Jason and Colleen Warnesky are among dozens of families in Altadena, Calif., who have opted to rebuild with manufactured homes, following the 2025 Eaton Fire. The couple told NPR they were partially motivated go with a prefabricated home by safety concerns. “I think that we both felt early on, if there was a way to make it so that we had less to worry about if another fire happened in the future,” we’d go with that, Colleen Warnesky said.

When the Station Fire roared through the Angeles National Forest in 2009, Colleen and Jason Warnesky could see it from the front porch of their Altadena, Calif., home. Eleven years later, the family witnessed the Bobcat Fire from the same spot as it became one of the largest fires in Los Angeles County history. Their house remained standing after both close calls. So when the Eaton Fire struck more than 3 miles away in January 2025, they were certain they'd again remain unscathed.
"We couldn't imagine how it would get from all the way over there to our house," Colleen Warnesky told NPR, as she pointed to the lush mountains, on a recent Sunday afternoon.
Fifteen months later the couple is pacing around the fenced-in dirt lot that was once the site of their 1,400 sq. foot home. So far the land has been cleared of all toxins, and they're waiting on the city to approve drainage permits before construction workers can start pouring the foundation
The Warneskys are among the dozens of families in the immediate neighborhood who have opted to rebuild with manufactured homes. They were swayed by a local program launched by city-LAB UCLA, a center founded by the University of California, Los Angeles' Architecture and Urban Design Department, that included a showcase of six prefab housing options and as well as a guide to help navigate the process and secure financing.

The spate of wildfires, hurricanes, tornadoes and floods fueled by manmade climate change that have plagued vast swaths of the country in recent years, are changing the housing industry. That's because people like the Warneskys, who are seeking to rebuild in disaster-prone regions, are searching for greater peace of mind. As a result, they're turning away from stick-builds and embracing prefabricated homes that are made using materials that are fire resistant and can withstand extreme weather that are now considered standard, and are often more affordable.
Manufacturers are meeting that demand with innovative and safer alternatives. Many companies are designing prefab houses that can withstand category 5 hurricane winds – up to 250 mph – earthquakes, hail storms, massive snowfall and fire. Depending on customizable preferences, prices can vary from below $100 per square foot to over $500 per square foot, excluding land. But even those prices often fall under traditional on-site building costs in many parts of the country.
"We're working with Honomobo, which is one modular company out of Canada. And then the people across the way are working with another company called Bevy House. And then there's a whole set of three families on Harriet that are working with a third modular company," Warnesky said, pointing out various vacant or half-built lots in the neighborhood.
"It was a combination of factors," Warnesky said, explaining why they have opted to forgo a traditional build. After losing everything, and the stress of dealing with the seemingly endless insurance paperwork, they had decision fatigue. The idea of picking something out of a catalogue that would arrive fully built seemed like a lifesaver.
"But a big part of it was also safety," Warnesky clarified. She added, "I think that we both felt early on, if there was a way to make it so that we had less to worry about if another fire happened in the future," we'd go with that.
For their own house, which will largely consist of glass, steel and concrete, the Warneskys said they bought a package that is specifically designed for a wildland urban interface environment, known as WUI. These are areas where real estate developments and infrastructure, butt up against wildland vegetation.
Jason Warnesky described some of the features of the old, post WWII-built home. It was modest but comfortable. It had a redwood deck that spanned a big section of the backyard, he said.
"I would suspect that was probably one of the first things that went up on our house," he said.
"We won't do that again," his wife added.
The building prefab business
The Manufactured Housing Institute reports that as of 2024 nearly 21 million people in the U.S. live in a manufactured or mobile home. And, manufactured homes made up more than 9% of new home starts in the same year. Meanwhile, consumer prices have remained largely unchanged over the past three years, making them increasingly attractive to first time buyers.
The same study noted that there are three U.S.-based companies that account for about 83% of the nation's market share. Most of those sales are happening in states with nearly annual flooding, hurricane or wildfire disasters — Texas, Florida and California.
Given the escalating climate risks across the country, Harrison Langley, CEO of MDLR Brands, believes that traditional on-site building is unsustainable. His company has built single family prefabricated homes, apartment buildings and commercial structures in the Bahamas, following 2019's Hurricane Dorian, California, Tennessee and North Carolina.
"The building materials space is run by dinosaurs," he told NPR. "The way we've been building for the last 100 years really hasn't changed. But the materials have gotten less strong. A two-by-four is no longer two-by-four. It's smaller."
The company offers manufactured kit homes as well as custom designed projects that are built using composite structural insulated panels. Each one has a 30-minute fire rating, meaning "you could hide behind this wall without the heat coming through for 30 minutes," he explained, adding that the panels can be hardened even further by using a cement board on top of the panels. "That could give you about an hour to get out of a building," Langley added.
Another bonus is that the panels are also more elastic than a wooden frame, making the houses better capable of withstanding earthquakes. And, he said, because the panels have an exterior fiberglass layer, they can stand up to category 5 hurricane winds. (Third party certifiers test it by shooting a two-by-four traveling at 170 mph, Langley explained.)
According to Langley, America has been on the cusp of embracing modular and prefabricated homes for some time. But, he believes, the growing ubiquity of accessory dwelling units is serving as "proof of concept" for potential clients. "People are used to seeing them now," he said.
Beyond a boxy modular style

