The basic method most houses are in-built America — the labor-intensive technique of setting up typical wooden framing on web site — hasn’t modified a lot for greater than a century, regardless that extra industrial strategies and applied sciences have lengthy held the potential to be sooner, cheaper or extra dependable. In Sweden, as an example, 90% of single-family houses are prefabricated — total buildings, or massive parts, constructed in a manufacturing facility for effectivity after which assembled rapidly on web site, stated Ryan E. Smith, director of the Faculty of Structure on the College of Arizona and founding companion at Mod X, a prefab development consultancy. In the meantime, prefab development represented simply 3% of single-family houses within the U.S. in 2023, based on the Nationwide Assn. of Homebuilders.
However the devastating Palisades and Eaton fires, stated Smith and others, may very well be a tipping level. The area must rebuild greater than 16,000 buildings — to not point out hundreds of momentary buildings for individuals to stay in earlier than then — in a market already weighed down by bureaucratic hurdles, restricted labor and excessive supplies prices. What was as soon as thought-about “alternative” or “unconventional” might turn out to be customary, whether or not we’re prepared or not. About 200 of an estimated 2,000 houses destroyed within the 2023 Maui wildfires have already been rebuilt utilizing prefabrication, stated Tom Hardiman, government director of the Modular Constructing Institute, a nonprofit commerce affiliation.
“When the pain of changing is less than the pain of staying the same, then people start looking into doing something different,” Smith stated. Though he identified a number of the reason why prefab has but to take off, he sees change as inevitable, not solely due to the fires but in addition as a result of nation’s housing scarcity and affordability disaster. “I’m 49 and have 20-something kids. They’ve told me point-blank, ‘I’m not going to be able to buy a house where I live.’”
L.A. County Planning Director Amy Bodek stated she helps prefab as a device to assist residents rebuild rapidly, and she or he hopes to ease allowing. “We’re trying to stabilize a large segment of our population that has been affected by this disaster,” she stated. “The faster we can get folks into their own version of shelter, the better we can make sure that the economy is going to be stable and hopefully rebound.”
Prefab development corporations are seeing a deluge of requests from the hearth zones, giving them a possibility to maneuver into the mainstream. However nearly all acknowledge that clients nonetheless have loads to study. Many nonetheless confuse prefab with so-called manufactured houses, which are sometimes constructed to decrease requirements of high quality and catastrophe resilience. Quickly altering know-how signifies that seemingly unthinkable alternate options, akin to 3D-printed homes, are creating extra thrilling decisions — but in addition extra confusion. Listed below are among the key strategies that would play a job in rebuilding L.A. — and fixing our housing disaster — within the coming years.
3D-printed development
Azure creates 3D-printed modules with a composite combination of fiberglass and recycled plastic bottles. The corporate’s X sequence has been authorised to be used as momentary housing for many who misplaced their houses within the fires.

Consider it or not, one choice for rebuilding is 3D-printed development: using large-scale industrial printers to layer constructing supplies like concrete (normally on the house web site) or composites (normally in a manufacturing facility) into partitions and different structural elements. Labor will be less expensive, engineering will be extra exact and development will be sooner. Nevertheless it’s not what most householders are used to, and the novelty can also imply native officers is likely to be slower to challenge approvals. Though corporations profiled for this story stated they do meet present constructing requirements, L.A. County’s Bodek stated she was not conscious of whether or not this sort of development met seismic or hearth codes.
At its Gardena manufacturing facility, L.A.-based Azure creates modules with a composite combination of fiberglass and recycled plastic bottles, a technique that founder Gene Eidelman stated was extra sustainable and cheaper than concrete. The shells, that are watertight and surprisingly sturdy, normally will be accomplished for a mission in 24 hours. Employees then set up insulation, cabinetry, electrical, plumbing and extra, normally in about 12 to fifteen days. For hearth zones, the corporate is including fire-rated panels to its modules’ exteriors whereas it really works to make the composite method itself extra hearth resistant, Eidelman stated.

Azure’s manufacturing facility is stuffed with modules in course of or just lately accomplished, together with ADUs, yard places of work, storage and glamping items, and small houses. One a part of the manufacturing facility has three massive robots printing modules on huge rotating trays. Eidelman stated Azure had obtained dozens of calls from affected householders within the hearth zones and has constructed greater than 100 items elsewhere, with one other 150 within the pipeline. The corporate’s X sequence of items on wheels, which ranges from $49,900 to $96,900, has been marketed to individuals who need to camp or in any other case get away. It’s additionally authorised within the metropolis of L.A. as momentary lodging for hearth survivors, Eidelman stated. New houses and ADUs begin at $200 to $250 per sq. foot and will be personalized and enlarged by placing items collectively. The corporate also can work with architects and builders to offer prefabricated panels.
“This has to happen. There is just not enough capacity to rebuild,” famous Eidelman, pointing to a longstanding dearth of labor and supplies within the area, which has turn out to be exacerbated by the spiked demand from the fires, to not point out the affect of current tariffs.

