Disability and workers compensation operate as separate systems, but GCs working across state lines must track both. Five states require employers to carry state disability insurance (SDI) in addition to WC: New York, New Jersey, California, Hawaii, and Rhode Island. Four states operate monopolistic WC funds that prohibit private carriers. When your subs work in multiple states, the compliance matrix gets complicated fast.

This guide breaks down state-specific requirements with concrete compliance scenarios for GCs managing multi-state construction projects.

The Four Monopolistic Workers Compensation States

Ohio, North Dakota, Washington, and Wyoming require all employers to purchase WC from the state fund. No private carrier can write WC in these states.

Ohio: Bureau of Workers Compensation (BWC)

Ohio BWC covers approximately 250,000 employers. Construction employers pay rates ranging from $4.50 to $28.00 per $100 of payroll depending on the trade classification.

GC compliance requirements:

Sub must provide Ohio BWC policy number (not ACORD certificate)
Verify active status at ohiobwc.com employer lookup
Ohio allows group rating programs that reduce premiums by 20-50%
Self-insurance available for employers with $5 million+ net worth

Scenario: Your sub is based in Kentucky with a private carrier WC policy. They send workers to your Cincinnati project. Their Kentucky WC policy does not cover Ohio because Ohio is a monopolistic state. The sub must purchase a separate Ohio BWC policy before any worker steps on your job site.

Washington: Department of Labor & Industries (L&I)

Washington's L&I system uses an employer account number instead of a policy number. Both the employer and employee pay premiums. Washington is the only state where workers contribute to WC premiums.

GC compliance requirements:

Sub must provide L&I account number
Verify at lni.wa.gov employer lookup
Employee premium deductions must appear on pay stubs
Contractors must be registered with L&I before performing work

Scenario: A California sub wins a project in Seattle. Their private carrier WC policy excludes Washington (monopolistic state). The sub registers with Washington L&I, obtains an account number, and provides it to you. You verify active status online.

North Dakota: Workforce Safety & Insurance (WSI)

North Dakota WSI covers approximately 24,000 employers. Premium rates for construction range from $3.80 to $22.50 per $100 of payroll.

GC compliance requirements:

Sub must provide WSI account number
Verify at workforcesafety.com
Out-of-state employers working in ND must register with WSI before starting work
Coverage extends to all employees working in ND, even temporarily

Wyoming: Workers' Compensation Division

Wyoming's system covers employers through the state fund. Construction rates range from $5.20 to $19.80 per $100 of payroll.

GC compliance requirements:

Sub must provide WC Division account number
Verify through the Wyoming Department of Workforce Services
Out-of-state contractors must register before commencing work

Monopolistic State	Fund Name	Verification Portal	Construction Rate Range
Ohio	BWC	ohiobwc.com	$4.50-$28.00 per $100
Washington	L&I	lni.wa.gov	$5.10-$32.00 per $100
North Dakota	WSI	workforcesafety.com	$3.80-$22.50 per $100
Wyoming	WC Division	wyomingworkforce.org	$5.20-$19.80 per $100

The Five State Disability Insurance States

These five states require employers to provide short-term disability insurance covering non-work-related injuries and illnesses. This coverage is separate from WC, which covers only work-related injuries.

New York: Disability Benefits Law (DBL)

New York requires all employers with one or more employees to carry disability benefits insurance. The maximum weekly benefit is $170 (unchanged since 1989). Employees can contribute up to $0.60 per week through payroll deductions.

Construction impact: NY DBL applies to all construction workers. GCs must verify that subs carry both WC and DBL coverage. The DBL policy appears on a separate section of the ACORD certificate or on a standalone NY DBL certificate.

New York also enacted Paid Family Leave (PFL) in 2018, adding another mandatory coverage. PFL provides up to 12 weeks of leave at 67% of the employee's average weekly wage. The 2026 maximum weekly PFL benefit is $1,177.32.

What to verify: Certificate of insurance showing active NY DBL and PFL coverage alongside WC. All three are required.

New Jersey: Temporary Disability Benefits (TDB)

New Jersey TDB covers non-work-related injuries and illnesses. The 2026 maximum weekly benefit is $1,025. Both employers and employees contribute through payroll taxes.

Construction impact: Every sub working in NJ must carry TDB coverage. Employers can provide TDB through the state plan, a private carrier, or a self-insured program.

What to verify: Proof of NJ TDB coverage. If the sub uses the state plan, verify through the NJ Department of Labor. If private plan, verify through the carrier.

California: State Disability Insurance (SDI)

California SDI covers non-work-related disabilities. The 2026 maximum weekly benefit is $1,681. SDI is funded entirely through employee payroll deductions at 1.1% of wages up to $161,813.

Construction impact: California SDI applies to all W-2 employees. Independent contractors are exempt. Since construction workers in California are presumed to be employees under AB 5, virtually all construction workers qualify for SDI.

What to verify: California SDI is an employee-funded program administered by the Employment Development Department (EDD). Employers do not purchase a separate policy. Verify the sub is registered with EDD and withholding SDI contributions.

Hawaii: Temporary Disability Insurance (TDI)

Hawaii TDI covers non-work-related injuries. The 2026 maximum weekly benefit is $765. Employers fund TDI through a private carrier, the state TDI fund, or self-insurance.

