How many California contractors say they have no employees

48.5% of the 228,727 California contractor licences in good standing on the state licence board's master list have a workers' compensation exemption on file: the licensee has certified that it has no employees. From 1 January 2028, the board says, every licensee will need workers' compensation insurance whether or not it has employees.

A licence can be perfectly valid and still carry no workers' compensation cover, because the law lets a contractor with no employees file an exemption instead. What that means for the person hiring is simple: if people other than the licensee turn up to do the work, ask who they are and whether they are covered. This page counts how many licences rely on the exemption, trade by trade.

The law

Who may claim the exemption, and until when

  • Under Business and Professions Code §7125, a licensee keeps on file a certificate of workers' compensation insurance, a certificate of self-insurance, or an exemption certifying that it has no employees. CSLB: “Failure to maintain workers' compensation insurance coverage will result in the license being suspended.”
  • Concrete (C-8), warm-air heating, ventilating and air-conditioning (C-20), asbestos abatement (C-22), roofing (C-39) and tree service (C-61/D-49) contractors must carry workers' compensation insurance whether or not they have employees.
  • SB 1455 (Chapter 485, Statutes of 2024) delayed the requirement for all licensees to hold workers' compensation insurance to 1 January 2028, and requires CSLB to set up a process for the exemption.

Read at CSLB, Workers' Compensation Requirements and CSLB's industry bulletin on SB 1455, 17 Sep 2026. This is a summary, not legal advice; the statute governs.

A licence holding one of these classes alongside others is counted here. The file records the exemption but not why it remains; CSLB's live license check is the authority for any one licence.

How this was computed

  1. Every row of CSLB's License Master file is loaded, from a copy downloaded in a browser from CSLB's data portal, and checked against its row count.
  2. “In good standing” means a primary status of CLEAR. Every other status on the list is a suspension of some kind, listed above.
  3. Coverage type is CSLB's own field. Classifications are split on the file's separator and written without the dash, so C-10 and C10 are one class.
WITH c AS (
  SELECT DISTINCT l.license_no, upper(replace(btrim(x), '-', '')) AS class, l.wc_coverage_type
  FROM vetting.contractor_licenses l, unnest(string_to_array(l.classifications, '|')) AS x
  WHERE l.primary_status = 'CLEAR' AND btrim(x) <> ''

Honest limits

What this does not tell you

  • An exemption is not wrongdoing. A contractor who works alone is entitled to it, and many do.
  • It is a snapshot. The newest record in the file is dated 13 Sep 2026. Licences change daily; check the one you are hiring on CSLB's live license check.
  • It counts licences, not people or businesses. A licence holding several classifications appears in each of their rows.
  • The file cannot say who actually works on a job, which is the fact that decides whether an exemption is being used properly.
  • It is not legal advice, and it is not a background check. CivicDelta does not assess any contractor.

The free contractor check shows a licence's classifications, bond and workers' comp record as CSLB lists them.

Questions

Questions people ask

Do California contractors have to carry workers' compensation insurance?

Licensees with employees must. A licensee with no employees may file an exemption instead, except concrete, HVAC, asbestos, roofing and tree-service contractors, who must carry it regardless. CSLB says that from 1 January 2028 all licensees must carry it, under SB 1455. See CSLB's requirements page.

How many California contractors claim a workers' comp exemption?

111,016 of the 228,727 licences in good standing on CSLB's License Master file (48.5%), in records updated to 13 Sep 2026.

What should I ask a contractor with an exemption?

Who will actually be on your site. An exemption certifies that the licensee has no employees; if other people do the work, ask whether they are covered. CSLB's live license check shows the coverage on file for any licence.
