The California insurance rate review process will publish the Department of Insurance’s own analysis of proposed premium increases before insurers file them formally. Commissioner Ricardo Lara announced the Comprehensiveness Review Regulation on 19 October 2026, after the state’s Office of Administrative Law approved it. Taking part is voluntary for insurers.
What the Comprehensiveness Review Actually Is
It is an optional step an insurer may take before filing a rate application, not a new requirement. The regulation covers personal and commercial lines in California, and it sits ahead of the formal review that Proposition 103 — the 1988 ballot measure requiring the Department’s prior approval of property and casualty rates — already mandates.
An insurer that skips the voluntary step files directly and is reviewed exactly as before. Nothing in the regulation obliges any company to use it, and the Department has not said how many it expects to.
The Steps the Department Describes
The Department’s own account of the sequence runs as follows.
- Submission: An insurer voluntarily brings a proposed rate change to the Department before any formal filing.
- Front-loaded information: The company supplies supporting material upfront, so reviewers do not begin by asking for it.
- Analysis: Staff examine the proposal and flag problems, such as inflated cost projections or provisions that do not comply with California law.
- Rate range indication: The Department produces an initial range it considers supportable, and publishes it.
- Insurer’s choice: The company either accepts the Department’s figures or submits more material to support its own.
The Department says this complements its Complete Rate Application Regulation, in effect since 2024, which requires a full information set before an application is publicly noticed.
What Becomes Public, and What Does Not
What goes online is the regulator’s assessment, not the insurer’s filing. The Department said it will post, on its public website, the issues it flags in each submission, its initial rate range indications, and the rate savings its staff predict, in dollars.
Lara said “every dollar Californians pay for insurance should be justified” and that “government works best when people can see it working”. The release states the Department’s rate review has saved consumers $6.6 billion since 2019 — a departmental figure, not an independently audited one.
The regulation also keeps California’s intervenor process, under which third parties who can show they represent consumers’ interests may be compensated. The Department’s release notes those fees are passed on to consumers in rates, and contrasts the new public rate range indications with intervenor negotiations it describes as previously conducted behind closed doors.
Why No Start Date Has Been Published
Neither the Department’s release nor the trade coverage gives an effective date, and the Department has not published the date the regulation was filed with the Secretary of State. Without that filing date the start cannot be stated, because California law ties the two together.
Under section 11343.4 of the California Government Code, an approved regulation takes effect on one of four quarterly dates according to when it is filed: 1 January for filings between 1 September and 30 November, 1 April for 1 December to the end of February, 1 July for 1 March to 31 May, and 1 October for 1 June to 31 August. An agency may specify a later date, and the Office of Administrative Law may grant an earlier one if the agency shows good cause.
So the regulation has been approved and its text published, but the day it begins to operate is not on the public record. California’s recent insurance legislation shows how much that matters: the nine insurance bills signed this autumn carry five different start dates between them.
What It Does Not Change for a California Homeowner
- Premiums: No rate goes up or down because of this regulation. It changes how a proposal is examined and what the public sees, not what any company charges.
- Non-renewals: The regulation addresses pricing, not an insurer’s decision to stop writing or renewing policies in an area.
- The FAIR Plan: California’s insurer of last resort is unaffected; its own average 29.1% rate increase proceeded separately.
- Market availability: Decisions such as State Farm’s cap on new policies sit outside the rate-approval process entirely.
The Department puts the statewide average homeowners premium at about $1,500 a year, citing data from the National Association of Insurance Commissioners. A statewide average is not what any individual household pays; premiums in California vary with location, wildfire exposure, construction, claims history and the insurer, and two neighbours can be quoted very different figures.
Frequently Asked Questions
Is the New California Insurance Rate Review Mandatory?
No. The Comprehensiveness Review Regulation creates a voluntary step an insurer may take before filing. A company that skips it files directly and is reviewed under the existing Proposition 103 process.
When Does the Regulation Take Effect?
No effective date has been published. The Office of Administrative Law approved it and the Department posted the final text on 19 October 2026, but the filing date that would fix the quarterly start date under California Government Code section 11343.4 is not on the public record.
What Will the Department Publish?
Its own analysis: the issues flagged in each submission, initial rate range indications, and predicted rate savings in dollars, on the California Department of Insurance website. The insurer’s underlying filing is not what is being opened up.
Does This Lower Home Insurance Premiums in California?
Not by itself. The regulation governs how a proposed rate is examined before a formal filing and what the public can see. Any change to a premium still comes through the Proposition 103 approval process.
Who Pays for the Intervenor Process?
Consumers do, through rates. The Department’s release states that third parties who show they represent consumers’ interests may be compensated through fees passed on to policyholders in rates.
