California unincorporated profile
Outside the boundaries of incorporated cities and towns, the Monterey County government is the planning and permitting lead agency. That means county zoning, county building codes, and county environmental review apply directly — without a separate city layer. The county rules most likely to catch a project applicant off guard are listed below.
These Monterey County rules apply directly to projects in unincorporated areas of the county, with no city-level overlay.
Oak removal permits are required in several designated planning areas of the county — and in agricultural zones, there's also a minimum canopy retention rule that applies even when individual tree removal is otherwise allowed.
Development in the Big Sur coastal zone is subject to one of the strictest Local Coastal Programs in California; even minor modifications to existing structures may require a Coastal Development Permit.
Portions of the former Fort Ord military base still contain unexploded ordnance and soil contamination — projects on or adjacent to those areas face environmental due diligence requirements that can significantly complicate an otherwise routine development.
The Big Sur coast and Carmel Valley are mapped in the state fire hazard zone; defensible space and fire-resistant construction standards apply here even in areas that feel remote and lush.
