I wonder if the single household should be a strict requirement. In some contexts it might well be possible that a house has a granny-flat as part of it, defacto leading to 2 households, of which one could be considered "minor" (other than grannies, this kind of small apartment is often rent to students or other 1-2-person households). --Dieterdreist (talk) 12:17, 26 November 2015 (UTC)
- I think that single household is not a strict requirement. I wonder how we could map those houses if it would. Would we conduct a survey who is living there? ;-) Chrabros (talk) 07:09, 27 November 2015 (UTC)
- What about duplexes where a building has two (and no more than two) completely separate living quarters? They often have separate addresses but will sometimes be addressed as A & B. They are common in the US. I have been mapping them as building=house and then placing two markers for the addresses.
As far as I understand, a duplex might be not only one building but two sharing one wall? It depends on the case maybe? (I'm not an English native and I have found several translations that suggest that both cases exist). I guess I would use a distinct building type for those (maybe building=duplex? There are currently 4853 of these in the db). --Dieterdreist (talk) 12:12, 12 February 2016 (UTC)
