California drywall workers comp payroll splits at $45.00 an hour for policies from September 1, 2026: 5446 for workers whose regular hourly wage is below that line and 5447 at or above it. The published titles include finishing as well as hanging, so the wage, not the task, typically decides the side, subject to the carrier's determination.
Drywall contractors hold C-9 Drywall from the CSLB. A drywall business with even one employee needs workers comp. A C-9 licensee working alone can still file a no-employee exemption, but that option is set to close on January 1, 2028 unless the law changes again. The state overview of California workers comp for contractors and restaurants tracks that deadline and the classes already barred from the exemption.
| Rule | What It Means for a Drywall Company | Source |
|---|---|---|
| One employee | Coverage is required as soon as the company has one employee. | CSLB |
| Working alone | A C-9 license holder without employees can still file an exemption until January 1, 2028; the CSLB has proposed keeping a narrower one. | Business and Professions Code 7125 |
| Hangers and tapers without licenses | A worker doing licensed drywall work for you without a license of their own is presumed to be your employee. | Labor Code 2750.5 |
| Penalties | A false exemption or uncovered employees can bring a civil penalty of at least $10,000 per violation for a sole owner or $20,000 for an entity, with later violations up to $30,000 per occurrence. | Business and Professions Code 7125.4 |
| Officers | An officer or director owning at least 10%, or at least 1% when a close relative owns 10% and the officer has health coverage, may waive. | Department of Insurance notice |
Each officer meets the ownership test on their own. Talk through whether an owner stays covered with the carrier before signing a waiver. Crews that also work across the state line answer to different rules, set out in Arizona drywall workers comp quote and Nevada drywall industrial insurance.
The WCIRB publishes drywall as wallboard installation inside buildings, in a pair divided by each worker's regular hourly wage. For policies from September 1, 2026, the line is $45.00. The titles fold finishing and surface preparation ahead of paint into the same work, so a taper and a hanger paid the same typically sit on the same side. The panel lists the published classifications that mention this work; the carrier, not this site, determines how your payroll is reported. The WCIRB class codes for contractors page shows the other wage-split pairs.

Illustrative scenario
A drywall company runs eight people: three hangers and two tapers paid at or above $45.00 an hour, and three laborers who stock board and clean up for less. With hourly records for each person, the five skilled workers' payroll goes in the higher-wage wallboard classification and the laborers' in the lower one, subject to the carrier's determination. In March one laborer is raised past the line, and the payroll records show the date. Hand the same crew a painting job and the line is a different figure; move it to Arizona or Nevada and none of these California codes or thresholds apply, because those states use NCCI classifications.
Keeping Piece Totals without Hours
Drywall shops that pay by the board often record only the piece total. Without hours, an auditor has nothing to compare against $45.00, and the split you estimated at the start of the policy becomes hard to support.
Workers comp answers for injuries to your employees. Water damage behind a wall you closed up, a client's complaint about cracked joints, tools stolen from a job or a truck accident typically falls to other policies, such as general liability, inland marine, commercial auto or a contractor's bond.

For policies effective on or after September 1, 2026, the wallboard pair splits at $45.00 an hour of regular wage: 5446 below it and 5447 at or above it. Each worker's classification depends on the duties and the carrier's determination; we don't assign codes.
Not by task in the published titles, which treat finishing and preparation before paint as part of wallboard installation. What separates them is each worker's regular hourly wage, so a taper and a hanger paid the same rate typically land in the same classification.
The threshold compares a regular hourly wage, and piece pay doesn't show one on its face. Keep hours worked next to piece earnings for each person, and ask the carrier how its auditor will figure the hourly rate before the policy starts, not after the audit.
Today a C-9 license holder who works alone can file an exemption with the CSLB. It is scheduled to end on January 1, 2028, when licensees are expected to keep a certificate on file, with narrow exceptions. The CSLB has proposed changes, so check the current rule.
Painting has its own California pair with a lower line, $36.00. When one worker does both, how the payroll is reported depends on the duties and the carrier's determination. Track hours by type of work so the carrier and the auditor can see the split.
The audit compares each worker's regular hourly wage with $45.00. Raises during the year, an estimate built on one average wage or missing hours behind piece pay can all shift payroll. Ask for the auditor's worksheet and compare it with your own records.
