Ventura County permits run cleanly under state ADU law. Each city (Oxnard, Camarillo, Thousand Oaks, Ventura) has its own building department, but all hold ministerial review at 60 days from a complete submittal. The variables are the Coastal Zone (waterfront parcels) and Very High Fire Hazard Zones along the foothills.
What's specific to this area
☐State ADU law guarantees ministerial review on every single-family lot in the county.
☐Coastal Development Permit may be required on Ventura / Oxnard waterfront parcels.
☐VHFHSZ areas require Chapter 7A ignition-resistant exterior assemblies.
☐Thousand Oaks and Conejo Valley HOAs commonly add a parallel architectural review.
On-the-ground notes
☐State ADU law sets the floor — every city in the county runs ministerial review under it.
☐Coastal Zone parcels (Ventura, Oxnard waterfront) may add a CDP review.
☐VHFHSZ on the foothills (Ventura backcountry, Conejo Valley north) → Chapter 7A assemblies.
