The president has announced he will impose “reciprocal tariffs” on all nations on April 2. There is currently no procedure in place for how the tariffs will be implemented. …Tariffs on building materials act as a tax on American builders, home buyers and consumers. Builders estimate an average cost increase of $9,200 per home due to recent tariff actions, according to the March 2025 NAHB/Wells Fargo Housing Market Index. Of course, the effects of the tariffs on the housing industry go far beyond Canadian lumber. For example, 70% of the imports of gypsum, which is used to make drywall, comes from Mexico. …The tariffs are not only expected to raise the cost of building materials — which are up 34% since December 2020, far higher than the rate of inflation — but also wreak havoc on the building material supply chain. In turn, this will put even more upward price pressure on building materials. Here is what the NAHB doing.
