Hello, highway=residential is not strictly for residential areas, but going off OSM Wiki guidelines, these do serve apartment complexes throughout this neighborhood. Alternatively, they could be tagged as highway=unclassified, which a more broad tag, but there is no difference in rendering or routing between the two tags. highway=service should not be used to tag these roads, however. Service roads with standard tags on OSM, at least in the US, are typically used for small unnamed roads which can serve a variety of areas and amenities like parking lots, rest areas, industrial areas, and so on. Roads like Copley Place and Crown Park Avenue are more akin to typical neighborhood streets rather than a road you would find in somewhere like a strip mall.
