Tariffs on construction materials are back in the spotlight, but for builders, the real issue isn’t just higher costs—it’s uncertainty.
Recent estimates of tariff impacts vary widely.
Some forecasts suggest tariffs could add as much as $17,500 to the cost of a new home, while data from the National Association of Home Builders puts the range closer to $7,500–$10,900.
Even large public builders are offering more modest projections, with PulteGroup estimating potential increases of around $1,500 per home beginning in 2026.
Why such a wide spread of ranges? Because tariffs don’t hit the job site all at once.
Steel, aluminum, lumber, copper, and cabinetry tariffs have been announced, adjusted, paused, and re-announced—sometimes within months. That makes it difficult for economists, suppliers, and builders to model long-term impacts with confidence.
As NAHB’s chief economist has noted, uncertainty itself carries a cost. When rules keep changing, pricing risk increases—even before materials do.
So far, tariffs haven’t meaningfully pushed up home prices. Lumber prices are down from recent peaks. Steel spiked, then fell. Aluminum has climbed more steadily. The inflation many expected has not yet arrived.
But that doesn’t mean it won’t.
Tariff impacts tend to move slowly through the supply chain. As suppliers lose the ability to absorb costs, costs will eventually rise—and smaller builders are likely to feel it first, lacking the long-term contracts and purchasing power of national firms.
For builders heading into 2026, the takeaway is clear: the risk isn’t a single number—it’s volatility. Planning for flexibility, margin pressure, and timing risk may matter more than any one forecast.
