Also, you didn't split these houses. Use the terracer plugin to this, and look for gardens in the backyard. Where you see a fence is where one house ends and another starts. 

Once you have split them, you can add building=house tags and addr:street tags (if you are sure of the street).

I have written a guide on how to draw buildings (and split them, add tags, etc..) here:
