What the Data Shows
Survey data collected from independent insurance agents across California in late 2025 reveals median monthly premiums for commercial general liability insurance by industry. The figures below reflect $1M per-occurrence / $2M aggregate policies for businesses with five or fewer employees and under $500,000 in annual revenue.
| Industry | Median Monthly Premium | YoY Change |
|---|---|---|
| Janitorial / Cleaning | $42 | +6% |
| Landscaping | $58 | +9% |
| General Contracting | $115 | +14% |
| Roofing | $188 | +17% |
| Electrical | $134 | +12% |
| Plumbing | $122 | +11% |
| Consulting / Professional Services | $34 | +4% |
| Retail (storefront) | $51 | +7% |
| Food Service | $67 | +8% |
| Personal Training / Fitness | $38 | +5% |
The headline: construction trades are seeing the steepest increases, consistent with the claim trends reported in the 2025 WCIRB data.
Why Premiums Are Rising in California
Three factors dominate the increase: higher claim severity (more expensive injuries and settlements), nuclear verdict exposure (large jury awards affecting reinsurance pricing), and the rising cost of defense. California trial lawyers have become more aggressive in pursuing general liability claims, and carriers are pricing that risk into premiums before a claim ever happens.
What Small Businesses Can Do to Control Costs
Shop at every renewal. The market for CGL insurance is competitive, and carriers update their appetite for specific industries frequently. A carrier that offered the best rate for a cleaning business two years ago may no longer be competitive today, while a different carrier has moved in on that market. Independent agents who have access to multiple carriers can run a market comparison in a few hours.
Improve your loss run. If you've had claims in the past three years, they're on your loss runs and affecting your rate. Carriers look at frequency as much as severity — three small claims is often treated worse than one larger claim. Implementing basic risk management practices (documented safety procedures, signed work authorizations, photo documentation on every job) can keep claims off your loss runs.
Adjust your deductible. Many CGL policies are available with a per-occurrence deductible of $500–$2,500. Taking a higher deductible in exchange for a lower premium can make sense for businesses with strong cash flow and clean claims history.
Bundle where it makes sense. A business owner's policy (BOP) combines general liability and commercial property. For businesses with premises exposure, a BOP is typically cheaper than buying the coverages separately.
Southeast LA County Context
In Southeast LA County — Santa Fe Springs, Norwalk, Downey, Bellflower, Cerritos, La Mirada, Whittier — the contractor and service business market is price-sensitive. Many businesses are owner-operated, margins are tight, and insurance feels like overhead until a claim happens. The data above reflects California medians; rates in specific zip codes within LA County can run 5–15% above the state median due to litigation frequency.
Getting three or more quotes at renewal is the single highest-ROI action most small business owners can take on their insurance costs.
