If 900,000 Construction Workers Are Deported, Who Builds America?

Approximately 900,000 undocumented workers currently contribute to U.S. construction, and their potential mass removal would eliminate an estimated $37 billion in annual tax revenue while creating an immediate workforce collapse with no viable replacement pipeline (Source: HCC Policy Analysis, 2026; American Community Survey; Pew Research Center, 2024).

I am not going to soften that number. $37 billion is what funds schools, roads, and social services in the communities where these workers live and build. That revenue disappears along with the workers.

The Chilling Effect Came Before the Deportations

What people outside the industry do not fully understand is that the damage was not waiting for mass enforcement actions. It started the moment enforcement rhetoric escalated.

I began hearing about it from HCC member contractors in early 2025. Workers who had shown up every Monday for years started calling in. Not sick. Just not coming. Job sites in Phoenix and Dallas that ran with 40 workers were showing up with 28. Foremen were covering for guys who weren't there. Project timelines were slipping before a single enforcement action had touched those specific sites.

What $37 Billion in Tax Revenue Actually Means

The $37 billion figure deserves context because it is often dismissed as an estimate rather than a real number.

Undocumented workers pay into Social Security, Medicare, and federal income tax systems through payroll deductions they can never claim benefits from. They pay sales taxes on every purchase. They pay property taxes through their rent. The Institute on Taxation and Economic Policy estimates that undocumented workers collectively contribute $96.7 billion in federal, state, and local taxes annually (Source: ITEP, 2024). The $37 billion attributable to construction workers is proportionate to their share of that total.

The communities that would lose this revenue are the same communities that already strain under inadequate school funding and infrastructure maintenance backlogs. There is no replacement source for those dollars.

The Replacement Pipeline Does Not Exist

This is the point I make every time I speak to a policymaker who believes enforcement can proceed without economic consequence: the replacement pipeline does not exist.

You cannot deport 900,000 construction workers and refill those positions from the domestic labor market. The industry already has 500,000 open positions it cannot fill (Source: HCC America's Construction Crisis Report, 2025). Adding 900,000 additional vacancies would create a combined shortage of approximately 1.4 million workers in an industry that currently employs about 12 million total. That is more than a 10% workforce reduction overnight.

The H-2B visa program, which is the primary legal pathway for temporary foreign construction workers, currently allows approximately 66,000 visas annually across all industries (Source: U.S. Department of Homeland Security, 2024). That is not close to a meaningful replacement mechanism.

What Contractors Are Telling Me Directly

I hear this directly from HCC member firms. General contractors in Florida, Texas, and California are doing something I have never seen them do before: they are beginning to factor workforce risk from immigration enforcement into their project bids.

I remember a specific phone call in February 2025 from a concrete subcontractor I have known for eight years. His company ran 41 workers. Nine of his most experienced people had not shown up that week. Not sick. Not on another job. Just gone. Two of them had texted him to say they were leaving the state. They were not waiting for enforcement to find them. They were leaving out of fear. My advice to every contractor who calls me with that story is the same: document the workforce losses with dates and numbers, because the policy conversation needs specific data, not generalities.

A large commercial contractor in Tampa told me his team now includes a line item in risk analysis for "workforce volatility due to enforcement climate." He bids accordingly. That means higher prices for the clients. Higher prices for the hospitals, schools, and government buildings being built. That cost flows to taxpayers.

The same contractor told me he had a subcontractor on a major healthcare project who simply stopped answering calls one week. Twelve workers. Gone. The general contractor had to scramble to find replacement labor. It cost him $180,000 in delays and premium labor rates to cover a three-week gap on a single subcontract.

The Policy Position HCC Advocates

HCC's position is specific and data-driven. We are not arguing for open borders or no immigration enforcement. We are arguing for policies that reflect economic reality.

First, work authorization pathways for construction workers with established employment records. Workers who have been paying taxes and building American infrastructure for 5, 10, or 15 years represent a known quantity. They are trained. They are experienced. They are building projects right now. A pathway to legal status for this group is not amnesty. It is workforce policy.

Second, H-2B visa expansion for construction. The current 66,000-visa annual cap across all industries is completely inadequate for a construction sector running a 500,000-job deficit. A construction-specific visa category with a capacity of 150,000 or more would begin to address the structural gap.

Third, a 24-month enforcement moratorium for workers with no criminal record who are currently employed on critical infrastructure projects. The Infrastructure Investment and Jobs Act projects cannot afford to lose their workforce mid-construction.

Who Builds America If They Leave?

That question is not rhetorical. It has a specific, data-backed answer: nobody replaces them on the current timeline. The domestic workforce is not available. The legal immigration pathway is not scaled for it. The apprenticeship pipeline is years away from producing replacements at scale.

The buildings that would not get built are not luxury condos. They are hospitals, schools, water treatment plants, and bridges. The people who would wait longest are the ones who can least afford to wait.

The Compounding Effect on an Already-Aging Workforce

This is happening at the worst possible moment for the construction industry's demographic pipeline. The average age of a U.S. construction worker is now 43, up from 40 in 2015 (Source: Bureau of Labor Statistics, 2024). The industry is aging out of its core workforce at the same time immigration enforcement is shrinking the replacement pool.

The workers most at risk from enforcement are disproportionately in the 25-to-44 age range, precisely the cohort the industry needs to stabilize its workforce over the next 15 years. They are not at the end of their careers. They are in the middle of them.

A masonry contractor in Phoenix I spoke with recently put it plainly. He has 34 employees. Eight of them have been with him for more than 10 years. He estimates that three or four would be directly at risk in a mass enforcement scenario. Those are not workers he can replace with a job posting. They are trained craftspeople who know his methods, his clients, and his job sites. The knowledge they carry does not transfer automatically to a new hire. It takes years to build. Losing it is not just a labor cost problem. It is a capacity problem that follows him into every project he bids.

The construction industry built its recovery after 2008 on the backs of workers who showed up when no one else would. Removing them now, without a scaled replacement pipeline, is not enforcement. It is a workforce crisis we are choosing to create.
