Construction robots are tackling America's housing shortage

America's housing industry is under pressure to build more homes with a shrinking pool of skilled labor. Robotics and automation offer one potential answer, but the biggest gains so far are not coming from humanoid robots replacing workers on construction sites.

They are coming from narrower applications: machines that prevent mistakes, coordinate trades, and automate repetitive work, along with factories that move more of the construction process into controlled environments, say industry experts. Yet when asked whether robotics is already meaningfully improving homebuilding productivity, Dietz.

What Happened

The results so far suggest robotics can produce meaningful gains on individual projects, but those gains remain too narrow and too limited in scale to materially reduce the national housing shortage. Tessa Lau, founder of Dusty Robotics, spent years working in robotics.

• The United States is short roughly 1.2 million homes, according to the National Association of Home Builders 2026 Housing Outlook.

• Nearly 300,000 construction jobs remained open at the end of 2025, and NAHB estimates the industry needs to attract roughly 740,000 workers a year to account for growth, retirements, and workers leaving the field.

• That labor gap compounds a decades-old productivity problem: Residential construction productivity has increased only about 16% since 1993, compared with gains of more than 50% across the overall economy, according to NAHB chief economist.

Key Details

She said factories are relatively easy to automate because robots can perform the same task repeatedly in a fixed environment. Construction is the opposite: The robot's workplace is literally being transformed around it.

• Labor shortages alone cost homebuilders about $11 billion a year through higher costs and lost production and add roughly two months to the average construction timeline, Dietz said.

• Dusty Robotics says one operator can lay out roughly 10,000 to 15,000 square feet a day, up to 10 times faster than traditional methods.

• After using Dusty's multi-trade layout system, global construction company Skanska reported a 75% reduction in rework and a 35% reduction in its layout schedule.

Why It Matters

Patrick Murphy, chief investment officer of Florida-based Coastal Construction, sees the same problem from the builders' side. Every project can involve different designs, soil conditions, architects, subcontractors, materials, and owner requirements, he said, explaining that the lack of uniformity makes repetitive automation.

• "We're in that prove-it phase," he said.

• Getting the full benefit requires coordination and buy-in from multiple trades, he said, and the industry does not yet have enough data to put hard numbers on all of the savings.
