Yes, $200,000 fire insurance premiums are possible in Los Angeles now.

Most of the time, the hot, wealthy, coutured-up real estate agents on the hit Netflix series Selling Sunset make selling luxury homes in the Los Angeles hills look like a breeze. The only adversity the Oppenheim Group girls seem to face is inter-office drama over perceived slights, blown out of proportion by savage gossip and likely invented for the cameras.
But in the new season that premiered last week, one of the agents pulled back the veil, just for a moment, on a problem that’s starting to give their high net worth buyers pause: fire insurance.
In the first episode, agent Emma Hernan throws an open house for brokers at a palatial, $19 million home in Beverly Hills. The modern, 5-bed, 9-bath, has “unobstructed jetliner views from every room,” a “fingerprint-secured Mezcal/Wine tasting room,” an infinity pool, a Himalayan salt sauna, a Japanese soaking tub, a wet steam room, a poolside cabana, a 20-person theater with a bar, and a tacky-as-hell human-sized chess set.

But the house, with its opulent amenities and epic vistas, is tucked into a private hillside surrounded by trees. “When you buy a property in this area, the fire insurance and things along those lines can be pricey,” Hernan tells a group of agents gathered on the balcony.
It turns out, Hernan is throwing the event because the original buyer she lined up fell out of escrow after finding out the fire insurance on the house was going to cost an eye-popping $200,000 per year, minimum.
As she tells the other agents the number “isn’t that crazy for a house in the Hills,” they nod knowingly. “But they expected it to be like $40,000, which isn’t going to happen.”

It’s a wild example of what’s going on in the California insurance market right now, where many homeowners are seeing their rates skyrocket, if not getting dropped from their plans altogether, while others can’t find anyone willing to sell them a policy to begin with — no matter how much they are willing to spend.
“There's some people that cannot get it,” Shelton Wilder, a luxury real estate agent in Los Angeles, told me. “And they checked everywhere and so they just don't have insurance on their home.”
This is a pretty recent phenomenon. A 2021 report by the University of California, Berkeley, Center for Community Innovation traces how fire insurance payouts rose dramatically in the last decade due to continued development in high-risk areas and climate change driving more severe burns. It notes that in the latter half of last century, the industry paid an average of $100 million per year in fire insurance claims in the state. But between 2011 and 2018, that number exploded to an average of $4 billion per year. During the particularly bad wildfire seasons of 2017 and 2018, companies paid out two times in incurred losses what they made in earned premiums.
The following year, there was a 31 percent jump in policy non-renewals statewide, mainly in areas with high wildfire risk, according to the California Department of Insurance. Insurers began retreating from some parts of the state altogether. Last week, State Farm, the largest provider of home insurance policies in the country, put a freeze on new applications in the entire state of California.
“It used to be a negligible part of the home purchase process,” another L.A. real estate agent, Brock Harris, told me. “You would just call State Farm and get a policy and whatever, they all kind of cost the same. In a lot of areas it’s suddenly a big part of the analysis of whether the home is affordable. It's kind of crazy.”
Brock’s wife and partner, Lori Harris, had a similar experience to Hernan, the Netflix star. Her client put an offer on a house in Mandeville Canyon, a ritzy hillside neighborhood where Gweneth Paltrow, Dr. Dre, and Lachlan Murdoch have all bought homes. But then she found out the fire insurance was going to be $100,000. “Obviously it was a huge deterrent,” said Harris. “It spooked her. We have clients who won’t look at Mandeville because of the history of evacuations. There’s only one road down so they get freaked out by it.”
It’s not just higher fire risk that’s driving up premiums. Supply chain issues, labor shortages, and inflation are all making the rebuild process a lot more costly.
Many Golden State residents who can’t find insurance on the market are eligible for coverage through a state-mandated program called the California FAIR Plan, but the premiums are on average much higher. The average market insurance in Los Angeles goes for about $1,500 per year, but the FAIR Plan costs an average of $3,200. (FAIR Plan policies only cover up to $3 million.)
Last year, in an attempt to increase access to coverage, the California Department of Insurance issued first-in-the-nation rules requiring insurers to give discounts to property owners that reduce their wildfire risk, like installing a fire-resistant roof or clearing debris around the structure.
As for the house in Beverly Hills? One year later, it’s still on the market. But it got a $6 million price cut — or the equivalent of those fire insurance payments over the course of a 30-year mortgage.

