Zoning
MDR
Medium Density Residential Zone
The MDR zone is intended for areas appropriate for multi-unit dwellings and is suitable near activity centers and along major thoroughfares. This zone allows for a variety of residential opportunities including small single unit dwellings, row houses, townhomes, and small apartment complexes. The allowable density ranges from 8 to 16 dwelling units per acre. The MDR zone is consistent with the Medium Density Residential MDR and Mobile Home Park MHP land use designations in the General Plan.
