When you don't pull a CA and let things grow organically there isn't much of a discontinuity so you don't get much development like that. It'll be a gradual increase from SFH in the exurbs with more and more mutlifamily and small apartment buildings increasing in density to the city core where it's basically all purpose built apartment buildings with dozens of units at a minimum.

A neighborhood that's got a lot of 2/3/4 family homes feels about the same as a SFH neighborhood if those homes have one unit occupied by the owner.
