Maybe less now. It used to. Look at cities like London (UK, not Ontario), and you'll see lots of "mews" (1) that are rows of stables with associated housing for servants tacked onto the back of large housing and backing onto "service streets", so the rich could have their horses and servants housed where they were needed.

Today, of course, most mews have been converted into expensive standalone housing units, and most new integrated neighbourhoods are the result of council planning offices.
