Ornamental Metal and Iron Contractor Insurance in California

Ornamental iron contractors build railings, gates, stairs and fences in a shop, then install them in the field. Gates and railings carry real liability, so we place C-23 contractors with carriers that understand both halves of the work.

What the C-23 license covers

The CSLB’s definition

“An ornamental metals contractor assembles, casts, cuts, shapes, stamps, forges, welds, fabricates and installs, sheet, rolled and cast, brass, bronze, copper, cast iron, wrought iron, monel metal, stainless steel, steel, and/or any other metal for the architectural treatment and ornamental decoration of structures. This classification does not include the work of a sheet metal contractor.”

Welding burns, cuts and lifting heavy pieces are the comp exposures. On the liability side, a railing that gives way or a sliding gate that crushes someone are serious claims, and automatic gates without proper safety devices are a known source of injury lawsuits. Your completed work stays your exposure for years, so make sure your policy includes completed operations coverage.

C-23 requirements

What California requires of a C-23 licensee

RequirementWhat applies to C-23 ornamental metal contractors
Contractor’s license bondA $25,000 bond is required to activate and keep the license. LLC licensees also need a $100,000 LLC employee/worker bond. How the bond works
Workers’ compensationRequired now if you have even one employee. With no employees you can file a CSLB exemption, but that option ends for every classification on January 1, 2028. Check your requirement

Field installation is 5102 and shop fabrication is 3040. The rates are close, but they are separate classes: keep shop and field payroll on separate time records so each hour is rated correctly at audit.

Common questions

C-23 coverage, answered

What is the workers’ comp class code for ornamental iron in California?
Installing ornamental and non-structural metal is 5102 ($6.14 per $100 of payroll in the WCIRB’s 2026 advisory rates), and shop fabrication of ornamental iron, railings and staircases is 3040 ($5.91).
Does my policy cover an injury from an automatic gate I installed?
Completed operations coverage under general liability is what responds to injuries from finished work. Confirm your policy includes it and doesn’t exclude gate or railing work.
Is general liability required for a C-23 license?
Only for LLC licensees, at least $1 million. General contractors and property owners will require it.
Do ornamental metal contractors need workers’ comp with no employees?
A C-23 with no employees can file the CSLB exemption until January 1, 2028. After that every licensee needs a policy.
