Does Brentwood require a permit?

Yes — LADBS reviews this scope.

foundation in Brentwood is permit-required. LADBS (City of Los Angeles) reviews the package; the building permit covers the work, additional overlays may add CDP, fire, hillside, or historic review on top.

What LADBS actually reviews.

LADBS (City of Los Angeles) runs plan check on every foundation project at this scope. Full plan-check cycle (2–3 rounds of corrections is typical) — expect 6–14 weeks from submittal to issued permit. VHFHSZ parcels trigger Chapter 7A exterior-assembly review. Hillside-overlay parcels need grading-quantity and haul-route sign-off.

Brentwood treats foundation as standard permitted work — the permit set scope follows the project scope and the LADBS (City of Los Angeles) fee schedule.

Estimated review timeline: 10–20 weeks to issued permit, including 2 overlay reviews plus LADBS (City of Los Angeles) plan check.

Documents the foundation permit package needs.

  • Engineered foundation / retrofit plan set, wet-stamped
  • Soils report or geotechnical letter
  • Structural calcs and anchor schedule
  • LADBS (City of Los Angeles) structural permit application
