In a poll released this week, a statewide ballot measure that would repeal the Costa-Hawkins Rental Housing Act continued to trail by a wide margin.

The final pre-election Berkeley Institute of Governmental Studies Poll, published Wednesday, indicated that 60 percent of likely voters oppose Proposition 10, while 35 percent support the measure, and 5 percent are undecided.

“This poll mirrors public and private polling that shows voters clearly understand that Prop 10 is a flawed measure that would worsen California’s affordable housing crisis, reducing property values and freezing the construction of housing for low- and middle-income families that we desperately need,” Steven Maviglio, spokesman for the No on Prop 10 campaign, said in a statement. “Instead of focusing on real solutions to boost the availability and affordability of housing in our state, anti-housing advocate Michael Weinstein and the AIDS Healthcare Foundation has squandered more than $23 million on this measure that will not result in a single new unit of housing or help the homeless.”

If Costa-Hawkins is overturned in the November election, California cities and counties will once again gain the authority to adopt extreme forms of rent control, including the imposition of rent caps on new apartments and single-family homes. Such moves would stifle housing development and exacerbate the state’s housing shortage.

The Berkeley IGS Poll was completed online in English and Spanish Oct. 19-26 among 1,339 likely voters statewide.

Earlier this month, a poll by the Public Policy Institute of California also indicated that 60 percent of likely voters would vote no on Prop 10. Opposition to the measure has grown since September, when an earlier PPIC poll showed 48 percent of likely voters rejecting the initiative.
