The applicant requests Design Review and Accessory Dwelling Unit Permit approval to construct a 586 square foot accessory dwelling unit to the understory of an existing single family residence in unincorporated Mill Valley. The existing floor area is 2,386 square feet. The proposed development would result in a floor area of 2,972 square feet. Therefore, the proposed development would result in a floor are ratio of 10 percent on the 28,800 square foot lot. The height of the building would not be changed. The proposed development would have the following setbacks: 12 feet from the northern side property line; 28 feet from the front property line; 6 feet from the southern side property line; 148 feet from the western rear property line.
Design Review approval is required because the project is the planned zoning district. Accessory Dwelling Unit Permit is required because the accessory dwelling unit would entail new construction.
