For Arizona excavation workers comp, excavation and grading contractors hold A-5 Excavating, Grading and Oil Surfacing, or the residential R-2 Excavating, Grading and Oil Surfacing. An owner-operator holding 50% or more needs a written election the carrier accepts to be on the policy, and hired operators you control can count as your employees even when paid as subs.
Grading outfits in Arizona often run a small payroll with a lot of outside help: a rented operator for a busy month, haulers paid by the load, a trenching sub for the utility runs. The workers comp statutes care less about what you call those people than about who directs the work.
| Rule | What It Means on a Grading Job | Source |
|---|---|---|
| Supervision or control | An operator or sub doing earthwork that belongs to your trade, under your direction, may be treated as your employee, along with anyone they employ. | Arizona Revised Statutes 23-902 |
| Written contractor agreements | Create a presumption of independent status that the facts on the ground can rebut. | Arizona Revised Statutes 23-902 |
| Owner-operator waiver | An operator working alone as an independent contractor may waive coverage; that operator and your carrier both sign and date the form. | Arizona Revised Statutes 23-961 |
| Owners below 50% | A working LLC member or shareholder under the line is an employee for workers comp. | Arizona Revised Statutes 23-901 |
| Owners at 50% or more | Deemed an employee only on written acceptance by endorsement, at the carrier's discretion, with an assumed wage of at least $600 a month. | Arizona Revised Statutes 23-901 |
| Employee rejection | An employee may reject coverage in writing before an injury; the rule doesn't reach owners. | Arizona Revised Statutes 23-906 |
The ROC license tells the state what earthwork you may contract for. Workers comp classification is a different system, and holding the residential class rather than the commercial one doesn't change how a carrier rates your crew. The Arizona statutory employer rule page applies the same statutes to other trades.
Earthwork payroll in Arizona is sorted using NCCI classifications. Because Arizona offers no official public list we could cite, we leave Arizona code numbers off this site, and your carrier sets the classification after reviewing the jobs. Pad grading, utility trenching, road work and oil surfacing can read very differently to an underwriter, so describe each with the payroll behind it. California's excavation classifications stop at the state line. For how each state organizes its list, see workers comp classification codes.
Illustrative scenario
Illustrative only. A grading LLC licensed under A-5 Excavating, Grading and Oil Surfacing is owned by an operator who holds more than 50% and a minority member who estimates and runs the excavator on busy weeks. For a subdivision job it brings in an operator with their own machine, billed by the hour, and tells that operator where to cut and when. Under Arizona's owner rule, the minority member is an employee and the majority owner is on the policy only through an accepted election. The rented operator may count as an employee under Arizona Revised Statutes 23-902. In Nevada no ownership percentage draws that owner line, and an alarm or cabling license wouldn't fit this work.
Assuming the Majority Owner Is on the Policy
Owners who run equipment often take it for granted that their workers comp policy includes them. In Arizona, a working owner at 50% or more isn't treated as an employee unless the carrier has accepted a written election by endorsement. Check with the carrier where each owner stands, and keep the endorsement with the policy.
Workers comp exists for the injured operator or laborer. A cut gas line, a neighbor's cracked block wall, a loader taken from the yard overnight or a hauling truck in a wreck goes to other policies: general liability, an equipment floater or commercial auto.

The ROC lists A-5 Excavating, Grading and Oil Surfacing for commercial work and R-2 Excavating, Grading and Oil Surfacing for residential work. Check the scope with the Registrar before you bid. Neither license sets your workers comp classification; the carrier works that out from what your crew does.
Possibly. If the digging is part of your own trade and you direct the operator's work, Arizona Revised Statutes 23-902 can make that operator, and anyone they employ, your employee for workers comp. A certificate showing their own coverage, or a sole proprietor waiver they and your carrier have both signed, is what auditors usually ask to see.
Only if you elect in. Arizona counts a working owner at 50% or more as an employee once the carrier signs off on a written election by endorsement. Talk it through with the carrier before the policy starts, since the choice decides what benefits you'd have if you're hurt on a machine.
They can, if they carry no coverage and the hauling is part of your trade under your direction. Before charging premium on them as your employees, the carrier needs written audit findings under Arizona Revised Statutes 23-961, which gives you a chance to produce certificates or waivers.
For licensing, yes: the Registrar keeps separate commercial and residential earthwork classes. For workers comp, the carrier looks at the work itself, so tell it how your payroll splits between house pads, commercial sites and utility trenching.
