On September 24, 2015, the Marin County Deputy Zoning Administrator (DZA) approved with conditions Coastal Permit 2015-0161 authorizing construction of a new 3,651 square foot single-family residence, which included an attached 528 square foot garage, in addition to new site improvements including a rear patio and terrace, a new septic system, and landscaping. The existing 540 square foot “barrel house”, located in the central portion of the property, was proposed to remain as storage. Condition of approval 2.c stated:
“The Building Permit plans shall reflect that the “barrel house” septic system is being decommissioned and that any kitchen and bathroom facilities in the “barrel house” are being removed.”
The applicant requests an amendment to modify the Hancock Coastal Permit to legalize the conversion of the “barrel house” to an accessory dwelling unit and reconnect to the existing septic system by an existing septic pipe. The existing barrel house structure was constructed legally, is 17.5 feet in height above grade, and located more than 100 feet from all property lines.
A Coastal Permit amendment is required to modify the 2015 conditions of approval for the Hancock Coastal Permit.
