Michael Costa isn't waiting for a rebound in market-rate apartment construction. He doesn't need to. “We're focused 100 percent on workforce housing,” says Costa, president of Simpson Housing Solutions, a California-based subsidiary of Simpson Housing, a multi-family builder and developer based in Denver. Workforce housing, he explains, is designed for households making from 60 percent to 80 percent of the local median income. Many of these are younger people just entering the workforce. “The median home price in Los Angeles County is over $400,000 so these programs appeal to young people in these communities,” Costa says.
