In many parts of California, particularly hillside communities, canyon corridors, and wildfire-prone regions, home insurance is no longer a backend administrative task addressed after design and pricing. It has quietly become a primary design constraint.
This shift directly affects how custom homes are planned, detailed, and built in high-risk fire zones. It aligns with how we approach custom residential projects at Bur Oak Building Co., where performance, risk, and constructability are considered together from the start through our custom home building services.
The January 2025 wildfires in Pacific Palisades and Altadena made this reality impossible to ignore. These were not abstract risk scenarios. They were market-moving loss events that materially reshaped how insurers, regulators, lenders, and homeowners evaluate wildfire exposure.
How the Palisades and Altadena Fires Changed California Home Insurance
The Palisades and Eaton (Altadena) fires collectively destroyed thousands of structures across Los Angeles County and resulted in tens of billions of dollars in insured losses. These events placed unprecedented strain on an insurance market that was already tightening due to cumulative wildfire exposure.
In the aftermath, insurers accelerated actions that were already underway:
Reduced policy availability in high-risk zones
Tighter underwriting criteria
Coverage caps well below replacement cost
Emergency rate increases and revised eligibility standards
In areas like Pacific Palisades, where rebuilding and wildfire resilience are now inseparable, insurance constraints have become a central factor in how reconstruction projects are evaluated and planned. This is why rebuilding in Pacific Palisades now requires insurance-aware planning rather than treating insurance as a post-design step.
The result is a new reality: many homes that can be legally designed and built cannot be insured adequately under traditional policies.
How Wildfire Risk Is Affecting Home Insurance in California
Even before the 2025 fires, several major insurers had limited or ceased writing new homeowners policies in wildfire-exposed areas. After the Palisades and Altadena losses, this trend intensified.
For many homeowners, the only remaining option is the California FAIR Plan, a last-resort insurer that provides basic fire coverage but often caps limits far below actual replacement value. Supplemental or excess policies may be required to close the gap, if they are available at all.
This shift has made wildfire risk a design-time consideration, not an administrative afterthought—and it has direct implications for how homes are planned, detailed, and approved.
The Insurance Gap Facing High-Value Homes in California
For custom and high-value homes, the consequences are significant.
It is increasingly common to see:
Homes with $10–20M replacement values
Primary policies capped at $2–3M
Excess coverage that is conditional, expensive, or unavailable
This creates an insurance gap—a portion of the home’s replacement cost that is effectively uninsured.
Most homeowners discover this gap far too late:
After architectural design is complete
After construction pricing is finalized
During escrow, when flexibility is limited
At that point, options narrow quickly: redesign, delay, self-insure catastrophic risk, or proceed underinsured.
Why Home Design Now Plays a Direct Role in Insurance Coverage
Insurers and specialty risk-mitigation providers are no longer evaluating homes based solely on location or square footage. They are increasingly focused on how a home performs during a wildfire event.
Key factors now influencing underwriting decisions include:
Ember intrusion resistance
Continuity of the building envelope
Roof, eave, and soffit detailing
Vent design and protection
Window assemblies and opening protection
Site access and on-site water availability
These principles are foundational to building science–driven home design, where assemblies and systems are evaluated for real-world performance—not just code compliance.
This is also where a major misconception appears: many homeowners assume that passing inspection guarantees protection, when in reality, code compliance does not necessarily translate to insurability or survivability. We explore this gap directly in our follow-up article, Why Code Compliance ≠ Insurability in California Homes.
Wildfire Risk Mitigation Strategies That Go Beyond Code Requirements
California building code establishes minimum life-safety standards. It does not ensure a home is resilient—or insurable—in extreme wildfire conditions.
In higher-risk zones, additional mitigation strategies are increasingly part of serious planning discussions, including:
Enhanced perimeter and envelope hardening
Integrated water storage and delivery strategies
Automated or semi-automated suppression concepts
Fire-retardant material assemblies
Landscape design as a functional fire-response system
We regularly expand on these concepts, along with wildfire resilience, material selection, and performance-based detailing, through our building science and wildfire resilience blog.
The Costly Mistake of Addressing Insurance After Design
One of the most common—and expensive—mistakes in wildfire-exposed projects is sequencing.
Traditionally:
The home is designed for aesthetics and code compliance
The builder prices what is drawn
Insurance is addressed afterward
In today’s environment, this approach is backwards.
