Parking and Highway Improvement Contractor Insurance in California (C-32)

What the C-32 license covers

The CSLB’s definition

“A parking and highway improvement contractor applies and installs protective coatings, vehicle stops, guard rails and mechanical devices, directional lines, buttons, markers, signs and arrows on the horizontal surface of any game court, parking facility, airport, highway or roadway constructed of concrete, asphalt or similar material. This classification includes the surface preparatory work necessary for the application of protective coatings but does not include the re-paving of these surfaces.”

Parking lot claims usually come from the public: someone slips on a wet coating, trips on a wheel stop, or a driver blames faded or wrong markings for an accident. Many lots stay open while you work, so the risk starts on day one. Property managers and agencies will ask for additional insured status, and your striping trucks and line machines need coverage on and off the road.

The C-32 coverage stack

General Liability — for slips, trips and marking-related accidents involving the public
Workers’ Compensation — rated 5506, with 9552 for standalone sign work

CSLB license bond — the $25,000 bond every C-32 license needs

C-32 requirements

What California requires of a C-32 licensee

Requirement	What applies to C-32 striping contractors
Contractor’s license bond	A $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’ compensation	Required 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
General liability	Required by the CSLB only for LLC licensees (at least $1 million). General contractors and owners require it anyway, usually with additional insured status.

Workers’ comp class codes and 2026 rates

Class code	Description	Advisory rate per $100 payroll

Striping, traffic markings, wheel stops and similar work on streets and parking lots are rated as street or road construction, 5506, not as painting. Installing signs on their own falls under 9552, a much more expensive code, unless the same crew is paving on that job. Keep sign work separate in your payroll records.

Common questions

C-32 coverage, answered

What is the workers’ comp class code for striping contractors in California?

Painted or thermoplastic lines, traffic markings and wheel stops on streets and parking lots are code 5506, street or road construction, with a 2026 WCIRB advisory rate of $5.60 per $100 of payroll. Standalone sign installation is 9552 ($10.95).

Is general liability required for a C-32 license?

Only for LLC licensees, which must carry at least $1 million. Sole proprietors and corporations aren’t required to by the CSLB, but most general contractors and public agencies will require it before you start.

Am I liable if someone slips on sealcoat in a lot I just finished?

Possibly, and that is a general liability claim. Barricades, signs and clear instructions to the owner help, but the policy is what pays if a claim is made. Check that your policy has no exclusion for the type of work you do.

Do striping contractors need workers’ comp with no employees?

Not yet. A C-32 licensee with no employees can file the CSLB exemption until January 1, 2028, when the exemption ends for every classification. Any employee means you need a policy now.
