DescriptionA medium-to-large sized (1 to 3.5 story) detached structure consisting of multiple side-by-side and/or stacked dwelling units oriented around a courtyard or series of courtyards. The courtyard replaces the function of a rear yard and is more open to the street in low intensity neighborhoods and less open to the street in more urban settings. Each unit is accessed from the courtyard and shared stairs each provide access up to 3 units.
