Workers’ Comp Class Code 5606: Construction Executives and Supervisors
Class code 5606 is the California classification for construction company leaders who run the business from above the crews: owners, officers and senior managers who do not directly supervise the trades. Its loss-cost figure is a fraction of the trade codes’, which is why auditors test it closely. Here is how the test works and how to keep the right people in it.
What class code 5606 covers in California
The class is written for contractors in construction or erection whose executive-level supervisors have no direct supervision of the work. The WCIRB’s September 1, 2026 filing adds plain language that the code applies to contractors, and that it can be assigned only together with the construction classifications listed in Appendix I of the Uniform Statistical Reporting Plan. The Department of Insurance notice describes that change as a clarification of how the class was always meant to apply.
Beyond owners and vice presidents, the code reaches management staff such as safety managers, project managers and engineers who walk job sites during construction without supervising the crews. They qualify when the company has the required layers of supervision below them, or when every bit of construction is handed to licensed subcontractors. Without either, those managers are treated as miscellaneous employees and go to the company’s governing class. Our California workers’ comp class code guide explains how a governing class is chosen.
The two-level supervision test
An executive belongs in 5606 only when at least two levels of supervision sit between that person and the workers doing the construction. The rules define those levels, and a first-level supervisor is generally the person running one crew, in one trade, at one site.
The test is easy to fail in a growing company. An owner who still runs a single crew, or who picks up tools when the schedule slips, is not above two layers of supervision, and an auditor will move that payroll into the trade the company performs. The second route into the code is a business where all construction is subcontracted to licensed contractors and the company develops no construction payroll of its own.
Neighbouring codes: 8742, 8601 and 5610
Several office-facing roles sit outside the class even when they visit sites. Estimators, outside salespeople and public relations staff are excluded, and employees who go to a project only for pre-construction estimating or client meetings, with no supervisory or inspection role, belong in 8742, outside salespersons. A firm that manages construction for a fee but neither performs nor supervises the work is classified as 8601(1), the engineering class.
On a project where everything is subcontracted, the company’s other employees who clean up the site, haul debris or handle warranty repairs are reported in 5610, the class for contractors whose construction is all subcontracted. It sits well above 5606 in loss cost, so it matters that those workers are listed in it rather than left in the executive line.
Reporting executive payroll, with no split
The class title itself says that a single employee’s payroll cannot be divided between 5606 and any other classification. A project manager who spends Mondays directing a framing crew and the rest of the week in meetings cannot be given a partial executive allocation. Directly supervising the crew takes the role out of 5606, and all of that person’s pay is reported in another class.
Owners and officers who elect coverage are rated on their actual pay within limits. Under the September 1, 2026 filing, covered executive officers, partners, individual employers and LLC members are reported at no less than $66,300 and no more than $171,600 a year. If you are deciding whether to cover yourself at all, our guide for sole proprietors covers the owner side.
Checking your code before an auditor does
Your insurer assigns codes when the policy is issued and confirms them at the premium audit, so the declarations page and the audit report are where to read what you have now. Keep an organisation chart that shows each supervision level and a short duty list for every person in 5606.
If you think a class is wrong, the WCIRB takes a written inquiry from the employer, naming the policyholder, the insurer and the reason. It has to reach the WCIRB within 12 months after the policy expires. A decision you disagree with can then go to a formal complaint, then a request for reconsideration or an appeal to the Insurance Commissioner.
What 5606 means for your premium
The WCIRB’s advisory pure premium rates effective September 1, 2026 put 5606 at 0.842 per $100 of payroll, against 3.624 for 5610 and 12.075 for low-wage carpentry in 5403. These are loss-cost benchmarks the Insurance Commissioner approved, not prices: insurers are not bound by them and add their own expenses, credits and your experience modification.
When we request workers’ compensation quotes for a builder, we look for a clear duty description for each executive so the insurer can decide the class from the file. Our contractor insurance page covers the policies that sit alongside it.
A few useful answers
Common questions
Can a small contractor use class code 5606 for the owner?
Only if there are at least two levels of supervision between the owner and the people building, or the company subcontracts all construction to licensed contractors and has no construction payroll. An owner who leads a crew directly is classified with the trade.
Is an estimator classified in 5606 or 8742?
Estimators are excluded from 5606. An estimator who visits sites only for pre-construction estimating or client meetings, with no supervisory or inspection duties, is reported in 8742.
Can one manager’s pay be split between 5606 and a trade code?
No. The 5606 class does not allow a single employee’s payroll to be divided with any other classification, so the person’s duties decide one class for all of their pay.
Can I get workers’ comp for my construction executives through Mithril1?
It can, when an insurer accepts the risk after reviewing your payroll, supervision structure and claims history. We request quotes with each role described, and the insurer decides the classes and the price.
