Understanding project insurance best practices across different states is critical for general contractors working in multiple jurisdictions. Each state sets its own workers' compensation mandates, minimum liability requirements, indemnification rules, and endorsement standards. A practice that keeps you compliant in Georgia may leave you exposed in New York. In 2025, GCs operating across state lines reported spending an average of 14 hours per month navigating state-specific insurance requirements.

This state-by-state guide covers the key insurance variables that affect project compliance in the most active construction markets.

Why State Requirements Vary

Construction insurance regulation is primarily a state function. No federal standard governs minimum coverage limits or endorsement requirements for private construction projects. Federal projects follow FAR and specific agency requirements, but private and state-funded projects follow state law.

Three factors create the most variation between states: workers' compensation mandates, anti-indemnity statutes, and additional insured endorsement requirements. GCs must track all three for every state where they perform work.

Workers' Compensation Requirements by State

Workers' compensation is mandatory for construction employers in 49 states. Texas is the only state that allows employers to opt out, though GCs in Texas face increased common-law liability when hiring non-subscriber subcontractors.

State	WC Required for Construction	Employee Threshold	Sole Proprietor Exempt	Key Notes
California	Yes	1+ employees	Yes	Strictest enforcement, heavy penalties
Texas	No (optional)	N/A	N/A	Non-subscribers face tort liability
Florida	Yes	1+ employees	No (construction)	No exemptions for construction
New York	Yes	1+ employees	Yes	High rates, mandatory coverage B
Illinois	Yes	1+ employees	Yes	Audit frequency increasing
Pennsylvania	Yes	1+ employees	Yes	Subcontractor exclusions limited
Ohio	Yes (state fund)	1+ employees	Yes	Monopolistic state fund
Georgia	Yes	3+ employees	Yes	Higher threshold than most states
North Carolina	Yes	3+ employees	Yes	Similar to Georgia
Washington	Yes (state fund)	1+ employees	No	Monopolistic state fund

States with monopolistic state funds (Ohio, Washington, Wyoming, North Dakota) require coverage through the state program. Subcontractors from other states must obtain separate coverage through the state fund for work performed there.

Anti-Indemnity Statutes

Anti-indemnity statutes limit the scope of risk management through contractual indemnification in construction. At least 42 states restrict or prohibit broad-form indemnification.

Broad-form prohibited states. These states void any clause that requires the sub to indemnify the GC for the GC's own negligence. Examples include California, Texas, New York, Florida, Illinois, and Georgia.

Intermediate-form required states. Most states allow intermediate-form indemnification, which transfers risk for the sub's negligence and any shared fault, but not for the GC's sole negligence.

Limited-form only states. A few states restrict indemnification to the sub's own negligence only. The sub cannot be required to indemnify the GC for any portion of the GC's fault.

GCs must match their subcontract indemnification language to the applicable state statute. Using a non-compliant clause renders it void, removing the contractual risk transfer the GC expected.

Additional Insured Endorsement Standards

The specific additional insured endorsement form required varies by state custom and contract language.

CG 20 10. The most common additional insured endorsement for ongoing operations. Provides coverage to the GC for the sub's negligent acts during active construction. Multiple editions exist (1985, 1993, 2004, 2013). The 2004 edition is the most GC-friendly.

CG 20 37. Covers completed operations as additional insured. Paired with CG 20 10 to provide both ongoing and completed operations coverage.

CG 20 38. A more restrictive form that limits additional insured coverage. Some carriers use this form instead of CG 20 10. GCs should verify which form is attached and reject CG 20 38 when the contract requires CG 20 10.

State-specific forms. Texas and a few other states have carrier-specific endorsement forms that replace ISO standard forms. Verify that non-standard endorsements provide equivalent coverage.

Case Study: Multi-State GC Compliance

A mid-size GC operating in California, Texas, and Florida illustrates how state variations create compliance complexity.

California project. The GC must verify workers' compensation for every sub, including sole proprietors with no employees (if the sub hires anyone during the project). Anti-indemnity statute prohibits broad-form. Additional insured endorsement must include both CG 20 10 and CG 20 37. AB 5 worker classification rules add complexity to independent contractor determinations.

Texas project. Workers' compensation is optional. The GC must verify whether each sub carries coverage. Non-subscriber subs increase the GC's tort liability. Broad-form indemnification is prohibited under the Texas Oilfield Anti-Indemnity Act for oil and gas projects but allowed for other construction with limitations. The Texas Department of Insurance requires specific endorsement forms.

Florida project. Workers' compensation required for all construction employers with 1 or more employees. No sole proprietor exemption in construction. Certificates must be delivered within 3 days of contract execution under some owner specifications. Anti-indemnity statute prohibits broad-form.

Each state requires a different subcontract template, different insurance specifications, and different verification procedures. Using a single template across all three states creates compliance gaps.

How to Build a Multi-State Compliance Program

GCs operating in multiple states need a structured approach.

State-specific templates. Maintain separate subcontract templates and insurance requirement schedules for each state. Update templates when state laws change.

Jurisdiction tracking. When a project is created in your compliance system, tag it with the applicable state. This triggers the correct verification rules for workers' compensation, indemnification, and endorsements.

Legal review cadence. Review state-specific requirements with construction counsel at least annually. Several states update anti-indemnity statutes and workers' compensation rules each legislative session.

Subcontractor education. Many subs do not understand state-specific requirements. Provide clear guidance on what their insurance program must include for work in each state.

FAQs

Which states have the strictest construction insurance requirements? California, New York, and Florida consistently rank as the strictest states for construction insurance compliance. California requires workers' compensation for all employers with one or more employees and has aggressive enforcement. New York's Labor Law 240 creates unique liability exposure. Florida prohibits sole proprietor exemptions in construction.

Do insurance requirements change between public and private projects? Yes. Public projects often impose higher minimum coverage limits and additional endorsement requirements beyond what state law mandates. Federal projects follow FAR regulations. State-funded projects may require specific bond forms and higher liability limits. Always review the project specifications separately from state minimums.

How do anti-indemnity statutes affect project insurance? Anti-indemnity statutes limit the GC's ability to transfer risk through subcontract language. In states that prohibit broad-form indemnification, the GC cannot require the sub to cover the GC's own negligence. This makes insurance coverage even more important as the contractual backstop is reduced.

Can a GC use the same subcontract template in every state? No. Indemnification clauses, insurance requirements, and workers' compensation provisions must align with each state's laws. Using a non-compliant template renders key provisions unenforceable. Maintain state-specific templates and update them when laws change.

What is the difference between CG 20 10 and CG 20 37 endorsements? CG 20 10 provides additional insured coverage for ongoing operations during active construction. CG 20 37 provides additional insured coverage for completed operations after the work is finished. Most GC contracts should require both forms to provide full project lifecycle coverage.

How do monopolistic state fund states affect subcontractor compliance? In monopolistic state fund states (Ohio, Washington, Wyoming, North Dakota), subcontractors must obtain workers' compensation through the state program. Out-of-state subs cannot use their home state policy. This requires separate coverage procurement for work in these states, which adds time and cost to the enrollment process.
