San Francisco supervisors voted Tuesday to support Proposition 10, a measure on the California ballot this November that allows for the expansion of rent control across the state.

The nonbinding resolution to support the initiative, which was spearheaded by Supervisor Aaron Peskin, passed on a 9-2 vote, with Supervisors Katy Tang and Catherine Stefani opposing the measure.

Peskin says rent control is essential to maintaining affordable housing in the state.

"San Francisco and many cities in California have become terribly unaffordable and we have rising rents and a housing crisis," Peskin said. "One of the quickest ways that it can be addressed is through reasonable rent control protections."

Proposition 10 would repeal the 1995 Costa-Hawkins Rental Housing Act, which curtails the ability of local governments in California to expand rent control. Currently, new rent control restrictions cannot be placed on homes built after 1995. The law also allows landlords to increase rental prices to market rates when tenants move out.
