Contractor Licensing Boards in 13 States and D.C. Just Ran a Joint Crackdown. Insurance Steps for Contractors Who Hire Subs

Status as of November 4, 2026: On November 2, 2026, the National Association of State Contractors Licensing Agencies (NASCLA) reported the results of its 2026 National Coordinated Enforcement Effort, held October 12–23. Fifteen regulatory agencies from 13 states and the District of Columbia took part, covering Alabama, Arizona, California, Connecticut, the District of Columbia, Florida, Michigan, Mississippi, Nevada, North Carolina (two agencies), Ohio, Oregon, Utah, and Washington. NASCLA says participants reported more than 3,900 jobsite and residential visits, with actions ranging from administrative citations and cease-and-desist orders to stop-work orders and criminal referrals.

Most headlines about these sweeps are written for homeowners. This post is for the licensed contractors on the other side of the job: general contractors, specialty trades, and anyone who hires subcontractors. When an unlicensed or uninsured sub is found on your site, the problem rarely stays with the sub. It can show up on your workers’ compensation audit, your general liability claim file, and your next renewal. This is brokerage guidance only. It is not legal advice.

What the agencies reported

Each state ran its own operation, so the numbers are not directly comparable. A few examples from the official releases:

• California: The Contractors State License Board (CSLB) reported 39 stings and sweeps resulting in 73 enforcement actions. Sweeps in 18 counties included 182 site visits, and CSLB separately issued 11 stop-work orders. CSLB noted that unlicensed operators often work without the legally required license or workers’ compensation insurance.
• Nevada: The Nevada State Contractors Board reported 45 unannounced jobsite visits, 406 license details verified, 42 criminal cases opened, and 24 cease-and-desist orders.
• Washington: The Department of Labor & Industries reported visiting 350 jobsites during focused enforcement on October 20–21, with 40 infractions for unlicensed and unregistered activity and 76 referrals to other L&I areas, including employer audits and safety concerns.
• Oregon and Utah: Oregon’s Construction Contractors Board reported 337 jobsite visits, and Utah’s Division of Professional Licensing reported 326 site checks and 49 administrative citations.

The common thread: regulators are checking licenses on active jobsites, not only after a complaint. If a sub on your project cannot show a license, the stop-work order or citation can delay your schedule, and the questions that follow often turn to insurance.

Why an unlicensed sub becomes your insurance problem

Rules vary by state, but the pattern is similar. In California, for example, Labor Code section 2750.5 presumes that a worker performing work that requires a contractor’s license is an employee rather than an independent contractor, and holding a valid license is a condition of independent contractor status. As a result, an unlicensed sub and its workers can be treated as your employees for workers’ compensation purposes if someone is hurt. Other states have their own rules for when a hiring contractor becomes responsible for a sub’s workers.

Insurers see the same risk at audit. Workers’ compensation policies, and many general liability policies, are auditable. If you paid a sub who cannot produce a valid certificate of insurance, the auditor may add those payments to your own exposure base, and the additional premium arrives after the policy year is over.

What to check on your insurance now

• Verify the license before the sub starts, not after the sweep. Check every subcontractor with the licensing agency in the state where the work is done, and confirm that the license classification matches the work they are doing. Save a dated screenshot or printout in the job file.
• Collect a current certificate of insurance from every sub. At a minimum, look for general liability and workers’ compensation, plus commercial auto if they drive to your sites. Our free COI checklist walks through what to look for, and our guide to certificates, additional insured endorsements, and class codes explains the details that most often get certificates rejected.
• Ask for additional insured status in writing. A certificate alone does not add you to the sub’s policy. Your subcontract should require additional insured status and, where available, waiver of subrogation, and the sub’s policy should carry the matching endorsement.
• Track expiration dates. A certificate that was valid in March may not be valid in November. Set reminders and request renewals before policies lapse, so you are not paying an uninsured sub without knowing it.
• Know your state’s workers’ compensation rules for subs. In California, by January 1, 2028, nearly every active CSLB license must have workers’ compensation (or a Certification of Self-Insurance) on file, which will change how many no-employee subs are documented. Other states set their own exemptions. If a sub claims an exemption, keep the paperwork.
• Prepare for audit. Keep subcontractor payments, certificates, and license checks organized by job. Clean records are the simplest way to keep uninsured-sub charges off your workers’ compensation and general liability audits.
• Keep your own house in order. Inspectors check your license, too. Make sure your license, contractor bond, and required workers’ compensation filings are current, and that the business name on your policies matches your license record.

Frequently asked questions

Which states took part in the 2026 NASCLA enforcement effort?

According to NASCLA, 15 regulatory agencies from 13 states and the District of Columbia participated from October 12–23, 2026, covering Alabama, Arizona, California, Connecticut, the District of Columbia, Florida, Michigan, Mississippi, Nevada, North Carolina (two agencies), Ohio, Oregon, Utah, and Washington.

Can an unlicensed subcontractor affect my workers’ compensation premium?

It can. Workers’ compensation policies are audited, and payments to subcontractors who cannot show their own valid coverage may be added to your exposure base. In some states, including California, an unlicensed sub and its workers may also be treated as your employees if someone is injured.

Is a certificate of insurance enough to protect me?

A certificate shows that coverage existed when it was issued. It does not add you to the sub’s policy by itself. Pair it with a written subcontract that requires additional insured status, a matching endorsement on the sub’s policy, and a license check in the state where the work happens.

Do these rules only apply to residential work?

No. Licensing rules apply to commercial projects too. Arizona, for example, reported checking residential and commercial job sites and supply houses during the effort. The insurance steps above apply to any project where you hire subcontractors.
