For Phoenix-area contractors' workers comp insurance, the Arizona rule that moves the most payroll is Arizona Revised Statutes 23-902, the statutory employer rule: subs doing work that is part of your trade, under your supervision or control, may count as your employees. Local pay sets the payroll a carrier rates, and in the Valley servers' and bartenders' median pay runs above cooks'.
Arizona writes its workers comp rules for the whole state, so a business in Phoenix, Mesa or Casa Grande meets the same law. Two things change the answer here: how the statutory employer rule plays out on the Valley's large subcontracted jobs, and the local pay that becomes rated payroll. The table shows the area's median hourly wages by trade, as payroll context.
| Trade or Role | Median Hourly Pay |
|---|---|
| Electricians | $29.43 |
| Plumbers and pipefitters | $30.65 |
| Carpenters | $29.00 |
| Drywall installers | $25.13 |
| Painters | $23.49 |
| Cement masons | $28.49 |
| Equipment operators (excavation) | $30.07 |
| Construction laborers | $22.56 |
| Restaurant cooks | $18.83 |
| Servers | $22.85 |
| Bartenders | $22.57 |
Plumbers, equipment operators and electricians have the highest construction medians in the Valley, with drywall installers, painters and laborers lower. Restaurant pay reads differently: servers' and bartenders' medians sit above cooks' and close to construction laborers'. The BLS estimates include tips. How Arizona counts tips in workers comp payroll isn't covered here, so ask the carrier how it treats them before you estimate a restaurant's payroll.
On the contractor side, Arizona Revised Statutes 23-902 looks at two questions: is the hired work part of your own trade, and do you keep supervision or control of it? Where both answers are yes, the sub and its crew may be counted as your employees. A written independent contractor agreement gives you a presumption that can be challenged, not a final answer, and a sole proprietor you hire can waive coverage only on a form your carrier also signs and dates. The Arizona statutory employer rule page explains owners, waivers and what an auditor needs before charging premium.
The Phoenix metro spans Maricopa and Pinal counties. Maricopa holds Phoenix, Mesa, Chandler, Gilbert, Glendale, Scottsdale, Tempe and Peoria, along with West Valley cities such as Surprise, Goodyear, Buckeye and Avondale. Pinal adds Casa Grande, the city of Maricopa and part of Queen Creek. Most cities run their own building offices, while the two counties permit unincorporated areas. ZIP codes in the list are Census Bureau approximations, close to but not the same as mailing ZIPs.
Semiconductor plants are reshaping north Phoenix: TSMC's first Arizona fab is in production, a second is being fitted out and a third is under construction. Freeway work continues in the West Valley, where the state transportation department is extending Loop 303 south from Van Buren Street and building direct ramps between I-17 and Loop 303, after finishing the I-10 Broadway Curve rebuild. Work at this scale typically runs through layers of subcontractors, which is where the statutory employer rule and certificate tracking come in. We have no connection to these projects; they're listed for local context.
For restaurant owners, Old Town Scottsdale and the Mill Avenue District in downtown Tempe, next to Arizona State University, are restaurant, bar and nightlife districts where tipped service and late shifts shape payroll by role.
Illustrative scenario
Illustrative only. Suppose a Mesa drywall contractor hangs board on a Goodyear apartment job with its own crew and hires a sole proprietor to tape and finish. Finishing is part of the drywall trade, and the contractor sets the schedule and checks the work, so under Arizona Revised Statutes 23-902 the taper may be treated as its employee. With no signed waiver or certificate on file, the auditor may look to add the taper's pay, though Arizona Revised Statutes 23-961 says the carrier must put its audit findings in writing before it bills for that pay. The pay at stake is Valley pay: drywall installers' median here sits below electricians' and plumbers' and above painters'. In Tucson the same taper's typical pay would be lower, and in California the job could bring a wage-based split between two drywall classifications.
Each trade hub below compares Arizona with California and Nevada, including the license class where verified and how the statutory employer rule plays out in that trade. The Arizona contractor workers comp rules page has the state's owner and subcontractor rules, and southern Arizona owners have their own page on workers comp in Tucson.

Not because of the county. Arizona's workers comp law applies the same way in Casa Grande or the city of Maricopa as in Phoenix. Tell the carrier where your crews work and what they do there, since job locations and the type of work feed its underwriting and classification.
It can shape your payroll. In the Phoenix-area BLS figures, which include tips, servers' and bartenders' median pay sits above cooks'. Whether and how tips enter Arizona workers comp payroll is a question for the carrier, and the classification of each role depends on the work done. Split payroll by kitchen, service, bar and office, and the kitchen and server workers comp guide explains why the split matters.
They may be. If framing is part of your trade as a builder and you keep supervision or control over how it's done, Arizona Revised Statutes 23-902 can treat the framing sub and its crew as your employees. A current certificate from the sub, or a waiver signed by a sole proprietor and your carrier, is what an auditor typically asks to see. The subcontractor certificates at audit guide goes through it.
No. Arizona classifies payroll under NCCI's system while California has the WCIRB's, so the codes and wording don't transfer. California also splits several construction trades by hourly wage, and every Phoenix-area construction median in the table sits below the matching California wage line. Tell the carrier before a Valley crew starts work in California.
