America is brief 4.03 million houses—and pioneers of the factory-built residence development enterprise are hopeful {that a} spate of new legislation adjustments might assist flip the tide.
However the development of those houses is not the one hurdle they face.
The primary begins on the very definition of factory-built houses. This kind of housing—additionally referred to as pre-fab or modular housing—is distinctly completely different from cell houses similar to double-wide trailers. But, all of them share the identical definition beneath many state and native housing legal guidelines: manufactured housing.
And that results in the second hurdle: Lumping these definitions collectively means they’ll additionally share the identical stigma, explains Realtor.com® senior economist Joel Berner.
“The key problem is that huge gamers are manufacturing each HUD-regulated double-wides and domestically regulated modular houses, and no business or authorities our bodies are doing a superb job of separating the 2,” says Berner. “A part of a coverage revamp needs to be higher information classification and assortment.”
Both method, manufactured housing, as outlined by the U.S. Division of Housing and City Growth, stays a comparatively area of interest side of the homebuilding business.
HUD recorded 112,800 manufactured residence shipments in 2022, 89,000 in 2023, 103,300 in 2024, and 102,700 in 2025. Every year, it accounts for between 5.9% and seven% of the whole housing begins.
January of this 12 months marked a 16.4% decline in manufactured housing shipments, to 7,400 houses.
And the nation misplaced 5 factories dedicated to housing, falling to 143 in 2025, the Lincoln Institute of Land Coverage stated in its annual report on the enterprise.
Kim Vermeer, president of consulting agency City Habitat Initiatives Inc., which authored the examine, blamed business consolidation. Clayton, Skyline Champion Corp., and Cavco Industries Inc. management 73% of factories.
Extra states, particularly underserved areas, have to do extra to incentivize these factories, Vermeer stated.
Manufacturing facility-built housing is a viable various
In concept, factory-built housing might clear up many issues directly: lowering cycle time and stopping supplies from being wasted within the constructing course of. It might additionally enable for year-round productiveness in elements of the nation the place climate limits constructing time.
What’s extra, homebuilders haven’t got capital tied up in ongoing initiatives in the identical method, which might enable for extra constructing.
Various kinds of manufacturing go well with a number of housing varieties. Properties that may be constructed totally in a manufacturing unit and delivered on a truck go well with reasonably priced housing. Module development fits multifamily initiatives, permitting house items to be inbuilt a manufacturing unit and lowered into the constructing by crane.
Extra widespread within the U.S., although, are panels, partitions, and trusses that may be inbuilt a manufacturing unit and lowered into the house.
The easy cause manufactured housing is not extra widespread is that it is traditionally simpler to assemble stick-built houses. However development prices and labor have each risen, making the choice extra viable.
And so the economies of scale and standardization might make these houses cheaper to construct. Once more, in concept.
The issue, Berner says, is that each locality has a distinct zoning code, and so constructing “customary” merchandise may be very tough.
“To successfully run a manufacturing unit producing standardized houses, you want sufficient demand for a similar standardized residence to get previous the overhead prices of manufacturing in bulk in a manufacturing unit,” says Berner.
“Manufactured housing should function at scale to be cost-effective. However to realize that scale, there should be coverage certainty about what will be delivered.”
Authorized hurdles stay for factory-built houses
Important authorized hurdles stay for factory-built houses. On the Nationwide Housing Provide Summit, a bunch of modular homebuilders stated the enterprise is beset by a number of rule adjustments, regardless of regulatory strides lately.
CertainTeed, a Pennsylvania-based producer of panels and supplies, initiatives the demand for offsite development supplies to develop 8.5% a 12 months via the top of the last decade—nearly twice as quick as stick-built strategies.
That features extra demand for panelized parts, metal programs, and pre-cast concrete, says Dennis Michaud, managing director of offsite options for the corporate.
And the share of houses utilizing offsite supplies varies by area: 10.4% within the Midwest, 6.5% within the Northeast, 7.6% within the Southeast, 8.5% within the Pacific Northwest, and 1.7% within the Southwest.
Zoning adjustments carry hope, says Jenna Louie, head of technique and coverage at San Francisco-based Villa Properties. California permits manufactured housing by-right, and Villa has grown because it was launched within the ADU area in 2019.
It has constructed 400 items of houses in California and Colorado, together with city infill and bigger conventional developments. Its typical product is a 1,620-square-foot, two-bedroom “crossmod.” The house construction, patio, and deck are inbuilt a manufacturing unit, whereas the inspiration, storage, exterior, and roof are largely on-site.
The by-right zoning change stays a problem, although, as a result of solely a 3rd of states have or are contemplating the pliability. An equal quantity are opposed, Louie says. And the density generally is a sticking level—25 houses match on 2.5 acres with minimal tons.
“It isn’t all the time the manufacturing unit that is the difficulty; that is not the laborious half,” says Louie. “It is the system round it.”
Manufactured housing might revolutionize homebuilding
And but, current adjustments in housing legal guidelines carry hope to the business. Many legislation adjustments aimed toward cell houses find yourself benefiting factory-built housing, too.
Fannie Mae and Freddie Mac, just a few years in the past, opened manufactured housing to the identical typical financing applications as customary houses. That was an enormous change for each cell houses and off-site development.
Virginia simply signed a legislation that permits manufacturing housing by-right on land cited for different single-family houses.
Extra legal guidelines are coming, too. California unveiled a set of payments aimed toward serving to make modular and factory-built housing extra possible.
Then there are the trickle-down results from the bipartisan housing package deal caught in Congress. Its removing of the everlasting chassis requirement on cell houses may even make it simpler to construct multistory manufacturing unit houses, Louie stated.
Taken collectively, these legislation adjustments might create bigger markets with constant demand that enables the enterprise to scale up, says Berner.
“It isn’t a pipe dream,” he provides.
“Manufactured housing has the potential to revolutionize the best way we construct houses. They are often cheaper, safer, and get delivered extra shortly if homebuilders are in a position to scale up this know-how and method. The massive issues holding it again are perceptions and coverage, which may all the time be modified.”
