California’s commercial insurance market has changed materially over the last two years, especially for businesses that own property, lease space in wildfire-exposed areas, belong to HOAs or condo associations, or rely heavily on workers’ compensation coverage. The biggest changes are not a single new law or one isolated filing. Instead, they are a combination of regulatory reform, FAIR Plan expansion, wildfire-related consumer protections, and cost pressure in core commercial lines. For California business owners, the practical takeaway is simple: coverage rules are shifting, options may improve in some segments, and compliance and pricing are becoming more complex at the same time.
One of the most important changes is California’s Sustainable Insurance Strategy, which is now affecting how insurers price and write both homeowners and commercial business in wildfire-distressed areas. In 2024, the California Department of Insurance announced that commercial insurers would be required to increase coverage by 5% in wildfire-distressed ZIP codes statewide, specifically to expand options for farms, wineries, homeowners associations, condo associations, and other businesses. The Department also tied new catastrophe-model and reinsurance flexibility to insurer commitments to write more business in underserved areas. In late 2024 and 2025, the Department said insurers using approved catastrophe models and reinsurance in rate filings would have to maintain or expand writings in wildfire-prone areas, with the broader goal of moving policyholders out of the FAIR Plan and back into the voluntary market.
For commercial property buyers, the second major development is the expansion of the California FAIR Plan. In March 2025, Commissioner Ricardo Lara approved an increase in FAIR Plan Division I commercial property limits to $20 million per building and a $100 million maximum per location. The Department framed that change as a response to the reality that HOAs, builders, affordable housing projects, farms, and businesses were being priced out of the traditional market or left without workable coverage options. In July 2025, the Department said the new “high-value” commercial FAIR Plan option had taken effect and would remain available temporarily through 2028 while broader market reforms play out. For businesses that had found prior FAIR Plan limits too low to be useful, that is a meaningful change.
A third recent change is the extension of wildfire-related non-renewal protections to more commercial policyholders. Beginning January 1, 2026, California’s Business Insurance Protection Act (SB 547) expanded the existing wildfire moratorium framework beyond residential property to include commercial policies, specifically including businesses, HOAs, condominiums, affordable housing units, nonprofits, and other covered entities. In plain English, that means wildfire emergency protections that used to be discussed mainly in the homeowners context now have more relevance for organizations and business property risks as well. For property owners and associations in fire-prone areas, that change matters because it can affect renewal rights after a declared emergency.
A fourth change affects claims handling, especially for commercial properties with smoke damage. In March 2025, the Department issued Bulletin 2025-7, addressed to property and casualty insurers handling smoke damage claims for residential and/or commercial properties in California wildfire areas. The bulletin states that recent court decisions do not mean smoke damage is never covered. It says coverage depends on the policy language and facts of the claim, and it reminds insurers that they must conduct a thorough, fair, and objective investigation. The Department also said it is not reasonable to deny a smoke damage claim without an appropriate investigation, and that if professional testing is warranted, the insurer is expected to contract for and pay for those services. For commercial property owners, especially those dealing with contamination concerns after nearby fires, that bulletin is a significant practical development.
A fifth change is more technical, but it matters for larger commercial accounts and the surplus lines market. In Bulletin 2025-10, issued May 28, 2025, the Department updated the inflation-adjusted thresholds for California’s “commercial insured” exemption. Effective January 1, 2025, the threshold values increased by 22.7%, raising the minimums to $29,179,483 in net worth, $72,948,708 in annual revenues, and $43,769,225 in annual budgeted expenditures. These thresholds are important because they help determine whether a business qualifies for certain nonadmitted insurance treatment and regulatory exemptions. Middle-market businesses that assumed they were above or below older thresholds should make sure their advisors are using the updated numbers.
There has also been an important compliance reminder for insurers and sophisticated commercial buyers. In Bulletin 2025-11, the Department warned insurers that negotiated or mutually agreed rates, retrospective rating plans, “Large Risk Alternative Rating Options,” and consent-to-rate arrangements may violate Proposition 103 if the specific rating factors or formulas have not been filed and approved. The bulletin specifically says insurers rating risks, including large commercial risks, using unfiled arrangements do so at the risk of violating the prior-approval law, and it directed insurers already using such arrangements to stop and submit compliant rate applications. That does not mean every bespoke commercial pricing structure is illegal, but it does mean carriers and brokers must be careful about how customized commercial pricing is built and documented in California.
Workers’ compensation has moved in the opposite direction from what many California employers had grown used to over the last decade. In July 2025, Commissioner Lara said the Department had adopted a new workers’ compensation claims cost benchmark and average advisory pure premium rate reflecting an 8.7% increase from the prior year, with an adopted advisory pure premium rate of $1.52 per $100 of payroll, effective September 1, 2025. The Department attributed the pressure to higher medical treatment and medical-legal costs, more projected cumulative trauma claims, and rising claims adjustment expenses. Because workers’ compensation is one of the most important recurring insurance costs for many employers, this is one of the most consequential recent commercial insurance changes even though it is not part of the property market crisis.
Put together, these developments point to a California commercial insurance market that is trying to become more functional without becoming simpler. Businesses may see better access in some high-risk property segments because of FAIR Plan changes and the Sustainable Insurance Strategy. At the same time, buyers should expect continued pricing pressure, more documentation requirements, and closer scrutiny of how policies are rated and claims are handled. That means 2026 is a good year for California business owners to review their property schedules, verify valuations, revisit smoke and wildfire-related language, confirm whether they qualify as a “commercial insured” under the new thresholds, and check workers’ compensation budgets against rising advisory costs. None of those steps guarantees lower premiums, but they do improve the odds of getting the right coverage on better terms in a fast-changing market.
