Brush Clearance Checklist for Hillside and Canyon Homes

Owning property in beautiful hillside and canyon areas like La Habra Heights, Malibu, and Pacific Palisades offers incredible views — but it also comes with serious wildfire risks.

Cities like La Habra Heights enforce strict brush clearance standards based on the official 2024 Fire Brochure to help homeowners protect their properties and communities.


🔹 Note: While many of our examples reference La Habra Heights, the principles of brush clearance apply across Southern California’s wildfire-prone zones — including Malibu, Altadena, Pacific Palisades, Santa Monica Mountains, and hillside communities throughout Orange, Los Angeles, Riverside, and Ventura Counties.

We focus on La Habra Heights for a reason:
LHH is a wildfire-resilient city with an excellent reputation for proactive fire safety.

  • The La Habra Heights Fire Department (LHHFD) is highly regarded and is a hands-on training ground for fire science students from Rio Hondo College, many of whom go on to become firefighters throughout OC and LA Counties.
  • LHHFD’s experience, training, and brush clearance enforcement are respected across the region, making their 2024 standards an ideal model for best practices.

So whether you live in La Habra Heights or anywhere across Southern California’s hills and canyons, following these strategies will help you stay safer, compliant, and wildfire-ready.


📋 Essential Brush Clearance Checklist


🔥 Zone A: 0–30 Feet From Structures (Highly Modified Zone)

  • Remove all dead vegetation — grass, weeds, leaves, shrubs.
  • Eliminate fire-prone plants like juniper, bamboo, and pampas grass.
  • Prune trees — no branches overhanging roofs, decks, or chimneys.
  • Space plants properly to break up fuel continuity.
  • Maintain non-combustible ground surfaces (gravel, concrete) immediately adjacent to structures where possible.

🌳 Zone B: 30–100 Feet From Structures

  • Thin vegetation to create horizontal and vertical spacing between plants and trees.
  • Maintain 10 feet between tree crowns.
  • Trim lower tree limbs to ensure 6 feet of clearance from the ground.
  • Remove dead wood, brush piles, and debris.

🚪 Driveways and Access Roads

  • Clear 10 feet horizontally on each side of driveways.
  • Clear 15 feet vertically to ensure fire engine access.
  • Post reflective house numbers at least 4 inches tall, visible from the street.

🛢️ Property Maintenance Tips

  • Store firewood 30 feet away from structures.
  • Move propane tanks safely away from homes.
  • Keep roofs and gutters free of leaves and debris year-round.
  • Regularly inspect for new weed growth after rains.

🛡️ Bonus: Ongoing Upkeep Matters

Brush clearance isn’t just a one-time spring cleaning.

  • Check regrowth monthly during fire season (June–October).
  • Clear after high winds, rains, or heatwaves.
  • Keep defensible space maintained year-round to stay safe and pass inspections.

Avoid common mistakes that can still get you fined.
