California Civil Code Section 2782: Anti-Indemnity Rules in Construction

California Civil Code Section 2782 voids any clause in a construction contract that tries to make one party cover another party’s sole negligence, willful misconduct, or design defects furnished by that other party. The statute, together with its companion sections (2782.05, 2782.1, 2782.2, 2782.5, 2782.6, and 2782.8), sets the ceiling for how far indemnity can go between contractors, subcontractors, property owners, public agencies, and design professionals. A clause that crosses the line is unenforceable as a matter of California public policy, and no creative drafting brings it back.

The Core Rule

Subdivision (a) is the anchor. A construction contract provision that purports to indemnify the promisee against liability for the promisee’s sole negligence, willful misconduct, or defects in design furnished by the promisee is void.¹ The word “sole” matters. If the party seeking indemnity was the only one at fault, the clause fails. If fault is shared, the analysis moves to the subdivision or companion statute that fits the project.

The prohibition covers liability for death, bodily injury, property damage, and any other loss or expense connected to the construction work. It reaches any provision “contained in, collateral to, or affecting” a construction contract, so side letters and ancillary documents are inside the fence too.¹

From there, the specific rule you follow depends on who the parties are.

Public Agency Contracts

Section 2782(b) sets a stricter floor when a public agency is a party. For contracts entered on or after January 1, 2013, a clause that imposes liability on a contractor, subcontractor, or supplier for the public agency’s active negligence is void, and so is a clause that tries to relieve the public agency of responsibility for its own active negligence.¹

The active-passive distinction decides a lot of close calls. Active negligence is direct participation in the negligent act, such as a public agency employee operating equipment improperly. Passive negligence is more indirect, like failing to discover a defect created by someone else. A public agency can still shift its passive negligence by contract. It cannot push its active wrongdoing onto the contractor.

Private Property Owner Contracts

Subdivision (c) does the parallel work for private owners. For construction contracts entered on or after January 1, 2013, with a private owner who is not acting as a contractor or material supplier, an indemnity clause is unenforceable to the extent of the owner’s active negligence.¹

“Owner” here is broad: anyone holding an interest in the property other than a mortgage or security interest. The subdivision does not reach a homeowner doing an improvement project on their own single-family dwelling; that situation sits under the residential construction rules.

Residential Construction

Subdivision (d), effective for contracts entered after January 1, 2009, targets residential construction as defined under California’s Right to Repair Act (Civil Code sections 895 and following). A builder or general contractor cannot require a subcontractor to indemnify them, including defense costs, for construction defect claims that arise from the builder’s or GC’s own negligence, or from the negligence of their other agents and independent contractors.² The clause is also unenforceable to the extent the claims fall outside the subcontractor’s contractual scope of work. These protections cannot be waived by agreement.

For a residential subcontractor, the practical result is simple. You can be made responsible for indemnifying defects that trace back to your own work. You cannot be made responsible for the rest.

Subcontractors on Commercial Projects

Section 2782.05 reshaped commercial construction contracting. For contracts entered on or after January 1, 2013, it voids indemnity clauses between subcontractors and general contractors or construction managers to the extent claims arise from the GC’s active negligence or willful misconduct, or from work outside the subcontractor’s scope.³ These protections cannot be waived or modified by contractual agreement, act, or omission.

Before this section existed, a GC on a commercial project could demand that an electrical subcontractor indemnify the GC for the GC’s own negligent supervision of the plumbing crew. That arrangement is no longer enforceable. A subcontractor’s indemnity obligation is now tied to its own scope of work and, at most, the GC’s passive negligence.

Section 2782.05 carries a long list of carve-outs. It does not reach:

Residential construction contracts already covered by subdivision (d) of Section 2782
Direct contracts with public agencies governed by subdivision (b)
Direct contracts with private property owners governed by subdivision (c)
Wrap-up insurance programs
Insurance requirements in the contract that require the subcontractor to purchase coverage for its own acts or omissions, including additional insured endorsements
Workers’ compensation benefits and governmental immunity protections
Surety bond agreements
Breach of contract or warranty claims that exist independently of any indemnity obligation

The insurance carve-out catches people off guard. A GC cannot contractually require a subcontractor to indemnify the GC for the GC’s active negligence, but the GC can still require the subcontractor to name the GC as an additional insured on the subcontractor’s liability policy. The additional insured endorsement runs through the insurance policy, so it operates under a separate legal framework from the indemnity rules.³

Design Professionals

Section 2782.8 is the most targeted piece of the framework. For design professional services contracts entered on or after January 1, 2018, indemnity clauses are unenforceable unless the claims arise from the design professional’s own negligence, recklessness, or willful misconduct.⁴ Even where indemnity is enforceable, defense costs charged to the design professional cannot exceed their proportionate percentage of fault.

