California policyholders should first check whether their policy names GuideOne Insurance Company or GuideOne Specialty Insurance Company and whether it belongs to the Commercial Niche program. Then request the relevant filing record and ask the California Department of Insurance, or CDI, about applicable public-participation procedures. CDI's October 23, 2026, notice lists an overall rate request of 18% for each company's commercial multi-peril entry. Those entries do not establish an approved increase, an implementation date, or what any individual policyholder will pay. The immediate task is to identify the relevant record before drawing conclusions about a renewal. Source: CDI, October 23 rate-filings workbook.

Identify the insurer and program in the notice

CDI's undated public-notices index, checked October 29, 2026, labels the selected workbook October 23, 2026. That is the verified notice date. It should not be substituted for an application submission date, approval date, or policy effective date. Those other dates have not been verified for the GuideOne entries. Source: CDI, Public Notices of Rate Filings.

The workbook identifies the records as follows:

  • GuideOne Insurance Company: CDI file 26-1847, commercial multi-peril, filing type RATE, Commercial Niche program, overall rate request 18%.
  • GuideOne Specialty Insurance Company: CDI file 26-1847-A, the same listed line, filing type and program, with an overall rate request of 18%.

Both entries carry SERFF filing number GDEA-135097156. Preserve the complete legal names and both CDI identifiers when requesting information; the shared SERFF number does not erase the separate insurer entries. These details come from the original notice, rather than an estimate of customer prices. Source: CDI, October 23, 2026, workbook.

The workbook totals 74 applications across several filing types. That number is neither a count of affected policyholders nor a count of rate increases. The GuideOne rows themselves provide no policy count. They also do not identify all GuideOne customers as affected, so a brand name alone is insufficient to connect a particular policy with this program. Source: CDI, October 23 workbook.

Request the record using the filing numbers

CDI's undated public-notice cover letter, checked October 29, describes access to submitted filings through its Virtual Viewing Room. It gives ViewingRoom@insurance.ca.gov for access assistance and identifies the Rate Enforcement Bureau at 1901 Harrison Street, Oakland, CA 94612. Its Public Advisor contact for participation information is (916) 492-3559. These are contacts in the general notice, rather than confirmation of a GuideOne hearing. Source: CDI, Public Notice of Insurance Companies Rate Filing.

A useful records request should name the legal insurer, CDI file number and shared SERFF identifier. Ask for the application, any amendments or replacement notices, the current disposition, any decision or order, and any implementation dates. Asking for those documents does not imply that an order or amendment exists. It identifies the information needed to move beyond the summary rows.

For your own records, keep the notice and the department's response together. If someone attributes a renewal change to these filings, ask which document connects your policy to the named program and which record establishes the applicable rate and date. This is a practical verification step drawn from the notice's limited contents and CDI's filing-access guidance. Sources: CDI workbook and public-notice cover letter. Filing-access guidance.

Ask CDI which participation procedure applies

The standard cover letter identifies Insurance Code section 1861.05 and describes written hearing requests within 45 days of a notice. Because it is general guidance, a reader should ask CDI which notice and procedure apply to the specific file before relying on a calendar deadline. This report does not calculate a deadline from the October 23 listing. Source: CDI, undated public-notice cover letter.

CDI's November 25, 2024, Bulletin 2024-14 supplies additional context. It addresses admitted property and casualty insurers subject to Proposition 103, explains prior approval, and says commercial rate changes exceeding 15% may require a hearing upon timely request. The bulletin also discusses successive applications and renewed notice after amendments. These qualifications matter when asking the department about participation. Source: CDI, Bulletin 2024-14.

The listed GuideOne requests exceed that stated percentage threshold. That comparison is a reason to seek filing-specific instructions; it does not establish that a hearing has been requested, is required in these particular files, or has been scheduled. The current original statutory text, program-specific exceptions and current case records were not verified. The legal context here is therefore attributed to CDI's documents, without a conclusion about every rule governing these applications. Sources: CDI's listed requests. CDI's conditional hearing guidance.

Ask the Public Advisor how to submit a written request, what information it should contain, and how to confirm the applicable trigger and deadline. Keep a copy of the instructions and any submission. This recommendation follows CDI's participation guidance; it is not a finding that an individual reader qualifies for a particular procedural outcome.

Raise eligible pricing options at renewal

The same November 25 bulletin says insurers within its stated scope must offer eligible coverage and pricing options on application and renewal. A policyholder can use that guidance to frame a specific question: which current options does this policy qualify for, and how has the insurer addressed those options in the renewal proposal? Source: CDI, Bulletin 2024-14.

Request an explanation tied to the actual policy rather than assuming that a public rate request answers the eligibility question. Nothing in the verified notice establishes an individual policy's eligibility, a missed offer, a discount, or a saving. The bulletin provides a basis for asking about options within its scope; it does not demonstrate a GuideOne violation or promise a lower premium.

For a business planning its next insurance payment, the useful distinction is between a question to investigate and a price established by policy documents. Keep the renewal proposal available when seeking answers so that the discussion concerns the coverage and pricing actually being offered.

Separate a company request from a customer bill

InsuranceHikes' undated California explainer, checked October 29, makes the same basic distinction: company rate requests are not individual customer bills, and requests are separate from state decisions. That independently published explanation can help a reader interpret a filing percentage without converting it into a personal price forecast. Source: InsuranceHikes, Insurance rate changes in California.

Its role here is limited consumer context. The page's stated data coverage ends September 30, 2026, before the selected GuideOne notice. It is not independent confirmation of these October entries. Nor does this report use its statewide aggregates to estimate a GuideOne customer's outcome. The evidence for the selected requests remains CDI's original workbook.

Accordingly, do not apply the listed percentage to your present payment and treat the result as an established renewal charge. An individual premium effect and any approved percentage remain unverified. Seek the actual renewal terms and the relevant decision record instead of filling those gaps with arithmetic.

Keep the unanswered questions attached to the news

As of the October 29 evidence check, the GuideOne applications' submission dates, amendments, disposition and implementation dates had not been verified. The notice supports reporting that the requests were listed; it does not establish that they are currently pending, approved or denied. The affected policy population, individual dollar effects and insurer rationale also remain unknown. Source: CDI, October 23 notice, whose GuideOne rows do not supply those details.

For policyholders, the next useful information is specific: whether the named insurer and Commercial Niche program match the policy, what the full case record says, and which participation instructions CDI confirms. Those answers serve different purposes. The policy match establishes relevance, the record establishes what happened after the notice, and the department's instructions identify the procedure a reader can follow.

Gather your policy and renewal documents, match the insurer and program, and ask CDI for the filing record and applicable participation instructions before treating a requested rate as your premium.
