Construction robots are hitting America’s housing shortage

The U.S. housing industry is under pressure to build more homes with a shrinking skilled workforce. Robotics and automation offer one potential answer, but the biggest benefits so far aren’t coming from humanoid robots replacing workers on construction sites.

Industry experts say they’re coming from narrower applications, such as machines that prevent mistakes, coordinate transactions and automate repetitive tasks, and factories that move much of the construction process into controlled environments.

According to the National Association of Home Builders’ 2026 Housing Outlook, there is a shortage of approximately 1.2 million homes in the United States. Nearly 300,000 construction jobs remain at the end of 2025, and NAHB estimates that the industry will need to attract approximately 740,000 workers annually to account for growth, retirement, and workers leaving the field.

This labor disparity is exacerbating decades-old productivity problems. Robert Dietz, chief economist at NAHB, said productivity in housing construction has increased by only about 16% since 1993, compared with more than 50% in the economy as a whole.

The labor shortage alone costs home builders about $11 billion a year in higher costs and lower production, and adds about two months to average construction schedules, Dietz said.

But when asked if robotics was already meaningfully increasing productivity in home construction, Dietz said, “It’s too early.”

“There is no single, simple, scalable solution,” he said, citing labor, regulatory costs, land availability, supply chains and financing as additional constraints to housing production.

While results so far suggest that robotics has the potential to generate meaningful benefits in individual projects, the benefits remain too narrow and too limited in scale to substantially alleviate the national housing shortage.

Why robots still struggle on construction sites

Unlike factories, construction sites change on a daily basis.

Tessa Lau, founder of Dusty Robotics, worked in the field of robotics for years before turning to construction. He said automating factories is relatively easy because robots can perform the same tasks repeatedly in a fixed environment. Construction is the opposite. The robot workplace is literally being transformed around robots.

Patrick Murphy, chief investment officer at Florida-based Coastal Construction, sees the same problem on the construction side. He explained that every project can involve different design, soil conditions, architect, subcontractor, material, and owner requirements, and the lack of uniformity makes iterative automation difficult.

This variation helps explain where measurable gains are emerging. Vineet Kamat, a professor at the University of Michigan who studies construction robotics, said the clearest results today are in highly repetitive, well-structured tasks, including layout, factory automation, and task-specific applications such as drilling, fastening, and material handling.

The biggest benefits, he said, aren’t complete labor replacement, but improved accuracy, fewer errors and increased throughput.

“The key question is not whether the robot can operate experimentally, but whether it can operate reliably under a variety of conditions based on a positive business case,” Kamat said.

But Murphy said the public image of construction robots far exceeds that reality. “The biggest misconception is people imagining humanoid robots walking around job sites hanging drywall and painting. We’re still years away from being in that world.”

Where robotics saves time and mistakes

Lau’s idea for Dusty Robotics was born from a mistake he encountered while renovating his home.

In one case, a plumber installed the wrong fixtures in two bathrooms. Lau didn’t realize the mistake until the bathtub was tiled. Workers had to scrape away tiles, remove and reinstall fixtures, and retile bathrooms.

“That’s a misinformation,” Lau said.

She realized that the problem was not the finish, but information being lost between the people doing the planning and work. She created FieldPrinter to fill that gap. Dusty’s FieldPrinter takes digital architectural plans and prints them directly onto the floor. Mark walls, plumbing, electrical and mechanical locations with text, images and QR codes, and give multiple traders the same instructions so they can see exactly what is where.

“If you don’t think too deeply about it, the shallow view is that labor replacement is the solution,” Lau said. “But when we actually dug a little deeper into the construction issue, we found that the issue wasn’t about labor replacement, it was about standardization.”

According to Dusty Robotics, one operator can layout approximately 10,000 to 15,000 square feet per day, up to 10 times faster than traditional methods.

Skanska, a global construction company, reported a 75% reduction in rework and a 35% reduction in layout schedules after using Dusty’s multi-trade layout system.

Aaron Love, president and CEO of Oh Snap Layout, is leveraging this technology to build homes in Southern California, combining robotic layout with prefabricated wall panels, pre-cut lumber, and other off-site construction methods.

But Love said simply replacing chalk line cutters with robots would only provide part of the potential benefits. Having your frame contractors, electricians, plumbers, and HVAC contractors all working in the same coordinated layout reduces duplication of effort and trade-to-trade interactions, resulting in greater profits.

One example is RapidShell, a home building system offered by Reliable Wholesale Lumber. It combines Dusty’s robotic layout with pre-cut material packages, prefabricated wall panels, stairs, and other field-prepared components.

Love said the process has reduced the time it takes to build a shell from about 21 days to about 11 to 12 days.

But Love said builders are still determining how much these efficiencies will ultimately save them throughout the construction process. He said that maximizing the benefits would require coordination and buy-in from multiple exchanges, but the industry doesn’t yet have enough data to put hard numbers on all the savings. “We’re in the demonstration phase of that,” he said.

Maximum profits are generated within the factory, led by Japan.

An aging workforce and shrinking labor pool have inevitably made Japan the world leader in home-building robots. Japanese developers are treating home construction like an advanced car assembly line, building 80% of their homes entirely robotically in highly controlled factory environments before final assembly on-site. Within these factories, major homebuilders such as Sekisui Heim leverage automation for welding, structural framing, and material handling.

Kawasaki Robotics, which supplies the equipment, says the use of industrial robots at one of its factories has increased production from 55 to 65 housing units per day and reduced the number of operators by 20. Sekisui Heim estimates that the investment in the robot will pay for itself in about three years.

“It’s a little less sexy, but we’re seeing some great progress,” Murphy said of factory automation. He cited examples such as factory-made wall systems and prefabricated bathrooms, kitchens, and laundry pods.

Murphy, who is also managing director of Lenco USA, a composite building system whose components are manufactured in an automated facility in Palm Beach County, Florida, said the facility can produce materials for about 7,000 homes a year.

Murphy said Lenco structures can be built in about one-sixth of the time required for traditional wood, concrete or metal frames, reducing the total construction schedule by about 30% to 40%.

Factory-built components can also speed up non-automated tasks. If a room is designed to measure 10 feet by 10 feet and is to be completed to those exact dimensions, windows, doors, cabinets, tiles and other components can be prefabricated, Murphy said.

“Time is money,” he said. “A compressed schedule means lower financing costs and reduced expenses associated with maintaining site operations.”

But Murphy said the time and cost savings of prefabrication are lost when the design changes, explaining that if the owner changes dimensions, fixtures or finishes, the manufacturer has to redesign and reprogram the system, which can reduce the efficiency of repetition.

That’s why district housing, multifamily developments and other projects with repeated designs could be among the first to benefit on a large scale, he said.

Vineet Kamat, a professor of construction management and sustainability at the University of Michigan, expects robotics to increase housing production over the next five to 10 years, but that will come through targeted productivity improvements rather than industry-wide transformation. He said factory automation, prefabrication and robotic layouts are likely to advance most rapidly, while robots in the field will be the first to become widespread in repetitive, physically demanding tasks and tasks that require precision.

But Murphy doesn’t expect increased automation to eliminate the need for skilled construction workers.

“I think this is probably the best decade ever for blue-collar jobs,” he said. “Welders, electricians, plumbers, people will be working on-site for some time where the rubber meets the road on construction sites.”
