The basic manner most properties are inbuilt America — the labor-intensive strategy of developing standard wooden framing on website — hasn’t modified a lot for greater than a century, despite the fact that extra industrial strategies and applied sciences have lengthy held the potential to be quicker, cheaper or extra dependable. In Sweden, for example, 90% of single-family properties are prefabricated — total buildings, or giant parts, constructed in a manufacturing facility for effectivity after which assembled rapidly on website, mentioned Ryan E. Smith, director of the College of Structure on the College of Arizona and founding accomplice at Mod X, a prefab development consultancy. In the meantime, prefab development represented simply 3% of single-family properties within the U.S. in 2023, in accordance with the Nationwide Assn. of Homebuilders.
However the devastating Palisades and Eaton fires, mentioned Smith and others, could possibly be a tipping level. The area must rebuild greater than 16,000 buildings — to not point out 1000’s of momentary buildings for individuals to reside 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 of “alternative” or “unconventional” might turn out to be normal, whether or not we’re prepared or not. About 200 of an estimated 2,000 properties destroyed within the 2023 Maui wildfires have already been rebuilt utilizing prefabrication, mentioned 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 mentioned. 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 mentioned she helps prefab as a software 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 mentioned. “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 fireplace zones, giving them a possibility to maneuver into the mainstream. However nearly all acknowledge that prospects nonetheless have lots to study. Many nonetheless confuse prefab with so-called manufactured properties, which are sometimes constructed to decrease requirements of high quality and catastrophe resilience. Quickly altering know-how implies that seemingly unthinkable options, corresponding to 3D-printed homes, are creating extra thrilling decisions — but in addition extra confusion. Listed here are a number of the key methods that would play a task 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 individuals who misplaced their properties within the fires.

Consider it or not, one possibility for rebuilding is 3D-printed development: using large-scale industrial printers to layer constructing supplies like concrete (often on the house website) or composites (often in a manufacturing facility) into partitions and different structural parts. Labor might be less expensive, engineering might be extra exact and development might be quicker. Nevertheless it’s not what most owners are used to, and the novelty can also imply native officers is perhaps slower to problem approvals. Though corporations profiled for this story mentioned they do meet present constructing requirements, L.A. County’s Bodek mentioned she was not conscious of whether or not this type 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 way that founder Gene Eidelman mentioned was extra sustainable and cheaper than concrete. The shells, that are watertight and surprisingly sturdy, often might be accomplished for a undertaking in 24 hours. Staff then set up insulation, cabinetry, electrical, plumbing and extra, often 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 mentioned.

Azure’s manufacturing facility is crammed with modules in course of or not too long ago accomplished, together with ADUs, yard places of work, storage and glamping models, and small properties. One a part of the manufacturing facility has three giant robots printing modules on large rotating trays. Eidelman mentioned Azure had obtained dozens of calls from affected owners within the hearth zones and has constructed greater than 100 models elsewhere, with one other 150 within the pipeline. The corporate’s X sequence of models 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 mentioned. New properties and ADUs begin at $200 to $250 per sq. foot and might be personalized and enlarged by placing models collectively. The corporate can even work with architects and builders to supply 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 influence of latest 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 quite a few reasonably priced housing initiatives 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 properties on website 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 properties within the space, with at the least six extra underneath negotiation, mentioned Joe Chimenti, Emergent’s director of group growth. Chimenti mentioned Emergent’s prices are comparable to traditional development however that 3D printing can shorten the undertaking 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 components.
Container-based development

Joshua Clark, chief government of Ark Container Houses, began his enterprise modifying metal transport containers into livable areas after dropping two properties 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 mentioned.
His 20- or 40-foot container properties, which price $20,000 and $39,000 respectively, are designed to merge the imperviousness of a metal shell (and a welded sheet metallic ground liner) with a country inside made from cypress and Douglas fir partitions and cabinetry. A lot of the properties, which have full utilities, shall be utilized in hearth zones as momentary lodging and will turn out to be everlasting ADUs after foremost homes get constructed.

