Tariffs Threaten to Stall New Construction Gains in Home Affordability Nationwide

Key Takeaways

• Tariffs have increased material costs for construction by up to 9%, directly impacting home affordability.
• Rising expenses for essential building materials are causing project delays, cancellations, and higher housing prices in cities like Miami.
• First-time homebuyers are especially affected, as budget overruns and supply shortages limit their options.

The Ripple Effect of Tariffs on Housing Projects

Tariffs are hitting American construction like a wrecking ball at the Golden Gate Bridge, pushing material costs up by as much as 9% and slamming new home affordability. Building supplies—from steel beams to rooftop metals—now cost thousands more, sparking delays, project cancellations, and sending housing prices in Miami and beyond through the roof.

Homebuilders burn through budgets, while shortages choke the pipeline for first-time buyers.

If you want to know who’s next in line for these losses, pay close attention.

Tariffs Drive Up Construction Costs and Slow Builds

How quickly can the ground beneath Times Square—or any booming city center—shift when new tariffs hit construction’s foundation? In early 2025, sweeping U.S. tariffs slammed into steel, aluminum, and lumber, reshaping every phase of construction from steel framing in Midtown skyscrapers to humble plywood in Austin suburbs.

A 25% tariff now blankets all imported steel and aluminum, stripping away previous lifelines for builders who relied on Canadian, Mexican, or European suppliers. The new “melted and poured” standards set a chokehold, demanding rigid origin tracing, while general exclusions vanished—leaving nearly no escape route for struggling construction firms and downstream producers.

Material costs exploded, with nonresidential materials prices jumping 9% within mere months. Builders now face an average tariff rate of 22%, directly impacting roughly 7% of the imported homebuilding materials and equipment that form the backbone of new construction projects.

Developers feel the squeeze as higher steel and aluminum costs—critical for framing beams in the concrete jungles of cities like Chicago—hit project budgets hard. Those cost hikes move fast, pushing up prices for everything from residential rooftops to the glittering facades around the Space Needle.

Contract disputes surge as budgets are blown and timelines buckle. Increased regulatory enforcement targets duty evasion and misclassification, fueling market volatility and making supply chains less reliable.

The environmental impacts ripple outward as well. Sudden price hikes for key materials force builders to stockpile supplies, intensifying demand and contributing to increased greenhouse gas emissions at ports and warehouses from accelerated shipments and storage.

Urban construction sites face new labor shortages as contractors either renegotiate terms, cut overtime, or lay off skilled workers in reaction to slimmer margins—raising the specter of delayed openings for everything from luxury condos in Miami’s Brickell district to affordable housing projects for teachers in Denver.

On the residential front, the cost to build a new house has spiked by $6,400 to $9,200 per home. The average homebuilder now anticipates $9,200 in extra expenses per house, threatening the affordability of new listings and tightening builder margins in a market where the median sales price for new single-family homes hovers at $414,500.

Real estate investors now contend with stark regional imbalances. States depending on international sources—like Florida, Texas, and California—face the highest price shocks, while cities with robust local supply chains see far less impact.

Yet across the country, the dream of affordable new builds is fading. Buyers facing sticker shock in Atlanta’s Midtown or Los Angeles’ Koreatown are turning instead to existing homes, inflating competition and driving up prices there as well.

Developers racing to beat tariff hikes deplete supplies even further, intensifying shortages across critical regions.

Meanwhile, builders managing increased regulatory scrutiny and diminished exemption flexibility find traditional partnerships—like those with Canada’s mills or European steel giants—suddenly fraught with risk.

Market volatility grows more severe with each delay or contract dispute, leaving construction timelines uncertain and development budgets on edge.

Environmental impacts, labor shortages, and mounting costs churn through the real estate economy like a storm rolling over the Golden Gate.

As long-term volatility persists, affordability slips further from reach, and pressure mounts—demanding swift, decisive change before the skyline’s next chapter is written in red ink.

Birmingham’s housing inventory declined by 22% year-over-year, a stark reminder of the knock-on effects that nationwide material shortages and price shocks have on even the strongest local markets.

Assessment

From the Gateway Arch to Main Street, you can hear the concern—tariffs are tightening their grip on the housing market, and it’s hitting hard.

Construction costs keep rising, making homes less affordable and putting the brakes on new projects.

Neighborhoods watch as more empty lots appear, while builders hesitate and investors face the risk of real losses.

At the same time, families looking to buy a home are seeing their dreams slip further out of reach.

The industry is at a crossroads, and not addressing tariffs could mean lasting consequences.

It’s time to speak up and take action—addressing these tariffs is urgent if we want to keep the American dream of homeownership alive for everyone.
