Privette Doctrine: Exceptions, Cal-OSHA, and Homeowner Protection

The Privette doctrine is a California rule that shields a property owner or general contractor from civil liability when an independent contractor’s employee is injured on the job. The California Supreme Court adopted it in 1993, and it remains one of the strongest defenses available to hirers in construction injury cases. Three narrow exceptions can defeat the protection, but each requires the injured worker to prove the hirer did something specific that contributed to the harm.

Where the Rule Comes From and Why It Exists

The California Supreme Court decided Privette v. Superior Court in 1993. The court held that when a contractor’s own failure to maintain safe working conditions causes an employee’s injury, the injured worker cannot pursue the hirer for damages beyond workers’ compensation. Allowing that extra recovery from a “nonnegligent party,” the court reasoned, “advances no societal interest that is not already served by the workers’ compensation system.”¹

The reasoning is practical. When you hire a roofing company, an electrical contractor, or a demolition crew, you’re paying for their expertise. You’re not supervising them swing by swing. The law assumes the contractor knows their trade better than you do and is in the best position to keep their own workers safe. By handing the work over, you also hand over the safety responsibility that comes with it.

Before Privette, California followed a “peculiar risk” doctrine that let a contractor’s injured employees sue the hirer when the hired work involved unusual dangers. The Supreme Court essentially eliminated that path.¹ The doctrine applies to all types of hirers, from large commercial property owners down to individual homeowners, as long as the injured worker’s employer qualifies as an independent contractor.

Workers’ compensation is the economic foundation that holds the rule together. California Labor Code Section 3600 makes workers’ compensation the exclusive remedy for employees injured on the job, and every contractor is required to carry coverage.² When a property owner pays a contractor $200,000 for a project, the contractor’s workers’ compensation premiums are baked into that price. Letting the injured worker also sue the owner would mean the owner pays twice for the same risk.

Exception One: Retained Control That Affirmatively Contributes to the Injury

The first and most heavily litigated exception comes from Hooker v. Department of Transportation, decided in 2002. A hirer who retains control over safety conditions and exercises that control in a way that “affirmatively contributed” to the worker’s injury can be held liable.³ The critical word is “affirmatively.” Simply having the contractual right to stop unsafe work or inspect the site is not enough.

The court drew a sharp line between active interference and passive oversight. If a hirer notices a contractor doing something dangerous and does nothing about it, that failure alone does not create liability. Privette still protects a hirer whose “sole factual basis for the claim is that the hirer failed to exercise a general supervisory power to require the contractor to correct an unsafe procedure or condition of the contractor’s own making.”³

What counts as an affirmative contribution? Directly ordering a contractor to use an unsafe method qualifies. So does promising to handle a specific safety measure and then failing to follow through, because the contractor’s crew may rely on that promise and skip their own precautions.³ A general contractor who tells a subcontractor to skip fall protection to meet a deadline has taken an action that directly shaped the safety conditions. That’s the kind of conduct this exception targets.

This is where most plaintiff claims get tested, and where most of them fail. Courts have consistently required more than general oversight. The hirer’s conduct has to be a proximate cause of the injury in a direct sense, not a derivative one.

Exception Two: Concealed Hazards the Landowner Knew About

The second exception, established in Kinsman v. Unocal Corp. in 2005, applies when a landowner knows about a hidden danger on the property and fails to tell the contractor. It does not require the landowner to have retained any control over the work. The hazard belongs to the land, not to the work.⁴

Three conditions must all be present:

The property owner knew or should have known about a concealed, pre-existing hazardous condition on the premises.
The contractor did not know about the condition and could not have reasonably discovered it.
The landowner did not warn the contractor about the hazard.

The second element is where these claims often collapse. If the contractor could have found the danger through a reasonable inspection, the exception does not apply. In the 2024 appellate decision CBRE v. Superior Court, the court found the contractor could have asked about permits or used basic testing equipment to discover an electrical hazard, so the Kinsman exception did not save the claim.

A roofing contractor is expected to manage the risk of falling, because that’s a standard part of the job. But if the roof has a hidden structural defect that makes it likely to give way under normal foot traffic, and only the property owner knows about it, the owner has to speak up. Underground chemical contamination, concealed asbestos, or an unmarked electrical line running through a wall are the kinds of hazards this rule covers.⁴

Exception Three: Defective Equipment Supplied by the Hirer

The third exception comes from McKown v. Wal-Mart Stores, Inc., also decided in 2002. The court held that “a hirer is liable to an employee of an independent contractor insofar as the hirer’s provision of unsafe equipment affirmatively contributes to the employee’s injury.”⁵

When a hirer supplies tools, machinery, or scaffolding for the contractor’s use, the hirer takes on responsibility for those items being safe. A contractor’s expertise in roofing does not make them responsible for discovering a hidden defect in a crane the hirer provided. Putting a specific piece of equipment into the work environment is an affirmative choice by the hirer, and if that equipment turns out to be defective, the hirer cannot fall back on Privette’s delegation theory.

