Building Non-Combustible Already Cuts Your Insurance Bill in Half
What that means for buyers, in wildfire zones and out of them
If you are shopping for a home in California, your insurance premium is no longer a footnote in the financial conversation. For many buyers, it has become a deciding factor. Carriers have left the state. The FAIR Plan, California's insurer of last resort, paid out nearly $3.5 billion following the January 2025 fires after handling roughly 5,400 claims, numbers that would have been unthinkable for a program designed as a temporary safety net. Premiums for those who can still get coverage have climbed sharply, and the market shows no sign of stabilizing.
Against that backdrop, here is a data point worth sitting with.
According to Mac Ischanov, CRIS, CIC, CRM, of Acrisure, homes built with non-combustible construction are seeing 40 to 60 percent lower premiums compared to similar wood-frame homes in the same area. Not a modest discount. Not a token credit for a Class A roof. And critically: that differential holds whether the home is in a wildfire zone or not. Because these homes use non-combustible materials with zero fuel load, insurers consider them a materially lower fire risk across the board.
That number deserves more attention than it has gotten.
What the Market Is Already Telling Us
The insurance industry has spent several years arguing that it cannot price risk precisely enough to stay in California. Carriers have cited the difficulty of underwriting individual properties, the limitations of available data, the inadequacy of legacy models. Location, they have said, is the most reliable variable they have.
But a 40 to 60 percent premium differential for non-combustible construction says something different. It says that at least some carriers already know how to distinguish a steel-framed home from a wood-framed one. They already understand that a home built from materials that will not ignite, will not contribute fuel, and will not sustain fire represents a categorically different exposure. And they are pricing it accordingly.
This is not a theoretical argument about what insurers should do. It is a description of what some are already doing.
The Map Problem
There is a second dysfunction in this market that rarely gets named: the government classifications that are supposed to define wildfire risk are themselves unreliable, and insurers know it.
California's fire hazard severity zone maps are updated infrequently. The maps in effect before January 2025 had not been meaningfully refreshed in over a decade. Much of Pasadena and Altadena was not classified as a Very High Fire Hazard Severity Zone before the wildfires burned tens of thousands of structures there. CAL FIRE's updated March 2025 maps have since expanded High and Very High zones in both communities, but only after the damage was done.
This matters because the official classifications drive policy decisions, coverage availability, and in many cases, buyer perception of risk. Carriers have largely known the maps were stale and built proprietary models to compensate. But buyers relying on a state classification to understand their exposure have been working with incomplete information.
The practical result: homeowners who believed they were outside wildfire risk zones were not. And homeowners in communities that are now reclassified are facing a repriced market with little warning.
What Wildfire Zone Premiums Actually Look Like
To put the 40 to 60 percent differential in concrete terms, consider the numbers Ischanov describes.
A typical Bay Area home in a standard location might carry an annual insurance premium of around $2,000. That same home in a high wildfire risk area could easily cost $5,000 or more per year, and often higher. The reason premiums spiral so sharply in fire-prone areas is not just elevated base rates. It is also structural: many major insurers have non-renewed policies in wildfire areas or left the state entirely, pushing homeowners onto the FAIR Plan. But FAIR Plan coverage is not a standalone product. It must be purchased together with supplemental Difference in Conditions coverage, and the combined cost drives premiums well above what a standard policy would have run.
Apply the non-combustible differential to those numbers and the financial case becomes clear. A 40 to 60 percent reduction on a $5,000 annual premium is $2,000 to $3,000 back in a buyer's pocket every year. Over a decade of ownership, that is a significant number, and one that does not show up in most home purchase conversations.
Why Class A Ratings Are Not Enough
Some carriers do offer modest discounts for Class A-rated roofing, which sounds like progress until you understand what Class A actually measures. It is a performance rating under standardized fire exposure testing, not a material composition standard. A treated wood shake, an asphalt shingle, and a steel roof panel can all achieve Class A designation. They perform differently under test conditions, but a treated wood shake is still wood. It will still ignite, still contribute fuel, still burn. A steel roof will not.
Pricing them the same because they share a rating category is a category error, and it is one the industry has been making quietly for years. The principle that construction materials affect risk is already embedded in insurance pricing. Class A discounts prove it. But the industry has stopped at performance ratings when the more fundamental question is simpler: what is this structure made of, and will it burn?
What This Means If You Are Buying or Building
For buyers considering a non-combustible home in a standard risk area, the insurance math is already compelling. A 40 to 60 percent reduction in annual premium is a meaningful number over the life of ownership. It changes the total cost calculation, the monthly carrying cost, and the resale story.
For buyers in or near wildfire zones, the picture is equally important, and perhaps more so. The premium savings are larger in absolute dollar terms. The coverage availability question, which has effectively collapsed to a binary of insurable or uninsurable zip code for many buyers, may look different for a home that insurers already price as a lower fire risk regardless of location. And for anyone rebuilding after a loss, the choice of materials is not just a safety decision. In a market that is beginning to price structure quality, it is a financial one.
California's Sustainable Insurance Strategy, which took effect just days before the January 2025 fires, has opened regulatory space for more precise risk-based pricing. The carriers who figure out how to underwrite non-combustible construction consistently across risk zones will have a competitive advantage. The buyers who build non-combustibly will be the first to benefit.
What We Build, and Why It Matters Here
At Neovi, we build with steel framing, non-combustible Closed Wall panels, metal roofing, and triple-paned windows. Not as an upgrade. As the baseline.
The 40 to 60 percent insurance differential that Ischanov describes is one signal that the market already recognizes what that means. A home with zero fuel load is not the same risk as a wood-framed home, and the carriers who are pricing carefully know it.
A home that will not burn should cost less to insure. In a growing number of cases, it already does.
A Call to the Insurance Industry
The data is there. The tools are there. The regulatory environment is more permissive than it has been in decades.
We are calling on California's insurers, and the broader industry, to make three commitments:
First: Apply material-based underwriting consistently across all risk zones. If non-combustible construction earns a 40 to 60 percent discount in standard risk areas, that logic should apply with even greater force where fire exposure is the primary variable. The differential should be larger in wildfire zones, not absent.
Second: Move beyond performance ratings to material composition. Class A designation is a floor, not a finish line. A treated wood roof and a steel roof are not the same risk. Price the difference.
Third: Build a rebuild incentive that reaches homeowners between loss and reconstruction. That window is when the market has the greatest opportunity to change what gets built, and to reduce its own future exposure in the process.
Forty billion dollars in claims from a single fire season should be enough to change the question. Not just "where is this home?" but "what is it made of?"
California's wildfire problem is not going away. But what we build, and how we price it, can change. The two need to move together.
