Insurance companies that stopped providing home coverage to hundreds of thousands of Californians in recent years as wildfires became more destructive will have to again provide policies in fire-prone areas if they want to keep doing business in California under a state regulation announced Monday. The rule will require home insurers to offer coverage in high-risk areas, something the state has never done, Insurance Commissioner Ricardo Lara's office said in a statement. Insurers will have to start increasing their coverage by 5% every two years until they hit the equivalent of 85% of their market share. . In exchange for increasing coverage, the state will let insurance companies pass on the costs of reinsurance to California consumers. Opponents of the rule say that could hike premiums by 40% and doesn't require new policies to be written at a fast enough pace
