I have added the address to this building. For the other buildings, I suspect we can copy the numbers from the official Los Angeles data portal, I am not completely sure if that is allowed, but I'll try to find out.

Regarding the area name: I am not a local, so I can't say how well known that name is or if it should be on the map. If you think it should be on the map, I can add it. What exactly is the extent of this area?