Emergent, a 3D-printed housing firm primarily based in Redding, Calif., was conceived largely as a response to the 2018 Carr hearth, and by 2022 it had constructed various inexpensive housing tasks in Shasta County. The corporate additionally collaborated with structure college students at Woodbury College in Burbank to construct its 2023 entry for the U.S. Division of Power’s Photo voltaic Decathlon competitors. The agency prints houses on web site utilizing Portland cement, which is resilient, moldable and acquainted to allowing officers. Emergent’s founder, Don Ajamian, is initially from Altadena, and the corporate has signed contracts to construct 4 houses within the space, with at the least six extra below negotiation, stated Joe Chimenti, Emergent’s director of neighborhood growth. Chimenti stated Emergent’s prices are comparable to traditional development however that 3D printing can shorten the mission timeline by 10% to twenty%. In partnership with architects like Benjamin Albertson and Rad Studio, the robotic gantry system can produce extra free-form designs than conventional development, with tight curves, circles and different parts.
Container-based development

Joshua Clark, chief government of Ark Container Properties, began his enterprise modifying metal transport containers into livable areas after dropping two houses to pure disasters — a landslide in Malibu and a hurricane in Louisiana.
“I want something that lasts centuries. I got sick of seeing people lose it all,” Clark stated.
His 20- or 40-foot container houses, which value $20,000 and $39,000 respectively, are designed to merge the imperviousness of a metal shell (and a welded sheet steel flooring liner) with a country inside product of cypress and Douglas fir partitions and cabinetry. Many of the houses, which have full utilities, will probably be utilized in hearth zones as momentary lodging and will turn out to be everlasting ADUs after primary homes get constructed.

The containers, that are completed in Louisiana, will be shipped wherever within the nation. A shopper in Malibu resides in a single, Clark stated. The items don’t have any home windows aside from a glass door and home windows at one finish of the field, which will be sealed up by way of the metal container door. “As soon as you carve into a cargo container, you compromise the structural integrity,” Clark stated.
He added: “These disasters are not gonna stop. They’re gonna keep coming at us.”
Panelized development
The agency SuperLA makes use of prefabricated elements to create versatile fashionable house designs.

A neater concept for householders, builders and code-enforcement officers to digest is panelized development, which consists of fabricating partitions, flooring and roof panels in a manufacturing facility, transport them to a house web site and assembling them there.
Native firm SuperLA, which had targeted on multifamily housing just like the Bungalows on Marathon flats in Silver Lake earlier than the fires, just lately pivoted to single-family prefabs to fulfill the brand new demand. Founder Aaron van Schaik stated he already has began web site research with two households and is speaking with greater than 10 extra. Working from a set “product” design, SuperLA’s group assembles prefabricated elements to create mild, ethereal environments which might be all electrical (no gasoline home equipment) and surrounded by native landscaping. Van Schaik stated he selected panelized development as a result of transport is less complicated and since lenders and insurers have fewer questions, however he stated the core profit is definitely design flexibility.
“We are not constrained in a system,” he stated. “This allows us to focus on the occupants’ experience as the first priority.”
The price of a three-bedroom, 1,750-square-foot house is barely greater than $500 per sq. foot, the corporate stated, not together with auxiliary prices like foundations and utility hookups. Van Schaik stated the corporate is modifying its system to incorporate fire-hardening parts, and this week SuperLA stated its House No. 1 has been pre-approved by the Los Angeles County Planning Division, that means shoppers “should be able to get planning approval within a couple of days versus a couple of months,” Van Schaik stated.

Due to its design flexibility, panelized prefab is very fashionable in high-end customized housing. Turkel Design creates customized houses throughout North America with panelized elements assembled by native builders in a extra conventional method. Turkel’s tasks usually value $1,000 to $2,000 per sq. foot, stated Michael Sylvester, the agency’s director of finance and operations. Purchasers aren’t searching for value financial savings however reasonably the “predictability of the quality and the timeline,” stated Sylvester, who added that the corporate has fielded curiosity from greater than 40 potential clients in Pacific Palisades.
Modular development
The corporate Cassette has developed modular houses known as Jollies, designed by Oonagh Ryan Architects, that are wrapped in fiber-cement panels and rated for wildfire zones. The corporate says it has signed contracts with two clients within the hearth zones.

