The applicant requests Design Review approval to remove an existing swimming pool and construct 306 square feet of additions to an existing 400 square-foot detached accessory structure on a developed lot in unincorporated Kentfield. The proposed development would result in a building area of 3,453 square feet and a floor area of 3,053 square feet which would result in a floor area ratio of 14 percent on the 21,986 square-foot lot. The proposed addition to the detached accessory structure would reach a maximum height of 15 feet above surrounding grade, includes a new upper roof deck, and is proposed to be located approximately 28 feet from the southern front property line; 11 feet, 6 inches from the eastern side property line; and over 100 feet from the western side property line and northern rear property line.
Design Review approval is required pursuant to Marin County Code Section 22.20.090.1.B because the addition to the detached accessory structure is located 28 feet from the front property line and 11 feet, 6 inches from the side property line where setbacks of 30 feet and 15 feet, respectfully, would otherwise be required by the R1-B3 zoning district.
