatively little feedback so far i had a look and it 
seems the data itself looks relatively good.  You procedure however is 
not really as it should be:

* when there are already buildings mapped you should not just delete 
them and add the new ones but replace the geometries (JOSM has a 
function for that).  This way you keep the history of the objects. 
* you plan to add quite a few buildings with additional attributes where 
there are already POI nodes at the moment which would - if you do it as 
planned - lead to duplicate features - like:


for which your buildings.osm contains a building with matching 

Since the total data volume is fairly small and most of the buildings 
are new i would recommend to do this manually, i.e. not delete the 
existing buildings all at once but go through the city block by block, 
add the missing buildings and replace the geometries of those which 
already exist while at the same time de-duplicating the POIs.