When insurance constraints surface late, meaningful changes are disruptive, costly, or impossible. The most resilient projects address risk early—whether for new construction or high-end remodels in fire-prone areas.
How the Role of the Builder Is Changing in High-Risk Fire Zones
In this environment, the builder’s role extends beyond execution.
A capable builder must:
Identify wildfire and insurance risk early
Coordinate between architect, engineer, and consultants
Translate abstract risk concepts into buildable assemblies
Ensure decisions are made early, before constraints become liabilities
This level of coordination and accountability defines how we operate at Bur Oak Building Co.—as a strategic partner throughout the design and construction process.
Who This Matters For: Rebuilds, Hillside Homes, and High-Risk Properties
These issues are most acute for:
Hillside and canyon properties
Homes in Wildland–Urban Interface (WUI) zones
Rebuilds following fire events
High-value custom homes where replacement cost exceeds standard policy limits
Realtors navigating escrows impacted by insurance availability
If any of these apply, insurance should be part of the design conversation—not an afterthought.
Frequently Asked Questions About Wildfire Insurance in California
Q. Can you insure a home in a high-risk wildfire zone in California?
Yes, but options are increasingly limited. Many homeowners in wildfire-prone areas are pushed into last-resort or specialty policies with capped limits, exclusions, and higher deductibles. In many cases, insurability depends not just on location, but on how the home is designed, detailed, and built—particularly for custom homes in high-risk fire zones.
Does home design affect wildfire insurance coverage?
Yes. Insurers increasingly evaluate how a home performs during a wildfire event, not just whether it meets minimum code requirements. Factors such as roof assemblies, ember resistance, vent detailing, exterior materials, and site layout all influence underwriting decisions. These principles are central to building science–driven home design and are becoming critical to long-term insurability.
What is the California FAIR Plan and why is it limited?
The California FAIR Plan is an insurer of last resort that provides basic fire coverage when traditional policies are unavailable. While it can be an important safety net, it often caps coverage below full replacement cost and typically requires supplemental policies to approach adequate protection—particularly for high-value homes in wildfire zones.
Why are high-value homes more affected by insurance gaps?
High-value homes often exceed standard policy limits, especially in wildfire-exposed areas. When insurers cap coverage well below actual replacement cost, owners are left with an insurance gap that may only be discovered late in the process. Addressing risk and insurance early—during planning for high-end custom homes and rebuilds helps avoid costly redesigns or uninsured exposure.
Can wildfire insurance affect rebuilding after a fire in California?
Yes. Many homeowners assume rebuilding is straightforward after a fire, but insurance limitations often dictate what can be rebuilt, how quickly, and at what cost. Coverage caps, exclusions, and underwriting conditions frequently require design adjustments or phased construction strategies. This is especially true for rebuilding in Pacific Palisades and other fire-affected areas, where insurance constraints are now a primary planning factor.
When should insurance be addressed during a custom home or rebuild project?
Insurance should be addressed before architectural design is finalized. Early coordination helps ensure design decisions align with underwriting requirements, avoids late-stage redesigns, and reduces the risk of completing a home that cannot be insured adequately. This applies equally to new construction and high-end remodels in wildfire-prone areas.
Do wildfire mitigation strategies reduce insurance costs or improve coverage?
In some cases, yes. While mitigation does not guarantee lower premiums, insurers and specialty underwriters increasingly consider fire-resistant assemblies, site design, and suppression strategies when evaluating coverage limits and eligibility. Performance-based strategies, rather than code minimums, are discussed in greater depth throughout our building science and wildfire resilience blog.
Is the California FAIR Plan enough to fully insure a high-value home?
Often, no. The FAIR Plan is designed as a last-resort option and typically caps coverage below the replacement cost of high-value homes. Supplemental policies may be required, and in some cases, may be difficult or impossible to obtain without additional risk-mitigation measures incorporated into the home’s design.
Final Thought
The Palisades and Altadena fires were not anomalies. They were a stress test—and the insurance system responded by tightening, retreating, and recalibrating.
The homes that will perform best in California over the next decade will not simply be well designed or code-compliant. They will be strategically planned around risk, response, and insurability.
These conversations need to happen early. If you’re planning a project in a wildfire-exposed area, connect with us early in the design process to align performance, resilience, and insurance before constraints become liabilities.
