California Contractor Insurance Requirements (2026 Rules)

Short answer: California moved the line on January 1, 2026. Business and Professions Code section 7125 now requires every CSLB-licensed contractor to carry workers’ compensation insurance or a Certification of Self-Insurance — regardless of classification, and regardless of whether you employ anyone. The exemptions left in the statute are a joint venture with no employees, and a license you keep inactive. Separately, every California license needs a $25,000 contractor’s bond. There is no state home warranty fund.

This is the biggest change California contractors have seen in this area in a decade, and it is recent enough that much published advice still describes the old rule. The statute is administered by the Contractors State License Board, under the Department of Consumer Affairs; tax runs separately through the IRS and the Franchise Tax Board. If you are still at the licensing stage, read California contractor license requirements first. And if your structure is not settled, the rules below give California-specific reasons to think hard about whether you need an LLC.

Is workers’ compensation insurance mandatory for California contractors?

As of January 1, 2026, yes — for essentially everyone holding an active license.

Senate Bill 216 rewrote Business and Professions Code section 7125 and phased the requirement in. Roofers (C-39) went first. From July 1, 2023 it extended to C-8 Concrete, C-20 Warm-Air Heating, Ventilating and Air-Conditioning, C-22 Asbestos Abatement and D-49 Tree Service. Then the general rule landed.

Date	Who must carry workers’ comp regardless of employees
Before July 2023	C-39 Roofing
From July 1, 2023	C-8, C-20, C-22, D-49 added
From January 1, 2026	All classifications

Section 7125 states plainly that it “shall become operative on January 1, 2026,” and requires applicants and licensees to hold a current and valid Certificate of Workers’ Compensation Insurance or Certification of Self-Insurance as a condition of issuance, renewal and maintenance of an active license.

One caveat. CSLB’s older exemption pages still describe the narrower rule and still list only C-8, C-20, C-22, C-39 and C-61/D-49 as classifications that cannot be exempt. The statute is broader. Before relying on an exemption for any classification, confirm your position directly with CSLB rather than a cached web page — including a page on CSLB’s own site.

Can a sole owner with no employees still claim an exemption?

This is where the change bites hardest, because the answer used to be a straightforward yes for most classifications.

Under the historical rule a sole owner could file a signed certification that they employed nobody in a manner subject to California workers’ compensation law. Under section 7125 as it now reads, the exemptions preserved in the statute are a joint venture organized under section 7029 that employs nobody, and a license held inactive for the period it stays inactive. A one-person C-10 or B license working jobs is neither.

Two older disqualifiers still sit on top of that, and CSLB states both: you cannot file an exemption if your license is qualified by a Responsible Managing Employee, and you cannot file one in the C-8, C-20, C-22, C-39 or C-61/D-49 classifications. If you do hold an exemption and later hire, proof of coverage must reach CSLB headquarters within 90 days of the hire.

The instruction for 2026: do not assume the exemption you filed in 2022 is still doing anything. CSLB’s own language is that coverage “must be continuous,” that failure to maintain it “will result in the license being suspended,” and that work performed while suspended counts as unlicensed. Filing an exemption that is not true is separately expensive — Business and Professions Code section 7125.4 sets a minimum civil penalty of $10,000 per violation for a sole owner and $20,000 for a partnership, corporation or LLC.

What bond does a California contractor license require?

Every active California license needs a $25,000 contractor’s bond filed with CSLB. That amount took effect January 1, 2023 under SB 607 — if you last looked before 2023, the figure you remember is lower. Two more bonds show up depending on how the license is structured:

Bond	Amount	When it applies
Contractor’s bond	$25,000	Every active license
Bond of Qualifying Individual	$25,000	Qualifier is not the proprietor, a general partner or a joint licensee — waived if an RMO certifies 10% or more of voting stock, or an LLC qualifier 10% or more of membership interest
Disciplinary bond	$25,000 to $250,000	Set by the Registrar; the floor is $25,000 and the ceiling is ten times the contractor’s bond. Held at least two years

A bond is not insurance, and both homeowners and contractors get this wrong. It does not protect you: it pays a claimant — a homeowner, an employee, a supplier — and the surety then comes after you for every dollar. Twenty-five thousand dollars is also the entire consumer backstop attached to a California license, small against a typical remodel.

Do LLC contractors need liability insurance in California?

Yes, and this is the one insurance requirement California genuinely imposes as a condition of licensure — but only on LLCs.

Business and Professions Code section 7071.19 requires an LLC contractor licensee to carry liability insurance with an aggregate limit of not less than $1,000,000 for a company with five or fewer personnel of record, plus an additional $100,000 for each additional person, capped at $5,000,000 in any one designated period.

An LLC license also requires a separate $100,000 surety bond for the benefit of workers under section 7071.6.5, covering damages from failure to pay wages, interest or fringe benefits — and, where a collective bargaining agreement applies, welfare, pension and apprenticeship contributions.

