But in recent decades, it was typically a 2-story house, often a duplex, like what used to be on the block where that fragile stick atop heavy-steel-reinforced pad monstrosity across from the Renaissance Center… between… Macomb & Copeland/Strong “park”, Virginia & Carolina. 11 or 12 were built there in the 1990s. Interesting; 2 different map widgets still show the old town houses that haven’t been there for years, with the Obummer creating jobs sign for a couple years. But a third shows the “new” monstrosity carefully designed with a parking garage in the Western middle open to the local solar furnace effect. “Brilliant” and cheap, like a WM or Target apartment building.

Anyway, these carriage houses/ADUs/ granny-apartments are a fairly good idea economically in our current over-crowded circumstances. They are not “sheds”… a couple steps up from that, up from the micro- and mini-house craze, with, as discussed, plumbing & electricity, heating and usually A/C. OK, I once knew a doctor whose pool house was about ADU size, but then his main house was somewhat super-sized, so it would have passed the rule.

Why would Townhomes be listed as an ADU, they are not Accessory Dwelling Units? ADU’s are Sheds, Detached Garages and Pool House type Structures. Leave it as is.
