Residential development in the RU-4 District allows a variety of housing types including single-family attached (townhouse) and multifamily (large home, stacked townhouse, apartment). New RU-4 districts are generally located in an infill or redevelopment location where similar housing types are part of the original fabric of development. Additionally, RU-4 districts should have a shared street network with and are generally located within 500 feet of a CMU-3, or CBD district or are within 500 feet of an arterial.
