|Tools for this tag|
This tag can be used in addition to building=house to map the outline of a row of houses which form a terrace. Each of the dwellings normally has its own entrance. These are known as "rowhouse" or "townhouse" in North American English.
Use of this tagging scheme is discouraged, mapping the individual units in a terrace is preferred.
Terraced vs Terrace
Mapping a row of terraced houses (which have not been mapped as adjoining individual units) as building=terrace is much more common. This approach is preferred by some mappers, since a row of terraced houses is not, by definition, a house. This is also the current default approach to tagging a row of terraced houses in the iD editor.
There are many ways of mapping terraces, these can be seen of the wiki page Tag:building=terrace.
How to map
Draw a single area along the outline of the whole terrace. Optionally add entrance=* for each entrance. If the borders of each unit in the terrace is known, then it is preferred to instead map the individual units separately and tag them with house=terraced.
