According to the National Association of Home Builders and Senators Jacky Rosen and Chris Coons, the Housing Tariff Exclusion Act was introduced in the Senate in late February 2026. The bill would automatically exempt many home building materials from current and future tariffs and create an application process for exclusions on other products. It is still a proposal and has not become law.
For the construction sector, the problem is straightforward: tariffs raise material costs, disrupt supply chains and make projects harder to price. According to NAHB, around 60 percent of builders have already reported cost increases linked to tariffs. The association argues that this is directly adding to housing costs for both buyers and renters.
The proposed solution is to carve out home building materials from the tariff regime. Under the bill, the Secretary of Commerce would have to establish a formal exclusion process. For commonly used building materials, exclusions would have to be granted within 15 days of application. For other products, the Secretary would be required to apply an objective process where tariffs increase the cost of home building in the United States. Businesses would also be allowed to seek reimbursement for tariffs already paid before an exclusion is granted.
For the construction sector, the significance is that the bill is aimed less at boosting demand and more at easing cost pressure on the supply side. In a market that still faces a housing shortage, lower material cost pressure could make new projects easier to price and support. That is the main logic behind the proposal as presented by NAHB and the bill’s sponsors.
