single household?

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)

If you perform a survey you would usually see it (2 postboxes etc.) --Dieterdreist (talk) 16:55, 30 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)

Family names

Sometimes family names are seen on houses, "The Williamsons", "廖寓", etc.

Rather than use name= in such cases, see Talk:Key:inscription#Chinese_Tanghao_.28.E5.A0.82.E8.99.9F.29 instead. Jidanni (talk) 13:30, 19 July 2020 (UTC)


Add examples of valid name= tags. Probably these:

House naming started many years ago with rich people naming their homes. The rich named their Halls, Houses, Manors, Castles, and Lodges according to ancestry, location, and family titles: Norfolk House (Duke of), Belvoir Castle (overlooking the Belvoir Valley); Castle Droge (named after a 13th ancestor) etc. Gradually over the years other people began to give names to their homes too.

All houses in towns and cities have a number. Very few have just a name and majority do not have names. [1]

And not "37 Nurdsford Road" which is more properly just an address. Jidanni (talk) 22:21, 25 September 2020 (UTC)

Addition of house=*

The page was recently added to mention that house=* (house=detached, house=semi-detached etc) is sometimes added to building=house instead of using building=semidetached_house , building=detached etc.

However, that tag is not widely used and about 90% of uses are in Ireland: see and - in most countries the tags like building=detached are 100 to 1000 time more common:

So perhaps house=* is not common enough to be mentioned on this page. --Jeisenbe (talk) 15:46, 24 December 2020 (UTC)

It not being in use as much doesn't mean it shouldn't be mentioned. house=* has 96,732 uses and I think having it documented would be worthwhile. --GoodClover (talk) 11:56, 25 December 2020 (UTC)
Certainly it is a good thing that it is now documented at Key:house and the tag pages like Tag:house=detached - thank you for that. But I question whether it is used widely enough to mention on this page, Tag:building=house - in Ireland it is used on 16% of houses so it's worth mentioning on local pages for that country, but in other countries it is used with less than 0.05% of houses (one out of every 20,000 building=house features) so this is very rare in other places. --Jeisenbe (talk) 00:34, 26 December 2020 (UTC)
Maybe just remove the table? I agree that having that here is probably too much. --GoodClover (talk) 12:37, 26 December 2020 (UTC)
I've gone ahead and done that. --GoodClover (talk) 12:39, 26 December 2020 (UTC)

Inferring More Specific Options

Can a well-tagged building=house be as good as tagging a more specific housing option (e.g. building=bungalow)? For the bungalow example, if a building has building=house and building:levels=1 (and possibly has no adjoining nodes) does it not have all the properties that may be inferred from building=bungalow? As such should there be some explanation on this page explaining what additional tags, when included in the same building as building=house, make an equivalent "more specific" example? - Coolmule0 (talk) 06:24, 15 April 2021 (UTC)
