General Contractor Insurance in San Diego: Getting the CSLB Workers’ Comp Rules Right
San Diego general contractor insurance conversations in 2026 keep starting from the same confused headline. For years, contractors heard one message. Every CSLB licensee would need workers’ compensation by January 1, 2026, employees or not. That deadline moved. Follow-up legislation pushed the universal requirement to January 1, 2028. Meanwhile, five classifications stay on the mandatory list right now. Getting this wrong costs money in either direction. Some contractors buy coverage years before the state requires it. Others file an exemption they no longer qualify for and lose their license mid-project.
Where the Comp Rules Actually Stand
Per the CSLB workers’ compensation requirements, every licensee files one of two documents. The first option is a valid certificate of insurance. The second is a signed exemption certifying no employees. Five trades have no exemption path: concrete (C-8), HVAC (C-20), asbestos abatement (C-22), roofing (C-39), and tree service (D-49). Those contractors carry coverage whether or not they have employees. The exemption also dies if a Responsible Managing Employee qualifies your license. Hire anyone, and the exemption ends immediately. CSLB then expects proof of coverage within 90 days. A lapse suspends the license, and the state treats work performed during a suspension as unlicensed work.
For a B General Building contractor, the practical read is simple. The exemption path still exists until 2028 if you truly have no employees. Your subs in the mandatory trades should already carry comp regardless of crew size. Check for it when you collect their certificates.
San Diego General Contractor Insurance: The Rest of the Stack
Every California contractor posts a $25,000 license bond. Run the business as an LLC and the state adds more. LLCs post a $100,000 employee/worker bond and carry at least $1 million in liability coverage. Beyond the licensing minimums, think about your project mix. San Diego’s steady diet of ADU work, remodels, and coastal rebuilds gives completed operations exposure a long life. Our general contractor insurance guide walks through the endorsement stack that protects a GC there. Get additional insured status for ongoing and completed operations from every sub. Add primary and noncontributory wording. Keep a certificate file that survives your audit.
Verify Your Subs the Same Way Owners Verify You
California hands GCs a free verification tool most states lack. CSLB’s public license check shows each contractor’s license status, bond on file, and workers’ comp coverage, including the carrier and policy dates. Run every sub through it before mobilization, especially subs in the five mandatory comp trades. The lookup takes a minute. It catches the lapsed policy that a months-old certificate never would, and it documents your diligence if a claim later asks what you knew. Pair the lookup with the endorsements themselves and your file holds up on both fronts.
A Hard Market Rewards a Clean File
California’s property and casualty market has run tight for several years, and construction risks feel it first. Underwriters in this state price the discipline they can see. That means documented risk transfer, verified sub coverage, and clean loss runs. When we market a San Diego GC account, we package that file deliberately. It moves quotes more than any single coverage tweak.
