In Arizona general contractor workers comp, the state can treat a GC's subs and their crews as the GC's own employees when the GC holds supervision or control over work that belongs to its own trade, a rule that reaches B-1 General Commercial Contractor and B General Residential Contractor licensees alike. Before a carrier charges premium for those workers, Arizona requires written audit findings.
An Arizona GC's workers compensation turns as much on the people it hires as on its own crew: one statute decides when a sub's workers become yours, and another sets how a sole proprietor stays off your policy and what an auditor must put in writing first.
| Rule | What It Means for a GC | Source |
|---|---|---|
| Statutory employer | When you retain supervision or control and the work is part of your trade, subs and their employees are treated as your employees. | Arizona Revised Statutes 23-902 |
| Independent contractor agreement | A written agreement creates a presumption of independent status that the facts can rebut. | Arizona Revised Statutes 23-902 |
| Sole proprietor waiver | A sole proprietor sub may waive coverage as an independent contractor on a waiver that the sub and your carrier both sign and date. | Arizona Revised Statutes 23-961 |
| Audit findings first | Premium on workers treated as yours under those rules can't be charged without written audit findings. | Arizona Revised Statutes 23-961 |
| Owners | Working LLC members and shareholders under 50% are employees; owners at 50% or more join by a written election the carrier accepts. | Arizona Revised Statutes 23-901 |
| Employee rejection | Only in writing, and only before an injury. | Arizona Revised Statutes 23-906 |
| License class | B-1 General Commercial Contractor, B-2 General Small Commercial Contractor, B General Residential Contractor or B-3 General Remodeling and Repair Contractor. | Arizona Administrative Code R4-9-102 and R4-9-103 |
Holding a license class doesn't assign a workers comp class code. The ROC class says what you may contract for; the carrier classifies payroll from what your people do, so a commercial GC with its own carpentry crew may report payroll in more than one classification. The Arizona statutory employer rule page sets the rule beside the state's other requirements.
Arizona classifies GC payroll under NCCI's system. With no official Arizona list open to the public, this site publishes no Arizona codes; the carrier decides from what your superintendents, carpenters and laborers actually do. California's GC classifications don't apply here; see workers comp classification codes for each state's publisher.
Describe Supervision Honestly
A superintendent who also swings a hammer may be reported with the crew. Tell the carrier how field supervisors spend their days; we don't assign or confirm codes.
Illustrative scenario
Illustrative only. A Phoenix B-1 General Commercial Contractor builds a dental office with its own carpentry crew and three subs. The drywall sub hands over a current certificate. The trim carpenter is a sole proprietor whose independent contractor waiver was signed and dated by both him and the GC's carrier. The concrete sub's policy lapsed halfway through the pour schedule, and the GC's superintendent directed the pours. At audit, the drywall and trim work stay off the GC's payroll, while the concrete crew may count as the GC's own workers for the uninsured dates, but only after written audit findings. Move the job to Nevada and the test changes: a licensed principal contractor answers for its subs and their workers, and the independent-enterprise exception doesn't help it.
A Waiver Only the Sub Signed
Many GCs keep a sole proprietor's own signed waiver and stop there. Arizona's waiver needs the signature and date of your carrier as well. Without both, the auditor may count that sole proprietor as your employee when you controlled the work.
If the auditor adds a sub, ask for the written findings. The uninsured subcontractor workers comp audit charge guide explains what to check.
Workers comp answers for injuries to your employees and to workers Arizona treats as yours. Injury to an owner's visitor, damage to the building under construction or a claim about the finished work typically belongs under a bond, builder's risk or general liability. The general contractor workers compensation hub compares the three states, and the Nevada general contractor workers comp page shows the principal contractor rule next door.
Send your trade, state and payroll, and a broker reviews the request. If you would rather talk first, leave a number.

They can be. If you direct or control a sub's work and that work is within your own trade, Arizona treats the sub and its employees as yours. A sub that carries its own coverage for the dates it worked typically answers that question at audit, so collect certificates before the first payment.
A sole proprietor sub can opt out as an independent contractor only on a waiver carrying two signatures and dates: the sub's and your carrier's. Send it to the carrier before the sub starts, not at audit, and keep the signed copy with the job file.
Not without paperwork. Arizona doesn't allow premium on workers pulled onto your payroll under the statutory employer or independent contractor sections until the auditor has put findings in writing. Ask for those findings and check the dates, the duties and who directed the work.
No. B-1 General Commercial Contractor is a license class from the ROC; it doesn't pick a workers comp classification. That comes from your crews' actual work and the carrier's determination, so supervisors, carpenters and laborers may land in different classifications.
Only if you elect it in writing and the carrier accepts that by endorsement, at its discretion. A working partner who owns less than 50% of an LLC or corporation is treated as an employee. Confirm both with the carrier before the policy starts.
It helps but doesn't end the question. A written agreement creates a presumption of independent status that can be rebutted, for example if you set the sub's hours and direct the work. Keep the agreement, and still collect a certificate or a carrier-signed waiver.
