Then it's mistakenly tagged. You do not use `building=detached` for shops and offices. Per the wiki, https://wiki.openstreetmap.org/wiki/Tag:building%3Ddetached <https://wiki.openstreetmap.org/wiki/Tag:building%3Ddetached>

> A detached house is a free-standing residential building usually housing a single family. Known as a/single-family home/in the United States, a/single-detached dwelling/in Canada, a/separate house/in New Zealand and/Maison individuelle/in France.

It includes the _function_ of the building.

Strictly speaking, building=* is about the building's original function inasmuch as it influenced the building's construction, whereas building:use=*, a much less common key, closely reflects the building's current occupants. A building=detached could very well be functioning as a nonresidential dentist's office or insurance agency.

This distinction is not very evenly applied in practice. For example, many modern American church buildings are architecturally indistinguishable from commercial buildings or retail storefronts, but many get tagged as building=church anyways, because there's so much variety in religious architecture anyways. Some renderers like osm-carto infer prominence from building=church, befitting a boxy Texas megachurch without a steeple that nonetheless dominates the surrounding neighborhood.

Similarly, a layperson may find it difficult to discern that a detached house was long ago converted from a firehouse, so they tag it as building=detached instead of building=fire_station. But in some places, mappers have been more rigorous about respecting each building's architectural origins.