For some people, the reluctance to embrace a modular or manufactured build, has less to do with costs, and more to do with style. Or a perceived absence of it.
Across the street from Colleen and Jason Warnesky are Linda and Liam Mennis. They also lost their 1940s 1,600 sq. ft. home in the Eaton Fire. Initially they were thinking of going with a traditional stick-build home but after a discussion with their architect, they learned they could design a customized manufactured home.
"We couldn't do a cookie-cutter house," Mennis told NPR. "We didn't want to pick something from a catalogue that would look exactly like somebody else's house."
They're now working with Bevy House, whose tag line is, "The conventional home building process is broken. We're the solution." Instead of boxy structures, they take personalized architectural plans and figure out how to make them modular so they can be fabricated at their facilities and put together on site. A majority of the company's builds are installed in California, and they've worked with several fire victims. Following the destructive 2018 Woolsey Fire in Ventura and Los Angeles counties, they built one of the first homes to receive occupancy post-fire, according to their website. It's a Spanish revival, 5 bedroom, 7 bathroom, nearly 8,000 square foot spread, that features custom reclaimed beams. The project was a partial rebuild, as a large portion of the original home was lost in the fire.
For Mennis and his wife, it was a streamlined process. After finalizing a design plan, he said, Bevy House "makes sure they can break it up into modules" in a 3-D rendering system, and they get started on production.

Prefab's past
The idea of creating aesthetically pleasing and affordable modular homes on a mass scale is not a new one. Seventy-seven years ago famed architects and furniture designers Ray and Charles Eames, came up with a modernist blueprint for a system composed of inexpensive and off-the-shelf materials from industrial and commercial catalogues that could be easily assembled. Their own iconic home and studio space, Case Study No. 8 house, served as a model of what could be done.
Eames Demetrios, director of the Eames Office and chairman of the Eames Foundation, has revived his grandparents' dream. Together with Spanish office furniture brand Kettal, Eames Office rolled out the Eames Pavilion system last week at the Triennale di Milano exhibition in Italy. It is a modular, pre-fabricated kit that uses aluminum frames with interchangeable glass, wood, and composite panels. The initial product is only for a single room that can serve as an office or studio space. But by 2027, Demetrios said, it will expand to allow for customizable configurations of single or multi-level dwellings.
"What is wonderful about it is it isn't a copy of the Eames House," Demetrios told NPR. "It's not a facsimile. But it certainly has the spirit of it. And when you look closely, you realize that it's something that is different, which is really trying to create a system out of it."
The kits will be on the pricier side of prefabricated homes, but Demetrios said they intend to keep costs below $500 per square foot. Clients will also have options to swap out materials that may suit the building site better, he added. Because it is a modular system, Demetrios explained, "as innovations happen it is possible to include those in a more dynamic way."
He added: "I'm predicting in about five years we'll have houses that people will almost not be able to tell are from the same system. And I think that that's part of the power of it. And that's part of the opportunity of it."
