Apartment over Commercial housing involves apartments located above commercial spaces, with residential units potentially occupying part of the ground floor as well. These buildings typically contain 25-100 units across 3-5 floors, with a net site density of 26-84 units per acre. Careful interior unit, building access, parking, and outdoor space design is needed to balance the residential and commercial uses and ensure safety, sociability, and livability. High density apartment over commercial developments can provide good neighborhood amenities and access to services if pedestrian environments and shared open spaces are incorporated.
