California's CSLB C-29 Masonry classification covers concrete units and baked clay products; concrete, glass, and clay block; natural and manufactured stone; terra cotta; refractory work; and certain related masonry construction activities. Review the official CSLB classification before describing the business or relying on a license label.
CSLB explains that construction employers generally need workers' compensation coverage and that licensees may need to provide a certificate, a Department of Industrial Relations self-insurance certification, or a signed exemption when the current facts and classifications permit. CSLB also states that coverage must be continuous and that a lapse can result in license suspension. Employee status, entity structure, actual duties, payroll, and other license classifications should be reviewed before relying on an exemption.
The California Department of Industrial Relations Division of Workers' Compensation provides the state workers' compensation administration and services context. WCIRB provides California workers' compensation classification, experience-rating, advisory pure premium, and educational resources. A C-29 label does not by itself determine a final workers' compensation classification, premium, or coverage result; actual operations, payroll, losses, policy terms, insurer review, and applicable rules must be evaluated.
Before requesting a review, identify whether the business performs C-29 masonry only or also performs C-8 concrete, structural repair, restoration, demolition, or other work. Gather employee and payroll information, subcontractor practices, work trucks and trailers, equipment, project contracts, certificate wording, and prior claims details. Review General Liability, completed operations, commercial auto for work vehicles and trailers, tools and equipment, and contract-specific certificate or additional-insured requirements. A contractor license bond is a licensing item, not a substitute for liability or workers' compensation insurance. Coverage availability, limits, effective dates, pricing, certificates, and eligibility remain subject to complete information, policy terms, carrier requirements, and underwriting.
Review California Workers' Compensation, review Commercial Auto, or request a coverage review with the actual business and license details.
CSLB's definition: “A concrete contractor forms, pours, places, finishes and installs specified mass, pavement, flat and other concrete work; and places and sets screeds for pavements or flatwork. This class shall not include contractors whose sole contracting business is the application of plaster coatings or the placing and erecting of steel or bars for the reinforcing of mass, pavement, flat and other concrete work.” (California Code of Regulations / Business and Professions Code, via cslb.ca.gov).
CSLB's public license file (September 2026) shows 5,281 current C-8 licenses statewide. 93% have a workers' comp policy on file and 0% are filed exempt. 36% are sole owners, 58% corporations and 4% LLCs; 365 were issued in the last 12 months.
Right now 220 C-8 licenses are suspended for workers' comp and 112 for bond problems — a suspended license cannot legally contract.

C-8 is one of the classifications (along with C-20, C-22, C-39, C-61/D-49) that CSLB does not allow to file a workers' comp exemption: every active license must have workers' comp or a valid Certification of Self-Insurance on file, with or without employees.
Concrete flatwork and residential slab and foundation work is generally reported under WCIRB class 5201 or 5205, depending on hourly wage; other concrete construction is generally 5213. The carrier assigns the final code from your actual work.
Every active California contractor license needs a $25,000 contractor license bond on file with CSLB (raised from $15,000 on January 1, 2023). For owners with good credit, the bond commonly costs about $140–$250 a year; price depends mainly on credit.
LLC licenses also need a $100,000 employee/worker bond and liability insurance of at least $1 million (plus $100,000 per member over five, up to $5 million).
