Ventura County Concrete & Flatwork.

Flatwork concrete across LA — driveways, patios, walks, ADU slabs. Subgrade compaction, vapor barrier, #4 rebar grid, 3,000 psi mix.

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 changes about the permit here.

  1. State ADU law guarantees ministerial review on every single-family lot in the county.
  2. Coastal Development Permit may be required on Ventura / Oxnard waterfront parcels.
  3. VHFHSZ areas require Chapter 7A ignition-resistant exterior assemblies.
  4. Thousand Oaks and Conejo Valley HOAs commonly add a parallel architectural review.

What moves the Ventura County number.

  • Lower labor cost than LA city — typically 8–12% below LADBS-area equivalents.
  • VHFHSZ Chapter 7A on Conejo Valley / Ventura backcountry parcels adds $18–35k.
  • Coastal Zone CDP on Ventura / Oxnard waterfront adds $15–35k in soft costs.
  • HOA architectural review (Thousand Oaks) is fee-light but schedule-heavy.

In short.

How much does an LA driveway cost?
Broom $10–$14/sqft; stamped $18–$28/sqft. Tear-out adds $4–$6/sqft.
Will concrete crack in LA?
Yes — we cut control joints at 8–12 ft to direct cracks.
Does state ADU law apply in Ventura County?
Yes — every city in the county follows the state floor. Ministerial 60-day review, one detached ADU + one JADU per single-family lot.
Do I need a Coastal Development Permit in Ventura?
Only if the parcel is inside the Coastal Zone — generally the Ventura waterfront and Oxnard's coastal strip. Most inland parcels do not.
