Project Description

The applicant is requesting Design Review approval for the following: (1) to construct 913 square feet of additions onto an existing 2,142 square-foot single-family residence; (2) to install a new, raised roof onto the existing residence; and (3) to construct a new 1,199 square-foot attached accessory structure (accessory dwelling unit) on a developed lot in unincorporated San Anselmo. The 2,112 square feet of proposed new development would result in a floor area of 4,823 feet square feet and a floor area ratio of 18.5 percent on the 26,107 square-foot lot.

The proposed roof of the existing residence would reach a maximum height of approximately 21 feet, 11 ¾ inches above surrounding grade. The exterior walls of the additions onto the existing residence would have the closest setbacks to the property lines as follows: 25 feet from the northern front property line; 10 feet, 8 ½ inches from the eastern side property line; 76 feet from the western side property line; 42 feet, 10 ¼ inches from the southern rear property line.

The proposed attached accessory structure (accessory dwelling unit) would reach a maximum height of 18 feet, nine inches above surrounding grade and the exterior walls would have the following setbacks: 100 feet from the northern front property line; 92 feet from the eastern side property line; 23 feet from the eastern side property line; and over 27 feet, 10 inches from the southern rear property line.

Design Review approval is required pursuant to Marin County Development Code (MCC) Section 22.42.020.B. because the project would result in a floor area exceeding 3,500 square feet. Design Review approval is required pursuant to MCC Section 22.54.045.E because a portion of the roof proposed to be raised encroaches into the 25-foot front setback required by the governing R1-BD zoning district.
