Many insurance companies have stopped issuing new policies to homeowners in other vulnerable states, including Louisiana and Florida. The wildfires that have devastated large parts of Los Angeles County have drawn fresh attention to the struggles many Americans face insuring their homes.

California Insurance Commissioner Ricardo Lara said new regulations will keep homeowners insured. Some of the new efforts give insurance companies more leeway in raising rates, while allowing them to use computer modeling to forecast risk and to incorporate their own “reinsurance” costs from backup providers in setting future premiums.
