Developer Greg Drobot hope to sell the houses they’re building in Coos Bay for around $400,000. …Keeping costs down means paying attention to the price for every detail. Drobot said instead of plywood, the project was going to use a less-expensive oriented strand board from Canada. “When the tariffs hit, it made it almost cost-prohibitive for us to use that,” Drobot said. …Tariffs are almost certain to put Oregon’s new home construction goal further out of reach. Imported components are going up in price, as are the tools and equipment needed to build new homes. Gov. Tina Kotek said she’s concerned tariffs will make it harder and more expensive to get materials like wood — even though Oregon produces some wood products. …Drobert’s project has about a 15% contingency on cost… If prices go up more than that, he will pass on the cost to the homebuyer or find ways to cut costs.
