What to Watch Out For
- Pacific Palisades is within the City of Los Angeles — LADBS rules apply.
- Large portions of the Palisades are in the Coastal Zone — a Coastal Development Permit (CDP) may be required.
- Entire community is designated VHFHSZ — Class A roofing, ember-resistant vents, and 100-ft defensible space are mandatory.
- Post-Palisades Fire (Jan 2025): many parcels are in the fire rebuild zone — expedited review pathways may be available under emergency ordinances.
