San Mateo County Board of Supervisors and Planning Commission process use permits, general plan amendments, grading permits, and coastal development permits under CEQA review. The unincorporated county areas along the San Mateo coast — including Half Moon Bay's periphery, Montara, and Pescadero — involve California Coastal Commission coordination for development in the coastal zone. The Emerald Hills, North Fair Oaks, and Devonshire Canyon neighborhoods generate residential subdivision and use permit filings. Tech campus expansions in Menlo Park and Redwood City's unincorporated pockets drive office and R&D entitlement applications. County housing element compliance and RHNA requirements for unincorporated areas are increasing multifamily development proposals.
