How do you map multiple attached building objects?

0

This is related to the question:

https://help.openstreetmap.org/questions/36574/how-do-you-map-and-tag-a-screened-porch?

In that question they answered that porches could be tagged with building:porch. With that in mind, how should I tag two building that share a wall with each other.

This also comes up in things like row homes and some building in commercial areas. The validator complains if I have a building that is an unclosed way, so I am assuming that I can't just make a building that only has three sides and shares its forth side with another building.

talking of two four-sided buildings which share a wall:

The usual way: just let them share two nodes. Each four sides and one side of each uses the same nodes than the other building. Example https://www.openstreetmap.org/way/145005615

If you do not really know the inner walls of a quite uniform (outside) big building, then rather just map it as a single building with possibly several housenumber nodes (if it has several numbers). If it is terraced houses, then building=terrace would be the tag to use on such a way.