Probably the most economical — and fashionable — prefab system stays modular development, during which three-dimensional sections of a house are constructed in a manufacturing facility. These “volumetric” elements — rooms that always embody built-in electrical, plumbing and cabinetry — are then transported to the location and assembled like constructing blocks utilizing cranes. Modular development is quicker and simpler to get permitted than panelized development, however it’s more durable to customise. It additionally will be difficult to move to tight websites akin to L.A’s fire-affected canyons.
Samara, a builder of modular houses and ADUs launched by Airbnb co-founder Joe Gebbia, just lately partnered with Rick Caruso’s Steadfast LA to construct near 100 houses (value about $15 million) for low- to moderate-income residents affected by the current fires. However there are a lot of different corporations on this area — some already busy within the hearth zones.
A Samara XL modular home is lowered onto its basis at a mission web site in Culver Metropolis . Connections for water, electrical energy and sewage are already in place. Developer and former mayoral candidate Rick Caruso’s Steadfast LA nonprofit desires to boost $30 million within the hopes of offering between 80 and 100 Samara XL houses for hearth victims.

Santa Monica-based Plant Prefab builds about two-thirds of its houses, ADUs and multifamily buildings using modular development, based on proprietor Steve Glenn. For the reason that fires, the 9-year-old firm has obtained greater than 250 mission inquiries in Pacific Palisades and Altadena, and it has signed contracts with two shoppers.
“You’ve got thousands of people, the vast majority of which had not planned to build a home, who are suddenly thrust into the position of building one for the first time,” Glenn stated. “When people start to do their due diligence, they start to hear about construction delays, cost overruns and quality issues, and often prefab can help address these issues.”
His firm collaborates with architects throughout the nation to create designs, and though it builds at a spread of scales and budgets, most of its single-family tasks value between $225 and $500 per sq. foot, excluding web site prices like foundations, utility hookups and allowing. Glenn stated Plant Prefab can get its homes up in about half the time of typical development.
A couple of 12 months in the past the corporate constructed a 270,000-square-foot automated manufacturing facility in Tejon Ranch, the place it churns out full modules and panelized elements. Machines minimize lumber and route utility pathways; nail weapons join joists, studs and climate wrap; different machines blow in insulation, all guided by a digital mannequin. Whereas that is occurring, contractors can begin doing prep work on web site, reasonably than being slowed down by the extra linear development of conventional development.

For hearth zones, the corporate can tailor its designs to incorporate cementitious cladding, steel roofs, tempered glass and rooftop sprinkler techniques, Glenn stated. The corporate constructed fire-resistant houses after the Woolsey hearth in Malibu and the Tubbs hearth in Northern California.
“It’s a bit of a crisis-tunity,” famous Dafna Kaplan, chief government of Cassette Methods, a modular homebuilding firm she based in 2020. Initially she deliberate to create stackable multifamily buildings, however she pivoted to single-family housing and ADUs in 2024.
Cassette’s modular merchandise, which they name Jollies, are lengthy, slim buildings starting from 40-foot-long one-bedroom/one-baths to 60-foot-long, two-bedroom/two-baths. Designed by L.A.-based Oonagh Ryan Architects and constructed by a number of California-based producers, the items are wrapped in lapped fiber-cement panels and rated for wildfire zones, Kaplan stated. They arrive outfitted with home windows on each side plus utilities, cabinetry and extra. Base modules vary from $160,000 (40 foot) to $200,000 (60 foot), not together with supply and web site prices.
Kaplan stated the corporate has signed contracts with two clients within the hearth zones and is hoping to construct as many as 50 items in these areas throughout the 12 months. Though its tasks nonetheless require development web site inspections, its constructing permits have been preapproved by the state’s Housing and Neighborhood Growth workplace, saving lots of time. (This can be a big benefit of most modular tasks, notably in California, which is proactive about performing approvals at modular factories.)

As a result of Jollies prime out at 870 sq. toes, Kaplan expects most fire-affected shoppers to make use of them first as momentary lodging and finally as everlasting ADUs. Shopper Alyson Dutch is doing simply that on a web site in Malibu.
“This buys me time,” stated Dutch, who continues to be determining how you can rebuild her house. “Building anywhere is difficult and time-consuming, and if I could have an instant lodging the answer is yes.”
Some of the subtle modular corporations round is Dvele, which has produced 275 modules within the U.S. and Canada. The corporate is planning to construct a manufacturing facility in Southern California targeted on hearth rebuilding. Its houses, which will be personalized by combining various-sized modules, vary from one to 4 bedrooms and are solar-powered, constructed to maximise thermal effectivity and indoor air high quality. The corporate, founder Kurt Goodjohn stated, is serving middle-class residents with houses that run about $250 to $300 per sq. foot, not together with web site prices.
