The applicant requests Variance and Design Review approval to construct 991 square feet of new additions onto an existing 4,482 square-foot single-family residence and a new 775 square-foot detached accessory structure (garage) on a developed lot in unincorporated Kentfield. The 1,766 square feet of proposed new development would result in a floor area of 6,419 square feet and a floor are ratio of 10.68 percent on the 60,131 square-foot lot.
The proposed additions onto the existing residence would reach a maximum height of approximately 16 feet, 10 inches above surround grade and the exterior walls of the additions and areas of addition and remodel would have the closest setbacks to the property lines as follows: 40 feet from the northern front property line; 0.5 inches from the western side property line; 68 feet from the eastern side property line; 84 feet, 8 ½ inches from the southern rear property line.
The proposed detach accessory structure (garage) would reach a maximum height of twelve feet, eight inches above surrounding grade and the exterior walls would have the following setbacks: 14 feet, three inches from the northern front property line; 46 feet, 6 ½ inches from the western side property line; 38 feet from the eastern side property line; and over 100 feet from the southern rear property line.
Various site improvements would also be entailed in the proposed development, including an improved driveway and new hardscape.
Variance approval is required because the proposed project does not meet the setback standards for the R1-B3 zoning district, pursuant to Marin County Development Code Section 22.14.050. Design Review approval is required because the project entails the construction of a detached accessory structure in the required 30-foot front yard setback per the R1-B3 zoning district.
