Tariffs raise home costs

Tariffs are adding thousands of dollars to the cost of building a new single-family house in the U.S., and builders say buyers are paying it. (nahb.org) The National Association of Home Builders said builders estimated in its March 2025 survey that recent tariff actions added about $9,200 per home. In its April 2025 materials, the group put the average at $10,900 per home. (nahb.org 1) (nahb.org 2) NAHB said about 7% of goods used in new residential construction in 2025 came from outside the U.S., and builders reported that more than 60% of them were already seeing tariff-related price increases. (nahb.org) (tradingeconomics.com) A tariff is a tax on imports, paid at the border by the importer. Builders’ trade group says that cost usually moves through suppliers and contractors and shows up in higher home prices, appliance prices, or both. (nahb.org) That pressure lands on a market where material costs were already elevated. NAHB said building-material prices had risen 46.1% since February 2020, compared with 24.7% inflation over the same stretch. (nahb.org) The tariff picture kept changing in 2025 and 2026. The White House said on April 2, 2026, that it was restructuring tariffs on aluminum, steel, and copper imports under Section 232, a national-security trade law first used for metals in 2018. (whitehouse.gov) Home construction uses all three metals in framing connectors, wiring, pipes, heating and cooling equipment, and appliances. NAHB’s housing-cost brief also lists imported lumber, fasteners, plywood, windows, doors, insulated copper wire, air-conditioning units, breakers, refrigerators, cabinets, and stone countertops among the exposed categories. (nahb.org) Denver agents and title professionals have been using the same math locally. A Denver real-estate post published in 2026 said tariffs were adding about $9,200 to a new home in that market, matching the March 2025 national builder survey. (milehightitleguy.com) (nahb.org) Builders have also pushed back on new wood tariffs. In September 2025, NAHB said the Commerce Department imposed a 10% tariff on all timber and lumber imports and an additional 25% tariff on kitchen cabinets and furniture, with cabinet levies scheduled to rise to 50% on January 1, 2026. (nahb.org) The result is not one single surcharge on a closing statement. It is a stack of higher costs on materials, components, and finished products that can turn a tariff change in Washington into a roughly $7,500 to $10,000-plus increase on a newly built house.
