Contractor Insurance in California: Liability, Comp, Trucks and Tools

Current amounts are on the CSLB bond requirements page (opens in a new tab). For an LLC, CSLB says the liability policy must come from an insurer licensed in California or an eligible surplus line insurer.

• The deadline moved once. SB 1455 shifted the all-licensee requirement from January 1, 2026, to January 1, 2028. CSLB's March 2026 report asked the Legislature for a narrow exemption for some sole owners, so check cslb.ca.gov before you renew.
• Violations cost more now. SB 291, passed in 2025, significantly raised CSLB's penalties for workers' comp violations, such as claiming the exemption while you have employees.
• Lapses suspend licenses. If a required policy lapses, Business and Professions Code section 7125.2 suspends the license automatically.
• Unlicensed subs become your problem. Under Labor Code section 2750.5, someone doing work that needs a license without one is treated as an employee, and the hiring contractor can end up responsible for that sub's crew as well.

Your insurer or broker can file the certificate with CSLB online, and it then shows on your public license record with the carrier, policy number and dates. See workers' comp insurance in California for how payroll and class codes set the premium.

Say a supply line you installed in a Stevenson Ranch kitchen lets go three months later and soaks the cabinets and floors. The homeowner's water damage is the kind of loss completed operations coverage is for. Redoing your own faulty connection usually isn't.

California also makes you disclose it. Home improvement contracts must include a notice saying whether you carry commercial general liability insurance (Business and Professions Code section 7159), and section 7164 requires a written statement when you build a single-family home for an owner who plans to live in it. If you're insured, you list the insurer's name and phone number. Our general liability insurance page covers limits and policy types, and a business owner's policy can pair it with coverage for a shop or yard.

• Additional insured: an endorsement that extends your liability coverage to the GC or owner for claims arising from your work.
• Primary and noncontributory: wording that makes your policy respond before theirs.
• Waiver of subrogation: your insurer gives up the right to recover from them after paying a claim.
• Limits: per-occurrence and aggregate amounts written into the subcontract, sometimes higher than you carry today.

Public agencies ask too. The City of Santa Clarita's published encroachment permit requirements, which apply to work in the public right-of-way such as a driveway approach or a trench in the street, call for a copy of your contractor's license and a certificate of insurance with an endorsement naming the City as additional insured. Send us the GC's insurance exhibit or the permit checklist before you bid, and we'll show you what needs an endorsement.

The California Department of Insurance describes inland marine as property insurance for business property on the move and lists contractor's equipment floaters among the common types. NEXT sells tools and equipment coverage as an add-on to its general liability policy.

• List the big pieces. Compactors, generators and trailers are usually scheduled by serial number and value.
• Ask about overnight theft. Some policies set conditions for tools stolen from a vehicle, such as a locked box.
• Know the settlement. Replacement cost buys new; actual cash value subtracts depreciation.
• Rented equipment. A rental contract for a lift or excavator may make you responsible for it.

The California Highway Patrol's permit guidance uses a construction company's pickup and trailer as one of its own examples, so this isn't only a big-rig issue. Employees who run to the supply house in their own pickups are a separate exposure, covered by hired and non-owned auto. Our commercial auto insurance page explains both.
