California's Department of Insurance has changed its rules to stop the public from challenging insurance rate increases below seven percent, shifting how the state oversees pricing for auto, home, renters, and medical malpractice insurance. The Department finalized the regulation in late October 2026, issuing a release on October 27, 2026, with Consumer Watchdog responding on October 29, 2026.
Consumer Watchdog, a nonprofit advocacy group, says this new process would have blocked $2.6 billion in consumer savings that came from public challenges to sub-seven percent rate hikes over the past 24 years. This figure comes from Consumer Watchdog and is not an official government statistic. The group argues the rule removes a key protection set by Proposition 103, which gave the public the right to contest insurance company calculations and Department decisions on rate increases. Proposition 103, passed by California voters in 1988, is the main law for property-and-casualty insurance rate oversight and created a system for consumer and advocacy-group participation in challenges to proposed rate increases. California is one of 11 states with an elected insurance commissioner, a role created by this initiative.
Regulatory Shift and Process Details
The regulation sets up an alternate rate review system. In this setup, the Department of Insurance completes a full rate analysis before any public notice goes out. This pre-approval process can last up to 167 days, and public intervenors cannot participate or submit information during this time. The public only gets notice after the insurer files a formal rate application, but for increases below seven percent, approval comes within 60 days—often before public participants can take any real action. The entire alternate process for sub-seven percent increases could last up to 227 days from the start of analysis to final approval.
Public hearings, which allow for deeper scrutiny and new information, now apply only to rate increases of seven percent or more. For smaller increases, the public's role is reduced to a late-stage formality, according to critics. The Department's structure lets insurers use the alternate pathway twice a year, which could encourage companies to submit repeated increases of 6.9% or less to avoid the tougher public challenge process. Consumer Watchdog describes this as letting insurers "seek two rate hikes every year" and possibly encouraging "serial rate increase requests of 6.9% or more to avoid public scrutiny."
Under the alternate system, the Department is still supposed to do a full analysis of sub-seven percent filings, but intervenors cannot participate during the main review phase. This is a clear change from the previous system, where public participants could contribute during the Department's initial actuarial and legal review. The threshold applies specifically to the public-hearing and intervention aspects of rate increases below seven percent, not to all Department review of those filings.
Consumer and Advocacy Group Response
Carmen Balber, executive director of Consumer Watchdog, called the regulation a "rubber stamp to a decision already made without them," saying it weakens the public's ability to check the math behind insurance rate hikes. Robert Herrell, executive director of the Consumer Federation of California, criticized the rule's adoption process, pointing to the lack of advance notice, hearings, or public comment. He argued that the private adoption process was set up to "eliminate the voices of consumers" and make private deals between the Department and insurance companies easier.
Marcus Friedman, administrative director at the Consumer Protection Policy Center at the University of San Diego School of Law, said the regulation appears to use legislative exceptions to get around the Administrative Procedure Act, after a previous legislative attempt to weaken the consumer intervenor process was withdrawn.
Potential Impact and Industry Incentives
Insurance companies can now use the alternate system to seek two rate increases per year, each just under the seven percent threshold, which could help them avoid public scrutiny. The total approval process for these increases could last up to 227 days, but intervenors cannot participate in the main review phase for any increase below seven percent. The Department of Insurance says the alternate process keeps the intervenor system, while Consumer Watchdog says intervenors are left out during the Department's initial analysis.
Consumer Watchdog argues that the regulation goes further than a failed 2024 Budget Trailer Bill, which also aimed to exclude public input on smaller rate hikes. Unlike the bill, the new rule fully excludes intervenors from the core rate review process for these increases.
The Department of Insurance filed the final rule directly with the Office of Administrative Law, skipping public review. Consumer advocates say this move violates both Proposition 103 and the Administrative Procedures Act, raising questions about the future of consumer oversight in California's insurance market. The Department's authority is especially important for homeowners and automobile insurance, as it reviews proposed rate changes in those markets under Proposition 103. The Department also licenses and regulates insurers, investigates complaints, and enforces state insurance laws, according to Capital Public Radio.
For comparison, federal Affordable Care Act regulations generally require health-insurance rate increases to be reviewed at a 15% threshold unless a state-specific threshold applies, and require aggregation of increases over a 12-month period. These federal rules cover health-plan rate review and do not apply to California's property-and-casualty lines like auto and homeowners insurance. More information on federal rate review rules is available in the Electronic Code of Federal Regulations.
