Corner duplexes represent an historic housing type that is reasonably common in urban neighborhoods. They may consist of side-by-side townhomes or stacked flats. Some jurisdictions allow 2 homes on corner lots in neighborhoods where only one would typically be allowed. In others, the minimum lot size for a corner lot duplex may be less than the total minimum lot size for two stand alone homes. Oftentimes, each unit’s front door fronts a different street – which helps to maintain the appearance of a single family home from either vantage point.
