 Article 8. MIXED USE DISTRICTS

  § 840. MUG - MIXED USE-GENERAL DISTRICT.  

Latest version.
  • The Mixed Use-General (MUG) District is largely comprised of the low-scale, production, distribution, and repair (PDR) uses mixed with housing and small-scale retail. The MUG is designed to maintain and facilitate the growth and expansion of small-scale light manufacturing, wholesale distribution, arts production and performance/exhibition activities, general commercial and neighborhood-serving retail and personal service activities while protecting existing housing and encouraging the development of housing at a scale and density compatible with the existing neighborhood.
    Housing is encouraged over ground floor commercial and PDR uses. New residential or mixed use developments are encouraged to provide as much mixed-income family housing as possible. Existing group housing and dwelling units would be protected from demolition or conversion to nonresidential use by requiring conditional use review. Accessory Dwelling Units are permitted within the district pursuant to subsection 207(c)(4) of this Code.
    Nighttime entertainment, movie theaters, adult entertainment and heavy manufacturing uses are not permitted. Office is restricted to the upper floors of multiple story buildings.
