The insurance company has filed for an increase on personal umbrella liability coverage, affecting hundreds of thousands of California households. Meanwhile, State Farm will participate in a hearing Tuesday to decide whether homeowners and renters in the state will see rates rise on average hundreds of dollars a year.

If approved, it’s unclear how much premiums could go up in the Bay Area or which parts of the region would see the largest rate hikes, which could take effect as early as June 1 for many homeowners. Statewide, the insurer covers roughly 15% of homes, totaling more than 1 million customers.
