Building a new home in the U.S. now comes with a hidden price tag: tariffs.
These import taxes on materials like lumber, steel, and aluminum are quietly inflating construction costs.
On average, they add more than $9,000 to the price of a single-family home.

As home affordability remains a pressing issue, these extra costs are hitting at exactly the wrong time.
In most cases, companies pass along these added costs to their customers rather than absorb them.
For homebuilding, this means higher prices for the raw materials used to construct houses.
Builders then face higher expenses and often have to raise the homes sale price to make a profit.
This principle applies to many items that go into a house.
Tariffs also affect prices indirectly.
Even materials made in the USA can become more expensive when similar imported goods have tariffs.
Several of these directly hit construction materials essential for homebuilding.
These tariffs initially averaged about 20%.
Canada supplies roughly 2530% of the softwood lumber used in U.S. home construction, so this was significant.
Lumber prices quickly jumped.
NAHBs chief economist noted that the 21% lumber tariff was the biggest factor behind those price hikes.
Although lumber prices have fluctuated, tariffs remain.
The tariffs made metal products more expensive for builders almost overnight.
Domestically produced steel and aluminum also rose in price because imported options were pricier.
Every piece of rebar in a foundation or aluminum gutter now cost more.
All together, metal tariffs account for a few thousand dollars of the extra cost in a new house.
The tariffs on Chinese goods (often 10% to 25%) hit many items used in homebuilding.
This includes things like lighting fixtures, plumbing parts, kitchen cabinets, countertops, flooring, and appliances.
Those now have higher prices due to tariffs.
Likewise, tariffs applied to imported quartz countertops or vinyl flooring mean higher costs for new kitchens and bathrooms.
Even products from other countries have been affected by newer tariff moves.
Although Canada and Mexico were to be exempt in that plan, countries like China would see extra fees.
This broad increase translates into several thousand dollars added to building each home.
It represents the cumulative effect of the tariffs on lumber, steel, aluminum, and other goods.
Of that, roughly $12,700 worth of materials are imported from other countries.
Tariffs make those imported materials more expensive.
But the $9,200 figure also reflectsindirect price increases.
Recent data back this up.
Using that rule of thumb, an extra $9,200 could price out roughly nine times that number.
Price Volatility and Pandemic Effects
Homebuilders have certainly felt the squeeze.
Lumber prices hit record highs in the spring of 2021.
That spike was temporary and eventually eased, but it left its mark.
It showed how vulnerable the construction industry is to supply shocks.
Tariffs exacerbated that situation by limiting alternative supply options.
This means new homes never fully regained the lower costs; a tariff-induced premium remains built into prices.
By late 2022 and into 2023, material prices started stabilizing, but at a high plateau.
In early 2025, as new tariffs were proposed again, lumber prices began climbing in anticipation.
Western spruce-pine-fir lumber, for example, jumped over 60% year-over-year in one period.
Price volatility became a problem, with builders unable to predict costs confidently.
Effects on Homebuyers and the Housing Market
Higher construction costs from tariffs have several ripple effects.
Homebuyers who do go forward often face higher mortgage payments because the overall price is higher.
Over a 30-year loan, an extra $9,200 adds to the monthly payment and amount of interest paid.
Essentially, buyers are financing the tariff costs over the life of their mortgage.
For homebuilders and construction companies, tariffs create a tough business environment.
Builders operate on relatively thin profit margins, especially for entry-level homes.
When material costs jump, profits shrink unless home prices are raised.
Impact on Construction Activity
Tariffs have also contributed to builder uncertainty and lower confidence in the market.
In late 2022, builder confidence fell to its lowest levels in over a decade.
Home construction activity has been dampened by these cost issues.
For example, in March 2025, single-family housing starts fell to their lowest rate in eight months.
In normal times, lower interest rates spur more building, but tariffs were counteracting that benefit.
This dynamic contributes to a tighter housing supply.
With a tariff, it comes back with an added cost, which local builders must pay.
These regions saw a boost in business when Canadian lumber got pricier, as U.S. mills ramped up production.
However, this doesnt mean homebuilders in those states were spared higher costs.
Domestic lumber prices rose nationwide because demand shifted to U.S. suppliers and overall supply was still tight.
These states consistently lead the nation in the number of new homes built each year.
A Texas builder constructing large numbers of homes will cumulatively pay millions more in material costs due to tariffs.
So tariffs have a relatively larger impact on the final price of homes in cheaper markets.
As of 2025, the prospect of even higher or additional tariffs looms.
For instance, U.S. officials have been reviewing whether to raise the existing lumber tariffs substantially.
They argue that doing so would immediately help improve housing affordability by lowering the cost of lumber.
So far, these efforts have not resulted in a deal, and the tariff remains in place.
Some experts also caution that uncertainty around tariffs could lead to greater volatility.
The UBS Chief Investment Office noted in 2025 that tariffs were a major unknown for the housing market.
Some are using alternative materials or methods to reduce dependence on tariffed imports.
For instance, theres interest in engineered wood products or metal framing as substitutes if they become cost-competitive.
Conclusion
Homebuyers and builders alike have essentially absorbed the tariff costs into their expectations now.
When planning a new development or shopping for a new home, people know that prices are high.
The roughly $9,200 tariff impact is baked into the market.
Keeping an eye on policy changes is important.
For now, though, its clear that tariffs introduced since 2017 have reshaped the economics of homebuilding.
