Main Component of the Project
New Single Family Residence
214 Beryl Street
Mill Valley, CA 94941
Parcel Number: 051-181-29
The applicant, Geoffrey Butler, on behalf of property owner Mark Lutzker, is requesting Design Review and Variance approval to demolish an existing 664 square-foot single-family residence and construct a new 1,597 square-foot single-family residence with a 400 square-foot attached garage on a 3,299 square-foot lot in unincorporated Mill Valley. The proposed development would have a building area of 1,997 square feet and a floor area of 1,597 square feet, resulting in a floor area ratio of 48.4 percent. The proposed building would reach a maximum height of 27 feet above surrounding grade. The house is proposed to be located 25 feet from the southeastern front property line, 5 feet from the northeastern side property line, 5 feet from the southwestern side property line, and 32 feet, 4 inches from the northwestern rear property line.
Design Review approval is required pursuant to Marin County Code Section 22.42.020.D because the project includes construction of a new single-family residence on a vacant lot that contains less than 50 percent of the minimum lot area as required by slope regulations for new lots. Variance approval is required because the project exceeds the maximum 30 percent floor area ratio established by the governing R1-B1 zoning district.
