State Farm has received more than 8,700 claims from the Los Angeles fires alone and paid more than $1 billion to customers, according to the company. The insurer expects to pay out significantly more, and the fires will be the costliest in the history of State Farm, the company said.

State Farm General, California’s largest insurance provider, has requested an emergency interim rate hike averaging 22% for homeowners from state officials on Monday, citing a “dire” financial situation after destructive Los Angeles wildfires last month.

The company is seeking rate increases of up to 22% for non-tenant homeowners, 15% for renters and condominium owners, and up to 38% for rental dwellings. Non-tenant homeowners are investors who don’t live in the property they own.
