Medium Density
Multiplex
Form: A single two to two and a half story building with five to 12 units. Units may be stacked or side-by-side.5
Local presence: Multiplex medium multifamily buildings can be found throughout Chester County, predominately in Boroughs.
Zoning considerations: Multiplex medium developments do not have rear yards and will require lower setback minimums for development. Additionally, multiplexes may require a minimum allowance of 12 dwelling units per acre.
