Subrogation law is not uniform. A waiver of subrogation clause that is fully enforceable in Texas may be void in New York. A workers' compensation subrogation right that exists in California may operate under entirely different rules in Ohio. For GCs working across multiple states, this patchwork of regulations creates compliance complexity that a one-size-fits-all contract cannot address.

This guide maps the state-specific subrogation rules that directly affect construction contracts, insurance requirements, and claim management.

Why State Law Matters for Construction Subrogation

Three areas of state law directly shape subrogation outcomes in construction:

Anti-indemnity statutes. Many states restrict or prohibit contractual indemnification for a party's own negligence. These statutes often affect waiver of subrogation clauses because courts view subrogation waivers as a form of indemnification. If the state's anti-indemnity statute prohibits broad indemnification, it may also invalidate a broad waiver of subrogation.

Workers' compensation subrogation statutes. Every state has its own WC act governing when and how a workers' comp carrier can pursue third parties. These statutory provisions override contract language and insurance policy terms.

Insurance regulation. Some states regulate the availability and pricing of waiver of subrogation endorsements. State insurance departments may restrict certain endorsement forms or mandate specific surcharges.

States That Restrict Waiver of Subrogation

The following states have statutes or case law that limit the enforceability of waiver of subrogation clauses in construction contracts.

New York

New York General Obligations Law Section 5-322.1 voids agreements in construction contracts that purport to indemnify a party for its own negligence. Courts have extended this to waiver of subrogation clauses in some contexts.

However, the statute applies to agreements that require indemnification for the indemnitee's negligence. A mutual waiver of subrogation (where both parties waive, covering each party's own losses regardless of fault) has been upheld by several New York courts because it is not an indemnification agreement, it is a risk allocation mechanism.

Practical guidance for GCs in New York: Use mutual waivers of subrogation rather than one-way waivers. Ensure the waiver clause is clearly separate from the indemnification clause. Consult New York counsel before relying on broad waiver language.

Illinois

The Illinois Insurance Code and anti-indemnity provisions (740 ILCS 35/1) void indemnification clauses in construction contracts to the extent they indemnify a party for its sole negligence. Illinois courts have examined waiver of subrogation clauses under this framework.

Waiver of subrogation under property insurance (such as builder's risk) is generally enforceable in Illinois. Waiver under liability insurance is more contested, particularly when the waiver effectively shields a party from the consequences of its own negligence.

Practical guidance for GCs in Illinois: Structure waivers to apply to losses covered by insurance, consistent with the AIA A201 approach. Avoid language that appears to waive liability for sole negligence.

Virginia

Virginia's anti-indemnity statute (Virginia Code Section 11-4.1) prohibits indemnification clauses in construction contracts that require indemnification for the indemnitee's sole negligence. Virginia courts have been conservative in interpreting waiver of subrogation provisions.

Practical guidance for GCs in Virginia: Limit waivers to losses covered by insurance. Include a carve-out for sole negligence of the waiving party. Obtain Virginia-specific legal review of waiver clauses.

Louisiana

Louisiana's anti-indemnity statute (Louisiana Revised Statutes 9:2780.1) restricts indemnification in construction contracts. Waiver of subrogation clauses must be carefully drafted to avoid being treated as prohibited indemnification.

Louisiana also operates under a civil law system rather than common law, which affects how courts interpret insurance contract provisions including subrogation clauses.

Practical guidance for GCs in Louisiana: Work with Louisiana counsel experienced in civil law insurance provisions. Standard common-law waiver language may not be effective.

Workers' Compensation Subrogation by State

Workers' comp subrogation is the most variable area of construction subrogation law. Each state's WC act creates its own framework for third-party recovery.

Exclusive Remedy and Third-Party Claims

Under every state's WC act, the employer's liability for workplace injuries is limited to WC benefits (the exclusive remedy doctrine). But when a third party (not the employer) causes the injury, the injured worker and/or the WC carrier can pursue the third party.

This is where subrogation enters: the WC carrier pays benefits and then pursues the third party to recover those payments.

State Variations in WC Subrogation

States with employer-favorable WC subrogation (strong carrier recovery rights):

Texas: The WC carrier has an automatic subrogation lien on any third-party recovery. The carrier can pursue the third party directly or intervene in the worker's third-party lawsuit. Recovery is not reduced by the carrier's share of attorney fees.
Georgia: The WC carrier has a statutory lien on third-party recoveries. The carrier must be given notice of any third-party action and has the right to intervene.
Florida: The WC carrier has a lien on the first dollars recovered from the third party, subject to a pro-rata share of the worker's attorney fees under the Made Whole doctrine as modified by statute.

States with worker-favorable WC subrogation (limited carrier recovery):

Pennsylvania: The WC carrier's subrogation right is subordinate to the worker's right to be "made whole." The carrier does not recover until the worker has been fully compensated for all losses, including non-economic damages that WC does not cover.
New Jersey: The WC carrier's lien is reduced by the worker's pro-rata share of litigation costs. The Made Whole doctrine applies, limiting recovery when the worker's total damages exceed the third-party recovery.
Wisconsin: The WC carrier's subrogation right is statutory (WI Stat. 102.29) but subject to significant reductions for the worker's attorney fees and costs.

