Homebuilders Warn of 40% Tariff on Canadian Lumber and Its Impact on Housing Costs

 

The National Association of Home Builders (NAHB) has issued a warning about rising tariffs on Canadian lumber, which could soon reach 40% when combined with existing duties. This increase is expected to raise construction costs and impact home prices, particularly for entry-level and affordable housing.

Currently, while an additional 25% tariff has been announced for goods from both Canada and Mexico, the Mexican tariffs are temporarily on hold due to ongoing negotiations. However, the increased Canadian tariffs are moving forward and are a top concern for homebuilders. With over 70% of softwood lumber and drywall materials imported from Canada, the consequences could be significant.

Why Are Canadian Lumber Tariffs Increasing?

The latest tariff hike results from a 25% increase imposed on Canadian goods, compounding pre-existing duties on Canadian lumber. This will bring the overall tariff on Canadian lumber imports to 40%, which directly affects the cost of essential building materials in the U.S.

Carl Harris, Chairman of the NAHB, emphasized that the new tariffs contradict efforts to make housing more affordable.

“On President Trump’s first day in office, he issued an executive order directing departments and agencies to deliver emergency price relief by pursuing actions to lower the cost of housing and increase housing supply. This move to raise tariffs by 25 percent on Canadian and Mexican goods will have the opposite effect,” Harris said (Carter, 2025). 

The ongoing trade negotiations with Canada have yet to reach a resolution. Meanwhile, Canada plans to retaliate by imposing 25% tariffs on $30 billion worth of U.S. goods.

 

The Role of Canadian Lumber in U.S. Construction

Canada is the largest supplier of softwood lumber and gypsum for drywall in the U.S. These materials are vital to framing homes and constructing interiors. With rising tariffs, builders face higher costs that will likely be passed on to buyers in the form of increased home prices.

The NAHB emphasizes that these higher material costs will reduce the supply of affordable housing and discourage new development. Builders may prioritize higher-margin, more expensive homes to offset increased costs, leaving fewer affordable options for first-time and budget-conscious buyers.

Impact on Different Housing Segments

The tariffs will not affect all housing equally. Entry-level and affordable homes, which rely heavily on cost-effective materials, are expected to face the biggest challenges.

  • First-time buyers and budget-conscious buyers: Rising home prices could push these groups out of the market entirely.

  • Affordable housing developers: Increased construction costs will make it harder to build low-income or subsidized housing, worsening housing shortages in already tight markets.

  • Move-up buyers and higher-income buyers: While they may still face rising costs, this group may have more flexibility to absorb higher prices, especially in competitive markets.

 

How Builders and Policymakers Are Responding

Homebuilders and trade organizations are urging policymakers to reconsider the tariffs. The NAHB is advocating for the exemption of building materials from these trade measures to prevent further strain on the housing market. The organization continues to push for legislative support to eliminate barriers that increase construction costs.

Diplomatic and Trade Developments

Negotiations between the U.S. and Canada are ongoing, with Canadian Prime Minister Justin Trudeau in discussions to potentially ease tensions. Meanwhile, Mexican tariffs are temporarily suspended after Mexico agreed to deploy additional troops to the U.S. border.

The next few months will be critical for determining whether diplomatic efforts can ease trade restrictions. However, if tariffs persist, the U.S. housing market may face prolonged affordability challenges.

Bottomline

A potential 40% tariff on Canadian lumber could have serious implications for the housing market, particularly for entry-level and affordable housing. Higher construction costs may limit new development and drive up home prices, leaving first-time and budget-conscious buyers in a tougher spot.

As negotiations continue, builders, buyers, and investors should stay informed about changes in trade policy that could affect housing affordability and supply. In the meantime, understanding market conditions and planning ahead are essential.
