Residential starts plunged 12.3 percent to 1.17 million in June, the lowest in nine months, according to a new Housing Starts report from the Census Bureau and the Department of Housing and Urban Development (HUD) released Wednesday.

Building permits fell 2.2 percent to 1.27 million while single-family home starts decreased by 9.1 percent and multi-family home starts dropped 19.8 percent. In total, 1.26 million new houses were completed in June, unchanged from last month but 2.2 percent above what it was in June 2017.

“It’s alarming that the single-family construction permit growth is decelerating at a time when homeownership is rising and millennials are reaching their peak age to really enter the market and buy their first home,” said Freddie Mac Chief Economist Sam Khater. “The growing imbalance between demand and supply is the reason home prices continue to escalate.”
