Chapman University’s economic forecast has a decidedly different warning for the California economy: There may be no housing shortage.

The school’s semi-annual forecast has a relatively upbeat outlook for the state’s real estate market in 2020. After that, says Chapman economist Jim Doti, he sees a chance of “severe weakness” for the state’s real estate markets as demand for housing dries up as California’s population growth comes to a near halt.

The cooling is already here. Just look at construction staffing statewide, for example. Bosses will hire 17,000 workers in 2020, Chapman forecasts. That’s down from 27,000 this year and 50,000 in 2018.

One key reason for that chill is residential building is stagnant.

Chapman projects statewide permitting at 115,000 units in 2020, up from 109,000 this year but down from 119,000 in 2018. And it’s nowhere near the statewide need of some 500,000 new units per year as suggested by Gov. Gavin Newsom to put a lid on the state’s high housing costs. Doti says that level is both illogical and would be impossible to pull off, even it was plausible.

He delivered the school’s 42 annual forecast Tuesday, Dec. 10 at the Segerstrom Center for the Arts in Costa Mesa where he told the audience California’s government needs to “get out of the way” and “let the free market work itself out.”

Gauging housing demand is no mere academic exercise as the state is in the process of setting homebuilding targets for counties and cities. And remember that developers won’t build housing unless it’s profitable — regardless of regulatory demands or societal dreams.

Proposed state goals say six Southern California counties must add 1.34 million units in a decade. These construction minimums have been cheered by folks seeking more housing and criticized by local officials who claim the region cannot support, economically or logistically, that kind of expansion.

Look, it was just a decade ago that the region was swamped with unsold homes and falling rents amid the Great Recession’s economic destruction. So housing demand is by no means guaranteed.

Doti’s doubts about any significant housing needs can be tied to his concerns for California’s growing net loss of residents to other states, especially departures to places with lower taxes and a cheaper cost of living.

This longtime watcher of the region’s economy notes these losses come as foreign in-migration slows with a national backdrop of fewer births and more deaths. Plus, demographics suggest there’s a cohort of older Californians who’ll soon become home sellers … or their heirs will be.

“Fewer people translates to fewer homes,” says Chapman’s report. “Rather than there being a housing shortage in California as many people claim, it increasingly looks like the pendulum is swinging in the other direction. That may explain why housing construction in the state isn’t showing much strength in spite of record-low mortgage rates.”

Another sign of limited demand: California’s house-price gains will remain modest, according to the Chapman forecast. House appreciation will gain 3.9% in 2020 after 2.8% this year and 6.3% in 2018.

That tame real estate outlook also can be tied to a slower hiring pace statewide — 268,000 new jobs next year, the lowest in the recovery from the Great Recession — and fewer pay hikes with 4.6% forecast income growth, the lowest since 2016.
