Project Description
The applicant is requesting Coast Development Permit approval to demolish an existing 170 square foot shed and construct a new 485 square foot detached Residential Accessory Dwelling Unit on an improved lot in Muir Beach.

The proposed project would also entail 66 cubic yards of cut and 66 cubic yards of off haul.
