The Weekly: Unaffordable Housing—A Hidden Driver of Wildfire Risk?
The housing affordability crisis and the wildfire crisis aren't distinct challenges. They're a self-reinforcing cycle that requires investing in resilience to break.
The housing affordability crisis and the wildfire crisis aren't distinct challenges. They're a self-reinforcing cycle that requires investing in resilience to break.
Rising disaster costs drive up insurance premiums, and rising premiums then make housing less affordable. But the feedback loop actually runs in both directions. Unaffordable housing is amplifying the conditions that exacerbate disasters—sending more families into fire-prone areas, adding ignition sources, and raising the stakes of every fire season.
A recent Bloomberg editorial pointed out that homeowners insurance premiums rose nearly 25% on average from 2019 to 2024, contributing to rising rents nationwide. The piece points to more extreme disasters, rising construction costs, and chronic underinvestment in resilience as the driving forces behind spiking insurance premiums.
There is another dynamic at play here as well: As housing costs rise, disaster-vulnerable areas often become the last remaining affordable option. This accelerates the feedback loop between affordability and risk. More people move into harm’s way, which makes disasters more expensive, which drives up insurance costs, which makes housing less affordable. And the cycle perpetuates.
Growth Is Concentrating Where Risk Is Highest
When urban housing becomes unaffordable, families move outward to chase lower prices. That migration increasingly pushes them into the wildland-urban interface (WUI): zones where homes meet flammable landscapes. The WUI has been expanding rapidly across the American West for years, with housing growth in these fire-prone areas outpacing growth in safer locations. In California, where median single-family home prices exceed $900,000, people who are priced out of fire-safe areas are building in fire country.
This expansion changes the risk equation. More homes in the WUI means more ignition sources, more structures to defend, and higher suppression costs. When wildfires inevitably occur, the damage is even more catastrophic. The 2025 Los Angeles fires caused somewhere between $76-131 billion in total property and capital losses, much of it in WUI developments that expanded over the last two decades.
Each megafire event reverberates through insurance markets as carriers reassess their exposure. Premium increases spread out across entire regions, not just the immediate burn zones. A homeowner in suburban Sacramento can see their insurance costs spike because of fires in Shasta County. A renter in San Diego might face higher costs because their landlord's policy doubled.
Then, higher insurance premiums compound the original affordability problem, pushing the next wave of households further into the WUI. The cycle reinforces itself: As households are pushed into higher-risk areas, risk grows, premiums rise, and higher costs push even more families out.
Resilience Is Affordable Housing Policy
Many of the solutions the Bloomberg editorial proposes point in the right direction: prioritizing resilience and creating tax breaks and grants for hardening homes against fire. As they write, these are "short-term expenses with long-term benefits.” A U.S. Chamber of Commerce study found that communities lose as much as $33 in future economic activity for every $1 not invested in disaster resilience. This is especially true in WUI communities, where the return on resilience investment is highest, and where the alternative is another catastrophic fire season absorbed by insurance markets.
And resilience within the WUI is achievable. Research shows that home spacing and building standards are decisive factors in whether structures survive a wildfire. A 2022 study found that California homes built after 2008 and subject to wildfire building codes were 40% less likely to be destroyed in a wildfire compared to those built before 1990, a difference attributed largely to stricter building codes. With resilient building certifications like IBHS Wildlife Prepared Home Plus that go beyond minimum building codes, those survival numbers can be pushed even higher. Smarter design and stronger standards can reduce losses and slow the cycle of rising exposure and rising costs.
The housing affordability crisis and the wildfire insurance crisis are two sides of the same coin. The solution requires resilience: building smarter in the places people are already moving to, and making it more realistic to stay in the places they can't afford to leave.
