Wildfire Home Hardening in Calabasas, California.

Calabasas is a Very High Fire Hazard Severity Zone. When the Woolsey Fire jumped the 101 at Liberty Canyon, embers, not flames, ignited homes through vents and eaves. We install ember-resistant vents, mesh, gutter guards, and fencing built to California's Chapter 7A wildfire code and hand you a documented, insurance-ready risk assessment.

Why Calabasas Is at Risk

Where the embers come from, and how they get in.

Calabasas is wedged into the Santa Monica Mountains where dry chaparral, steep slopes, and offshore Santa Ana winds line up almost every fall. Fire behavior here is not slow ground creep. It is wind-driven ember cast that can travel more than a mile ahead of the visible flame front and land on rooftops, in gutters, and inside attic vents blocks from any burning fuel.

CAL FIRE rates almost every parcel in the 91301 and 91302 ZIP codes as a Very High Fire Hazard Severity Zone. The state map adopted in March 2025 expanded Very High and High designations across Los Angeles County, and the tier a home sits in now drives Chapter 7A retrofit expectations and Public Resources Code section 4291 defensible-space requirements for the first 100 feet around the structure.

Standard louvered vents were built for airflow, not fire. In the Woolsey Fire on November 8 2018, homes across Calabasas ignited from the inside out after embers slipped through attic, eave, and foundation vents. Insurers have been non-renewing policies in Very High zones for years, and the document carriers keep asking for is a written record of ember-resistant hardening on those openings.

Who You Hire Matters

In a Very High fire zone like Calabasas, your installer matters.

The Handyman

Often, not insured at all.

  • No coverage if something goes wrong on your roof or in your attic.
  • Not trained for ladder and roof safety or attic airflow.
  • No documentation for your insurer.

Other Contractors

Insured for general work, not this.

  • Generally insured for general contracting, but not for specialized vent, roof, and fireproofing work.
  • Wildfire hardening is a side job, not their focus.
  • Documentation, but not built around fire code or your insurer.

EmberSafe Home

Insured directly for this work.

  • Insured specifically for home hardening: installing hardening products, ladder work, and roof systems.
  • We fit the right listed ember-resistant vent to each opening, from multiple manufacturers.
  • Installed to California code (Chapter 7A), documented for your insurer. It is all we do.

Insurance & Incentives

Insurance carriers and the state are actively requiring resiliency and retrofitting.

In Calabasas, insurers keep non-renewing homes and pushing owners onto the state FAIR Plan, and the rules only tighten from here. Hardening and defensible space are already part of staying insurable, and California requires insurers to offer mitigation discounts for the work. Homeowners who harden now get ahead of it, better insurance standing and a head start before local mandates land. We cannot promise coverage, but waiting is the riskiest move of all.

AB 3074: the Zone 0 law

AB 3074 created Zone 0, the ember-resistant zone in the first 5 feet around your home, the space that starts most home fires. The statewide rules are still being finalized, but local jurisdictions are already moving to adopt and enforce them. Harden now and you get ahead of the mandate instead of scrambling under a deadline, when costs rise and crews book out. Clear the first 5 feet of mulch, firewood, and wood fencing touching the house before it is required.

AB 38: wildfire disclosure at sale

Selling in a Calabasas fire zone means disclosing your home's fire-vulnerability and defensible-space status during escrow, and buyers and their insurers now scrutinize it. Hardening before you list keeps the disclosure clean and protects your sale.

Chapter 7A: how the house is built

Ember-resistant vents, windows, siding, and roofing come from California's building code, Chapter 7A. That is the standard we install to.

Rebates and mitigation discounts

Mandated insurer mitigation discounts, plus new state grants for fire-safe roofs and Zone 0 work. These programs are new and can change or run out. We flag what Calabasas homes may qualify for and document the work so you can claim it.

FAQ

Common questions from Calabasas homeowners.

Is my Calabasas home in a fire hazard zone?

Almost certainly yes. CAL FIRE rates the majority of Calabasas (both 91301 and 91302) as a Very High Fire Hazard Severity Zone on the state map adopted in March 2025. That is the top hazard tier and it drives Chapter 7A construction and retrofit standards for hardening work.

Does California code require ember-resistant vents in Calabasas?

For hardened work in a Wildland-Urban Interface Very High zone, yes. Chapter 7A of the California Building Code requires exterior vents to be ember- and flame-resistant, and screens must reject embers in the 1/16 to 1/8 inch range. Ember-resistant mesh over existing openings is the lowest-cost first pass; listed replacement assemblies are the full retrofit.

What did the Woolsey Fire teach us about vents?

On November 8 2018, the Woolsey Fire crossed U.S. 101 near Liberty Canyon and ran through the Calabasas hills. Post-fire reviews found that most of the homes lost in Calabasas ignited from the inside out after wind-driven embers entered attic, eave, and foundation vents, not from direct flame contact. The single highest-leverage retrofit for a Calabasas home is closing those openings.

Will hardening my home help with insurance?

Ember-resistant vents and mesh are recognized under California's Safer from Wildfires framework and a growing number of carriers ask to see documented hardening in Very High zones. We hand you before and after photos and a written summary. The carrier makes the final discount, binding, or renewal decision, so we cannot promise a specific insurance outcome.

Do you harden every opening or just some?

You choose the scope during your free on-site risk assessment. Most Calabasas homeowners start with the highest-risk openings on the wind-facing elevations and then work through the rest of the vents, gutters, and fence lines. We scope every opening in writing so you can phase the work.

Are you licensed and do you work in gated communities?

Yes. EmberSafe Home is Cal Building Group, Inc., CSLB License #1139619, licensed and insured in California. We install listed ember-resistant vents from BrandGuard, Vulcan, and FireStorm, and we work in gated and master-planned communities across Calabasas, including The Oaks of Calabasas, Calabasas Park Estates, and adjacent Hidden Hills.