Monopolistic state fund states:

Ohio: The Ohio Bureau of Workers' Compensation (BWC) handles all WC claims. BWC has subrogation rights under Ohio Revised Code Section 4123.93. The BWC's subrogation process operates independently of private carrier practices. GCs operating in Ohio must coordinate waiver requests through the BWC, not a private insurer.
North Dakota: The North Dakota Workforce Safety & Insurance (WSI) fund administers WC. Subrogation is handled by the state fund. Waiver of subrogation on WC may not be available through the state fund.
Washington: The Washington State Department of Labor & Industries administers WC. The state fund has subrogation rights and handles recoveries through its legal department.
Wyoming: The Wyoming Workers' Safety and Compensation Division administers WC with statutory subrogation provisions.

Impact on Construction Contracts

WC subrogation variations affect GCs in two ways:

First, the availability of WC waiver endorsements varies by state. In monopolistic fund states, waiver endorsements may not be available at all. In other states, the state WC rating bureau may mandate specific surcharges for waivers.

Second, even when a WC waiver endorsement is obtained, state statutory subrogation rights may override the waiver. Some states' WC acts grant the carrier an irrevocable right to pursue third parties that cannot be waived by contract or endorsement.

GCs should verify with legal counsel in each state whether WC subrogation waivers are (a) available from the carrier or state fund and (b) legally enforceable under the state's WC act.

State Anti-Subrogation Rules in Property Insurance

Several states have adopted anti-subrogation rules specific to property insurance in construction, often based on the completed and accepted doctrine or the economic loss rule.

The Completed and Accepted Doctrine

In some jurisdictions, once the owner accepts the completed project, the general contractor's liability for property damage to the work itself is limited. This affects subrogation because the owner's property insurer cannot subrogate against the GC for property damage to accepted work.

States recognizing some form of this doctrine include Maryland, Virginia, and the District of Columbia. The doctrine has been limited or abolished in many other states.

The Economic Loss Rule

The economic loss rule prevents recovery in tort for purely economic losses (as opposed to personal injury or property damage). In states that apply the economic loss rule strictly, a property insurer's subrogation claim may be barred if the loss is characterized as economic rather than physical damage.

States with strong economic loss rule application in construction include Florida (under the Tiara Condo case line), Virginia, and North Carolina.

Multi-State Project Considerations

GCs operating across state lines face compound subrogation complexity.

Choice of Law Provisions

Subcontracts should include a choice of law provision specifying which state's law governs. For subrogation purposes, the governing law affects:

Whether waiver of subrogation clauses are enforceable
How WC subrogation rights are determined
Whether anti-indemnity statutes apply

The choice of law provision should align with the project location. A subcontract for work in New York governed by Texas law may face enforcement challenges in New York courts.

Multi-State Insurance Programs

Subs working across multiple states may carry separate WC policies for each state or a multi-state WC policy. The waiver of subrogation endorsement must be on the policy covering the state where the work is performed. A waiver on the sub's home-state WC policy does not apply to the monopolistic state fund policy covering work in Ohio.

Coordination Protocol

For multi-state GCs, we recommend creating a state-specific subrogation compliance matrix:

State	Anti-Indemnity Restriction	WC Waiver Available	WC Fund Type	Special Considerations
TX	Limited (Chapter 151)	Yes	Private carrier	Strong carrier subrogation rights
NY	GOL 5-322.1	Yes	Private carrier	Mutual waivers preferred
CA	Civil Code 2782	Yes	Private carrier	Labor Code 3852 governs WC subrogation
OH	Moderate	Limited (BWC)	Monopolistic fund	BWC handles subrogation directly
FL	Moderate	Yes	Private carrier	Made Whole doctrine applies to WC
IL	740 ILCS 35/1	Yes	Private carrier	Property waivers generally enforceable

This matrix should be reviewed with legal counsel and updated annually as state laws evolve.

Case Study: A Multi-State GC Navigates Subrogation Complexity

A national GC operates projects in Texas, New York, California, Ohio, and Florida. A mechanical sub working across three of these projects causes water damage on the Texas project and an employee injury on the Ohio project.

Texas water damage claim: The GC's builder's risk policy pays $380,000. The GC's insurer subrogates against the mechanical sub's CGL carrier. The subcontract includes a mutual waiver of subrogation. The sub's CGL carries a CG 24 04 endorsement. The subrogation demand is waived. Total cost to GC: the $380,000 is absorbed by the GC's builder's risk carrier. No further action.

Ohio employee injury claim: The mechanical sub's employee is injured by a floor opening the GC's crew left unbarricaded. Ohio BWC pays WC benefits and pursues subrogation against the GC under Ohio Revised Code 4123.93. The subcontract includes a waiver of WC subrogation, but Ohio BWC does not honor private contract waivers of its statutory subrogation rights. BWC pursues the GC's CGL carrier for $210,000.

Outcome: The same sub, the same contract language, and two different results based entirely on state law. Texas honored the contractual waiver. Ohio's statutory framework overrode it.

This is why state-specific analysis is not optional for multi-state GCs.

Using SubcontractorAudit Across State Lines

SubcontractorAudit supports multi-state compliance by allowing GCs to configure project-specific insurance requirements by state. The platform:

Applies state-specific waiver availability rules (flagging WC waivers as unavailable in monopolistic fund states)
Tracks which endorsement forms are required in each state
Archives compliance documentation by project location
Generates state-specific compliance reports for risk management review

For GCs managing projects in 5+ states, the platform reduces the risk of applying the wrong compliance standard to the wrong state.