The containers, that are completed in Louisiana, might be shipped wherever within the nation. A consumer in Malibu resides in a single, Clark mentioned. The models haven’t any home windows aside from a glass door and home windows at one finish of the field, which might 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 mentioned.
He added: “These disasters are not gonna stop. They’re gonna keep coming at us.”
Panelized development
The agency SuperLA makes use of prefabricated parts to create versatile fashionable dwelling designs.
(SuperLA)
A better thought for owners, 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 website and assembling them there.
Native firm SuperLA, which had centered on multifamily housing just like the Bungalows on Marathon flats in Silver Lake earlier than the fires, not too long ago pivoted to single-family prefabs to fulfill the brand new demand. Founder Aaron van Schaik mentioned he already has began website research with two households and is speaking with greater than 10 extra. Working from a set “product” design, SuperLA’s group assembles prefabricated parts to create gentle, ethereal environments which are all electrical (no gasoline home equipment) and surrounded by native landscaping. Van Schaik mentioned he selected panelized development as a result of transport is less complicated and since lenders and insurers have fewer questions, however he mentioned the core profit is definitely design flexibility.
“We are not constrained in a system,” he mentioned. “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 mentioned, not together with auxiliary prices like foundations and utility hookups. Van Schaik mentioned the corporate is modifying its system to incorporate fire-hardening components, and this week SuperLA mentioned its Residence No. 1 has been pre-approved by the Los Angeles County Planning Division, that means purchasers “should be able to get planning approval within a couple of days versus a couple of months,” Van Schaik mentioned.

Due to its design flexibility, panelized prefab is particularly fashionable in high-end customized housing. Turkel Design creates customized properties throughout North America with panelized parts assembled by native builders in a extra conventional method. Turkel’s initiatives sometimes price $1,000 to $2,000 per sq. foot, mentioned Michael Sylvester, the agency’s director of finance and operations. Shoppers aren’t in search of price financial savings however somewhat the “predictability of the quality and the timeline,” mentioned Sylvester, who added that the corporate has fielded curiosity from greater than 40 potential prospects in Pacific Palisades.
Modular development
The corporate Cassette has developed modular properties 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 prospects within the hearth zones.

Essentially 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” parts — rooms that usually 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 might be difficult to move to tight websites corresponding to L.A’s fire-affected canyons.
Samara, a builder of modular properties and ADUs launched by Airbnb co-founder Joe Gebbia, not too long ago partnered with Rick Caruso’s Steadfast LA to construct near 100 properties (price about $15 million) for low- to moderate-income residents affected by the latest fires. However there are various different corporations on this area — some already busy within the hearth zones.
A Samara XL modular home is lowered onto its basis at a undertaking website 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 lift $30 million within the hopes of offering between 80 and 100 Samara XL properties for hearth victims.

Santa Monica-based Plant Prefab builds about two-thirds of its properties, ADUs and multifamily buildings using modular development, in accordance with proprietor Steve Glenn. For the reason that fires, the 9-year-old firm has obtained greater than 250 undertaking inquiries in Pacific Palisades and Altadena, and it has signed contracts with two purchasers.
“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 mentioned. “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 variety of scales and budgets, most of its single-family initiatives price between $225 and $500 per sq. foot, excluding website prices like foundations, utility hookups and allowing. Glenn mentioned Plant Prefab can get its homes up in about half the time of standard 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 parts. Machines reduce 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 website, somewhat 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, metallic roofs, tempered glass and rooftop sprinkler programs, Glenn mentioned. The corporate constructed fire-resistant properties 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, slender 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 models are wrapped in lapped fiber-cement panels and rated for wildfire zones, Kaplan mentioned. They arrive geared up with home windows on either side plus utilities, cabinetry and extra. Base modules vary from $160,000 (40 foot) to $200,000 (60 foot), not together with supply and website prices.
Kaplan mentioned the corporate has signed contracts with two prospects within the hearth zones and is hoping to construct as many as 50 models in these areas inside the 12 months. Though its initiatives nonetheless require development website inspections, its constructing permits have been preapproved by the state’s Housing and Group Improvement workplace, saving quite a lot of time. (It is a large benefit of most modular initiatives, significantly in California, which is proactive about performing approvals at modular factories.)

As a result of Jollies prime out at 870 sq. ft, Kaplan expects most fire-affected purchasers to make use of them first as momentary lodging and ultimately as everlasting ADUs. Shopper Alyson Dutch is doing simply that on a website in Malibu.
“This buys me time,” mentioned Dutch, who remains to be determining learn how to rebuild her dwelling. “Building anywhere is difficult and time-consuming, and if I could have an instant lodging the answer is yes.”
Probably the most refined 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 centered on hearth rebuilding. Its properties, which might 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 mentioned, is serving middle-class residents with properties that run about $250 to $300 per sq. foot, not together with website prices.
