Addresses are not extracted (yet) from the vector cadastre data.
Adding them is done 100% manually except when other opendata sets are
available (Nantes metropole has just been finished with 400.000+
addresses added if I'm not wrong).
We have the cadastre JOSM plugin who helps adding addresses manually
using the cadastre WMS layer in the background.
I manually added thousands of addresses that way, on both WMS vector
based cadastre and raster one (more difficult to read).