The spinoff of Lawrence Livermore National Lab has a new 10-point plan to get onto the grid by the 2030s.
One of fusion energy’s newest startups, Inertia Enterprises, is betting that the fastest route to commercial fusion runs through one of the field’s oldest ideas. The company, which raised a $450 million Series A earlier this year, plans to build a power plant based on the laser-driven fusion system pioneered at Lawrence Livermore National Laboratory’s — the only tech yet to have produced more energy from a fusion reaction than it took to initiate it. Now, Inertia has shared its commercialization roadmap exclusively with Heatmap, detailing the 10 near-term capabilities it must demonstrate before this landmark experiment can become a grid-scale power plant by the mid-2030s.
The roadmap offers a route from the national lab’s impressive but commercially impractical fusion demonstrations to an economical power plant capable of producing electricity for the grid. At its core are a set of milestones — mostly aimed at developing cheap, mass-manufacturable components — that Inertia says it must clear before those individual systems can be integrated into a working plant. This road is not necessarily linear, however, as various teams will likely be working on many of these goals simultaneously.
At least the physics of Inertia’s approach are already proven, the startup’s CEO Jeff Lawson told me, pointing to the fusion experiments at Lawrence Livermore’s National Ignition Facility as a proof-of-concept. The lab’s demonstration of net energy gain caps more than six decades and $30 billion (in 2026 dollars) of U.S. fusion research. The remaining challenges, he argued, are all engineering-related, requiring “elbow grease, hard work, and smart people” rather than breakthroughs in fusion science.
"It seems to us like a startup or a commercial company of any variety should be focused on commercializing a proven scientific result, as opposed to actually trying to demonstrate the basic science to begin with," Lawson told me. Basic science, he argues, is better left to national labs and universities, where researchers can pursue "unbounded problems" that don’t align with the expectations and timelines of venture-backed startups.
Indeed, no fusion startup has yet achieved scientific breakeven, the milestone Lawrence Livermore first hit in 2022, and has since repeated numerous times. But leading players such as Commonwealth Fusion Systems and Helion Energy maintain that it’s only a matter of time before they validate the physics behind their own reactor designs, which they claim will be highly cost-competitive.
Lawson, on the other hand, readily acknowledged that Lawrence Livermore’s tech is uneconomical in its current form. His bet is simply that the more predictable path to a commercial reactor is to drive down the cost of the lab’s validated fusion approach, known as inertial confinement. This system relies on high-powered lasers firing at a millimeter-scale pellet of fusion fuel, compressing it to extreme temperatures and pressures until the atoms fuse. Today, the National Ignition Facility makes each individual fusion target by hand, a workable solution given that it only uses about a dozen per year.
That production model, however, isn’t remotely plausible for a grid-scale power plant. Because each fusion reaction lasts just a fraction of a billionth of a second, a commercial facility must fire its lasers at a fresh target about 10 times per second to generate continuous electricity — requiring the production of hundreds of millions of targets each year.
Scaling production to roughly a million pellets per day and making them inexpensive enough for commercial operation without compromising the strength or precision required for fusion ignition is central to Inertia’s roadmap. That includes goals five, seven, eight and nine — industrializing the manufacturing of the carbon shells that hold the fusion fuel, making the thin films that hold those carbon shells both durable and cheap, scaling up and automating fusion target assembly, and speeding up how fast targets are filled with the requisite deuterium-tritium fuel.
The other central focus of the roadmap is the laser system, which will ultimately consist of 1,000 individual units operating in concert to compress and heat the fusion fuel. Key priorities include reducing the system’s cost (goal two), dramatically increasing its firing cadence (goal three), and bolstering its durability to withstand high-intensity operations (goal four). Goal six also complements these efforts, calling for the development of a control system capable of tracking moving fusion targets to precisely align each laser shot.
Goals one and 10 bookend the journey with some broader milestones. The first focuses on increasing the fusion target’s energy gain — the ratio of fusion energy produced to laser energy delivered — to more than 25 times ignition. Today, the National Ignition Facility’s best-performing laser shot has yielded a gain of just over four times what it took to start the reaction. Goal 10 then zooms out to the ultimate objective: integrating all these technologies into a commercially viable power plant that can deliver either electricity or industrial heat to end customers.
To reach that point, Inertia has embarked on an industrial engineering hiring spree, recruiting folks with experience taking complex hardware systems from prototype to mass production, “not unlike the processes that are used in the semiconductor or consumer electronics world,” Lawson explained. The company has been making progress on its component development goals since the beginning of the year, he told me, and expects to announce the successful demonstration of a few of these milestones in the coming months. Lawson ultimately expects Inertia to complete the core components of its laser and target manufacturing systems by the middle of next year.
The team will spend the next two to three years integrating these individual pieces into two fully operational subsystems, a prototype laser system and a target manufacturing line. Around 2030, the company will begin combining those subsystems into a first-of-a-kind fusion power plant, which will also serve as the proving ground for the target chamber, tritium fuel breeding system, and power conversion system that turns fusion heat into electricity. By the middle of the next decade, Inertia aims to be generating power from this first plant, setting the stage for the company to build and connect additional grid-scale commercial power plants.
There are plenty of engineering trade-offs that the company will have to solve for. Take the decision around how to size the target chamber, for example. “If you make it bigger, your walls have an easier time and survive longer, but it’s more expensive. If you make it smaller, your walls have a tougher time because they’re closer to all the heat and energy that the fusion reaction is creating, but now your power plant costs less to build.”
But to Lawson, this represents exactly the type of problem Inertia was built to solve: complex engineering issues that come to the fore once scientists have demonstrated the fundamental physics are sound. He thinks other fusion companies may someday reach this stage, as well — though he’s unwilling to hazard a guess on exactly what approach or startup is best positioned to do so.
“There have been generations of scientists who’ve made their predictions about fusion energy and gotten it wrong,” he told me. “I’m not going to pretend to be smarter than them. All I’m here to say is, just knowing that one did work, we can commercialize it.”
