The Civil Justice Association of California this week announced its opposition to Proposition 10, the ballot measure that would repeal the Costa-Hawkins Rental Housing Act and bring extreme forms of rent control back to California.

“Prop 10 contains a hidden loophole requiring taxpayers to pay the initiative supporters’ legal bills for participating in certain lawsuits, even if they lose and even if their position is frivolous,” Caitlin Colman, vice president of government affairs for CJAC, said in a news release from the No On Prop 10 campaign. “This blank check benefits lawyers and puts taxpayers on the hook for limitless legal bills.”

By repealing the Costa-Hawkins Rental Housing Act, Prop 10 would allow cities to apply rent control to single-family homes and new multifamily housing. Cities would also be able to make rent caps permanent by enacting vacancy controls, which prevent landlords from returning rents to market rates between tenancies.

“Prop 10 also allows regulators to tell single-family homeowners how much they can charge to rent out a single room in their homes,” Colman notes. “Homeowners will be subject to regulations and price controls enacted by unelected boards that also will lead to more lawsuits and burdens on the justice system.”

CJAC joins a growing number of organizations opposed to Proposition 10. Earlier this month, the Los Angeles/Orange Counties Building and Construction Trades Council, one of the state’s most powerful unions, announced its stance against the proposition, as did LeadingAge California, a statewide association of more than 400 non-profit providers of senior housing.

In June, the State Building and Construction Trades Council of California joined efforts to defeat Proposition 10. Other key groups opposing Prop. 10 include the California NAACP, AMVETS Department of California, the American Legion Department of California, the California Council of Local Housing Finance Agencies, the American G.I. Forum of California, the California Chamber of Commerce and more than a dozen other veterans, labor, and housing groups.
