Missing-middle developments are a big problem where I live in Aurora. The town has developed the last two sections of residential land with mostly single family dwellings and relatively little row housing and a most no multi unit properties. This is a huge mistake that will come back to haunt Aurora. Single family dwellings are a costly plague on consumers, governments and the environment alike. They shouldn't be banned but the cost of building them, buying them and living in them should be prohibitive.
