Workers' Comp Insurance in San Jose, CA

Updated October 27, 2026

Workers' comp insurance in San Jose is mandatory from your first hire. Every California employer except the state has to secure the payment of compensation (Labor Code §3700), which in practice means buying a workers' compensation policy from an authorized insurer. Insurance City San Jose, at 25 N 14th St, Ste 125, quotes workers' comp for Santa Clara County employers with several carriers: tell us what your people do and what you pay them, and we come back with the options that fit your class.

Does a San Jose business with one employee need workers' comp?

Yes. The California Department of Industrial Relations tells employers they are required by law to have workers' compensation insurance "even if they have only one employee." That covers the first hire at a startup, a single cook or dishwasher, a part-time bookkeeper or a seasonal landscaping helper. The statute itself, Labor Code §3700, allows two routes: insurance from a carrier authorized in California, or a certificate of consent to self-insure issued by the Director of Industrial Relations.

If you are a sole owner with nobody on payroll, §3700 does not reach you, unless you hold one of the contractor licenses that must carry coverage anyway (see the contractor section below).

Why payroll matters so much for a San Jose premium

Workers' comp is priced on payroll. The WCIRB (the Workers' Compensation Insurance Rating Bureau of California) explains that the premium "begins with multiplying the insurer's premium rate for the employer's assigned classification(s) by the payroll," and that rates are applied per $100 of payroll. Because the class rate is multiplied by every $100 you pay, two businesses in the same class code pay in proportion to their payroll: the business paying higher wages pays more premium, all else equal.

Piece of the formula	Where it comes from	What you send us
Class code rate	The rate the insurer filed for the WCIRB classification that matches the work	A plain description of each group's duties
Payroll ÷ 100	Your estimated payroll in each class, checked at the year-end audit	Payroll by group for the next 12 months
Experience mod	WCIRB, only if your business meets the experience-rating eligibility threshold	Loss runs and years in business

For a sense of the math only, the WCIRB's own illustration is a rate of $5.86 per $100 of payroll. At that illustrative rate, a $500,000 payroll works out to $29,300 before any experience mod ($500,000 ÷ 100 × $5.86). That is arithmetic on WCIRB's example, not a rate for any class code and not a quote.

The experience mod is a percentage. In the WCIRB's explanation, under 100% means better-than-average claims history and usually a lower premium; over 100% usually means a higher one. Not every business qualifies: experience rating is mandatory only once a business meets the WCIRB eligibility threshold, so many small and new employers have no mod at all.

What are the penalties for an uninsured employer in San Jose?

California treats a missing policy as a misdemeanor. Labor Code §3700.5 provides for up to one year in county jail, a fine of up to twice the premium you should have paid while uninsured with a floor of $10,000, or both; on a second or later conviction the fine is triple the premium, with a floor of $50,000. The state does not wait for a court: under §3710.1 the Director serves a stop order that bars you from using employee labor until you comply, and §3722(a) adds a penalty of $1,500 for each employee working when the order is served. (Statute text read on leginfo.legislature.ca.gov, October 27, 2026.)

Do San Jose contractors need workers' comp with no employees?

For five license classes, yes, today. The Contractors State License Board lists C-8 Concrete, C-20 Warm-Air Heating, Ventilating and Air-Conditioning, C-22 Asbestos Abatement, C-39 Roofing and C-61/D-49 Tree Service as classes that must carry workers' comp, or a valid self-insurance certificate, whether or not they have employees. SB 216 added C-8, C-20, C-22 and D-49 effective January 1, 2023 (CSLB bulletin #22-16); roofing was already covered.

For every other license class, the deadline is January 1, 2028. SB 1455 (Chapter 485, Statutes of 2024) replaced SB 216's 2026 date, and the version of B&P Code §7125 operative on that date exempts only joint ventures without employees. A B general or electrical contractor on a no-employee exemption should budget for a policy before then.

Frequently asked questions

Is workers' comp required for a San Jose startup with one employee?

Yes. California requires workers' compensation from the first employee (Labor Code §3700; Department of Industrial Relations). The policy should be in force before the employee's first day.

How is workers' comp premium calculated for a San Jose business?

According to the WCIRB, the insurer's rate for your class code is applied to every $100 of payroll in that class, then adjusted by your experience mod if you have one, plus the insurer's other filed factors. Higher payroll in the same class means proportionally higher premium.

What is an experience mod, and will my business have one?

According to the WCIRB, it compares your claims with similar employers. Under 100% usually lowers premium, over 100% raises it. Smaller and newer businesses often have no mod until they meet the WCIRB eligibility threshold.

When do all California contractors need workers' comp?

January 1, 2028, under SB 1455. Until then, C-8, C-20, C-22, C-39 and C-61/D-49 licensees already need it with or without employees (CSLB).
