Oooops… I completely missed the townhouse part. TemekuT is correct. Townhouses aretypically built just like condos. The builder may take 3 or 4 parcels, create one large lot, and then build 8-10 townhouses. Townhouses done like this are considered condominiums legally, with a couple of exceptions for 0 lot line stuff like what they have done in Little Italy with the “row homes”.
