While the current tariff war is justifiably on the minds of many Americans, another type of import tax may be coming later this summer that could have a big impact on new home construction. …The US is preparing to raise duties on Canadian softwood lumber from 14.5% to 34.45%. …A final review of the levies will be published in August or September, with the rate increase taking effect then, according to the National Association of Home Builders. The NAHB has previously estimated that Trump’s tariffs could increase the cost of building a new home by $9,200. ….The proposal to more than double the tax would be a blow to Canadians, but it would also mean “driving up housing costs for Americans,” BC Premier David Eby said. …Some have praised the proposal, suggesting that it will give domestic lumber companies an opportunity to increase production, even if that means higher costs.
