What I do to avoid most redundancy, is to create an associatedStreet relation. So the house only needs a housenumber and maybe a housename and all the rest of the information is on the relation. (addr:country, addr:city and addr:postcode). I add more than one street to them though, even if JOSM complains about that. I only create a different one for the same street if this street crosses city limits or when a change of postal code occurs.
There is still some redundancy, since postcode, city and country are repeated in all these relations, but it's already far better, than to have that information on each and every house.
