Employment Law for Construction Workers in California
Construction workers build California — its homes, its offices, its infrastructure. They are also among the most frequently misclassified, underpaid, and retaliated against workers in the state. California law provides specific protections for this workforce, and the violations are as predictable as the industry that produces them.
The construction industry in California employs roughly one million workers and generates tens of billions in revenue. It is also an industry with structural characteristics that produce systemic employment violations: layered subcontracting that obscures who is responsible for the workforce; widespread misclassification of employees as independent contractors; physically dangerous conditions that create pressure not to report injuries; and a mobile workforce that makes enforcement difficult.
California has responded with protections that address each of these characteristics — and the violations remain common not because the law is unclear but because the industry’s structure makes compliance optional for employers who calculate that the cost of noncompliance is lower than the cost of compliance.
Misclassification
Independent contractor misclassification is the defining employment law issue in California construction. Employers classify workers as independent contractors to avoid payroll taxes, workers’ compensation premiums, overtime obligations, and benefit costs. The workers perform the same tasks, at the same sites, under the same supervision as employees — but they are paid on a 1099, receive no benefits, and are told they have no employment rights.
The ABC test under Dynamex and Labor Code section 2775 applies to most construction workers, with specific exceptions. Prong B — whether the work is “outside the usual course of the hiring entity’s business” — is the critical question. A framing subcontractor that hires framers is performing work within its usual course of business. The workers are presumptively employees.
The construction industry has a specific exemption from the ABC test for certain licensed subcontractors who meet defined criteria — including holding a valid contractor’s license, maintaining a business location, having the ability to set their own rates, and customarily performing work for multiple clients. But the exemption is narrow, and many arrangements that employers treat as qualifying do not.
A construction worker who is classified as an independent contractor but who works exclusively for one general contractor, follows the contractor’s schedule, uses the contractor’s equipment, and has no independent business presence is almost certainly an employee — and is owed all the protections the classification was intended to deny.
Prevailing wage
On public works projects — construction funded by public money — contractors and subcontractors must pay their workers the “prevailing wage,” which is the rate determined by the Department of Industrial Relations to be the standard in the geographic area for the specific trade.
Prevailing wage rates are significantly higher than private-sector rates and include requirements for fringe benefits — health insurance, retirement contributions, vacation pay — that the contractor must either provide directly or pay as an additional hourly amount.
Prevailing wage violations are common. Contractors pay the base rate but not the fringe benefits. They misclassify workers in lower-paying trades to reduce the applicable rate. They fail to maintain accurate records of hours worked. Each of these is a violation with specific penalties — including up to twice the difference between the amount paid and the prevailing wage, plus interest.
Workers on public works projects should know the applicable prevailing wage rate for their trade and should compare it to their actual compensation. The DIR publishes the rates, and they are available online.
Safety and Cal/OSHA
Construction is the most dangerous industry in California. Falls, struck-by incidents, electrocutions, and trench collapses account for the majority of construction fatalities. Cal/OSHA’s construction safety standards are among the most detailed in the state, addressing fall protection, scaffolding, excavation, electrical work, and dozens of other hazards.
An employer that fails to comply with Cal/OSHA construction standards — that does not provide fall protection at heights above six feet, that does not shore trenches deeper than five feet, that does not provide required personal protective equipment — is violating the law. A worker who reports these violations is protected against retaliation under Labor Code section 6310.
The retaliation protection is critical because construction workers face intense pressure not to report safety hazards. The work is physically demanding, the labor market is competitive, and an employee who complains about safety may be replaced by someone who does not. The law’s response is to make the retaliation itself unlawful — and to provide remedies (reinstatement, back pay, penalties) that impose a cost on the employer that retaliates.
Joint employment and subcontractor liability
Construction projects involve layered subcontracting — a general contractor hires subcontractors, who hire sub-subcontractors, who hire the workers. When a violation occurs — unpaid wages, misclassification, safety hazards — the worker may not know which entity is responsible.
California law addresses this through joint employment principles and through Labor Code section 2810.3, which makes a client employer jointly liable with a labor contractor for wage violations and workplace safety. A general contractor that hires a subcontractor to provide workers may be jointly liable for the subcontractor’s failure to pay wages, provide workers’ compensation coverage, or maintain a safe workplace.
This means a construction worker who is not paid by the subcontractor may have a claim against the general contractor — and potentially against the project owner, depending on the circumstances. The layers of subcontracting do not insulate the entities at the top from the violations committed at the bottom.
Wage theft in construction
Construction wage theft takes specific forms.
Unpaid overtime. Construction schedules frequently involve long days and weekend work. A non-exempt construction worker who works ten-hour days is owed two hours of overtime per day — but many employers pay straight time for all hours, or pay cash “off the books” to avoid overtime obligations.
Unpaid travel time. A construction worker who is required to report to a designated location (a yard, a staging area) and then travel to the job site is performing compensable work during the travel. An employer that does not pay for this travel time is violating the law.
Tool and equipment charges. An employer that requires construction workers to purchase their own tools — and that does not reimburse the cost — is violating Labor Code section 2802. The cost of tools required to perform the job is a necessary business expense that the employer must bear.
Cash payments without records. Paying construction workers in cash — without pay stubs, without records of hours worked, without tax withholding — is a violation of multiple Labor Code provisions. The worker has no records to prove the hours worked or the wages paid, which makes future claims more difficult. But the employer’s failure to maintain records is itself a violation, and in the absence of employer records, the worker’s own testimony about hours worked is sufficient to establish the claim.
What construction workers should know
If you work in construction in California, you are entitled to the same minimum wage, overtime, meal break, rest break, and safety protections as every other worker in the state. If you are on a public works project, you are entitled to prevailing wage. If you are classified as an independent contractor, the classification may be wrong — and if it is, you are owed everything the classification denied you.
The construction industry’s structure — the subcontracting, the cash payments, the mobile workforce, the pressure not to complain — makes enforcement difficult. But the rights are real, the remedies are substantial, and the protections exist precisely because the industry’s structure creates the conditions that make violations possible.
If you work in construction and you are being underpaid, misclassified, denied overtime, or subjected to unsafe conditions — the law reaches you regardless of how many layers of subcontracting stand between you and the project owner. Your rights as a construction worker are the same as every other worker’s, with additional protections for prevailing wage and workplace safety that reflect the specific risks of the industry.
