Project Description
The applicant requests Variance approval to construct a 1,523-square-foot addition to an existing residence located in the unincorporated community of Kentfield. The 1,523-square-foot addition would entail a 478-square-foot upper-level addition and a 1,045-square-foot lower-level addition which includes an attached 741-square-foot accessory dwelling unit (ADU) that would be reviewed and approved through the ministerial building permit process. The 1,523-square-foot addition to the existing residence would result in a floor area ratio of 51 percent on the 4,710-square-foot lot.
The proposed addition would reach a maximum height of 26 feet, 9 inches above the surrounding grade, and the exterior walls would have the following setbacks: 30 feet from the eastern front property line; 5 feet, 6 inches from the northern side property line; 6 feet, 3 inches from the southern side property line; and 47 feet, 5 inches from the western rear property line. Various site improvements would also be entailed in the proposed development, including new attached decks, retaining walls, and a new stairway into the backyard.
Variance approval is required pursuant to Section 22.54.020 of the Marin County Development Code because the project proposes additions that would increase the floor area ratio above 30 percent on a property located in a conventional zoning district.