“Design professional” covers architects, landscape architects, professional engineers, professional land surveyors, and business entities offering those services.⁴ Requests for proposals, invitations for bids, and other solicitation documents are deemed to incorporate these protections by reference, whether or not the contract mentions them. The protections cannot be waived.

The proportionate-fault cap on defense costs matters in practice. An architect found 20% at fault on a project with $500,000 in defense costs has a maximum exposure of $100,000 for those costs. If another responsible party becomes bankrupt or dissolves, the design professional must meet and confer with the remaining parties about covering the unpaid share.

Duty to Defend Comes Earlier Than Duty to Indemnify

One distinction surprises people more than any other. The duty to defend and the duty to indemnify are not the same obligation, and they are not triggered at the same time. The California Supreme Court drew the line in Crawford v. Weather Shield Mfg. (2008). The duty to defend attaches when a lawsuit is filed alleging claims covered by the indemnity agreement. The duty to indemnify only arises once actual liability is established.

The practical consequence: a subcontractor who signed an indemnity agreement with a defense obligation may have to fund the GC’s legal defense from the moment the complaint lands, before anyone has determined whether the subcontractor was negligent. The Crawford court held that the duty to defend “arises immediately upon a proper tender of defense” and “cannot depend on the outcome of that litigation.”

Section 2782.8 caps a design professional’s defense cost obligation at the professional’s proportionate share of fault.⁴ Under Section 2782.05, a subcontractor’s duty to defend tracks the same limits as the indemnity obligation itself, so a subcontractor cannot be required to defend claims arising from the GC’s active negligence or from work outside the sub’s scope.³

What the Statute Does Not Reach

Several arrangements sit outside the anti-indemnity rules even when the main indemnity clause is void.

Subdivision (a) of Section 2782 states that it does not affect the validity of any insurance contract, workers’ compensation agreement, or agreement issued by an admitted insurer.¹ This is why additional insured requirements survive in construction contracts where the indemnity clause itself would not.

Section 2782.5 lets the parties to a construction contract negotiate and expressly agree on how to allocate, release, limit, or exclude liability for design defects, so long as the allocation is expressly negotiated rather than buried in boilerplate.⁵

Two narrow carve-outs let a party indemnify a professional for the professional’s own negligence in specific circumstances. Section 2782.2 permits a plant or facility owner to indemnify a professional engineer providing inspection services, but only if the owner owns the facility, undergoes annual independent audits, has a net worth exceeding $10 million, is self-insured for facility-related liability, and the indemnification excludes the first $250,000 of liability; willful misconduct is never covered.⁶ Section 2782.6 lets a party responsible for contamination indemnify a professional engineer or geologist hired to evaluate or remediate hazardous materials, limited to damages arising from subterranean contamination or concealed conditions, excluding the first $250,000 of liability and excluding the engineer’s or geologist’s gross negligence or willful misconduct.⁷

What Happens When a Clause Violates the Statute

A prohibited indemnity clause is “void and unenforceable” under Section 2782(a). Courts generally sever the offending provision rather than throwing out the full contract, so the rest of the obligations stand. The clause itself is gone. There is no judicial reformation into an enforceable version, and for several of the companion sections (including 2782.05 and 2782.8) the statute specifically states the protections cannot be waived or modified by contractual agreement, act, or omission.³

The exposure runs in both directions. A GC that drafted a contract expecting broad-form indemnity now carries the loss it thought it had shifted. A subcontractor pressured to sign an aggressive clause often has more protection than the contract language suggests. Before signing or drafting, match the clause to the subdivision that fits the project type and your role. A clause that is routine in one setting may be unenforceable in another.
