Data-center construction hit $80 billion. Homebuilders are paying for it.

A drywall contractor in Ohio spent last year supervising residential job sites. This year he runs a 200-worker data center build, makes six figures, and most of the electricians and HVAC techs he used to manage have followed him onto AI infrastructure sites.

Crews on data center projects earn 25% to 30% more than the same trades earn on homebuilding sites, according to the Wall Street Journal's pay data. A supervisor overseeing 200 workers on an Ohio data center site now makes more than $100,000 a year. An electrician managing crews across six sites in Northern Virginia tops $200,000. The math has gotten simple enough that trades workers are voting with their toolbelts.

Those trades are electricians, HVAC techs, and pipe layers, the same people who wire, heat, and plumb a new house. Industry analyses peg the data center sector's worker shortage at roughly 439,000 people this year, an ITIF estimate cited in the trade press. Data center construction starts approached $80 billion in 2025, nearly triple the prior year's figure, per ConstructConnect. The buildout is geographically spread across more than a dozen states, not concentrated in a few coastal tech hubs, which means the labor pressure is hitting homebuilders almost everywhere, not just in Loudoun County.

The sector's workforce has been shrinking and aging for the better part of a decade, and labor costs and timelines had already been creeping up before any of this. Realtor.com senior economist Joel Berner says the labor crunch is now a binding constraint on housing completions, not just starts. Homebuilders are competing for the same crews as the data center builders, and the data center builders are winning, per Realtor.com's analysis.

What that means for a buyer is concrete. A house that used to be framed, wired, and weather-sealed by the same regional crew now waits longer for that crew to become available, and pays more when it does. Electricians and HVAC installers are the two trades most often named as bottlenecks in builder cost-plus change orders, and both are pulling toward data center work where the premium is largest. Industry recruiter analyses track the shift regionally, with six-figure pay becoming routine for data center electrical and HVAC leads across Ohio, Texas, Virginia, and the Carolinas, and residential contractors reporting they have lost mid-career workers to those projects.

Nvidia CEO Jensen Huang predicted the next wave of six-figure jobs will come from crews building data centers, not from Silicon Valley. The paycheck data is already showing that reallocation in real time. The same trades that build a new house are being pulled off it.

Local opposition to data center construction has risen in parallel, with residents pushing back on power use, water consumption, and noise. Zoning battles and utility constraints are the more visible friction. The labor reallocation is slower and more personal: it shows up as a three-month delay on a closing, a change order that adds five figures to a build cost, or a builder that just stops taking new contracts in a market it used to serve.

The next housing-affordability report is going to read this as a labor cost line. It is one. The AI buildout has not made housing expensive on its own, but it is the highest-paying customer for a finite pool of skilled trades, and the residential side does not have a counter-offer that works.
