Most California small businesses need three to five policies, and two of them are effectively mandatory: workers' comp (required by law from your first employee) and general liability (required by nearly every commercial lease and client contract). This guide maps the core stack, with the typical 2026 price ranges we see for Westside businesses.
Founded here in Santa Monica in 1992, we insure the neighborhood's restaurants, shops, studios, contractors, and professional firms — the ranges below come from that day-to-day work plus published industry averages.
The core coverage stack
- General liability (GL): third-party bodily injury, property damage, and advertising injury. Landlords and clients demand it. Typical small-business cost: $30–$80/month. See our GL service page.
- Business Owner's Policy (BOP): GL + your own property (contents, tenant improvements, inventory) + business interruption, bundled at a discount — usually the right first move for shops, offices and restaurants.
- Workers' comp: required by law; commonly $60–$100+/month for low-risk payrolls. Full details in our California workers' comp guide.
- Commercial auto: any vehicle used for business — deliveries, job sites, client visits. Personal auto policies exclude business use more often than owners realize.
- Professional liability / E&O: for advice-and-services businesses (consultants, designers, brokers, medical/wellness). Our professional liability page covers it.
- Cyber liability: if you store customer data or take cards online. Small-business cyber policies start around $40–$120/month and increasingly show up as a contract requirement.
- Umbrella: stacks $1M+ over your GL and auto limits when contracts demand higher limits than your base policies carry.
What your lease and contracts will require
Commercial leases in Santa Monica routinely require $1M/$2M GL limits, additional-insured status for the landlord, and certificates of insurance before you get keys. Client MSAs add workers' comp, commercial auto, and sometimes cyber or E&O. Two practical tips:
- Send us the insurance clause before you sign — matching coverage to an already-signed lease is the expensive order of operations
- Certificates are free and same-day from a broker; never let a COI request stall a deal
California specifics worth knowing
- Workers' comp is criminal to skip — see the penalties
- Contractors need the $25,000 CSLB bond plus trade-appropriate GL
- Restaurants: liquor liability if you pour, and check assault-and-battery sublimits
- Wildfire exposure now affects commercial property placement on the Westside too — older buildings and brush-adjacent locations should start renewals early
How much is business insurance for a small business in California?
A typical Westside shop or office: GL $30–$80/month, workers' comp $60–$100+/month once you have employees, BOP bundles often $70–$150/month. Industry, payroll, and location move these substantially.
Is general liability insurance required by law in California?
Not by statute — but your lease, your clients, and common sense require it. Workers' comp IS required by law from the first employee.
What insurance does an LLC need in California?
The LLC wrapper doesn't change insurance needs: GL for third-party claims, workers' comp if it has employees, commercial auto for business vehicles, E&O if it sells expertise. The LLC protects owners from business debts, not the business from claims.
Can I use my personal auto policy for business deliveries?
Usually not — personal policies commonly exclude delivery and business use. A claim denied on those grounds is a painful way to find out; commercial auto or a business-use endorsement fixes it cheaply.
What's a certificate of insurance (COI) and how do I get one fast?
A one-page proof of your coverages that landlords and clients request. Your broker issues them same-day at no charge — including additional-insured endorsements when contracts require them.
