California Construction Insurance

Yes. Altamira Insurance Agency is an independent commercial insurance brokerage that specializes in California contractors. We are licensed in California (CA License No. 6017420) and place coverage with multiple top-rated carriers admitted in California, including markets that specifically write contractor risks. Although our office is in St. George, Utah, a substantial portion of our book is California construction business across Los Angeles, Orange County, San Diego, the Bay Area, Sacramento, and the Inland Empire.

The California Contractors State License Board (CSLB) requires every licensed contractor to maintain (1) a $25,000 Contractor License Bond at all times, and (2) workers compensation insurance if you have employees, even part-time. If a non-owner Responsible Managing Officer (RMO) or Responsible Managing Employee (RME) qualifies your license, an additional $12,500 Bond of Qualifying Individual is required. General liability insurance is not required by the CSLB itself, but virtually every general contractor, property owner, public agency, and commercial client in California requires proof of GL before allowing you on a job site.

Most small-to-mid California contractors pay between $800 and $4,000 per year for $1M/$2M general liability, depending on trade, revenue, and claims history. Higher-risk trades (roofing, demolition, foundation work) and contractors doing larger commercial or public works projects pay more. California typically runs higher than Nevada, Utah, Arizona, or Texas because of state litigation costs, labor laws, and Prop 213-style exposure. Altamira shops multiple carriers to find the most competitive rate for your specific class code and revenue.

In California, workers compensation premium is multiplied by your experience modifier — the X-mod — which is calculated by the WCIRB (Workers Compensation Insurance Rating Bureau of California) based on your three-year claims history. A 1.0 X-mod is industry average; below 1.0 saves you money, above 1.0 costs you. California is unusually X-mod sensitive because of high benefit costs and long claim tails. Altamira reviews every California workers comp renewal for X-mod accuracy and helps clients implement safety programs that lower the X-mod over time.

Yes. We work with surplus lines and specialty markets that are comfortable with California construction risks other carriers decline. That includes roofing contractors, demolition contractors, fire and water damage restoration, structural steel, foundation and shoring, and contractors with a prior loss. If you have been declined elsewhere, ask us — we frequently place California contractors that captive agents and direct carriers cannot.

Wildfire is a property-side concern more than a liability concern. If you carry builders risk or installation floater coverage on a project in a designated California wildfire zone, the underwriter will evaluate fire exposure and may apply additional premium or restrictions. Altamira places builders risk through markets that write CA wildfire-zone projects, including in Sonoma, Napa, Riverside, San Bernardino, and Santa Cruz counties.

Yes — for qualifying owner-controlled or contractor-controlled insurance programs we partner with specialty wrap-up markets. OCIP/CCIP placements typically apply to projects of $25M+ in construction value, multi-prime jobs, or owner mandates on public works. Contact us with project specifics and we will route to the appropriate market.

We write California contractors statewide. The areas we serve most often include Los Angeles County, Orange County, San Diego County, San Bernardino County, Riverside County, Ventura County, Santa Barbara County, Kern County, the San Francisco Bay Area (San Francisco, San Mateo, Santa Clara, Alameda, Contra Costa, Marin), Sacramento and the greater Sacramento Valley, Fresno, Bakersfield, and the Central Coast.

California habitational and multi-family is a difficult market, but we have access to carriers that write it. We can place general liability, workers comp, and excess/umbrella for general contractors and subs working on apartment construction, condominium projects, and renovation of habitational properties. Tell us the scope and we will identify the right markets.

Most California contractor quotes are returned the same business day, often within an hour for standard placements. Once bound, certificates of insurance are issued the same day — including additional insured endorsements and waiver of subrogation language required by California GCs and property owners.