Construction impact: All employers with one or more employees must provide TDI coverage. Hawaii also requires employers to provide Prepaid Health Care for employees working 20+ hours per week.

What to verify: Proof of TDI coverage. Request the TDI certificate or policy information alongside the WC certificate.

Rhode Island: Temporary Disability Insurance (TDI)

Rhode Island TDI covers non-work-related disabilities. The 2026 maximum weekly benefit is $1,007. TDI is funded through employee payroll contributions at 1.1% of the first $84,000 in wages.

Construction impact: Like California SDI, Rhode Island TDI is employee-funded and administered by the state. Employers must register with the RI Department of Labor and Training.

State	Program Name	Max Weekly Benefit (2026)	Funded By	GC Verification
New York	DBL + PFL	$170 (DBL) / $1,177 (PFL)	Employer + Employee	Separate certificate required
New Jersey	TDB	$1,025	Employer + Employee	State plan or carrier proof
California	SDI	$1,681	Employee only	EDD registration
Hawaii	TDI	$765	Employer	Private carrier or state certificate
Rhode Island	TDI	$1,007	Employee only	State registration

Multi-State Compliance Scenarios

Scenario 1: Northeast Corridor Project

Your project spans New York, New Jersey, and Connecticut. You have 12 subs.

WC requirements: Standard competitive-state WC in all three states. Verify each sub's policy covers NY, NJ, and CT through Item 3A or 3C.

Disability requirements: NY requires DBL and PFL. NJ requires TDB. Connecticut has no mandatory disability program. Three of your 12 subs are based in Pennsylvania and have never carried NY DBL or NJ TDB. They need to purchase this coverage before mobilizing.

Compliance action items:

Collect WC certificates covering NY, NJ, CT for all 12 subs
Collect NY DBL and PFL certificates for subs working in NY
Collect NJ TDB proof for subs working in NJ
Set separate expiration alerts for WC and disability coverages

Scenario 2: Pacific Northwest Project

Your project is in Washington State with some work crossing into Oregon.

WC requirements: Washington is monopolistic. Every sub needs a Washington L&I account. Oregon is competitive. Subs need standard WC covering Oregon.

Disability requirements: Neither Washington nor Oregon requires state disability insurance. No additional disability verification needed.

Compliance action items:

Verify each sub has a Washington L&I account (check lni.wa.gov)
Verify each sub's private carrier WC covers Oregon
Watch for subs carrying only Oregon WC who lack Washington L&I registration

Scenario 3: Multi-Region National Project

Your company manages projects in Ohio, California, New York, and Texas.

WC requirements:

Ohio: monopolistic state, BWC account required
California: competitive state, private carrier or State Compensation Insurance Fund
New York: competitive state, private carrier or NY State Insurance Fund
Texas: WC optional (but contractually required by most owners)

Disability requirements:

Ohio: no state disability program
California: SDI (employee-funded, verify EDD registration)
New York: DBL and PFL (separate certificates required)
Texas: no state disability program

This scenario requires tracking four different WC verification methods and two different disability programs across four states. Manual tracking becomes unmanageable beyond a handful of subs.

Frequently Asked Questions

Do I need to verify state disability coverage for my subcontractors? In the five states requiring disability coverage (NY, NJ, CA, HI, RI), yes. If your sub's workers perform any work in these states, the sub must carry the required disability coverage. While enforcement targets the employer (your sub), GCs face exposure when subs lack proper coverage and injured workers pursue claims up the chain.

What is the difference between workers compensation and state disability insurance? Workers compensation covers injuries and illnesses arising from work. State disability insurance covers injuries and illnesses that are not work-related. A carpenter who breaks their arm on a job site files a WC claim. The same carpenter who breaks their arm skiing files a disability claim. Both provide wage replacement and medical benefits, but the trigger (work-related vs. non-work-related) determines which system applies.

How do monopolistic state WC requirements affect my subcontractor compliance? Subs entering monopolistic states (OH, ND, WA, WY) must purchase separate state fund coverage. Their existing private carrier WC policy does not cover these states. GCs must verify the sub has a state fund account before work begins. Failure to do so means the sub's workers are uninsured in that state, and the GC becomes the statutory employer.

Can a worker receive both workers compensation and disability benefits? Generally no. WC and state disability cover different triggers, so only one applies at a time. If an injury is work-related, WC pays. If non-work-related, disability pays. However, when a work injury leads to a concurrent non-work-related condition, coordination rules determine which program pays which portion. New York and California have specific coordination-of-benefits rules.

What penalties do I face for non-compliance with state disability requirements? Penalties vary by state. New York DBL violations carry penalties of $500 to $5,000. New Jersey TDB non-compliance results in fines plus liability for benefits owed. California SDI penalties apply to the employer who fails to withhold employee contributions. As a GC, your direct penalty exposure is limited, but subs in non-compliance create project delays and reputational risk.

How do I track both WC and disability compliance across multiple states? Create a compliance matrix listing every sub, every state where they work, and the specific requirements (WC type, disability requirement, special registrations). For manual tracking, use a spreadsheet with conditional formatting. For 10 or more subs across 3 or more states, automated platforms handle the complexity with state-specific verification rules and alert systems.
