Zoning (Ordinance) Updates

Zoning and subdivision regulations are contained in Title 20 "Zoning" of the City's Mill Valley Municipal Code.  The "Zoning Code" primarily governs the development and use of property in Mill Valley, and also establish the procedures by which the City reviews and makes decisions on applications for residential and commercial design review, conditional use permits and variances.