The exception is narrower than it might first appear. It applies to equipment the hirer provides, not equipment the contractor brings to the job or rents independently. If a general contractor mandates that subcontractors use a particular scaffold system and supplies the scaffolds, any mechanical failure traces back to the general contractor. If the subcontractor shows up with their own ladder and it breaks, that’s the subcontractor’s problem.⁵

Why Cal-OSHA Violations Don’t Create Their Own Path Around the Doctrine

Plaintiff attorneys have repeatedly argued that Cal-OSHA safety regulations create a nondelegable duty that survives the Privette doctrine. The California Supreme Court shut that argument down in SeaBright Insurance Co. v. US Airways in 2011. The court held that when a hirer engages an independent contractor, the hirer “presumptively delegated to [the contractor] any tort law duty of care the airline had under Cal-OSHA and its regulations to ensure workplace safety for the benefit of [the contractor’s] employees.”⁶

In that case, a maintenance worker was injured by an unguarded conveyor belt at the airport. The worker’s insurer argued that US Airways had a nondelegable duty under Cal-OSHA to install safety guards, and that this duty could not be passed to the contractor regardless of Privette. The court disagreed. The point of hiring a specialized maintenance contractor is that the contractor handles compliance with safety standards. Treating every regulatory safety requirement as nondelegable would swallow the Privette doctrine whole.⁶

The practical effect: you cannot repackage a retained-control claim as a “statutory duty” claim and avoid the affirmative-contribution requirement from Hooker. The analysis stays the same whether the alleged obligation comes from a regulation, a safety order, or general tort law.

How the Doctrine Protects Homeowners

Homeowners sometimes assume Privette only protects sophisticated commercial entities. The 2021 decision in Gonzalez v. Mathis settled that question. The California Supreme Court held that a homeowner who hires an independent contractor “presumptively delegates to the contractor a duty to ensure the safety of its workers,” including the duty to evaluate whether the work can be done safely despite known hazards on the property.⁷

The facts were striking. A professional window washer who had been cleaning a homeowner’s skylight since the 1990s knew the roof was slippery, had no tie-off points, and had a dangerously narrow walkway. He slipped and fell in 2012. The lower court tried to carve out a new exception for situations where no reasonable safety precaution could avoid the hazard. The Supreme Court rejected that reasoning, holding that “a landowner does not fail to delegate responsibility to the contractor for workplace safety simply because there exists a known hazard on the premises that cannot be readily addressed by the contractor.”⁸

If you hire a licensed professional to do work on your property and you do not interfere with how they do the job, Privette protects you. You are not required to independently assess whether the contractor’s safety measures are adequate. If you know about a hidden defect that the contractor cannot discover through ordinary inspection, the Kinsman concealed-hazard exception still applies, homeowner or not.

Where the Doctrine Doesn’t Reach

A few boundaries matter because readers often assume Privette covers more than it does.

Misclassified employees. The entire framework depends on the injured worker being employed by a genuinely independent business. If the worker is actually your employee under California law, Privette never enters the picture. California uses the multi-factor Borello test to decide this, with the primary question being whether the hirer has the right to control the manner and means by which the work is done.⁹ Classification mistakes have consequences well beyond Privette, but for this doctrine specifically, misclassification means no shield.

Indemnity clauses. Even with Privette in place, construction contracts routinely allocate risk through indemnity. California Civil Code Section 2782 voids any indemnity provision in a construction contract that forces one party to cover losses caused by the other party’s sole negligence or intentional misconduct. Private property owners who are not acting as contractors themselves also cannot shift liability for their own active negligence onto a contractor.¹⁰

OSHA enforcement. The Privette doctrine governs civil tort liability. It does not shield anyone from federal workplace safety enforcement. OSHA’s multi-employer citation policy, Directive CPL 02-00-124, allows the agency to cite any employer whose role on a shared jobsite contributed to a safety violation, even if that employer’s own workers were not exposed to the hazard.¹¹ A general contractor can win a Privette defense in court and still face fines as a controlling employer. After SeaBright, though, a Cal-OSHA violation does not by itself create a tort duty to the contractor’s employees.⁶

Deadline to file suit. If one of the exceptions applies and you have a viable civil claim against a hirer, California gives you two years from the date of injury to file a personal injury lawsuit under Code of Civil Procedure Section 335.1.¹² Missing it almost always kills the claim regardless of how strong the underlying facts are. Workers’ compensation claims follow a separate timeline and do not toll the deadline for a civil lawsuit against a third-party hirer.
