For fencing workers comp insurance, fence construction is classified under each state's own system: WCIRB classifications in California and NCCI in Arizona and Nevada. California's published fence title doesn't divide wood, chain link, vinyl or iron; what tends to change the picture is shop welding, block walls and other work around the fence, as the carrier determines.
| State | Classification System | Rule Worth Knowing |
|---|---|---|
| California | WCIRB | C-13 Fencing holders must insure their first employee, and the exemption for owners working alone is set to close on January 1, 2028. |
| Arizona | NCCI | Arizona can treat a contractor as the employer of a sub's crew when it supervises or controls work belonging to its own line of business. |
| Nevada | NCCI | A principal contractor answers for its subs' employees as if they were its own, and only part of a high earner's pay may count. |
California licenses fence contractors under the C-13 class. A fence company needs coverage as soon as it hires, and a C-13 holder working alone can claim an exemption until January 1, 2028, when the law closes it for most classes. The CSLB has proposed a narrower version, so watch for changes. For the published classification, the audit checklist and the mistakes fence companies make, see California fencing workers comp insurance.
Arizona's statutory employer rule, in Arizona Revised Statutes 23-902, reaches subs: if you retain supervision or control and the job is part of your regular trade, the sub's workers may count as yours. A fence company that subs out post setting or gate welding should collect proof of coverage before the job starts. The owner rules, subs and audit records for Arizona are covered in Arizona fencing workers compensation.
Nevada calls workers comp industrial insurance. Nevada deems subs and their employees to be employees of the principal contractor. A fence company licensed by the Nevada State Contractors Board can't lean on the independent-enterprise exception to avoid that. Since October 1, 2026, Nevada counts each worker's pay only up to a limit set every January: $102,452.16 for policies from January 1, 2027. The payroll limit, owner rules and audit records for Nevada are covered in Nevada fencing workers compensation.
California publishes one classification that names fence construction, and its title doesn't separate wood, chain link, vinyl or ornamental iron. Arizona and Nevada use NCCI classifications for fence work; we don't publish those, and California codes have no standing there. See the workers comp classification codes page for what is listed by state.
Material is often not the turning point; the work around the fence more often is: welding gates in a shop, building block or stone walls, or pouring a retaining wall may each be reviewed under other classifications. The masonry workers comp insurance page explains how block wall work is handled. Wherever the work is done, the carrier decides the classification from the duties performed.
Workers comp is meant for your employees' job injuries, not for damage you cause to others. An auger that hits a buried line, a fence built a few feet onto a neighbor's lot or a crash with a trailer of panels is usually a matter for commercial auto, general liability or a contractor's bond. The sister site walks through insuring the trucks and trailers a fence crew hauls.

In California, the published fence construction title doesn't separate materials. Differences tend to come from the work around the fence, such as shop welding or wall building. In Arizona and Nevada, NCCI classification depends on the work and the carrier's determination.
Not necessarily. Hanging a finished gate on site and building gates and panels in a welding shop are different work, and shop fabrication may be reviewed apart from field installation. List any shop fabrication on your application so the policy matches the work.
No. A code from California's WCIRB system doesn't apply under NCCI in Arizona or Nevada, and each state classifies the fence work done within it.
Nevada treats a principal contractor as the employer of its subs and their employees, so an uninsured sub's crew may become your responsibility under your industrial insurance. Ask every sub for a current certificate before work starts.
Fence quotes often differ because of the work around the fence. Gate welding in a shop, block or stone walls and retaining walls may fall under other classifications, and a low quote that treats all of it as installation can be revised at audit. Compare which duties each quote names, how subs are handled and what certificates you can get quickly. See the cheapest workers comp insurance guide.