Stack it up and the California LLC route carries a cost a sole proprietorship or corporation does not: $1M+ in mandated liability cover and an extra $100,000 bond, on top of the $25,000 contractor’s bond everyone files.

Is general liability insurance required for a CSLB license?

For sole proprietorships, partnerships and corporations, no — CSLB does not condition the license on general liability cover. The mandate in section 7071.19 is specific to LLCs.

Commercially it is different. General contractors will not add you to a job without a certificate naming them as additional insured, and property managers and HOAs treat it as a threshold question. California requires it of LLCs by statute and of everyone else by market pressure.

Does California require home warranty insurance?

There is no state-run home warranty or building compensation fund in California. Australia and Canada both operate schemes where a builder buys per-project consumer protection before starting work; California does not. What exists instead is the $25,000 license bond, CSLB’s complaint and arbitration process, and the statutory construction defect regime. Any “home warranty” product you are asked to buy in California is a private contract, not a licensing requirement.

What if you work under the $1,000 exemption?

California’s minor work exemption in Business and Professions Code section 7048 covers a job where the aggregate contract price for labor, materials and all other items is less than $1,000 — but four conditions must all hold at once:

1. The work is casual, minor or inconsequential and does not require a building permit.
2. It is not part of a larger project, and contracts have not been split to get under the number.
3. You do not advertise or hold yourself out as a contractor.
4. You do not employ anyone to perform or assist with the work.

Read that list honestly. Anyone with a truck sign, a Google Business listing or a “licensed and insured” line in their ad has failed condition three. The exemption is narrower than the dollar figure makes it sound. Unlicensed contracting under section 7028 is a misdemeanor in California, and a first conviction carries a fine of up to $5,000, up to six months in county jail, or both.

What records prove you carried cover?

Every requirement here is proved by a dated document: the certificate of workers’ compensation on file at CSLB, the bond, the LLC liability policy, and the contracts and invoices showing what each job was worth against the $1,000 line.

That last category is the one that goes missing. Aggregate contract price includes labor, materials and everything else, so your invoices and supplier receipts are the evidence — and the same records feed how much to set aside for 1099 taxes.

Keel is built for that trail: PDF invoices with your own numbering, logo and a payment-link QR code, receipt capture read on-device with Apple Intelligence, a mileage log, reports, an Accountant Pack, an append-only hash-chained ledger, and a single-file export for the year. It runs entirely on the iPhone — no account, no bank connection, no cloud, App Store privacy label “Data Not Collected.” Free covers unlimited invoices, receipts and mileage; Keel Pro is a one-time $249.99 lifetime purchase.

Keel is a record keeper, not a compliance tool. It does not file CSLB paperwork, buy workers’ comp or post a bond. It keeps the evidence retrievable when CSLB, an insurer or your CPA asks — the same job a contractor receipt organizer does.

Frequently asked questions

I have no employees. Do I really need workers’ comp in California in 2026?

Under section 7125 as it became operative on January 1, 2026, the requirement applies to all licensed contractors regardless of classification, and the exemptions preserved in the statute are a joint venture with no employees and a license kept inactive. Some CSLB pages still describe the older, narrower rule. Confirm your license status with CSLB directly before assuming an exemption stands.

How much is the California contractor bond and is it insurance?

It is $25,000, effective since January 1, 2023 under SB 607, and it is not insurance. A bond pays a claimant and the surety then recovers the full amount from you. Your annual premium buys the guarantee, not coverage. If you want protection for your own business, that is what general liability and workers’ compensation do.

Does an LLC contractor license cost more to insure in California?

Yes, measurably. An LLC must carry liability insurance of at least $1,000,000 aggregate for five or fewer personnel, rising $100,000 per additional person to a $5,000,000 cap, plus a separate $100,000 worker bond — on top of the standard $25,000 contractor’s bond. Sole proprietorships and corporations have no equivalent statutory requirement.

Can I work under $1,000 in California without a license?

Only if all four conditions in section 7048 hold: the work is casual, minor or inconsequential and needs no building permit; it is not part of a larger operation or a contract split to get under the number; you do not advertise or hold yourself out as a contractor; and you employ nobody to perform or assist. Advertising alone disqualifies you however small the job, so a truck sign or a Google listing ends the argument before the price does.

What happens if I hire someone while my exemption is on file?

The exemption stops being valid immediately, and proof of workers’ compensation coverage must reach CSLB headquarters within 90 days of the hire. CSLB’s position is that coverage must be continuous and that failing to maintain it will result in the license being suspended — and any work performed while suspended is treated as unlicensed, which is a far worse outcome than a late-filing penalty.

Who do I ask when the rules conflict?

CSLB, directly. This area changed on January 1, 2026 and not every published page — including some on CSLB’s own site — has caught up. For coverage questions rather than licensing ones, the Department of Industrial Relations is the state authority. For tax, the IRS and the Franchise Tax Board.
