Medium Density Residential (MDR) District

3.3.4.

Medium Density Residential (MDR) District

A. Purpose

In accordance with the Comprehensive Plan, the Medium Density Residential District accommodates neighborhoods with a variety of housing types and a net density between 4.5 and 7.5 dwelling units per acre. It is suitable for infill development in established neighborhoods, for development of areas identified as medium density residential in the Comprehensive Plan, or areas suited to medium density development supported by adequate infrastructure and nonresidential land uses. The regulations of this district are intended to allow innovation in the arrangement of buildings within such developments and discourage the development of land uses that could substantially interfere with, or be detrimental, to residential character.
